Problems solved by technology
[0003] At this stage, the comprehensive accuracy test of the harmonic reducer is only a simple measurement. It evaluates the comprehensive accuracy of the harmonic reducer by virtue of the working state of the harmonic reducer during the test process, without the actual tooling state of the harmonic reducer. When the motion data is measured and the specific measurement data is used as the basis for the calculation of the comprehensive accuracy, there is a problem that the comprehensive accuracy test results are highly subjective and the test results are inaccurate

The invention discloses a comprehensive precision testing machine for a harmonic reducer. The testing machine comprises a robot, a load piece, a position detection device, a controller and a processor. The robot is provided with a joint for installing a harmonic reducer to be tested. The load piece is arranged at a tail end of the robot to simulate a rated load, and the controller controls the robot to pass through an extreme position from a starting position and then return to a test position at a rated speed. The position detection device detects actual position information when the robot returns to the test position, the processor compares theoretical position information and actual position information of the robot returning to the test position after passing through the extreme position from the initial position according to the rated speed, and the comprehensive precision of the harmonic reducer is obtained. The comprehensive precision of the harmonic reducer is tested by simulating the actual working state, the comprehensive precision of the harmonic reducer is calculated according to obtained test data, and the accuracy of a comprehensive precision test result is ensured. Besides, the invention also discloses a comprehensive precision testing method for a harmonic reducer.
Description
technical field [0001] The invention relates to the technical field of harmonic reducer comprehensive precision testing, in particular to a harmonic reducer comprehensive precision test machine and a harmonic reducer comprehensive precision test method. Background technique [0002] Under the background of the international intelligent manufacturing industry 4.0, the application of industrial robots is becoming more and more extensive. Harmonic reducer is the core key component of industrial robots, and its performance will directly affect the performance of the entire robot. During the production and processing of the harmonic reducer, it is usually necessary to test the functional performance, rigidity, and comprehensive transmission accuracy of the harmonic reducer. Although many parameters of the harmonic reducer can be obtained after functional performance testing, rigidity testing, and transmission comprehensive accuracy testing; however, even if these parameters are ...
