[0002] A gauge comparator is a metrological instrument for comparing and measuring the length of gauges. In precision displacement measurement, mainly for comparative measurement, an Ubbelohde interferometer or other types of comparative measurement instruments are used to measure the length microdifference between two measured parts to obtain the measurement result, which is widely used in the metrology field.

However, it also has higher reliability, stability, accuracy, and reproducibility.

After one measurement at a certain position of the gauge, the XY motion module drives the positioning member to move in the horizontal and vertical directions, and the gauge and the positioning member move together. Since the probe of the detection component does not move in the horizontal and vertical directions, in fact, the relative position of the probe of the detection component to the gauge has changed, so as to achieve the effect of measuring different positions of the gauge.

[0007] Preferably, the XY motion module includes an X linear module, an X guide rail, a middle moving plate, a Y linear module, and a Y guide rail; The X linear module and the X guide rail are arranged in parallel on the base.

This can improve the motion balance stability on both sides of the top moving plate and the middle moving plate.

[0013] Preferably, a number of parallel protrusions are provided on the upper end surface of the ceramic workbench. This can reduce the influence on the temperature of the gauge block.

[0014] Preferably, a temperature difference placement table is provided on the base around the ceramic workbench. The gauge block to be measured can be placed on the temperature difference placement table in advance to make its temperature consistent and avoid the influence of temperature difference on the measurement accuracy.

[0015] Preferably, a number of parallel protrusions are provided on the upper end surface of the temperature difference placement table. This can reduce the influence on the temperature of the gauge block.

[0016] Preferably, it includes a rectangular parallelepiped holding block, and a limiting groove corresponding to the thickness of the gauge block is provided on the end face of the holding block. So that when measuring the height of the gauge block, it can be stuck in the limiting groove to avoid the gauge block from falling down.
