[0002] A car wheel cover usually refers to a protective component installed above the car wheel and inside the car body. It surrounds the wheel and is located in the wheel arch area of ​​the vehicle, generally at the four corners of the car body, that is, above the front and rear wheels. It can prevent the mud, gravel, rainwater, etc. kicked up by the wheels during driving from impacting and eroding the car body and nearby chassis parts. When the vehicle is driving on roads with poor road conditions, such as muddy roads or gravel roads, the wheel cover can effectively block most of the flying foreign matter, avoiding scratches on the car body paint and damage to chassis-related components such as brake lines and fuel lines.

[0003] During the processing of automobile wheel covers, nuts need to be projection welded to the surface of the automobile wheel covers. Nut projection welding machines are specially used to weld nuts to other metal parts. However, the current projection welding equipment is difficult to quickly position the automobile wheel cover when projection welding between the nut and the automobile wheel cover. During the projection welding of the automobile wheel cover and the nut, offset is prone to occur, which in turn affects the firmness of the two after projection welding. To this end, we propose a processing and positioning device for projection welding of automobile wheel cover nuts to solve the above problems. Utility Model Content
