[0019] In actual application, the functional blade 2 is mounted by adapting with the first mounting joint surface 6 on the cutter body 1 through the second mounting joint surface 8, and after the second positioning bevel 9 is positioned and matched with the first positioning bevel 7, the functional blade 2 is locked on the cutter body 1 through the locking piece 19. According to the actual milling function requirements, functional blades 2 with different cutting edges 10 can be installed on the cutter body 1, so that one cutter body 1 can be used with functional blades 2 with different cutting edges 10 to become a machine-clamped milling cutter with different functions (for example: square shoulder milling cutter, round nose profiling milling cutter, fast feed milling cutter, etc.). One cutter body 1 of the utility model can be installed with functional blades 2 with different cutting edges 10, which reduces the number of cutter bodies 1 and reduces the cost of production and use. Moreover, it only needs to replace the functional blades 2 with different cutting edges 10 to become a machine-clamped milling cutter with different functions, which greatly reduces the labor intensity and saves the time of disassembly and replacement.

[0020] In this embodiment, an axial hole 11 is arranged in the axial direction of the handle 3, and a plurality of radial holes 12 are arranged in the radial direction of the cutter head 4. The inner ends of the plurality of radial holes 12 are connected with one end of the axial hole 11. The cutter head 4 is provided with a plurality of inclined channels 13 in a ring array. The plurality of inclined channels 13 are respectively arranged in one-to-one correspondence with the plurality of mounting grooves 5. The inclined channels 13 face the functional blades 2 in the mounting grooves 5. A main channel 14 is arranged at the corner of the mounting groove 5. One end of the inclined channel 13 is connected with the radial hole 12, and the other end of the inclined channel 13 is connected with the main channel 14. A plurality of branch channels 15 are arranged at the corners of the mounting groove 5, and the plurality of branch channels 15 are all connected with the main channel 14. In actual application, the coolant passes through the axial hole 11 into the radial hole 12, and then passes through the radial hole 12 into the inclined channel 13. The inclined channel 13 sprays a part of the coolant directly onto the functional blade 2, and the other part of the coolant passes into the main channel 14. The main channel 14 diverts the coolant into multiple branch channels 15. The coolant in the branch channel 15 passes through the functional blade 2 to cool the functional blade 2.

[0021] In this embodiment, the inclination angle of the first positioning inclined surface 7 is 3°; this structural design facilitates the installation of the functional blade 2.

[0022] Specifically, the diameter of the cutter body 1 ranges from 12 mm to 400 mm. According to the diameter of the cutter body 1 , the number of functional blades 2 installed is 1 to 40.

[0023] In this embodiment, the outer end of the radial hole 12 extends to the side wall of the cutter head 4, and a sealing plug 16 is detachably mounted on the outer end of the radial hole 12. This structural design facilitates the processing and forming of the radial hole 12, and the sealing plug 16 blocks the outer end of the radial hole 12, has a good sealing effect, and prevents leakage of the coolant.

[0024] In this embodiment, the bottom wall of the mounting groove 5 is provided with a threaded hole 17, the threaded hole 17 is located in the middle of the first mounting joint surface 6, the middle of the functional blade 2 is provided with a through hole 18, the through hole 18 is located in the middle of the second mounting joint surface 8, and the locking member 19 is a bolt, the stud of the bolt passes through the through hole 18 and is threadedly connected with the threaded hole 17. This structural design is conducive to firmly locking the functional blade 2 in the mounting groove 5 of the blade body 1.

[0025] In this embodiment, the top surface of the functional blade 2 is also provided with a second mounting joint surface 8, and the bottom surface corners of the functional blade 2 are also provided with blades 10, and the blades 10 at the top surface corners of the functional blade 2 are staggered with the blades 10 at the bottom surface corners of the functional blade 2. This structural design enables the front and back sides of the functional blade 2 or the front and back positions of the functional blade 2 to be installed in the mounting groove 5 of the blade body 1 for use, thereby improving the service life of the functional blade 2. Specifically, the diverter 15 can provide an escape space for the corresponding blade 10.

[0026] Specifically, the first mounting joint surface 6 is coated with a wear-resistant coating layer, and the thickness of the wear-resistant coating layer is 0.5 mm. This structural design increases the wear resistance of the first mounting joint surface 6 and is not easy to wear.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
