[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0026] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a kind of milling cutter for quickly processing the end face of rotary body, including cutter main body 1 and three-leaf cutting edge 2, cutter main body 1 is overall cylindrical, is composed of large cylinder and small cylinder, it is equipped with inner hole 3 in cutter main body 1, three bosses 4 are provided on inner hole 3, the rest positions of inner hole 3 are two direction chip flutes 5, cutter guide block 6 is equipped on boss 4, mounting buckle 7 is equipped at the large cylinder end face of cutter main body 1, stop buckle 8 is equipped at the small cylinder axial surface of cutter main body 1, stop buckle 8 two are evenly distributed, three-leaf cutting edge 2 is installed along cutter guide block 6 in inner hole 3, three-leaf cutting edge 2 is fixed on boss 4 when installing, the lower end surface of three-leaf cutting edge 2 is cutting edge.
[0027] In the embodiment, the inner hole 3 of the cutter main body 1 is an irregular through hole. The irregular shape can better cooperate with other structures inside the cutter, such as the boss 4 and the chip flute 5, thereby providing a specific spatial layout for the installation of the three-leaf cutting edge 2. This makes the cutter main body 1 more compact and reasonable in overall structure, which helps to improve the stability and machining precision of the cutter main body 1.
[0028] In the embodiment, the inner hole 3 of the cutter main body 1 has two-directional horn mouth-shaped inclined surfaces. This design plays a key role in chip removal. The two-directional horn mouth inclined surfaces can guide the chips to be discharged more smoothly from the inside of the cutter. During the machining process, the chips generated will be guided along the horn mouth inclined surfaces and quickly enter the chip flute 5, greatly improving the chip removal efficiency and preventing the chips from accumulating and clogging inside the cutter, thereby ensuring the continuity and precision of the machining.
[0029] In this embodiment, the surface of the tool guide block 6 of the tool body 1 is arc-shaped. When machining the end face of a rotary body, the arc-shaped design of the guide block 6 can effectively adapt to the shape change of the workpiece surface. When the tool body 1 is used to machine an electrode cap or other rotary body workpiece, the guide block 6 can provide stable support and guidance for the electrode cap, avoiding the phenomenon of jumping or stabbing the tool during machining, ensuring the smoothness of the machining process, and also providing stable support for the three-leaf cutting edge 2, enhancing the strength of the blade and prolonging the service life of the blade.
[0030] In this embodiment, the shape of the stop buckle 8 of the tool body 1 can be adjusted according to the existing equipment. Different machining equipment may have differences in tool installation and fixing methods. The adjustable shape of the stop buckle 8 can make the tool better adapt to various equipment. By changing the shape of the stop buckle 8, it can be ensured that the tool body 1 can be firmly installed on different equipment, ensuring that the tool body 1 does not displace or loosen during machining, thereby ensuring machining accuracy.
[0031] In this embodiment, the rake angle of the three-leaf cutting edge 2 is 5°, the relief angle is 7°, and the second relief angle is 23°. The rake angle of 5° helps to reduce cutting deformation and cutting force, making the cutting process more smooth, reducing tool wear, and improving the quality of the machined surface. The relief angle of 7° can reduce friction and wear between the tool relief surface and the machined surface of the workpiece, ensuring the stability of the tool during cutting. The second relief angle of 23° further reduces friction during cutting, reduces tool wear, significantly improves the service life of the tool, and maintains good cutting performance of the tool during long-term machining.
