Abstract

The invention discloses a system for testing a comprehensive performance of a reducer for a robot joint. The system comprises a mechanical part and an electric control part; the mechanical part comprises a servo motor, a measured reducer, an angle measuring device, a torque sensor and a loading arm coaxially connected in sequence; all the parts are fixed on a horizontal guide rail by a bracket; the measured reducer is provided with a temperature sensor; the electric control part comprises an industrial control computer, a motion control card, a data collecting card, a counting card and a temperature collecting module; the motion control card is connected with the servo motor by a servo driver; the data collecting card is connected with a signal output end of the torque sensor and a torque monitoring end of the servo driver; the counting card is connected with a signal output end of the angle measuring device; and the temperature sensor is connected with a computer serial port by the temperature collecting card. According to the system for testing the comprehensive performance of the reducer for the robot joint, the comprehensive performance of the reducer for the robot joint can be tested; and the system is simple in structure, high in test precision and high in universality.

Description

technical field [0001] The invention relates to a reducer for a robot joint, in particular to a comprehensive performance test system for a reducer for a robot joint. Background technique [0002] The robot joint reducer is the basic component of a multi-degree-of-freedom robot. It is also the core functional component of many industrial robots, such as spot welding robots, palletizing robots and handling robots. The quality of its comprehensive performance directly affects the working performance of the robot. With the development of world industry, the demand for automation products such as robots is increasing, especially for automobile production lines, so it is necessary to develop, design and manufacture more high-performance robot joint reducers to meet the needs of robot equipment. This requires us to study the comprehensive dynamics and tribological characteristics of the robot joint reducer, such as efficiency, life, transmission accuracy, starting torque, stiffnes...
