A swing joint module for an inner routing robot

Abstract

The invention discloses a swinging joint module of a robot with wires arranged internally. The swinging joint module comprises a base, a joint output part, a drive motor and a power transmission mechanism; the interior of the base is divided into a motor installation cavity and a power transmission mechanism installation cavity by a division plate; the drive motor is arranged in the motor installation cavity; the power transmission mechanism is arranged in the power transmission mechanism installation cavity and comprises a bevel gear transmission mechanism and a harmonic reducer, a main shaft of the drive motor is connected to driving bevel gears of the bevel gear transmission mechanism, a driven bevel gear of the bevel gear transmission mechanism is connected to the harmonic reducer, and the joint output part is connected to the harmonic reducer; the division plate is provided with wire arrangement holes; the interior of the harmonic reducer is of a hollow structure. The swinging joint module of the robot with the wires arranged internally is simple and compact in structure, the forward rotation and reverse rotation gaps of joints are greatly reduced, and the joint transmission accuracy is high; the internal wire arrangement is adopted, and therefore the appearance is simple and attractive, and the use safety and the reliability are improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a swing joint module of an inner wire routing robot. Background technique [0002] Robot technology has made great progress so far, but there is still a considerable distance to be widely and widely used in social production and human life. The reason is that important factors include the function, performance and intelligence of the robot itself, as well as the complexity and high cost of the system. Although robots have great flexibility and elasticity for certain applications, most of the existing robot systems often have only one main function and fixed configuration for specific purposes and occasions, lacking functional expansion and reconfiguration. structural. Synthesizing and integrating multiple functions in one body is an important trend in the development of robotic systems at present and in the future. In addition, it costs a lot to develop a specific robot for eac...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure is more complicated;

[0005] 2. In the transmission chain, it is decelerated by the harmonic reducer first, and then decelerated by the bevel gear. It is difficult to eliminate the gap between the bevel gear and the precision of the joint transmission is difficult to guarantee;

[0006] 3. The wiring is implemented outside the module, which is neither beautiful nor safe and reliable
