The drill DB has a cutting edge DB2 that is connected to a base end portion (shank) DB1 of the connecting portion D1 and a drill DB. The base end portion DB1 of the drill bit DB is a connection portion D1 connected to the electric drill D, and the end surface B1 of the door panel B is perforated from the front end DB3 (see FIG. 2) of the drill DB by rotating the drill DB around the drill shaft AX1. In the present specification, the base end portion DB1 of the drill DB refers to the entire end portion side of the cutting edge DB2 in which the drill DB DB is not formed, and does not mean only the portion connected to the connection portion D1 of the electric drill D. Further, the shape or configuration of the electric drill D and the drill DB DB are not particularly limited, and a known electric drill and a drill can be used.

As shown in FIGS. 1 and 2 , the guiding device 1 includes a mounting portion 2 , a guiding portion 3 , a guided portion 4 , and an engaging portion 5 .

The mounting portion 2 is attached to a portion of the base end portion DB1 of the drill DB. The mounting portion 2 holds the drill DB so that the drill DB attached to the mounting portion 2 can be rotated by the electric drill D. The structure of the mounting portion 2 is not limited as long as it can keep the drill DB rotatable. In the present embodiment, the mounting portion 2 includes a bearing portion 21, a cylindrical member 22 that is rotatable about the drill shaft Ax1 with respect to the bearing portion 21, and can be inserted into the base end portion DB1 of the drill DB. Further, in the present embodiment, the mounting portion 2 is provided in a first base member BS which will be described later.

The bearing portion 21 has a bearing (not shown). In the present embodiment, the bearing portion 21 is provided on the recess formed by the first base member BS. The bearing portion 21 has an insertion hole 21a through which the tubular member 22 can be inserted in a direction in which the drill shaft Ax1 extends (hereinafter referred to as an axial direction). The bearing of the bearing portion 21 is connected to the tubular member 22 through which the insertion hole 21a is inserted.

The tubular member 22 is formed in a hollow cylindrical shape in which both ends in the axial direction are open, and the base end portion DB1 of the drill DB is inserted as shown in FIG. 3 . Further, the length of the tubular member 22 in the axial direction is set such that the portion into which the connecting portion D1 of the electric drill D is inserted is exposed from the tubular member 22 in the proximal end portion DB1 of the drill DB.

The tubular member 22 is provided to be rotatable in the mounting portion 2. Further, with respect to the bearing portion 21, the tubular member 22 is connected so as not to move in the axial direction. The cylindrical member 22 is connected to the base end portion DB1 of the drill DB; and when the drill bit DB is rotated by the electric drill D, the drill DB DB rotates around the drill shaft Ax1 together with the tubular member 22.

In the present embodiment, the cylindrical member 22 has a screwing portion 221 provided on one end side of the tubular member 22, and is adjacent to the screwing portion 221 in the axial direction and connected as shown in Fig. 3 and Fig. 4(a). The rotating portion 222 of the bearing portion 21 and the rotation stopping portion 223 provided on the other end side of the tubular member 22.

The rotating portion 222 is formed in a substantially cylindrical shape and joined to the bearing of the bearing portion 21. The screwing portion 221 is joined to the tubular member 22 and the drill DB as shown in Fig. 3 . As shown in FIG. 3, the fastening member N such as a nut member and the screwing portion 221 are screwed together to integrally rotate the tubular member 22 and the drill DB DB.

In the present embodiment, as shown in FIG. 4(a), the screw portion 221 has at least one slit 221a and a male screw portion 221b extending in the axial direction on one end side in the axial direction. In the present embodiment, the drill DB can be attached to the mounting portion 2 by fastening the fastening member N to the male screw portion 221b of the tubular member 22.

The male screw portion 221b is formed on the outer circumference of the screw portion 221 . The male screw portion 221b is screwed with a female screw portion formed in the fastening member N (see Fig. 3). The screw portion 221 is formed with a slit 221a along the axial direction, and the diameter of the screw portion 221 is narrowed when the fastening member N is screwed to the male screw portion 221b of the screw portion 221 . Therefore, when the fastening member N is screwed to the screwing portion 221, the interval between the slits 221a is narrowed, and the base end portion DB1 of the inserted drill DB DB is pressed from the outer peripheral side. Thereby, the drill bit DB is fixed to the tubular member 22.

Further, in the present embodiment, the tubular member 22 has a predetermined tool T (see FIG. 4(b)) such as a wrench or the like, and a rotatable stopper 223 that can be engaged with the other end side in the axial direction. As shown in FIG. 4(b), when the fastening member N is screwed or the screwing is released, the rotation stopper portion 223 is held by the tool T. Thereby, the drill DB can be easily detached from the mounting portion 2. Therefore, for example, when the diameter of the cutting edge DB2 of the drill DB DB is changed due to the size of the metal fitting attached to the door panel B, the replacement work of the drill DB is facilitated. Further, in the present embodiment, as shown in Figs. 1 and 3, the base end portion DB1 of the drill DB is directly connected to the connecting portion D1 of the electric drill D through the tubular member 22, so that it is not required to be provided on the mounting portion 2.

Further, it is possible to use the components of the existing drill DB DB and the electric drill D as they are for the guiding device 1, and thus it is very economical. For example, in the case where the mounting portion 2 is provided with a member for connecting the connecting portion D1 of the above-described electric drill D (a member having the same shape as the base end portion DB1 of the drill DB), in the case where the components of the drill DB and the electric drill D are changed, It cannot be matched by the same guiding device. However, in the present embodiment, since the drill DB is inserted through the tubular member 22, the same guide device 1 can be used even if the components of the drill DB and the electric drill D are changed.

Further, in the present embodiment, the slit 221a is provided in two in the peripheral direction. However, the number of the slits 221a may be one or plural. Further, in the present embodiment, the fastening member N is a nut, but the fastening member N is not limited to the nut. Further, in the present embodiment, the fastening member N is provided with the lock nut N2 adjacent to the axial direction.

As shown in FIG. 4(b), the rotation stopper portion 223 is formed with a flat end surface parallel to each other on the outer circumference of the tubular member 22, and the rotation is stopped by a tool T such as a wrench. However, the shape or structure of the rotation fixing portion 223 may be a hexagonal shape or the like as long as it is possible to suppress the rotation of the tubular member 22 around the shaft by a predetermined tool when fastening the fastening member N. It can also be other shapes.

As shown in FIGS. 1 and 2, the guide portion 3 is guided along a portion guided by the guided portion 4 that extends approximately parallel to the direction of the drill axis Ax1 of the drill DB. In the present embodiment, as shown in FIGS. 1 and 2, the guide portion 3 extends from the first base member BS toward the engaging portion 5 approximately parallel to the drill axis Ax1. The guide portion 3 is a rod-shaped member that is displayed parallel to each other.

The guided portion 4 relatively moves along the guide portion 3 in accordance with the perforation of the door panel B due to the rotation of the drill DB DB. In this context, the relative movement refers to the relative movement between the guided portion 4 and the guiding portion 3; the guiding portion 3 may be moved relative to the guided portion 4; or the guided portion 4 may be relative to the guided portion 4 The guide portion 3 moves; or the guide portion 3 and the guided portion 4 may move. The guided portion 4 is attached so as to be movable with respect to the guide portion 3.

Further, the guided portion 4 may be provided on the side of the first base member BS, and the first base member BS may be moved in conjunction with the mounting portion 2.

The guided portion 4 has a through hole 4a (see FIGS. 1 and 2) through which the cylindrical rod-shaped guide portion 3 can be inserted. In the present embodiment, the guided portion 4 is provided in a pair on the second base member BS2, and the pair of guide portions 3 are stably moved in the axial direction via movement along the pair of guided portions 4. More specifically, the drill DB and the tubular member 22 are rotated around the drill shaft Ax1 by the electric drill D. When the door panel B is perforated, the electric drill D, the drill DB, the first base member BS, and the guide portion 3 are opposed to each other. The second base member BS2 is moved in a direction in which the door panel B is perforated in the axial direction (hereinafter referred to as a perforation direction). At this time, since the guide portion 3 is guided by the guide portion 4, the first base member BS is difficult to swing and can be pierced straight.

Further, the guide portion 3 and the guided portion 4 are not limited to the illustrated ones. In the present embodiment, the guide portion 3 is configured to relatively move with respect to the second base member BS2. However, the guide portion 3 may be configured to relatively move relative to the first base member BS. Specifically, the guide portion 3 of the first base member BS may be attached to the guide hole 3 so as to be movable in the axial direction with respect to the inserted through hole H (see FIG. 3 ), or the guide portion 3 may be used. One end is fixed to the second base member BS2. In this case, when the electric drill D is driven, the same operation as the above-described operation can be performed. Further, the guide portion may be formed, for example, as a guide groove provided in a casing in which the drill DB is housed, or may be a projection in which the guided portion is engaged with the guide groove. Further, the guide portion may be formed into a hollow cylindrical body, or the guided portion may be formed to move inside the hollow cylindrical body. Further, in the present embodiment, the guided portion 4 and the engaging portion 5 are provided in the second base member BS2, and the guided portion 4 and the engaging portion 5 are integrally formed; however, the guided portion 4 and the engaging portion 5 may be integrally formed. The portion 4 and the engaging portion 5 form another individual.

Further, in the present embodiment, as shown in FIGS. 1 and 2, the guide portion 3 is provided to be movable in a direction in which the guide portion 3 extends and can be held at a predetermined position in the extending direction of the guide portion 3. Member 6. The moving member 6 is provided with a moving member body 61 that is movably attached to the guiding portion 3, and a fixing member 62 that can be fixed at a predetermined position with respect to the guiding portion 3. The shape or structure of the moving member body 61 can be appropriately changed in accordance with the shape and configuration of the guide portion 3. In the present embodiment, the moving member main body 61 is an annular member that allows the outer circumference of the rod-shaped guide portion 3 to move in the axial direction. The fixing member 62 fixes the moving member body 61 moved to a specified position to a specified position. The fixing member 62 may be any one that can fix the moving member body 61, and its shape or configuration is not particularly limited. In the present embodiment, the fixing member 62 is pressed against the outer periphery of the moving member body 61 to suppress the movement of the moving member body 61. In the present embodiment, as shown in FIGS. 1 and 2, the moving members 6 are provided on the pair of guide portions 3, respectively.

By abutting the guided portion 4 against the moving member 6, the movement of the drill DB can be regulated to be restricted. By restricting the relative movement of the moving member 6 to the guided portion 4 of the guide portion 3, it is possible to restrict the tip end DB3 of the drill bit DB from protruding beyond the abutting portion 51 of the engaging portion 5 to be described later. In this case, after the drill DB is connected to the guiding device 1, since the sliding rule of the guiding portion 3 with respect to the guided portion 4 (second base member BS2) is restricted, the cutting edge of the drill DB can be prevented. Exceeding the abutment portion 51 and protruding causes the operator to be injured. Specifically, the drill DB is attached to the mounting portion 2, and the lower end side of FIG. 1 is placed in a state in which the distal end DB3 of the drill DB does not pass over the abutting portion 51 (as shown in FIGS. 1 and 2). The moving member 6 that moves the guiding portion 3 abuts or approaches the guided portion 4 (refer to the two-dot chain line of Fig. 1). In the guide portion 3 on the lower side of FIG. 1, the moving member 6 is fixed to the guide portion 3 in a state of being moved to the position indicated by the two-dot chain line, when the guide portion 3 is to be guided to the guided portion 4 ( When the second base member BS2) moves in the perforating direction, the moving member 6 abuts against the guided portion 4 in the axial direction. Therefore, the movement of the drill bit DB from the state shown in Fig. 1 in the direction of the perforation is limited by the specification. Therefore, the moving member 6 is a stopper when the electric drill D is not used, and thus it is possible to prevent an operator from being injured. Further, when the electric drill D is used, the moving member 6 can be moved to the position indicated by the solid line along the guide portion 3 on the lower side of FIG. 1 .

Further, by the moving member 6, the amount of movement of the relative movement of the guided portion 4 of the guide portion 3 is restricted to a predetermined range, and the amount of protrusion of the leading end DB3 of the drill DB from the abutting portion 51 in the perforating direction is obtained. The specification is limited to the specified amount, and the penetration depth of the drill DB can also be adjusted. In this case, when the perforation is performed by the drill DB of the electric drill D, the guide portion 3 (the first base member BS) also moves in the perforation direction with respect to the guided portion 4 in accordance with the movement of the perforation direction of the drill DB DB. mobile. After the guide portion 3 is moved by the predetermined amount in the perforating direction together with the drill DB, the moving member 6 provided in the guide portion 3 is in contact with the end surface of the guided portion 4 in the axial direction. Therefore, when the drill bit DB is perforated from the position shown in FIG. 1, after being pierced to a predetermined depth, the guided portion 4 abuts against the moving member 6, and thus the guide portion 3 (first base member BS) and The drill bit DB does not move further in the direction of perforation. Therefore, the distance between the moving member 6 and the guided portion 4 of the guide portion 3 provided on the upper side in Fig. 1 becomes the depth of the perforation, and even an unskilled operator can perform the end face of the door panel B with the specified piercing depth. Punch. Further, since the moving member 6 can move with respect to the guide portion 3, it can be adjusted according to the depth of the required hole: the guide portion 3 from the upper side of Fig. 1 is shown by the solid line as shown by the two-dot chain line. The position, as well as the position of the moving member 6, can thus easily adjust the penetration depth of the drill DB. For example, when the position indicated by the solid line in FIG. 1 is moved to the position indicated by the two-dot chain line and the moving member 6 is moved, deep penetration can be performed via the moving member 6 and the end surface B1 of the door panel B. .

As shown in FIG. 1, the engaging portion 5 is engaged with the door panel B when the door panel B is perforated. Specifically, the engaging portion 5 is engaged with the end surface B1 of the door panel B and one side surface B2 and the other side surface B3 extending perpendicularly to the end surface B1. Thereby, when the perforation of the door panel B is performed by the electric drill D, the electric drill D is stabilized with respect to the door panel B by the guide device 1.

The engaging portion 5 has an abutting portion 51, a first grip portion 52, and a second grip portion 53 as shown in FIGS. 1 and 2 . Further, in the present embodiment, the engaging portion 5 has a grip portion 54 that is gripped when the guide device 1 is engaged with the door panel B or when the door D is pierced by the electric drill D. In the present embodiment, the engaging portion 5 is provided with the second base member BS2. The second base member BS2 is attached to one end of the guide portion 3, and the drill DB is configured to be movable relative to the second base member BS2 (engagement portion 5).

The abutting portion 51 is in contact with the end surface B1 of the door panel B. In the present embodiment, the abutting portion 51 is provided on the second base member BS2, has a flat surface that abuts against the end surface B1 of the door panel 51, and has a hole portion through which the drill DB can move and the drill bit DB can pass. 51a (refer to Figure 2).

The first grip portion 52 and the second grip portion 53 are provided on the second base member BS2 and are provided on the perforation direction side with respect to the abutment portion 51. The first gripping portion 52 and the second gripping portion 53 are provided apart from each other at a predetermined interval so as to be able to grip the TD door panel B in the thickness direction of the door panel B. Although the specified interval is not particularly limited, it is preferable that the interval between the first holding portion 52 and the second holding portion 53 can be inserted into any of a plurality of types of door panels having different thicknesses. Further, both the first grip portion 52 and the second grip portion 53 are disposed such that the drill DB can pass between the first grip portion 52 and the second grip portion 53 when the drill bit DB moves in the perforating direction.

Therefore, when the guide device 1 is rotated around the drill shaft Ax1 in a state in which the starter plate B is interposed between the first grip portion 52 and the second grip portion 53, as shown in FIGS. 6 and 7, the door panel B can be used. The thickness of the first holding portion 52 is swung around the first axis Ax2, and the contact surface 52a of the first holding portion 52 and the contact surface 53a of the second holding portion 53 abut against one side B2 of the door panel B and other sides. B3. Therefore, the guiding device 1 can be engaged with the door panel B to be stably held with respect to the door panel B, and the position of the drill shaft Ax1 is aligned with the center portion in the thickness direction TD of the door panel B. When the electric drill D is driven in this state, when the drill bit DB whose position is aligned with the center portion in the thickness direction TD of the door panel B is rotated, a hole can be formed in the center portion in the thickness direction TD of the door panel B. Therefore, regardless of whether or not the operator is a skilled person, it is possible to easily form a hole in the center portion in the thickness direction TD of the door panel B by the drill DB.
