Description
Technical field
It the utility model is related to wire rod quality field, more specifically a kind of multiple-cutting-edge disk milling with novel positioning structure
Knife.
Background technology
The positioning generally use contour localization of milling cutter and broached-tooth design positioning in the prior art, milling when using contour localization
Knife bottom surface is inclined-plane, is positioned using the inclined end face of milling cutter, and use broached-tooth design position when milling cutter bottom surface to face directly, milling cutter
Straight bottom surface be provided with broached-tooth design, and then positioned using the broached-tooth design on the straight bottom surface of milling cutter.Using both positioning
Circular runout of the milling cutter tolerance of mode on cutter influences big；In high rotating speed, the close tooth Milling Processes fed soon, due to
Frequently processing and vibrations, cutter is after a number of workpiece is processed, it is easy to loose phenomenon occurs, and then serious collapse occurs
Sword phenomenon, have a strong impact on machining accuracy and security.
The content of the invention
The purpose of this utility model is to provide a kind of multiple-cutting-edge wire rod quality with novel positioning structure, reduces milling cutter public affairs
Influence of the difference to cutter radial bounce, effectively increase the stability, machining accuracy and security of cutter.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of multiple-cutting-edge wire rod quality with novel positioning structure, including facing cutter, the facing cutter are uniform along outer circumference surface
Provided with multiple milling cutter grooves, a milling cutter is respectively and fixedly provided with each milling cutter groove, the milling cutter includes cutter hub and is fixed on cutter hub upper table
The blade in face, the blade are located at the front end of the cutter hub, and the lower surface of the cutter hub is inclined-plane, and the lower surface is provided with outer
Broached-tooth design, the highest point and lowest part of the outer broached-tooth design extend along the axis direction of the facing cutter, the milling cutter
The interior broached-tooth design being engaged with outer broached-tooth design is equipped with groove.
The outer broached-tooth design is evenly distributed on cutter hub lower surface, adds the frictional force of milling cutter and facing cutter, is reduced
The possibility that milling cutter flies out.
The lower surface of the cutter hub and rear surface angle are 75 ° ~ 85 °.
The blade is PCD blades.
The quantity of the milling cutter groove and milling cutter is 20 ~ 30.
The utility model is set along the extension of facing cutter axis direction by the way that milling cutter lower surface is set into inclined-plane in lower surface
Outer broached-tooth design, and the interior broached-tooth design being engaged with outer broached-tooth design is equipped with milling cutter groove, significantly reduce knife
The influence that piece tolerance is beated to cutter external diameter, and the stability of cutter in process is effectively increased, ensure machining accuracy,
Also ensure in milling process, together with milling cutter is brought into close contact with facing cutter, avoid milling cutter high rotating speed, high feeding it is processed
Occur serious tipping phenomenon in journey, improve security.

Embodiment
In conjunction with accompanying drawing, the utility model embodiment is described in detail：
As shown in Figures 1 to 5, a kind of multiple-cutting-edge wire rod quality with novel positioning structure, including facing cutter 1 and 24 milling cutters
2.Facing cutter 1 is uniformly provided with 24 milling cutter grooves 3 along outer circumference surface, and a milling cutter 2 is respectively and fixedly provided with each milling cutter groove 3.Milling cutter 2 wraps
Include cutter hub 4 and be fixed on the blade 5 of the upper surface of cutter hub 4, blade 5 is located at the front end of cutter hub 4, and blade 5 is PCD blades.Cutter hub 4
Lower surface 6 is inclined-plane, and lower surface 6 is 80 ° with the rear angle α of surface 7.The lower surface 6 of cutter hub 4 is provided with outer broached-tooth design 8, outer saw
Toothing 8 is evenly distributed on the lower surface 6 of cutter hub 4, adds the frictional force of milling cutter 2 and facing cutter 1, is reduced milling cutter 2 and is flown
The possibility gone out.The highest point 9 and lowest part 10 of outer broached-tooth design 8 extend along the axis direction of facing cutter 1, in milling cutter groove 3
It is equipped with the interior broached-tooth design 11 being engaged with outer broached-tooth design 8.
When specifically used, first milling cutter 2 is fitted into milling cutter groove 3 along the axial direction of facing cutter 1, makes the outer broached-tooth design 8 of milling cutter 2
It is engaged with the interior broached-tooth design 11 of milling cutter groove 3, then milling cutter 2 is fixed in milling cutter groove 3 by auxiliary block.Milling process
In, due to by the reaction force corresponding with cutting force, the outer broached-tooth design 8 of milling cutter 2 and the interior broached-tooth design 11 of milling cutter groove 3
It can be brought into close contact and together, effectively increase the stability of cutter in process, and avoid milling cutter 2 in high rotating speed, Gao Jin
Occur serious tipping phenomenon in the process given, be also avoided that the phenomenon that milling cutter 2 radially flies out because of vibrations,
Security is improved, adds cutter life.
