Description
Technical field
The utility model relates to the technical field of drill bit, particularly relates to a kind of combined drill.
Background technology
Drill bit, as the Common Use Tools on the instrument such as drilling machine, drilling machine, is often used in workpiece, rock, plank, ground being caused required various holes.
Existing drill bit arranges the tip of creeping into usually on knife bar, by applying rotary power on knife bar, thus drive tip above to rotate, by the cutting edge on tip, cutting operation is carried out on workpiece, rock, plank, ground, utilize the feeding on knife bar simultaneously, drive tip to travel forward, thus realize whole drilling process.
And conventional drill bit only has a tip, a kind of hole of diameter can only be got out, and when needs different-diameter hole, then need the drill bit of different-diameter, and when creeping into, also need manually to dismantle, thus cause more complicated operation and the cost of Geng Gao.
For this reason, designer of the present utility model is because above-mentioned defect, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of combined drill, to overcome above-mentioned defect.
Utility model content
The purpose of this utility model is to provide a kind of combined drill, and its structure is simple, has saved the raw material of a large amount of production drill bit, can be applicable to creeping into of different pore size, saves operation, reduces costs.
For solving the problem, the utility model discloses a kind of combined drill, at least comprising knife bar, the first cutter head, the second cutter head and the 3rd cutter head, it is characterized in that:
Described first cutter head is integrally formed at the lower end of knife bar, its periphery is provided with spiral helicine first cutting edge, described second cutter head is integrally formed at the lower end of the first cutter head, its periphery is provided with spiral helicine second cutting edge, described 3rd cutter head is integrally formed at the lower end of the second cutter head, its periphery is provided with spiral helicine 3rd cutting edge, and the diameter of described first cutter head, the second cutter head and the 3rd cutter head successively decreases successively.
Wherein: also comprise the 4th cutter head that diameter is less than the 3rd cutter head, described four blade head is integrally formed at the lower end of the 3rd cutter head, its periphery is provided with spiral helicine 4th cutting edge.
Wherein: described first cutting edge, the second cutting edge, the 3rd cutting edge, the 4th cutting edge be many articles and helical arrangement in periphery.
Wherein: the end periphery of described knife bar is provided with spline connection, described spline connection is provided with the spline of many equi-spaced apart arrangements, and the lower end of described spline connection is also provided with multiple locating slot.
Wherein: described locating slot is half slot.
Wherein: the outer rim of described knife bar is also provided with at least one chip removal portion.
Known by said structure, combined drill of the present utility model has following effect:
1, structure is simple, can be applicable to creeping into of different pore size, save the raw material of a large amount of production drill bit, raised the efficiency;
2, handling are convenient, and it is firm to connect, and chip removal is quick.
Detailed content of the present utility model obtains by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
Fig. 1 shows the structural representation of combined drill of the present utility model.
Fig. 2 shows the structural representation of another embodiment of the utility model.
Reference numeral:
10, knife bar; 11, the first cutter head; 12, the second cutter head; 13, the 3rd cutter head; 14, the 4th cutter head; 101, spline connection; 102, locating slot; 103, chip removal portion.
Detailed description of the invention
See Fig. 1 and 2, show combined drill of the present utility model.
In the embodiment shown in fig. 1, described combined drill at least comprises knife bar 10, first cutter head 11, second cutter head 12 and the 3rd cutter head 13, wherein said first cutter head 11 is integrally formed at the lower end of knife bar 10, its periphery is provided with spiral helicine first cutting edge, described second cutter head 12 is integrally formed at the lower end of the first cutter head 11, its periphery is provided with spiral helicine second cutting edge, described 3rd cutter head 13 is integrally formed at the lower end of the second cutter head 12, its periphery is provided with spiral helicine 3rd cutting edge, and described first cutter head 11, the diameter of the second cutter head 12 and the 3rd cutter head 13 successively decreases successively, thus, piercing and the operations such as reaming of different pore size can be realized, and replace without the need to multiple drill bit, save operation, improve efficiency.
Wherein, also can comprise the 4th cutter head 14 that diameter is less than the 3rd cutter head 13, described 4th cutter head 14 is integrally formed at the top of the 3rd cutter head 13, its periphery is provided with spiral helicine 4th cutting edge, the cutter head successively decreased gradually by the 4th cutter head and even more diameters is arranged, can better raise the efficiency, reduce costs.
Wherein, described first cutting edge, the second cutting edge, the 3rd cutting edge, the 4th cutting edge be many articles and helical arrangement in periphery, thus form the spiral fried dough twist cutter head of twisted shape, chip removal is more efficient and convenient.
The embodiment basic structure of Fig. 2 is identical with above-mentioned, for realizing connection and the location of knife bar, the end periphery of described knife bar 10 is provided with spline connection 101, and described spline connection 101 is provided with the spline of many equi-spaced apart arrangement, thus connect firm, power transmission is more firm, the upper end of described spline connection 101 is also provided with multiple locating slot 102, to provide axial positioning function, wherein, described locating slot 102 can be half slot, inserting for place kick.
