[0002] The assembly of positioning pins or pin bolts is often involved in the disassembly and assembly of clutch equipment. The positioning pins or pin bolts are used with transition fit or small interference fit with the equipment. Therefore, it is very difficult to disassemble and assemble, especially when the space is limited and manual knocking is not possible. Even if there is enough space, knocking will bring certain impact and vibration, which can easily damage the mating surface and cause subsequent failure to use normally. Utility Model Content

[0003] The utility model aims to provide a clutch pin bolt disassembly and assembly device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Furthermore, a top plate is inserted at the end of the bolt, a non-slip layer is provided on the lower surface of the top plate, a hydraulic jack is provided at the lower end of the top plate, and a central axis of the top plate is on the same vertical line as a central axis of the bolt.

[0007] Furthermore, a pad is overlapped on the lower wall of the bracket, a avoidance hole is provided in the center of the pad, and a central axis of the avoidance hole is on the same vertical line as a central axis of the bolt.

[0008] Furthermore, the pads are provided in multiple groups of different models according to needs.

[0009] Furthermore, the pad is made of copper.

[0010] Furthermore, a “]”-shaped reinforcing rib is provided on the outer side of the bracket, and there are two reinforcing ribs, which are symmetrically arranged on the outer edge of the bracket.

[0011] Compared with the prior art, the clutch pin bolt disassembly and assembly device adopting the above technical solution has the following beneficial effects: the clutch pin bolt disassembly and assembly device of the utility model has a simple structure, is easy to use, is not sensitive to the disassembly and assembly space requirements, can disassemble and assemble the pin bolts in a small space, and the force is evenly applied during the disassembly and assembly process, and will not cause damage to the components.

[0017] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the embodiments are not intended to limit the present invention. All similar structures and similar variations of the present invention should be included in the protection scope of the present invention.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The clutch pin bolt disassembly and assembly device shown comprises a “]” shaped bracket 1, and a “]” shaped reinforcing rib 8 is arranged on the outer side of the bracket 1. The reinforcing rib 8 is two in number and symmetrically arranged on the outer edge of the bracket 1. The upper wall of the bracket 1 is provided with a bolt 4, and a threaded hole is provided on the upper wall of the bracket 1 corresponding to the bolt 4. The bolt 4 is screwed and fixed on the threaded hole of the bracket 1, and the screwing depth of the bolt 4 is adjusted by the thread; the end of the bolt 4 is plugged with a top plate 3, and a groove is provided on the top plate 3 corresponding to the bolt 4. The lower surface of the top plate 3 is provided with an anti-slip layer, and the lower end of the top plate 3 is a hydraulic jack 5. The head of the bolt 4 is inserted into the groove of the top plate 3, and the top plate 3 is pressed against the hydraulic jack 5 to provide a bearing surface for the hydraulic jack 5; the lower wall of the bracket 1 is provided with an avoidance space 6, and a pad 2 is overlapped on the lower wall of the bracket 1 to protect product parts. A avoidance hole 7 is provided in the center of the pad 2, and the central axis of the bolt 4 is in the same vertical line as the central axis of the avoidance space 6, the central axis of the top plate 3, and the central axis of the avoidance hole 7. The pad 2 is provided with multiple groups of different models according to needs; the pad 2 is made of copper. The pad 2 is pressed against the bottom surface of the bracket, and different pads can be selected according to the size of the pin bolt.

[0019] In actual use, first install the bolt 4 into the screw hole of the bracket 1, then insert the top plate 3 into the end of the bolt 4, and control the disassembly and assembly space by adjusting the screwing depth of the bolt; press the hydraulic jack 5 against the lower surface of the top plate 3, install the pad 2 on the lower wall of the bracket 1, and finally place the pin bolt vertically in the hole of the corresponding shaft, so that the centers of the top plate 3, the hydraulic jack 5 and the pin bolt are kept in the same straight line, and the hydraulic jack 5 can be used to press the pin bolt, and the pin bolt is slowly pressed into the pin hole of the matching shaft through the action of hydraulic pressure. When dismantling, use it in reverse and slowly withdraw the pin bolt from the pin hole.

[0020] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
