Abstract
The present invention provides a kind of numerical control profile milling cutters, mainly include cutter head, knife neck and knife handle, and the blade of cutter head is formed by four kinds of arc-shaped blades are tangent, and have certain centripetal angle.This cutter can process the chamfered area in part in place, eliminate processing residual, effect is particularly evident when processing the discontented R of part web bogging down area.
Description
Technical field
The invention belongs to field of machining, and in particular to a kind of multi-functional numerical control profile milling cutter, especially for part
Sharp edge rounding, downline zone chamfer machining.
Background technique
Numerically-controlled machine tool can be achieved automated production substantially at present, but with the enlargement of part, be thinning, structure is complicated changes
Development, common part base angle and sink for the conventional base angle such as R3 and R5, position can be machined directly to by numerically-controlled machine tool, but at present
Bogging down area chamfering, seamed edge rounding of discontented Zone R for occurring in part etc. become more diverse, and cause the position straight by lathe
It connects processing in place, then relies primarily on the manual reconditioning of pincers worker, not only heavy workload, but also influence product surface quality, it is serious to restrict
The development of lean numerical control.To comply with the development of Lean Manufacturing and the call without pincers worker polishing, a kind of multifunctional numerical control is thus designed
Profile milling cutter, the Efficient CNC machining for needing to realize part by the multifunctional numerical control profile milling cutter.
Summary of the invention
Present invention seek to address that the problem of mentioning in background technique, which passes through special more designed arc-shaped appearances, energy
The enough privileged sites processing by part in place, while avoiding the cut wound generated by manual operation process error or scale
A kind of numerical control profile milling cutter, it is characterised in that including cutter head, knife neck, knife handle, cutter head is containing there are four blade, each knives
Sword is made of the positive and negative tangent transition connection of Circular Nose Cutting Edge of four kinds of different curvatures, and the centripetal angle δ of the cutter head of four blades composition is
3 °~5 °.
It is an advantage of the present invention that arc radius R01, R02, R03 and R04 of four sections of different curvatures can be according to specific
The structure feature of part is designed, and the general value in the centripetal angle in bottom is 3 °~5 °, greatly weakens cutter during the cutting process
To adsorption capacity caused by part, product processing quality is further ensured.Due to the ad hoc meter at cutter head position, make it to operation
Factor, part form have well adapting to property, truly realize numerical control processing, ensure that product quality.
Detailed description of the invention
A kind of Fig. 1: multifunctional numerical control profile milling cutter overall structure figure of the present invention；
Fig. 2: tool bit part amplification assumption diagram in the present invention；
Fig. 3: in actual processing rounding schematic diagram in the present invention；
It numbers and illustrates in figure: 1. knife handles, 2. knife necks, 3. cutter heads, 4. parts to be processed, 5. studs, 6. first downset areas,
7. the second downset areas
Specific embodiment
With reference to the accompanying drawings and examples, invention is further described in detail, but embodiments of the present invention are unlimited
In this.
Referring to attached drawing 1-3, the multifunctional numerical control profile milling cutter of the application includes bottom cutter head 1, knife neck 2, knife handle 3, cutter head
1 position is formed by connecting by four kinds of different curvature Circular Nose Cutting Edges are tangent, and four arcs sword radius is respectively R01, R02, R03, R04.
R01, R02, R03 and R04 can be designed according to the structure feature of specific numerical control part, and the centripetal angle δ in bottom takes 3 °~5 °.
Fig. 3 example is a kind of numerical control processing of aircraft beam-like part, and the material of part to be processed 4 is aluminium alloy, at stud 5
Fillet R4-01 is 1mm, and 6 lower limit fillet R4-02 of the first downset areas of web is 1mm, 7 lower limit fillet of the second downset areas
R4-03 is no more than R5.Designing the CNC milling cutter tool bit diameter D1 is 25mm, and the long L1 of sword is 11.5mm, centripetal angle δ=3 °, circle
Arc cutter blade portion, R01=0.5mm, R02=1mm, R03=0.5mm, R04=5mm；Knife neck diameter D2=16mm, length L2=
55mm；Shank diameter D3=25mm, clamping length L3=50mm.It can be by stud beveler bogging down area circle using this kind of constructed milling cutter
Angle time processing in place, ensure that product quality
The above content is the further descriptions for combining specific legal person's preferred embodiment to be the present invention, convenient for being somebody's turn to do
Those skilled in the art can understand and apply the invention, and it cannot be said that specific implementation of the invention is confined to these says
It is bright.For the those of ordinary skill of the technical field belonging to the present invention, without departing from the inventive concept of the premise also
It is that can make several deduction or replace, without having to go through creative labor.Therefore, those skilled in the art are according to the present invention
Announcement, all should be within protection scope of the present invention to the simple modifications made of the present invention.
