Problems solved by technology

After comparative analysis, this technology has shortcomings. It can only be used to clamp mechanical parts during the machining process, but it is obviously not suitable for clamping thin plate workpieces to be laser welded, nor is it suitable for the automobile compartment to be welded. Clamping when the model number of the back cover is changed

Description

technical field [0001] The invention relates to a flexible welding jig, in particular to a flexible welding jig for laser welding the rear cover of an automobile compartment welded by a robot. Used in the field of mechanical engineering. Background technique [0002] When the laser welding of the back cover of the car compartment is performed by the robot, the welding fixture for clamping the back cover of the car compartment needs to be specially designed. Another problem is that in fact, a set of corresponding sets of laser welding is required for a type of car back cover in production. Adaptive welding jig, when laser welding another type of car back cover, you need to use another set of welding jigs that are compatible with it, that is, whenever welding a type of car back cover, you need A welding jig adapted to it cannot adapt to the requirement of replacing a new model in time due to the time period of designing and processing the welding jig, and at the same time, it...
