摘　　要：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 rotation） is 0 - ± 90° while C-axis（ around z-axis rotation） is 0 - ± ∞. A-axis and C-axis can be controlled synchronously by NC system.
