摘要:
A macro-micro actuated distended guide rail precision rotation apparatus, having a housing of a torque motor and a bearing housing, both fixedly arranged on an upper surface of a base, and a bearing sleeved on the bearing housing. The inner ring of the bearing sleevingly connected to an intermediate rotating body connected to a bearing inner ring cap. A grating is provided at a lower end of the bearing inner ring cap. A connecting piece is arranged on the upper surface of the housing of the torque motor. The lower end of the connecting piece is fixedly connected to a rotary shaft of the torque motor. The connecting piece and the intermediate rotating body are both connected to the lower end of a fine movement mechanism fixedly connected to a rotary worktable. The rotation apparatus allows for highly precise macro-and-micro linked control, and for rotation control of great rotation range.
