摘　　要：在大规模定制的工件批量生产中,采用多件装夹方法设计数控夹具装置可以有效地发挥数控加工的高效性,从而提高工件的生产效率。多件装夹应力集中导致夹具体结构出现变形,进而影响数控夹具的精密性。对称式夹具结构可有效解决应力集中变形问题,不仅简化了夹具体结构,也提升了多件装夹后的生产效率。The design of NC fixture with the method of multi-piece clamping,can effectively highlight the high efficiency of NC machining in the mass production of customized work-pieces,thus improving the production efficiency.The deformation of the fixture structure is caused by stress concentration of multi-piece clamping,which affects the precision of NC fixture.In order to avoid deformation caused by stress concentration,a symmetrical fixture structure is recommended to be an effective means for solving this problem,not only simplifying the fixture structure but also improving the production efficiency after multi-piece clamping.
