Abstract

The invention discloses a stay wire type displacement sensor calibration device and a calibration method. The stay wire type displacement sensor calibration device comprises a linear guide rail, and alaser interferometer sliding table, a main shaft sliding table and a stay wire type displacement sensor sliding table which are sequentially arranged on the linear guide rail in a sliding manner, wherein a laser interferometer is arranged on the laser interferometer sliding table; a main shaft is arranged on the main shaft sliding table; a calibrated stay wire type displacement sensor is arrangedon the stay wire type displacement sensor sliding table. The stay wire type displacement sensor calibration device further comprises a first induction line calibration fine adjustment sleeve, a second induction line calibration fine adjustment sleeve, an induction line calibration fine adjustment plate and an induction line fixing element used for fixing the starting end of an induction line of the stay wire type displacement sensor. The stay wire type displacement sensor calibration device aims at solving the technical problems that the clamping is inconvenient, the measuring range is small,large Abbe errors are prone to be caused and the safety is poor due to a calibration scheme of a linear displacement sensor in the prior art.

Description

technical field [0001] The invention relates to the technical field of displacement sensor calibration equipment, in particular to a cable-type displacement sensor calibration device and a calibration method. Background technique [0002] The pull wire (rope) type displacement sensor is a kind of linear displacement sensor that relies on the distance pulled out by its own induction wire (rope) to achieve measurement. Widely used in equipment manufacturing, engineering construction and other fields, it has the characteristics of high precision, good stability and convenient use. In the prior art, there are the following calibration schemes for linear displacement sensors: [0003] (1) Use the gauge block as the standard device, and the pull wire (rope) displacement sensor directly measures the standard gauge block. The nominal value of the gauge block is the input value of the pull wire (rope) type displacement sensor, and the difference between the obtained measured value ...
