摘　　要：针对刀库自动换刀装置中的凸轮,通过传统的空间包络共轭原理设计计算弧面凸轮,根据平面四连杆运动特性设计计算了平面槽凸轮,利用VC6.0编写凸轮设计程序,生成两种凸轮的加工数据与凸轮廓面数据,将廓面数据导入Pro/E,对自动换刀机构中凸轮实体进行建模与装配,装配过程中,及时修改了装配错误,重新绘制了零件图,特别是针对凸轮Pro/E建模,能够验证设计凸轮加工数据的正确性,分析了设计过程中出现的弧面凸轮的薄脊问题,运用Pro/E对自动换刀机构的运动仿真,检测了凸轮机构干涉,最终得出符合运动学特性的ATC凸轮。Aiming at the cam of automatic tool changer device of the knife library, through traditional spatial envelope principle it designed the globoidal carrL According to the kinematic properties of planarfour bar linkage it designed the groove cam. Used VC6.0 to compile cam of design program, the machining data of cam generated by VC 6.0. imported data into Pro/E. The key parts of automatic tool change was modeled and assembled by Pro/E, during the assembly, and eliminated some of the assembly errors, and Redrew some parts drawings. Used Pro/E cam modeling it verified the machining data of cam, analyzed the thin ridge problem of globoidal cam, and used Pro/E to simulate the movement of automatic tool change mechanism, detected the inteference, and found out the cam conforming the kinematics characteristics of automatic tool change mechanism
