Abstract

The invention relates to the technical field of robot testing, in particular to a robot joint motion precision measuring device. The robot joint motion precision measuring device comprises a base, a joint support, a first sliding table and a second sliding table, wherein the joint support is fixedly mounted at one end of the base, the second sliding table is movably arranged at the other end of the joint support, the first sliding table is movably arranged on the base and arranged between the joint support and the second sliding table, a torque and rotating speed sensor and an angle encoder are arranged on the first sliding table, a servo motor and a speed increaser are arranged on the second sliding table, a robot joint is arranged on the joint support, during testing, the robot joint, the angle encoder, the torque and rotating speed sensor, the speed increaser and the servo motor are sequentially connected, and one side of the first sliding table and one side of the second sliding table are each provided with an adjusting mechanism and a locking mechanism. According to the robot joint motion precision measuring device, the robot joint can be directly tested, and the accuracy and test efficiency of robot joint motion precision measurement are improved.

Description

technical field [0001] The invention relates to the technical field of robot testing, in particular to a measuring device for robot joint motion accuracy. Background technique [0002] Robots are outstanding representatives of contemporary high-end intelligent equipment and high-tech, and an important symbol to measure a country's manufacturing level and core competitiveness. The robot joint is the core component of the robot. Its motion accuracy is an important indicator of the robot joint. It is of great significance for evaluating the performance of the robot joint. At the same time, it can be used to adjust the parameters of the robot and improve the motion performance of the robot. [0003] The robot joint is mainly composed of a servo motor and a precision reducer. In traditional tests, the servo motor and the precision reducer are tested separately as two components. In actual engineering, due to factors such as manufacturing and assembly, it is impossible to determi...
