Description

Diamond fluted drill

Technical field

This utility model relates to a kind of drilling tool, particularly to a kind of diamond fluted drill.

Background technology

At present, the Chinese patent of Publication No. CN204953985U discloses a kind of fluted drill, it includes the cutter hub of handle and twisted shape, the external diameter of described handle and the external diameter of cutter hub are equal, one end and the handle of described cutter hub are fixed, the other end of this cutter hub is provided with major cutting edge and rear knife face, the outer wall of this cutter hub is provided with chip pocket, the other end of described cutter hub is additionally provided with for guiding the chisel edge caused to chip pocket to repair thin groove chip, described chisel edge is repaiied and is provided with chisel edge on thin groove and repaiies thin groove rake face, described chisel edge repaiies thin groove rake face and major cutting edge and rear knife face is collectively forming the built-up edge for improving cutting edge sharpness.

But the tip that this fluted drill only relies on end positions, and locating effect is poor.

Utility model content

The purpose of this utility model is to provide a kind of well-located diamond fluted drill.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of diamond fluted drill, including drillstock and the cutter hub of twisted shape, wherein: described cutter hub includes chip ejection segment thereupon and drill bit, the tip of described drill bit is provided with the locating notch that the axle center along fluted drill is offered, and described drill bit is coated with a silicon carbide layer.

By using technique scheme, drill bit is provided with locating notch, only rely on a tip relative to traditional fluted drill to position, many terminations, a location, there are two most advanced and sophisticated location, the contact surface of the most advanced and sophisticated and processed material of fluted drill increases simultaneously, is more not easy to skid, good positioning effect；Silicon carbide layer strengthens the intensity of the drill bit of fluted drill, and locating notch can increase the contact area of silicon carbide layer, the contact area of silicon carbide layer during raising friction simultaneously, thus when completing boring, wear-thickness can reduce.

This utility model is further arranged to: described drillstock is provided with triangle joint head away from one end of cutter hub.

This utility model is further arranged to: the circumradius of described triangle joint head is identical with drillstock radius.

By using technique scheme, at direct drillstock, the convenient processing of the triangle joint head of cutting, also will not produce the sharpest edge simultaneously, use safety.

This utility model is further arranged to: be provided with quick link slot on described triangle joint head.

By using technique scheme, quick link slot can be connected together easily with the structure on equipment, easy to connect, it is simple to uses and changes.

This utility model is further arranged to: described drillstock is provided with some salient points away from the one side of cutter hub.

By using technique scheme, the end of drillstock is conflicted with equipment, if face is long for time of contact, is susceptible to contacting permeation, so that drillstock is bonded on equipment, the setting of salient point reduces contact area, it is to avoid fluted drill sticks.

This utility model is further arranged to: have double thread on described cutter hub.

By using technique scheme, double thread is when boring, and chip removal speed is faster, it is to avoid detritus accumulated plugging tapping.

This utility model is further arranged to: described chip ejection segment thereupon includes side cutting edge, and described side cutting edge is provided with some points of bits breach.

By using technique scheme, the setting of point bits breach makes the chip cut become narrow strip, also avoids side to produce too much chip simultaneously, can spread out in time, it is ensured that stablizing of cutting.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment one；

Fig. 2 is enlarged drawing at A in Fig. 1；

Fig. 3 is the structural representation of embodiment two.

In figure: 1, drillstock；2, chip ejection segment thereupon；3, drill bit；4, locating notch；5, triangle joint head；6, quick link slot；7, salient point；8, bits breach is divided.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Embodiment one:

A kind of diamond fluted drill, referring to figs. 1 through Fig. 2, including drillstock 1 and double thread cutter hub, cutter hub is divided into chip ejection segment thereupon 2 and drill bit 3, the locating notch 4 of drill bit 3, the locating notch 4 tangent line vertically and at drill bit 3 tip, and by the axis of spitting drill, being coated with a silicon carbide layer at drill bit 3, triangle joint head 5 directly cuts on drillstock 1 and goes out, being provided with quick link slot 6 at triangle joint head 5, drillstock 1 is provided with three salient points 7 away from one end of cutter hub.

The principle of the present embodiment is: drill bit 3 is provided with locating notch 4, only rely on a tip relative to traditional fluted drill to position, many terminations, a location, there are two most advanced and sophisticated location, the contact surface of the most advanced and sophisticated and processed material of fluted drill increases simultaneously, more it is not easy to skid, good positioning effect；Silicon carbide layer strengthens the intensity of the drill bit 3 of fluted drill, and locating notch 4 can increase the contact area of silicon carbide layer, the contact area of silicon carbide layer during raising friction simultaneously, thus when completing boring, wear-thickness can reduce；The directly convenient processing of the triangle joint head 5 of cutting at drillstock 1, also will not produce the sharpest edge simultaneously, use safety；Quickly link slot 6 can be connected together easily with the structure on equipment, easy to connect, it is simple to use and change；The end of drillstock 1 is conflicted with equipment, if face is long for time of contact, is susceptible to contacting permeation, so that drillstock 1 is bonded on equipment, the setting of salient point 7 reduces contact area, it is to avoid fluted drill sticks；Double thread is when boring, and chip removal speed is faster, it is to avoid detritus accumulated plugging tapping.

Embodiment two:

With reference to Fig. 3, with the difference of embodiment one, the present embodiment two is only that at the side cutting edge of chip ejection segment thereupon 2 being provided with some points considers breach 8 to be worth doing, can make the chip cut become narrow strip, also avoid side to produce too much chip simultaneously, can spread out in time, it is ensured that stablizing of cutting.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
