Description
Technical field:
The present invention relates to machining tool technical field, relate to a kind of indexable steering nut facing cutter in particular.
Background technology:
Steering nut in steering generally has five procedure of processings, comprise milling flat, milling chamfering, skiving bar, bore apical pore and car internal thread, it is large that consumption is changed in the rear cancelling stocks of transposition blade wearing and tearing that China NC Machine uses at present simultaneously, again little by the probability used, cause the waste of huge cost, the processing that the blades how recycling these wearing and tearing are used in steering nut is the work highly studied.
Summary of the invention:
Object of the present invention is exactly propose improvement project for the problem that utilization rate after the cancelling stocks of existing Digit Control Machine Tool transposition blade is low, consider the processing technology of steering nut and the performance characteristics of transposition blade SPWH12408 blade, we devise indexable steering nut facing cutter and utilize cancelling stocks blade to carry out milling six faces of steering nut and the processing at four angles of falling.This design can recycle the transposition blade of wearing and tearing effectively, makes it to play larger economic benefit, effectively can save processing cost.
Technology solution of the present invention is as follows:
This indexable steering nut facing cutter, comprise steering nut, blade, cutter hub, trip bolt, each facing cutter is designed with the milling cutter tooth of 12 circumferential array, milling cutter tooth crest installs SPWH12408 side's blade, carry out the Milling Machining of six planes to steering nut and four chamferings respectively, milling cutter tooth crest is left screwed hole and is installed trip bolt.
Preferred as technique scheme, the number of facing cutter is two, and facing cutter is arranged symmetrically with.
Preferred as technique scheme, the material of cutter hub is 42CrMo.
Preferred as technique scheme, the cutting angle of blade is 11 °.
Preferred as technique scheme, inside eccentric 0.15 ~ 0.3mm during the trip bolt centre bore of the facing cutter that drills and reams.
Preferred as technique scheme, the height of the blade cut sword on facing cutter should higher than milling cutter tooth outer at least 1mm.
Beneficial effect of the present invention is: in conjunction with the processing method of steering nut and the performance of SPWH12408 side's blade, we devise indexable steering nut facing cutter, make the replacing of blade easier, and each basil of the side's of taking full advantage of blade, not only make the blade cost in steering nut processing reduce 2/3rds, more improve the working (machining) efficiency of steering nut.

Detailed description of the invention:
Embodiment: by particular specific embodiment, working of an invention mode is described below, those skilled in the art can understand other advantages of the present invention and effect easily by content disclosed in the present specification.
As shown in Figures 1 to 6, processing a steering nut 1 needs five processes, is respectively its six planes of processing 101, four bottom chamfer 102, rach slot 103, top through hole 104 and internal threads 105.And combine the reuse ratio that a large amount of SPWH12408 blade 2 on indexable Digit Control Machine Tool is extremely low after wearing and tearing are by cancelling stocks at present, the blade 2 that we can utilize these to wear and tear is for the processing of two procedures before steering nut 1, design a kind of indexable steering nut facing cutter, comprise steering nut 1, blade 2, cutter hub 3 and trip bolt 4, cutter hub 3 is designed with the milling cutter tooth of 12 circumferential array, milling cutter tooth crest installs blade 2, milling flat angle E between the cutting plane of blade 2 and perpendicular is 45 °, the plane 101 of the nose part 201 of blade 2 to steering nut 1 is utilized to process, milling chamfering F between adjustment blade 2 cutting plane and perpendicular is 30 °, the chamfer plane 102 of the blade part 202 of blade 2 to steering nut 1 is utilized to process, the top of cutter hub 3 has screwed hole and installs trip bolt 4 and be used for fastening blade 2.
As shown in Figures 2 and 3, because the plane of steering nut to be processed 1 and chamfering structure are symmetrical, in order to improve working (machining) efficiency, arrange two facing cutters to while steering nut 1 two ends process.
As shown in Figures 2 and 3, the material of the cutter hub 3 of facing cutter is 42CrMo.As the quenching degree that the material require high strength of cutter hub, high tenacity are become reconciled, and 42CrMo can meet above-mentioned requirements well, 42CrMo material is without obvious temper brittleness, and after fine finishining nitrogen treatment, have higher fatigue limit and anti-this impact capacities many, low-temperature impact toughness is good, is the material of outstanding milling cutter body.
As shown in Figure 5, the cutting angle H of blade 2 is designed to 11 °, large cutting angle can make blade bear less operating pressure, but too small cutting angle then may cause unstable machine cuts, in addition, when cutting speed is higher, the process heat produced can not be discharged from blade fully, cutter thus can be subject to very large thermal force.Take cutting angle to be that the cutter of 11 ° can reach best cutting effect, namely cutting force is little, and cutting edge is stablized, and weares and teares little.
As shown in Fig. 2, Fig. 3 and Fig. 6, in order to make trip bolt 4 can fastening cutter hub 3 and blade 2 better, drill and ream milling trip bolt 4 centre bore time inside eccentric 0.15 ~ 0.3mm.
As shown in Figure 6, the height of blade 2 cutting edge on cutter hub 3 should higher than milling cutter tooth outer at least 1mm.Mainly utilize the nose part 201 of blade 2 when carrying out six plane machinings to steering nut 1, so its nose part 201 must keep the elongation more certain than the milling cutter tooth outer of cutter hub 3, it is highly at least 1mm.
Described embodiment in order to illustrative the present invention, but not for limiting the present invention.Any those skilled in the art all without prejudice under spirit of the present invention and category, can modify to described embodiment, therefore the scope of the present invention, should listed by claim of the present invention.
