Description

Technical Field

[0001] The utility model relates to the technical field of piston production and processing, in particular to a spraying device for piston protective oil. Background Art

[0002] Piston protective oil spraying is usually carried out during the piston manufacturing process. The oil film is evenly sprayed on the piston surface through special spraying equipment. This oil film is usually composed of high-quality lubricating oil and additives, and has good wear resistance and chemical corrosion resistance. Spraying piston protective oil can extend the service life of the piston and improve the performance and reliability of the engine. In addition, it can also reduce the friction between the piston and the cylinder body, reduce energy loss and emissions.

[0003] However, when spraying protective oil on the piston surface, it is usually necessary to clamp the piston to prevent the piston from being unstable during spraying, resulting in uneven surface spraying. However, some existing spraying devices usually clamp the piston surface during actual use to make the spraying more stable. However, clamping the surface will cause the clamping part to be not sprayed in place, thereby reducing the spraying effect of the device on the piston. Therefore, it is urgent to solve the above problems. Utility Model Content
