新型白车身焊接定位单元设计及力学分析

The design and mechanical analysis of new kind of welding positioning unit for body in white

针对传统焊接定位单元占用车身输送系统空间,可能造成的空间干涉,提出一种基于SCARA机器人的新型焊接定位单元方案设计。该方案采用类似SCARA机器人的旋转结构和可以伸缩的滚珠丝杠升降机解决这一问题,并对旋转臂用Workbench进行力学分析,从而证明结构的合理性和方案的可行性。

Traditional welding positioning unit occupancies the space of vehicle transportation system, which may causes space interference. According to this situation, a program of new welding positioning unit design based on SCARA robots is proposed. The problem can be solved by a similar rotating structure of SCARA robots and retractable ball screw lift in the program. There are mechanical analysis on the rotary arm based on workbench, which prove the rationality of the structure and the feasibility of the program.
