[0030] Working principle:

[0031] When the present invention is used, the cutter head of the CNC machine tool is moved to the tool magazine. Initially, the first tool-changing groove 8 and the second tool-changing groove 12 are connected, so that the cutter head can enter the protective frame 5 normally, so that the blade 4 on the cutter head enters the tool holder 3. The cutter head 1 controls the rotation of the rotating disk 2 to drive the plurality of tool holders 3 to rotate, thereby driving the plurality of blades 4 to rotate, so that the new blade 4 in the tool magazine is located on the same axis as the cutter head. The cutter head is moved so that the cutter head and the blade 4 are connected together, thereby completing the replacement of the cutter head blade 4. When the cutter head is replaced, the motor 10 is started, and the transmission shaft of the motor 10 drives the second protective disk 11 to rotate, so that the first tool-changing groove 8 is sealed by the second protective disk 11. The protective frame 5, the first protective disk 7 and the second protective disk 11 are used to protect the blade 4 in the tool magazine, which can prevent the blade 4 from being damaged by external impact. At the same time, the probability of dust and iron filings adhering to the surface of the blade 4 in the tool magazine can be reduced, thereby avoiding the cutter head and the blade 4 from being damaged. The blockage at the connection of the blade 4 affects the tool changing efficiency of the cutter head. When the cutter head needs to change the tool again, the motor 10 drives the second protective disk 11 to rotate, so that the first tool changing groove 8 and the second tool changing groove 12 are connected. At this time, the cutter head can enter the protective frame 5 normally, so that the first protective disk 7 and the second protective disk 11 will not affect the tool changing efficiency of the cutter head. The protective box 9 is convenient for protecting the motor 10, and the heat sink 16 is convenient for improving the heat dissipation efficiency of the motor 10, thereby increasing the service life of the motor 10, thereby increasing the service life of the device. The battery 13 is convenient for providing power to the motor 10, without the need for additional laying of lines, reducing the probability of the line affecting the movement of the cutter head, so that the device is convenient for protecting the blade 4 in the tool magazine, reducing the probability of damage to the blade 4 in the tool magazine or adhesion of dust and iron filings, and will not affect the automatic tool changing of the cutter head, which is convenient for saving time and manpower and improving the tool changing efficiency of the cutter head.
