Description
One, technical field:
The invention belongs to Machining Technology field, the method for milling of rounding inside and outside the aperture being specifically related to a kind of conical shell profiled holes on the surface.
Two, background technology:
Aircraft engine parts mostly is lopps, and numerous parts, in order to weight reduction, often devises on the surface of the housing and organizes profiled holes (through hole) more, and as shown in Figure 1, General Requirements rounding inside and outside its aperture, to strengthen part life.Traditional diamond-making technique adopts pincers worker one by one with after the manual thick rounding of file or polishing cutter, then with emery cloth or polishing wheel polishing.But the working (machining) efficiency of this method is low, labour intensity is large, quality is unstable.
Three, summary of the invention:
The present invention is in order to solve the weak point in above-mentioned background technology, the method for milling of rounding inside and outside the aperture that a kind of conical shell profiled holes is on the surface provided, it can be processed the aperture on housing part surface, particularly process for fillet inside and outside the aperture on the common shell piece surface such as conical, cylindrical, have that efficiency is high, labour intensity is low, stay-in-grade feature.
For achieving the above object, the technical solution used in the present invention is: the method for milling of rounding inside and outside the aperture of a kind of conical shell profiled holes on the surface, is characterized in that: described milling step is:
A. first can the fraise jig of calibration be installed on the workbench of vertical CNC machine center with three axes, and centering fixture, then part is loaded fixture, and clamping platen, make part be fixed on the rotating disk of fixture, this fixture makes part outer cone surface level, calibration;
B. drill bit, general slotting cutter, T-shaped slotting cutter are being installed in the tool magazine of vertical CNC machine center with three axes, and by the ball tool setting on fixture;
C. call corresponding numerical control program, can carry out holing, hole milling, the operation of fillet inside fillet, milling outside milling, just can complete the processing of the rounding inside and outside milling aperture;
When d. often processing first group of hole and rounding, pull up alignment pin, rotate rotating disk, again plug alignment pin, fixture calibration can be made once, thus second group of hole and rounding can be processed, repeat above step, until process all apertures fillet.
Compared with prior art, the advantage that has of the present invention and effect as follows:
A. the aperture on housing part surface can be processed, particularly to the processing of the common shell such as conical, cylindrical, and have that working (machining) efficiency is high, labour intensity is low, stay-in-grade feature;
B. during milling fillet, only have corner R cutting edge portion and the feature contacts of cutter, thus contact area rate week is little when sword cuts, so cutting force is also little, good heat dissipation, tool wear are little, the life-span is long, cutting speed is high.

Five, detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
See Fig. 1-Figure 13: the method for milling of rounding inside and outside the aperture of a kind of conical shell profiled holes on the surface: described milling step is:
A. first can the fraise jig of calibration be installed on the workbench of vertical CNC machine center with three axes, and centering fixture, as shown in Figure 2, then part is loaded fixture, and clamping platen 3, part is fixed on the rotating disk 5 of fixture.The effect of this fixture has 2 points: one is to make part outer cone surface level; Two is can calibration;
B. drill bit, general slotting cutter, T-shaped slotting cutter are installed in the tool magazine of vertical CNC machine center with three axes, and by ball 4 tool setting on fixture, as shown in Figure 2.
C. call corresponding numerical control program, can carry out holing, hole milling, the operation of fillet inside fillet, milling outside milling, just can complete the processing of the rounding inside and outside milling aperture.
D. as shown in Figure 2, when often processing first group of hole and rounding, alignment pin 2 is pulled up, rotate rotating disk 5, again plug alignment pin 2, fixture calibration can be made once, thus can second group of hole and rounding on processing parts, repeat above step, until process all apertures fillet.
The feature of described T-shaped slotting cutter is: with the R angle of upper and lower 2 groups of evaginations, as shown in Figure 3, and the maximum gauge of cutter must be less than the minimum diameter of profiled holes, not interfere with part.
The principle of T-shaped slotting cutter milling aperture fillet: (with interior survey outside the milling time-division)
A., outside milled part during fillet, with the R cutting edge milling below T-shaped slotting cutter, as shown in Figure 8, T-shaped slotting cutter, according to the tool path of shape (as Fig. 4,5,6,7) Suo Shi, just can complete milling;
B., inside milled part during fillet, T-shaped slotting cutter needs to be deep in hole, and with the R cutting edge milling above T-shaped slotting cutter, as shown in figure 13, T-shaped slotting cutter, according to the tool path of shape (as Fig. 9,10,11,12) Suo Shi, just can complete milling.
Outside milling, the generation way of the numerical control program of inner side fillet: such as, in UG software, the three-dimensional digital model of part is first carried out according to part Working position, as shown in the part 1 in Fig. 2, setting the outline data of T-shaped slotting cutter (shown in Fig. 3), as the maximum gauge value of cutter, up and down cutting edge R value etc.Then use the method for " fixed axis Surface contour milling ", select and want one of milling circle fillet surface to be milling region, generate the process tool track (as shown in FIG. 4,5,6, 7) of bull nose and the process tool track (as shown in Fig. 9,10,11,12) of filleted corner respectively, just can generate corresponding numerical control program by the post-processing function in software again, just can import lathe into by master datas such as amendment advance and retreat cuttves.
Such as: when milling of materials is the part of No. 45 steel, require rounding R1.5, (model: HS214 is carried out at general three axis machining center, Taiwan produces, digital control system: FAUNCSerise0i-MC), be that (upper and lower cutting edge R value is 1.5mm for the T-shaped slotting cutter of Ф 13mm with maximum gauge, material is carbide alloy, trade mark YT15, Zhuzhou diamond cutter company of producer), cutting speed can reach 80m/min, feed speed can reach 300mm/min.
