A Parameter Database for Virtual Design of an Auto-body Welding Fixture

Automobile welding fixture design directly influence the production quality and exploitation cycle of automobile body. Computer aided fixture design has become a research focus in recent years. This paper is focused on the design feature and process of welding fixture based on module design and parameter design theory. A virtual design system for automobile welding fixture is presented and a structure system of fixture parts is established. The application of this system will reduce the static and dynamic adjustment of welding fixture, improve the fixture design level and shorten the design cycle.
