Background technique
Electric drill is the drilling machine that power is done using electricity.It is the conventional products in electric tool, and have the call
Electric tool class product.Annual production and marketing quantity accounts for the 35% of Chinese electric tool.Electric drill working principle be electromagnetic rotation or
The rotor of electromagnetic reciprocating small capacity motor does magnetic field intercepts acting operating, drives apparatus for work by transmission mechanism,
The power for increasing drill bit with moving gear preferably pierces object to make drill bit scraping material surface.It is widely used in building
The reinforcing of beam, plate, column, wall etc., finishing, wall installation, bracket, railing, billboard, air-conditioner outdoor unit, guide rail, satellite receiver electricity
The installation such as ladder, steel-structure factory building.When needing to carry out more size hole drillings to sheet metal, ceaselessly more bit change is needed, very
Trouble, brings very big inconvenience to production.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of three bone knob of multi-step taper
It bores, by the way that the drill bit of a multi-step is arranged, multiple brills can be replaced to the sheet metal drilling processing within 3mm, a straight drill
Head uses, and processes the hole of different-diameter as needed, and disposably completing the process for macropore may be implemented, and does not need more bit change
With beat location hole, it is very convenient.
The utility model is achieved through the following technical solutions:
A kind of three bone knob of multi-step taper brill, the drill bit including drillstock and with drillstock integrated setting, the drillstock are separate
One end of drill bit is fixedly connected with the installation end in polygon prism shape, and the junction between the installation end and drillstock is provided with
The junction integral type of disassembly slot, the drill bit and drillstock is provided with the retaining ring that a circle is excessively pierced for blocking drill bit；
The outside of the drill bit is set as drill in gradient along the central axes in the middle part of drill bit, drill on the drill bit
Graded diameter gradually becomes smaller along the direction far from drillstock, and the end of the drill bit farthest away from drillstock is provided with one and drill bit can
The tip of dismantling connection, the position that the end of the drill bit farthest away from drillstock corresponds to tip are provided with threaded hole, the drill bit and
Tip is connected and fixed by helicitic texture.
Further, the screw thread in the threaded hole is the left-hand thread structure that junction can more fasten when drill bit bores dynamic.
Further, the retaining ring is the bulge-structure that circle height is 10mm, effectively prevent drill bit excessively to pierce, causes
The damage of thin plate to be drilled.
Further, the corner angle number of the installation end is identical with the corner angle number of mounting groove, the size of the installation end
It is identical with the size of mounting groove.
Further, the tip of the drill bit end is made of cubic boron nitride, has high hardness and high temperature resistant
Characteristic.
Compared with prior art, the beneficial effects of the utility model are: the utility model simple structure and reasonable design,
A kind of three bone knob of multi-step taper brill can drill to the sheet metal within 3mm by the way that the drill bit of a multi-step is arranged and add
Work, a straight drill are used instead of multiple drill bits, process the hole of different-diameter as needed, and the disposable of macropore may be implemented and add
Work is completed, and is not needed more bit change and is beaten location hole, very convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the drill bit and tip connection schematic diagram of the utility model.
In figure: 1, drillstock, 2, drill bit, 3, tip, 4, installation end, 5, disassembly slot, 6, retaining ring, 7, threaded hole.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram of the utility model.
As one preferred embodiment of the utility model, the utility model relates to a kind of three bone knob of multi-step taper brill,
Drill bit 2 including drillstock 1 and with 1 integrated setting of drillstock, the drillstock 1 are fixedly connected with far from one end of drill bit 2 in more ribs
Columnar installation end 4, the junction between the installation end 4 and drillstock 1 are provided with disassembly slot 5, the drill bit 2 and drillstock
1 junction integral type is provided with a circle for blocking the retaining ring 6 that drill bit 2 excessively pierces；
The outside of the drill bit 2 is set as drill in gradient along the central axes at 2 middle part of drill bit, bores on the drill bit 2
The graded diameter of knife gradually becomes smaller along the direction far from drillstock 1, and the end of drill bit 2 farthest away from the drillstock 1 is provided with one
The tip 3 being detachably connected with drill bit 2, the position that the end of drill bit 2 farthest away from the drillstock 1 corresponds to tip 3 are provided with screw thread
Hole 7, the drill bit 2 and tip 3 are connected and fixed by helicitic texture.
Further, the screw thread in the threaded hole 7 is the left-hand thread structure that junction can more fasten when drill bit bores dynamic.
