摘要 

针对排气管与焊接夹具之间发生运动干涉导致焊接质量不佳的情况以及夹持机构工作周期选择不合理导致夹持机构寿命降低这两个问题。利用CATIA软件设计了一种四爪型焊接夹具,该装置主要由夹持机构和分度机构两大部分组成。将模型导入到ADAMS仿真软件中进行运动学仿真,得到夹持机构与分度机构位移和角度的仿真结果以及夹持机构中四个夹爪在不同工作周期下运动速度、加速度、位移的数据结果,这些结果为解决焊接夹具的运动干涉问题与合理地选择工作周期提供理论依据,从而节省焊接夹具设计周期和成本,提高了焊接夹具工作的可靠性。

Abstract: 

In view of the poor welding quality caused by the motion interference between the exhaust pipe and the welding fixture, and the life of the clamping mechanism reduced due to the unreasonable selection of the working cycle of the clamping mechanism. A four claw welding fixture is designed by CATIA software. The device is mainly composed of clamping mechanism and indexing mechanism. The model is imported into ADAMS simulation software for kinematics simulation, and the simulation results of displacement and angle of clamping mechanism and indexing mechanism, as well as the data results of motion speed, acceleration and displacement of four clamping claws in clamping mechanism under different working cycles are obtained. These results provide theoretical basis for solving the motion interference problem of welding fixture and reasonably selecting working cycle, thus the design cycle and cost of welding fixture are saved, and the reliability of welding fixture is improved.

Key words:  Automotive exhaust pipe    Welding fixture    Clamping mechanism    Indexing mechanism    Motion simulation
