Image probe attitude adjustment device and adjustment method thereof

Abstract

The invention relates to an image probe attitude adjustment device and an adjustment method thereof. The device comprises two one-dimensional pitching benches (7), a one-dimensional rotating table (8)and a probe adapter plate (2). The two one-dimensional pitching benches (7), the one-dimensional rotating table (8) and the probe adapter plate (2) are sequentially superposed and assembled to form the attitude adjustment device capable of adjusting the pitching angle [alpha] (rotation angle around the Y-axis), the deflection angle [beta] (rotation angle around the Z-axis) and the rolling angle [gamma] (rotation angle around the X-axis) of an image probe. The adjustment method realizes the adjustment for the pitching angle [alpha] and the deflection angle [beta] of the image probe by adoptinga point laser and an adjustable attenuator and combining the motion of a three-coordinate measuring machine and an image processing technology, realizes the adjustment for the rolling angle [gamma] of the image probe by adopting a cuboid calibration block and combining the motion of the three-coordinate measuring machine and the image processing technology, and finally enables the image probe tobe at the correct measurement orientation. The image probe attitude adjustment device has the characteristics of simple principle and convenient application, solves key problems in the development andapplication of a novel three-coordinate measuring system based on the visual measurement principle.

Description

technical field [0001] The invention relates to a device for adjusting the posture of an image measuring head and an adjusting method thereof, belonging to the technical field of photoelectric measurement. Background technique [0002] In recent years, with the development and progress of science and technology, the requirements for detection accuracy and measurement speed of geometric quantities (such as length, angle, etc.) in various fields have been continuously improved, which largely depends on the development of measuring instruments and detection method improvement. In the past few decades, the detection methods of classical geometric dimensions and shape parameters have become increasingly mature, the most typical of which is the three-coordinate measuring machine. The three-coordinate measuring machine is a comprehensive precision measuring instrument. It is based on precision machinery and integrates electronic technology, numerical control technology, computer t...
