One end of the push rod 122 can extend out of the mounting seat 121, and the end of the push rod 122 located away from the handle 123 is fixed with a mounting block 1221 by bolts, and a toggle rod is fixed to the bottom of the mounting block 1221, and the axial direction of the toggle rod is arranged vertically; an adjustment groove 51 for sliding connection of the toggle rod is provided at the top of the connecting rod bracket 5, and the length direction of the adjustment groove 51 is arranged parallel to the sliding direction of the slider 41. A toggle groove (not shown in the figure) for plugging the toggle rod is provided at the top of the connecting rod 71.

[0031] Reference Figure 2 and Figure 3, the connecting rod bracket 5 is provided with a through groove at the installation jaw 6. The jaw 6 is provided with a push inclined groove 61 for sliding connection of the push block 7. Correspondingly, the push block 7 is provided with guide surfaces 72 on both sides close to the jaw 6 for abutting against the push inclined groove 61. In addition, a connecting piece is provided between the two jaws 6 for limiting the sliding distance of the push block 7. The connecting piece is a reset spring 13, and there are two reset springs, which are respectively located at the upper and lower parts of the jaw 6. Vertical rods are fixed to the top and bottom of the jaw 6, respectively, for connecting the two ends of the reset spring 13. During installation, the two ends of the reset spring are not on the same jaw 6.

[0032] Reference Figure 2 and Figure 3 In addition, in order to further ensure the fixing effect of the clamping jaw 6 on the sleeve, the side of the clamping jaw 6 facing the outside is designed to be an arc surface, and the clamping jaw 6 is installed at the arc surface. A fixing groove for the pin 62 to be inserted is opened on the inner wall of the sleeve (not shown in the figure).

[0033] The implementation principle of a shaft sleeve removal device in the embodiment of the present application is:

[0034] When disassembly is required, first place the product to be disassembled in the positioning groove 31, flip the clamping block 81 and rotate the butterfly bolt 82 until the product is fixed on the positioning block 3; then the stepper motor 105 drives to control the adapter plate 4 and the connecting rod bracket 5 and the two clamping claws 6 and other components to move toward the product until the clamping claws 6 are inserted into the inner cavity of the bearing; then press the handle 123 on the quick clamp 12 downward, so that the push rod 122 drives the toggle rod to drive the connecting rod 71 to move toward the bearing, so that the push block 7 pushes the two clamping claws 6 to open outward, thereby clamping the sleeve, and the pin 62 is inserted into the fixing groove; then the stepper motor 105 controls to move the various components on the adapter plate 4 away from the product, and pulls the sleeve out of the product, so that the sleeve can be disassembled, thereby improving the problem of easy damage to the sleeve and the sleeve hole during disassembly.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
