    [0001] The invention relates to an assembly comprising a first part and a second part and a device for positioning the first part relative to the second part. In the aeronautical sector, the assembly of the sleepers (the sleepers constitute the structural part of a floor of the aircraft) to frames which constitute the primary structure of the fuselage must be made accurately. Each crossbar which is generally of great length (several meters) is brought into correspondence, via its two opposite ends, respectively with two opposite points of the inner periphery of each frame. The opposite ends of the cross member and the respective attachment points of the frame, which are generally pre-drilled prior to being matched, are then drilled and assembled in situ. When sometimes sensitive equipment (because incorporating electronic components and electrical elements) have already been brought inside the primary fuselage structure, the drilling operations that are performed later generate chips, dust that are susceptible to pollute this equipment. It would therefore be useful to be able to remedy this problem, which is likely to arise both in the aeronautical sector and in other industrial sectors. SUMMARY OF THE INVENTION The object of the present invention is therefore to provide an assembly comprising a first and a second component and a device for positioning the first component relative to the second component, the first component having a free end provided with at least one a first bore and the second part having a latching portion provided with at least one second bore adapted to correspond to said at least one first bore, characterized in that said at least one first bore and said at least one second bore are drilled to their definitive diameter prior to their relative positioning, the device comprising at least one positioning element which is able to position, according to at least one geometric axis, said at least one first bore relative to said at least one second bore. The bores having been previously drilled to their final diameter they do not require additional drilling.

A precise positioning of the bores relative to each other is then necessary since the parts are already at the final dimensions of the assembly. The positioning of the bores takes place according to at least one geometric axis, which can in certain circumstances make it possible to simultaneously or almost simultaneously position the two geometric axes. According to other characteristics taken separately or in combination with each other: said at least one positioning element is able to position, according to a first geometric axis, said at least one first bore relative to said at least one second bore; the device comprises positioning means which are capable of positioning said at least one first bore relative to said at least one second bore, along a second geometric axis (Z); The device comprises positioning means which are capable of positioning said at least one first bore relative to said at least one second bore, along a third geometric axis (Y); the first geometric axis is parallel to the axis of said at least first and second bores; Said at least one positioning element is a centering element along the first axis of the first piece relative to the second piece; - The centering element is disposed above the attachment portion of the second part; - The centering element is a pad, for example removable, the upper portion forms a wedge; the positioning means comprise at least one positioning element of said at least one first bore relative to said at least one second bore and following the second geometric axis (Z); the said at least one positioning element is placed below the attachment part of the second part; said at least one positioning element is a wedge, for example a removable one; the positioning means comprise several geometrical marks arranged on the first piece and on the second piece and which are intended to be aligned with each other along the second geometric axis (Z) and / or the third geometric axis (Y) ; the positioning means comprise at least one tool which is capable of bringing the geometric reference or references of a part into alignment with the geometric reference (s) of the other part along the second geometric axis (Z) and / or the third geometric axis; said at least one positioning element of said at least one first bore relative to said at least one second bore, along the first geometric axis or the second geometric axis, is disposed on at least one of the two parts; The positioning means comprise: at least one active member disposed on one piece; at least one passive member disposed on the other piece and which is able to cooperate with said at least one active member by transmission and reception of electromagnetic waves, a closed-loop control system which is able to control the electromagnetic waves transmitted and the movement of at least one room relative to the other as a function of the waves received by said at least one passive organ geometrically matching said at least one active and passive member; The positioning means comprise several geometrical landmarks arranged on the first piece and on the second piece and which are intended to be aligned with each other along the second geometric axis (Z) and / or the third geometric axis (Y) . the first and third geometric axes are arranged in the horizontal plane and the second geometric axis is the vertical axis; - the first piece is a cross and the second piece is a frame; - The cross is intended to be fixed at two diametrically opposite points of the inner periphery of the frame respectively via its two opposite ends, one of which is the free end not yet fixed of the cross and the other is the opposite end already fixed at one point of the frame; the device comprises means for compressing the frame which are able to exert a compression force on the frame so as to bring the two diametrically opposite points of the inner periphery of the frame closer to one another; the free end of the cross-member comprises a yoke aligned in the longitudinal axis of the cross-member and the attachment portion forms a peg disposed on the inner periphery of the frame.

The object of the invention is, in yet another aspect, a method of positioning a first piece relative to a second piece, the first piece having a free end provided with at least one first bore and the second piece having a first piece. gripping part provided with at least a second bore intended to come into correspondence with said at least one first bore, characterized in that said at least one first bore and said at least one second bore are drilled to their definitive diameter beforehand their relative positioning, the method comprising a step of positioning, along at least one of the three geometric axes, of said at least one first bore relative to said at least one second bore.

Other features and advantages will become apparent from the following description given solely by way of nonlimiting example and with reference to the appended drawings, in which: FIG. 1 is a general perspective view of a together according to an embodiment of the invention; Figure 2 is a side view of the assembly of Figure 1; Figures 3 to 5 illustrate the mounting of a free end of a cross member to a fuselage frame; - Figures 6 to 8 illustrate the positioning of the opposite free end of the cross of Figures 3 to 5 relative to the frame, along a first geometric axis X, according to one embodiment; - Figures 9 and 10 illustrate the positioning of the opposite free end of the crosspiece of Figures 3 to 5 relative to the frame, along a second geometric axis Z, according to one embodiment; - Figures 11 to 13 illustrate the positioning of the opposite free end 5 of the cross of Figures 3 to 5 relative to the frame, along a third geometric axis Y, according to one embodiment; - Figure 14 is schematic sectional view in a horizontal longitudinal plane of the opposite free end of the cross member assembled to the attachment part of the frame; Figure 15 is a schematic perspective view of an aircraft fuselage primary structure including sleepers attached to fuselage frames; FIGS. 16 to 19 illustrate the positioning of the opposite free end of the crosspiece of FIGS. 3 to 5 relative to the frame, according to the second z and third geometric axis y according to another embodiment. The present invention applies in particular in aeronautics to the positioning of a first part such as an aircraft cross member (intended to form, together with other crosspieces, the structural part of a floor of an aircraft) by relative to a second fixed part such as a frame of a primary aircraft fuselage structure, hereinafter referred to as a fuselage frame. FIG. 1 illustrates in an enlarged and partial manner: a crossbar T which has a free end provided with at least one first bore; a fuselage frame C which comprises a hooking or fastening part provided with at least one second bore. The free end 12 of the cross member (as its opposite end not visible in Figure 1) is configured in the form of screed aligned in the direction of longitudinal extension of the crossbar. The free end 12 of the cross member comprises a bore which is drilled in each of the two parallel arms 12a, 12b of the yoke. The first two bores a 1, a 2 are aligned along a single axis which is perpendicular to the direction of longitudinal extension of the cross member T. The attachment portion 14 is arranged on the inner peripheral edge of the frame C and is configured in the form a post extending radially inwardly of the frame. The pin 14 is pierced with a second bore a3 perpendicular to the plane in which the frame C extends. The bores a 1, a 2, a 3 are pierced in the parts before they are put into place in the primary fuselage structure. These bores already have the final diameter required for subsequent assembly of the parts and therefore do not require any additional drilling or grinding operation. The positioning of the parts whose dimensions are final must be precise so that they can be assembled. This task is all the more complicated / delicate as the sleepers are long pieces. In the position shown in Figure 1, the free end 12 of the cross member 15 is disposed near the attachment portion 14 of the frame, above it, for the relative positioning of the parts. A device 20 for positioning the cross-member T relative to the frame C is used in order to geometrically match very precisely (within a few tenths of a millimeter) the first two bores a1 and a2 with the second bore a3. The positioning device 20 provides the relative positioning along three geometric axes, namely a first geometric axis X (horizontal axis), a second geometric axis Z (vertical axis) and a third geometric axis Y (horizontal axis). The Z and Y axes are contained in the plane of the frame and are perpendicular to the axes of the bores a1, a2 and a3, while the X axis is parallel to said axes of the bores. The device 20 comprises: a first element 22 for positioning the first two bores a1, a2 with respect to the second bore a3 along the first geometric axis X; means 24, 27, 28, 29 for positioning the first two bores a1, a2 with respect to the second bore a3 along the second axis (Z) and the third geometric axis (Y).
    [0002] The first positioning element 22 has the function of ensuring the centering of the cross member, and therefore of the first two bores a1, a2, relative to the frame, and therefore to the second bore a3. The first element 22 is arranged, for example in a removable manner, above the pin 14 to come into special contact with the free end 12 of the cross member which is generally brought from above. The first centering element 22 is, for example, an insert (eg shoe) having a wedge shape 22a in its upper portion which is intended to cooperate with the free end of the crosspiece. The lower portion 22b or base of the pad 22 is widened to have a better seat on the upper portion 14a of the pin 14. The pad is, for example, glued to the tenon. The aforementioned positioning means more particularly comprise a second positioning element 24 which is able to position along the second axis Z the first two bores a 1, a 2 (already positioned along the first axis X) relative to the second bore a 3. This second positioning element 24 is arranged, for example removably, below the pin 14 to act as a vertical stop at the free end 12 of the crossbar. The second element 24 is for example a wedge which is mounted in the portion 14b of the stud located under the bore a3. The wedge has, for example, a U-shape whose opening is engaged on the aforementioned lower portion 14b of the post and the two branches of the U thus frame this portion. The positioning means also comprise a plurality of geometrical landmarks arranged partly on the free end 12 and partly on the post 14. These geometrical landmarks are intended to be aligned with each other along the third axis Y, provided that the first bores a1 and a2 and the third boring a3 have been positioned relative to one another along the first axis X and the second axis Z. The alignment of the geometric references with the third axis Y ensures the relative positioning of the bores a. , a2, a3 along this axis. The geometric marks take for example the form of pins, two of which 27, 28 are respectively formed on the upper face of each of the two arms 12a, 12b of the free end (on either side of the notch formed between these arm), vertical to the central axis of the bores al and a2. A third lug 29 is formed on the upper portion of the post, vertically to the central axis of the bore a3. The pad 22 is positioned recessed 5 relative to the lug 29, between the latter and the inner peripheral edge of the frame to which it is leaned. As illustrated in Figure 2, the positioning means further comprises a tool 30 which is positioned above the free end 12 of the cross member. This tool is able, on command, to bring the 10 geometric marks 28, 27 and 29 in geometric correspondence or in alignment along the third axis Y. The tool 30 is, for example, a pincer readjustment clip which can be hydraulic, electric, manual type, depending on the value of the readjustment effort to be made. The tool is further optionally provided with a force limiter to secure the parts. A method of positioning the cross member T relative to the frame C and its assembly with it will now be described with reference to FIGS. As shown in FIG. 3 (cross-section of an aircraft fuselage primary structure), the cross-member T is first attached to an attachment or attachment portion 15 of the frame C (identical to the part of FIG. hanging 14). To do this, the free end 17 in the form of a screed of the cross member (identical to the end 12) is brought from above (FIG. 4) and lowered to introduce the protruding part 15 of the frame into the notch formed between the arms apart from the yoke 17. Once thus positioned (Figure 5), the free end 17 and the portion 15 are assembled by bolting into the bores in correspondence of the two parts. FIG. 3 illustrates the crossbar T attached to only one of its ends while the other free opposite end 12 is waiting for positioning and assembly with the part 14 of the frame. The gap between the end 12 and the part 14 of the frame has been deliberately exaggerated for the purposes of illustration. In practice the offset is of the order of a few millimeters. The positioning of the free end 12 of the cross member relative to the attachment portion 14 of the frame uses the positioning device 5 described with reference to FIGS. 1 and 2. FIGS. 6 to 8 successively illustrate the positioning of the free end 12 (clevis) relative to the fastening portion 14 (peg) along the first geometric axis X. The free end 12 is brought above the fastening portion 14 10 and descended vertically (manually or with a lifting / lowering device) so that the yoke comes into contact with the first positioning element 22. As illustrated in FIG. 7, one of the two arms 12a, 12b of the yoke touches one of the edges slope of the upper corner 22a of the pad and slides on the latter as the cross goes down. This has the effect of positioning the two arms 12a, 12b of the yoke on either side of the pad, thus centering it on the pad (Figure 8). The first bores al and a2 are thus positioned relative to the second bore a3 along the first axis X. In FIGS. 7 and 8, the positioning defect of the bores along the third axis Y is apparent (the positioning defect along the second axis Z is also present but not visible). FIGS. 9 and 10 successively illustrate the positioning of the free end 12 relative to the hooking portion 14 along the second geometric axis Z. In the example described, the free end 12 has already been positioned relative to the piece 14 along the first axis X. The relative positioning defect of the bores a1, a2, on the one hand, and the bore a3, on the other hand, along the two axes Z and Y is apparent in FIG. T cross continues its descent until the lower face 12a1, 12b1 of the arms of the yoke comes into contact with the second positioning element 24 (wedge), in particular with the legs of the U that forms the wedge. This second element 24 thus forms a stop along the second axis Z (FIG. 10). In the position illustrated in FIG. 10, the bores a 1, a 2 and a 3 have been positioned relative to each other along the second axis Z.
    [0003] Only the positioning defect remains on the third axis Y. It will be noted that the first positioning element 22 has, for example, been dismounted as soon as the free end 12 of the crossbar has descended below the altitude of this element (Figures 9 and 10).
    [0004] Figures 11 to 13 illustrate successively the positioning of the free end 12 relative to the attachment portion along the third and last geometric axis Y (this axis corresponds to the longitudinal axis of the cross member). This last positioning step is implemented by the tool 30 of Figure 2 which is, for example, a clamp clamped on the cross member, for example on the two longitudinal flanks recessed thereof. The body 32 of the tool is mounted in a locked manner on the upper longitudinal edges of the flanks whose flank, denoted 40, shown in FIG. 11. The head 34 of the tool comprises gripping members 36 which are adapted to to lock on the two lugs 27, 28, on the one hand, and the lug 29, on the other hand, and to move relative to each other in order to bring the lugs 27, 28 in alignment (Along the X axis) with the lug 29. In a manner not shown in the figures, the gripping members 36 comprise, on the one hand, one or more first gripping members which are able to lock on the two pins 27, 28 and, secondly, one or second gripping members which are adapted to lock on the lug 29. The first members are able to move relative to the second members (or vice versa) along the axis Y by means of drive means (motor ...) integrated in the tool, for example the body 32 3 0 of the latter, and controlled (by an external command on the tool or remotely) to drive in motion the first members relative to the second members (or vice versa) along the Y axis.
    [0005] In practice, the tool exerts a traction along the Y axis on the lug 29 to bring it in geometric correspondence with the lugs 27 and 28, thereby making the frame C in compression shown in FIG. 3 (the frame has a certain flexibility in its design by design and because it is adapted to withstand the forces due to the pressurization of the aircraft cabin in flight). The lugs 27, 28 are centered (by design) precisely on a vertical axis which passes through the center of each of the two first bores a1, a2.
    [0006] The lug 29, for its part, is centered (by design) precisely on a vertical axis passing through the center of the second bore a3. Given this arrangement, the alignment of the three lugs 27 to 29 ensures the positioning of the three bores relative to each other along the third axis Y.
    [0007] FIGS. 12 and 13 respectively show, in side and top view, the relative final positioning of the bores along the three geometric axes X, Z and Y. With such a positioning, the bores are in geometric correspondence with one another in a zone of given tolerance, for example to a few tenths of a millimeter. A screw of the conical tip type 42 (FIG. 14) is then inserted into the bores in order to perfect the centering of said bores with one another. This screw 42 is for example implemented by a pulling tool which bears on the inner face of the hollow body of the screw.
    [0008] A nut 44 is then mounted on the open end of the screw 42 which is located opposite the head of said screw. Once assembled, it is no longer necessary to compress the frame C with the tool 30. The positioning just described is particularly effective and fast. The parts having been previously drilled to their definitive diameter and therefore no longer require in-situ drilling operation (in the aircraft structure being integrated or assembled) but only a relative positioning of the parts, this represents a significant time saving. Moreover, the fact of no longer drilling in-situ avoids generating dust and chips in an environment where are sometimes already installed equipment (eg electronic equipment) sensitive to such pollution. In addition, this simplifies drilling operations insofar as the tools and materials needed to make them are often bulky and therefore difficult to integrate into the environment of the aircraft being integrated or assembled with a density equipment often high. Note that all the cross members of the structural part of the floor 10 of the aircraft can be positioned and assembled on their respective frame identically either one after the other or simultaneously. FIG. 15 schematically represents an aircraft fuselage primary structure denoted S comprising several frames C and several crosspieces T each extending between two diametrically opposite fixing points on the internal periphery of each frame. The sleepers were positioned and assembled as described above. FIGS. 16 to 19 illustrate another embodiment of a device 50 for positioning the first part (crossbeam) T relative to the second part (frame) C. This device 50 comprises the first positioning element 22 shown in FIGS. Figures 1, 2 and 6 to 9 which is used in the same way (positioning along the first axis X). The device 50 (FIG. 16) also comprises positioning means which comprise: two active members (also called active targets) 52, 54 arranged on the crossbar T, a passive member (also called a passive target) 56 which is arranged on the frame C and which is adapted to cooperate with the two active members 52, 54 by transmission and reception of electromagnetic waves. The active members 52, 54 are able to transmit electromagnetic waves and the passive member 56 is able to receive them. The organs may be, for example, magnetic targets. As shown in FIG. 17, the device 50 also comprises a closed-loop control system 60. The system 60 is able to control, on the one hand, the electromagnetic waves transmitted by the active members 52, 54 and, on the other hand, on the other hand, as a function of the waves received by the passive member 56, the relative displacement of the cross member with respect to the frame so as to bring the active and passive members in geometric correspondence. These organs can also be considered as geometric landmarks present on the parts and that one seeks to bring in geometric correspondence with each other. The system 60 more particularly comprises a control and control unit 62 which is connected to the active and passive components, on the one hand, and to a tool 64, on the other hand. The tool 62 can be integrated into the tool 64 The tool 64 comprises a body 66 mounted in a locked manner on the top and on the two recessed longitudinal flanks (for example: sidewall 40) of the cross member, as for the tool 30. The tool 64 also comprises a head 68 fixed to a body 66 and which comprises gripping members 70 intended to be locked on the geometrical markings (eg pins) 27 to 29 of the cross member and the frame. The gripping members 70 are controllable remotely by the unit 62: - for locking / unlocking them on the geometrical landmarks; 20 -for their displacement along the second (Z) and third axes (Y) as indicated by the arrows in Figure 17 to move the free end 12 of the cross relative to the attachment portion 14 of the frame. All that has been said about tool 30 of FIG. 11 also applies here to tool 64. As with tool 30, tool 64 exerts an axial pull on frame C (compression). of the frame). It will be noted that the active members 52, 54 are, for example, made in the form of pellets respectively inserted into the bores a1 and a2 (FIG. 16) of the yoke 12. The same applies to the passive member 56 inserted in The method according to this embodiment of positioning the cross member relative to the frame starts, as for the previous method, a positioning along the first axis X by means of the first positioning element 22 (FIG. centering element).
    [0009] Once this first positioning has been performed, the device 50 described above is implemented in order to align the pins 27 to 29 (along the X axis) with one another and thus to geometrically correspond to the Z axes. and Y the bores a1, a2, on the one hand, and a3, on the other hand.
    [0010] More particularly, the control and control unit 62: - controls the transmission of electromagnetic waves / signals by the active organs 52, 54, - receives information from the active organs as a function of the position of the passive member 56 by ratio to the active organs and, therefore, according to the return of the signals emitted by the active organs and reflected by the passive organ processes this information (and in particular deduces the difference between the respective positions of the active and passive organs as a function of the waves / signals received), and transmits to the tool 64 a control adapted to cause a displacement of the gripping members 70 corresponding to the difference between the positions thus determined (displacement of the gripping members locked on the portion 14 relative to the gripping members locked on the crossbar), - repeats the cycle of the preceding steps until an alignment of the positions of the active and passive members i corresponds to a geometrical matching of the bores a1, a2 and a3 along the two axes Z and Y. FIG. 18 is a sectional view showing the arrangement of the active members 52, 54 on both sides of the passive member 56 when these members have been placed in their respective housings (bores a1, a2, a3) and that their positions have been aligned along the three geometric axes. Figure 19 illustrates the positioning of the two parts along the three geometric axes. After geometric matching of the active and passive members, the active members 52, 54 are removed, while the passive member 56 is driven away when the screw 42 of FIG. 14 is put in place. example to constitute a sacrificial organ. The embodiments described above first provide for positioning along the first axis X with the first positioning element 22, then positioning along the other two axes Z and Y with the second positioning element 24 and the geometric marks. According to a first variant not shown, the positioning takes place along the first axis with the first element 22 and, during this positioning, the positioning is obtained simultaneously along the two other axes without involving either the second element 24 or the geometric marks 27 to 29. The positioning device can thus be considerably simplified since it is reduced to the first element 22.
    [0011] Note however that a second variant not shown can take the first variant by adjusting geometric landmarks on the two parts (such pins 27 to 29) to control the correct positioning of parts. According to a third variant, not shown, the relative positioning of the pieces can take place only along the second (Z) and third axes (Y) while passing from the first positioning element 22. In this case, the cross member is directly mounted. by its clevis on the tenon of the frame. According to a fourth variant, not shown, the embodiment illustrated in FIGS. 16 to 19 can be simplified by omitting the first positioning element 22 as for the third variant. According to a fifth variant not shown, the number of active and passive organs, their location and shape may vary. These bodies can also be reported on the parts after construction, removably or not, or be integrated into said parts during their construction. According to a sixth variant not shown, other elements or shapes arranged in relief on one and / or the other part (crossbar, frame) can be envisaged to put one of the parts in geometric reference with respect to the other room. According to a seventh variant not shown, the shape, the location and the number of the elements 22, 24 and 27 to 29 may vary while each ensuring the same function (s). The elements or some of them can be removable or not.
    [0012] According to an eighth variant not shown, the locations of the yoke 12 and the post 14 can be reversed: the yoke is integral with the frame and the tenon is secured to the cross. According to a ninth variant not shown, the yoke and the tenon 5 may be replaced by other attachment means or complementary interlocking to ensure the assembly of a cross on a frame. According to a tenth variant, not shown, a tool is used to bring into geometric correspondence along one or more geometric axes 10 geometrical landmarks present on the two parts to be positioned and which are different from the pins identified in the figures described above. Note that the two parts to be positioned relative to each other may be other parts of an aircraft, or parts used in a parts assembly in other industrial sectors (maritime, railway, building ...). One and / or the other of these parts can be mobile for at least part of the duration of implementation of the method of positioning a part relative to the other.
