Abstract

A test equipment calibration device and a calibration method thereof belong to geometric quantity measurement test equipment, are provided to solve the problem that the existing large-size test equipment calibration device needs large investment, has a single function and is hard to popularize and apply, and are used for geometric large-size equipment comprehensive calibration. The test equipment calibration device of the invention comprises a guide rail, a laser interferometer, a head base, a workbench, a tail base and a processor. According to the calibration method of the invention, through the precision length measurement, 2D angle measurement and 2D auto-collimation functions of the high-precision 5D laser interferometer, the accurate characteristic values of a physical standard (or target) installed on the guide rail in different attitudes in corresponding positions can be obtained. The problem that the technical state and test result accuracy of large special test equipment cannot be controlled effectively is solved, and quick and accurate measurement support is provided for product development and product quality improvement.

Description

technical field [0001] The invention belongs to geometric quantity measuring and testing equipment, in particular to a testing equipment calibration device and a calibration method thereof, which are used for comprehensive calibration of geometric quantity and large-scale equipment. Background technique [0002] The existing standard devices used for calibration of large-scale geometric test equipment all use heavy-duty granite precision baseline guide rail system as the operating platform. Accurate measurement function and the precise measurement function of the engraved line spacing that the line comparator has,) are not conducive to popularization and application; and mature length measuring machines and line line comparators and other equipment have small measurement ranges and single functions, which cannot solve the problems of diverse and complex forms. Calibration and verification of various special test equipment with a large amount and a wide range. [0003] For c...
