By rotating the second pressure cover screw 11, the second pressure cover screw 11 is gradually tightened against the step shaft 12, and the bearing 13 on the step shaft 12 is gradually pulled out together with the entire tooling. The disassembly tooling of the bearing 13 on the step shaft 12 can realize the rapid disassembly of the bearing 13 on the step shaft 12 and reduce the risk of damage to the step shaft 12.

[0037] like Figure 2 As shown, in this embodiment, the upper clamping ring 1 and the lower clamping ring 2 are both Ω-shaped, the middle parts of the upper clamping ring 1 and the lower clamping ring 2 are both semicircular, the upper clamping ring 1 and the lower clamping ring 2 are connected to form a circle by the clamping ring screw 5, and the diameter of the circle formed by the upper clamping ring 1 and the lower clamping ring 2 is equal to the outer diameter of the bearing 13.

[0038] The upper clamping ring 1 also includes a clamping ring hole 3, which is opened at both ends of the upper clamping ring 1. The lower clamping ring 2 also includes a clamping ring thread hole 4, which is opened at both ends of the lower clamping ring 2. The clamping member is a clamping ring screw 5, which passes through the clamping ring hole 3 and is fixed to the clamping ring thread hole 4 to connect the upper clamping ring 1 and the lower clamping ring 2. Specifically, in this embodiment, the inner walls of the upper clamping ring 1 and the lower clamping ring 2 are both frosted, which can increase the friction between the bearing 13 and the upper clamping ring 1 and the lower clamping ring 2.

[0039] The connection assembly includes a first gland hole 8, which is provided on the gland 6, and two first gland holes 8 are provided. Specifically, in this embodiment, the gland 6 is circular.

The diameter of the first gland hole 8 is larger than the diameter of the first gland screw 7.

[0042] Working principle:

[0043] In order to increase the force-bearing area of ​​the bearing 13, an upper clamping ring 1 and a lower clamping ring 2 are designed. The upper clamping ring 1 and the lower clamping ring 2 have similar structures and are symmetrically distributed. The diameter of the circle formed by the middle of the upper clamping ring 1 and the lower clamping ring 2 is equal to the outer diameter of the disassembled bearing 13. The two holes on the upper clamping ring 1 are clamping ring holes 3, which are through holes, and the two holes on the lower clamping ring 2 are clamping ring thread holes 4. The clamping ring screw 5 is connected with the clamping ring thread hole 4 through the clamping ring hole 3 to achieve the clamping of the disassembled bearing 13. There is a first gland thread hole 9 in the middle of the upper clamping ring 1 and the lower clamping ring 2 for connection with the gland 6.

[0044] In order to pull out the bearing 13, a gland 6 is designed, and the first gland screw 7 connects the gland 6 with the clamping assembly through the first gland hole 8. The first gland hole 8 is a long slot hole designed symmetrically along the diameter direction to accommodate bearings 13 of different specifications. A second gland thread hole 10 is processed at the center position of the gland 6, and the second gland screw 11 cooperates with the second gland thread hole 10. By rotating the second gland screw 11, the second gland screw 11 gradually presses against the step shaft 12, and the bearing 13 on the step shaft 12 together with the entire tooling will be gradually pulled out.

[0045] Working steps:

[0046] ①Clamp the non-working surface of the stepped shaft 12 on the vise;

[0047] ② Clamp the upper clamping ring 1 and the lower clamping ring 2 onto the disassembled bearing 13 through the clamping ring screws 5;

[0048] ③ Fasten the gland 6 to the upper clamping ring 1 and the lower clamping ring 2 through the first gland screw 7. Figure 3 As shown;

[0049] ④ Use a wrench to turn the second gland screw 11 until the bearing 13 is removed;

[0050] ⑤ Loosen the clamping ring screw 5 between the upper clamping ring 1 and the lower clamping ring 2, and remove the bearing 13 from the tooling.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
