Then, in order to facilitate subsequent installation, the rubber pad on the top of the valve core is usually frosted. The current process of frosting the surface of the workpiece is mainly carried out by combining a sander and a corresponding fixture to form a grinding equipment.

[0003] For example, Chinese patent CN2 1 9767793U discloses an aluminum product grinding device, which drives a fixed seat on a rotating table to rotate through a motor, fixes the workpiece through an abutment rod controlled by an electric push rod on the fixed seat, and then grinds the surface of the workpiece through a grinding roller on a grinding machine.

The overall cost is high and it is difficult to meet the needs of mass production.

[0005] Based on this, the utility model designs a valve core rubber pad grinding device with automatic unloading to solve the above problems. Utility Model Content
