Description

Technical Field

[0001] The utility model relates to the technical field of grinding fixtures, in particular to a grinding fixture. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. They can support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during the transmission process. During the bearing processing, the surface of the bearing needs to be polished. The bearing polishing machine is a device that polishes the inner ring raceway or outer ring raceway of the bearing during the bearing processing. The bearing needs to be fixed before polishing, so a polishing fixture is needed.

[0003] At present, when the bearing grinding fixtures on the market are used, when grinding the inner ring raceway of the bearing, the inner ring needs to be fixed from the inside of the inner ring, and when grinding the outer ring raceway, the outer ring needs to be fixed from the outside of the outer ring. The existing fixtures can only fix the inner ring or the outer ring, and the applicability is poor. The related technology is to provide a stepped fixture, which can fix the inner ring or the outer ring of the bearing. However, in actual use, the position where the fixture contacts the bearing cannot contact the grinding mechanism, and the bearing needs to be disassembled and reinstalled to grind the overlapping parts, resulting in low efficiency, certain limitations, and inconvenience in use.
