The outer wall of the first polishing roller 11 is fixedly connected to a first telescopic rod 12 that is fixedly connected to the outer wall of the rotating shaft 5. The outer wall of the first lifting block 8 is rotatably connected to a second pulling rod 13. One end of the second pulling rod 13 is rotatably connected to a second polishing roller 14 that is in contact with the outer wall of the bearing body 2. The outer wall of the second polishing roller 14 is fixedly connected to a second telescopic rod 15 that is fixedly connected to the outer wall of the first polishing roller 11.
[0024] Among them, such as Figure 3 As shown, the lengths of the first polishing roller 11 and the second polishing roller 14 are both adapted to the thickness of the bearing body 2, and the central axes of the first polishing roller 11 and the second polishing roller 14 are aligned with each other. The first lifting block 8 forms a lifting structure with the rotating shaft 5 through the threaded rod 6, which facilitates the rotation of the threaded rod 6 and drives the first lifting block 8 to move up and down along the outer wall of the rotating shaft 5, thereby effectively driving the first pulling rod 10 to rotate.
[0025] Among them, such as Figure 3As shown, the first pull rod 10 and the second pull rod 13 are each provided with four groups, and the positions of the four groups of the first pull rod 10 and the second pull rod 13 are distributed in a ring shape on the outer wall of the rotating shaft 5. The first pull rod 10 forms a rotating structure with the second lifting block 9 and the first polishing roller 11, which is conducive to the sliding of the second lifting block 9 through the connection of the first polishing roller 11, driving the effective rotation of the first pull rod 10, and playing a role in effectively adjusting and fitting the size of the inner wall of the bearing.
[0026] As shown in the figure, Figure 3 The sliding directions of the first lifting block 8 and the second lifting block 9 are the same, and the spacing between the first polishing roller 11 and the second polishing roller 14 is adapted to the inner and outer spacing of the bearing body 2.
