[0002] Numerical control machine tools, also known as CNC, are machine tools controlled by electronic digital signals. Milling cutters are the main tools, and the accuracy of the tools is directly related to the quality of milling processing. In the actual processing process, a large amount of debris will be generated when the tool cuts the workpiece, and the debris will fall into the machine tool workbench or adhere to the tool. Although there are intelligent mechanical devices to assist in chip blowing, they have not yet been popularized. Most of them still use traditional chip removal methods. The traditional removal method is that after a workpiece is processed, the staff opens the CNC cabinet door and uses a handheld air gun to blow and spray the workpiece and the inside of the device, and blows the debris into the chip removal port of the machine tool to prevent the debris from interfering with or damaging the tool and affecting the accuracy of the tool. The traditional problem is that it is necessary to detect multiple times whether there are impurities such as steel wire and iron chips adhering to the milling cutter, or whether the chips are all over the processing platform, and it is necessary to blow and spray again and again, which lacks continuity, is very troublesome and affects the processing efficiency. For this reason, an air-blowing CNC tool chip removal mechanism is proposed. Utility Model Content
