The present invention relates to drill bit designing technique fields, more particularly to a kind of three bone knob of multi-step taper bores, drill bit including drillstock and with drillstock integrated setting, the one end of the drillstock far from drill bit is fixedly connected with the installation end in polygon prism shape, junction between the installation end and drillstock is provided with dismounting slot, and the junction integral type of the drill bit and drillstock is provided with the baffle ring that a circle is excessively pierced for blocking drill bit;Compared with prior art, the beneficial effects of the invention are as follows:The configuration of the present invention is simple, reasonable design, a kind of three bone knob of multi-step taper brill, by the drill bit that a multi-step is arranged, it can be to the sheet metal drilling processing within 3mm, one straight drill is used instead of multiple drill bits, processes the hole of different-diameter as needed, and the disposable of macropore may be implemented and machine, it does not need more bit change and beats location hole, it is very convenient.

Description

A kind of three bone knob of multi-step taper brill
Technical field
The present invention relates to drill bit designing technique fields more particularly to a kind of three bone knob of multi-step taper to bore.
Background technology
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 operation principle be electromagnetic rotation or The rotor of electromagnetic reciprocating small capacity motor does magnetic field intercepts acting operating, and apparatus for work is driven by transmission mechanism, The power that drill bit is increased 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, holder, railing, billboard, air-conditioner outdoor unit, guide rail, satellite receiver electricity The installations 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, very big inconvenience is brought to production.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of three bone knob of multi-step taper brill, lead to The drill bit of one multi-step of setting is crossed, multiple drill bits can be replaced to make the sheet metal drilling processing within 3mm, a straight drill With processing the hole of different-diameter as needed, and the disposable of macropore may be implemented and machine, more bit change and need not beat Location hole, it is very convenient.
The present invention is achieved through the following technical solutions:
A kind of three bone knob of multi-step taper brill, including drillstock and the drill bit 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 dismounting slot, the drill bit and drillstock is provided with the baffle 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 far from the direction of drillstock, the drill bit farthest away from drillstock end set there are 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 baffle 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 invention are as follows:The configuration of the present invention is simple, reasonable design, it is more a kind of Three bone knob of rank taper bores, and by the way that the drill bit of a multi-step is arranged, can always be bored to the sheet metal drilling processing within 3mm Head replaces multiple drill bits to use, and processes the hole of different-diameter as needed, and the disposable of macropore may be implemented and machine, no It needs replacing drill bit and beats location hole, it is very convenient.
Description of the drawings

Fig. 2 is the drill bit and tip connection diagram of the present invention.
In figure:1, drillstock, 2, drill bit, 3, tip, 4, installation end, 5, dismounting slot, 6, baffle ring, 7, threaded hole.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
Referring to Fig. 1, Fig. 1 is the structural diagram of the present invention.
As a preferred embodiment of the invention, the present invention relates to a kind of three bone knob of multi-step taper brills, including drillstock 1 With the drill bit 2 with 1 integrated setting of drillstock, the one end of the drillstock 1 far from drill bit 2 is fixedly connected with the installation in polygon prism shape End 4, the junction between the installation end 4 and drillstock 1 are provided with dismounting slot 5, the junction of the drill bit 2 and drillstock 1 Integral type is provided with a circle for blocking the baffle 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, is bored on the drill bit 2 The graded diameter of knife gradually becomes smaller along the direction far from drillstock 1, the drill bit 2 farthest away from drillstock 1 end set there are one The tip 3 being detachably connected with drill bit 2, the position that the end of the drill bit 2 farthest away from 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.
Further, the baffle ring 6 is the bulge-structure that a circle height is 10mm, effectively prevent drill bit excessively to pierce, makes At the damage of thin plate to be drilled.
Further, the corner angle number of the installation end 4 is identical with the corner angle number of mounting groove, the ruler of the installation end 4 It is very little identical with the size of mounting groove.
Further, the tip 3 of 2 end of the drill bit is made of cubic boron nitride, has high hardness and Nai Gao Temperature characteristics.
In the use of the present invention, after drill bit is fixedly connected with drilling machine, tip and drill bit are screwed, you can start drilling and make Industry can replace multiple brills by the way that the drill bit of a multi-step is arranged to the sheet metal drilling processing within 3mm, a straight drill Head uses, and processes the hole of different-diameter as needed, and the disposable of macropore may be implemented and machine, need not more bit change With beat location hole, it is very convenient, it is more practical.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
