    [0025] DETAILED DESCRIPTION OF EMBODIMENTS In the following description, the terms relating to a position are taken with reference to a tool holder disposed on a surface of a workpiece, i.e. as it is shown in FIG. 1. FIG. 1 shows a tool holder 100 which is positioned and fixed on a surface 52 of a workpiece 50 to undergo a particular treatment using a tool carried by said tool holder 100. The treatment can be for example drilling of the piece 50, the installation of an insert, .... The tool set up is then adapted to this treatment.
    [0026] The tool holder 100 comprises: a first rail 102a and a second rail 102b parallel and each having first fastening elements 112 configured to secure said rail 102a-b to the surface 52, a driving slide 104, 30 a driven slide 106, an assembly bar 108, and a support module 110 (not shown in Fig. 1, see Figs 9 and 10). Since the tool holder 100 is more particularly designed to be used on an outer surface of an aircraft fuselage, the rails 102a-b 3033273 7 each have a flexibility and a curvature that are suitable for being applied on such a curved outer surface. In the rest of the description, the so-called 'plane of the rails' is the surface which is parallel to the surface 52 of the part 50. The plane of the rails can then be flat in the case of a flat or curved surface 52 in the case of a 5 52 curved surface. The longitudinal direction of the rails 102a-b is represented by the arrow 54. If the surface 52 is flat, the longitudinal direction of the rails 102a-b takes the form of a line parallel to said surface 52, and if the surface 52 is curved the longitudinal direction of the rails 102a-b takes the form of a curve parallel to said surface 52. FIG. 2 and Figs.
    [0027] 3A and 3B show the driving slide 104 mounted on the first rail 102a and comprising: a frame 202 carrying first guide members 302 having a guide position in which the first guide members 302 are configured to provide a slide connection between the driving slide 104 and the first rail 102a, - a drive system 204 configured to move the driving slide 104 along the first rail 102a, and - a first attachment system 206 whose operation is described below .
    [0028] FIG.
    [0029] 4A-C and Figs.
    [0030] 5A-B show the driven slide 106 mounted on the second rail 102b and which comprises: - a frame 402 carrying second guide elements 502 having a guide position in which the second guide elements 502 are configured to provide a slide connection between the driven slide 106 and the second rail 102b and a second fastening system 406 whose operation is described later with the assembly bar 108. FIGS. 6, 7 and 8A-B show the assembly bar 108 which comprises a frame 606 of elongate shape, a first end of which carries a first complementary fixing system 602 intended to cooperate with the first attachment system 206 so as to form a removable attachment between them, a second end of which carries a second complementary fastening system 604 intended to cooperate with the second fastening system 406 so as to form a fastening 3033273 8 removable between them, and a carriage 801 mounted to move in translation along the 606 of the assembly bar 108 and having a first assembly system 802. Figs. 9 and 10 show the support module 110 comprising second fastening elements 1002 for attaching the tool to the support module 110, and a second assembly system 902 for cooperating with the first assembly system 802. so as to form a removable attachment between them. It is said that a first piece is removably mounted on a second piece when the first piece can be detached from the second piece without any of the parts being damaged.
    [0031] The modularity of the tool holder 100 facilitates its assembly and disassembly, as well as the verification of each element constituting the tool holder 100 independently of others and its possible restoration or replacement. The first fastening elements 112 are for example suckers distributed along each rail 102a-b and which are applied on the surface 52. The first fastening elements 112 may also be a series of magnets secured to each rail 102a. when the piece 50 is metallic. The drive system 204 includes an electric motor and a gear 320 (seen in the partial section of FIG.
    [0032] 3A) which is rotated about a rotational axis by the motor and meshes with slots 216 of the first rail 102a. The rotary axis is parallel to the plane of the first rail 102a and perpendicular to the longitudinal direction of the first rail 102a. Thus, when the motor is activated, the gear wheel 320 rotates and its teeth meshes with the slots 216 to move the driving slide 104 in one direction or the other in the direction of rotation of the motor.
    [0033] The first 302 and second 502 guide members are constituted by four grooved wheels 304a-d, respectively 504a-d, two of which are arranged along a first longitudinal edge of the first rail 102a, respectively second rail 102b, and two of which are arranged along a second longitudinal edge of the first rail 102a, respectively second rail 102b. Each longitudinal edge of the rail 102a-b 30 is positioned in the bottom of the grooves of the corresponding throat wheels 304a-d, 504a-d which thus enclose the rail 102a-b, thus ensuring the creation of a slide connection and preventing the separation of the slider 104, 106 of the rail 102a-b. Each grooved wheel 304a-d, 504a-d is rotatable about its axis.
    [0034] Since the rails 102a-b may be curved, the axis of rotation of each grooved wheel 304a-d, 504a-d is oriented to ensure the rotation of said grooved wheels 304a-d, 504a-d. d and tracking the rails 102a-b by said grooved wheels 304a-d, 504a-d during the movements of the driving slides 104 and led 106 5 along the curved rails 102a-b. More generally, the first 302 and second 502 guide members comprise at least three grooved wheels 304a-d, 504a-d, at least two of which are arranged along a first longitudinal edge of the first rail 102a, respectively second rail 102b, and of which at least one is disposed along a second longitudinal edge of the first rail 102a, respectively second rail 102b. In another embodiment not shown, the first and second guide elements comprise a groove parallel to the rail 102a-b and in which the edge of said rail 102a-b is inserted and, in the bottom of the groove, a succession rollers with an axis perpendicular to said rail 102a-b and against which rolls said edge.
    [0035] The first guide members 302 are disposed here under a bottom 250 of the driving slide 104 which extends in a plane locally parallel to the plane of the first rail 102a. The second guide elements 502 are arranged here under a bottom 450 of the driven slide 106 which extends in a plane locally parallel to the plane of the second rail 102b.
    [0036] The introduction of the driving slide 104 and the driven slide 106 can be effected by placing them at the ends of the first rail 102a and the second rail 102b and sliding each slide 104, 106 to the desired position. . To facilitate this implementation, the first guide members 302 are movable from the guide position to a release position in which they do not provide the slide linkage and separate the leading slide 104 from the first rail 102a. In the release position, the first guide members 302 are remote from the edge of the first rail 102a. For this purpose, the driving slide 104 includes a first actuating system 208 configured to ensure the passage of the first guide members 302 from the guide position to the release position, and vice versa. Fig.
    [0037] 3B shows the grooved wheel 304c in the release position where it is disengaged from the longitudinal edge of the first rail 102a. Likewise, the second guide members 502 are movable from the guide position to a release position in which they do not provide the slide connection and separate the driven slide 106 from the second rail 102b. In the release position, the second guide members 502 are spaced from the edge of the second rail 102b. For this purpose, the driven slide 106 includes a second actuating system 408 configured to ensure the passage of the second guide members 502 from the guide position to the release position, and vice versa. Fig.
    [0038] 5B shows the grooved wheel 504c in the release position where it is disengaged from the longitudinal edge of the second rail 102b. To clear the rail 102a-b from the grip of the grooved wheels 304a-d, 504a-d, Figs.
    [0039] 3A-B and Figs.
    [0040] 5A-B show that the grooved wheels 304c-d, 504c-d which are along the same longitudinal edge of the rail 102a-b deviate from said rail 102a-b to release said longitudinal edge. Of course, it is possible to provide that all grooved wheels 304a-d, 504a-d deviate from each of the longitudinal edges. In general, to ensure the passage of the guide position to the release position, at least one of said at least two grooved wheels 15 or said at least one grooved wheel is movable from the guide position to the release position in which the at least one group is at a distance from the rail and thus does not ensure the slide connection and allows to separate the leading slide 104, respectively led 106, of the first rail 102a, respectively second rail 102b, disengaging the rail 102a-b of the throat. The first actuating system 208 is thus configured to pass said at least one group from the guiding position to the releasing position, and vice versa, and the second actuating system 408 is thereby configured to ensure the passage of said guiding position. at least one group from the guiding position to the releasing position, and vice versa. The first 208 and the second 408 actuating systems comprise a first 210, respectively second 410, handle movable by a user from a lock position to an unlock position and, for the 304c-d grooved wheels, 504c-d movable, a first 306, respectively second 506, shift system movable between a guide position in which said grooved wheels 304c-d, 504c-d are in the guiding position and a release position 30 in which said wheels groove 304c-d, 504c-d are in the release position, and a first 214, respectively second 514, transmission system configured to control the passage of the first 306, respectively second 506, shift system of the guide position to the release position when the first, respectively second 410, handle is operated from the locking position to the unlocking position and Conversely. The first handle 210 here takes the form of a trigger 212 movable in translation in a plane perpendicular to the plane of the first rail 102a and guided by slides provided for this purpose in the frame 202. The second handle 410 takes the form of a rotary knob 412 rotatable about an axis perpendicular to the plane of the second rail 102b. The first transmission system 214 takes the form of a cable connecting the trigger 212 to said first shift system 306.
    [0041] The second transmission system 514 takes the form of a shaft (in dashed lines in FIG.
    [0042] 4A) integral, on the one hand, the rotary knob 412, and secondly, the second shift system 506. The shaft 514 is rotatable about its axis shown in Figs.
    [0043] 5A-B and said transmission axis 514a, which is perpendicular to the plane of the second rail 102b.
    [0044] In the embodiment of the invention as shown in Figs.
    [0045] 3A-B, the first shift system 306 is composed of two similar assemblies each of which comprise: an actuator 308 with a rod 310, for example a pneumatic jack, a shift arm 307 having a first end connected to the cable 214 20 and on which the actuator 308 is rotatably mounted, and a second end rotatably mounted on the frame 202, - a first arm 312 rotatably mounted on the frame 202 and articulated on the rod 310, - a second arm 314 whose one end is articulated on the first arm 312, and - a third arm 316 rotatably mounted on the frame 202 and carrying the grooved wheel 304c, and wherein the other end of the second arm 314 is mounted articulated on the third arm 316. When the actuator 308 is activated, for example under air pressure for a pneumatic cylinder, the position of the rod 310 is locked, which forces the wheel to throat 304c in guiding position against the rail 102a. When the actuator 308 is not activated, the position of the rod 310 is then loose, and actuation of the trigger 212 will pull the cable 214 which rotates the shift arm 307 and therefore the actuator 308 and its rod 310 as well as the arms 312, 314 and 316 so as to place the grooved wheel 304c in the release position as shown in FIG.
    [0046] 3B. Conversely, when the trigger 212 is released, a return means, of the torsion spring type, brings said trigger 212 back to its initial position. The return of the trigger 212 to its initial position causes the shift arm 307 to return to its initial position (FIG.
    [0047] 3A) where activation of the actuator 308 again locks the grooved wheel 304c in the guiding position. The routing of the cable 214 of the trigger 212 to the actuator 308 is performed using a series of pulleys 318. In the embodiment of the invention as shown in Figs.
    [0048] 5A-B, there are two movable 504c-d threshing wheels and the second offset 506 has a plane of symmetry (represented by the line 5 in FIG.
    [0049] 5A) which is the median plane between the two grooved wheels 504c-d which is perpendicular to the longitudinal direction of the second rail 102b. The second shift system 506 comprises: - a first hub 516c rotatable on the frame 402, the first hub 516c is fixed to the shaft 514 constituting the second transmission system 514 and the axis of rotation is offset relative to at its center and coincident with the transmission axis 514a, the grooved wheel 504c being rotatably mounted on the first hub 516c, 20 - a second hub 516d which is symmetrical with the first hub 516c with respect to the plane of symmetry 5, the second hub 516d is rotatable on the frame 402 and the axis of rotation is offset from its center, the grooved wheel 504d being rotatably mounted on the second hub 516d, - a fixed shaft 520 of which axis is symmetrical with the transmission axis 514a with respect to the plane of symmetry 5 and about which the second hub 516d is rotatably mounted, and - a rod 518 whose first end is rotatably mounted on the first hub 516c about an axis parallel to the transmission axis 514a, and whose second end is rotatably mounted on the second hub 516d about 30 of an axis parallel to the transmission axis 514a. The rotation of the rotary knob 412 will cause the rotation of the shaft 514 about its transmission axis 514a and the rotation of the first hub 516c and the retraction of the grooved wheel 504c, and at the same time the movement of the connecting rod 518 will cause rotation of the second hub 516d around the fixed shaft 520 and 3033273 13 the retraction of the grooved wheel 504d. Rotating the rotary knob 412 in the opposite direction will reset the 504c-d grooved wheels to their original positions. When the motor of the drive system 204 receives no activation command or is not powered electrically, it does not rotate thus ensuring the translation blocking of the driving slide 104 by the fact that a tooth of the toothed wheel 320 is inserted into a slot 216. To lock the driven slide 106 when the assembly bar 108 is not in place, the second rail 102b has slots 416 and the driven slide 106 has a tooth 462 and a system 460 which is configured to provide, when the assembly bar 108 is released from said driven slide 106, the insertion of the tooth 462 in a slot 416 and thus the locking in translation of the driven slide 106, and ensure, when the assembly bar 108 is fixed to said driven slide 106 or when a technician activates it voluntarily, the extraction of the tooth 462 from the slot 416 and thus the freedom of translation displacement of the driven slide 106. n particular embodiment of the security system 460 will be explained from Figs.
    [0050] 4A and 4C. The tooth 462 is mounted to move in translation on the frame 402, and more particularly under the bottom 450 in a direction perpendicular to the plane of the second rail 102b.
    [0051] The security system 460 comprises a safety shaft 468 rotatably mounted on the chassis 402 of the driven slide 106 about an axis locally parallel to the plane of the second rail 102b and a lever 464 fixed to the safety shaft 468. The lever 464 has a first end protruding from the bottom 450 of the driven slide 106 and a second end on which the tooth 462 is hinged, so when the tie bar 108 is in place, it presses on the first end, causing the lever 464 to tilt and the second end and the tooth 464 to lift out of the slot 416. To ensure automatic return of the tooth 464 in a slot 416 during the removal of the assembly bar 108, the security system 460 comprises a return means such as a spring, which forces the lever 464 in the position where the first end protrudes from the bottom 450 of the neck 106. To allow a technician to move the driven slide 106 even in the absence of the tie rod 108, the security system 460 has a safety handle 466 which is attached to the safety shaft 468. Thus, a rotation of the safety handle 466 causes the rotation of the safety shaft 468 and thus the tilting of the lever 464 and the lifting of the tooth 462. On each slide 104, 106, the assembly bar 108 is supported, on the one hand, against a face of the frame 202, 402 of said slide 104, 106 which is parallel to the plane of the rail 102a-b corresponding to said slide 104, 106, and, secondly, against a face of the frame 202, 402 of said slider 104, 106 which is perpendicular to the longitudinal direction of the rail 102a-b corresponding to said slider 104, 106.
