Angular displacement sensor zero adjustment device and method

Abstract

The invention belongs to the technical field of angular position detection mechanism debugging and particularly relates to an angular displacement sensor zero adjustment device and method. Zero adjustment is difficult in the installation process of an angular displacement sensor, and the signal consistency error between redundancy is large. According to the angular displacement sensor zero adjustment device and method, a plurality of pairs of precision selection holes are formed in a long edge beam of a supporting frame, the precision selection holes are threaded holes, a notch is formed in the middle of a short edge beam of a rectangular frame, and the notch is provided with a first through hole in the vertical direction; a second through hole in the vertical direction, an open slot communicated with the second through hole and a connecting hole perpendicular to the open slot are formed in one end of a connecting rod arm; the upper end of an adjusting shaft penetrates through the first through hole and the second through hole and then is clamped at the end part of a connecting rod, and the lower end is connected with an adjusting rotating shaft of an angular displacement sensor; and fine adjustment screws are symmetrically installed in the selected precision selection holes, and the swing angle of the connecting rod is adjusted by adjusting the fine adjustment screws. According to the angular displacement sensor zero adjustment device and method, zero adjustment is convenient and simple, zero adjustment precision is high, consistency is good, and adjustment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of debugging an angular position detection mechanism, and in particular relates to a device and method for adjusting the zero position of an angular displacement sensor. Background technique [0002] In the aircraft cockpit control system, in order to detect the angular displacement signal of the control system, an angular displacement detection device is installed. The angular displacement sensor converts the control position of the cockpit into an electrical signal and transmits it to the flight control system. The commonly used angular displacement sensor is RVDT , There is a gear on the RVDT, and then it meshes with the gear on the input shaft of the steering column. How to improve the reliability of the steering command, four sets of RVDT are used to mesh with the gear on the input shaft at the same time. When assembling, adjust the RVDT by rotating the RVDT body The electrical zero position of each RVD...

AI Technical Summary

Problems solved by technology

[0003] It is difficult to adjust the zero position during the installation process, the signal consistency error between the margins is large, and the maintenance is inconvenient, etc.

At the same time, in order to meet the mechanical interconnection between the driver and the co-driver, it is inconvenient to adjust the zero position accuracy in the adjustment, time-consuming and labor-intensive, and the consistency accuracy of the four sets of RVDTs is not high
