Description

technical field [0001] The invention belongs to the technical field of industrial robots, and in particular relates to a comprehensive test platform for joint reducers of industrial robots. Background technique [0002] As an important carrier of automation, industrial robots have become an important symbol to measure a country's manufacturing level and technological level. The joint reducer is the core component of an industrial robot, and its cost accounts for about 30% of the cost of the entire industrial robot. Industrial robot joint reducers require large transmission ratio, high rigidity, high motion precision, high transmission efficiency, small backlash, and stable load. Its main performance indicators are: transmission accuracy, transmission efficiency, torsional rigidity, hysteresis, torsional vibration amplitude and temperature rise. They play a decisive role in the control accuracy of the position of the mechanical arm of the industrial robot, the stability of ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional test method, the test of the main performance indicators of industrial robot joint reducers such as transmission accuracy, transmission efficiency, torsional rigidity, hysteresis, torsional vibration amplitude, and temperature rise requires the use of multiple special test equipment for testing. Repeated installation and adjustment on multiple devices is time-consuming and laborious, and the test efficiency is low, which cannot meet the production requirements of full inspection. Moreover, the repeatability of installation accuracy is poor, resulting in large fluctuations in test results and low accuracy.
