[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] like Figures 1 to 4 As shown, a disc-type honeycomb milling cutter with a chip removal function includes a tool rod 1, a clamping groove 13 is provided at one end of the tool rod 1, an outer wall of the other end of the tool rod 1 is provided with an external thread 7, a slide groove 2 is provided on the outer surface of the other end of the tool rod 1, a return spring 3 is fixed inside the slide groove 2, a connecting rod 4 is fixed to one end of the return spring 3, a clamping block 5 is fixed to the outer surface of the connecting rod 4, a fixing sleeve 11 is provided on the outer side of the tool rod 1, an inner wall of the fixing sleeve 11 is provided with an internal thread 12, and a clamping groove 6 is provided on the outer surface of the fixing sleeve 11. After the blade 10 is installed, the fixing sleeve 11 is installed to one end of the knife rod 1 through the external thread 7 and the internal thread 12, and one end of the blade 10 is pressed. After the fixing sleeve 11 is fixed to the bottom of the knife rod 1 through the external thread 7 and the internal thread 12, the elastic action of the return spring 13 drives the connecting rod 4 in the slide groove 2 to drive the clamping block 5 to clamp the clamping groove 6 on the fixing sleeve 11, so as to prevent the external thread 7 and the internal thread 12 from slipping after long-term use, so that the fixing sleeve 11 loses the pressure and fixation on the blade 10;

[0023] A cutter disc 8 is fixed to the top of the other end of the tool rod 1. A plurality of mounting grooves 9 are provided on the outer surface of the cutter disc 8. Blades 10 are provided inside the plurality of mounting grooves 9. A chip groove 24 is provided between two blades 10. Six blades 10 can be installed on the cutter disc 8 through the six mounting grooves 9. There is a chip groove 24 between the two blades 10 and the cutter disc 8. When processing honeycomb materials and fiber composite materials, the debris generated by the processing can be discharged through the chip groove 24. Example 2

[0024] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0025] The blade 10 forms a locking structure with the cutter disc 8 through the mounting groove 9, and the fixing sleeve 11 forms a threaded connection with the cutter bar 1 through the external thread 7 and the internal thread 12. The blade 10 is engaged with the cutter disc 8 so that when the blade 10 is installed on the cutter disc 8, there is a chip groove 24 between the blade 10 and the cutter disc 8. The chip groove 24 facilitates the discharge of debris generated by the processing when the honeycomb milling cutter processes honeycomb materials and fiber composite materials through the chip groove 24. The fixing sleeve 11 is installed to one end of the cutter bar 1 through the external thread 7 and the internal thread 12, pressing one end of the blade 10 to ensure a stable connection between the blade 10 and the cutter disc 8 while facilitating the replacement of a damaged blade 10.

[0026] A fixed head 14 is provided on the outside of one end of the tool rod 1 , and a mounting hole 15 is opened at one end of the fixed head 14 . The disc-type honeycomb milling cutter can be mounted on the fixed head 14 of the machine tool through the mounting hole 15 .

[0027] A return spring 2 16 is fixed to the inner wall of the fixed head 14, and a spring plate 17 is fixed to one end of the return spring 2 16, and a clamping plate 18 is fixed to the outside of the spring plate 17. When the clamping block 22 clamps the clamping groove 13, the spring plate 17 and the clamping plate 18 are elastically acted upon by the return spring 2 16, so that the clamping plate 18 is clamped above the connecting plate 20, thereby fixing the position of the clamping block 22. The tool rod 1 can also be pushed so that one end of the tool rod 1 is pushed against the spring plate 17, so that the spring plate 17 is retracted toward one end of the fixed head 14 through the return spring 2 16, so that the clamping plate 18 loses contact with the connecting plate 20, and then the clamping block 22 rebounds and loses its clamping of the tool rod 1, so as to facilitate the loading and unloading of the disc-type honeycomb milling cutter.

[0028] A moving groove 19 is provided inside the fixed head 14 , and a return spring 3 21 is fixed inside the moving groove 19 . The moving groove 19 and the return spring 3 21 enable the connecting plate 1 20 and the connecting plate 2 to move in the moving groove 19 .

[0029] One end of the return spring three 21 is fixed with a connecting plate one 20, and one end of the connecting plate one 20 is fixed with a clamping block 22, which can facilitate clamping the tool rod 1.

[0030] A connecting plate 2 is fixed to one side of the clamping block 22 , and a pressing block 23 is fixed to one end of the clamping block 22 . The pressing block 23 can be used to press the clamping block 22 to clamp the tool rod 1 .

[0031] Working principle: Before using the disc honeycomb milling cutter, install the six blades 10 on the cutter head 8 through the mounting groove 9, so that there is a chip groove 24 between the two blades 10 and the cutter head 8. When processing honeycomb materials and fiber composite materials, the chips generated by the processing are discharged through the chip groove 24. After the blades 10 are installed, the fixing sleeve 11 is installed to one end of the tool rod 1 through the external thread 7 and the internal thread 12, and one end of the blade 10 is pressed. After the fixing sleeve 11 is fixed to the bottom of the tool rod 1 through the external thread 7 and the internal thread 12, the connecting rod inside the slide groove 2 is driven by the elastic action of the reset spring 3. 4 drives the clamping block 5 to clamp the clamping groove 6 on the fixing sleeve 11 to prevent the external thread 7 and the internal thread 12 from slipping after long-term use, so that the fixing sleeve 11 loses the pressure and fixation on the blade 10. After the blade 10 is fixed, the knife rod 1 and the knife head are installed into the fixing head 14 through the mounting hole 15. The pressing block 23 is pressed, and the connecting plate 1 20 drives the clamping block 22 to move in the moving groove 19 through the return spring 3 21. When the clamping block 22 clamps the clamping groove 13, the spring plate 17 and the clamping plate 18 are clamped above the connecting plate 1 20 by the elastic action of the return spring 2 16, thereby fixing the position of the clamping block 22.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
