The invention relates to a multi-vehicle-shared automatic flexible main welding production line which comprises a positioning and switching station, an overall splicing station, a repair welding station and a discharging station in sequence. The positioning and switching, the installing of first sub-assemblies, the splicing and welding of different sub-assemblies and the transferring of assembliescan be completed in sequence. According to the multi-vehicle-shared automatic flexible main welding production line, the automatic production of multiple types of bodies in white with different heights is realized; by means of the application of the multi-vehicle-shared automatic flexible main welding production line, a PLC control system controls a robot to perform positioning and switching in four longitudinal beam forms at the positioning and switching station according to input production information, and the positioning uniformity of different vehicle types during subsequent overall splicing and repair welding is ensured; and the overall splicing of multiple bodies in white is realized at the overall splicing station according to different vehicle type information by switching different positioning grippers through the robot, the flexibility of the production line is improved, and repeated investment caused by the later introduction of new vehicle types is reduced.
Description
technical field [0001] The present invention relates to a main welding wire, and more specifically, relates to an automatic and flexible main welding wire suitable for the production of multiple vehicle models in white with different heights. Background technique [0002] With the increasingly fierce competition in the automobile market, the development cycle of new models is constantly shortening. How to use limited resources to meet market demand, quickly realize the production of multiple models, and reduce the impact on the production of existing models has become a major issue for major companies. Difficulties faced by automakers. [0003] According to the planning of the development model, the floor is divided into two types, namely, flat floor and high-low floor. There are four types of longitudinal beams, with a height difference of 120mm and a length difference of 300mm and 600mm; according to different market requirements, different lengths and heights of the body-...
