Description

Technical Field

[0001] The utility model mainly relates to the field of sensor detection, in particular to a checking fixture used for a displacement sensor of a measuring line of a length measuring machine. Background Art

[0002] The function of a linear displacement sensor is to convert a linear mechanical displacement into an electrical signal. To achieve this, a variable resistor slide is usually placed in a fixed position on the sensor, and different resistance values ​​are measured by the displacement of the slider on the slide. The sensor slide is connected to a steady-state DC voltage, allowing a small current of microamperes to flow. The voltage between the slider and the start is proportional to the length of the slider movement. Using the sensor as a voltage divider minimizes the requirements for the accuracy of the total resistance of the slide, because changes in resistance caused by temperature changes will not affect the measurement results.

[0003] In the invention patent application with application number CN201720135657.8, application publication date 2018.01.12, and titled "A Linear Displacement Sensor Detection Standard Device", a laser interferometer system, a calibration table, a workbench, a displacement drive control system, a data acquisition and processing system, and a fixture are provided. The fixture includes a float-type lifting and rotating moving fixture and a roller support fixture. The float-type lifting and rotating moving fixture includes a float-type V-block assembly and a rotating moving assembly. The device uses a special fixture for the sensor during the sensor installation and positioning process, which can ensure accurate positioning and effectively protect the sensor.

[0004] However, the device cannot be universally installed when facing linear displacement sensors of different specifications, and when facing large quantities of sensor detection, they need to be installed and fixed one by one using specially matched fixtures, which is relatively inefficient.

[0014] 3. Beneficial effects:

[0015] The utility model has a reasonable design.
