Abstract
The utility model discloses an index-able cemented carbide thread milling cutter which comprises a cutter body, a blade, a locating screw and a compressing screw, wherein the cutter body is provided with a blade groove, the blade is arranged inside the blade groove, center positions of two faces of the blade are respectively provided with a counter-bore, a locating screw hole is arranged in the middle of the blade groove, two ends of the blade groove are respectively provided with a compressing screw hole, the screw head of the locating screw is arranged inside the counter-hole of the blade, and a screw head of the compressing screw compresses the blade tightly. As the installing and clamping way of a traditional thread blade is substituted by the way of eccentric compression of a level head compressing screw and a taper locating screw, size of the blade is reduced, and the number of the blade is increased under the permission of the cutter body. Moreover, structure of the cutter can be compact and the purposes of reducing process gap, processing small-bore-diameter threads, lowering shock, and improving process quality of threads and process efficiency can be achieved.
Description
Technical field
The utility model relates to the cutter that a kind of milling machine is used, but relates in particular to a kind of transposition carbide alloy thread milling cutter.
Background technology
At present, but because the fixing of transposition screw cutter often adopts the screw in compression mode, blade size is bigger; When a plurality of blade of clamping, the milling cutter construction size is bigger, and is compact inadequately; When processing undersized screwed hole, cutter is limited can't to be used because of size is bigger than normal, and with a screws clamp; When blade size is big, reliable and stable inadequately.
Summary of the invention
But the purpose of the utility model provides a kind of transposition carbide alloy thread milling cutter with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises cutter hub, blade, dog screw and housing screw; Have insert groove on the said cutter hub, said blade places in the said insert groove, and the center of two faces of said blade is provided with counter sink; Centre at said insert groove has positioning screw hole; The two ends of said insert groove have the housing screw hole, and said dog screw and said positioning screw hole are through being threaded, and the head of screw of said dog screw places in the counter sink of said blade; Said housing screw and said housing screw hole are through being threaded, and the head of screw of said housing screw compresses said blade.
Particularly, between the counter sink on the said blade and the positioning screw hole of said insert groove 30 ° off-centre is arranged, its offset is 0.3mm; The height of said blade is 7.5mm, and width is 3.5mm, and length is 40mm.
The diameter of said cutter hub can be different according to practical application, and when the diameter of said cutter hub was 26mm, the insert groove of said cutter hub was four, was evenly distributed on the circumference of said cutter hub, and said blade is four, places respectively in four said insert grooves; When the diameter of said cutter hub was 40mm, the insert groove of said cutter hub was six, was evenly distributed on the circumference of said cutter hub, and said blade is six, placed respectively in six said insert grooves.
The beneficial effect of the utility model is:
The utility model changes traditional screwer sheet clamping mode into the tack housing screw and tapering dog screw off-centre compresses; Blade size is reduced; Thereby under the situation that cutter hub allows, increase knife number; Make cutter structure compact, reduce machining gap, can process the small-bore screw thread, reduce vibrations, improve the purpose of screw processing quality and working (machining) efficiency thereby reach.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like Fig. 1, Fig. 3, Fig. 4 and shown in Figure 5: the utility model comprises cutter hub 1, blade 2, dog screw 3 and housing screw 4; Have insert groove on the cutter hub 1, blade 2 places in the insert groove, and the center of 2 two faces of blade is provided with counter sink; Centre at insert groove has positioning screw hole; The two ends of insert groove have the housing screw hole, and dog screw 3 and positioning screw hole are through being threaded, and the head of screw of dog screw 3 places in the counter sink of blade 2; Housing screw 4 and housing screw hole are through being threaded, and the head of screw of housing screw 4 compresses blade 2.
As shown in Figure 5: between the counter sink on the blade 2 and the positioning screw hole of insert groove 30 ° off-centre is arranged, its offset is 0.3mm.
Like Fig. 3 and shown in Figure 4: the height of blade 2 is 7.5mm, and width is 3.5mm, and length is 40mm.
The diameter of cutter hub 1 can be different according to practical application, and as depicted in figs. 1 and 2: when the diameter of cutter hub 1 was 26mm, the insert groove of cutter hub 1 was four, was evenly distributed on the circumference of cutter hub 1, and blade 2 is four, places respectively in four insert grooves.
Like Fig. 6 and shown in Figure 7: when the diameter of cutter hub 1 was 40mm, the insert groove of cutter hub 1 was six, was evenly distributed on the circumference of cutter hub 1, and blade 2 is six, placed respectively in six insert grooves.
As shown in Figure 4: to the newly-designed mode that compresses; At first on blade 2, be designed with 60 ° counter sink; Be positioned at the central authorities of blade 2; Corresponding position (relevant position behind the blade of packing into) is provided with a positioning screw hole on the cutter hub 1 of screw cutter simultaneously, and it is 0.3mm that this counter sink and positioning screw hole have one 30 ° off-centre (α among Fig. 1) and the offset on 30 ° of directions, makes the top of dog screw contact (as shown in Figure 5) at eccentric direction with the blade counter sink.This offset has been arranged, just converted radially jackscrew spiral torsion into back axial power, blade 2 has been positioned at effectively on the inwall of screw cutter (D among Fig. 1, Fig. 2, Fig. 6 and Fig. 7, B two sides).Simultaneously a housing screw 4 is installed respectively, blade 2 is pressed in the inwall (the C face among Fig. 2 and Fig. 7) of screw cutter at the two ends of jackscrew.Thereby blade 2 is clamped reliably.
Because adopt the above-mentioned mode that compresses; The size of blade 2 reduces significantly; Can on blade 2, design multiple thread forming tooth, pitch can be designed to according to different demands simultaneously: 1.0 pitch are that 39 teeth, 1.5 pitch are that 26 teeth, 2.0 pitch are that 19 teeth, 2.5 pitch are 15 teeth, 3.0 pitch, 13 teeth.
