The present utility model provides a milling cutter structure for processing carbon fiber composite materials. The cutting portion is designed with four peripheral blades and end blades. Each peripheral blade is composed of multiple spiral cutting edges. When cutting at the same position, more cutting edges participate in the cutting. The spiral cutting edges have multiple chip breakers, forming a composite staggered tooth structure, making the chips more fragmented and easier to discharge. The cutting edges cut in the left and right helical directions, resulting in better processing effects. This effectively solves the problems of delamination, tearing, wire drawing, burrs, edge collapse, and tool edge collapse that are prone to occur during the processing of carbon fiber composite materials.

A rotating structure is formed between the support shaft 503 and the connecting groove 4, and a sliding structure is formed between the sleeve 501 and the penetration rod 504. A limit plate 6 is fixed on one end of the penetration rod 504 that penetrates into the sleeve 501, and a spring 7 is embedded on one side of the limit plate 6; the sleeve 501 is supported by the rotation of the insertion plate 502 and the support shaft 503, so that the angle of the sleeve 501 can be adjusted, and at the same time, the penetration rod 504 slides along the sleeve 501, which can automatically adjust according to the drilling position of the milling cutter to improve the stability of the support. At the same time, the universal ball seat 505 and the mounting cylinder 506 are used to avoid the limit affecting the stability during automatic adjustment, and the resistance ball 507 allows the mounting cylinder 506 to slide on the object to avoid excessive friction affecting the stability. The limiting plate 6 prevents the penetration rod 504 from disengaging, and the spring 7 facilitates the stable sliding of the penetration rod 504 to avoid shaking. Example 2

[0023] In addition to all the technical features of Example 1, this embodiment also includes: a positioning block 8 is fixed to one end of the outer wall of the knife rod 1 located inside the collar 3, and a connecting mechanism 9 is provided on one side of the positioning block 8. The connecting mechanism 9 includes a rotating ring 901, and the rotating ring 901 is rotatably connected between the collar 3 and the knife rod 1. A positioning groove 902 is provided at the top of the rotating ring 901 corresponding to the position of the positioning block 8, and an insertion groove 904 is provided at the position of the inner wall of the collar 3 corresponding to the rotating ring 901.

The outer wall of the collar 3 is connected to the groove 4 and the support shaft 503, so that the insert plate 502 drives the sleeve 501 to rotate, and the support angle is adjusted by the depth of the milling cutter drilling. At the same time, the penetrating rod 504 inside the sleeve 501 automatically adjusts the height according to the position of the milling cutter and cooperates with the universal ball seat 505 to avoid limit or conflict. The universal ball seat 505 is movably embedded in the installation tube 506. The contact ball 507 can rotate with the ring 3, and the penetration rod 504 is limited by the limit plate 6 to prevent it from disengaging. At the same time, it can automatically reset after clamping through the elastic push of the spring 7. The positioning block 8 fixed on the knife rod 1 penetrates the positioning groove 902 of the rotating ring 901 for interference, which makes it convenient for the knife rod 1 to interfere with the rotating ring 901, allowing the cutter head 2 to enter the object, and forms a ball bearing along the insertion groove 904 and the ball 905 through the connecting ring 903 to maintain the smoothness of the rotation process.
