The bottom end of the connecting column 16 is fixedly connected to a piston 19. The lower surface of the piston 19 is elastically connected to the bottom wall of the connecting cylinder 15 through a second spring 20. The model of the cylinder 7 can be selected as SC32-25-S. The milling cutter assembly 9 is a prior art and is widely used in society. When in use, the workpiece is placed on the base 1, and the mounting plate 8 can be driven to move downward by starting the cylinder 7, and the mounting plate 8 can drive the milling cutter assembly 9 thereon to move downward. When the milling cutter assembly 9 moves to an appropriate position, the workpiece can be processed, and the mounting plate 8 can drive the slider 14 to move and drive the connecting column 16 to move downward through the connecting assembly when moving downward. The movement of the slider 14 can squeeze the first spring 12, and the downward movement of the connecting column 16 can drive the piston 19 to move downward, and the piston 19 can squeeze the second spring 20. During this process, the milling cutter assembly 9 can be driven to move by the cylinder 7, and during the process of the milling cutter assembly 9 moving downward, the slider 14 can squeeze the first spring 12, and the piston 19 can squeeze the second spring 20, thereby further slowing down the speed at which the milling cutter assembly 9 moves downward, avoiding the milling cutter assembly 9 from moving downward too fast and colliding with the workpiece, thereby protecting the milling cutter assembly 9 and improving the practicality of the device.

[0025] The implementation principle of an anti-collision tool device for a CNC milling machine in an embodiment of the present application is as follows: the electrical components appearing in the present application are all externally connected to a power supply and a control switch when in use. When in use, the workpiece is placed on the base 1, and the mounting plate 8 can be driven to move downward by starting the cylinder 7, and the mounting plate 8 can drive the milling cutter assembly 9 thereon to move downward. When the milling cutter assembly 9 moves to an appropriate position, the workpiece can be processed, and the mounting plate 8 can drive the slider 14 to move and the connecting column 16 to move downward through the connecting assembly when moving downward. The movement of the slider 14 can squeeze the first spring 12, and the downward movement of the connecting column 16 can drive the piston 19 to move downward, and the piston 19 can squeeze the second spring 20. In this process, the milling cutter assembly 9 can be driven to move by the cylinder 7, and in the process of the milling cutter assembly 9 moving downward, the slider 14 can squeeze the first spring 12, and the piston 19 can squeeze the second spring 20, so that the speed of the milling cutter assembly 9 moving downward can be further slowed down to avoid the milling cutter assembly 9 moving downward too fast and colliding with the workpiece, thereby protecting the milling cutter assembly 9 and improving the practicality of the device.
