摘　　要：汽车焊装夹具的设计直接影响到汽车车身的制造质量和开发周期 ,计算机辅助夹具设计技术逐渐得到重视。本文通过采用模块设计和参数化设计技术 ,研究车身薄板零件焊装夹具的设计特征和设计过程 ,建立了汽车焊装夹具设计分类系统 ,开发出基于实例的汽车虚拟焊装夹具设计参数化零件库。采用该系统将减少焊装夹具的静动态调试时间 ,提高夹具设计水平 。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.
