Description
Technical field
The present invention relates to field of machining, specifically a kind of armature spindle mechanical processing technique.
Background technique
In mechanical processing process, usually armature spindle is processed with numerical control horizontal complex milling machine tool, processed
Need to carry out armature spindle part the processing operation of finish-milling helicla flute in journey, the common process of the prior art is using numerical control
Horizontal type milling composite machining center, such as Fig. 4, Fig. 5, shown in Fig. 6, in the long layered cutting processing of cutter axis orientation knife, from helicla flute
Top starts to bottom to terminate.When this method processes special difficult to machine material, cutting edge access times are most at point of a knife,
Tool wear is caused, causes to process surface contour error increasing, process time is longer.
Summary of the invention
In view of the above-mentioned problems, this method is still sleeping using numerical control the present invention provides a kind of armature spindle mechanical processing technique
Formula turn-milling complex machining center, but in process, cutter remains unchanged carry out machining in the longitudinal direction, from spiral shell
The bottom of spin slot starts to top to terminate, and when processing to difficult-to-machine material, cutter different height cutting edge is only used once,
Tool wear is almost nil, causes processing surface contour error smaller, to propose high-profile precision, saves process time.
The technical solution that the present invention uses in order to solve the above problem: a kind of armature spindle mechanical processing technique, by armature spindle zero
Part is placed in numerical control horizontal complex milling machine tool, then uses numerical control horizontal complex milling machine tool by all jatharapanvartanasanas of armature spindle part
Shape machine-shaping, will be on the cutting edge and part of cutter before finish-milling starts when carrying out finish-milling helicla flute to armature spindle part
Helicla flute side bottom contact, the side of the helicla flute is the field of conjugate action of cutter and part, during finish-milling, cutter
It is remained unchanged in tool length direction, cutter is upwardly away from axis of workpiece direction offset coordinates in cutter diameter side, and zero
Part axis direction move back and forth, thus make cutter different height cutting edge respectively with engage face contact progress milling.
The present invention when carrying out finish-milling processing, the cutting edge of cutter different height respectively with engage face contact, to armature spindle into
Row milling, to prevent the cutting edge access times at tool nose from excessively causing tool wear and causing to process surface contour error mistake
Greatly.
Preferably, the armature spindle part (2) is in such a way that chuck (4) and top (5) are using one top of a folder by rotor
Axis part (2) is placed in numerical control horizontal complex milling machine tool.
Armature spindle can be fixed in numerical control horizontal complex milling machine tool using above-mentioned preferred embodiment, so as to armature spindle
It is machined.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawing and specific implementation
The present invention is described in detail for example.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
Such as Fig. 1, Fig. 2, Fig. 3, figure, shown in 7, Fig. 8, Fig. 9, a kind of armature spindle mechanical processing technique, by chuck 4 and top
5 are placed in armature spindle part 2 in numerical control horizontal complex milling machine tool by the way of one top of a folder, as shown in figure 3, then using number
Horizontal type turning and milling combined machine is controlled by all revolution shape machine-shapings of armature spindle part 2, finish-milling spiral shell is being carried out to armature spindle part
When spin slot, before finish-milling starts, the cutting edge of cutter 1 is contacted with the side bottom of the helicla flute on part 2, the side of helicla flute
Face is the field of conjugate action 3 that contacts with part 2 of cutting edge of cutter 1 as shown in fig. 7, during finish-milling, and cutter 1 is in tool length direction
On remain unchanged, cutter 1 is upwardly away from 2 axis direction offset coordinates of part in cutter diameter side, and past in 2 axis direction of part
Multiple mobile, variation such as Fig. 8 on the cutting edge of cutter 1 and the field of conjugate action 3 of part 2, shown in Fig. 9, from Fig. 7, Fig. 8, Fig. 9 be can see
The cutting edge of cutter different height contacts to carry out milling to part 2 respectively with the field of conjugate action 3 of part 2.
Armature spindle part 2 of the invention is by the chuck 4 and top 5 on numerical control horizontal complex milling machine tool using a folder one
Armature spindle part 2 is placed in numerical control horizontal complex milling machine tool by the mode on top, as shown in figure 3, then installing cutter 1, is used
Numerical control horizontal turn-milling complex machining center carries out armature spindle part 2 to rough mill helicla flute, and 1 axis of cutter is complete perpendicular to ruled surface
At roughing, all revolution shape machine-shapings of part 2 then, are subjected to finish-milling spiral with 1 shear blade machined part 2 of cutter
Slot, the present invention still uses numerical control horizontal turn-milling complex machining center to carry out finish-milling helicla flute to armature spindle part 2, in finish-milling spiral shell
Before spin slot, the side edge cutting edge of cutter 1 of the invention is contacted with the side bottom of the helicla flute on part 2, as shown in fig. 7, and
During cutter 1 processes part 2,1 motion process of cutter is to remain unchanged in the longitudinal direction, while cutter 1
It far from 2 axis direction offset coordinates of part in diametrical direction, and is moved back and forth in 2 axis direction of part, so that cutter 1
The cutting edge of different height contacts respectively at the field of conjugate action 3 and carries out milling, such as Fig. 8, shown in Fig. 9.And the finish-milling helicla flute of the prior art
Process, firstly, 1 side edge cutting edge of cutter is contacted with the side top of the helicla flute on part 2, as shown in figure 4, existing simultaneously
Layered cutting processing is carried out on length direction, so that point of a knife is commonly used in cutter 1 during carrying out finish-milling helicla flute
Locate cutting edge, as shown in Fig. 4, Fig. 5, Fig. 6.Therefore, compared with the prior art, the present invention carries out finely to unmanageable material
When helicla flute, the cutting edge of 1 different height of cutter is contacted respectively at the field of conjugate action 3 carries out milling, is carrying out essence compared with the existing technology
Commonly using cutting edge at point of a knife during milling spiral chute, the abrasion of cutter 1 can be reduced, reduces processing surface contour error, thus
High-profile precision is proposed, process time is saved.In the present embodiment, the part process in the early period of finish-milling helicla flute is ability
Therefore the common means of field technique personnel no longer carry out detailed herein in the part process of the early period of finish-milling helicla flute
Elaboration.
