Description

[Detailed description of the invention] This invention relates to the improvement of a water-stop automatic drilling machine, and its first purpose is to make it possible to drill medium-diameter holes such as 50 mm with one machine, rather than the JfL diameter such as 13 cylinders. The purpose of this project is to provide an automatic drilling machine that can be used without water interruption.

The second object is to provide an automatic drilling machine that can automatically drill holes with a small diameter such as 12wn.

The third purpose is to provide an automatic drilling machine that can carry out drilling work at a site without electrical wiring using a batch IJ-car equipped with an automatic drilling machine that arrives at the site. This is what I am trying to do.

A fourth object is to provide an automatic drilling machine that is capable of reducing the feeding speed of the drilling tool.

Conventional continuous water drilling machines are capable of drilling holes with a diameter of 13 to 25 mm.
-There was a distinction between those for JL and those for middle holes such as 30 to 50 throat.

The reason for this is that it is difficult to attach a large drilling machine to a small water faucet, and even if it could be installed, the head of the water faucet would be damaged due to the weight and vibration of the drilling machine. However, there are drawbacks such as the possibility of breakage of drilling tools such as drills or cutters, and there is insufficient power to drill medium-diameter holes with small drilling machines, so it is recommended to use a drilling machine of a size commensurate with the diameter of the hole. As mentioned above, two types of drilling machines were used depending on the diameter of the hole.

Also, when attaching an automatic feeding device to automate a small drilling machine for drilling small holes such as 13 to 25 m in diameter, the drilling machine becomes larger and defects as described above occur. This is done manually; there is no automatic drilling machine.

Furthermore, there is no water-interruptible automatic drilling machine that uses the car's own battery and is configured to efficiently drill holes at sites where there is no electrical wiring.

The present proposal was devised in view of these points.The present proposal fixes the upper fixing member at a distance above the casing, fixes the upper surface of the upper fixing member (the screw body), and fixes the screw body and the upper An insertion hole passing through the fixing member is formed, and the end thereof is square, and an annular projection is provided below the square, and a rotation shaft with a thread carved on the outer circumferential surface is formed. The annular projection is brought into contact with the screw body, the rotation shaft is inserted into the insertion hole, and a nut loosely inserted into the rotation shaft is screwed into the screw body through the annular projection, while the rotation shaft is inserted into the insertion hole. A feed gear with a screw hole in the center is screwed into the feed gear through the screw hole, and a main shaft having a punching tool detachably fixed to the tip thereof is rotatably connected to the feed gear. A rotating body having a worm screw formed on the upper part of the worm foil is fitted onto the main shaft so as to be fixed in the rotational direction but freely movable in the vertical direction. By connecting a spur gear having a dimension longer than the axial length of the feed gear and parallel to the rotating shaft, meshing the spur gear with the feed gear, and configuring the worm wheel to be rotated by a power source, The shortcomings of the conventional method were overcome and the objectives stated at the beginning were achieved.

Next, an embodiment of the present continuous water perforation machine will be described based on the drawings.

1 in the drawings is a substantially bowl-shaped casing, and the bottom plate 2 of the casing 1 has a round hole 2a formed in the center thereof.

Also, a plurality of vertical holes 3 are bored near the outer edge.

Reference numeral 4 denotes a lid detachably fixed to the casing 1 in order to seal the open part of the casing 1, and a rotating body (to be described later) is positioned approximately in the center of the lid 4 on the same line as the round hole 2a. A through hole 5 through which a worm screw integrally formed passes through, and a shaft hole 6 for supporting the shaft of a bevel gear to be described later on the right side of the drawing are formed near the through hole 5.

Reference numeral 7 denotes an upper fixing member, and the upper fixing member 1 is detachably fixed to the upper ends of a plurality of columns 8 screwed and fixed to the cover plate 4.

Incidentally, instead of the upper fixing member 7 and the plurality of columns 8, a cylinder with a lid may be used, and the ceiling portion of the cylinder may be used as the upper fixing member.

Further, reference numeral 9 denotes a screw body fixed to the upper surface of the center portion of the upper fixing member I, and the screw body 9 and the center portion of the upper fixing member I are located on the same line as the through hole 5 formed in the lid body 4. As shown, an insertion hole 10 for a rotating shaft, which will be described later, is formed.

Reference numeral 11 denotes the aforementioned rotating shaft passing through the insertion hole 10. The head of the rotating shaft 11 is formed into a square shape so as to lock a bundle to be described later, and an annular protrusion 12 is provided slightly below the head.
is integrally formed, and a screw 13 is formed below the approximately central portion in the axial direction, and the annular protrusion 12 rests on the upper surface of the screw body 9, in other words, it is in contact with the screw body 9. It passes through the insertion hole 10 in this state.

Further, 14 is loosely inserted into the rotating shaft 11 and is connected to the screw body 9.
The nut 14 is screwed into the annular projection 12.
It is placed at the top of the

Therefore, when tightening the nut 14, the annular protrusion 12 comes into close contact with the upper surface of the screw body 9, and the rotating shaft 11, which is integrally formed with the annular protruding 12, becomes unable to rotate.When loosening the nut 14, the rotating shaft 11 It rotates.

Further, reference numeral 15 denotes a bearing provided on the lower surface of the upper fixing member T to ensure smooth rotation of the rotating shaft 11.

Further, 16 is a feed gear having a screw hole 16a in the center, and the screw 13 is screwed into the screw hole 16a of the feed gear 16.

Therefore, the feed gear 16 can be moved up and down by the action of the screw 13 when the rotating shaft 11 is fixed.

Further, 17a and 17b are a pair of split rings that are detachably fixed to the lower part of the feed gear 16.

Reference numeral 18 denotes a main shaft having a body portion 19, and a screw hole 20 is formed at the tip of the main shaft 18, into which a punching tool such as a cutter or a drill (not shown) can be freely screwed and fixed. An annular recess 21 is formed near the upper end.

However, the main shaft 18
With the lower part of the rotating shaft 11 protruding into the cavity 19,
Moreover, the tips of the pair of split rings 17a, 17b are connected to the feed gear 16 in a state that they protrude into the annular recess 21, and the lower portions thereof pass through the round hole 2a.

Therefore, when the feed gear 16 moves up and down, the main shaft 18 moves up and down in synchronization with this movement.

Reference numeral 22 denotes a bearing interposed between the feed gear 16 and the main shaft 18. Since the bearing 22 is provided, the main shaft 18 rotates smoothly as will become clear later.

Further, reference numeral 23 denotes a key groove provided in the outer circumferential surface of the main shaft 18 and facing in the axial direction.

Further, 24 is a rotating body having an inverted T-shaped longitudinal section and a through hole formed in the center, and a worm wheel 25 is formed by engraving worm teeth on the outer peripheral surface of the lower large diameter portion of the rotating body 24. A worm screw 26 is engraved on the outer periphery of the cylindrical portion that projects upward, and the rotary body 24 has a worm wheel 25 located inside the casing 1, and the worm screw 26 is inserted into the through hole. The main shaft 1B is fitted into the main shaft 1B so as to be positioned above the hole 5.
The rotating body 24 and the main shaft 18 are connected by a key 27 that is tightly fitted into a key groove 23 formed in the main shaft 18 .

Therefore, when the worm wheel 25 rotates, the main shaft 18 rotates synchronously.

Further, 28 is a bearing provided on the bottom plate 2 to ensure smooth rotation of the main shaft 18.

A worm wheel 29 is rotatably supported by a support 4a fixed to the lid 4 and meshed with the worm screw 26. A bevel gear 30 is integrally formed on the side surface of the worm wheel 29. It is formed.

Reference numeral 31 denotes a bevel gear, the end of which is rotatably supported in the shaft hole 6, and which meshes with the bevel gear 30.

Therefore, when the rotating body 24 rotates, the bevel gear 31 rotates.

Therefore, the upper end of the shaft 31a of the bevel gear 31 is connected to the shaft hole 3 which is on the same line as the shaft hole 6 formed in the upper fixing member I.
It is supported by 2.

The substantially central portion of the shaft 31a in the axial direction is long and has a large diameter, and a large number of grooves (spur gears) 33 are formed on the outer circumferential surface of the shaft 31a at the same pitch in the vertical direction. C meshes with the feed gear 16.

Further, the axial length of the spur gear 33 is the same as that of the feed gear 16.
The length in the axial direction is made longer than the length in the axial direction.

Therefore, when the bevel gear 31 rotates, the feed gear 16 rotates via the spur gear 33.

Further, a worm 34 meshes with the worm wheel 25 and is located inside the casing 1. The worm 34 is fixed to the end of the rotating shaft of the motor M.

Therefore, when the motor M rotates, the worm 34 rotates, and the rotation of the worm 34 causes the rotating body 24 to rotate via the worm wheel 25, and as a result, the feed gear 16 rotates via the spur gear 33 as described above. Moreover, the rotating body 24 causes the main shaft 18 to rotate once through the key 21.

Therefore, the rotation of the worm 34 is 6, 12 or 24.
Although it is advantageous to have a motor powered by a car battery, such as a volt motor, it may be rotated by a motor of other volts or by any other suitable means.

Further, 35 is in close contact with the outer peripheral surface of the main shaft 18,
This is an O-ring fixed to the bottom plate 2.

Next, we will explain how to use it and its effects.

First, the water distribution faucet X is fixed to a desired position of the water main via a saddle (both not shown).

The automatic perforating machine is fixed to the head of the fixed water distribution faucet X via the fixed flange Y using the vertical hole 3 formed in the bottom plate 2.

Therefore, by using the type of flange Y, in other words, by using a flange with a threaded portion that matches the threaded portion formed on the head of the water distribution faucet It can be installed.

Next, after tightening the nut 14 to fix the rotating shaft 11 as described above, the motor M is turned on and the motor M is rotated by the battery of the automobile.

Therefore, the motor can be rotated and drilling work can be performed even at sites where there is no electrical wiring.

When the motor M rotates as described above, the worm 34, the worm wheel 25 and the worm screw 2 are sequentially moved as described above.
6. Worm foil 29. The bevel gear 30 and the bevel gear 31 interlock, and the spur gear 3 is connected to the spur gear 3 through the shaft 31a of the bevel gear 31.
3 rotates.

Therefore, the feed gear 16 meshing with the spur gear 33
rotates.

On the other hand, a worm wheel 25 and a worm screw 26
Since the rotating body 24 formed with the key 2 rotates as described above, the key 2
The main shaft 18, which is connected to the rotating body 24 through the main shaft 1, rotates.

Accordingly, a drilling tool (not shown) screwed and fixed into a screw hole 20 at the tip of the main shaft 18 rotates.

As described above, since the feed gear 16 rotates to the left while the rotation shaft 11 is fixed, the feed gear 16 is moved downward by the action of the screw 13 formed on the rotation shaft 11, and as a result, it is connected by a pair of split rings 17a and 17b. main shaft 1
8 is guided by the key 27 and moves downward along the keyway 23.

That is, since the main shaft 18 moves downward while rotating, the water main is pierced by the drilling tool fixed to the tip of the main shaft 18 as described above.

In other words, automatic drilling is possible.

In addition, when drilling the hole, if the descending speed of the feed gear 16, in other words, the cutting speed of the punching tool is too fast and strain is applied to the motor M or the drilling tool, loosen the nut 14 and rotate the rotating shaft 11. The rotary shaft 11 is rotated via the handle in the same direction as the counterclockwise rotation of the feed gear 16 to reduce the descending speed of the feed gear 16, in other words, the cutting speed of the drilling tool, thereby reducing the unreasonable force. It can be resolved.

When drilling is completed, motor M stops rotating, and nut 1
4 is loosened, a handle (not shown) is attached to the square head portion of the rotary shaft 11, and the rotary shaft 11 is rotated counterclockwise to move the drilling tool upward via the feed gear 16 and the main shaft 18.

The upward movement of the punching tool causes the water to flow out to the outside, but the water is blocked by the O'J song 5 and there is no risk of leakage to the outside.

Incidentally, after the above-mentioned drilling tool has been moved up, branch piping is connected to the water distribution faucet using the usual method.

Next, manual drilling will be explained.

Loosen the nut 14 to enable the feed gear 16 and spur gear 33, which are screwed onto the rotating shaft 11 via the screw L16a, to rotate together, and then manually turn the handle attached to the square head of the rotating shaft 11. For example, when rotating clockwise, the rotation axis 11
Since the feed gear 16 screwed into the spur gear 33 meshes with the spur gear 33 and is subjected to resistance, the feed gear 16 does not rotate together and descends while rotating counterclockwise, and when the drilling tool reaches the drilling position,
The motor M is rotated and the drilling tool is rotated to perform drilling in the same manner as in the case of automatic drilling.

Of course, when the motor is driven, the rotation operation of the handle continues.

Further, the motor M is driven from the beginning to rotate the feed gear 16 via the spur gear 33 as described above, and the rotating shaft 11 is manually rotated via the handle to rotate the feed gear 16.
It is also possible to lower the hole and drill the hole.

After drilling, branch piping is connected to the water distribution faucet in the same manner as described above.

As is clear from the above explanation, the present waterless automatic drilling machine is
Since the drilling machine is constructed as described above and the entire drilling machine is miniaturized, it can be attached to a small water faucet to automatically and efficiently drill small holes such as 13 mm in diameter, and there is no problem in power transmission.
It was also possible to make holes with medium diameters such as 0fran.

Additionally, drilling work can be easily carried out even at sites where there is no electrical wiring.

Furthermore, the drilling speed can be slowed down as necessary, which has the remarkable effect of not putting strain on the motor or drilling tool.
