Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a piston pin grinding device for machining. Background Technology

[0002] A piston pin is a cylindrical pin installed on the piston skirt. Its center passes through the connecting rod small end hole to connect the piston and connecting rod. Its function is to transmit the gas force on the piston to the connecting rod, or to make the connecting rod small end drive the piston to move together. In order to reduce weight, piston pins are generally made of high-quality alloy steel and are hollow. When machining piston pins, they need to be ground. 1. Existing piston pins cannot be firmly clamped during grinding. 2. Existing machining machinery has low grinding efficiency for piston pins. 3. Piston pins are not stable enough during grinding, thus affecting the grinding quality. Therefore, we propose a piston pin grinding device for machining. Utility Model Content
