Angle adjustment mechanism-based measurement calibration method, device and angle adjustment mechanism

Abstract

The present invention discloses an angle adjustment mechanism-based measurement calibration method, an angle adjustment mechanism-based measurement calibration device and an angle adjustment mechanism. The method includes the following steps that: a first fixed connection coordinate system corresponding to a first servo angular displacement table and a second fixed connection coordinate system corresponding to a second servo angular displacement table are established, when the two servo angular displacement tables are both at angle origins, a reference coordinate system is established on the basis of the swing axes of the two servo angular displacement tables; the two servo angular displacement tables are controlled to output a first angle and a second angle respectively, and the tilt angle of a standard reflection board with respect to the reference coordinate system is obtained according to the measurement of a self-collimator; on the basis of a transformation relation, a calculation model for mapping the first angle and the second angle to the reference coordinate system is established; and the calculation model is utilized to obtain the actual included angle of the two servo angular displacement tables on the basis of the tilt angle. With the angle adjustment mechanism-based measurement calibration method, the angle adjustment mechanism-based measurement calibration device and the angle adjustment mechanism provided by the embodiments of the present invention adopted, the measurement calibration of the intersection angle of the two servo angular displacement tables is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of industrial control, in particular, to a measurement and calibration method, device and angle adjustment mechanism based on an angle adjustment mechanism. Background technique [0002] The angle adjustment mechanism is a device that controls the angle adjustment of the workpiece when CNC (Computer numerical control, computer numerical control machine tool) performs processing operations. At present, the angle adjustment mechanism formed by the linkage of two servo angular displacement stages is widely used, and the angle adjustment of the workpiece is realized by controlling the required angle output by the two servo angular displacement stages. [0003] In the prior art, two servo angular displacement stages are usually assembled in an assembly manner in which the swing axes are orthogonal, so that the two servo angular displacement stages form a 90-degree orthogonal form.
