[0002] PCB CNC drilling and milling machine is a high-precision, high-efficiency automated mechanical equipment specially used for drilling and milling on printed circuit boards (PCB). PCB, or printed circuit board, is the support of electronic components and the carrier of electrical connections. Its processing quality directly affects the performance and reliability of electronic products. Therefore, PCB CNC drilling and milling machine plays an extremely important role in the electronics manufacturing industry. The machine is equipped with an automatic tool changing system, which can replace different types of drill bits or milling cutters in a short time to meet different processing requirements. Therefore, the cutter head is one of the important structures on the CNC drilling and milling machine, and its main function is to install drilling and milling tools.
[0003] For example, the prior art publication number is CN214185297U, which is a CNC machine tool cutter seat. The utility model utilizes the swing force generated during operation to allow the spring and the movable rail to cooperate with each other, drive the slider on the movable rail, and discharge the gasoline squeezed in the cutter devices on both sides, thereby avoiding the long-term accumulation of engine oil in the equipment, which may easily cause the machine to jam or malfunction, affecting the normal operation of the equipment.
[0004] However, the above-mentioned prior art still has the following problems when used: during the drilling and milling process, the staff needs to adjust the positions of multiple drilling and milling tools on the cutter head according to the PCB drilling and milling requirements. Since multiple drilling and milling tools are often installed on the cutter head, the adjustment is very inconvenient and takes a lot of time. In addition, there will be certain deviations during each installation process by the staff, which will cause errors when the tools are processed on the PCB. Based on this, the utility model provides a PCB CNC drilling and milling machine cutter head that is convenient for adjusting the positions of the drilling and milling tools. Utility Model Content
