Specific embodiment
The present invention will be further described With reference to embodiment, to better understand the technology of the present invention side
Case.
Embodiment 1: a kind of multi-functional expansion bit, referring to figures 1-3, the drill bit 2 including sleeve 1 and with sleeve one,
Alloy blade 7 is installed in bit face.4 slots 3 are provided in one end that circumference and drill bit close on, it is corresponding with 4 slots 3
4 rotating vanes 4 are installed in sleeve, the lateral surface of each rotating vane is arranged to shiny surface, and 4 rotating vanes are integrally formed
Annular shape, the upper end of each rotating vane 4 are inclined outwardly the inclined surface to be formed and be extended out upwards, each pivoting leaf from bottom to top respectively
The lower end of piece is inclined outwardly the inclined surface to be formed and be extended out downwards from top to bottom respectively, it is corresponding with 4 rotating vane upper surfaces
Drill bit circumference is provided with 4 inclined ramps 15, and the rotating vane can be free to slide along inclined ramp 15；And then 4 pivoting leafs
Piece is opened or is reduced.Annular shape is integrally formed in 4 rotating vanes, is pressed against on the inside of 4 rotating vanes, under rotating vane
End setting rotary screw 6, is provided with internal screw thread, the rotary screw and internal thread of sleeve Matching installation on sleeve lining.Institute
The end sleeve Xia Kou can be protruded by stating rotary screw lower end, can also be concordant with mouth under sleeve or under a bushing in mouth.Pivoting leaf
Piece can radially slide under rotary screw effect along bit inclination slideway, so that rotating vane is freely opened or is tightened, rotary screw
Middle part is set as hollow structure, and rotary screw is matched is provided with rotary screw radial positioning mechanism.Diameter in the present embodiment
It is positioning screw to positioning mechanism.Specifically, when rotating vane expands outward to certain angle under screw rod propulsion, with positioning
The inside fastening screw of screw can prevent screw rod radial direction precession.And then fixed boring aperture not further expansion, it is fixed to a value.By
It is expanded outwardly respectively under the propulsion of screw rod in rotating vane, it is easy to slot is popped up, to prevent rotating vane from throwing away outside slot, every
One metal insert 5 is installed from top to bottom respectively, metal insert can be from top to bottom at the outer edge of a rotating vane medial surface
The setting of full paving rotating vane inside edge, metal insert 5 can be prevented spin-ended when rotating vane is thrown away outward with clamping stagnation on the inside of slot
Rotating vane piece throws away slot, plays protective action.A set of shaping blades group, every set are installed respectively at each rotating vane outer ledge
Shaping blades group is made of 3 shaping blades arranged from top to bottom 8 respectively, and each shaping blades 8 are fixed by fixed screw 9
On rotating vane.Drill bit after installation forming blade can be used as forming cutter use.
Multi-functional expansion bit in the present embodiment is used as drill bit, and specific works situation is as follows: rotation rotary screw 6,
Screw rod struts rotating vane 4, and blade expands outwardly, and needs size when blade opens up into, screwed in place screw 10, by rotary screw
6 is fixed, prevents rotary screw from radially creeping into, and then boring aperture is fixed, at this time rotary screw can only position rotating, can bore
Hole.Thus the multi-functional expansion bit in the present embodiment, can bore aperture, macropore, can also can also be beaten after boring aperture with reaming
Reaming simultaneously again is opened, blind hole, taper hole can be done.Bore diameter is variable, and it is straight to can be drill bit through test drilling aperture variable range
1.5 times of diameter.This structure design can arbitrarily adjust rotating vane opening angle according to drilling size, and then adjust drilling
Diameter does not have to bit change, can bore a series of holes not of uniform size, be used primarily in machinery industry, carpenter's furniture, repairs profession etc.
It is very convenient using operating etc. the place for needing drilling, reaming.
Embodiment 2: a kind of multi-functional expansion bit ,-Fig. 5 referring to fig. 4, when multi-functional expansion bit works as the knot of drill bit used time
Structure is, referring to fig. 4-Fig. 6, and unlike the first embodiment: the lateral surface of each rotating vane in the present embodiment is provided with one
Alloy vane group is covered, the alloy vane 11 in every set alloy vane group tilts down setting, alloy vane group is integrally formed
Barb structure；The radial positioning mechanism is no longer positioning screw, but thin light-weight metal stick 13, and thin light-weight metal stick 13 is located at
Rotating vane lower end is arranged through sleeve wall, installs a rubber button 14 in thin light-weight metal stick end.Each rotating vane also
One globular tooth madding with alloy 12 is installed, 12 end of globular tooth madding with alloy can be used as blade use.The multi-functional expansion bit conduct of the present embodiment
Anchor head is used.
It is as follows as the job description of anchor head used time:
The first is as prestressing force anchor head: pressing Fig. 4 for drill bit, alloy blade, globular tooth madding with alloy, alloy vane, rubber button, spiral shell
Bar 6, metal insert 7, which install, can directly do prestressing force anchor head.Concrete operations are as follows: it is pre- that the component installed is inserted directly into wall
In molding hole, when reaching bottom hole, rotary screw, screw rod pushes alloy vane to open to prop up porthole inner wall, plays pre- anchoring
Effect.It is used primarily in tunnel, steel plate connects, in bridge connection.
Second as the directed drilling used time:
Installing drill bit, alloy blade, globular tooth madding with alloy, alloy vane, rubber button, screw rod, metal insert by Fig. 4 can be straight
It connects and does prestressing force anchor head, installing can do from brill positioning reaming anchoring drill bit.Concrete operations are as follows: directly cover assembled component
Wall is pierced on blower, after getting into suitable position, takes away blower, pierces into the hole among screw rod with a suitable reinforcing bar,
Small light-weight metal bastinade is broken, it is thrown at this time in set upper fan, blower drives screw rod, and screw rod is rotationally advancing in drill bit at this time,
Alloy vane is opened when screw rod contact alloy blade, drilling, positioning reaming, the work of directed drilling can be played at this time
With.
Finally, it should be noted that the rotating vane shape of the multi-functional expansion bit of the present invention is not only above-described embodiment public affairs
That opens is cylindric, can also need to be arranged to cuboid or hexagonal prisms, eight prisms according to drilling, rotating vane quantity is according to brill
Hole needs and aperture precision requested number is adjustable, is not only 4 of above-described embodiment, can also for 3,5,6 or
Person is multiple etc., all to belong to the scope of the present invention using technology approximate or only doing formal argument with the technology of the present invention design
Within.
