Description

Technical Field

[0001] The utility model belongs to the technical field of piston pins, and in particular relates to a piston pin inspection and marking integrated structure. Background Art

[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. Therefore, piston pins of different sizes are required to adapt to different pistons, and the inner wall will be damaged when the piston pin is pierced. In order to increase the brand of the company's products, existing companies often mark the surface of the products. However, the existing inspection and marking use two processes, which require a longer transportation line. The longer transportation line will require more production space. Therefore, it is very important to obtain a piston pin inspection and marking integrated structure that occupies a small production area and can be inspected and marked at the same time.
