Description
Technical field
The utility model is related to wood materials drilling machining cutter, and in particular to hard alloy counterbore is bored.
Background technology
At present many positions are required for using screw solid wood furniture industry, and general Furniture manufacture factory is all with traditional carpenter
Come the screw installed, this mode causes that the horizontal tail portion of screw is exposed in plate face, and parts are attractive in appearance in the hole that drill bit is processed
Degree is affected, and exposed screw is larger for the fineness impact of plate face, and air can enter to exposed screw
Row corrosion.
Utility model content
The purpose of this utility model a kind of can process the screw hole with counterbore to provide so that the horizontal tail part of screw
Also can be installed to inside of furniture, and drilling depth can the hard alloy counterbore of quick regulation bore.
To realize the purpose of this utility model, the utility model is adopted the following technical scheme that：A kind of hard alloy counterbore is bored,
Include shank, cutter hub, cutting edge, drill core successively, wherein：The shank is provided with some open slots, and in the cutter hub use is provided with
In the centre bore for placing drill core, the centre bore through cutter hub and and in shank, the centre point of the centre bore, cutter hub circle
Heart point, shank centre point in the same horizontal line；Angle between the point of a knife and horizontal line of the bite is 70 degree -90
Degree, is capable of achieving the processing to taper hole.
It is preferred that the shank is provided with three open slots so that shank has elastic tension and relaxation power, realizes quick-clamping, uses
When drill core is loaded together with handle of a knife can clamp in machine tool chief axis or chuck handle of a knife and drill core, process very convenient, can be significantly
Improve operating efficiency.
It is preferred that, the centre bore is identical with the diameter of drill core so that connection is more firm.
It is preferred that, the shank is cylinder, and highly versatile is applicable to the drilling machine with chuck or joint.
It is preferred that, the cutting edge is made using hard alloy material, and the cutting edge is welded on cutter hub, and hard alloy is cut
Cut sword and drill on hard timber and timber layer sharper, in hgher efficiency, wearability is more preferable.
It is preferred that, the length cocoa of the drill core carries out free regulation, when using, it is only necessary to unclamp chuck or joint is i.e. adjustable
The length of section drill core.
The beneficial effects of the utility model：Bored using the hard alloy counterbore of above-mentioned structure, tied using drill body and drill core
Structure, using the Elastic Circular handle with opening, convenient mounting and clamping is applied to the drilling machine with chuck or joint (such as torch to handle of a knife
Bore, the rig such as bench drill), there is elasticity only to need from during clamping effect, processing use when handle of a knife is used together with drill core
Unclamp chuck or joint can adjust the length of drill core, you can realize quick regulation drilling depth, the hard alloy counterbore is bored
Screw hole can simultaneously be got out and accommodated the counterbore of cap nut and kept causing screw hole and accommodate the counterbore of cap nut same
On axis, cap nut is located at below plank plane after screw of screwing on.

Specific embodiment
Further illustrate below in conjunction with the accompanying drawings：
As shown in accompanying drawing 1-5：The utility model includes successively shank, cutter hub, cutting edge, drill core, wherein：The shank sets
There are some open slots, the centre bore for placing drill core is provided with the cutter hub, the centre bore is through cutter hub and and is located at
In shank, the centre point of the centre bore, cutter hub centre point, shank centre point in the same horizontal line；The bite
Point of a knife and horizontal line between angle be 70 degree of -90 degree, centre bore is identical with the diameter of drill core, shank be it is cylindrical,
Cutting edge is made using hard alloy material, and the cutting edge is welded on cutter hub.
Shank is provided with three open slots so that shank has elastic tension and relaxation power optimal, quick-clamping is realized, when use
Drill core is loaded together with handle of a knife and can clamp in machine tool chief axis or chuck handle of a knife and drill core, process very convenient, be greatly improved
Operating efficiency.
The length cocoa of drill core carries out free regulation, when using, it is only necessary to unclamp chuck or joint can adjust drill core
Length.
Angle between the point of a knife and horizontal line of bite is 90 degree, is realized higher to the accuracy rate of the processing of taper hole.
The purpose of this utility model, feature and advantage will be further described referring to the drawings in conjunction with the embodiments.By reality
Apply example to will be helpful to understand the utility model, but do not limit content of the present utility model.One of ordinary skill in the art can be from
All deformations that the utility model disclosure is directly derived or associated, are considered as protection model of the present utility model
Enclose.
