Description
Technical field
The utility model is related to machining tool technical field, especially a kind of hard plank target drill.
Background technology
Drill bit is to be used to the drilling on solid material to go out through hole or blind hole, and can be to the cutter of existing hole reaming.It is hollow
Brill is the form cut using multi-blade ring-type, using the external diameter annulus of drill bit cutting hole, does not cut center section, from
And drilling efficiency is substantially increased, and combine magnetic support rig etc., it is possible to achieve the bore operation of scene at any time, relative to common
For fluted drill, efficiency is more increased, and is cut brisk.But for hard plank, it is hollow during processing because material is harder
The cylindricality hard wooden unit of drill bit internal formation is larger to wall friction in drill bit, be that drill bit is unstable, burr easily occurs excessive
Situation flash removed, it is necessary to which the subsequent handling that specially increases is made a return journey.
Utility model content
The technical problems to be solved in the utility model is：During in order to solve existing hollow boring bit to lignum vitae twist drill hole,
Because material is harder, during processing, the cylindricality hard wooden unit that hollow boring bit is internally formed is larger to wall friction in drill bit, be drill bit not
It is stable, easily there is the excessive situation of burr, it is necessary to which special increase subsequent handling is made a return journey the problem of flash removed, the utility model is carried
The cylindricality formed in a kind of hard plank target drill, the edge cutting of outer cutting blade device to hole, interior cutting blade device to hole is supplied
Hard wooden unit is cut, it is ensured that the stability of boring procedure, substantially reduces the formation of burr, thus reduce it is unnecessary after
Continuous processing.
The utility model solves the technical scheme that its technical problem used：A kind of hard plank target drill, including
Drillstock, brill body and drill bit, chisel edge are provided with the outer cutting blade for being used for cutting hard plank, and the brill body and drill bit have one
Interior cutting blade is provided with the cavity of body, the brill body, the interior bite cutlery has rotational trajectory, the interior cutting blade
Interior chip area is formed between rotational trajectory.
Preferably, the rotational trajectory bored provided with cutting blade in 4 groups in body.
Preferably, the brill body is provided with the chip removal mouth for being easy to bore chip discharge inside body.Boring the chip in body
When excessive, it can be discharged by chip removal mouth, while chip removal mouth can also overflow as an observation window when there is chip in chip removal mouth
Go out, drilling can be stopped, the chip in body is bored in cleaning.
Specifically, it is arranged with spline on the drillstock.
Specifically, the helical angle of the rotational trajectory is 30 ° -35 °.
The beneficial effects of the utility model are：The utility model provides a kind of hard plank target drill, outer bite
The cylindricality hard wooden unit formed in the edge cutting of sword device to hole, interior cutting blade device to hole is cut, it is ensured that boring procedure
Stability, substantially reduces the formation of burr, so as to reduce unnecessary following process；Bore body broken inside brill body provided with being easy to
Consider the chip removal mouth of discharge to be worth doing, when the chip in brill body is excessive, can be discharged by chip removal mouth, while chip removal mouth can also be used as one
Individual observation window, when there is chip spilling in chip removal mouth, can stop drilling, the chip in body, simple in construction, practicality are bored in cleaning
By force.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of hard plank target drill of the present utility model；
Fig. 2 is a kind of broken section structural representation of hard plank target drill of the present utility model
Fig. 3 is a kind of partial cross-sectional perspective view of hard plank target drill of the present utility model.
In figure：1. bodies are bored drillstock, 2., 3. drill bits, 4. outer cutting blades, cutting blade in 5., 6. rotational trajectories, rows in 7.
Consider groove, 8. chip removal mouths, 9. splines to be worth doing.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in Figure 1 to Figure 3, a kind of hard plank target drill 3, including drillstock 1, brill body 2 and drill bit 3, the front end of drill bit 3
Provided with the outer cutting blade 4 for cutting hard plank, boring body 2 and drill bit 3 has the cavity of one, bores and inscribe is provided with body 2
Sharpener sword 5, interior cutting blade 5, which has, be formed with interior chip area 7 between rotational trajectory 6, the rotational trajectory 6 of interior cutting blade 5.
In this specific embodiment, the rotational trajectory 5 provided with 4 groups of cutting blades 4 in body 2 is bored.
In a kind of embodiment, bore the top of body 2 and be provided with the chip removal mouth 7 for being easy to bore the inside chip discharge of body 2.Boring
When chip in body 2 is excessive, it can be discharged by chip removal mouth 7, while chip removal mouth 7 can also work as chip removal as an observation window
There is chip spilling in mouth 7, drilling can be stopped, the chip in body 2 is bored in cleaning.
Preferably, being arranged with spline 9 on drillstock 1.
Preferably, the helical angle of rotational trajectory 6 is 30 ° -35 °.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
