Abstract

The utility model relates to movement parameter calibration technology, in particular to a movement parameter calibration mechanism which solves the problems of limitations of current single parameter calibration on the movement parameters, and no device capable of simultaneously implementing multi-parameter calibration on the movement parameters. The movement parameter calibration mechanism comprises a large crank-link mechanism, a small crank-link mechanism and a rack; the large crank-link mechanism comprises a large motor, a large wheel disc in interference fit with the large motor, a large link in interference fit with the large wheel disc, and a large guide rail pair; and the large guide rail pair consists of a large guide rail and a large carriage. The movement parameter calibrationmechanism completely solves the problems of limitations of current single parameter calibration on the movement parameters, and no device capable of simultaneously implementing multi-parameter calibration on the movement parameters, and is applied to movement parameter calibration.

Description

technical field [0001] The invention relates to a motion parameter calibration technology, in particular to a motion parameter calibration mechanism. Background technique [0002] The calibration of motion parameters mainly includes the calibration of displacement, velocity, and acceleration; at present, the calibration of displacement is mainly calibrated by dual-frequency laser interferometer and laser Doppler measuring instrument; when using dual-frequency laser interferometer to measure and calibrate, due to the principle Due to the limitation, the frequency difference based on the Zeeman effect splitting is 15-20MHz, and the general measurement speed is <1m / s. High-speed measurement is limited; when using a laser Doppler measuring instrument for measurement and calibration, the fastest known measurement speed is the LV-8600 laser interferometer of Japan ONO SOKKI Company, which uses the laser Doppler measurement principle to achieve The maximum measurement speed is ...
