Detailed Description

Further advantages and effects of the present invention will become readily apparent to those skilled in the art from the disclosure herein, by referring to the accompanying drawings and the preferred embodiments. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention. It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.

The main assembly station for welding the car body is one of the most important and complex stations in the welding production line. The main assembly station for welding the automobile body usually adopts an OPEN GATE scheme, in the scheme, the clamp on the main assembly station is a rigid clamp, and a set of clamp is correspondingly designed for each automobile model. When the vehicle type is replaced in mixed line production, the clamps are required to be integrally switched, and corresponding clamp storage library positions are required to be increased in the line body according to the number of collinear vehicle types. For example, when the car body welding main assembly station is used for A type main assembly, a set of clamps corresponding to A type is used, and a set of clamps corresponding to B type is placed in the clamp storage library position. When the vehicle type is switched, namely when the vehicle body welding main assembly station is switched from the A vehicle type main assembly to the B vehicle type main assembly, the vehicle body welding main assembly worker needs to switch a set of clamps corresponding to the A vehicle type into a set of clamps corresponding to the B vehicle type, and place the set of clamps corresponding to the A vehicle type in the clamp storage library position. However, in the above-described vehicle body welding main assembly station, the number of jigs is large, and the occupied area of the jig storage library is large, resulting in a large construction cost and occupied area of the vehicle body welding main assembly station. In order to solve the problems, the embodiment of the invention provides a main assembly device and a main assembly system for vehicle body welding.
