Abstract

The invention relates to a fully-automatic large-size measurement equipment field calibration device, which belongs to the field of geometry. An interferometer is used as a length measurement standard to be matched with a linear guide rail, and the standard length between any two points in the linear direction is given; a modular posture adjustment mechanism is used to be matched with a shaft system with pretightening to realize automatic non-deflection rotation of the guide rail at any angle of 0 DEG to 90 DEG through double trapezoidal screw push rods; finally, in match with the interferometer, a standard length under the needed posture is given; and the control system of the whole device and a base are integrated as a whole to realize convenient movement of the calibration device. the problem of low efficiency of the existing calibration device is solved, the modular automatic posture adjustment mechanism is used to automatically realize any posture adjustment of 0 DEG to 90 DEG for the guide rail and the length measurement assembly and the length measurement calibration work under any posture, and the field calibration efficiency of the traditional field calibration device is greatly improved.

Description

technical field [0001] The invention is an on-site calibration device for full-automatic large-scale measuring equipment, which belongs to the field of geometric quantities. Background technique [0002] The current problem for large-scale industrial measurement systems is how to solve the on-site calibration of the measurement system. The fixed-length scale cannot meet the needs of the site in terms of length and accuracy, so some foreign institutions have begun to try to use laser interferometry to solve this problem. At present, the United States has done a lot of work to solve the on-site calibration of coordinate measuring instruments such as laser trackers. [0003] The laser ball bar LBB (Laser Ball Bar) developed by Tetra Precision Company in the United States combines a laser interferometer with a ballbar to quickly calibrate the CNC machine tool and the three-coordinate measuring machine within 1m. [0004] The National Institute of Standards and Technology (Nati...
