    A method for aligning two orifices (22, 24) respectively belonging to two parts is based on the use of a tool (30), comprising a body (32) having a first external surface (36) which moves progressively a longitudinal axis (34) of the body moving away from a first end (38) of the body, and a hollow part (18) having a second outer surface (40) of section complementary to the section of the orifices. The hollow part includes an orifice (43) by which it is removably mounted on the tool so that the second outer surface (40) extends the first outer surface of a side opposite the first end of the body. The method includes inserting the first end of the body into the first port (22), and then operating the tool to urge the body and then the hollow part together into the orifices. This method applies in particular to the assembly of a floor module to an aircraft fuselage.

    METHOD FOR ALIGNING A FIRST ORIFICE OF A FIRST PART WITH A SECOND ORIFICE OF A SECOND PART AND KIT FOR IMPLEMENTING IT
    DESCRIPTION
    TECHNICAL AREA
    The present invention relates to a method of aligning a first port of a first part with a second port of a second part, the first and second ports having respective respective sections.
    This method is particularly applicable to aircraft parts. For example, one of the parts may be an aircraft floor cross, the other part then being a circumferential aircraft fuselage frame.
    STATE OF THE PRIOR ART
    In known methods of assembling aircraft, the floor crosspieces are integrated piece by piece in a purely structural environment. Their mode of implementation, including including machining operations of fixing holes, in fact prohibits the presence of nearby system elements, because of the vulnerability of such elements.
    However, it is possible to integrate several floor crossings at the same time, with relatively fragile systems present nearby. For this purpose, it is desirable to be able to avoid machining operations of the fixing holes at this stage of the assembly, and thus to achieve the assembly by means of previously machined fixing holes.
    However, the manufacturing tolerances of the parts do not make it possible to guarantee that the pre-machined fixing orifices will align with each other with sufficient accuracy to ensure a good structural connection, such precision being typically of the order of a few hundredths of a millimeter.
    Similar considerations apply with respect to the assembly of other types of modules of the aircraft.
    DISCLOSURE OF THE INVENTION The invention aims in particular to provide a simple, economical and effective solution to this problem.
    To this end, it proposes a method of aligning a first orifice of a first part with a second orifice of a second part, the first and second orifices having respective respective sections, the process comprising the steps of: providing a tool, comprising a body centered along a longitudinal axis and having a first external surface which progressively moves away from the longitudinal axis away from a first end of the body, and providing a hollow piece having a second outer surface of complementary section to the section of each of the first and second orifices and of longitudinal extent greater than a depth of the first orifice, the hollow part comprising an orifice by means of which the hollow part is removably mounted on the tool so that the second outer surface extends the first outer surface of a side opposite to the first At the end of the body, position the first piece and the second piece so that the first and second holes are at least partially facing each other, then - insert the first end of the body into the first hole, and then maneuver the tool so as to push the body of the tool and the hollow part together in the first orifice and then in the second orifice, then - separate the body of the tool and the hollow part so that the hollow part remains housed in the first port and in the second port.
    The section variation of the first outer surface of the body of the tool allows, as the body progresses through the orifices, to progressively align these orifices.
    The method according to the invention thus provides an effective means for aligning initially off-axis orifices.
    In its particular application to the assembly of aircraft modules to the structure of an aircraft, the method according to the invention makes it possible to avoid the implementation of machining operations during assembly and thus allows to limit the risks of damaging the systems fitted to such modules. Since the orifices used for assembling the parts can be machined before the assembly operations, the latter can indeed be summarized in simple bolting operations or the like.
    Preferably, the hollow part has a base, and the step of operating the tool is carried out until the base of the hollow part is applied to the first part.
    In a preferred embodiment of the invention, the body of the tool has a longitudinal orifice which passes therethrough, the orifice of the hollow part is a through hole, the tool comprises a traction screw comprising a rod having a threaded portion and a head, and the tool comprises a traction device comprising a bearing surface and a nut integral with the bearing surface. The nut is configured to cooperate with the threaded portion of the rod, as will become more apparent in the following.
    In the preferred embodiment of the invention, the method comprises a step of inserting the draw screw shaft into the hole of the hollow piece and into the longitudinal bore of the body of the tool, so that the tool body and the pull screw head sandwich the hollow part, and so that the threaded portion of the rod protrudes from the body of the tool beyond the first end of the body.
    In the preferred embodiment of the invention, the method comprises a subsequent step of applying the support surface of the traction device against the second piece, on a side opposite the side of the first piece.
    In the preferred embodiment of the invention, said step of maneuvering the tool is a step of screwing the threaded portion of the rod into the nut of the traction device so as to cause a translation of the traction screw through the first and second holes by a "screw-nut" effect.
    In addition, the traction device advantageously comprises antifriction means which block the nut of the traction device in rotation during said step of maneuvering the tool.
    Preferably, the hole of the hollow part has a tapping, and the method comprises a subsequent step of screwing a fixing screw into the hole of the hollow part so as to apply a head of the fixing screw on the second piece and tighten the first part and the second part together.
    Preferably, the body has an extension having an external thread and extending beyond the first outer surface, on the opposite side to the first end of the body, and the method comprises a prior step of mounting the hollow piece in a removable on the tool by screwing the extension of the body in the hole of the hollow part.
    In a particular application of the method, one of the first and second parts is an aircraft floor transom and the other of the first and second parts is a circumferential aircraft fuselage frame. The invention also relates to a kit comprising, on the one hand, a tool comprising a body centered along a longitudinal axis and having a first external surface which progressively moves away from the longitudinal axis while moving away from a first end of the body, and secondly, at least one hollow part having a second external surface and comprising an orifice by means of which the hollow part can be removably mounted on the tool so that the second outer surface extends the first outer surface on one side opposite to the first end of the body.
    Preferably, the body has a longitudinal orifice which passes through it, the orifice of the hollow part is a through orifice, the tool comprises a pulling screw comprising a rod adapted to pass through the orifice of the hollow part and the orifice longitudinal portion of the body and having a threaded portion, and a head, and the tool comprises a traction device, comprising a bearing surface, and a nut secured to the support surface, spaced from the latter, and configured to allow screw the threaded portion of the rod into the nut.
    Preferably, the bearing surface extends orthogonally to the longitudinal axis of the body when the threaded portion of the rod is screwed into the nut.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
    FIG. 1 illustrates a part of an aircraft fuselage 10 comprising in particular circumferential frames, as well as an aircraft floor module 12 comprising in particular floor rails, before assembling the module to the fuselage. FIG. 1 shows, in particular, two lateral portions of one of the circumferential frames 13 and a floor cross member 14.
    FIG. 2 illustrates the same elements after assembly of the module 12 at the fuselage, and makes it possible in particular to see the floor cross member 14 fastened to the two lateral portions of the circumferential frame 13. For this purpose, the lateral portions of the circumferential frame 13 have respective mounting plates 16 which project from the frame towards each other and which each have a respective first hole, and the floor cross member 14 has two opposite ends each provided with a second orifice respective.
    Fixing each of the two ends of the floor cross member 14 to the corresponding fixing plate 16 is carried out by means of a corresponding hollow part 18 forming a nut (FIG. 3), housed jointly in the corresponding first hole of the floor crossmember 14 and in the second hole of the corresponding mounting plate 16, and by means of a corresponding fastening screw 20 screwed into the hollow part 18 (Figure 4). The assembly of the module 12 to the circumferential frames, however, requires a very precise alignment of the first and second orifices, which the manufacturing tolerances do not allow to obtain initially, as illustrated in FIG. 5, in which the misalignment of a first orifice 22 and a corresponding second orifice 24 is greatly exaggerated for purposes of illustration, the magnitude of the misalignment being typically of the order of a few millimeters. A realignment of these orifices is therefore necessary a posteriori. The invention proposes for this purpose a method of aligning a first orifice of a first piece, such as the orifice 22 of the floor cross member 14, with a second orifice of a second piece, such as the orifice 24 of the corresponding mounting plate 16.
    This method is based on the use of a kit comprising a tool 30 in association with at least one hollow part such as the hollow part 18 above. In general, the tool 30 comprises a body 32 centered along a longitudinal axis 34 and having a first external surface 36 which progressively moves away from the longitudinal axis 34 away from a first end 38 of the body 32 (Figures 6, 7 and 15). In other words, the first outer surface 36 has a flared shape from the first end 38 of the body 32.
    In addition, the hollow part 18 has a second external surface 40 of section substantially complementary to the section of each of the first and second orifices 22, 24 and of longitudinal extent L1 greater than the depth d1 of the first orifice 22 and preferably equal to or greater than to the sum of the depth d1 of the first orifice 22 and the depth d2 of the second orifice 24 (FIG. 7). By "substantially complementary section", it should be understood that the section of the second outer surface 40 may have a complementary section or diameter slightly greater than the section of each of the first and second orifices 22, 24, to allow a tight fitting or to interference of the hollow part 18 in the orifices 22, 24, as will become clearer in what follows.
    Finally, the hollow part 18 is removably mounted on the tool 30 so that the second outer surface 40 extends the first outer surface 36 on a side opposite the first end 38 of the body 32, as will become more clearly apparent in FIG. what follows. It should be understood that the second outer surface 40 extends in the continuity of the first outer surface 36, that is to say without forming a recess with the latter.
    In the preferred example illustrated, the body 32 has a symmetry of revolution about the longitudinal axis 34, that is to say that it has at all points a circular cross section centered on the longitudinal axis 34 (FIGS. 6, 7 and 15). The diameter of this section naturally increases along the longitudinal axis 34 from the first end 38 of the body 32.
    In addition, the hollow part 18 takes the form of a flange nut, and therefore has a base 42 and a through hole 43 provided with a tapping. Indeed, in the preferred embodiment of the invention, the method comprises a final step of clamping the two parts by means of the hollow part 18, as will become clearer in what follows.
    The through character of the orifice 43 is intended to allow the passage of a traction screw for operating the tool 30, through the hollow part 18, as will become clearer in the following.
    Alternatively, the orifice 43 may not be through, when another type of means is provided for operating the tool 30. The orifice 43 is in this case a blind hole opening on the side of the body 32 of the tool when the hollow part 18 is mounted on the tool 30.
    In another variant, the method according to the invention may not include the final step of clamping the two parts, and the hollow part 18 may be a simple centering sleeve or the like. If necessary, the tightening of the two parts 14 and 16 can then be ensured later, for example by bolting through the centering sleeve.
    In the illustrated embodiment, the body 32 has an extension 46 having an external thread 48 and extending beyond the first outer surface 36, the opposite side to the first end 38 of the body. The external thread 48 is configured to be screwed into the tapping 44 of the hollow part 18.
    Furthermore, in the preferred embodiment of the invention, the body 32 has a longitudinal orifice 50 which passes through it from one side.
    In addition, the tool 30 comprises a traction screw 52 comprising a rod 54 having a threaded portion 56 and a smooth portion 57, and a head 58. The threaded portion 56 and the head 58 are arranged on either side of the smooth portion 57. The tool further comprises a traction device 60 (Figures 8 and 15), having a bearing surface 62 and a nut 64 integral with the bearing surface 62. In the example shown, the traction device 60 comprises a flat ring 66 on which is formed the bearing surface 62 and which is connected to the nut 64 by arms 68 of arcuate shape between them a space for receiving the body 32. The nut 64 and the flat ring 66 are arranged coaxially, so that the bearing surface 62 extends orthogonally to a screw axis defined by the nut 64 (coinciding with the longitudinal axis 34 in the figures).
    In addition, the traction device 60 comprises antifriction means which may for example take the form of a first anti-friction washer 70 (visible in Figure 15 only).
    The steps of the alignment method according to the preferred embodiment of the invention are illustrated in FIGS. 7 to 14.
    Initially, the first orifice 22 and the second orifice 24 are partially facing each other but are off-axis, as shown in FIGS. 7 and 7a.
    The method comprises a preliminary step of mounting the hollow part 18 removably on the tool 30 by screwing the extension 46 of the body 32 in the hollow part 18, then a step of inserting the smooth portion 57 of the rod 54 the draw screw 52 in the longitudinal hole 50 of the body 32, so that the body 32 of the tool and the head 58 of the draw screw sandwich the hollow part 18, and so that the threaded portion 56 of the rod protrudes from the body 32 of the tool beyond the first end 38 of the body, as shown in Figures 6 and 7.
    More specifically, the body 32 has a shoulder 72 (Figures 7 and 15) which connects the extension 46 of the body to the first outer surface 36, and which forms a stop with respect to the hollow part 18 preventing movement of this last relative to the body 32 parallel to the longitudinal axis 34.
    In the illustrated example, a second anti-friction washer 74 (visible only in FIGS. 6 and 15) is interposed between the head 58 of the traction screw 52 and the hollow part 18, to limit the friction between the head 58 of the screw and the hollow part 18 during the subsequent operation of the tool 30, and thus avoid damaging the hollow part 18.
    It should be noted that the longitudinal orifice 50 has a smooth inner surface to allow rotation of the rod 54 with respect to the body 32.
    In the example shown, the head 58 of the pulling screw 52 has an imprint 76 hexagonal. Other shapes of heads are of course possible without departing from the scope of the invention.
    Figure 6 thus shows the assembly formed of a portion of the tool 30 and the hollow part 18 in its state at the end of the previous process steps described above.
    The method then comprises a step of: applying the bearing surface 62 of the traction device 60 against the second piece 16, on a side opposite to the side of the first piece 14 (FIG. 8), then the body 32 of the tool being positioned on the side of the first part 14, to insert the threaded portion 56 of the rod 54 of the pulling screw 52 and the first end 38 of the body 32 into the first orifice 22, then to operate the tool 30 so as to push the body 32 of the tool and then the hollow part 18 together in the first orifice 22 and then in the second orifice 24.
    The operation of the tool 30 is carried out by screwing the threaded portion 56 of the traction screw 52 into the nut 64 of the traction device 60, preferably by means of an electric screwdriver.
    Due to the rotational locking of the nut 64 thanks to the anti-friction means, in this case the first anti-friction washer 70 of FIG. 15, the screwing of the traction screw 52 into the nut 64, symbolized by the arrow R of FIG. 8 gives rise to a reaction F tending to apply the bearing surface 62 of the traction device 60 to the second component 16, and thus causes a translation T of the traction screw 52 through the first and second orifices 22 , 24 by a "screw-nut" effect.
    As a result, the head 58 of the draw screw 52 pushes the body 32 and then the hollow piece 18 through the first and second orifices 22, 24.
    The variable-section shape of the first outer surface 36 of the body 32 then makes it possible, as the body 32 advances through the orifices 22, 24, to progressively align these orifices, as shown in the figures 8 to 12.
    At the end of this step of maneuvering the tool 30, the hollow part 18 is housed jointly in the first and second orifices 22, 24 (FIG. 12). In the preferred embodiment of the invention, the base 58 of the hollow part 18 is then applied to the first part 14.
    In addition, the body 32 of the tool is housed in the space between the arms 68 of the traction device 60. In particular, the bearing surface 62 surrounds the body 32 of the tool. In general, other forms are possible with regard to the bearing surface 62 and the means which connect it to the nut 64. The bearing surface 62 may, for example, not be a continuous surface such as in the illustrated example, but be formed of several separate surfaces. It is therefore possible that the bearing surface 62 does not surround the body 32 at the stage of the method described above with reference to FIG. 12 but, in any case, in any plane of section passing through the longitudinal axis 34, the bearing surface 62 extends at a distance from the longitudinal axis 34 greater than the distance separating the second external surface 40 of the hollow part 18 and the longitudinal axis 34 to allow the passage of the body 32.
    The method is continued by a step of dissociating the body 32 from the tool and the hollow part 18, leaving the hollow part 18 housed in the first orifice 22 and in the second orifice 24, as shown in FIG. For example, the step consists in removing the traction device 60 by unscrewing its nut 64 from the threaded portion 56 of the traction screw 52, then pulling the head 58 of the traction screw 52 so as to remove the traction screw 52 of the body 32, then finally to remove the body 32 by unscrewing the extension 46 thereof from the hollow part 18.
    In the preferred embodiment of the invention, the method comprises a subsequent step of screwing the fixing screw 20 into the hollow part 18 so as to apply a head 92 of the fixing screw 20 to the second piece 16 (FIG. 14). The base 42 of the hollow part 18 and the head 92 of the fixing screw 20 thus mutually tighten the first part 14 and the second part 16.
    The mounting of the hollow part 18 in the orifices 22, 24 can thus be achieved with a high fitting accuracy, which allows an optimal transfer of shear forces between the two parts 14 and 16.
    Optionally, additional traction bolts (not visible in the figures) can be used near the orifices 22, 24 to ensure a good plating of the first piece 14 on the second piece 16 and thus guarantee the effectiveness of the work. shearing of the hollow part 18. For this purpose, these traction bolts are mounted with a large clearance in the corresponding orifices of the two parts 14 and 16.
    In addition, the orifices 22 and 24 may be formed directly in the parts 14 and 16, as in the example described above. Alternatively, these orifices 22 and 24 may be formed in rings themselves mounted in orifices formed in the parts 14 and 16. In general, the method and the kit according to the invention thus provide an effective means for align initially misaligned holes.
    In their particular application to the assembly of aircraft modules to the structure of an aircraft, the method and the kit according to the invention make it possible to avoid the implementation of machining operations during assembly. and thus limit the risk of damaging the systems fitted to such modules. The assembly can indeed be summarized in simple bolting operations.
    In the particular case of the application of the method and the kit according to the invention to the attachment of the floor cross member 14 to the circumferential fuselage frame 13, the method according to the invention makes it possible to put the circumferential frame 13 under a slight constraint by deforming it sufficiently to make the orifices 22 of the floor crosspiece coincide with the corresponding orifices 24 of the plate 16 of the circumferential frame 13.
