  First, the configuration of the setting jig 21 will be described in detail with reference to FIGS.

  As shown in FIGS. 1 to 3, the setting jig 21 temporarily assembles a disk-shaped upper sheet (second disk member) 10, a bearing 11, and an insulator (first disk member) 12 in advance. The setting jig 21 includes a base plate (base member) 22. An opening 23 is formed in a keyhole shape in the base plate 22, and a fitting portion 24 is formed in the opening 23. A fixing claw 25 is fixed to the lower surface of one end of the base plate 22, and a support plate 26 is fixed to the upper surface of the other end, and the base end of the guide block 27 is supported on the lower surface of the support plate 26. Has been.

  The upper surface 27a of the guide block 27 is formed substantially horizontally, and the upper surface 27a is inclined downward from the proximal end to the distal end of the guide block 27, that is, inclined so that the groove depth becomes deeper. An upper inclined groove 28 extending in the radial direction of the upper sheet 10 is formed. On the other hand, the lower surface 27b of the guide block 27 is formed so as to be inclined downward from the proximal end to the distal end of the guide block 27, and the lower surface 27b is inclined downward from the proximal end to the distal end, and A lower inclined groove 29 extending in the radial direction of the upper sheet 10 is formed. The inclined surfaces 28a and 29a of the inclined grooves 28 and 29 are inclined at substantially the same inclination angle, and a through hole 30 is formed in the inclined grooves 28a and 29a so as to penetrate the inclined surfaces. .

  Further, an upper inclined block 31 is provided on the upper surface 27a, and a sliding surface 31a which is a lower surface of the upper inclined block 31 has substantially the same inclination angle as the inclined surface 28a. That is, the upper inclined block 31 is movably supported in the upper inclined groove 28. On the other hand, a lower inclined block 32 is provided on the lower surface 27b, and the lower inclined block 32 is formed with a fitting portion 32a and sliding surfaces 32b formed on both sides thereof. The fitting portion 32a is fitted into the lower inclined groove 29, and the sliding surface 32b has substantially the same inclination angle as the lower surface 27b.

  Further, a slide plate 33 is provided below the lower inclined block 32, and movable claws 34 are provided at both ends of the slide plate 33. The upper inclined block 31, the lower inclined block 32, and the slide plate 32 are fixed by a fixing pin 35 through a through hole 30, and a compression spring is provided between the head of the fixing pin 35 and the upper inclined block 31. 36 is interposed. That is, the inclined blocks 31 and 32 are pressed against the guide block 27 by the urging force of the compression spring 36.

  The guide block 27, the upper inclined block 31, the lower inclined block 32, etc. constitute movable claw moving means, while the fixed pin 35, the compression spring 36, etc. constitute urging means.

  Next, a method for setting the upper sheet 10, the bearing 11, and the insulator 12 to the setting jig 21 will be described with reference to FIGS.

  Here, the size of the strut assemblies 4a and 4b varies depending on the size of the vehicle 1, the size of the installation space, the size of the spring force, and the like. Thereby, the magnitude | size (length of a diameter) of the upper sheet | seat 10, the bearing 11, and the insulator 12 also becomes various. The setting jig 21 according to the present invention can correspond to these various sizes, and in this embodiment, two types of large and small workpieces (strut assemblies) will be described. In the setting method to the setting jig 21 described below, the large workpiece is indicated as an upper sheet 10B, a bearing 11B, and an insulator 12B, and the small workpiece is indicated as an upper sheet 10S, a bearing 11S, and an insulator 12S.

  First, when the upper seat 10B, the bearing 11B, and the insulator 12B are set, as shown in FIGS. 4 to 6, bolts (projections) 14 (three in the figure) for fixing to the vehicle body frame 2 are used. After mounting at a predetermined position of 12B from below, the upper seat 10B, the bearing 11B, and the insulator 12B are assembled so that the mounting holes 10b, 11b, and 12b coincide. In this assembled state, any one bolt 14 is fitted to the fitting portion 24, and the fixing claw 25 is the outer edge of the upper sheet 10B and the vicinity of the bolt 14 fitted to the fitting portion 24 (see FIG. 4) and 6). Next, while pressing the fixed pin 35 downward and releasing the urging force by the compression spring 36, the fixed pin 35 is moved to the proximal end side of the guide block 27, that is, the movable claw 34 is the outer edge of the upper sheet 10B. It is made to engage with the position (lower part in FIGS. 4 and 6) separated from the bolt 14 fitted to the fitting part 24. And the pressing force to the fixing pin 35 is cancelled | released, the movement of the movable nail | claw 34 is controlled, and engagement with the outer edge of the upper sheet | seat 10B is hold | maintained.

  Therefore, by setting the setting jig 21 as described above, the bolt 14 can be fitted into the fitting portion 24, and thus the circumferential rotation of the insulator 12B can be prevented. That is, the insulator 12B can be positioned in the circumferential direction. Further, since the fixed claw 25 and the movable claw 34 can be engaged with the outer edge of the upper sheet 10B, the upper sheet 10B can be positioned in the vertical direction. Thereby, since the insulator 12B is also pressed against the lower surface of the base plate 22, the insulator 12B can be positioned in the vertical direction. In the case of a bearing-equipped specification, the bearing 11B can be positioned by being sandwiched between the upper seat 10B and the insulator 12B. As a result, it can be set without causing misalignment, so that the assembly accuracy of the upper sheet 10B, the bearing 11B, and the insulator 12B can be improved.

  Further, when the upper seat 10S, the bearing 11S, and the insulator 12S are set, as shown in FIGS. 7 to 9, bolts 14 (three in the figure) for fixing to the vehicle body frame 2 are set at predetermined positions of the insulator 12S. Then, the upper seat 10S, the bearing 11S, and the insulator 12S are assembled so that the mounting holes 10s, 11s, and 12s are aligned. In this assembled state, any one bolt 14 is fitted to the fitting portion 24, and the fixing claw 25 is the outer edge of the upper sheet 10S and the vicinity of the bolt 14 fitted to the fitting portion 24 (see FIG. 7 and 9). Next, while pressing the fixed pin 35 downward and releasing the urging force by the compression spring 36, the fixed pin 35 is moved to the proximal end side of the guide block 27, that is, the movable claw 34 is the outer edge of the upper sheet 10S. It is made to engage with the position (lower part in FIG. 7, 9) separated from the volt | bolt 14 fitted by the fitting part 24. FIG. Then, the pressing force to the fixed pin 35 is released, the movement of the movable claw 34 is restricted, and the engagement with the outer edge of the upper sheet 10S is held.

  Therefore, the bolt 14 can be fitted to the fitting portion 24 by the above-described configuration, and thus the circumferential rotation of the insulator 12S can be prevented. That is, the insulator 12S can be positioned in the circumferential direction. Further, since the fixed claw 25 and the movable claw 34 can be engaged with the outer edge of the upper sheet 10S, the upper sheet 10S can be positioned in the vertical direction. Thereby, since the insulator 12S is also pressed against the lower surface of the base plate 22, the insulator 12S can be positioned in the vertical direction. In the case of a bearing-equipped specification, the bearing 11 can be positioned by being sandwiched between the upper seat 10S and the insulator 12S. As a result, it can be set without causing misalignment, so that the assembly accuracy of the upper sheet 10S, the bearing 11S, and the insulator 12S can be improved.

  And by providing the movable nail | claw 34 supported so that a movement is possible, it can respond also to the upper sheet | seat 10, the bearing 11, and the insulator 12 of all sizes. Further, since the urging force of the compression spring 36 is used to move and stop the movable claw 34, the movable claw 34 can be reliably engaged and the workability of the engagement can be improved.

In addition, about the removal operation | movement of the set jig 21 attached to the strut assembly 4b, since it is the same operation | movement, description is abbreviate | omitted.

  The upper sheet 10 </ b> B, the bearing 11 </ b> B, and the insulator 12 </ b> B for a large work shown in FIGS. 4 to 6 are temporarily assembled using the setting jig 21. Alternatively, the upper sheet 10 </ b> S, the bearing 11 </ b> S, and the insulator 12 </ b> S for a small work shown in FIGS. 7 to 9 are temporarily assembled using the setting jig 21. Along with the temporary assembly comprising the upper seat 10 (10B, 10S), the bearing 11 (11B, 11S) and the insulator 12 (11B, 11S), the strut body 5, the piston rod 6, the lower seat 7, the coil spring 8, etc. The strut assemblies 4a and 4b are simultaneously assembled using the strut assembly device 41.

  As shown in FIGS. 10 and 11, the assembled strut assemblies 4 a and 4 b are transported below the set jig removing device 51 by the transport device 44.

The tilt amount of the tilt plate 69 is set so that the movable claw 34 is disposed at a position above the upper seat 10 according to the stroke amount of the tilt cylinder 54.

  Next, as shown in FIGS. 27 and 28 (setting jig sliding operation and setting jig removing operation), the sliding cylinder 62 is shortened and the inclined plate 69 is slid while being inclined. Thereby, the fixed claw 25 comes off from the outer edge of the upper sheet 10. That is, the base plate clamping chuck 73 clamps the base plate 22, and the movable claw clamping chuck 84 remains in a state of clamping the movable claw 34, while the fixed claw 25 and the movable claw 34 are detached from the upper sheet 10. That is, the setting jig 21 is removed from the strut assembly 4a.

  Next, as shown in FIGS. 29 and 30 (ascending operation), the strut assembly 4a is brought together with the base plate clamp chuck 73, the stopper 75, the movable claw inclination preventing hook 82, and the movable claw clamp chuck 84 by shortening the elevating cylinder 55. At the same time as the setting jig 21 removed from the upper side rises, the inclined plate 69 is returned to a substantially horizontal state. At this time, the inclined plate 69 comes into contact with the locking pin 71 and is always maintained in a substantially horizontal state.

  The strut assembly 4 a from which the setting jig 21 has been removed is discharged from the strut assembly device 41 by the transport device 44. At the same time, the set jig conveyance path 45 extends to the lower side of the set jig 21 clamped. Thereafter, the movable portion 72a of the air chuck 72 is activated, and the base plate clamping chuck 73 is opened and released from the base plate 22, while the movable portion 83a of the air chuck 83 is activated and the movable claw clamping chuck 84 is opened and movable. The nail 34 is released. As a result, the setting jig 21 falls on the setting jig conveyance path 45 and is collected in the collection box 46. Furthermore, the strut assembly 4a is produced by repeating the above-described operation.

  Accordingly, the stopper 75 is provided by configuring the setting jig removing device 51 as described above, so that the base plate clamping chuck 73, the movable claw inclination preventing hook 82, and the movable claw clamping chuck 84 are brought to a predetermined height. The held setting jig 21 can always be lowered to a certain height, and the removal operation can be performed smoothly. Moreover, the setting jig 21 can be tilted by applying the brake 55b to stop the operation of the lifting cylinder 55 and shortening the tilting cylinder 54.

  Further, by providing the switching cylinder 79 and the movable claw removal cylinder, the movable claw clamping chuck 84 can clamp the movable claw 34 corresponding to the upper sheet 10, the bearing 11 and the insulator 12 of any size. The movable claw inclination preventing hook 82 can press the fixed pin 35. Furthermore, the movable claw 34 can be easily detached from the outer edge of the upper sheet 10 by providing the tilting cylinder 54, while the fixed claw 25 is easily removed from the outer edge of the upper sheet 10 by providing the sliding cylinder 62. be able to.

  Since the removed set jig 21 is collected by the collection box 46 via the set jig conveyance path 45, the set jig 21 can be quickly reused, and productivity can be improved.
