Two-DOF (two-degree-of-freedom) modular joint assembly based on hollow integrated motor

Abstract

The invention provides a two-DOF (two-degree-of-freedom) modular joint assembly based on a hollow integrated motor. The two-DOF modular joint assembly comprises an X-axis movement unit, a connecting unit and a hollow Y-axis movement unit, wherein the X-axis movement unit can rotate around an own axis; the Y-axis movement unit can rotate around an own axis; one end of a bend is connected with a rotating output end of the X-axis movement unit, and the other end of the bend is connected with a fixed end of the Y-axis movement unit; the axis of the X-axis movement unit is perpendicular to that of the Y-axis movement unit. According to the technical scheme, difficulty and complexity of design, mounting and wiring of a multi-joint robot are reduced, design efficiency of the multi-joint robot is improved, and design reliability of the multi-joint robot is enhanced.

Description

technical field [0001] The invention belongs to the technical field of industrial automation. Specifically, the invention relates to a two-degree-of-freedom modular joint assembly based on a hollow integrated motor. Background technique [0002] In the field of robotics, when designing the structure of the robot body, designers usually need to spend a lot of time designing the specific structure and connection methods of the motor, reducer, and connecting rod, and need to repeatedly install and debug. However, according to experience, in many multi-joint robots Among them, the difference in the structure of multi-joint robots of the same level and type is actually small, so the work done by many designers in structural design is repetitive, which wastes the energy of designers to a certain extent. And because such components are not standardized and modularized, the integration of the structure designed by each designer will not be too high, which will increase the occupied ...

[0002] In the field of robotics, when designing the structure of the robot body, designers usually need to spend a lot of time designing the specific structure and connection methods of the motor, reducer, and connecting rod, and need to repeatedly install and debug. However, according to experience, in many multi-joint robots Among them, the structural differences of multi-joint robots of the same level and type are actually small, so the work done by many designers in structural design is repetitive, which wastes the energy of designers to a certain extent.

And because such components are not standardized and modularized, the integration of the structure designed by each designer will not be too high, which will increase the occupied space and weight, and may also be affected by different processing and assembly processes. The emergence of various uncontrollable factors reduces the reliability and stability of the entire mechanism, prolongs the commissioning period and maintenance period, and increases time and economic costs
