[0002] The piston pin is a cylindrical pin installed on the piston skirt. Its middle part passes through the small end hole of the connecting rod and is used to connect the piston and the connecting rod. Its function is to transmit the gas force borne by the piston to the connecting rod, or to make the small end of the connecting rod drive the piston to move together. In order to reduce weight, the piston pin is generally made of high-quality alloy steel and made hollow. As a commonly used mechanical component, the demand for piston pins is very huge, so a large number of production and processing have been carried out; during the processing, it is often necessary to process and grind the outer surface of the initially produced piston pin. If the outer surface of the piston pin is relatively rough and not smooth, it is likely to affect the use of the piston pin. Therefore, the grinding device for the piston pin is particularly important. Therefore, it is very important to obtain an integrated mechanism for through-grinding and cutting of piston pins.
