Abstract

The utility model discloses a kind of New type drilling drill bit, connected and composed by apex point, drill body body and drillstock three part, its innovative point is: described drill body body is polymorphic structure, and one end of described drill body body is connected with drillstock, and described drill body body and drillstock are structure as a whole; The other end of described drill body body is connected with apex point, and the external screw thread of described drill body body front end is connected with apex point end internal thread; The structure of described apex point is triangle body, and the structure of described drillstock is slender cylinder.Helicitic texture and bite effectively combine by drill bit of the present utility model, achieve the object that drill bit is easy to change, and the cutting blade row bevel in two faces is long-pending large, and the row of being easy to cuts, thus avoids the generation of bit freezing event.

Description

A kind of New type drilling drill bit
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of New type drilling drill bit.
Background technology
Cutter on brill, drilling machine, rig, 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.
At present, the drill bit of mine, oil drilling uses three dental drill heads mostly, its operating principle uses horizontal gear wheel to roll work plane, the technological deficiency that this prior art exists is: drill bit life cycle is short, when drilling harder geological structure, easy bit freezing, probing progress is slow.And the apex point position of the drill bit of prior art and drill body body part are integrative-structures, thus once apex point is along bad, so whole drill bit all cannot utilize again, wastes excessive.
Utility model content
The technical problems to be solved in the utility model is single use and the easy bit freezing of probing of drill bit, and progress is slow.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of New type drilling drill bit, connected and composed by apex point, drill body body and drillstock three part, it is characterized in that: described drill body body is polymorphic structure, one end of described drill body body is connected with drillstock, and described drill body body and drillstock are structure as a whole; The other end of described drill body body is connected with apex point, and the external screw thread of described drill body body front end is connected with apex point end internal thread; The structure of described apex point is triangle body, and the structure of described drillstock is slender cylinder.
Further, the thickness of described triangle body apex point is 1 ~ 2cm, and height is 5 ~ 7cm, and the number of degrees of drift angle are 35 ~ 45 °.
Further, two clinohedrals of described triangle body apex point are uniform-distribution with continuously arranged bite, the structure of described bite is conical, and the drift angle number of degrees of described conical bite are 15 ~ 30 °.
Further, described drillstock end offers external screw thread.
Further, the maximum gauge of described drillstock, drill body body and apex point is than being 1:3:3.
The beneficial effects of the utility model are as follows:
1, helicitic texture and bite effectively combine by drill bit of the present utility model, achieve the object that drill bit is easy to change, and the cutting blade row bevel in two faces is long-pending large, and the row of being easy to cuts, thus avoids the generation of bit freezing event;
2, apex point end of the present utility model is provided with internal thread, and the outer end of drill body body is provided with the external screw thread matched with apex point the inner, can realize the repeatedly utilization of drill bit like this when apex point occurs damaged by changing apex point;
3, apex point portion of the present utility model is provided with two sides bite, and the row's of making bevel is long-pending large, thus is conducive to the timely eliminating of chip in drilling process, avoids the generation of bit freezing, increases the application life of prospecting bit drill bit;
4, drillstock end of the present utility model offers external screw thread device, the drill jig of drill bit and electric drill can be installed with screw device, increases the steadiness installed, and reduces the obscission under bit operation state.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
If Fig. 2 is lateral view of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, bite, 2, apex point, 3, drill body body, 4, drillstock, 5, external screw thread device
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.
The structure of drill bit of the present utility model as shown in Figure 1, a kind of New type drilling drill bit, connected and composed by apex point 2, drill body body 3 and drillstock 4 three part, it is characterized in that: drill body body 3 is polymorphic structure, one end of drill body body 3 is connected with drillstock 4, and drill body body 3 and drillstock 4 are structure as a whole; The other end of drill body body 3 is connected with apex point 2, the external screw thread of drill body body 3 front end is connected with apex point 2 end internal thread, apex point 2 end is provided with internal thread, the outer end of drill body body 3 is provided with the external screw thread matched with apex point 2 the inner, can realize the repeatedly utilization of drill bit like this when breakage appears in apex point 2 by changing apex point 2; The structure of apex point 2 is triangle body, and the structure of drillstock 4 is slender cylinder.Helicitic texture and bite 1 are effectively combined, achieve the object that drill bit is easy to change, and the bite 1 in two faces to arrange bevel long-pending large, the row of being easy to cuts, thus avoids the generation of bit freezing event.Drillstock 4 end offers external screw thread, the maximum gauge of drillstock 4, drill body body 3 and apex point 2 is than being 1:3:3, drillstock 4 end offers external screw thread device 5, the drill jig of drill bit and electric drill can be installed with screw device, increase the steadiness installed, reduce the obscission under bit operation state.
The lateral view of drill bit of the present utility model as shown in Figure 2, two clinohedrals of triangle body apex point 2 is uniform-distribution with continuously arranged bite 1, and the structure of bite 1 is conical, and the drift angle number of degrees of conical bite 1 are 15 ~ 30 °.
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.
