Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts polishing, in particular to a polishing device for automobile parts production. Background Art

[0002] The wheel hub is a vital component in the vehicle's driving system. Serving as the supporting structure for the inner profile of the tire, it is connected to the wheel core through columns and directly installed on the vehicle axle. To ensure the strength and stability of the wheel hub while meeting the installation and rotation requirements of the wheel, the wheel hub surface is usually designed with a certain arc or curved shape. The arc design helps to distribute the force acting on the wheel more evenly on the wheel hub, reduce stress concentration, and improve the wheel hub's load-bearing capacity and service life.

[0003] During the production process, the wheel hub will first undergo preliminary forming processes such as casting or forging. After these processes are completed, some burrs, uneven or rough areas may be left on the surface of the wheel hub. In order to make the wheel hub surface smoother and flatter and meet the requirements of subsequent processing and use, it is usually polished after casting or forging.

[0004] When polishing the hub surface, the existing polishing device cannot fit the hub surface as a whole due to the arc / curved hub surface and the small size of the polishing device. Therefore, the position of the polishing device (such as the polishing wheel / coarse grinding block) on the hub surface needs to be continuously adjusted, which can easily lead to uneven polishing and reduce the quality of the hub at the factory. Utility Model Content

It is necessary to continuously adjust the position of the polishing device (such as the polishing wheel / coarse grinding block) on the wheel hub surface, which easily leads to uneven polishing and thus reduces the factory quality of the wheel hub.
