[0002] Bearing rings are an important part of bearings, and their quality directly affects the precision, service life and performance of bearings. The manufacturing process of bearing rings is complex and requires high precision. Generally, it goes through multiple steps such as forging, heat treatment, turning, grinding and marking.

[0003] When the bearing ring is being polished, it needs to be fixed by a clamp. During the use of the existing bearing ring polishing clamp, the staff needs to manually fix the bearing ring, which is cumbersome to operate. When the other side of the bearing ring needs to be polished, the staff needs to disassemble and reinstall the bearing ring. This process takes a lot of time, resulting in a decrease in the polishing efficiency of the bearing ring. Therefore, a flip clamp for polishing the bearing ring is proposed. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a flipping fixture for grinding bearing rings. By arranging components such as a bidirectional lead screw, a motor, a worm and a turbine, an efficient and stable automatic control system is constructed. During the grinding process, the staff only needs to place the bearing ring on the fixture. Driven by the motor, the bidirectional lead screw can quickly and accurately fix the bearing ring. When the bearing ring needs to be flipped to grind the other side thereof, the synergistic effect of the worm and the turbine makes the flipping process simple and quick, and there is no need for the staff to manually disassemble and reinstall it.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
