Description

A kind of diamond screw-on cutter

Technical field

The utility model is related to a kind of milling cutter, in particular it relates to a kind of diamond screw-on cutter.

Background technology

In the last few years, with the development of science and technology, requirement of the machinery manufacturing industry to machining accuracy is also more and more higher, milling cutter is made For one kind machining Common Use Tools, its structure not only decides the intensity of itself, service life, further determines and get out workpiece hole Error size and precision height.

In space flight, aviation, military project, automotive field, largely using composite, to processing the dimensional accuracy in aperture and bright and clean Degree requires higher, while technical requirements and service life more and more higher to process tool in itself, existing carbide-tipped milling cutter Although processing can meet means suitable, in process because abrasion is very fast, particularly to carbon fiber, silico-aluminum, It is poor using plain cutter processing finish when the high rigidity new material such as tungsten-copper alloy is processed, cause the aperture chi of product Very little uniformity is not good, and fraction defective is higher, and the product service life processed is longer.Further, since existing milling cutter construction design It is unreasonable, influence the intensity and service life of itself.

Utility model content

The purpose of this utility model is to provide a kind of diamond screw-on cutter, to solve what is proposed in above-mentioned background technology Problem.

To achieve the above object, the utility model provides following technical scheme：A kind of diamond screw-on cutter, including spiral Cutter body, the screw-on cutter body includes handle of a knife, the knife bar for being connected to described handle of a knife one end, the bottom located at knife bar front end Sword, the knife bar includes bar core, circumference sword, and the handle of a knife, knife bar, shear blade are along same central axis rotary work, the knife bar Provided with the helicla flute for chip removal, the helicla flute is that, from shear blade to 4 roads of handle of a knife directional smoothing transition, the knife bar is glomerocryst Diamond, the knife bar is welded and fixed with the handle of a knife and is connected, and the circumference sword is 4 sword helical edges, the helicla flute court Handle of a knife direction is, to right-hand screw, the shear blade of milling cutter to be put upward and in terms of the front of milling cutter, circumference sword and shear blade when extending Cutting edge towards counterclockwise.

It is preferred that, the shear blade is from periphery to the micro, slight convexity in center, so as to can axially cut to a certain extent.

It is preferred that, the spiral angular region of the helical edges is 30 °~60 °.

It is preferred that, the helical angle is 35 °.This angle, makes milling cutter more steady when switching in and out, cutting resistance Fluctuation is small, reduces the comprehensive effect to factors such as the vibrational excitations of milling cutter in processing.

It is preferred that, the handle of a knife is cylindric staight shank, makes to be convenient to mount and dismount between handle of a knife and fixture.

It is preferred that, the bar core diameter is 10.4mm.

Compared with prior art, the beneficial effects of the utility model are：This diamond screw-on cutter makes full use of artificial gold The features such as hard rock glomerocryst hardness is high, coefficient of friction is small, thermal coefficient of expansion is small, thermal conductivity is high, storeroom affinity is small, passes through structure Curve guide impeller, makes screw-on cutter sectional area rate increase when carrying out side Milling Process, is rigidly improved, is conducive to reducing The bending of milling cutter, and cutting resistance change is small, tool stiffness is big, is difficult flexural deformation, and the surface quality of machined surface is high, has The features such as chip is steady, easy to loading and unloading, applied widely, machining accuracy is high, greatly reduces production cost.

Fig. 2 is the cross-sectional view of the utility model embodiment knife bar；

Wherein：1. handle of a knife, 2. knife bars, 3. helicla flutes, 4. circumference swords, 5. shear blades, 6. bar cores.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Shown in reference picture 1, Fig. 2, a kind of diamond screw-on cutter, including screw-on cutter body, the screw-on cutter body Including handle of a knife 1, the knife bar 2 for being connected to described one end of handle of a knife 1, the shear blade 5 located at the front end of knife bar 2, the knife bar 2 include bar core 6, Circumference sword 4, the handle of a knife 1, knife bar 2, shear blade 5 are provided with the spiral shell for chip removal along same central axis rotary work, the knife bar 2 Spin slot 3, the chip area is from shear blade 5 to the directional smoothing transition of handle of a knife 1, and the knife bar 2 is polycrystalline diamond material, the knife bar 2 are welded and fixed with the handle of a knife 1 and are connected, and the circumference sword 4 is 4 swords, the helicla flute 3 towards the direction of handle of a knife 1 extend when be to the right Spiral, the shear blade 5 of milling cutter is put upward and in terms of the front of milling cutter, the cutting edge of cutting edge is towards counterclockwise.It is described Shear blade 5 is from periphery to the micro, slight convexity in center, so as to can axially cut to a certain extent.The helical angle is 35 °.The handle of a knife 1 For cylindric staight shank, make to be convenient to mount and dismount between handle of a knife 1 and fixture.

In a diameter of 10.4mm of bar core, the results showed, the diamond screw-on cutter of the utility model embodiment reaches To the same size common 50-100 times of life-span of wolfram steel milling cutter, tool changing, toolsetting are effectively reduced, to work such as knives；Processing finish can be with Ra0.2-0.4 or so is reached, can disposably replace tradition to rough mill, finish-milling, multiple complicated procedures of forming such as polishing, highly reduction production Cost.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
