Problems solved by technology

However, although the existing light curtain micrometer sensor solves the problem of shaft diameter detection, it cannot correct the small error problem caused by the fact that the axis is not perpendicular to the light curtain micrometer sensor when clamping

Abstract

The present invention discloses a shaft diameter detection device and a detection method. A device system mainly comprises a base, a calibration device, an X-direction movement device, a Z-direction movement device and a high-precision movement detection device. Through rotating two pairs of light curtain micrometers installed on a Z-axis rotation device for certain angles, A1 and B1 values are obtained as calibration values, for a shaft to be detected, A2 and B2 are obtained as measurement values, the calculation is carried out on the measurement values and the calibration values, and the diameter of the shaft to be detected is obtained, the above operation is carried out again, and an average is taken as a measurement value of the diameter of the shaft after three times of measurement.

Description

technical field [0001] The invention relates to a shaft diameter detection device and a detection method, which is an online detection system and belongs to the field of machine vision. Background technique [0002] Machine vision is a comprehensive technology that integrates digital image processing, machinery, control, optics, computer and other technologies. Machine vision systems can realize non-contact detection of targets, can quickly obtain a large amount of information, and are easy to automate. Therefore, machine vision technology has attracted people's attention as an important detection technology, and has been more and more widely used in the detection field. [0003] At present, the diameter measurement of shaft parts is still completed by hand-held traditional detection instruments. The detection personnel are easily affected by the on-site environment, resulting in large errors in diameter measurement results and low measurement accuracy. The shortcomings of...
