[0002] The wheel hub is also called the rim, wheel, or tire bell. It is a cylindrical metal part with the inner contour of the tire supporting the tire and the center mounted on the shaft. The manufacturing process of the wheel hub is very complicated. According to the production process, it mainly includes some production and processing steps such as raw material dissolution, mold preparation, casting, casting molding, X-ray detection, high-temperature heat treatment, machining, runout detection, dynamic balance detection, water leak test, sandblasting, powder spraying, finished product off-line, radius load test, bending force test, impact test, finished product packaging, etc. Among the various processing operations in wheel hub manufacturing, powder spraying refers to the use of powder spraying equipment to spray powder coating on the surface of the wheel hub. Under the action of static electricity, the powder will be adsorbed on the surface of the wheel hub to form a powder coating, which can improve the corrosion resistance and aging resistance of the wheel hub. During the powder spraying process of automobile wheel hubs, the automobile wheel hubs to be sprayed are usually placed on a rotating mechanism. The motor of the rotating mechanism drives the support table used to support the automobile wheel hubs to rotate, and the wheel hubs rotate accordingly, which is conducive to the uniform spraying of powder. The motor is the core component of the rotating mechanism. When the motor fails, the spraying work must be suspended, affecting the progress of the spraying work. Therefore, a rotating mechanism for automobile wheel hub powder spraying is proposed to ensure the smooth progress of the spraying work. Utility Model Content
