异形件拐臂的加工工艺探究

Research on processing technology of a special-shaped crank arm

介绍了异形件拐臂的结构特点;针对拐臂的加工难点,改进加工方案,设计制作了专用的装夹工装,解决了异形件装夹困难、形变难以控制、粗糙度不合格的问题。结合以往加工经验,通过选择合理的加工顺序、刀具和切削参数,保证了工件的粗糙度,实现了工件的批量生产,降低了生产成本,为公司创造了可观的经济效益。

This paper introduces the structural characteristics of the special-shaped crank arm; to solve the difficult problem of the clamping of the special parts,control of the deformation and disqualification of the roughness,it has designed and manufactured the special clamping tool aiming at the processing difficulty of the crank arm,and has improved processing plan of the crank arm. Combined with the previous processing experience,it has improved the roughness of parts,achieved the mass production of parts and reduced production costs for the company to create a considerable economic benefit by selecting a reasonable processing sequence,cutting tools and cutting parameters.
