Description

technical field [0001] The invention belongs to the field of mechanical automation, and in particular relates to a visual thread automatic detection device and a use method. Background technique [0002] The screw thread is one of the first simple machines invented by mankind. Thread has the advantages of easy assembly and disassembly, which makes it widely used in machinery manufacturing, aerospace, nuclear power, chemical industry, military industry and other fields. In addition to the mechanical properties of threaded parts related to materials and processing technology, the processing quality of geometric parameters is also an important factor affecting its performance. Therefore, the detection of thread geometric parameters is an important link in the production process of threaded parts. Measurement and analysis of threads can effectively reduce the use of unqualified threads and prevent connection failure. Most of the traditional thread detection methods are manual...

AI Technical Summary

Problems solved by technology

Most of the traditional thread detection methods are manual detection. Thread gauges are used for contact detection. Workers judge whether the product to be tested is qualified according to the manual detection results. The workload is heavy, the work efficiency is low, and the measurement results are easily affected by human factors. Not only the lack of measurement efficiency, but also the lack of overall qualification basis, which can no longer meet the actual needs of production
