Huahui Yang, Fu Liu, Zhou Jun, Feng Weili · 2015
In order to realize the calibration measurement of universal turntable in high precision, a calibration device is designed and realized.The device was mainly composed of horizontal capacitance sensor, mental circular grating, ultrasonic motor, and double-row angular contact bearings was selected as its slewing mechanism, so rotation precision of calibration instrument can be improved.Finally, this paper put the error testing results of calibration instrument each system, which satisfy the demand for calibration measurement and provide references for carrying out uncertainty analysis.
