Description
Technical field:
The utility model relates to machining tool technical field, relates to a kind of indexable inverted cone degree helical end mills in particular.
Background technology:
Indexable helical end mill has higher cutting speed, and working (machining) efficiency is high, is widely used in mechanical processing industry, but taper indexable helical end mill there is no standard, without manufacturer production.Some large-scale workpieces of the enterprise such as shipbuilding, water power need to carry out the processing of inverted cone degree type face, and universal cutter processing difficulties, efficiency are low.How designing the slotting cutter that can carry out the processing of inverted cone degree type face is a problem demanding prompt solution.
Utility model content:
The purpose of this utility model is exactly the processing difficulties, the inefficient problem proposition improvement project that exist for existing universal cutter processing inverted cone degree type face, devise indexable inverted cone degree helical end mills, achieve time processing to be shaped, effectively improve the working (machining) efficiency in inverted cone degree type face.
Technology solution of the present utility model is as follows:
A kind of indexable inverted cone degree helical end mills, comprising: cutter hub, all teeth cutter blades, end tooth blade and trip bolt; Cutter hub afterbody is 30 ° of cones, cone big end surface opens screwed hole, cutter hub conical surface has six right hand helix cutting teeths, every bar cutting teeth is evenly equipped with seven all teeth cutter blades and an end tooth blade, all teeth cutter blades and end tooth blade are all standard side's blade, and all teeth cutter blades and end tooth blade are fixed on the spiral cutting tooth of cutter hub by trip bolt.
Preferred as technique scheme, the material of cutter hub is 42CrMo.
Preferred as technique scheme, insert groove lengthening handle slotting cutter processing.
Preferred as technique scheme, the blade relief of end tooth blade and all teeth cutter blades is all 11 °.
Preferred as technique scheme, the processing of end tooth insert design will exceed all teeth cutter blade 0.5mm.
Preferred as technique scheme, drill and ream trip bolt centre bore time inside eccentric 0.15 ~ 0.3mm.
The beneficial effects of the utility model are: indexable inverted cone degree helical end mills structure of the present utility model is simple, be convenient to processing, all teeth cutter blades and end tooth blade shaft are convenient to tool changing to being distributed on cutter hub surface, all teeth cutter blades and end tooth blade adopt different specifications effectively can improve working (machining) efficiency, and the utility model is applicable to machining large workpiece angle and gradient.

Detailed description of the invention:
Embodiment: the following embodiment that utility model is described by particular specific embodiment, those skilled in the art can understand other advantages of the present utility model and effect easily by content disclosed in the present specification.
Indexable inverted cone degree helical end mills comprises: cutter hub 1, all teeth cutter blades 2, end tooth blade 3 and trip bolt 4, cutter hub 1 afterbody is coning angle D is 30 ° of cones 101, cone 101 diameter at butt end is 180mm, top diameter is 100mm, cone 101 big end surface opens screwed hole, there are six right hand helix cutting teeths on cone 101 surface, every bar cutting teeth is evenly equipped with seven all teeth cutter blades 2 and an end tooth blade 3, all teeth cutter blades 2 are SPHW120408 standard side blade, end tooth blade 3 is XPHW1504PPR standard side blade, every bar cutting teeth has eight M5 screwed holes, all teeth cutter blades 2 and end tooth blade 3 are fixed on the spiral cutting tooth of cutter hub by the trip bolt 4 be arranged in M5 screwed hole.
As shown in Figure 1, as the quenching degree that the material require high strength of cutter hub 1, high tenacity are become reconciled, and 42CrMo can meet above-mentioned requirements well, 42CrMo material is without obvious temper brittleness, and after modifier treatment, have higher fatigue limit and anti-this impact capacities many, low-temperature impact toughness is good, is the material of outstanding screw cutter.
42CrMo material diameter after modifier treatment that cutter hub 1 is selected can strengthen, groove also can deepen, what the insert groove installing all teeth cutter blades 2 also can become is difficult to processing, so must select lengthening handle slotting cutter, selected slotting cutter can be chosen small-diameter cutter and carry out processing blades groove.
As shown in Figure 4 and Figure 5, all teeth cutter blades 2 and end tooth blade 3 are fixed on the cutting edge by trip bolt 4, these two kinds of blades are the main cutting tools for cutting to work pieces process, the end tooth relief angle F of week teeth cutter blade 2 weeks angle of back of tooth E and end tooth blade 3 have employed the design of 11 °, find through overtesting, the relief angle of 11 ° can make that blade abrasion degree is minimum and the amount of feeding is maximum.
As depicted in figs. 1 and 2, end tooth blade 3 is parts that milling cutter contacts workpiece at first, the moment of its contact workpiece is also stressed maximum position in whole milling cutter tools system, in order to ensure the safe operation of end tooth blade 3, it highly must exceed the height of all teeth cutter blades 2 subsequently, and the height exceeded is 0.5mm.
As shown in Figure 4 and Figure 5, in order to all teeth cutter blades 2 and end tooth blade 3 can compress by fastened screw 4 securely, drill and ream screw hole Shi Yingshikong center inwardly eccentric 0.15 ~ 0.3mm.
Described embodiment in order to illustrative the utility model, but not for limiting the utility model.Any those skilled in the art all without prejudice under spirit of the present utility model and category, can modify to described embodiment, therefore rights protection scope of the present utility model, should listed by claim of the present utility model.
