Integral welding workstation and vehicle production line

Abstract

The invention provides an integral welding workstation and a vehicle production line, and relates to the technical field of vehicle manufacturing equipment. The integral welding workstation comprisesa general gripper library, a welding clamp library, a robot, a general ground positioning device, a general abutting positioning device and a control device; the general ground positioning device is used for positioning a lower vehicle body positioning trolley; the general abutting positioning device is arranged near the general ground positioning device, and is used for positioning and mounting apositioning gripper; the positioning gripper can position and grab a lower vehicle body assembly; the robot is arranged near the general gripper library, the welding clamp library and the general abutting positioning device; under the control effect of the control device, the robot can grab the positioning gripper, and the positioning gripper positions or grabs the lower vehicle body assembly; and the robot can grab welding clamps from the welding clamp library to realize the welding process of the lower vehicle body assembly. The integral welding workstation relieves the problems of incapability of switching fixtures, weak equipment generality and high cost in the prior art.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing equipment, in particular to an integrated welding workstation and an automobile production line. Background technique [0002] With the rapid development of China's economy and the maturity of the automobile industry, the development trend of automobile demand has gradually changed from mass production to small-volume, personalized customization. In the case of balancing customer needs and R&D and production costs, automakers have higher and higher requirements for the mixed-line production capacity of the production line. [0003] At present, the common production line is the collinear production of models on the same platform. Because the models on the same platform have the same body positioning and similar production process, the production line is similar in equipment and structure, and can realize collinear production. Due to the differences in body positioning and producti...

Problems solved by technology

[0006] 1) The problem of site occupation. According to the previous plan, a car model needs to separately design a set of lower body assembly fixtures and repair welding of the lower body. It needs to occupy the welding site, welding equipment, repair welding site, and repair welding equipment. If there are multiple models Simultaneous development requires the occupation of multiple welding sites and welding equipment;
