An external robotic arm is used to pass the CNC tool body 13 through the inner cavity of the hollow square frame 23 for storage. Before storage, the solenoid valve 25 is controlled to open to transport the gas inside the gas cylinder 21 to the hollow square frame 23, and the gas is then output from the inclined air nozzle 24 to clean up the debris attached to the outer surface of the CNC tool body 13 to ensure the safety of the CNC tool body 13.

[0024] As an implementation method in this embodiment, Figure 3 As shown, an air pump 27 is fixedly installed on the back of the air cartridge 21, and the output end of the air pump 27 is fixedly connected to the back of the air cartridge 21, and the input end of the air pump 27 is detachably connected to a filter cartridge 272, and a digital pressure gauge 271 is fixedly connected to the back of the air cartridge 21. The air pump 27 and the digital pressure gauge 271 are connected through an external control electrical signal to control the operation of the air pump 27, so that air can be inflated into the inner cavity of the air cartridge 21 to facilitate the air blowing and cleaning work. The model of the digital pressure gauge 271 can be YK-100B. During the operation of the air pump 27, the air pressure in the inner cavity of the air cartridge 21 is monitored by the digital pressure gauge 271. After the air pressure reaches a preset value, the air pump 27 is controlled to stop working to ensure the overall safety of the air cartridge 21. At the same time, through the design of the filter cartridge 272, the gas absorbed by the air pump 27 can be filtered.

[0025] As an implementation method in this embodiment, Figure 4 , Figure 5 and Figure 6As shown, the tool body protection mechanism 2 also includes a cross bar 28 and a support frame 29. The cross bar 28 is welded on both sides of the tool magazine body 1. A sliding sleeve 281 is slidably connected to the outer wall of the cross bar 28. A connecting rod 282 is fixedly connected to the front of the sliding sleeve 281. An L-shaped protective plate 283 is fixedly installed at one end of the connecting rod 282 away from the sliding sleeve 281. A rubber strip 284 is fixedly connected to the front of the L-shaped protective plate 283. A rubber plate 285 is fixedly connected to the front of the rubber strip 284. The support frame 29 is fixedly installed at the bottom of the tool magazine body 1. A bidirectional screw rod 291 is rotatably connected between the two sides of the inner wall of the support frame 29. A servo motor 293 is fixedly installed on the right side of the support frame 29. The output shaft of the servo motor 293 is fixedly connected to the right end of the bidirectional screw rod 291.

The servo motor 293 is controlled to work, which can drive the bidirectional screw rod 291 to rotate, prompting the two sliding blocks 292 to move toward each other. The transmission of the transmission rod 294 synchronously drives the two L-shaped protective plates 283 to move toward each other, and then the front side of the tool magazine body 1 is shielded and protected by the L-shaped protective plate 283 to avoid the problem that the splashing debris will cause damage to the tool magazine body 1 as a whole. When the L-shaped protective plate 283 moves, the sliding sleeve 281 can slide on the outer wall of the cross bar 28 to improve the stability of the movement of the L-shaped protective plate 283. Both the rubber strip 284 and the rubber plate 285 can produce elastic deformation to buffer the force of the debris hitting the L-shaped protective plate 283, thereby ensuring the safety of the L-shaped protective plate 283.

[0026] Working principle: the air pump 27 is controlled in advance to pre-store gas in the air storage cylinder 21. When in use, the CNC tool body 13 is passed through the inner cavity of the hollow square frame 23 for storage with the help of an external robotic arm. Before storage, the solenoid valve 25 is controlled to open to transport the gas inside the air storage cylinder 21 to the hollow square frame 23. The gas will then be output from the inclined air nozzle 24 to clean up the debris attached to the outer surface of the CNC tool body 13, thereby ensuring the safety of the tool magazine body 1 and the CNC tool body 13.
