Automobile elbow welding device

Abstract

The invention discloses a welding device for an automobile bent pipe. The welding device is used for welding the bent pipe and a bent plate together. The welding device comprises a machine frame, a working table installed on the middle portion of the machine frame, welding gun assemblies installed on the top of the machine frame, and welding positioning clamps installed on the working table. Each welding positioning clamp comprises a base, a first supporting assembly installed on the base and used for supporting the bent pipe, a first positioning mechanism used for positioning the bent pipe, a second supporting assembly used for supporting the bent plate, a second positioning mechanism used for positioning the bent plate, a third positioning mechanism used for positioning the bent plate, and a fourth positioning mechanism used for positioning the bent plate. By means of the welding device for the automobile bent pipe, all parts of the bent pipe and the bent plate can be rapidly and effectively positioned, the feeding time and the discharging time are greatly shortened, and the work efficiency is improved; by arranging cambered surfaces matched with the bent pipe or the bent plate on all supporting pieces and limiting the shape of the bent pipe and the bent plate, the influence, generated during machining, on welding is effectively reduced, and the machining quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of forming automobile parts, in particular to an automobile elbow welding device. Background technique [0002] With the progress and development of society, automobiles occupy an indispensable position in people's lives. However, as people pay more and more attention to the performance and safety of vehicles, the machining accuracy, efficiency and yield of vehicle parts have also been improved. in the work schedule. [0003] Among them, in the welding process of the automobile elbow, due to the uniqueness of the shape of the elbow and the shape of the bent plate welded with it, the problem of clamping and positioning has not been solved. In the past, after positioning by standard fixtures, the The pipe body is welded, but this method not only reduces the processing efficiency, but also greatly reduces the yield due to the difficulty of processing, and the processing quality is also affected, which directly...
