摘　　要：根据机械手的工作特点和运动情况,设计合理的运动循环图。运用SolidWorks三维建模软件中的Motion分析,结合弧面凸轮在工作中的运动特点,完成整个弧面凸轮的运动仿真,从而建模弧面凸轮。设计的单臂双手式的弧面凸轮式机械手可以同时完成插刀动作和拔刀动作。与其他驱动方式相比,它能够更加高效且可靠地交换主轴与刀库中刀具,提高加工中心的自动化水平。The tool-changing manipulator is an indispensable part of CNC machining.According to the working characteristics and movement of the manipulator,a reasonable motion cycle diagram is designed in this paper.Through the use of Motion analysis in SolidWorks 3D modeling software,combined with arc cam the movement characteristics in the work,complete the movement simulation of the entire globular cam,thereby completing the modeling of the globular cam.The single-arm two-hand cambered cam manipulator designed in this paper can perform tool insertion and tool extraction at the same time.Compared with other driving methods,it can complete the exchange of the spindle and the tool in the tool magazine more efficiently and reliably,and improve the machining center,and degree of automation.
