摘　　要：针对某精密轴承套件批量生产类型下钻铰孔夹具设计问题,提出三种类型装夹方案,采用三维装夹变形有限元分析方法分析夹紧方式,得出径向夹紧力所产生的应变应力最小且满足装夹需求。提出一种V形块定位和轴向气动夹紧的装夹方式,并运用多件装夹设计思想实现在数控机床上完成多件装夹功能,进而提高工件装夹效率。For the problem of the design of drilling and reaming fixture for a precision bearing sleeve in batch production,three types of clamping schemes are proposed,three-dimensional clamping deformation finite element analysis method is used to analyze the clamping mode,and it is concluded that the strain stress generated by the radial clamping force meets the clamping requirement minimally.The clamping method of V-shaped block positioning and axial pneumatic clamping is proposed,and the multi-piece clamping design idea is used to realize the multi-piece clamping function on CNC machine tool,thereby improving the clamping efficiency of workpiece.
