Description

Technical Field

[0001] The utility model relates to the field of hub bearing processing, in particular to a turning fixture for hub bearing processing. Background Technique

[0002] Hub bearings are components applied at the vehicle axles of automobiles to bear weight and provide precise guidance for the rotation of the hubs. They bear both axial loads and radial loads and are important components for the load bearing and rotation of automobiles. The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings as a whole, with advantages such as good assembly performance, omission of clearance adjustment, light weight, compact structure, large load capacity, pre-installation of grease for sealed bearings, omission of external hub seals, and freedom from maintenance. It has been widely used in sedans and has a tendency to be gradually expanded in application in heavy-duty trucks.

[0003] During the processing of hub bearings, turning treatment needs to be carried out on the outside of the bearings. When turning, a turning fixture is required to fix the hub bearings. However, the existing turning fixtures clamp one end of the bearings. When turning the outer ring of the bearings, the clamped end of the bearings is not convenient for turning, and it is necessary to adjust the end face of the bearings for re-turning, which affects the processing efficiency. Therefore, we propose a turning fixture for hub bearing processing to solve the above problems. Content of the Utility Model
