Abstract

The invention relates to an indirect output shaft position measuring device which comprises an angular displacement sensor, a screw rod screw, a screw rod nut and an output shaft. A sensor fork is arranged on a shaft of the angular displacement sensor, and a sliding pair is formed by the sensor fork and a cylindrical boss on the screw rod nut. The output shaft is provided with an output shaft fork, and a sliding pair is formed by the output shaft fork and the cylindrical boss on the screw rod nut. The indirect measurement of a rotation angle of an output shaft of the rotary actuator is achieved, the structure is compact, the space utilization rate is high, and the realization of the miniaturization design of the actuator is facilitated.

Description

technical field [0001] The invention relates to the technical field of output shaft angular displacement measurement, in particular to an installation and debugging method of an indirect output shaft position measurement device. Background technique [0002] For rotary actuators, it is necessary to detect the rotation angle of the output shaft in real time and perform position closed-loop control on it. An angular displacement sensor is usually used to detect the position of the output shaft. According to the different installation methods of the angular displacement sensor and the output shaft, it can be divided into coaxial installation and non-coaxial installation. Coaxial installation belongs to direct measurement, and the sensor reading is the rotation angle of the output shaft. Non-coaxial installation belongs to indirect measurement, and the sensor reading After conversion, the rotation angle of the output shaft can be obtained. [0003] The coaxial installation met...
