A multi-parameter visual measurement system for bearing inner ring based on comparative measurement method

Abstract

The invention discloses a comparative measurement method-based multi-parameter vision measurement system of an inner ring of a bearing. The multi-parameter vision measurement system comprises a swing-rod barrier feeding mechanism, an axial parameter measurement apparatus, a radial parameter measurement apparatus, a conveying mechanism, a separation mechanism, a PLC control module, an upper computer control module and a man-machine interaction module. According to the measurement system, with utilization of a standard and high-precision inner ring of a bearing as a reference component as well as a camera as a comparative measurement instrument, a measured outer ring of a bearing is compared with the reference component so as to carry out separation of a qualified product, a reprocessed product and a scraped product based on calculation of a localization error of the outer ring of the bearing. Therefore, not only can automatic comparative measurement of the inner hole diameter of the inner ring of the bearing, the outer diameter, the diameter of a groove, a curvature radius of the groove and the width be realized, but also a bottleneck problem that the system cost is too high due to a requirement of a high resolution ratio of a camera during the high precision detection and large-size detection of the inner ring of the bearing can be solved.

Description

technical field [0001] The invention relates to the field of measurement and testing, in particular to a multi-parameter visual measurement and automatic sorting system for bearing inner rings based on a comparative measurement method. Background technique [0002] Bearings are an important basic component in the machinery industry. In the production process of bearings, the machining accuracy of each component of the bearing directly affects the performance and life of the bearing. Therefore, the quality inspection of various parameters of the inner ring of the bearing has always been the concern of the manufacturer. important question. At present, most bearing manufacturers still rely on mechanical, electronic, pneumatic and optical measuring instruments to detect the inner ring of the bearing offline. However, due to the large production volume of the inner ring of the bearing, it is difficult to use manual inspection. Realize online inspection and full inspection of pro...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-parameter visual measurement system based on the comparative measurement method for the on-line detection and full detection of the inner ring of the bearing, which not only solves the problems of high labor intensity and easy introduction of human error when using manual detection

Moreover, by adopting the comparative measurement method, the bottleneck problem of high system cost caused by the high resolution of the camera in the high-precision detection and large-size detection of the inner ring of the bearing is solved.
