Description

Technical Field

[0001] The utility model relates to a welding tool for automobile parts, in particular to a welding tool for an automobile back door assembly. Background Art

[0002] The rear door of a car refers to the trunk door of a hatchback or SUV, which is mostly flip-up. It is the most important opening part of the car body and plays a very important role in vehicle opening, luggage storage, decoration, parts repair, etc. The quality of the rear door is mainly reflected in its anti-collision performance, sealing performance, opening and closing convenience and other performance indicators.

[0003] The structure and manufacturing process of the traditional automobile tailgate assembly are as follows: the tailgate outer panel assembly and the tailgate inner panel assembly are hemmed and welded to form the tailgate sheet metal assembly, and then the tailgate decorative panel is snapped onto the tailgate sheet metal assembly to form the automobile tailgate assembly. Among them, the tailgate inner panel assembly is welded by the tailgate inner panel, hinge reinforcement plate, pneumatic support rod reinforcement plate, and lock mounting plate. It needs to be welded and assembled after the steel plate is stamped. The cost of the steel structure tailgate is low, but the weight is large, which is not conducive to the lightweight of the tailgate. In addition, the number of parts required is large, and the manufacturing process is complicated. At the same time, the welding process brings about tolerance accumulation, which reduces the assembly size accuracy of the tailgate. In the welding process of an existing automobile hood assembly welding tool, multiple fixtures are required to complete the entire welding. The cost is high, and the time cost increases due to the need for multiple clamping during the welding process, which is time-consuming and labor-intensive. Utility Model Content
