Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a non-contact detection device and method for shape error accuracy of rotating parts. Background technique [0002] With the rapid development of manufacturing technology in industrial fields such as automobiles, machine tools, home appliances, and aviation, and the increasing requirements of customers for product quality, the inspection link in the product manufacturing process has become more and more important. The reasonable establishment of tolerances in the part design process and the correct detection of tolerances in the manufacturing process are crucial to the quality of the product. Among them, the shape and position error is an important technical index to evaluate the manufacturing quality of parts. Especially in precision machinery, instrumentation, aerospace and various high-tech equipment, the shape and position errors of parts are often the key to the work...

AI Technical Summary

Problems solved by technology

[0003] In the process of workpiece shape and position error detection in the prior art, most of them still use manual methods to complete various shape and position accuracy detection by rotating the workpiece, which has high labor intensity, low work efficiency, and poor reliability of detection results.

However, with the rapid development of computer technology, the detection methods are undergoing qualitative changes. At present, most of them have started to use three-coordinate measuring machines or tool microscopes, but such equipment is expensive, complicated to operate, high in environmental requirements, and low in detection efficiency. , and because this type of equipment is generally a contact measurement, it is easy to damage the probe or scratch the surface of the measured entity, and this type of equipment is not suitable for the measurement of the surface of flexible material products, because when the penetration touches the surface of the workpiece to be measured, it will change the object Therefore, in actual production, it is more and more urgent to provide corresponding special equipment for the detection of shape and position errors of workpieces.
