Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tool tool monitoring, and particularly relates to a cleaning device for machining monitoring of a numerical control machine tool tool. Background Technique

[0002] A numerical control machine tool, abbreviated as a CNC machine tool, is an automated machine tool equipped with a program control system; the control system can logically process a program specified by control codes or other symbolic instructions, decode it, represent it in coded numbers, input it into the numerical control device through an information carrier, and after arithmetic processing, the numerical control device issues various control signals to control the actions of the machine tool, and automatically processes parts according to the shape and size required by the drawing.

[0003] Among them, the tool life of a numerical control machine tool is an important indicator to measure the tool performance, which not only affects the machining efficiency of parts, but also is crucial for the quality of products. For a production line, it is an object of key concern for quality control; due to no human intervention and complex tool types in the production line, during use, if the tool life cannot be controlled in time, minor problems will be batch quality problems, and serious problems will be equipment collision accidents; therefore, it is necessary to record the machining information of the tool in real time, track the usage status of the tool, and conduct online monitoring of the tool life. For the convenience of use, a tool monitoring system is generally installed inside the numerical control machine tool.

[0004] During tool monitoring and detection, due to the relatively complex internal environment of the numerical control machine tool, the rotating workpiece will drive the cutting fluid and cutting chips to fly disorderly in the internal environment of the numerical control machine tool, and the flying cutting fluid and cutting chips are easily adhered to the detection end of the element to be measured, thus covering the element to be measured and affecting the normal detection work of the element to be measured; in the prior art, there are devices for cleaning the element to be measured, but most of the cleaning devices have a single cleaning angle for the element to be measured, and the cleaning device is easily blocked by slag chips such as cutting chips, resulting in damage to the cleaning device and reducing the cleaning effect on the element to be measured.

[0006] Although the cleaning mechanism of the above patent can achieve basic cleaning of the tool, the air outlet angle of the air outlet of the exhaust pipe of the cleaning mechanism is single, and the exhaust pipes for air outlet are arranged up and down, which easily causes dirt to fall and block the exhaust pipe when cleaning the tool, resulting in damage to the cleaning mechanism and reducing the cleaning effect on the tool.
