A flexible and automatic batch welding line for multi-vehicle side surround tetrahedron

Abstract

The invention discloses a flexible automatic tetrahedron batch welding line for side walls of automobiles of different types and belongs to the field of automobile welding. A welding robot is located between a left tetrahedron mechanism and a right tetrahedron mechanism which are distributed on the two sides of the welding robot symmetrically. The sides, away from the welding robot, of the left tetrahedron mechanism and the right tetrahedron mechanism are each provided with an automatic turnover foot board. Drive and driven mechanisms in each tetrahedron mechanism are arranged on drive and driven rotary bases respectively. The drive and driven rotary bases are each provided with a fine positioning mechanism. The two ends of each tetrahedron are fixedly connected with the corresponding drive and driven mechanisms respectively. Each tetrahedron is provided with a clamp, and servo driving mechanisms drive the drive mechanisms to rotate. The upper end face of a welding rack in an automatic puppet welding system is fixedly connected with one end of an automatic welding tong mechanism, and one end of the welding point of the automatic welding tong mechanism is fixedly connected with a copper bar which is provided with at least one puppet welding tong mechanism. By means of the technical scheme, the invested cost of a welding production line can be reduced, and the production efficiency can be remarkably improved.

Description

technical field [0001] The invention relates to the field of automobile welding, and more specifically relates to a flexible and automatic batch welding line for tetrahedral side walls of multiple vehicle models. Background technique [0002] At present, in the automobile industry, when various automobile manufacturers develop models, each new model will consider a derivative model, that is, the same platform, multiple styling and other characteristics, resulting in a production line equipped with multiple sub-assembly lines. How can the production line be realized? How to reduce the production cost to the greatest extent, and how to minimize the floor area of ​​the production line have become the problems that many automobile manufacturers have to solve. [0003] As far as a single model is concerned, the left and right sides are basically symmetrical. In the traditional welding production, the left side and right sides need to be manufactured separately. The input cost is ...
