Be included into drill bit one kind.
Existing drill bit knife edge part diameter is identical, cylindrical, influences the drilling and withdrawing process of drill bit, the effect of drilling
Rate is lower, and existing drill bit is integral structure mostly, when carrying out bit change-over, needs to carry out more entire cutter
It changes, too very complicated.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of numerically controlled lathe drill bit
Existing drill bit knife edge part diameter same affect drilling efficiency and the most integral structure of drill bit are inconvenient to the problem of replacing.
To achieve the above object, the utility model provides the following technical solutions: a kind of numerically controlled lathe drill bit, including cutter head
And knife handle, the cutter head is fixedly mounted on the side of knife handle by attachment base, and the shape of the cutter head is taper, the cutter head
On be fixedly installed with several cutting edges, fixation offers chip space between the two neighboring cutting edge, and the attachment base is remote
Side from cutter head is fixed with connecting column, several circle external screw threads is fixed on the connecting column, the knife handle is close to cutter head
Side be fixed with groove, the inner sidewall of the groove is equipped with several circle internal screw threads, several circle external screw threads and interior spiral shell
Line is threadedly coupled.
As a kind of optimal technical scheme of the utility model, the two sides of several cutting edges are fitted with water cooling
Layer.
As a kind of optimal technical scheme of the utility model, the top of several water-cooled layers is fitted with wear-resisting
Layer.
As a kind of optimal technical scheme of the utility model, the diameter of the connecting column and the diameter of groove are identical.
As a kind of optimal technical scheme of the utility model, the material of the cutter head is made of high-alloy steel materials.
Compared with prior art, the utility model has the beneficial effects that a kind of numerically controlled lathe drill bit of the utility model, leads to
It crosses and cutter head is shaped to taper, be conducive to drill, the effective drilling efficiency for improving drill bit, by being set on attachment base
There is connecting column, connect by connecting column with knife handle, when carrying out cutter changing, it is only necessary to cutter head is replaced, it is simpler
Fast.
Detailed description of the invention
Fig. 1 is the positive structure schematic of the utility model；
Fig. 2 is the attachment structure schematic diagram of the utility model；
Fig. 3 is the water cooling schematic diagram of a layer structure of the utility model.
In figure: 1, cutter head；2, knife handle；3, attachment base；4, cutting edge；5, chip space；6, water-cooled layer；7, wearing layer；8, even
Connect column；9, external screw thread；10, groove.
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.
Fig. 1-3 is please referred to, the utility model provides a kind of numerically controlled lathe drill bit, including cutter head 1 and knife handle 2, cutter head 1
The side of knife handle 2 is fixedly mounted on by attachment base 3, and the shape of cutter head 1 is taper, is fixedly installed with several on cutter head 1
Cutting edge 4, fixation offers chip space 5 between two neighboring cutting edge 4, and attachment base 3 is fixed with company far from the side of cutter head 1
Column 8 is connect, several circle external screw threads 9 are fixed on connecting column 8, knife handle 2 is fixed with groove 10, groove close to the side of cutter head 1
10 inner sidewall is equipped with several circle internal screw threads, and several circle external screw threads 9 are threadedly coupled with internal screw thread.
Preferably, the two sides of several cutting edges 4 are fitted with water-cooled layer 6, and water-cooled layer 6 helps cutting edge 4 at work,
Rapid cooling prevents when work temperature is excessively high cutting edge 4 is caused to damage.
Preferably, the top of several water-cooled layers 6 is fitted with wearing layer 7, and wearing layer 7 prevents from leading when being worked
Water-cooled layer 6 is caused to destroy.
Preferably, the diameter of connecting column 8 is identical as the diameter of groove 10, and diameter is identical to make connecting column 8 and groove 10
Cooperate even closer.
Preferably, the material of cutter head 1 is made of high-alloy steel materials, and the hardness strength of high-alloy steel materials is higher, is prolonged
