A/C axis double pendulum milling head driven by inner rotor torque motor

Abstract

The invention discloses an A / C axis double pendulum milling head driven by a inner rotor torque motor. The A / C axis double pendulum milling head comprises an upper unit, a lower unit, and an AC connecting plate, wherein the upper unit comprises a C axis, first inner rotor torque motors and first transmission connecting pieces, and the lower unit comprises a box body, an A axis located in the box body, a second inner rotor torque motor and a second transmission connecting piece. The AC connecting plate is arranged between the upper unit and the lower unit, the first transmission connecting pieces are fixedly connected with the upper end of the AC connecting plate, and the lower end of the AC connecting plate is fixedly connected with the box body. The central line of the C axis is arrangedin up-down direction, the first inner rotor torque motors drives the C axis and the AC connecting plate to rotate through the first transmission connecting pieces, the second inner rotor torque motordrives the A axis to swing through the second transmission connecting piece, and the swing plane of the A axis is parallel to the center line of the C axis. According to the A / C axis double pendulum milling head, the A axis and the C axis are driven by the inner rotor torque motor, the transmission links are few, the transmission mode and the layout are simple, the transmission is stable, the precision is high, the heat dissipation is good, and the torque is large.
