Abstract

The invention discloses a mechanical part surface defect detection device, a detection method and a related device, and the mechanical part surface defect detection device achieves the recognition anddetection of surface defects of a to-be-detected part based on machine vision, does not need to depend on the artificial physiological and psychological states, the surface defect recognition and detection precision of the to-be-detected part can be improved, and the problems of missing detection, false detection, low efficiency and high labor cost are avoided. Meanwhile, the mechanical part surface defect detection device is provided with the first type part positioning module and the second type part positioning module, can be used for detecting the surface defects of different types of to-be-detected parts, and is beneficial to improving the applicability of the mechanical part surface defect detection device.

Description

technical field [0001] The present application relates to the technical field of construction machinery, and more specifically, to a detection device, a detection method and related devices for surface defects of mechanical parts. Background technique [0002] With the implementation of the national strategy of Made in China 2025, China's manufacturing is gradually transforming into China's intelligent manufacturing, and more and more emphasis is placed on realizing personalized design, flexible manufacturing, and networked operations. Under the background of the world's intelligent manufacturing era, higher and higher requirements are put forward for the intelligence and quality level of the product manufacturing process, and many complicated manual operations will be gradually replaced by machines. [0003] During the process of machining or forming mechanical parts from forged or cast blanks to finished products, surface defects will inevitably occur, such as: black skin,...
