[0002] During the CNC lathe processing, the chips and coolant residues generated by the drilling and tapping heads can easily affect the processing accuracy and surface quality. Traditional air blowing cleaning methods mostly use a single air pipe in a fixed position, which has the problems of limited adjustment range and insufficient coverage area. Although there are some adjustable air blowing devices in the existing technology, their structure is complex and difficult to adapt to tool heads and workpieces of different heights, and they cannot achieve multi-angle synchronous adjustment, resulting in low cleaning efficiency. In addition, conventional air blowing systems often lack modular design, the air pipe layout is chaotic, and the air path connectivity is poor, which affects the stability of the airflow.
