Application of UG/WAVE Technology in Automotive Welding Fixture Design

Abstract

In the design of automotive body welding fixture, we are faced with a challenging task. Body parts are usually made of thin-walled metal, and the stability of these parts is insufficient. Especially the car body, its surface presents a complex threedimensional curved shape. In the welding operation, in order to ensure the assembly accuracy of the body parts and the quality of the welding, it is necessary to rely on the positioning and fixing function of the multi-point, which is also designed for the welding operation of the fixture has. The use of WAVE design and related technologies can efficiently deal with the relationship between the fixture positioning surface and the body data, as well as the coordination between the fixture structure and the body data, not only can reduce the repetitive design, but also greatly shorten the design cycle, but also can maximize the advantages of parallel engineering.
