Abstract

The invention discloses a method for welding a rear bumper of a vehicle body, and belongs to the technical field of vehicle production. A tool for welding the rear bumper of the vehicle body is used in the method. The method includes: a, clamping the to-be-welded rear bumper of the vehicle body; b, loosening support rod locking screws, and adjusting the distance between support rods to enable welding portions to be folded and fastened; c, loosening movable-sleeve locking screws and workpiece compression screws to enable to-be-welded end faces to be flushed with each other, adjusting the end faces to proper welding positions, and fastening the movable-sleeve locking screws and the workpiece compression screws for positioning; d, welding one of the end faces automatically by a welding machine; e, loosening the movable-sleeve locking screws, rotating chucks by 180 degrees simultaneously, and fastening the movable-sleeve locking screws for positioning; f, welding the other end face automatically by the welding machine to complete welding. By the method, the problems of difficulty in overturning of air cylinders, inconvenience in operation and high cost in welding of the rear bumper of the vehicle body in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a welding method for a tailgate of a vehicle body. Background technique [0002] In the production process of automobile body-in-white, many parts such as the tailgate of the car body need to go through the welding process. The welding of the tailgate of the car body in the prior art requires multiple cylinders to clamp, so there is a problem during the welding operation. The following problems: 1. The cylinder cannot be turned over at will to an angle suitable for welding, which is inconvenient to operate, resulting in low work efficiency; 2. It takes up a lot of space and costs high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for welding the tailgate of a vehicle body. This welding method can solve the problems of difficulty in turning over the cylinder, inconvenient operation and high...
