The divided piece 12D is provided with a through hole 12F through which the shaft portion 16A of the fastening bolt 16 is inserted. The threaded portion is not provided in the through hole 12F. In a state in which the screw portion 16B of the fastening bolt 16 is not screwed into the divided pieces 12C, the inner diameter of the hole 12A is set to be slightly larger than the outer diameter of the slide portion 14 (the outer peripheral surface 14B). That is, by forming a gap between the inner peripheral surface of the hole 12A and the outer peripheral surface 14B of the slide portion 14, the slide portion 14 can slide the hole 12A of the support column 12 in the axial direction (slide) Possible).

  In this embodiment, the shaft portion 16A of the fastening bolt 16 is inserted into the through hole 12F from one of the divided pieces 12D, and the screw portion 16B of the shaft portion 16A is screwed into the screw hole 12E of the other divided piece 12C. . By tightening the fastening bolt 16, the distance between the slit 12B between the pair of divided pieces 12C and 12D is reduced (the width of the slit 12B is reduced), and the slide portion 14 is fixed to the hole 12A of the support 12. ing. In addition, by loosening the fastening bolt 16, the distance between the slit 12B between the pair of divided pieces 12C and 12D is increased (the width of the slit 12B is increased), and the slide portion 14 is pivoted relative to the hole 12A of the support 12. It is possible to slide in the direction (see FIG. 3).

  As shown in FIG. 1A and FIG. 2, the position adjustment unit 18 includes a main body unit 20 having a male screw portion 20A as a second screw portion screwed to the female screw portion 14A of the slide portion 14 And a pusher 22 as a sliding member slidably supported inside the main body 20. The main body portion 20 has a substantially cylindrical shape, and a smooth inner circumferential surface 20B is provided on the inner circumferential side. The pusher 22 has a substantially cylindrical shaft portion 22A slidably supported (inserted) on the inner circumferential surface 20B of the main body portion 20, and an abutment plate 22B as a contact portion attached to the tip of the shaft portion 22A. And have. The outer diameter of the shaft portion 22A is set to be slightly smaller than the inner diameter of the main body portion 20 (inner peripheral surface 20B), and a gap is formed between the outer peripheral surface of the shaft portion 22A and the inner peripheral surface 20B of the main body portion 20. As a result, the shaft 22A can slide inside the main body 20.

  The abutment plate 22B is a substantially circular plate disposed in a direction orthogonal to the axial direction of the shaft portion 22A. The shape of the abutment plate 22B is not limited to a substantially circular shape, and can be changed.

  The end 22C of the abutment plate 22B opposite to the shaft 22A is in contact with the end of the joint 50 opposite to the clamp 54 (the end 52B opposite to the core 52A in the axial direction of the joint body 52). It is considered to be a contact part. When the end 52B of the joint 50 contacts (abuts on) the surface 22C of the abutment plate 22B, the axial caulking position of the joint 50 is positioned by the abutment plate 22B.

  At the end of the main body 20 opposite to the pusher 22 in the axial direction, a wall 20C is provided that closes the internal space of the main body 20 (the inner side of the inner circumferential surface 20B). Inside the main body portion 20, a coil spring 24 as an elastic body is provided between the end face of the shaft portion 22A of the pusher 22 and the wall portion 20C. When the joint 50 is crimped, the coil spring 24 allows sliding of the surface 22C of the abutment plate 22B to the main body 20 side. The position adjusting portion 18 may be provided with a stopper for holding the pusher 22 at a predetermined position in the axial direction of the main body portion 20 when the crimped position in the axial direction of the joint 50 is positioned.

  In the position adjustment unit 18, the male screw 20 A engaged with the female screw 14 A of the slide 14 is rotated by the rotation of the main body 20, so that the main body 20 moves in the axial direction with respect to the slide 14. It is supposed to In the present embodiment, the thread pitch of the male screw portion 20A is set to about 1 mm. Thus, by rotating the main body portion 20 about a half turn, the main body portion 20 is moved about 0.5 mm in the axial direction with respect to the slide portion 14.

  In the position adjustment unit 18, the position of the surface 22C of the abutment plate 22B with respect to the caulking die 4 is obtained by moving the main body portion 20 axially with respect to the slide portion 14 by rotation of the male screw portion 20A of the main body portion 20. Is adjusted (see FIG. 1 (A)). As described above, since the thread pitch of the male screw portion 20A is set to about 1 mm, the rotation of the male screw portion 20A of the main body portion 20 causes the face 22C of the abutment plate 22B to the caulking die 4 to be rotated. The position is finely adjusted with an accuracy of about 1 mm or less. Further, for example, when changing the type of the joint 50 or the like every time the joint 50 is caulked, the position of the surface 22C of the abutment plate 22B with respect to the caulking die 4 using the caulking position adjusting jig 10 Can be fine-tuned.

  Next, the operation of the caulking position adjustment jig 10 and the caulking device 2 and the caulking position adjustment method will be described.

  When adjusting the caulking position of the joint 50 (see FIG. 1) in the axial direction with the caulking position adjusting jig 10, as shown in FIGS. Loosen the fastening bolt 16. Thus, the slide portion 14 can slide in the axial direction with respect to the column 12 (slidable), and the amount of axial movement of the slide portion 14 with respect to the column 12 can be increased.

  In the present embodiment, the slide portion 14 is slid (slided) in the left direction indicated by arrow A in FIG. 3A with respect to the support 12, for example, so that the surface 22C of the abutment plate 22B is in the crimped position. Move to the corresponding axial rough position (approximate position). Since the slide portion 14 is configured to slide relative to the column 12, the amount of movement of the slide portion 14 relative to the column 12 is large, and the slide portion 14 is immediately moved relative to the column 12 to, for example, about 20 mm. Can. Thus, for example, as shown in FIGS. 3A and 4A, the surface 22C of the abutment plate 22B is moved from the axial position 30A to the position 30B. In this state, as shown in FIGS. 4A and 4B, the fastening bolt 16 is tightened to fix the slide portion 14 to the support 12.

  Thereafter, as shown in FIGS. 4A and 5A, the axial position 30B of the surface 22C of the abutment plate 22B is finely adjusted by rotating the main body 20 of the position adjustment unit 18. . More specifically, by rotating the main body portion 20 in the direction of the arrow B, the male screw portion 20A screwed to the female screw portion 14A of the slide portion 14 is rotated, and the main body portion 20 is rotated relative to the slide portion 14. Move in the axial direction. Thereby, the main body portion 20 is moved relative to the slide portion 14 in the left direction indicated by arrow C in FIG. 5A, for example, and the surface 22C of the abutment plate 22B is moved to the axial position 30C. Thus, the surface 22C of the abutment plate 22B can be moved to the axial position 30C corresponding to the crimped position of the joint 50.

  In this state, as shown in FIG. 5A, the joint 50 is positioned by bringing the end 52B of the joint body 52 of the joint 50 into contact (abutment) with the surface 22C of the abutment plate 22B. Thereby, with respect to the caulking die 4 of the caulking device 2, the caulking position of the joint 50 in the axial direction can be adjusted with high accuracy.

  Thereafter, as shown in FIG. 6A, the diameter of the plurality of clamping dies 4 is reduced by driving means (not shown), and the clamping metal fittings 54 of the joint 50 are crimped from the outer periphery by the plurality of clamping dies 4. The joint 50 is fixed (connected) to the hose 60. In the position adjustment unit 18, the shaft 22A of the pusher 22 is slidably supported inside the main body 20, and the coil spring 24 is disposed between the end face of the shaft 22A of the pusher 22 and the wall 20C. ing. When caulking the caulking metal fitting 54 is caulked by the caulking die 4, an axial extension occurs in the caulking metal fitting 54, but the coil spring 24 is compressed so that the arrow D direction of the surface 22C of the abutment plate 22B. Sliding to (the main body 20 side) is allowed. That is, the compression of the coil spring 24 causes the surface 22C of the abutment plate 22B to move to the position 30D in the direction of arrow D, thereby absorbing the axial elongation at the time of crimping of the clamp 54. it can.

  Although illustration is omitted, as the caulking position adjustment jig of the first comparative example, for example, the slide portion is supported slidably on the support column 12 in the axial direction, and the pusher 22 provided with the abutment plate 22B is slid on the slide portion A configuration is provided that can be moved. That is, the main body unit 20 of the position adjustment unit 18 is not provided. In this configuration, the slide portion can be moved in the axial direction with respect to the column 12 by loosening the fastening bolt 16, but the amount of movement of the slide portion with respect to the column 12 is large, and the position of the slide portion is finely adjusted. Is difficult. For this reason, it is difficult to finely adjust the position of the abutment plate 22B corresponding to the crimped position in the axial direction of the joint.

  Further, although not shown, as a caulking position adjustment jig of the second comparative example, for example, a female screw portion is provided on a post, and a male screw portion 20A (long screw) of the main body portion 20 is screwed on this female screw portion. A configuration to match is conceivable. That is, the slide unit 14 is not provided. In this configuration, by rotating the male screw 20A of the main body 20, the main body 20 can be moved in the axial direction with respect to the female screw of the support, and the position of the main body 20 can be finely adjusted. However, since it is necessary to manually rotate the male screw 20A of the main body 20, there is a problem that it takes time to position the main body 20 with respect to the support.

  On the other hand, in the caulking position adjustment jig 10 of the present embodiment, the slide portion 14 is largely slid (slided) in the axial direction with respect to the column 12 by loosening the fastening bolt 16. Move 14 to a rough axial position. Then, the main body 20 is rotated relative to the slide 14 by rotating the main body 20 (male screw 20A) of the position adjustment unit 18 in a state where the fastening bolt 16 is tightened and the slide 14 is fixed to the support 12. The position is moved in the axial direction to finely adjust the position of the abutment plate 22B. Therefore, the caulking position of the joint 50 in the axial direction with respect to the caulking die 4 can be accurately adjusted, and the workability at the time of adjusting the caulking position can be improved by the caulking position adjusting jig 10. .
