Abstract
The utility model relates to a kind of soldering hole teeth drill bits, including drill bit and drillstock；The drill bit and drillstock form an entirety by being brazed in succession together；The drill bit is equipped with multiple linked holes, and the linked hole at land side, processing, which is arranged, in the linked hole can be realized the passive heat dissipation of drill bit, simultaneously when using coolant liquid, coolant liquid can be made to enter drill bit by linked hole and reached by land, heat dissipation effect is greatly increased, improve drilling efficiency.
Description
[technical field]
The utility model relates to be brazed hole teeth drill bit, and in particular to a kind of soldering hole teeth drill bit.
[background technique]
With social development, mechanical processing industry is also more and more mature, and while slowly improving machining, machinery adds
Tool used in construction equipment is also being weeded out the old and bring forth the new, it is existing in drill bit soldered fitting heat dissipation effect it is poor, attaching stability is not
Good, service life is short, influences processing effect.
Therefore, it is necessary to a kind of soldering hole teeth drill bit, the drill bit is equipped with multiple linked holes, and the linked hole is arranged in tooth
Sword side, when processing, the linked hole can be realized the passive heat dissipation of drill bit, while when using coolant liquid, coolant liquid can be made logical
It crosses linked hole to enter drill bit and reach by land, greatly increases heat dissipation effect, improve drilling efficiency.
[utility model content]
The technical problem to be solved by the present invention is to, it is poor for the soldered fitting heat dissipation effect of the drill bit in existing,
The problems such as service life is short, influences processing effect proposes a kind of soldering hole teeth drill bit thus.
The technical scheme adopted by the utility model to solve the technical problem is as follows: including drill bit and drillstock；The drill bit with
Drillstock forms an entirety by soldering in succession；The drill bit is equipped with multiple linked holes, and the linked hole is arranged on land side,
The linked hole can be realized the passive heat dissipation of drill bit when processing, while when using coolant liquid, coolant liquid can be made to pass through connection
Through-hole enters drill bit and reaches by land, greatly increases heat dissipation effect, improves drilling efficiency.
In novel soldering hole teeth drill bit described in the utility model, the drillstock is the multi-diameter shaft shape constituted by two sections, one
Section is connect by soldering with drill bit, and a plurality of square protruding is axially uniformly distributed in the section, another section of taper equipped with 1-2 degree,
Clamping effect can be increased.
In novel soldering hole teeth drill bit described in the utility model, the drill bit has two spiral grooves, when drilling, clast
Object can be discharged from spiral groove automatically.
Implement in the teeth drill bit of soldering hole described in the utility model, it is multiple to have the advantages that the drill bit is equipped with
Linked hole, the linked hole at land side, processing, which is arranged, in the linked hole can be realized the passive heat dissipation of drill bit, while can
So that coolant liquid is entered drill bit by linked hole and reach by land, greatly increase heat dissipation effect, improves drilling efficiency, while drillstock
On have equipped with taper and square protruding, the stability of clamping can be increased, soldering hole teeth drill bit processing effect with higher
Rate and machining accuracy, long service life of the service life than traditional structure drill bit.
[Detailed description of the invention]
Fig. 1 is the perspective view of soldering hole teeth drill bit described in the utility model.
[specific embodiment]
As shown in Figure 1, in novel soldering hole teeth drill bit preferred embodiment described in the utility model, including drill bit (1) and
Drillstock (2)；The drill bit (1) and drillstock (2) are by being brazed one entirety of formation in succession；The drill bit (1) is equipped with multiple
Through-hole (3), on land (4) side, the drillstock (2) is equipped with a plurality of square protruding (5) for the linked hole setting；Described in when processing
Linked hole can be realized the passive heat dissipation of drill bit, while when using coolant liquid, coolant liquid can be made to enter brill by linked hole
Head simultaneously reaches by land, greatly increases heat dissipation effect, improves drilling efficiency.
In novel soldering hole teeth drill bit preferred embodiment described in the utility model, the drillstock (2) is to be constituted by two sections
Multi-diameter shaft shape, one section is connect by soldering with drill bit (1), and a plurality of square protruding, Ling Yiduan is axially uniformly distributed in the section
Taper equipped with 1-2 degree can increase clamping effect.
In novel soldering hole teeth drill bit preferred embodiment described in the utility model, the drill bit (1) has two
Spiral groove, when drilling, clast can be discharged from spiral groove automatically.
In novel soldering hole teeth drill bit preferred embodiment described in the utility model, the linked hole is arranged in land (4)
Side, when processing, the linked hole (3) can be realized the passive heat dissipation of drill bit, while when using coolant liquid, can make coolant liquid
(3) drill bit is entered by linked hole and reaches land (4) side, greatly increased heat dissipation effect, improve drilling efficiency, while on drillstock
Have and be equipped with taper and square protruding, the stability of clamping, soldering hole teeth drill bit processing efficiency with higher can be increased
With machining accuracy, long service life of the service life than traditional structure drill bit.
As described above, the only preferred embodiment of the utility model, when cannot be limited with this utility model implementation range,
All still belong to the utility model according to simple equivalent changes and modifications made by the utility model claim and novel description generally
In the range of patent covers.
