[0002] The automobile frame refers to the skeleton structure of the automobile, including the door frame and the main frame. It is an important component that supports the entire body of the automobile. The automobile frame is usually made of steel or aluminum alloy, and has sufficient strength and rigidity to withstand the weight of the vehicle and the effects of various forces. When the automobile is damaged and maintained, the door frame needs to be welded and repaired. When welding the door, the existing automobile door welding station fixes the door and then repairs it through a welding machine, but both the front and back sides of the door need to be welded and repaired, which results in the staff manually unfixing the door frame and flipping it over to fix it after repairing one side, which greatly increases the welding time and reduces the maintenance effect. At the same time, after the door frame is welded, the welding slag will continue to remain on the outside of the door frame, thereby reducing the welding quality of the door frame.
