在汽车车桥焊接过程中,焊装夹具的设计中的定位选取、调整机构设计的不合理性及焊装夹具制造过程中工件公差的不合理性会影响车桥焊接后的整体尺寸精度,导致汽车悬挂装配精度不好。本文从设计及制造两个方面入手,分析原因并提出合理解决办法。 In the welding process of automobile axles, the positioning selection in the design of the welding fixture, the unreasonableness of the adjustment mechanism design and the unreasonableness of the workpiece tolerance in the welding fixture manufacturing process will affect the overall dimensional accuracy of the axle after welding, resulting in Automotive suspension assembly accuracy is not good. This article starts from the two aspects of design and manufacture, analyzes the reasons and puts forward the reasonable solutions.
