Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring polishing, in particular to a bearing ring raceway polishing tool. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or more raceways. During the production process of the bearing ring, the ring needs to be polished to prevent the bearing ring raceway from being rough, generating noise, affecting the service life of the bearing ring, and causing serious impact on the accuracy of the bearing ring.

[0003] In the existing process of polishing the raceway of the bearing ring, a jet polisher is usually used for polishing. The staff wears gloves and holds the bearing ring so that the bearing ring is located below the jet port of the jet polisher for polishing. During the polishing process, the staff needs to manually rotate the bearing ring and polish it by feel. As a result, during the polishing process, due to factors such as the speed and shaking of the bearing ring, the polishing of the bearing ring is not uniform. Since the bearing ring is a precision component, the quality of polishing is affected, which directly leads to a reduction in the accuracy and service life of the bearing ring. In addition, the staff's hand-held polishing is more physically demanding, which leads to low efficiency in the actual operation process. Utility Model Content

During the polishing process, the operation of the driving motor drives the rotating shaft to rotate, so that the rotating shaft drives one of the rotating blocks to rotate. Due to the clamping connection to the bearing ring, the other rotating block rotates with it, thereby realizing the rotational polishing of the bearing ring, improving the polishing speed and quality of the bearing ring, ensuring the accuracy of the bearing ring, and extending its service life.
