Abstract
The utility model disclose it is a kind of include drilling rod with self-positioning microbit, the drilling rod has helical flute, and the front end of the drilling rod is integrally convexly equipped with three apex points, and three front ends of apex point are concordant, and three apex points are arranged in the front end of drilling rod in triangle tripartite confrontation.Three apex points are integrally convexly equipped with by the front end of drilling rod, coordinate three front ends of apex point concordant, and three apex points are arranged in the front end of drilling rod in triangle tripartite confrontation, it is quickly self-positioning to be realized in drilling, and can reduce in hole（Upper and lower hole position）Burr, improve drilling quality.
Description
Technical field
The utility model is related to field of drill technology, refers in particular to a kind of with self-positioning microbit.
Background technology
The requirement of light, thin, short, the small development trend of hyundai electronicses component and more and more higher reliability so that printing electricity
The drilling of road plate (PCB) sheet material plus requirement to hole position precision and hole wall quality are also constantly being lifted, and the micro- brills of existing PCB
Structure through development and differentiation after a while, in a very ripe stage.But, with the requirement of application market
Improve constantly and change, it is both stage that opportunity is challenged again that PCB drilling techniques enter one, and existing PCB drill bits
Apex point structure exist limitation, it is impossible to realize self-positioning so that the development of PCB drilling techniques enters bottleneck stage.
The content of the invention
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of band and makes by oneself the utility model
The microbit of position, it realizes self-positioning in drilling.
To achieve the above object, the utility model is using following technical scheme：
A kind of to include drilling rod with self-positioning microbit, the drilling rod has helical flute, the front end one of the drilling rod
Body is convexly equipped with three apex points, and three front ends of apex point are concordant, and three apex points are arranged in the front end of drilling rod in triangle tripartite confrontation.
Preferably, the apex point has both sides blade and a front cutting edge, and front cutting edge is connected between the blade of both sides.
Preferably, the inner close to each other and extension that turns forward of the front cutting edge of three apex points.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme understands：
Three apex points are integrally convexly equipped with by the front end of drilling rod, coordinate three front ends of apex point concordant, and three brills
Point is arranged in the front end of drilling rod in triangle tripartite confrontation, quickly self-positioning to be realized in drilling, and can reduce in hole（Up and down
Hole position）Burr, improve drilling quality.
More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings
The utility model is described in detail.
Brief description of the drawings
Fig. 1 is the sectional perspective schematic diagram of the preferred embodiment of the utility model.
Accompanying drawing identifier declaration：
10th, drilling rod 11, helical flute
20th, apex point 21, side tool sword
22nd, front cutting edge
Specific embodiment
Refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of the utility model, include drilling rod
10。
The drilling rod 10 has helical flute 11, and the front end of the drilling rod 10 is integrally convexly equipped with three apex points 20, this three brills
The front end of point 20 is concordant, and three apex points 20 are arranged in the front end of drilling rod 10 in triangle tripartite confrontation.
In the present embodiment, the apex point 20 has the front cutting edge 22 of both sides blade 21 and, and front cutting edge 22 is connected to both sides
Between blade 21, also, the front cutting edge 22 of three apex points 20 the inner close to each other and extension that turns forward.
Design focal point of the present utility model is：Three apex points are integrally convexly equipped with by the front end of drilling rod, coordinate three brills
The front end of point is concordant, and three apex points are arranged in the front end of drilling rod in triangle tripartite confrontation, so as to realized in drilling quickly from
Positioning, and can reduce in hole（Upper and lower hole position）Burr, improve drilling quality.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and can not by any way be construed to the limitation to the utility model protection domain.Based on explanation herein,
Those skilled in the art associates other specific embodiments of the present utility model by would not require any inventive effort,
These modes are fallen within protection domain of the present utility model.
