Description

Technical Field

[0001] The utility model relates to the technical field of cylinder sleeve processing, in particular to a cylinder sleeve hard anodizing device. Background Art

[0002] Cylinder liner hard anodizing is a surface treatment technology that is mainly used to improve the wear and corrosion resistance of metal surfaces. It is particularly common in the automotive industry and other industries involving the use of metal parts. This technology is particularly suitable for aluminum alloy cylinder liners because aluminum alloy itself is soft and easy to wear.

[0003] Hard anodizing is developed on the basis of traditional anodizing. During the anodizing process, the aluminum alloy part is placed in an electrolyte as the anode, and direct current is applied between it and the cathode. When the current passes through the electrolyte, an aluminum oxide film will form on the aluminum surface. This oxide film has high hardness and can significantly improve the scratch and wear resistance of the part surface.

[0004] When the hard anodizing device is in use, the cylinder liner needs to be clamped and fixed. However, the existing hard anodizing devices are generally unable to clamp cylinder liners of different lengths for processing at the same time. Therefore, it is necessary to design a cylinder liner hard anodizing device. Utility Model Content

[0014] 1. A cylinder liner hard anodizing device is used in conjunction with a top plate, a bottom plate, a top sleeve and a bottom sleeve. A motor controls the rotation of a threaded rod. When the threaded rod rotates, the bottom plate is controlled to rise linearly after being guided by a guide rod and a rod sleeve until the top of the cylinder liner is clamped by the top sleeve. Then the device is placed in an oxidation tank for coating. In this way, multiple cylinder liners can be processed at the same time, and the inner and outer sides of the cylinder liners can be coated at the same time, thereby improving the processing efficiency.
