Problems solved by technology

At present, tools such as through gauges, stop gauges, and vernier calipers are mainly used for the inspection of the size of the processed parts, and manual inspection is still the main method, and the inspection efficiency is very low.
For the detection of the length of each section of the stepped shaft with a relatively large height difference, manual detection is not only time-consuming and laborious, but also prone to large measurement errors

Description

technical field [0001] The invention relates to the application of a laser measurement technology, in particular to a large height difference stepped axis detection device and a detection method. Background technique [0002] In the processing and manufacturing industry, the processing of parts, whether it is the processing process or the quality and performance after processing, requires a lot of inspection work. At present, tools such as general gauges, stop gauges, and vernier calipers are mainly used for the detection of process dimensions of machining parts, and manual detection is still the main method, and the detection efficiency is very low. Manual detection is not only time-consuming and labor-intensive, but also prone to large measurement errors. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention overcomes the existing defects, and provides a large height difference stepped shaft detection device and detection method, ...
