摘要
为实现对某型薄壁壳体零件加工变形的控制,文章从零件的加工工艺技术条件出发,结合刀具的切削力以及产品装夹时的夹紧力对产品变形的影响。通过有限元软件分析其变形状态,并依据理论分析结论改进设计夹具。实践证明,该型夹具结构简单,操作便捷,极大地减少了该型产品夹具因素对加工变形的影响,对类似弱刚度产品加工夹具设计提供了参考。
In order to control the deformation of a thin-walled shell parts,this paper is based on the processing technology of the parts,and the influence of the cutting force and the clamping force on the deformation of the product. The deformation state is analyzed by finite element software,and the design fixture is improved according to the analysis conclusion. Practice has proved that the fixture structure is simple and easy to operate. It greatly reduces the influence of the fixture on the machining deformation. It provides a reference for the design of similar products.
