Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, and more specifically, to a milling cutter wear detection device. Background Technique

[0002] In the mechanical processing industry, with the continuous increase in the requirement for processing accuracy, the problem of tool wear has become increasingly prominent. For a ball-end milling cutter with a special double helix structure, the structure of its flank face is intricate, making the measurement of the wear amount particularly difficult. Currently, most enterprises still rely on the experience of workers for subjective judgment and lack an accurate and efficient wear detection method.

[0003] Chinese Patent CN112496861A discloses a ball-end milling cutter wear detection device, in which the light source support rod adopts an inverted L-shaped design. Although this design may bring certain convenience in the light source layout, it may also affect the detection accuracy due to the introduction of an additional vibration source. At the same time, the inverted L-shaped structure may lack sufficient stability when bearing external forces, thereby posing a potential threat to the stability of the light source and the lighting effect. In addition, this patent does not involve any safety protection measures, such as setting up a protective cover, and these measures play an indispensable role in ensuring the safety of operators.

[0019] Working mode: First, take a photo of the unused new milling cutter and save it as a reference image. After the milling cutter has been used for a period of time, insert it into the insertion pipe, and take a photo with the camera. The photo of the milling cutter is first subjected to histogram equalization to improve the image contrast, then mean filtering is used for denoising, and then threshold segmentation is carried out to separate the wear information of the milling cutter from the background. Through image edge extraction, the edge information of the image is extracted to ensure the accuracy of subsequent image recognition, and then it is compared with the reference image to determine the wear state of the milling cutter. Through data analysis and processing, the efficient monitoring of the wear state of the milling cutter is realized.
