Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a polishing mechanism for wheel hub processing. Background Art

[0002] The wheel hub is also called the wheel rim, steel rim, wheel, or tire bell. It is a cylindrical metal part that supports the tire with its inner profile and is mounted on the shaft. There are many types of wheel hubs, depending on the diameter, width, molding method, and material. Depending on the characteristics and needs of different models, the wheel hub surface treatment process will also take different methods, which can be roughly divided into two types: baking varnish and electroplating. When processing the wheel hub, it needs to be polished.

[0003] The Chinese authorized announcement number is CN219747492U. The polishing machine can perform intermittent and continuous polishing on multiple positions of the wheel hub, thereby improving the polishing efficiency. The rotation of the driving shaft drives the driven shaft connected thereto to rotate through the connecting unit, and the rotation of the driven shaft drives the cam connected thereto to rotate. The rotation of the cam drives the slider connected thereto to slide back and forth in the piston cavity through the connecting rod. The reciprocating sliding of the slider causes a pressure difference to be generated in the piston cavity. When negative pressure is generated in the piston cavity, water in the water tank is sucked into the piston cavity through the connecting pipe, and the water in the piston cavity is transported to the nozzle through the delivery pipe through the extrusion of the slider for spraying, thereby causing the nozzle to cool and reduce dust on the polishing area.

[0004] There are still some shortcomings in use. The wheel hub cannot be clamped and fixed during polishing, but is simply placed on the surface of the placement table. The fixing effect of the wheel hub is poor. The wheel hub may move unexpectedly during polishing, which reduces the polishing quality of the wheel hub. At the same time, broken iron chips generated during polishing will splash, which can easily cause damage to the human body. Utility Model Content
