Equipped with a limiting slot；Three positioning surfaces of the blade are designed using right-angle surface, and blade side is equipped with screw thread process tooth, whole
Body uses rectangular parallelepiped structure；It is characterized in that, further include：The blade carried out positioning with the milling arbor by limiting slot.
Preferably, in a kind of above-mentioned Novel threaded milling cutter, the blade is provided with two locking holes, the milling arbor
It is provided with locking hole corresponding with the blade.The milling arbor is positioned with the blade by the double screw fastenings of locking hole.
Preferably, in a kind of above-mentioned Novel threaded milling cutter, the blade lengths are 3.5: 1 with width ratio, knife
Piece anterior angle forms 0 degree of anterior angle and 19 degree of relief angles using 19 degree of designs after being assembled with the milling arbor.
Preferably, in a kind of above-mentioned Novel threaded milling cutter, the screw thread process tooth is in the arrangement of comb property.
Preferably, in a kind of above-mentioned Novel threaded milling cutter, locking hole is suppressed by high-precision mold on the blade
Form.
It can be seen via above technical scheme that compared with prior art, the utility model milling arbor positioning surface is equipped with spacing
Slot structure, blade positioning face are designed using 90 ° of right-angle surfaces, so as to eliminate the side that traditional conical surface or inclined-plane add screw to position
Formula, position portion are limited in the situation that extreme case bottom knife flies out, protection screw will not be because of mistake using positioning method is faced directly
Carry and be broken, also using double screw fastening positioning, the coupling mechanism force than traditional single screw locking spot facing cutter carries for knife bar and blade in addition
Double the above；Longer blade can be installed, be applicable in longer screw thread process；With the characteristics of safe, vdiverse in function.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
The utility model embodiment is disclosed in a kind of safe, vdiverse in function Novel threaded milling cutter.
Please refer to Fig.1, Fig. 2, Fig. 3, Fig. 4 are a kind of safe, vdiverse in function novel spiral disclosed in the utility model
Line milling cutter.
Specifically include：A kind of Novel threaded milling cutter, including：Milling arbor 1, blade 2；The positioning surface of the milling arbor 1
For with right-angle surface, and it is equipped with a limiting slot 3；Three positioning surfaces of the blade 2 are designed using right-angle surface, 2 side of blade
