白车身焊装生产线数字化夹具设计系统开发及应用

Design and Application of Body-in-white Welding Production Line Fixture Digitized Design System

针对多平台、高节拍汽车车身柔性焊装自动化生产线研发过程的用户化和专业化,基于CATIA软件平台开发了汽车白车身焊装生产线数字化夹具设计系统,进行了涵盖从白车身焊装生产线布局规划到夹具设计工程图生成各个模块功能的研究与开发,基于MBD技术实现了夹具二维工程图自动批量出图,解决了夹具设计数字化与我国以二维图纸作为加工标准现状的衔接问题,大幅度提高了汽车白车身夹具设计自动化与数字化程度,实现了夹具设计的快速高效,极大地缩短了产品开发周期。该系统已在企业投入应用,实际应用该系统夹具设计效率提高40%以上。

In order to improve BIW welding fixture design automation, fixture digital design system was developed based on CATIA plat- form, including serial modules for fixture design processes, especially 2D drawing generation module, By means of MBD technology, this mod- ule was realized to generate bateh drawing automatically, so the problem of connecting fixture design digitization with two-dimensional drawing processing standard in China was solved. This system can make fixture design quick and efficient, welding fixture development cycle was short- ened highly. Appfications in enterprise prove this system can improve 40% welding fixture design efficiency.
