Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of processing equipment for supersonic thermal spraying, in particular to a supersonic spraying inner hole self-venting vertical rotary table. BACKGROUND

[0002] Supersonic thermal spraying is a high-tech process that allows the surface to "wear armor". It deposits molten or semi-molten spraying material on the surface of the workpiece through supersonic airflow, forming a high-performance coating that can significantly improve the performance of parts in terms of wear resistance, corrosion resistance, and high-temperature resistance.

[0003] In the field, some workpieces need to be treated by supersonic thermal spraying on the inner hole wall of the workpiece, such as the inner wall of hydraulic oil, valve body, and various deep-diameter ratio sleeve and cylinder parts.

[0004] However, the existing vertical rotary table has the following problems: 1. The existing rotary table only supports the function of rotating the workpiece. When facing workpieces with inner holes, a large amount of smoke and dust is generated during spraying with a thermal spraying gun.
