Abstract

A kind of novel chmfer bit, its innovative point is: be made up of drill body and drillstock two parts, the connected mode of described drill body and drillstock is structure as a whole, described drill body is made up of drill body head and drill body body two parts, described drill body head and drill body intrinsic single are shaped, and described drillstock is provided with positioning groove near end.Novel chmfer bit of the present utility model, cuts groove by cone drill body head, bite and row and effectively combines, and reaches boring, chamfering and synchronously carries out, and has saved the time of bit change, has improve operating efficiency, and row cuts unobstructed object simultaneously.

Description

A kind of novel chmfer bit
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of novel chmfer bit.
Background technology
Cutter on brill, drilling machine, drilling machine, can cause hole on workpiece or rock.Xu Chi " Goldbach's Conjecture's oil head ": " in 1956, China's bored material was somewhat nervous, and drill bit is not enough." course of work dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit.
In prior art, boring and chamfering are completed to crisp hard nonmetallic materials, be generally by boring after again chamfering operation complete, different instruments and contraposition must be changed through secondary when using the method for chamfering of first holing again, the contraposition of Chang Yin center is inaccurate and cause bias, and general rice is said, must first just can carry out to correct accurately and to test through skilled skilled worker, this method not only wastes test article, more affects work efficiency because of the increase of operation.
Utility model content
The technical problems to be solved in the utility model is, cannot by boring and fall hole complete simultaneously, row cut obstructed.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of novel chmfer bit, it is characterized in that: described novel chmfer bit, be made up of drill body and drillstock two parts, the connected mode of described drill body and drillstock is structure as a whole, described drill body is made up of drill body head and drill body body two parts, and described drill body head and drill body intrinsic single are shaped, and described drillstock is provided with positioning groove near end.
Further, the structure of described drill body head is cone, the cone of described cone is high is 8 ~ 10cm, described cone drill body head surface offers three rows and cuts groove, described three rows cut groove and are evenly distributed in conical surface, cone drill body head is divided into 3 parts uniformly, and described each row cuts groove and is provided with 2 bites, and the angle of described bite and horizontal axis is 15 ~ 35 °.
Further, the structure of described drill body body is cylinder, and the diameter of described drill body body is consistent with the maximum gauge of cone drill body head.
Further, the structure of described drillstock is slender cylinder, and length is 12 ~ 15cm, and the diameter of described drillstock and the diameter of cylinder body are than being 1:3, the surface of described drillstock offers down two positioning grooves in the localities by subterminal, and the structure of described positioning groove is semicircle spheroid.
The beneficial effects of the utility model are as follows:
1, novel chmfer bit of the present utility model, cuts groove by cone drill body head, bite and row and effectively combines, and reaches boring, chamfering and synchronously carries out, and has saved the time of bit change, has improve operating efficiency, and row cuts unobstructed object simultaneously;
2, drillstock place of the present utility model is provided with upper and lower two positioning grooves, facilitates the drill jig of drill bit and electric drill to be fixed, and avoids coming off under bit operation state;
3, be of the present utility modelly provided with three rows and cut groove, row cuts groove and is provided with bite, and under duty, broken the cutting produced after being cut by bite is discharged timely, avoids broken blocking of cutting, affects the running of drill bit.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
If Fig. 2 is side view of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, bite, 2, drill body, 3, row cuts groove, 4, drillstock, 5, positioning groove
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of novel chmfer bit, it is characterized in that: be made up of drill body 2 and drillstock 4 two parts, the connected mode of drill body 2 and drillstock 4 is structure as a whole, drill body 2 is made up of drill body head and drill body body two parts, drill body head and drill body intrinsic single are shaped, and drillstock 4 is provided with positioning groove 5 near end.
The structure of drill body body is cylinder, and the diameter of drill body body is consistent with the maximum gauge of cone drill body head.The structure of drillstock 4 is slender cylinder, and length is 12 ~ 15cm, and the diameter of drillstock 4 and the diameter of cylinder body are than being 1:3, and the surface of drillstock 4 offers down two positioning grooves 5 in the localities by subterminal, and the structure of positioning groove 5 is semicircle spheroid.The structure of positioning groove facilitates the drill jig of drill bit and electric drill to be fixed, and avoids coming off under bit operation state.
As shown in Figure 2, the structure of drill body head is cone, the cone of cone is high is 8 ~ 10cm, cone drill body 2 front-end surface offers three rows and cuts groove 3, three rows cut groove 3 and are evenly distributed in conical surface, cone drill body head is divided into 3 parts uniformly, each row cuts groove 3 and is provided with 2 bites 1, bite 1 is 15 ~ 35 ° with the angle of horizontal axis, under duty, broken the cutting of bite 1 being cut rear generation is discharged timely, avoids broken blocking of cutting, affects the running of drill bit.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
