[0002] In the field of automobile manufacturing, as a key component, the welding quality of the pull rod directly affects the safety and stability of the automobile driving. In the traditional automobile pull rod welding operation, the design of the fixed structure has significant defects, which becomes an important factor restricting the improvement of welding efficiency and quality.
[0003] At present, the fixed structure form used in most automobile pull rod welding is relatively single, and lacks the ability to flexibly adjust the pull rod shape. In the actual production process, due to differences in vehicle models and different functional requirements, automobile pull rods show diversified characteristics in terms of shape size, bending angle, joint shape, etc. However, the fixed structure of the existing welding device often can only be adapted by replacing the mold when facing such complex and variable pull rod shapes. Each time the mold is replaced, the operator needs to perform tedious disassembly, installation and debugging work. This not only requires the enterprise to reserve a large number of molds of different specifications, occupies a large amount of storage space, and increases production costs, but also greatly reduces production efficiency due to the time spent on frequent mold replacement, which is difficult to meet the current demand for efficient and large-scale production in the automobile manufacturing industry. At the same time, during the mold replacement process, if the installation and debugging are not in place, it may also cause welding position deviation, thereby affecting the pull rod welding quality, increasing the scrap rate, and further increasing the production cost.
