介绍一种新型的三主轴并联式数控双摆轴回转工作台，这种工作台有3个平行的回转主轴，安装在一个壳体中，转角轴伺服电机带动一对圆锥齿轮和两对圆柱齿轮及介轮驱动3个主轴同步转动，回转工作台的转位轴伺服电机通过一对蜗杆、蜗轮驱动工作台转位。回转工作台的A轴（绕x轴转动）转位范围为0～±90°，C轴的（绕z轴转动）转角范围为0～±∞；在数控系统的控制下，可以实现A、C轴联动。

A new NC bi-rotary three-spindle parallel type rotary table was introduced.It had three parallel rotary spindles mounted in a housing.A motor drove three parallel spindles to rotate synchronously by a bevel gear and two cylindrical gears and idle gear,another motor drove rotary table to rotate by a pair of worm gear and worm.The rotation range of A-axis (around the x axis rota-tion)is 0 ~ ±90°while C-axis (around z-axis rotation)is 0 ~±∞.A-axis and C-axis can be controlled synchronously by NC sys-tem.
