Innovative welding tool clamping device

Abstract

The invention discloses an innovative welding tool clamping device. The device mainly comprises pressing blocks and the like, wherein a connecting block M is installed in the upper middle of a connecting block K, guide rails are installed on the two sides of the connecting block K, an air cylinder A is installed on the connecting block M, the air cylinder A is connected with an angle seat, the angle seat is installed on the guide rails, an air cylinder B is installed on the angle seat, the front end of the air cylinder B is connected with the pressing blocks which are arranged in the circumference by means of hinge pins A and connecting blocks H, supporting blocks and adjusting gaskets A are arranged on the outer sides of the pressing blocks, connecting blocks F and hinge pins B are arranged among the pressing blocks, and positioning pins are arranged beside the pressing blocks. According to the innovative welding tool clamping device, a clamping device for a rear torsion beam brake support is innovated, rapid clamping is achieved, and parts are convenient to take; the accuracy of the caster angle and the toe-in angle of the rear torsion beam brake mounting surface after welding isimproved, the rejection rate of products and the repair workload of unqualified parts are reduced, the product size is stable, and the product percent of pass and the production efficiency are improved; and the effect of being easy to operate is achieved, the service life of a clamp is prolonged, and the cost is reduced.

Description

technical field

[0001] The invention relates to the field of automobile manufacturing, in particular to an innovative welding tool clamping device. Background technique

[0002] Among domestic self-developed models, the quality requirements for the rear torsion beam of the body chassis are strict, and the four-wheel alignment accuracy of the vehicle is high, the production is difficult, the number of accessories is large, and the structure is complex. The above focus will be on the accuracy, stability and speed of the welding tooling. . At present, there are two methods for the production of body chassis parts: the first method is to fix the steel stamping parts on the welding tool, and use the welding equipment and the mixed gas (Ar+O2+CO2) to weld the shape. The specific operation method is: first, use the welding tool The stamping parts are fixed at the first reference point, and then all steel workpieces are clamped, the switch is started, clamped, and the equipment is ...
