Abstract

The invention discloses a cable-type displacement sensor calibration device and a calibration method. The cable-type displacement sensor calibration device includes a linear guide rail, a laser interferometer slide table, a spindle slide table and a spindle slide table slidably arranged on the linear guide rail in sequence. A pull-wire displacement sensor slide, the laser interferometer slide is provided with a laser interferometer, the spindle slide is provided with a spindle, and the pull-wire displacement sensor slide is provided with a calibrated pull-wire displacement sensor, The pull-wire displacement sensor calibration device includes a first induction wire calibration fine-tuning sleeve, a second induction wire calibration fine-tuning sleeve, an induction wire calibration fine-tuning plate and a handle for fixing the starting end of the induction wire of the pull-wire displacement sensor. Induction wire fixing element. The wire displacement sensor calibration device aims to solve the technical problems of inconvenient clamping, small measuring range, large Abbe error and poor safety caused by the calibration scheme of the wire 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 ...
