Surface polishing device for engine oil drain valve sealing gasket production

The invention relates to the technical field of sealing gasket polishing, in particular to a surface polishing device for engine oil drain valve sealing gasket production, which comprises a power supply rod and a main machine which are mutually inserted for use. According to the surface polishing device for engine oil drain valve sealing gasket production, a revolution rod pushes a transverse frame to conduct left-right reciprocating quantitative deflection swing with a supporting column as a base point in the rotating process, and at the moment, a transverse arm coaxially connected with the supporting column conducts synchronous deflection motion; compared with common rotary grinding and polishing, friction polishing is achieved through forward and reverse high-speed shimmy vibration, due to the fact that the movement amplitude of the grinding head is low, the grinding head can rotate in a reciprocating mode, and the grinding head can rotate in a reciprocating mode in a reciprocating mode. When the device is
