Technical Field
[0001] This utility model relates to the field of burnishing tooling technology, and in particular to a novel burnishing tooling for ball pins. Background Technology
[0002] Burnishing fixtures refer to equipment or tools used in the burnishing process. They are mainly used to rotate batches of parts together with grinding media in a drum at low speed, achieving a finishing effect through the relative movement of the parts and the abrasive. The main function of burnishing fixtures is to remove oil, rust, and burrs from the surface of parts and to smooth the metal surface. Burnishing fixtures are also commonly used in the processing of ball joints. However, existing burnishing fixtures cannot stably clamp and fix the ball joints during processing, and the flying debris generated during processing also makes loading and unloading cumbersome and lacks automation.
