CATIA automotive fixture beam welding line design and analysis based on Simulation

针对传统车型中的前横梁总成焊接装置不能满足当前汽车生产需求问题,提出一种基于CATIA仿真软件的夹具设计方法,进而缩短研发周期,提高前横梁焊装线设计的性能。对此,文章首先对CATIA软件的具体原理进行了分析,然后结合前横梁焊装线夹具设计的需求,提出本研究的目的。在上述分析的基础上,就前横梁总成的具体构成和主要设计的工件进行了分析。然后利用气动定位夹紧与旋转锁紧结构原理,实现焊接件的快速夹紧,以及3600内多工位旋转及定位,从而完成二维和3D图像的设计。然后采用DELMIA软件对焊接机器人运行轨迹进行规划,并将生成的代码传入到焊接机器人的控制系统之内。最后通过DELMIA设计和运行,证明本文焊接路径的合理性。通过上述的设计,为当前汽车自动化设计提供了借鉴,同时极大的缩短了开发的周期,为当前夹具设计提供了新的方法。

Based on the traditional models of the front crossbeam assembly welding device can not meet the current needs of automobile production, the use of pneumatic clamping and rotating locking structure principle, realize the quick clamping and welding, and 3600 multi position rotating and positioning, so as to complete the two-dimensional image design image. Then the DELMIA software is used to plan the trajectory of the welding robot, and the generated code is introduced into the control system of the welding robot. Finally, through the design and operation of DELMIA, it is proved that the welding path is reasonable.
