Abstract
The invention discloses a novel chamfering drill which is characterized by comprising a drill and a drill shank. The drill and the drill shank are integrally structurally connected with each other, the drill comprises a drill front end and a drill body, the drill front end and the drill body are integrally formed, and positioning grooves are formed in the drill shank and are close to the tail end of the drill shank. The novel chamfering drill has the advantage that the conical drill front end, a cutter and chip removal grooves are effectively combined with one another, accordingly, perforating and chamfering can be synchronously carried out, the drill changing time can be saved, the work efficiency can be improved, and the purpose of smoothly removing chips can be achieved.
Description
Technical field
The invention belongs to drill bit field, particularly relate 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.
Summary of the invention
The technical problem to be solved in the present invention is, cannot by boring and fall hole complete simultaneously, row cut obstructed.
For solving the problems of the technologies described above, the invention 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.
Beneficial effect of the present invention is as follows:
1, novel chmfer bit of the present invention, 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 invention 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 inventionly 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 invention.
If Fig. 2 is side view of the present invention.
Detailed description of the invention
Drawing reference numeral: 1, bite, 2, drill body, 3, row cuts groove, 4, drillstock, 5, positioning groove
For making goal of the invention of the present invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiments of the present invention are 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 invention; it is not the restriction to technical solution of the present invention; 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 patent of the present invention.
