In the figure: the anti-skidding mechanism comprises a rotary table 1, anti-skidding ribs 2, a threaded rod 3, a threaded sleeve 4, a bottom plate 5, a bearing 6, a hinged rod 7, an abutting block 8, anti-skidding teeth 9, a fixing hole 10, a sliding groove 11, a limiting block 12, a sliding block 13 and a limiting groove 14.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-4, a clamping device for bearing ring processing comprises a bottom plate 5, a bearing 6 is fixedly connected to the middle position of the bottom plate 5, a threaded rod 3 is fixedly connected to the inner axial surface of the bearing 6, a rotary table 1 is fixedly connected to the upper end of the threaded rod 3, a threaded sleeve 4 is in threaded connection with the threaded rod 3, hinge rods 7 are hinged to two sides of the threaded sleeve 4, a butt block 8 is hinged to the lower end of the hinge rod 7, a sliding block 13 is fixedly connected to the lower end of the butt block 8, a sliding groove 11 is formed in the bottom plate 5, the sliding block 13 is slidably arranged in the sliding groove 11, a limiting mechanism is arranged on the inner wall of the sliding groove 11, the bearing ring is arranged on the outer side of the threaded rod 3, the threaded rod 3 is driven to rotate by rotating the rotary table 1, so as to adjust the position of the threaded sleeve 4 on the threaded rod 3, thereby adjusting the position, thereby fix the inner wall of bearing ring to polish the outer wall of bearing ring.

Example 2

Referring to fig. 4, as another preferred embodiment of the present invention, the difference with embodiment 1 lies in that the limiting mechanism includes a limiting groove 14 provided on the inner wall of the two sides of the sliding groove 11, a limiting block 12 is fixedly connected to the two ends of the sliding block 13, the limiting block 12 is slidably disposed in the limiting groove 14, and the limiting block 13 is acted by the limiting groove 14 through the cooperation of the limiting block 12 and the limiting groove 12, so that the sliding block 13 is always located in the sliding groove 11.
