Abstract

The invention discloses an angle calibration device for a speed reducer detector and an angle calibration method of the angle calibration device. The angle calibration device comprises an adapter shell, a calibration rod, a circular grating angle measurement system and a bearing, the two end faces of the adapter shell are fixedly connected with the high-speed end and the low-speed end of the speedreducer detector respectively. The calibration rod is arranged in the hollow part of the adapter shell, and external splines at the two end parts of the calibration rod respectively match internal splines at the high-speed end and the low-speed end of the speed reducer detector to transmit motion; the circular grating angle measurement system comprises a circular grating ruler and a circular grating reading head, and the circular grating ruler is fixed on the calibration rod; the bearing comprises an inner ring and an outer ring, the inner ring is matched with the calibration rod, and the outer ring is matched with the adapter shell. According to the invention, the real operation condition of the tested speed reducer can be simulated, the measurement of the angle value of the gap generated between the input shaft and the output shaft of the speed reducer and the detector in a spline connection mode can be realized, and the error compensation is carried out on the angle value in related parameters of the performance of the speed reducer influenced by the gap value.

Description

technical field [0001] The invention relates to angle calibration, in particular to a calibration device and calibration method for angular geometric quantities in a reducer detector, which ensures the authenticity and accuracy of the angle measurement value of the reducer detector. Background technique [0002] As a transmission device, the reducer has a wide range of applications in the field of machinery and automation. Especially in the field of robotics, the reducer is used as a joint device, and its transmission accuracy, transmission efficiency and other performance parameters affect the working accuracy and service life of the overall system, so there are different types of reducer detectors to realize the detection of reducer parameters. In order to ensure that the reducers produced and sold meet the corresponding performance parameter indicators. [0003] At present, the existing reducer testers generally adopt the method of multi-level components arranged in seri...
