Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of hole making drill, including Tubular cover body and connecting shaft, wherein: also include that spitting drill, described spitting drill include that drill bit, described drill bit are provided with along hole making drill The locating notch offered of axle center, described tubular cover body includes cutting edge, is coated with diamond layer at described cutting edge.

By using technique scheme, spitting drill first contacts cut material part with tubular cover body, first gets hole, a location, Carrying out perforate cutting again, position is accurate, and cutting accuracy is high；Locating notch is offered at drill bit, thus the termination of spitting drill Having two most advanced and sophisticated location, spitting drill increases with the contact area of object to be processed simultaneously, it is not easy to skidding, locating effect is more Good；It is coated with one layer of diamond layer outside cutting edge, improves the intensity of cutting position.

This utility model is further arranged to: be coated with diamond layer outside described drill bit.

By using technique scheme, silicon carbide layer strengthens the intensity of the drill bit of spitting drill, locating notch energy simultaneously Enough increase the contact area of diamond layer, the contact area of silicon carbide layer during raising friction, thus abrasion thickness when completing boring Degree can reduce.

This utility model is further arranged to: at described connecting shaft, side opening is provided with screwed hole, arranges in described screwed hole Having dormant bolt, described spitting drill is provided with fixed gap, described dormant bolt is against stationary positioned at fixed gap and bores.

By using technique scheme, bolt is utilized to block spitting drill so that location turns the center being fixed on hole making drill, Simple in construction, and can easily install and take off, thus disassembling, assembling and replacing, dormant bolt can be carried out as required in different occasions Ensure that the smooth of surface at connecting shaft.

This utility model is further arranged to: described dormant bolt is hexagon socket head cap screw.

By using technique scheme, dormant bolt can easily be threaded into hole, and interior six by inner hexagon spanner It is difficult at angle skid, easily operates.

This utility model is further arranged to: be provided with sword groove at described cutting edge.

By using technique scheme, arranging of sword groove facilitates passing through of coolant, before cutting can easily be abundant Moistening cutting edge, on the one hand ensures that during cutting, temperature will not be too high, and the dust the most also avoiding cutting to produce splashes, it is ensured that cut Safety when cutting.

This utility model is further arranged to: be provided with double thread on described spitting drill.

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

This utility model is further arranged to: be arranged with back-moving spring outside described spitting drill, and described spring one end is connected on even In spindle.

By using technique scheme, during hole making drill perforate, the circular defective material scaled off is close with footpath in cylindrical cover body, Easily being stuck in cylindrical cover body, back-moving spring has thrust, it is thus possible to avoid defective material the deepest to the defective material entering tubular cover body Enter, facilitate defective material to take out.

This utility model is further arranged to: it is coniform that described connecting shaft connects one end of spitting drill.

By using technique scheme, the setting of cone-shaped structure, support triangular in shape to spitting drill, support effect is more Good, it is ensured that intensity when spitting drill uses, it is to avoid spitting drill wrecks.

In sum, this utility model has the advantages that

1, notched spitting drill, has stronger stationkeeping ability；

2, bolt is utilized to support spitting drill in axial restraint spitting drill, one end of connecting shaft cone, it is ensured that spitting drill Stable installation；

3, double thread cutting area is bigger, and efficiency is high.

Detailed description of the invention

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

Embodiment one:

A kind of hole making drill, referring to figs. 1 through Fig. 2, including tubular cover body 1, connecting shaft 2 and the spitting drill 3 with double thread, The drill bit 4 of spitting drill 3 offers locating notch 5, and locating notch 5 is perpendicular to the normal at drill bit 4 and by the axle of spitting drill 3 Line, tubular cover body 1 includes being coated with outside the cutting edge 6 of band sword groove 10, cutting edge 6 and drill bit 4 diamond layer, side at connecting shaft 2 Face offers screwed hole 7, and interior hexagonal dormant bolt 8 is conflicted through the fixed gap 9 on screwed hole 7, with spitting drill 3 and made spitting drill 3 fix, and be arranged with back-moving spring 11 and prevent cutting defective material from snapping in tubular cover body 1 outside spitting drill 3.

The principle of the present embodiment is: spitting drill 3 first contacts cut material part with tubular cover body 1, first gets hole, a location, Carrying out perforate cutting again, position is accurate, and cutting accuracy is high；Locating notch 5 is offered at drill bit 4, thus the end of spitting drill 3 Head has two most advanced and sophisticated location, and spitting drill 3 increases with the contact area of object to be processed simultaneously, it is not easy to skid, locating effect More preferably；It is coated with one layer of diamond layer outside cutting edge 6, improves the intensity of cutting position；Silicon carbide layer strengthens spitting drill 3 The intensity of drill bit 4, locating notch 5 can increase the contact area of diamond layer, connecing of silicon carbide layer when improving friction simultaneously Contacting surface is amassed, thus when completing boring, wear-thickness can reduce；Bolt is utilized to block spitting drill 3 so that location turn is fixed on out The center of hole device, simple in construction, and can easily install and take off, thus can carry out as required dismounting more in different occasions Changing, dormant bolt 8 ensure that the smooth of surface at connecting shaft 2；Dormant bolt 8 can easily be threaded into hole by inner hexagon spanner It is difficult at 7, and interior hexagonal skid, easily operates；Arranging of sword groove 10 facilitates passing through of coolant, can easily fill before cutting Sharing in the benefit wet cutting edge 6, on the one hand ensure that during cutting, temperature will not be too high, the dust the most also avoiding cutting to produce splashes, it is ensured that Safety during cutting；Double thread is when boring, and chip removal speed is faster, it is to avoid detritus accumulated plugging tapping；Hole making drill During perforate, the circular defective material scaled off is close with tubular cover body 1 internal diameter, is easily stuck in tubular cover body 1, and back-moving spring 11 is to entering The defective material entering tubular cover body 1 has thrust, it is thus possible to avoid defective material the most deep, facilitates defective material to take out.

Embodiment two:

With reference to Fig. 3, the present embodiment two and the difference of embodiment one are only that connecting shaft 2 one end towards spitting drill 3 is by former The plane come makes into coniform, and cone-shaped structure support triangular in shape to spitting drill 3, support effect is more preferable, it is ensured that spitting drill 3 Intensity during use, it is to avoid spitting drill 3 wrecks..

This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model The present embodiment can be made after reading this specification by field technique personnel 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.
