减速箱表头易变形铝支架类零件夹具设计

The research of fixture design in deformable aluminum bracket parts of gear box gauge headers

主要介绍一种某企业采用的表头铝支架类零件的夹具设计方法,阐述如何解决铝支架类零件加工装夹时易变形的问题。通过采用支架三个定位柱被放置于夹具三个直孔内的偏心凸轮沿零件中心线压紧方式及采用相互平行与垂直的两工位坐标系为定位基准的两种夹具设计方案,解决了实际问题,并提出在产品生产装夹时应注意的一些技术要点。

This paper introduces an enterprise fixture design scheme in the aluminum bracket parts of gauge headers.It mainly elaborates how to solve the problems of deformation in the process of clamping the aluminum bracket parts. Two fixture design options are included as follows：1.three positioning columns of the bracket are arranged in the three straight holes.They are pressed by the eccentric cam along the center line of the parts; 2.the two position coordinates, which are parallel and vertical, are used as the location datum. These two design options solve the practical problems. And the ttention should be paid to the technical requirement during clamping bracket parts.
