Description
Technical Field
[0001] The utility model relates to the technical field of electric vehicle frame processing, in particular to a fixing fixture for welding an electric vehicle frame. Background Art
[0002] In the manufacturing process of electric vehicles, the frame is a key component, and its quality and structural stability directly affect the performance and safety of electric vehicles. Welding is one of the important links in the production of electric vehicle frames, and an efficient and reliable fixing fixture is crucial to ensure welding quality. The traditional electric vehicle frame welding process often has the following problems: the shapes and sizes of the frames are diverse, and there are large structural differences between different models of electric vehicle frames. Traditional fixing fixtures are usually only applicable to frames of specific shapes and sizes, and have poor versatility. This leads to the need to frequently replace fixtures when producing different styles of electric vehicle frames, and the frame cannot be rotated in all directions. The welders need to change their positions to weld the frame, which reduces work efficiency and increases labor. Therefore, we propose a fixing fixture for electric vehicle frame welding to solve this problem. Utility Model Content
