Embodiment
With reference to embodiment, the present invention will be further described, to be better understood from the technology of the present invention side
Case.
Embodiment 1：A kind of multi-functional expansion bit, referring to Fig. 1-Fig. 3, including sleeve 1 and the drill bit 2 with sleeve one,
Alloy blade 7 is installed in bit face.Be provided with 4 grooves in one end that its circumference and drill bit close on, it is corresponding with 4 grooves
4 rotating vanes 4 of installation, the lateral surface of each rotating vane are arranged to shiny surface in sleeve, and circle is integrally formed in 4 rotating vanes
Ring-type, the upper end of each rotating vane 4 is outward-dipping from bottom to top respectively to form the inclined plane extended out upwards, each rotating vane
Lower end it is outward-dipping from top to bottom respectively form the inclined plane that extends out downwards, it is corresponding with 4 rotating vane upper surfaces to bore
Head circumference is provided with 4 inclined ramps, and the rotating vane can be along inclined ramp slidably；And then 4 rotating vanes open
Or reduce.Annular shape is integrally formed in 4 rotating vanes, is pressed against on the inside of 4 rotating vanes, is set in rotating vane lower end
Rotary screw 6, internal thread, the rotary screw and internal thread of sleeve Matching installation are provided with sleeve lining.The rotation
Screw rod lower end can protrude sleeve Xia Kou ends, can also be concordant with mouth under sleeve or intraoral under a bushing.Rotating vane can be
Radially slided under rotary screw effect along bit inclination slideway, rotating vane is freely opened or is tightened up, set in the middle part of rotary screw
Hollow structure is set to, what is matched with rotary screw is provided with rotary screw radial positioning mechanism.Radial positioning in the present embodiment
Mechanism is positioning screw.Specifically, when rotating vane screw rod propulsion under expand outward to certain angle when, with positioning screw to
Interior fastening screw can prevent screw rod radial direction precession.And then fixed boring aperture not further expansion, fixed to a value.Due to rotation
Blade expands outwardly respectively under the propulsion of screw rod, it is easy to groove is ejected, to prevent rotating vane from throwing away outside groove, in each rotation
One metal insert 5 is installed from top to bottom respectively, metal insert can spread rotation entirely from top to bottom at the outer edge of blade medial surface
Rotating vane piece inside edge is set, and metal insert 5 can prevent rotating vane when rotating vane is outwards thrown away with clamping stagnation on the inside of groove
Groove is thrown away, plays protective action.A set of shaping blades group is installed respectively at each rotating vane outer ledge, per sleeve forming knife
Piece group is made up of 3 shaping blades arranged from top to bottom respectively, and each shaping blades are fixed on pivoting leaf by fixed screw 9
On piece.Drill bit after installation forming blade can be used as forming cutter to use.
Multi-functional expansion bit in the present embodiment is used as drill bit, and specific works situation is as follows：Rotary screw 8 is rotated,
Screw rod struts rotating vane 2, and blade expands outwardly, and needs size when blade opens up into, screwed in place screw 10, screw rod 8 is consolidated
It is fixed, prevent screw rod from radially creeping into, and then boring aperture is fixed, now screw rod can only position rotating, you can drilling.Thus this implementation
Multi-functional expansion bit in example, can bore aperture, macropore, can also reaming, can also be opened after aperture is bored again while reaming,
Blind hole, taper hole can be done.Bore diameter is variable, can be 1.5 times of bit diameter through test drilling aperture variable range.It is this
Structure design can arbitrarily adjust rotating vane opening angle, and then adjustment bore diameter, be bored without changing according to drilling size
Head, a series of holes not of uniform size can be bored, being used primarily in machinery industry, carpenter's furniture, repairs profession etc. needs to drill, expands
The place in hole, it is very convenient using operating.
Embodiment 2：A kind of multi-functional expansion bit, referring to Fig. 4-Fig. 5, when multi-functional expansion bit works as the knot of drill bit used time
Structure is, referring to Fig. 4-Fig. 6, as different from Example 1：The lateral surface of each rotating vane in the present embodiment is provided with one
Alloy vane group is covered, the alloy vane 11 often covered in alloy vane group tilts down setting, and alloy vane group is integrally formed
Barb structure；The radial positioning mechanism is no longer positioning screw, but thin light-weight metal rod 13, and thin light-weight metal rod 13 is located at
Rotating vane lower end is set through sleeve wall, and a rubber button 14 is installed in thin light-weight metal stick end.In each rotating vane also
One globular tooth madding with alloy is installed, globular tooth madding with alloy end can use as blade.The multi-functional expansion bit of the present embodiment is as anchor head
With.
It is as follows as the job description of anchor head used time：
The first is as prestressing force anchor head：By Fig. 4 by drill bit, alloy blade, globular tooth madding with alloy, alloy vane, rubber button, screw rod
6th, metal insert 7, which installs, can directly do prestressing force anchor head.Concrete operations are：It is preforming that the part installed is inserted directly into wall
Hole in, when reaching bottom hole, rotary screw, screw rod promotes alloy vane to open to prop up porthole inwall, plays pre- anchorage effect.
Tunnel is used primarily in, steel plate connects, in bridge connection.
Second of conduct 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 direct
Prestressing force anchor head is done, installing can do from brill positioning reaming anchoring drill bit.Concrete operations are：The part assembled is directly sleeved on
Wall is pierced on blower fan, after correct position is got into, takes away blower fan, the hole pierced into a suitable reinforcing bar among screw rod will
Small light-weight metal bastinade is broken, is now thrown into set fan, and blower fan drives screw rod, and screw rod is now rotationally advancing in drill bit, when
Alloy vane is opened, crept into during screw rod contact alloy blade, now can plays positioning reaming, the effect of directed drilling.
It is last 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 be needed to be arranged to cuboid or six prisms, eight prisms according to drilling, rotating vane quantity is according to brill
Hole need and aperture precision requested number can adjust, be not only 4 of above-described embodiment, can also be 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.
