Abstract

The invention proposes a guide tool for on-site calibration of a linear displacement sensor. The guide tool includes: a bracket assembly, a guide rail assembly, and an attitude adjustment assembly; the guide rail assembly is installed on the bracket assembly through the attitude adjustment assembly. By adjusting the displacement of the bracket assembly and the spatial attitude of the attitude adjustment assembly, the guide rail assembly becomes the linear displacement reference required for on-site calibration of the line displacement sensor, and the reference is used to assist the on-site calibration of the line displacement sensor. The embodiment of the invention has the technical effects of simple structure, stability and reliability, and strong versatility.

Description

technical field [0001] The invention relates to the technical field of sensor calibration and large-scale laser measurement, in particular to a guide tool for on-site calibration of linear displacement sensors. Background technique [0002] Aircraft development requires a large number of tests, and the test cycle is long. A large number of linear displacement sensors are installed and used on the test bench, and the sensors need to be disassembled regularly and sent to the measurement room for calibration. Some linear displacement sensors cannot be disassembled because they are solidified in the system; they are not allowed to be disassembled due to the positioning relationship with the test bench entity; they are not easy to disassemble when they are connected to the signal line of the test bench test system; The test environment is different from the temperature and electromagnetic environment of the measurement room, which makes the calibration results obtained inconsist...
