Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drill aid for assisting a drilling operation with a drill.

[0002]

2. Description of the Related Art Conventionally, the beam on the ceiling of a Shinkansen vehicle has
A plurality of reinforcing members are attached for the reinforcement.
Since this reinforcement is attached to the beam using bolts and nuts, first apply the reinforcement to the place to be reinforced,
An operation of drilling a bolt hole penetrating the reinforcing member and the beam has been performed.

FIG. 7 is a schematic view showing a state in which an operation of drilling a bolt hole using a drill is performed. As shown in FIG. 7, the operation of drilling a bolt hole in the reinforcing member must be performed in an unnatural posture in which the arm is lifted by holding the drill 100 in the hand, and the reinforcing plate is strong due to its nature. Since it is a metal plate, when drilling a bolt hole, it was a heavy work that had to keep pushing the drill 100 strongly toward the ceiling.

Therefore, in order to improve the posture when performing this work and reduce the burden on the operator, a drill assisting tool as shown in FIG. 8 has been developed. FIG. 8A is an external view of the drill assisting tool, and FIG. 8B is a schematic view showing a state of an operation of drilling a bolt hole by the drill assisting tool.

The drill aid configured as described above is assembled as follows.

A cylindrical column 46 is attached through a through hole 44 to the flat plate 20 to which the attachment aid 22 is welded so as to form the attachment margin 26. The fastener 24 is welded to the flat plate 20. The female screw portion 42 is screwed into the male screw portion 48 to
To the cylindrical column.

The drill holder 3 is attached to the operation rod 2. For this reason, since a bolt hole through which a bolt can be inserted is formed in the attachment 30 and the attachment allowance 26, the attachment 30 and the attachment allowance 26 are brought into contact, and the bolt is passed through the bolt hole and fastened. Attach the suction tube 50 to the bolt holder. for that reason,
Since a bolt hole through which a bolt can be inserted is formed in the suction tool mounting piece 34 and the mounting piece 506, the suction tool mounting piece 34 and the mounting piece 506 are brought into contact, and the bolt is passed through the bolt hole and fastened. .

The collection bag 54 is attached to one end of the duct 52, and the other end of the duct 52 is attached to the discharge section 504. Thus, the drill aid 1 is completed. Then, the drill a is attached to the drill aid 1 in the following procedure.

First, the ring holder 32 is widened. Then, the drill a main body can be inserted freely, so that the drill a is inserted into the ring holder 32 from the distal end side where the drill b is attached. Then, since the tip of the drill b comes into contact with the suction tube 50, the drill b is passed through the drill insertion hole 509, and the drill a body is further inserted into the ring holder 32.

The tip of the drill b is the drill peripheral portion 500.
When a predetermined length of the drill a protrudes from the ceiling surface, the drill a is held, and the ring holder 32 is tightened to fix the drill a (see FIG. 1). Finally, the drill a attached to the drill auxiliary tool 1 is a drill driven by compressed air,
Since a discharge port a1 for discharging air is provided, a connection is made from the discharge port to the air feed pipe 508 with a tube a2 for compressed air.

The drill aid 1 configured as described above
Is used as follows. Fig. 4 shows the drill aid 1
FIG. 5 is a schematic view showing a state in which a metal reinforcing plate x for reinforcing a beam constituting a ceiling portion of a Shinkansen vehicle is drilled with bolt holes for inserting the reinforcing plate x and the beam, and FIG. It is a schematic diagram which shows a mode that the position of the operation stick 2 is adjusted in order to carry the front-end | tip of the drill b to the drilling position of a hole. In FIG. 5, the suction tube 50 is omitted.

First, since there are a plurality of latches 40 in which the latching recesses 41 are formed in various widths, the thickness of the latch (the reinforcing plate b in this embodiment) to which the drilling aid 1 is to be hooked is included. An object provided with the retaining recess 41 wider than that is selected and attached to the cylindrical column 46. Next, as shown in FIG. 4, a latch 40 is hooked on the reinforcing plate x attached to the ceiling. Then, the operation rod 2 is suspended so as to swing around the retaining recess 41.

The user has the grip B of the operating rod 2 and the grip of the drill a, strokes a switch for driving the drill a, and pulls the grip B downward. Then, the drill b at the tip of the drill a is pressed against the reinforcing plate xb by the lever action. As shown in FIG. 5, since the operation rod 2 is slidable with respect to the support 4, in the longitudinal direction of the operation rod 2,
The drill a is moved by sliding the operation rod 2 so that the tip of the drill is drilled at the bolt hole.

In the direction perpendicular to the longitudinal direction of the operation rod 2, the support member 4 is assembled by screwing with the female screw portion 42 and the male screw portion 48. Move the drill a. Also, the length of the drill b changes according to the size of the diameter of the bolt hole to be drilled.
When the drill b is not perpendicular to the reinforcing plate x when drilling, the support 4 is screwed and assembled with the female screw portion 42 and the male screw portion 48. Adjust the height by rotating the part.

Since the drill of this embodiment is of the type driven by compressed air as described above, when the air discharged from the drill is fed from the air feed pipe 508 into the suction tube 50. The suction force acts on the drill peripheral portion 500. The suction force acting on the drill peripheral portion 500 will be briefly described below.

First, FIG. 6 is a schematic diagram showing the operation of the suction cylinder 5. The arrows in the figure indicate the direction in which the air flows. As shown in FIG. 6, the compressed air discharged from the discharge hole a1 of the drill a is sent to the air feed pipe 508. Then, the air discharged from the air feed pipe 508 into the suction tube 5 passes through the discharge portion 504 and is discharged vigorously in the direction of the duct 52 (not shown).

Then, a suction force from the drill peripheral portion 500 to the discharge portion 504 acts in the suction tube 5 due to the Venturi effect. Therefore, chips generated during the work of drilling the bolt holes are stored in the collection bag 54 from the suction tube 50 through the duct 52.

The suction force increases as the flow rate of the compressed air discharged from the drill a1 increases. As described above, the use of the drill aid 1 of the present embodiment has the following effects.

When the drill aid 1 of this embodiment is used, by pulling the operating end B of the operating rod 2 downward, the drill b at the tip of the drill a is pressed strongly against the reinforcing plate x by utilizing the leverage. Since the drill aid 1 is suspended from the object and the weight of the drill is not applied to the operator, the drill aid 200 described above (see FIG. 8) can be used. The drill a can be pressed against the reinforcing plate x with much less human power than when the bolts are drilled by directly pressing against the reinforcing plate (see FIG. 7).

Further, since the operation of drilling the bolt hole can be performed only by pulling the operation end B downward, the operation can be performed in an easy posture. Therefore, the work load of the worker who drills the bolt hole is greatly reduced. As a synergistic effect in which the work load is greatly reduced, the worker can perform the work of drilling a plurality of bolt holes in a short time, so that the work efficiency can be greatly improved.

Further, in the drill aid 1 of this embodiment, since the operating rod 2 is slidable and the support column is pivotable with respect to the support 4, the drill b The tip can be accurately applied to the drilling position of the bolt hole, and can cope with various situations. Furthermore, even if the length of the drill b attached to the tip of the drill a varies depending on the size of the bolt hole, and the drill b cannot be vertically applied to the reinforcing plate, the support 4 can be freely rotated by rotating the support 4. The height can be adjusted and the operability is very good.

Further, since the chips are sucked by using the exhaust air of the drill a to prevent the chips from being applied to the worker, the worker can work safely without harming the health of the worker. In addition, the heated chips do not burn the skin due to hitting the skin. Further, since the worker can work with light clothing, the work load can be considerably reduced especially in summertime or the like.

The reinforcing plate x of this embodiment corresponds to an object to be drilled by the drill of the present invention, and the beam corresponds to an object immovable with respect to the object. Further, the drill a, the tube a2, the air feed pipe 508, the feed portion 502, and the discharge portion 504 of the present embodiment correspond to the suction means of the present invention, and the drill peripheral portion 500 corresponds to the drill cover.
