Description
Technical field
The utility model relates to numerically-controlled machine tool precision machinery manufacture field, specially a kind of Novel drilling cutter.
Background technique
NC cutting tool is the tool that machining is used in machine-building, also known as cutting element.The cutting element of broad sense was both
It further include grinding tool including cutter；" NC cutting tool " further includes knife bar and knife handle etc., such as Fig. 1 institute in addition to the blade of cutting simultaneously
Show, existing away drill cuttings generally can only disposable drilling processing from the top down, the drilling of staircase structural model cannot be processed, and
And the easy frizzled feather thorn in aperture edge after drilling.
Utility model content
The problem of for background technique, the utility model provide a kind of Novel drilling cutter.
To achieve the above object, the utility model provides the following technical solutions: a kind of Novel drilling cutter, including knife handle,
The knife handle bottom end is provided with single order spiral cutting blade and second order spiral cutting blade, the single order spiral cutting blade bottom
For bit cutting blade, single order filleted corner is provided between the single order spiral cutting blade and the second order spiral cutting blade and is cut
Sharpener sword is provided with second order filleted corner cutting blade between the second order spiral cutting blade and the knife handle.
As the utility model a preferred technical solution, the bit cutting blade is pyramidal structure.
As the utility model a preferred technical solution, the bit cutting blade is horizontal structure, and the drill bit is cut
Bull nose cutting blade is provided between sharpener sword and the single order spiral cutting blade.
As the utility model a preferred technical solution, the single order filleted corner cutting blade and the second order spiral
Rake angle cutting blade is provided between cutting blade.
Compared with prior art, the utility model has the beneficial effects that away drill cuttings by being designed to by the utility model
Stepped construction can complete opening up for straight hole and counter sink, the counter sink for needing multiple processing actions originally is disposably added
Work is completed, entire processing action efficient quick, and oilhole/oil circuit interface inner wall smooth after in addition processing is without flange, one-pass molding
Processing can also guarantee safety factor, effectively prevent causing safety accident because of oil leak, terminal with compact integral structure is practical, have compared with
For vast market prospect, it is convenient for promoting.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1:
Referring to Fig. 2, the utility model provides a kind of Novel drilling cutter, including knife handle 1,1 bottom end of the knife handle setting
There are single order spiral cutting blade 2 and second order spiral cutting blade 3,2 bottom of single order spiral cutting blade is drill edge
Sword 4 is provided with single order filleted corner cutting blade 5 between the single order spiral cutting blade 2 and the second order spiral cutting blade 3,
Second order filleted corner cutting blade 6 is provided between the second order spiral cutting blade 3 and the knife handle 1.
In the specific implementation process, the bit cutting blade 4 is pyramidal structure.
As shown in figure 3, part 9 can be moved on to a cutter through this kind of away drill cuttings when processing to part
Surface directly process counter sink 11 can also independent drill straight hole 10, and aperture burr (such as 9 hole of straight hole can be removed by the way
Mouthful), it is efficient and convenient, the repeatedly movement such as tool changing processing is eliminated, (such as counter sink 11) is processed at one time and can guarantee hole
Concentricity, can be made in entire hole using single order filleted corner cutting blade 5 with second order filleted corner cutting blade 6, aperture it is hairless
Thorn and flange.
Embodiment 2:
Referring to Fig. 4, the utility model provides a kind of Novel drilling cutter, including knife handle 1,1 bottom end of the knife handle setting
There are single order spiral cutting blade 2 and second order spiral cutting blade 3,2 bottom of single order spiral cutting blade is drill edge
Sword 4 is provided with single order filleted corner cutting blade 5 between the single order spiral cutting blade 2 and the second order spiral cutting blade 3,
Second order filleted corner cutting blade 6 is provided between the second order spiral cutting blade 3 and the knife handle 1.
In the specific implementation process, the bit cutting blade 4 is horizontal structure, the drill bit cutting blade 4 and described one
It is provided with bull nose cutting blade 7 between rank spiral cutting blade 2, the further single order filleted corner cutting blade 5 and institute
It states and is provided with rake angle cutting blade 8 between second order spiral cutting blade 3.
Based on above-mentioned, the utility model has advantages in that the utility model by the way that away drill cuttings are designed to ladder
Formula structure can complete opening up for straight hole and counter sink, the counter sink for needing multiple processing actions originally is disposably processed
At entire processing action efficient quick, oilhole/oil circuit interface inner wall smooth after in addition processing is without flange, simultaneous manufacturing
It can also guarantee safety factor, effectively prevent causing safety accident because of oil leak, terminal with compact integral structure is practical, has more wide
Wealthy market prospects, convenient for promoting.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
