Description
Technical field
The utility model relates to a kind of brill milling composite cutter, belongs to cutting element technical field.
Background technology
Along with the development of equipment manufacture, more and more refinement is divided the work in the manufacture of parts, in order to enhance productivity, present knockdown special plane gets more and more, by the restriction of processing stations, special plane requires that a station can realize multiple function, thus require more and more higher to the composite performance of cutter, but the cutting principle of drilling and milling is completely different, both are combined with each other in Tool Industry be technological difficulties.
Summary of the invention
A kind of brill milling compound tool, comprise handle of a knife, be located at the cored screw shape cutting portion of handle of a knife one end and be located at the apex point of cutting portion outer end, it is characterized in that, described cutting portion comprises the symmetrical milling cutter Zhou Ren of at least two circumferences, described apex point has the symmetrical apex point Zhou Ren of at least two circumferences simultaneously, and centre also has a chisel edge.
Preferably, described cutting portion comprise respectively with each milling cutter Zhou Ren milling cutter groove one to one, described apex point comprise respectively with each apex point Zhou Ren apex point groove one to one.
Preferably, described cutting portion comprises the symmetrical milling cutter Zhou Ren of four circumferences, and described apex point has the symmetrical apex point Zhou Ren of two circumferences simultaneously.
Preferably, two apex point grooves of described apex point are simultaneously respectively as two milling cutter grooves of cutting portion.
Preferably, described apex point diameter is less than cutting portion diameter.
Preferably, the helical angle of described cutting portion is 30 °.
Preferably, form the ladder of transition between described apex point and cutting portion, the ladder angle of transition is 90 °.
The beneficial effect that the utility model reaches:
1. brill milling compound tool of the present utility model, ingeniously incorporates drill bit function and milling cutter function, arrange at least two apex point Zhou Ren and milling cutter week sword be equipped with chisel edge, can be used for the processing of auto parts and components and mould.The processing of drilling and milling can be realized without tool changing, special plane uses and can greatly enhance productivity.
2.the milling cutter groove coordinating each milling cutter Zhou Ren is set, and coordinates the apex point groove of each apex point Zhou Ren, the respective intensity of apex point and cutting portion and chip removal performance can be ensured.
3.cutting portion arranges four milling cutter Zhou Ren, and apex point arranges two apex point Zhou Ren simultaneously, can make better to coordinate between drilling with milling, improve stock-removing efficiency simultaneously.
4.two apex point grooves of apex point, simultaneously as two milling cutter grooves of cutting portion, not only can reduce difficulty of processing, increase tool strength, and do not affect chip removal quality.
5.the helical angle of design cutting portion is 30 °, obtains best chip removal performance and cutter rigidity.
6.the ladder of transition is formed between apex point and cutting portion, and the ladder angle of transition is 90 °, make energy well transition between cutter of the present utility model its apex point Zhou Ren and milling cutter Zhou Ren, and enable this cutter once complete the processing of stepped hole, there is chamfering between stepped hole two sections of diameters simultaneously, more stable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1-2, a kind of brill milling compound tool, comprises handle of a knife 2, is located at the cored screw shape cutting portion 3 of handle of a knife 2 one end and is located at the apex point 1 of cutting portion 3 outer end.Cutting portion 3 comprises the symmetrical milling cutter week sword 32 of four circumferences, and apex point 1 has the symmetrical apex point week sword 12 of two circumferences simultaneously, and centre also has a chisel edge.
Concrete, cutting portion 3 comprise respectively with each milling cutter week sword 32 milling cutter groove 34 one to one, simultaneously apex point 1 comprise respectively with each apex point week sword 12 apex point groove 14 one to one.Namely have four milling cutter grooves 34 and two apex point grooves 14, wherein two apex point grooves 14 of apex point 1 are simultaneously respectively as two milling cutter grooves 34 of cutting portion 3.Setting like this, each milling cutter week sword 32 there is respective milling cutter groove 34, each apex point week sword 12 also have respective apex point groove 14, therefore can ensure apex point 1 and the respective intensity of cutting portion 3 and chip removal performance.Two apex point grooves 14 of apex point 1 are simultaneously as two milling cutter grooves 34 of cutting portion 3 in addition, not only can reduce difficulty of processing, increase tool strength, and do not affect chip removal quality.Especially cutting portion 3 arranges all swords 32 of four milling cutters, and apex point 1 arranges all swords 12 of two apex points simultaneously, can make better to coordinate between drilling with milling, improve stock-removing efficiency simultaneously.
Apex point 1 diameter D1 is less than cutting portion 3 diameter D3, the ladder 4 of transition is formed between apex point 1 and cutting portion 3, and ladder 4 angle of transition is 90 °, ladder 4 be arranged so that its apex point of cutter of the present utility model week sword 12 and milling cutter week sword 32 between can well transition, and enable this cutter once complete the processing of stepped hole, there is chamfering between stepped hole two sections of diameters simultaneously, more stable.In addition, the helical angle ω of cutting portion 3 is 30 °.Obtain best chip removal performance and cutter rigidity.
The present embodiment bores milling compound tool by the function and service of drilling and milling on a cutter, thus can realize the processing of drilling and milling without tool changing, special plane uses and can greatly enhance productivity.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
