At this time, the side of the milling cutter 204 will be connected to the side of the positioning body 202, and finally they are connected and fixed by bolts. The purpose of setting the positioning block 201 and the positioning pin rod 203 is to fix the lower end of the milling cutter 204, which can effectively reduce the vibration of the milling cutter 204 during the cutting process, and on the other hand, it is convenient for subsequent disassembly and maintenance.

[0036] The blade fixing assembly 3 includes: a connecting seat 301, a waterproof sealing ring 305 and a waterproof screw 308. The connecting seat 301 is installed at the lower end of the central axis 1. A cooling water tank 4 is provided inside the connecting seat 301. The lower end surface of the cooling water tank 4 is provided with a second guide hole 302. A second groove 303 is provided on a lower end surface of the connecting seat 301.

At this time, the installation is completed. When the workpiece is cut, the coolant provided by the coolant system of the milling cutter machine tool enters the cooling water tank 4 of the milling cutter, and then the cooling water in the cooling water tank 4 passes through the third guide hole 307, the second guide hole 302, The cooling water flows out from the first guide hole 101, and finally flows out from the cooling water outlet 5 under the action of centrifugal force, and is sprayed onto the milling blade 204 and the surface of the workpiece for cooling as the cutter body rotates; the utility model realizes the reinforcement effect of the milling blade 204 through the positioning pin rod 203, effectively reduces the vibration generated when the workpiece is cut, ensures that the blade is in a relatively stable state during processing, and improves the availability and stability of the tool. By setting a cooling water trough 4, the cutter body can automatically reduce the surface temperature of the milling blade 204 by throwing out the coolant through the centrifugal force during the rotation of the cutter body. On the other hand, the waterproof screw 308 connects the connecting seat 301, the waterproof sealing ring 305, the positioning block 201, and the center axis 1 to realize the detachable effect of the cutter body. After the components of the cutter body itself are damaged, they can be repaired or replaced according to the corresponding components, reducing the cost of the workpiece and having a good market prospect.
