Abstract
The invention provides a novel drill bit device comprising a drill bit installation part, a drill bit and a pin. The drill bit comprises a taper shank at one end and a drilling tool at the other end. A groove is formed in the taper tail portion of the taper shank, the bottom face of the groove is an inclined face which inclines to the drilling tool, the drilling bit installation part is provided with a conical drilling hole matched with the taper shank, and the taper shank is inserted into the conical drilling hole; the pin is fixed to the upper portion of the groove, and the lower end of the pin makes contact with the inclined face of the groove and is fixed. The taper shank is arranged at one end of the drilling bit, so the contact face of the coaxial taper shank and the conical drilling hole is increased due to conical design, and torque is greatly improved. Besides, the groove with the inclined face as the bottom face is formed in the taper tail portion of the taper shank, the pin is fixed to the inclined face of the groove, and the reverse locking capacity of the taper shank is improved, so the taper shank is not easy to move, and stability is higher in use.

Technical field
The present invention relates to drill bit device field, particularly relate to a kind of new drill device.
Background technology
Existing drill bit device includes drill bit installation portion and drill bit, and drill bit includes staight shank and the brill inserting drill bit installation portion
Cutter, staight shank is cylindrical, and drill bit installation portion is provided with the cylindrical hole matched with cylindrical staight shank, is inserted in cylindrical hole by staight shank
After, insert with pin in the groove of staight shank and drill bit is fixed in drill bit installation portion.Owing to the cylindrical hole of drill bit installation portion is with straight
Handle is all cylindrical structural, and during installation, cylindrical hole inwall and staight shank outer surface are without coefficient of friction, basic torsionless.Torsion relies on pin
The active force of nail, owing to pin is single load bearing, can make cylindrical hole and staight shank produce gap, and lateral force is inclined to, and causes
Beat increase.
Summary of the invention
Based on this, it is necessary to provide that a kind of torsion is relatively big, reduce the new drill device that deflection is beated.
A kind of new drill device, including drill bit installation portion, drill bit and pin, described drill bit includes that the taper shank of one end is with another
The drill of one end, the terebrantia of described taper shank is provided with groove, and the bottom surface of described groove is an inclined-plane, and described inclined-plane is towards described
Drill direction tilts, and described drill bit installation portion is provided with the tapered bores matched with described taper shank, and described taper shank inserts described
In tapered bores；Described pin is fixed on described groove top, and the lower end of described pin is solid with the contact of incline plane of described groove
Fixed.
Wherein in an embodiment, the bus of described taper shank is 1 °～3 ° with the angle of the axle of described taper shank.
Wherein in an embodiment, the inclined-plane of described groove is 20 °～30 ° with the angle of the axle of described taper shank.
Wherein in an embodiment, the inclined-plane of described groove is provided with wearing layer.
Wherein in an embodiment, described wearing layer is ceramic layer.
Above-mentioned new drill device, owing to drill bit one end is set as taper shank, conical design makes axiality taper shank and taper
The contact surface of boring increases, and substantially increases torsion, and makes taper shank and tapered bores laminating degree high, it is possible to reaches slitless connection effect
Really, the deflection decreasing drill bit is beated；It addition, the terebrantia at taper shank is provided with the groove that bottom surface is inclined-plane, pin is fixed on
On the inclined-plane of groove, adding the reverse locked ability of taper shank, make taper shank not easily shifted, during use, stability is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the new drill device of the present invention；
Fig. 2 is the internal anatomy of the new drill device of the present invention；
Fig. 3 is the structural representation of the new drill device of another embodiment of the present invention；
Fig. 4 is the internal anatomy of the new drill device of another embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out detailed retouching
State, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based in the present invention
Embodiment, the every other enforcement that those of ordinary skill in the art are obtained on the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
Referring to Fig. 1 and Fig. 2, in an embodiment, a kind of new drill device, including drill bit installation portion 1, drill bit 2 and pin
Nail 3, drill bit 2 includes the taper shank 21 of one end and the drill 22 of the other end, and the terebrantia of taper shank 21 is provided with groove 211, groove 211
Bottom surface is an inclined-plane 211a, and inclined-plane 211a tilts towards drill 22 direction, and drill bit installation portion 1 is provided with and matches with taper shank 21
Tapered bores 11, taper shank 21 inserts in tapered bores 11；Pin 3 is fixed on groove 211 top, and the lower end of pin 3 is with recessed
The inclined-plane 211a contact of groove 211 is fixing.
Wherein, the bus of taper shank 21 is 1 °～3 ° with the angle of the axle of taper shank 21.The inclined-plane 211a of groove 211 and taper shank 21
The angle of axle be 20 °～30 °.
The installation process of above-mentioned new drill device is: the taper shank 21 of drill bit 2 inserts the tapered bores of drill bit installation portion 1
In 11, drill bit installation portion 1 is additionally provided with the through hole 5 making pin 3 pass, pin 3 through through hole 5 and is fixed on groove 211
On inclined-plane 211a, installation process can be completed.During pin 3 is fixed on inclined-plane 211a, owing to inclined-plane 211a is towards drill
22 directions tilt, and promote taper shank 21 to slide to the direction away from drill 22, make taper shank 21 more firm with the joint of drill bit installation portion 1
Gu, and be difficult to make taper shank 21 slide to drill 22 direction, improve the stability of product.
Above-mentioned new drill device, owing to drill bit one end is set as taper shank, conical design makes axiality taper shank and taper
The contact surface of boring increases, and substantially increases torsion, and makes taper shank and tapered bores laminating degree high, it is possible to reaches slitless connection effect
