Description

technical field [0001] The invention relates to the technical field of detection of shaft parts, in particular to an image collection system of a shaft tester and an image collection method thereof. Background technique [0002] The quality of mechanical product parts includes dimensional accuracy, shape and position accuracy, surface roughness, and heat treatment defects, among which the main dimensional accuracy of parts is the most basic content that reflects the quality of mechanical products. Shaft parts are widely used in machinery, automobile, electromechanical and other industries. The machining accuracy of shaft parts directly affects the processing quality of products, so the detection of shaft parts is particularly important. At present, the measurement methods for shaft parts are divided into contact measurement and non-contact measurement. Using contact measurement, the work intensity is high, the efficiency is low, and it is difficult to achieve online measurem...

Problems solved by technology

At present, the measurement methods for shaft parts are divided into contact measurement and non-contact measurement. Using contact measurement, the work intensity is high, the efficiency is low, and it is difficult to achieve online measurement. Non-contact measurement overcomes the above-mentioned defects of contact measurement. , but most non-contact measurement tasks have fewer types of measurement tasks, which fail to fully meet the needs of parameter measurement of shaft parts, and at the same time, the accuracy and efficiency of measurement are not up to expectations
