Description
Up to now, for fixing some bolt or timber, the problem of boring excavation cavity or flange hole only can lean on the instrument of more complicated to solve on concrete, plaster or similar wall, these instruments can not process shape and size kind cave widely, and are difficult for grasping.
The invention provides a kind ofly with the unusual method of simple tools boring excavation cavity of structure, and this method is very flexible, and uses easily.
The instrument of this invention comprises at least one movable blade, and blade is installed on the horizontal bearing pin on an elongated drill body top, can do the swing of angle.When drill body is inserted in the hole, when the drill body top is arrived at the bottom of the hole, apply axial thrust to it again, then above-mentioned blade promptly forms variable gradient, this is because the part profile of this blade can play action of cam, it and the profile of filling in a widget at the bottom of the hole match, can be when drill body have small axial displacement, and the blade part that makes blade becomes widthwise substantially from axis direction substantially.
The result of this arrangement is, blade is implemented to hollow out to the rightabout of axial thrust, and the reverse side at the bottom of the hole obtains a cave that comprises the larger volume of flange, and is like this, effective especially for the timber or the bolt of fixedly reaming or sealing.
At first embodiment, above-mentioned drip molding only is a ball at the bottom of putting the hole into, the method of this invention is with conventional drilling tool boring, ball is put in the hole, the blade of tool of invention is propped up ball, make the drill body fast rotational of instrument simultaneously with conventional method, and apply an axial compressive force, this ball is realized three kinds of functions at this moment, that is:
-its prevention instrument further deep-cuts along the axis in hole,
-it acts on the cam portion of blade, and blade is outwards arranged,
-by the rotation of himself all directions, it can adapt to the operating pressure of blade during around the rotation of drill body axis and around above-mentioned axis of pitch swing at blade.
In second embodiment, above-mentioned drip molding is an element that is installed on the instrument, and it comprises a cam portion and an extension.Cam portion remains in the cover of drill body top formation, and the cam contour of blade is through the drill body end, to support above-mentioned cam portion.The extension stretches out in outside the drill body top along the axis of elongated drill body, and an end that stretches out at it has the part in addition of a sphere, in order at the bottom of propping up the hole.
Method of the present invention is with a conventional bit boring, then with in the tool insert hole, props up the bottom in hole up to bulb, and makes the drill body rotation of instrument, applies axial thrust simultaneously.
In case flange forms, promptly available simple axial tension is extracted instrument out.In the process of extracting out, when originally radially outstanding blade is run into the forward position of flange, withdraw with regard to rotation.
Another feature of this invention is that the top of elongated drill body also must process dished sphere, to constitute the centering bowl of above-mentioned spheroid except that having one to install the opening of blade.
This centering bowl is the centering again for spheroid, this spheroid matches with blade, when beginning to carry out the operation of boring hole, earlier several balls is put in advance in the hole of boring with conventional bit, the blade of instrument is propped up, to bore the first in cave with a ball of packing at last.Take out after last ball, carry out the operation of second step,, by that analogy,, carry out the final step operation up to when only staying first ball at the bottom of the hole so that bore the second portion cave that links to each other with first.
Another feature of the present invention is, the axis of above-mentioned centering bowl and elongated drill body setover with respect to the axis of blade swing, and increase causes the leverage that blade is swung like this, especially near the lateral attitude of blade the time.
The present invention further advises, the blade openings on drill body top will with the center-biased of end face so that strengthen the end of elongated drill body, because of when instrument during around its axis rotation, the reaction force of blade and active force all put on the end of drill body.
To more clearly understand the features and advantages of the present invention from following narration:
In the accompanying drawings:

Figure 13 illustrates the boring hole method with several balls.
Figure 14 is the perspective diagram of Figure 11 and 12 shown type instrument movable ends.
Fig. 1 illustrates the phase I of process, and with conventional bit boring, a spheroid B then packs at the bottom of the hole earlier.In first embodiment, instrument of the present invention comprises elongated drill body C, its movable end have one can around axis * * the blade L of swing, blade also has a cam-type profile except cutting edge, be used for ball at the bottom of the support holes.Instrument applies a thrust around the longitudinal axis rotation of drill body C along above-mentioned axis.Bead blocks blade, stop it to the depths boring advance, when thrust increased, it also increased the gradient of blade on the other hand.
Fig. 3 shows that the blade of inclination will dig out a cave, and the cave is to form around the above-mentioned longitudinal axis, and its shape depends on the thrust that applies and the profile of blade cut sword.In order to increase the degree of depth in cave, can in same hole, carry out repeatedly continuous operation.
Bead can be made of a steel, and finishes the available flexible bar magnet in back in the boring hole and reclaims.
It is contemplated that the end of coming blade is installed to drill body with different solutions.
For example, one of them way is to open a groove in the drill body end, makes fork-shaped, blade is articulated in the fork, is rigidly fixed to the there, for example with welding and will pass two jointed shafts of pitching legs, collapse or with other any known way, two fork legs separately when preventing to use.A kind of like this layout can make tool firmer.
In addition, for the ease of with in the tool insert hole,, it is in along the outstanding position of drill body axis Yi Bian blade can blocked.
In above-mentioned example, can between blade and drill body, make the bearing-surface that cooperatively interacts to block blade.
Fig. 4 represents a kind of good especially blade example.Make two land portions L at the pivot pin end on blade two sides
1L
2With axle head L
3Encase, form a spheroid like this, just match with the corresponding spherical concave surface on instrument drill body top, and by means of at C '
2The crimping at place is clamped in there, as shown in Figure 6.
In Fig. 5, can see this concave surface C
1At its C
2Before the convolution, former is not a garden cylindrical openings at the edge, is a concave surface hemispherical in the bottom of garden tube opening.Fig. 6 shows, the spheroid of blade partly packed into after the spherical concave surface, with concave surface upper end convolution, so that embrace above-mentioned spheroid.Open a notch F along the opening surface of Cylinder C, reach the bottom of concave surface, blade is passed through from notch F.
In Fig. 4, can see the cutting edge L of blade
tTake turns the profile partial L with protruding
c
The longitudinal profile that has shown the instrument drill body in Fig. 7 therefrom can be seen an axial passage C
aWith concave surface C
1Communicate, drilling cuttings passes this passage, again from chip removal channel C radially
3Discharge.These access portal also can connect the flexible pipe (not shown), and centrifugal force produces low pressure in these pipes, with drilling cuttings sucking-off at the bottom of the hole.As a remodeling (as shown in Figure 7), also can a wind turbine T be installed on drill body C, be contained in C
2C
8Around, strengthen to inhale the drilling cuttings effect.
Fig. 8 illustrates second example above-mentioned, and spheroid B is replaced by an element that combines with instrument drill body C in this example.This element comprises a cam-shaped part E
c, be contained in the cover of drill body C top ends and an extension is stretched from cover, its end also is spherical E
bClearly, this spherical will prop up at the bottom of the hole, and cam portion E
cBe bearing on the protrusion profile of blade L, so that according to the gradient that puts on the axial thrust change blade on the instrument.Use this instrument, at the bottom of just not needing a spheroid stayed the hole, and recovery after each operation.
The present invention is not limited on the top of drill body only with a blade.For example, as Fig. 9 and shown in Figure 10, can hinged two blade L in the fork top ends of drill body C
1L
2, all match with same spheroid B.
The advantage of this example is: two blades are cutting in the opposite direction simultaneously, so they put on can cancelling out each other with joint efforts of transverse component on the drill body C.So the frictional force that is added on the above-mentioned drill body C just can reduce.
Self-evident, except that above introduction and the design of illustrated instrument, particularly with regard to blade and its shape, the people who is proficient in skill can design other different type, and does not surmount the scope of following claims.
In order to eliminate friction, thereby eliminate the wearing and tearing that drill body contact with hole wall, drill body at least will be partly with the collar that freely rotates or sleeve around.
In Figure 11 and 14, shown the movable top that has the blade L that swings around bearing pin A in the instrument drill body.The cutting edge L of blade
TBy cam contour L
CMatch with ball B body at the bottom of the hole and to extend to L
PThe point.When using above-mentioned processing method, instrument with direction shown in the arrow (seeing Figure 12) rotation, on drill body C applies axial thrust simultaneously around its axis, and then blade tilts gradually, when drill body has small moving axially, and the cutting edge L of blade
TBe converted to last widthwise substantially from original axis direction substantially, as shown in the figure.
So, at the cutting edge L that becomes with axial thrust under the effect of rightabout power
T, dug out a hole, garden around instrument axis of symmetry YY '.Please note thisly to hollow out effect and obtain in conjunction with applying axial thrust around axis YY ' rotation by instrument, with the use conventional bit take place when the initial action opposite, do not produce any impact.As can be seen from Figure 12, blade stretches out through notch F from the top end face, and in described decision design, this notch F setovers with respect to the center O of above-mentioned top end face.Consequently can make the end of drill body C have a side to be strengthened, when instrument when YY ' axis rotates, the reaction force of blade just is applied on the side that this intensity strengthens.So, eliminated because the danger that the blade that the distortion of tool surfaces brings breaks.
Figure 11 shows that the above-mentioned end face of drill body C constitutes a slightly larger in diameter in the spherical bowl C of sphere diameter.This shape of drill body C end has not only guaranteed the centering of ball, and partly provides a non-yielding prop at cell wall for blade.The design like this of cell wall part, when blade had smaller inclination with respect to YY ' axis, it surmounted the transverse plane that is tangential to the spherical bowl bottom.
Figure 11 shows that further bearing pin A is with respect to drill body C and bowl face C
2Axis of symmetry YY ' setover.Consequently: even when blade during near the lateral attitude, ball is applied to reaction force on it and the blade contact point and bearing pin A and is applied to reaction force on the blade and continues to form one and make blade to the power of laterally arranging.
Figure 13 shows that a cave of being made up of a series of continuous parts is obtained by following method: earlier with this instrument and B
1To B
4Ball cooperates the acquisition CH of first
1When operating for the second time, take out B
1Ball is with this instrument and B
2To B
4The ball cooperation just scrapes out second portion CH
2, below carry out like this.In this process, ball direct and that the blade cam contour matches is that even other ball is leaving the center in varying degrees, this does not have obstruction yet by the spherical bowl face centering of instrument.
Introduce a preferred example again: two " leg " BR that groove F separates above the drill body C
