Welding tool, welding production line and welding method of vehicle

Abstract

The invention relates to a welding tool, a welding production line and a welding method of a vehicle. The welding tool comprises a base and multiple clamps used for fixing a vehicle to be welded. Thebase is provided with a welding machine position used for storing the clamps and a storing position. The clamps are arranged on the base in a sliding manner so as to slide from the welding position tothe storing position along the preset path, or slide from the storing position to the welding position. In this way, by means of the multiple clamps, the vehicle to be welded can be fixed, welding isconvenient, meanwhile, the multiple clamps are arranged on the base in a sliding manner, the vehicle located on the storing position can be switched to the welding position sequentially to be welded,production of the whole vehicle is not influenced, switching time is short, and the working efficiency is improved. In addition, the welding tool is wide in application range, applicable to the samevehicle model and different vehicle models, simple in structure, convenient to operate, flexible and efficient.

Description

Technical field [0001] The present disclosure relates to the welding field of vehicle body side walls, and in particular, to a welding tool, a welding production line and a welding method of a vehicle. Background technique [0002] With the rapid renewal of cars, in order to meet the design requirements of different models, new models that are upgraded and modified are generally designed on the basis of a unified modular platform with new shapes and corresponding body side panels. In related technologies, the welding production line, especially the welding production line based on the side panels of the car body, mainly has two forms: one is manual loading, manual welding, and station arrangement. Each model has a production area. The welding production line only It is suitable for a single vehicle, with a large floor area, low equipment utilization and low economic benefits; the second is to grasp the parts manually or robots, and realize positioning and clamping through variabl...

Problems solved by technology

In related technologies, the welding production line, especially the welding production line based on the side wall of the body, mainly has two forms: one is manual loading, manual welding, and sequential arrangement of stations. Each vehicle model has a production area. The welding production line only Adapt to a single car model, occupy a large area, low equipment utilization, and low economic benefits; the second is to use manual or robot grippers to realize positioning and clamping through variable position or shared fixtures, and the robot performs welding and transports them to subsequent work The welding production line can be used for 2-3 models, but the number of models produced on the same line is reduced, which cannot match the body assembly line with multiple models. The introduction of new models takes a long time, which affects work efficiency
