Calibration system and measurement method thereof

Abstract

The invention provides a calibration system which comprises a calculation unit, an optical transmitting and receiving device, a reflector, a rotary table and a guide rail, wherein the reflector is installed in the center of the rotary table, the guide rail is connected with a guide rail sliding block, the optical transmitting and receiving device is installed on the guide rail sliding block, the optical transmitting and receiving device is suspended right above the reflector, and the optical transmitting and receiving device is connected with the computing unit. The invention also provides a measurement method of the calibration system. The system has the beneficial effect that the included angle data of the guide rail moving shaft and the rotary table rotating shaft can be accurately collected.

Description

technical field [0001] The invention relates to a precision measuring instrument, in particular to a calibration system and a measurement method of the calibration system. Background technique [0002] In precision measuring instruments, especially in the cylindrical coordinate measuring system, it is often required that the guide rail movement axis Z is parallel to the turntable rotation axis θ, such as figure 1 In order to form an ideal cylindrical coordinate system to achieve precise measurement. But in fact, no matter how it is adjusted, there must be a space angle α between the motion axis of the guide rail and the rotation axis of the turntable. Since the two axes are virtual, this angle cannot be accurately measured or compensated. [0003] The existing traditional practice is to use the standard cylinder to adjust, through repeated adjustment, make the center of the standard cylinder pass the axis of the turntable, and then use the standard cylinder as the benchmark...

AI Technical Summary

Problems solved by technology

[0005]1) After adjustment, no clear angle data can be obtained, so it is difficult to perform high-precision compensation

[0006]2) Since the fixture data cannot be obtained, it is necessary to adjust the parallelism to an ideal level as much as possible, and repeated adjustments are required, which is inefficient and difficult to achieve the ideal level Effect;
