Torque motor and rod-shaped motor structure

Abstract

The invention belongs to the technical field of torque motors, and particularly relates to a torque motor and rod-shaped motor structure which comprises a rod-shaped motor used for controlling a center shaft to ascend and descend and a DD motor used for controlling the center shaft to rotate, and the axis of the center shaft of the DD motor and the axis of the center shaft of the rod-shaped motor are hollow. The coaxial lines are fixedly connected in the same motor shell; the center shaft of the DD motor and the center shaft of the rod-shaped motor are connected through a spline to achieve sliding in the axis direction. A Z + R shaft mode is adopted, the DD motor and the rod-shaped motor are used for two-shaft driving, then the encoder is used for feedback, the motor precision is high, only the air passing pipe arranged at the middle shaft position is arranged as a moving part, and the weight is light. The center lifting shaft of the rod-shaped motor and the center rotating shaft of the DD motor are connected together through the spline, meanwhile, the air passing pipe is arranged between the center lifting shaft and the center rotating shaft, ventilation can be achieved, the overall structure is effectively reduced, the installation requirement is lowered, and meanwhile later maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of lifting and rotating reclaiming materials, in particular to a torque motor plus a rod-shaped motor structure. Background technique [0002] Torque motor is a special motor with a large number of poles. It can run at low speed or even locked rotor without causing damage to the motor. In torque working mode, the motor can provide stable torque to the load. [0003] At present, when we need the structure of Z-axis motion and R-axis motion, many of them are split structures. Generally, stepper motors or servo motors are used to drive the Z-axis and R-axis motion, and the R-axis is attached to the Z-axis as a whole. This will lead to a large Z-axis load and a large overall footprint, which will directly affect the efficiency when many chip grabs and small products are grabbed. SUMMARY OF THE INVENTION [0004] Based on the above-mentioned technical problems in the prior art, the present invention proposes a...

[0003] At present, when we need the structure of Z-axis movement and R-axis movement, many of them are split structures. Generally, stepper motors or servo motors are used to drive the Z-axis and R-axis movement, and the R-axis is attached to the Z-axis as a whole. This will lead to a large load on the Z axis and a large overall space occupation, which will directly affect the efficiency when many chips are captured and small products are captured.
