BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of an embodiment of a punching machine supporting device according to the present invention, and FIG. 2 is an exploded perspective view thereof. In FIG. 1, 1 is a base fixed to a boring portion such as a curb 40 and 2 is a base 1. The spherical seat 3 installed on the upper surface, 3 is the spherical seat 2
It is an L-shaped lifting support stand that is mounted on top.

The base 1 is fixed by straddling a curb 40 to be punched and sandwiching the curb 40. For example, a fixing bolt 5 having a bowl-shaped contact portion 4 at its inner end is provided on both sides.
Alternatively, a plurality of them are provided, and the fixing bolt 5 is tightened, and the abutting portion 4 is fixed to the side surface of the curb 40 by applying strong pressure. At that time, the horizontalness of the upper surface of the base 1 need not be particularly considered.

The spherical seat 2 has a cylindrical shape having a flange 6, and an annular spherical seat 7 is formed on the upper surface thereof. Spherical seat 2
At the center of the bolt, there is a bolt 8 extending upward from the rear surface of the base 1.
Protrudes.

Reference numeral 9 denotes a hemispherical movable member, and a bolt insertion hole 1 into which a bolt 8 is loosely inserted with a sufficient gap in the center.
0 is pierced. On the upper surface of the hemispherical movable member 9, the horizontal portion 11 of the elevation support stand 3 is placed.

An elongated hole 12 extending in the longitudinal direction is formed on the bottom surface of the horizontal portion 11 (see FIG. 2), and the bolt 8 passes through the elongated hole 12 and projects further upward. A rack rail 21 that supports and guides the lifting operation of the punching machine 30 is installed on the vertical portion 13 of the lifting support stand 3.

The horizontal portion 11 is provided with a fixing means for fixing the end portion of the bolt 8 protruding from the elongated hole 12. The fixing means includes a fixing block 14 fixed on the horizontal portion 11, a bolt supporting member 15 in which the bolt 8 is inserted and is mounted on the upper surface of the fixing block 14 in a spherical pair state, and protrudes from the bolt supporting member 15. Nut 16 which is screwed to the tip of the bolt.

The fixed block 14 has a bolt insertion hole 17 which vertically penetrates through which the bolt 8 is loosely inserted, and an annular spherical seat 18 is provided at the upper end of the bolt insertion hole 17. It is formed. The bolt support member 15 abuts on the spherical seat 18 in a spherical pair state, and is fitted into the nut 1.
It is held down by 6.

The fixed block 14 has an extension portion 19 which abuts on the bottom surface of the horizontal portion 11 and extends therein, and a reaction force receiving bolt 20 is screwed into the extension portion 19 from above. The reaction force receiving bolt 20 extends through the bottom surface of the horizontal portion 11, and its tip reaches the flange 6 of the spherical seat 2.

The vertical portion 13 of the lift support stand 3 is erected at one end of the horizontal portion 11, a rack rail 21 extending in the length direction is installed on one side surface thereof, and a level 22 is arranged on the upper surface thereof. To be done. As mentioned above, this vertical section 1
The punching machine 30 is attached to the unit 3 so as to be able to move up and down. That is, the punching machine 30 includes a motor case 31 having a built-in motor and a drilling drill 32 extending downward from the motor case 31, and the vertical portion 3 penetrates the motor case 31 (see FIG. 1).

Although not shown, a pinion that meshes with the rack rail 21 is provided in the motor case 31, and a handle 33 for rotating the pinion is installed on the side surface of the motor case 31. Thus this handle 33
By operation, the motor case 31 and the drill 32
Can be moved up and down along the vertical portion 13.

In using the punching machine supporting device having the above-mentioned structure, the base 1 and the curbstone 4 are loosened with the fixing bolts 5 loosened.
0, etc., and after appropriately moving the base 1 so that the drill 32 is roughly aligned with the drilling position, the fixing bolt 5
The base 1 is firmly fixed by tightening. At that time, the upper surface of the base 1 does not necessarily have to be horizontal.

Next, the reaction force receiving bolt 20 and the nut 1
In the state where 6 is loosened, the elevating support stand 3 is moved in the horizontal direction for position adjustment (movable by the length of the long hole 12), while the level 22 is visually observed, the bolt 8 is used as an axis, Swing the vertical part 13 in any direction to set it vertically.

The rear surface of the horizontal portion 11 of the elevating support stand 3 is in close contact with the upper surface of the hemispherical movable member 9 and is supported thereby. The hemispherical movable member 9 is brought into a spherical pair state by the spherical seat 2. Since it is supported, the elevation support stand 3 can be freely moved in the three-dimensional direction. By performing this operation while visually observing the spirit level 22, the vertical portion 13 can be easily and surely made vertical, and thus the drill 32 can be vertically moved up and down for vertical drilling. .

When the vertical portion 13 is set vertically as described above, the nut 16 is tightened to fix the lifting support stand 3 in that state. At that time, even if the horizontal portion 11 is not in a state perpendicular to the bolt 8, the fixed block 1
4 and the bolt support member 15 are in a spherical pair state,
The bolt support member 15 moves freely, and the tightening force of the nut 16 surely acts on the elevating support stand 3.

Then, the motor is started and the drill 3
2 is rotated, and the handle 34 is rotated in this state to gradually lower the motor case 31. Thus, the piercing drill 32 bites into the curb 40 or the like and pierces vertically. The drilling diameter can be changed by replacing the drilling drill 32.
It can be any.

During the punching operation, a reaction force acts on the horizontal portion 11 and the end portion of the horizontal portion 11 tries to rotate counterclockwise in FIG. 3, but this movement is suppressed by the reaction force receiving bolt 20.

In the embodiment shown in FIG. 4, a spherical fixing member 24 which is supported in a spherical pair state is provided on the base 1, and the horizontal portion 11 of the elevation support stand 3 is fixed to the spherical fixing member 24. . The spherical fixing member 24 is fixed by being pressed from both sides. That is, a pair of pressing plates 25 and 26 are installed on the base 1 with the spherical fixing member 24 interposed therebetween, one pressing plate 25 is fixed on the base 1, and the other pressing plate 26 is pressed. It is attached to the tip of the bolt 27 and moves back and forth as the pressing bolt 27 moves back and forth. The pressing bolt 27 is screwed into the female screw hole of the support plate 28 installed on the base 1 and having the female screw hole.

In the case of this structure, the pressing bolt 27 is screwed back to separate the pressing plate 26 from the spherical fixing member 24 so that the spherical fixing member 24 can freely rotate, and the above-mentioned operation is carried out. As in the case of the configuration, the vertical portion 13 is set vertically. Then, the pressing bolt 27 is screwed to push the pressing plate 26 against the spherical fixing member 24. Thus, the spherical fixing member 24 is strongly sandwiched between the pressing plates 25 and 26 and is prevented from moving. Subsequent operations of the punching machine 30 and the like are the same as those in the above embodiment.

[0027]

As described above, according to the present invention, any person can easily and quickly set the vertical portion of the punching machine support stand vertically, and thus the drilling work in the vertical direction can be performed accurately and efficiently. The effect is to provide a perforator support device that allows it to be performed.
