Integrated rotation driving executor

Abstract

The invention discloses an integrated rotation driving executor which comprises a motor, a coaxial speed reducer and a shaft flange. The motor is provided with a motor encoder and driven by a driving circuit board. The input end of the coaxial speed reducer cooperates with the motor. The coaxial speed reducer is provided with a speed reducer encoder. The shaft flange is an output shaft provided with a flange plate. The flange plate cooperates with the output end of the coaxial speed reducer. The output shaft outputs a rotation signal. When the driving executor works, the driving circuit board drives the motor, the rotating speed of the motor and the rotating speed of the output end of the coaxial speed reducer can be obtained through the encoders, the rotating speeds can be adjusted through the driving circuit board according to the rotating speed condition, and precise control can be achieved. According to the driving executor, a driver, the motor, the encoders and the coaxial speed reducer are integrated into a small and flexible whole, and mounting and using convenience is improved. The driving executor is compact in structure, small in size, large in output torque, easy to control, high in control precision and high in safety.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an integrated rotary drive actuator. Background technique [0002] In recent years, with the development of industrial technology, intelligent robots have more contact with people in the fields of industry, medical treatment and service. [0003] Traditional robots use rigid joints with motor-reducer-load linear transmission. Rigid joints have the advantages of simple structure, compact size, and precise positioning, which can meet the requirements of industrial production. However, rigid joints cannot respond to the external environment in a timely manner, which makes robots equipped with rigid joints poor compatibility, low energy efficiency and high energy consumption. When a robot collides with the environment rigidly, it may damage expensive equipment or injure humans and animals. .

Problems solved by technology

However, rigid joints cannot respond to the external environment in a timely manner, which makes robots equipped with rigid joints poor compatibility, low energy efficiency and high energy consumption. When a robot collides with the environment rigidly, it may damage expensive equipment or injure humans and animals.

[0004] At present, the servo is generally separated from the driver and the motor, and the two are connected by cables, so there are many connecting lines, the wiring is troublesome, and the lines are susceptible to external interference, poor contact or aging can easily affect the overall operation

In particular, with the increase of the distance of the encoder line and the enhancement of external environment interference, the communication quality will decrease significantly

[0005] Most of the existing servos use inner rotor motors, which have high cost, large volume, small torque and weak overload capacity

The separation of motor, driver, and encoder makes the line cluttered and the anti-interference ability weak, and leads to a large overall size

[0006] The existing servo has a large overall volume, low cost performance, low energy utilization rate, and low security
