Equipment is used for welding of automobile white body top cover, which is composed of two robots, an optical fiber laser, wire feeding machine, welding head, laser protection room and floor clamp. In the work, a robot is used to weld the welding head with a laser welding head.
The top cover clamp is carried by the robot, and the top cover is matched with the positioning support frame of the two sides by four V type positioning blocks. The top cover clamp is clamped by four clamping cylinders on the positioning support frame. A fast changing device is arranged between the top cover clamp and the robot. Different from the traditional spot welding technology, laser welding can achieve the molecular combination of two steel plates, popular is the hardness of a steel plate after welding.
It will enhance the strength of the body 30%, with the same body accuracy is greatly improved, on the other hand, can reduce the lap width and some strengthening components, can also compress the volume of the body structure, thereby reducing body weight.
