摘　　要：设计了一种双弧面凸轮驱动的数控双回转工作台装置,对该工作台所用伺服电动机做了预选,并对回转台电动机进行了校核计算。结果表明:预选电机满足设计要求;该工作台控制两个伺服电机来实现双回转轴联动,使回转工作台能满足多品种弧面凸轮铣削加工以及部分具有不可展开复杂曲线曲面工件加工的需要;该装置具有工作台回转减速机构和工件回转减速机构,且该双回转工作台的减速机构均采用弧面凸轮机构,进一步提高了加工精度、稳定性和降低摩擦损耗。A double cam-driven CNC double rotary table was designed.The motor used in the worktable was preselected,and the rotary table motor was checked and calculated.The result show that the preselected motor meets the design requirements.The rotary table has two rotary coordinates and a linear coordinate.The control servo motor can realize double rotation shaft linkage,and can process some workpiece with undeveloped complex curved surface or curve.The device has a table rotary deceleration mechanism and a workpiece rotary deceleration mechanism,and the deceleration mechanism of the double rotary table adopt camber deceleration mechanism,which further improves the machining accuracy,stability and reduces friction loss.
