摘　　要：针对航空梁类零件传统加工定位方法中装夹效率低、质量不稳定等问题,基于真空吸附原理设计一种可以实现工件准确定位、快速夹紧的快速定位装夹工艺装备,从而有效抑制切削过程中因刚性不足引起的切削振颤,减小夹紧力不均对加工变形的影响,提高生产效率和加工精度。Aiming at the problems of low clamping efficiency and unstable quality in the traditional machining and positioning method of aviation beam parts,a rapid positioning and clamping equipment based on the principle of vacuum adsorption is designed.It can realize accurate positioning of workpieces and fast clamping,effectively control the cutting vibration caused by rigidity insufficiency in the process of cutting,and reduce the influence of uneven clamping force on machining deformation,so as to improve the production efficiency and machining accuracy.

关 键 词：梁类零件 加工变形 真空吸附 快速装夹
