The purpose of this utility model is in view of the above problems, providing a kind of milling cutter group for pliers mill hole Milling Process Part, the ingenious processing that opposite grinding disk hole is realized using milling cutter construction of energy, in addition using similar triangular design, most to save cutter material Mode, realize side wall and bottom surface simultaneous processing, vibration is few, low noise.

In order to achieve the above object, the technical solution adopted in the utility model is: one kind being used for pliers mill hole Milling Process Mill cutter assemblies, it includes tool bar and the milling cutter that is mounted below tool bar, empty in tool bar center, is mounted therein with pair Mandrel, the milling cutter be axially symmetric structure, long side and short side including square crossing, wherein all long sides cross into two-by-two it is equilateral Triangle；In the plane below tool bar, the short side of the milling cutter is in outside the circumference of tool bar for the long edge position of the milling cutter At diameter；The tool bar corresponding position is provided with milling cutter mounting groove, and milling cutter mounting groove is communicated with the centre bore of tool bar.

Further, the milling cutter is that long side length is equal with tool bar annulus cross section chord length.

Further, center roller upper end sidewall surfaces are provided with the escape groove of strip along axial direction, the escape groove Position is that milling cutter installs groove location.

Further, the escape groove runs through center roller both side surface by the diameter of center roller.

Further, the escape groove for avoiding milling cutter position, the evacuation are provided in the center roller sidewall surfaces Slot is helicla flute.

The utility model has the beneficial effects that the utility model provides a kind of milling cutter for pliers mill hole Milling Process Component, the ingenious processing that opposite grinding disk hole is realized using milling cutter construction of energy, in addition using similar triangular design, most to save cutter material The mode of material realizes side wall and bottom surface simultaneous processing, and vibration is few, low noise.

1, special-shaped equilateral triangle design is used, the just side wall to pliers mill hole and bottom under the form of most material saving Face Milling Process.

2, using specially designed escape groove, the part that milling cutter protrudes into center roller centre bore can be accommodated, is avoided to right Mandrel installation generates interference.

3, triangular-shaped blades design, the most saving material, and can with three times general exchanges, meanwhile, triangle is distinctive Stability avoids milling cutter offset.

4, it is designed using the utility model, side wall processing uses the cutting edge of symmetrical milling cutter, and bottom surface processing also uses pair The milling cutter cutting edge of title symmetrically counteracts most of unbalance dynamic power, so that processing is more steady.

Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model There is any restriction effect.

As shown in figures 3 to 6, a kind of specific structure of the utility model are as follows: milling cutter for pliers mill hole Milling Process Component, it includes tool bar 9 and the milling cutter 91 for being mounted on the lower section of tool bar 9, empty in 9 center of tool bar, is mounted therein with pair Mandrel 92, the milling cutter 91 are axially symmetric structure, long side 912 and short side 911 including square crossing, wherein all long sides 912 Equilateral triangle is crossed into two-by-two；The long edge position of the milling cutter is in the plane below tool bar 9, the short side of the milling cutter 911 Place is at the circumference outer diameter of tool bar 9；9 corresponding position of tool bar is provided with milling cutter mounting groove 901, and milling cutter mounting groove 901 communicate with the centre bore of tool bar 9.

Preferably, the length of the long side 912 of the milling cutter 91 is equal with 9 annulus cross section chord length of tool bar, referring specifically to Fig. 3, Fig. 5, Fig. 6.

Preferably, the 92 upper end sidewall surfaces of center roller are provided with the escape groove 921 of strip, the escape groove along axial direction 921 position is corresponding with 901 position of milling cutter mounting groove.

Preferably, the escape groove 921 passes through the diameter of center roller 92, runs through 92 both side surface of center roller.

It is the utility model another kind center roller structural schematic diagram referring to Fig. 8, it is preferred that 92 sidewall surfaces of center roller On be provided with escape groove 921 for avoiding 91 position of milling cutter, the escape groove 921 is helicla flute.It, can be in specific installation Center roller 92 is adjusted, makes to extend into 91 convex portion of milling cutter (S portion in such as Fig. 7) inside the centre bore of center roller 92, energy It is embedded just below in the escape groove 921 on 92 surface of center roller.

It is designed using the utility model, side wall processing uses the cutting edge of symmetrical milling cutter, and bottom surface processing also uses symmetrical Milling cutter cutting edge, symmetrically counteract most of unbalance dynamic power so that processing it is more steady.I.e. as shown in Fig. 3, Fig. 4, cutter It is symmetrical arranged two milling cutters 91 on bar 9, avoids and occurs described in Fig. 2 due to milling cutter discontinuity, only single milling cutter Stress be easy to cause unbalance dynamic, so as to cause processing vibration, the big problem of noise；It and is two symmetrical when milling side wall The short side 911 of milling cutter 91 is processed simultaneously, and when milling plane is the long side 912 of two milling cutters 91 while being processed, milling It is more efficient, monolithic milling cutter 91 is worn than before to be greatly reduced, and the service life of milling cutter 91 is extended, reduce maintenance replacement Cost.
