[0002] With the rapid development of modern manufacturing industry, CNC machine tools, especially vertical machining centers, have become indispensable core equipment in the field of metal processing. Vertical machining centers are widely used in aerospace, automobile manufacturing, mold processing, precision machinery and other industries with their remarkable characteristics of high precision, high efficiency and high flexibility. It fixes the workpiece on the workbench and uses the vertically arranged spindle and various tools installed on it to perform milling, drilling, tapping and other processing operations on the workpiece, which greatly improves the processing efficiency and processing quality. As an important part of the vertical machining center, the tool library plays a key role in automatically managing, storing and replacing tools. Modern tool libraries are exquisitely designed and can store a large number of different types of tools. Through the automatic tool changer, tools can be quickly and accurately replaced without manual intervention, which significantly improves the processing efficiency and reduces downtime. The design of the tool library is not only related to the overall layout and processing efficiency of the machine tool, but also directly affects the processing accuracy and maintenance cost of the machine tool. Although the existing vertical machining center and its tool magazine technology have made significant progress, there is still a problem that needs to be solved in practical applications, especially in the high-speed and high-intensity milling process of metal workpieces: improper treatment of tool surface residues; Specifically, after the milling cutter completes the milling process of the workpiece, coolant needs to be sprayed during the processing to reduce the temperature of the tool and the workpiece to prevent tool wear and workpiece deformation caused by overheating. Therefore, after the tool is replaced, the residual coolant and metal debris are often stored in the tool library together with the tool. Long-term accumulation will not only pollute the tool library, but also shorten the service life of the tool and increase maintenance costs.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0022] When in use, the air pipe 15 is connected to the external drying hot air blower, and the cutter sleeve 74 is used to store the milling cutter 8. When the milling cutter 8 needs to be replaced, the main control system is used to start the motor 61, and the output end of the motor 61 is used to drive the turntable 63 to rotate through the connecting rod 62. The rotation of the turntable 63 can prompt the slide post 65 to make a circumferential movement until the slide post 65 slides to the inner cavity of the slide groove 67. At this time, the limit block 64 and the drive disk 66 are disengaged, and then the slide post 65 and the slide groove 67 that move along the circumferential direction cooperate to prompt the drive disk 66 to drive the support disk 5 to rotate. At the same time, due to the meshing of the first gear 9 and the second gear 72, the support The rotation of the disk 5 can cause the tool sleeve 74 to drive the milling cutter 8 to rotate under the cooperation between the first gear 9 and the second gear 72, until the slide column 65 moves out of the inner cavity of the slide groove 67, at this time, the limit block 64 and the drive disk 66 are in a meshing state, so as to position the drive disk 66, when the output end of the motor 61 drives the turntable 63 to rotate one circle, a tool sleeve 74 can be switched to correspond to the position of the tool changing slot 3, and the above actions are repeated until the appropriate tool sleeve 74 is switched to correspond to the position of the tool changing slot 3, and the cylinder 10 is started, and the cylinder 10 is used to push the push block 11 to move downward, and then the push block 11 can be used to push the tool sleeve 74 to move forward. The spring 73 is rotated and stretched to elastically deform until the knife sleeve 74 rotates 90 degrees, so that the knife can be changed. After the replaced milling cutter 8 is inserted into the inner cavity of the knife sleeve 74, the cylinder 10 is started to drive the push block 11 to move upward, and then the knife sleeve 74 can be pulled back to the initial position under the elastic force of the spring 73. The motor 61 is started and the above action is repeated to drive the support plate 5 to rotate. Since the first gear 9 and the second gear 72 are meshed, the rotation of the support plate 5 can cause the knife sleeve 74 to drive the milling cutter 8 to rotate under the cooperation between the first gear 9 and the second gear 72, so that the cleaning The sponge 16 comprehensively cleans the milling cutter 8 in a rotating state to prevent coolant and metal debris from adhering to the surface of the milling cutter 8. The device can not only automatically remove the coolant and metal debris attached to the milling cutter 8 and avoid their accumulation in the tool library, thereby significantly reducing the pollution of the tool library, extending the service life of the milling cutter 8 and various machine tool components, and reducing maintenance costs, but also improve the cleanliness of the processing environment, reduce the risk of wear and corrosion of machine tool components caused by residues, and thus enhance the stability and reliability of the entire processing system, providing more efficient and accurate processing solutions for industries with high precision requirements such as aerospace, automobile manufacturing, etc.
