    [0001] The present invention relates to a control gauge for controlling at the output of the production line that dimensional characteristics of a fastener are in accordance with the design plane of the fastener. More particularly, the invention relates to a control ring for attachment of the type comprising an enlarged head and a cylindrical shaft extending along an axis, the shaft having at least one coating strip parallel to the axis. Such a fixing is described in application FR 3,008,754 and shown in FIGS. 1A and 1B. This type of fastener is used to assemble metal structures and composite aircraft. FIGS. 1A and 1B show a metal fastener 10 of the aforementioned type, viewed respectively at the end and at the side, comprising a protruding head 12, a cylindrical drum 14 and a threaded portion 16. In a variant, the fastening may comprise a pulling tail allowing pull on the fastener to insert it into interference in a previously bored structure. This tail may be an integral part of the fastener 10, or removable by means of a threaded end inserted into a threaded end made inside the threaded portion 16. Alternatively, the threaded portion may be replaced by grooves annular crimping. Alternatively, the head 12 may be milled. The barrel 14, intended to come into tight contact in a bore made in a set of structures comprising one or more materials, metallic and / or composite, comprises four conductive portions 20, that is to say which do not comprise any coating or paint preventing the passage of an electric current between the conductive portion of the barrel and the wall of the bore. The barrel also comprises four lubricating strips 22, arranged parallel to the axis of revolution A of the fastener. Each lubricating strip 22 extends on the barrel 14 and on a portion under the head 12, over a distance X. The conductive and lubricating portions 22 are arranged alternately around the circumference of the barrel, as shown in FIG. 1A. Thus, the electrical conduction is ensured over the entire thickness of the assembled structure, regardless of the composition of the structure in which the fastener is inserted. Lubricating portions 22 provide lubrication drum 14 over its entire height so that the attachment can be installed interference without seizing or breaking.
    [0002] The lubricant used may be a MoS2 type solid film, or an organic aluminum pigmented resin, such as HI-KOTE ™ 1 or HI-KOTE ™ 1 NC coating marketed by Hi-Shear Corp. in Torrance, California, both dielectric. The lubricant is deposited in a thickness of 5 to 13, for example by spraying, over an axial length and over a width given to the design plane of the fastener 10. Whatever the method of manufacturing a fastener 10 and the means For the deposition of the lubricating belts 22, the dimensional characteristics of these belts, especially the lengths and widths, must be measured and compared to that of the fastener design plane in order to ensure compliance. Various dimensional measurement means are known which make it possible to control the dimensions of the strips 22, which are specified on the design plane of the fastener. A first means is a three-dimensional means, which makes it possible to control the dimensions by palpating the fastener. A second known means is a computer means comprising a camera that films the fixations and analyzes the images with respect to a reference image. These means are reliable but expensive to purchase and maintain, bulky, fragile and require specially trained staff.
    [0003] An object of the present application is to provide dimensional control means for the lengths and widths of lubricating strips of prior art fasteners which is easy to manufacture, simple and fast to use, which wears little and is reliable . The invention therefore relates to a control ring intended to control a fastener comprising an enlarged head and a cylindrical shaft extending along an axis, the shaft comprising at least one coating strip parallel to the axis, the band extending over a circumferential width. The ring comprises a cylindrical tubular body extending along an axis of revolution between a first end and a second end, characterized in that the first end comprises two adjacent arc segments, each arc segment having a wall of end extending in a plane perpendicular to the axis of revolution of the ring, the planes of the two walls being not merged and axially offset from the first end, and each arc segment comprises at least one side wall s' extending in a radial plane passing through the axis of revolution of the ring, and in that a width of an arc segment is defined by a minimum bandwidth to be controlled, and a cumulative width of the two arc segments is defined by a maximum bandwidth to be controlled. There is thus obtained a simple device for dimensional control of characteristics of a fastener. Such a device proves on the one hand inexpensive to manufacture, by machining or molding in any type of material, is little subject to wear in use, practically foolproof and without need for periodic calibration, and can be worn and set implemented by any operator having to carry out a control before laying a fastener. The choice of a material of low hardness relative to the material of the fasteners also limits the risk of producing damage, for example a scratch, on the fastener.
    [0004] The control ring according to the invention may include one or more of the following features in consideration of all technically possible combinations. In one embodiment, the two adjacent arc segments are notches extending axially in the tubular body to the end walls, located between the first end and the second end. In another embodiment, the two adjacent arc segments are projections extending axially out of the tubular body to the end walls beyond the first end. The choice of one or other of these embodiments, which can be combined on the same ring, is in particular dictated by conditions of use, for example lighting conditions and / or contrast conditions. reading, or even a comfort preference of a user. In one embodiment, at least a portion of a sidewall of a notch or projection extends in a plane offset from a radial plane of the body with an angle (a). This results in an optical reading facilitated given the possible thickness of the body of the ring. In one embodiment, the second end of the ring has at least one notch extending axially on a portion of the body from said second end to a first end wall, an axial length of the notch being defined by a minimum distance to be controlled between said second end and an axial end of the strip disposed on the barrel of the fastener. In one embodiment, the second end also has at least one second notch extending axially on a portion of the body from said second end to a second bottom wall, an axial length of said second notch being defined by a tolerance range of a distance to be controlled between said second end and an axial end of the strip disposed on the barrel of the fastener. It is thus obtained on length or end position checks of 10 bands the same advantages as for the control of the bandwidths. In one embodiment, to adapt to the shape of the head of the fastener, the second end comprises a conical or flat surface, complementary to a respectively milled or protuberant fixing underside.
    [0005] In one embodiment, the second end comprises a tapered surface and a flat surface alternately complementary to a milled or protruding underbase. In order to facilitate the interpretation of the checks carried out and to limit the risks of misreadings, at least one end or side wall comprises a visual means indicating acceptance or rejection of the checked dimension. The visual means is for example a color applied to said wall or an indication applied to said wall. The invention also relates to a method of controlling a fastener 25 comprising a head and a cylindrical shaft extending along an axis, the shaft having at least one coating strip parallel to the axis, the strip extending over a circumferential width of the barrel, by means of a control ring of the invention, the method comprising the following steps: a) loosely mounting the ring on the cylindrical barrel of the fastener, b) rotating the ring circumferentially of the barrel so as to align a first edge of a strip with a side wall of a first arc segment of the first end, c) declare the circumferential width of the conforming strip if a second edge of the strip, opposite the first edge of said band, is included in the second arc segment and is not included in the first arc segment, that is, if the width of said band is greater than the width of the first arc segment; first arc segment and lower than the first arguer of the two adjacent arc segments. It is thus verified the conformity of a width of a band on the barrel of the fixation. In one embodiment, steps b) and c) performed for one strip are repeated for each of the fastening strips of the fastener, and the fastener is declared non-compliant if step c) is not checked for at least one coating strip.
    [0006] It is thus possible to carry out complete control of a fastener by a simple rotation of the fastener relative to the ring. The invention also relates to a control of a fastening comprising a head and a cylindrical shaft extending along an axis, the shaft comprising at least one coating strip parallel to the axis, the strip extending over a length, by means of a ring according to the invention, the method comprising the following steps: a) mounting with play the ring on the cylindrical barrel of the fastener, b) slide the ring so as to put the second end abutting under the head of the fastener, 20 c) rotate the ring over the entire circumference of the barrel, d) declare the fastening according to a criterion of maximum length of the bands if no band appears in the first notch during the rotation of the Ring. It is thus verified the conformity of a length of the strips on the barrel of the fixing. In one embodiment, the method further comprises a step of declaring the conformal fastening according to a criterion of minimum length of the bands if the axial end of each band appears opposite the second notch.
    [0007] In one embodiment, the second end of the ring is placed in abutment under a head of the fastener. It is thus limited the risk of a defect of positioning of the ring on the shaft of the fastener during a tape length control.
    [0008] The invention and its various applications will be better understood on reading the description which follows and on examining the figures that accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show: FIG. 1A: an end view of a fastener of the prior art to be controlled, already described; - Figure 1B: a side view of a fastener of the prior art to control, already described; FIG. 2 is an isometric view of a first embodiment of a control ring; FIG. 3 is an isometric view of a second embodiment of a control ring; FIG. 4 is an isometric view of a third embodiment of a control ring; FIG. 5 is an isometric view of a fourth embodiment of a control ring; FIG. 6 is an end view of the ring of FIG. 2 disposed on the barrel of a fastener to be inspected, FIG. 7 is another end view of the FIG. 2 ring disposed on the barrel of FIG. fixation to be tested, the barrel having rotated 90 ° in the anti-clockwise direction with respect to FIG. 6. FIG. 2 represents a first embodiment of control ring 100 according to the invention. The control ring 100 comprises a tubular body 110 of axis of revolution B, provided with a through bore, opening on a first end 120 of said tubular body and a second end 140 opposite the first end. The ring is for example made of aluminum. The inside diameter of the ring corresponds to the outer diameter of the barrel 14 of the fastener to be checked, with a close play so that the ring can slide without excessive resistance on the barrel 14.
    [0009] The first end 120 of the body comprises two U-shaped notches 122 and 124 extending axially on a portion of the body 110 from the end 120 towards respectively an end wall 126 and an end wall 128. The end walls 126 and 128 extend in parallel planes, perpendicular to the B axis, and are axially offset from each other. The two notches 122 and 124 are adjacent and have different axial lengths, and widths - or arc segments - of different lengths. The terms "width" and "arc segments" will be used interchangeably throughout the remainder of the description and refer to the length of the arc segment covered by the lubricating strip. The notch 122 comprises two side walls 130 and 132 and the end wall 126. The wall 132 is disposed in a radial plane, that is to say a plane extending parallel to a radius of the ring and passing by the axis of revolution B of the ring. The wall 130 includes a radially extending portion 130A (Fig. 6, 7) and a beveled portion 130B extending in a plane radially offset by an angle α (Fig. 6, 7). ). The bevel facilitates visual control. In variant not shown, the entire wall 130 could be beveled. The width of the notch 122 between the side walls 130 and 132 corresponds to the minimum authorized width of a strip 22. The width of the two notches 122 and 124, between the side walls 130 and 134, corresponds to the maximum width allowed. The width of the wall 128, between the side walls 132 and 134, represents the tolerance range accepted in the design plane of the fixing of the width of the strip 22. The difference in axial length of the notches 122 and 124 is not used to measure an axial strip dimension 22, but makes it possible to visually differentiate the two minimum and maximum widths represented by the side walls of the notches. To facilitate the use of the ring, the word "GO" is inscribed on the body 110 under the end wall 128, visually indicating the acceptable tolerance range of the measured bandwidth. Alternatively, the end wall 128 could comprise a color, for example a green color, visually indicating the acceptable dimensional range. The second end 140 comprises in this embodiment a planar surface without notch.
    [0010] Figure 3 shows a ring 100B according to a second embodiment of the invention. The ring 100B comprises a body 110B and a first end 120B, identical to the first end 120 of the first embodiment shown in FIG. 2. In the example of FIG. 3, the second end 140B of the ring 100B 35 comprises a notch 142B extending axially over a portion of the body 110B from the end 140B to an end wall 144B extending in a plane perpendicular to the axis B of the ring 100B. The notch 142B includes two side walls 146B and 148B, and the end wall 144B. The side walls 146B and 148B are each arranged in a radial plane. A portion 145B of the body 110B is tapered to facilitate visual inspection. The notch 142B is only necessary when the band 22 does not extend to the sub-head radius 13 of the attachment, but stops at a precise distance from the sub-head radius. For this specific case, the notch 142B extends axially over a distance corresponding to the minimum distance indicated in the design plane of the fastening between the underside of the head and the axial end of the strip 22. The width of the Notch 142B must be sufficient to allow visual control, but is not used to measure the correct width of the coating tape. The second end 140B comprises a flat surface 150B, intended to come into contact with the underside of a protruding head fastener. The inner wall of the end 140B includes a shoulder 152B, adapted to receive the sub-head radius 13 of a protruding head fastener. To facilitate the use of the ring, the word "GO" is inscribed on the body 110B near the side wall 146B near the second end 140B, visually indicating the acceptable dimensional range of the measured length. Alternatively, the side wall 146B could comprise a color, for example a green color, visually indicating the acceptable dimensional range of the measured length. FIG. 4 represents a ring 100C according to a third embodiment of the invention. The ring 100C comprises a body 110C, a first end 120C and a second end 140C. In contrast to the ring shown in FIG. 2, the first end 120C of this embodiment does not include a U-shaped notch, but two U-shaped projections 122C and 124C, also adjacent, extending axially outwardly. beyond the end 120C to respectively an end wall 126C and an end wall 128C. Projection 122C includes two side walls 130C and 132C, and end wall 126C. The wall 132C is disposed in a radial plane. The width of the projection 122C between the side walls 130C and 132C corresponds to the minimum authorized width of a strip 22. The width of the two projections 122C and 124C, between the side walls 130C and 134C corresponds to the maximum authorized width of a The width between the side walls 132C and 134C represents the tolerance accepted in the design plane of the fastener 10.
    [0011] The difference in the length of the projections 122C and 124C in the axial direction is not used to measure an axial strip dimension 22, but allows to visually differentiate the two minimum and maximum widths represented by the side walls of the projections.
    [0012] To facilitate use of the ring, the word "GO" is inscribed on the body 110C of the ring under the end wall 128C, visually indicating the acceptable dimensional range of the measured width. Alternatively, the end wall 128C could comprise a color, for example a green color. The words "NO GO" denoting the rejection of the fastener are inscribed with the side wall 130C and under the end 120C, near the wall 134C, visually indicating the unacceptable dimensional range of the measured width. Alternatively, the flat surface of the end 120C and the side wall 130C could comprise a color, for example a red color, visually indicating the unacceptable dimensional range of the measured width. These indications are optional, and the caliber may comprise only a "GO" indication or a green color, or a "NO GO" indication or a red color. The second end 140C of the ring 110C comprises a flat surface without a notch. Alternatively not shown, it may comprise a notch 142B as shown in Figure 3, or a series of notches 142D, 152D and 162D 20 shown in Figure 5 and described below. FIG. 5 represents a ring 100D according to a fourth embodiment of the invention. The ring 100D comprises a body 110D and a first end 120D identical to the first end 120C of the ring 100C, shown in Figure 4. Alternatively, it may be identical to the first end 120C of the ring 100C.
    [0013] In the example of FIG. 5, the second end 140D of the ring 100D comprises a series of three successive U-shaped notches 142D, 152D, 162D, extending axially on a portion of the body 110D from the end 140D. to respectively three end walls extending in planes perpendicular to the axis B, and axially offset from each other. The three notches 142D, 152D and 162D are symmetrical with respect to a radial plane passing in their middle, the radial planes midpoints of the three notches being merged. Each notch includes two side walls and an end wall. The sidewalls are each arranged in a radial plane. The widths of the notches are larger and larger as the end walls 35 are near the end 140D. The use of successive and adjacent notches 3038044 10 of different widths makes it possible to physically mark the tolerance range by shifting the lateral walls of each notch in the radial direction. The axial length of the first notch 142D represents the minimum distance which must separate the sub-head radius 13 from an attachment of the axial end of a band 22. This notch is equivalent to the notch 1428 of the ring 1008 The axial length of the second notch 152D and the axial length of the first notch 142D thus represents the tolerance range of the distance between the sub-head radius 13 of a fastener and the axial end of a strip 22. The third notch 162D extends axially beyond a distance greater than the maximum distance indicated in the fastener design plane, between the underside 13 and the axial end of the strip 22. The widths of the notches 142D , 152D and 162D must be sufficient to allow visual inspection, but are not used to measure the width of a lubricating strip, in order to avoid control errors.
    [0014] To facilitate use of the ring, the word "GO" is inscribed on the body 110D near the side wall of the second slot 152D, visually indicating the acceptable tolerance range of the measured tape length. Alternatively, the side wall of the second notch could include a green color. The ring may comprise other visual indications, such as the word "STRAW" to indicate that the ring is adapted to a countersunk fastener, a "NO GO" indication to the side walls of the notches 142D and 162D to indicate that a band whose axial end appears in these ranges is out of tolerance. Alternatively, the indication "NO GO" may be replaced by a red application on the side walls of these notches.
    [0015] The method of measuring the dimensions of a coating strip 22 on a barrel of a fastener 10 by means of a ring 100, 1008 or 100C or 100D will now be described in connection with FIGS. 6 and 7. 6 and 7 show the measurement of a width of a coating strip 22 of a fastener 10 by means of a ring 100, represented in FIG.
    [0016] The ring 100 is shown in plan view, and the barrel of the fastener is shown in section. The lubricating strips are schematically illustrated and exaggeratedly enlarged. The method comprises the following steps, which may be performed in a different order, since the non-compliance of a dimension results in the non-compliance of the fastener.
    [0017] The first step is to mount with play the ring 100 on the cylindrical shaft 14 of a fastener to control. The operator then rotates the ring over the entire circumference of the barrel so that a band 22 'to be checked appears in the two notches 122 and 124.
    [0018] For this, he aligns the wall 130A of the notch 122 with one end 22'a of the strip. In the case of the strip 22 ', the second end 22'b of the strip appears between the wall 132 of the notch 122 and the wall 134 of the second notch 124. The width of the strip 22' is therefore in the tolerance range as defined by the width of the end wall 128, since it is both wider than the minimum width required, and narrower than the maximum width allowed. The width of the band 22 'being in conformity, the operator rotates the ring 100 on the barrel 14 of the fastener to control the adjacent cladding strip 22 "This position is represented in FIG.
    [0019] As before, the operator aligns the wall 130A of the notch 122 with an end 22 "a of the web, and in the case of the web 22", the second end 22 "b of the web does not appear between the web. wall 132 of the notch 122 and the wall 134 of the second notch 124. The width of the band 22 'lies outside the tolerance range defined by the width of the end wall 128, since it is wider the maximum width allowed, it is therefore not in accordance with the design plan, and the fastener 14 is checked as non-compliant If the second end 22 "b of the strip 22" terminates in the width of the notch 122 before the wall 132, then it would also be judged to be non-compliant since it was smaller than the minimum width allowed, the fastener 14 would therefore also be deemed non-compliant If all the belts 22 are judged to be in conformity, the controlled fastener 14 is also judged to be in conformity to the design plan. 100C to measure the conformity of the band widths 22 is similar to that previously described, with the difference that the operator must align the end 22'b or 22 "b of a band with the wall 130C of the protrusion 122C, and check whether the end 22'a or 22 "a of the band appears in the width of the wall 128C of the second projection 124C. If the end 22'a or 22 "a does not appear, either because the band is too narrow or because it is too wide, the band does not conform and the fastener is judged to be non-compliant.
    [0020] If the fastener 14 comprises strips 22 which do not extend over the entire length of the barrel 14 but extend over only a portion of the barrel, away from the sub-head radius 13 of the fastener 10, the ring 1008 or 100D is necessary. For this, the operator mounts for example the ring 100B on the barrel 14 of the cylindrical fixing, and 5 slides the ring until the second end 140B of the body comes into abutment under the head of the fastener. If the fastener 10 is protruding head, the second end 140B requires a flat portion to be pressed under the protruding head 12. If the fastener 10 is countersunk, the second end 140B requires a conical portion.
    [0021] The operator then rotates the ring over the entire circumference of the barrel to visually check whether each band 22 appears in the notch 142B. If a band 22 does not appear, then the attachment is controlled as non-compliant: indeed, the band 22 is too far from the underside of the head and its length does not conform to the plan. If all the bands appear, then the attachment is controlled according to the plan. The notch 142B controls only the minimum distance between an under-head radius 13 and an axial end of a web 22. If the fastener design plane 10 specifies that the webs 22 should be at a distance within a range tolerance of the sub-head radius, then the operator will use the ring 100D shown in Figure 5. The control method is identical to that described above, except that the axial end of a strip 22 must appear opposite of the side wall of the second notch 152D to be considered compliant. If the axial end of a band 22 appears opposite the third notch 162D, then the band is too short. If the axial end of a band 22 appears opposite the first notch 142D, then the band is too long. In both cases, the tape length is not in accordance with the plan, and the fastener is considered non-compliant. Advantageously, a ring will include bandwidth control means at the first end, and two bandwidth control means at the second end, one adapted for a countersunk attachment, the other adapted for a fastener with protruding head. Thus, a single ring makes it possible to quickly perform several checks. The ring 100B or 100D can be used to control fasteners without requirement on the axial strip length, using only the visual bandwidth control means.
    [0022] 3038044 13 Such a ring is simple to manufacture, not usable since the side walls are not rubbed, and easy to use with GO / NO GO markings or color codes applied to or on the walls of control. Of course, this ring can be used to measure widths and strip lengths of any type of coating, not just lubricating strips.
