Problems solved by technology
Among them, the invention patents CN201410093481.5 and CN201410093482.X use the elastic deformation of the material to amplify the measured displacement in equal proportions for calibration, but the scheme does not consider the linear range of elastic deformation of complex components and the clamping accuracy of the sensor
Invention patent CN201410314100.1 uses optical principles for indirect measurement, and the mechanism is complex and difficult to operate
The utility model patent CN201320323961.7 simplifies the calibration process by using electrical equipment such as a data acquisition card computer, but the micro-motion is realized by a stepping motor, and its calibration accuracy is difficult to guarantee

The invention discloses a displacement sensor marking apparatus which is intended for detecting and marking a high precision micro-distance probe. The displacement sensor which is made based on the eddy current theory or inductance theory is often applied to occasions which require high displacement detection precision. Sensors of this kind often require to mark a to-be-probed test piece in the process of production and detection. According to the invention, the apparatus herein includes: a micrometer head which is intended for driving the to-be-probed test piece, a feed rod, an installation pedestal of the feed rod, a to-be-probed test piece installation pedestal which can move freely on the feed rod, a sensor installation pedestal which can achieve angular positioning and a pedestal which positions the aforementioned assemblies. According to the invention, the apparatus herein has the characteristics of high precision, easy operation, and wide application range, and can increase the marking precision of the sensor and also simplify sensor marking.
Description
technical field [0001] The invention relates to the technical field of displacement sensors, in particular to a displacement sensor calibrator, which is used for inspection and calibration of eddy current sensors or inductance sensors during the production process. Background technique [0002] Displacement sensors made using the principle of eddy current or inductance are often used in occasions that require high displacement detection accuracy. This type of sensor has a high sensitivity to the distance from the detected object, and the material properties and surface curvature of the detected object are also affected. It has an influence. In the process of production and inspection, it is often necessary to use the same material and the same surface curvature to calibrate it. The purpose of the displacement sensor calibration instrument is to accurately change the distance between the macro probe of the sensor and the detected object and record the change of the sensor tes...
