Description

Technical Field

[0001] The utility model relates to the technical field of tool processing, in particular to a detection device for tool wear. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. The vast majority of cutting tools are machine-used, but there are also hand-used ones. Cutting tools used in mechanical manufacturing are basically used for cutting metal materials. Tool wear detection devices are important tools in the manufacturing industry to ensure processing quality and efficiency.

[0003] At present, cutting tools need to be clamped for wear during processing and use. Existing detection methods mostly use tool wear detectors to detect wear through camera units. However, cutting tools may be rusted and adhered with debris during processing and use, which leads to inaccurate wear detection results. Based on these problems, Chinese patent CN212964474U discloses a detection device for tool wear detection. Through the setting of a screw module, the effect of automatic detection can be achieved after the operation of the tool clamping mechanism. At the same time, the screw module has the function of precise positioning, which can avoid inaccurate wear detection due to deviation in orientation. At the same time, through the setting of the tool processing mechanism, the water pump can be used to detect the wear of the cutting tool. The tool is cleaned of rust or rinsed, and then air-dried by a hot air blower to complete the pre-cleaning effect. The hot air blower and the water pump will swing with the fixed rod as the center during operation, thereby cleaning the tool over a larger area, further improving work efficiency. The detection device for tool wear detection has the advantages of pre-cleaning, automatic detection and high detection accuracy, which solves the problem that the current tool needs to be clamped for wear during processing and use. The existing detection method mostly uses a tool wear detector to detect wear through a camera unit. The tool may be rusted and adhered to debris during processing and use, which leads to the problem that the wear detection result is not accurate enough.

[0004] The device uses a water pump to flush rust and debris on the surface of the tool. When the rust and debris have a strong adhesion, a lot of flushing water will be required and it will take a long time, which will not only cause a large amount of water waste, but also hinder the normal progress of tool wear detection.
