Hereinafter, a guide device according to an embodiment of the present invention will be described with reference to the drawings. In addition, the following embodiment is only an example after all, and the guiding device of the present invention is of course not limited to the following embodiment.

As shown in FIG. 1, the guide device 1 of the present embodiment can be used when the drill bit DB of the electric drill D is used for drilling. The guide device 1 can be used to align the drill bit DB at the center of the thickness direction TD when a hole for embedding a door latch member or the like is formed in a door panel B such as a door opening or closing door. position. In addition, in this embodiment, the guide device 1 is worn Although the hole object is a door panel B such as an opening and closing door or a sliding door, the hole object is not particularly limited as long as it is a plate-shaped member having a predetermined thickness.

The electric drill D is a drill driver that makes the drill bit DB rotate around the drill axis Ax1. The electric drill D has a connection part D1 that can be connected to the drill bit DB. The drill bit DB has a base end (shank) DB1 connected to the connecting portion D1, and a cutting edge DB2 of the drill bit 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 punched from the front end DB3 (refer to FIG. 2) of the drill bit DB by rotating the drill bit DB around the drill axis AX1. In this specification, the base end portion DB1 of the drill bit DB refers to the entire end portion side of the cutting blade DB2 where the drill bit DB is not formed, and does not refer to only the portion connected to the connection portion D1 of the electric drill D. In addition, the shape or structure of the electric drill D and the drill bit DB are not particularly limited, and known electric drills and drill bits can be used.

As shown in FIGS. 1 and 2, the guide device 1 is provided with an attachment portion 2, a guide portion 3, a guided portion 4, and an engaging portion 5.

The mounting part 2 is a part where the base end DB1 of the drill DB is mounted. The mounting part 2 holds the drill bit DB so that the drill bit DB mounted on the mounting part 2 can be rotated by the electric drill D. The structure of the mounting portion 2 may be any one that can hold the drill bit DB to rotate, and the structure is not limited. In the present embodiment, as shown in FIG. 3, the mounting portion 2 includes a bearing portion 21 and a cylindrical member 22 that is rotatable with respect to the bearing portion 21 around the drill shaft Ax1 and can be inserted into the base end portion DB1 of the drill bit DB. In addition, in this embodiment, the mounting part 2 is provided in the 1st base member BS mentioned later.

The bearing portion 21 has a bearing not shown. In this embodiment, the bearing part 21 is provided in the recessed part formed by the 1st base member BS. The bearing portion 21 has an insertion hole 21a through which the cylindrical member 22 can be inserted in the direction in which the drill shaft Ax1 extends (hereinafter referred to as the axial direction). The bearing of the bearing part 21 is connected to the cylindrical member 22 inserted by the insertion hole 21a.

The cylindrical member 22 is formed in a cylindrical shape having a hollow opening at both ends in the axial direction, and as shown in FIG. 3, the base end portion DB1 of the drill DB is inserted. In addition, the length of the cylindrical member 22 in the axial direction is set such that, among the base end portion DB1 of the drill DB, the portion where the connecting portion D1 of the electric drill D is inserted is exposed from the cylindrical member 22.

The cylindrical member 22 is provided so as to be rotatable in the mounting portion 2. In addition, with respect to the bearing portion 21, the cylindrical 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 bit DB; and is configured such that when the drill bit DB is rotated by the electric drill D, the drill bit DB and the cylindrical member 22 rotate around the drill shaft Ax1.

In this embodiment, the cylindrical member 22, as shown in Figures 3 and 4(a), has a threaded portion 221 provided on one end of the cylindrical member 22, adjacent to and connected to the threaded portion 221 in the axial direction The rotating part 222 on the bearing part 21 and the rotating stop part 223 provided on the other end side of the cylindrical member 22.

The rotating part 222 is formed in an approximately cylindrical shape and is engaged with the bearing of the bearing part 21. The screw part 221 is joined to the cylindrical member 22 and the drill bit DB as shown in FIG. As shown in FIG. 3, the cylindrical member 22 and the drill bit DB rotate integrally by screwing together the fastening member N, such as a nut member, and the screw part 221.

In this embodiment, as shown in FIG. 4(a), the threaded 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 this embodiment, by fastening the fastening member N to the male threaded portion 221b of the cylindrical member 22, the drill bit DB can be attached to the mounting portion 2.

The male screw portion 221b is formed on the outer periphery of the screw portion 221. The male screw part 221b is screwed with a female screw part formed in the fastening member N (refer to FIG. 3). The screw part 221 is formed with a slit 221a along the axial direction, and is configured such that the diameter of the screw part 221 becomes narrow when the fastening member N is screwed to the male thread part 221b of the screw part 221. Therefore, when the fastening member N is screwed In the screwing portion 221, the interval between the slits 221a is narrowed, and the base end portion DB1 of the drill bit DB to be inserted is pressed from the outer peripheral side. Thereby, the drill bit DB is fixed to the cylindrical member 22.

In addition, in the present embodiment, the cylindrical member 22 has a designated tool T such as a wrench on the other end side in the axial direction (see FIG. 4(b)), and a rotation stop portion 223 that can be engaged. As shown in FIG. 4(b), when the fastening member N is screwed or the screw is released, the rotation stop portion 223 is held by the tool T. Thereby, the drill bit DB can be easily detached from the mounting part 2. Therefore, for example, when the diameter of the cutting blade DB2 of the drill DB is changed due to the size of the metal fitting attached to the door panel B, the replacement operation of the drill DB becomes easier. In addition, in this embodiment, as shown in FIGS. 1 and 3, the base end DB1 of the drill bit DB penetrates the cylindrical member 22 and is directly connected to the connection part D1 of the electric drill D. Therefore, there is no need to provide the mounting part 2 A member for connecting the connecting portion D1 of the electric drill D (a member having the base end DB1 of the drill bit DB and the same shape). In addition, the existing assembly of the drill bit DB and the electric drill D can be used in the guide device 1 as it is, which is very economical. For example, when the mounting portion 2 is provided with a member (a member having the same shape as the base end portion DB1 of the drill DB) for connecting the connecting portion D1 of the electric drill D described above, when the assembly of the drill DB and the electric drill D is changed , Can’t correspond with the same guiding device. However, in this embodiment, since the drill bit DB penetrates the cylindrical member 22, the same guide device 1 can be used even if the assembly of the drill bit DB and the electric drill D is changed.

In addition, in this embodiment, two slits 221a are provided in the peripheral direction, but the number of slits 221a may be one or plural. In addition, in this embodiment, although the fastening member N is a nut, the fastening member N is not limited to a nut. Moreover, in this embodiment, the fastening member N is provided with the locknut N2 adjacent to the axial direction.

As shown in FIG. 4( b ), the rotation stop portion 223 has flat end surfaces parallel to each other on the outer periphery of the other end side of the cylindrical member 22, and the rotation stop is performed by a tool T such as a wrench. However, as long as the shape or structure of the rotation stop portion 223 can be used for fastening the member N When tightening, the cylindrical member 22 can be restrained from rotating around the shaft by a designated tool, and it may have a hexagonal shape or the like, or other shapes.

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

The through hole 4a is inserted (refer to FIGS. 1 and 2). In this embodiment, the guided portion 4 is provided with a pair on the second base member BS2; the pair of guide portions 3 move stably in the axial direction by moving along the pair of guided portions 4. More specifically, the drill bit DB and the cylindrical member 22 are rotated around the drill shaft Ax1 due to the electric drill D. When the door panel B is perforated, the electric drill D, the drill bit DB, the first base member BS and the guide 3 are relative to The second base member BS2 moves in the direction in which the door panel B is perforated in the axial direction (hereinafter referred to as the perforation direction)

. At this time, because the guide portion 3 is guided by the guide portion 4, the first base member BS is difficult to swing and can be punched straight.

In addition, the guiding portion 3 and the guided portion 4 are not limited to the illustrated aspect. In this embodiment, although the guide portion 3 is configured to move relatively with respect to the second base member BS2, the guide portion 3 may be configured to move relatively with respect to the first base member BS. Specifically, the guide portion 3 of the first base member BS may be mounted so as to be movable in the axial direction with respect to the through hole H (refer to FIG. 3) inserted, or the guide portion 3 may be installed. 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-mentioned operation can be performed. In addition, the guide portion may be made as a guide groove provided in a housing containing the drill bit DB, or the guided portion may be made as a protrusion that engages with the guide groove. In addition, the guide part may be made into a hollow cylindrical body, or the guided part may be made into a member that moves inside the hollow cylindrical body. In addition, in this embodiment, the guided portion 4 and the engaging portion 5 are provided on the second base member BS2, and the guided portion 4 and the engaging portion 5 are formed integrally; however, it may be configured to be guided The part 4 and the engaging part 5 form a separate entity.

In addition, in this embodiment, as shown in FIGS. 1 and 2, the guide portion 3 is provided with a movement that can move along the extending direction of the guide portion 3 and can be held at a specified position in the extending direction of the guide portion 3. Component 6. The moving member 6 is provided with a moving member main body 61 movably attached to the guide portion 3 and a fixing member 62 that can be fixed at a predetermined position with respect to the guide portion 3. The shape or structure of the moving member body 61 can be appropriately changed in accordance with the shape and structure of the guide 3. In the present embodiment, the moving member main body 61 is an annular member capable of moving the outer circumference of the rod-shaped guide 3 in the axial direction. The fixing member 62 fixes the moving member main body 61 moved to a specified position to a specified position. The fixing member 62 may be any that can fix the moving member body 61, and its shape or structure is not particularly limited. In this embodiment, the fixing member 62 is crimped to the moving The outer periphery of the movable member body 61 is a screw member that restrains the movement of the movable member body 61. In this embodiment, as shown in Figs. 1 and 2, the moving member 6 is provided on a pair of guide portions 3, respectively.

By allowing the guided portion 4 to abut against the moving member 6, the movement of the drill DB can be regulated. By regulating the relative movement of the movement restriction member 6 with respect to the guided portion 4 of the guide portion 3, it is possible to regulate and restrict the tip DB3 of the drill bit DB to protrude beyond the abutment portion 51 of the engagement portion 5 to be described later. In this case, after the drill bit DB is connected to the guide device 1, since the guide portion 3 is restricted by the guide portion 4 (the second base member BS2) sliding rule, it is possible to prevent the bit DB from cutting edge Exceeding the contact portion 51 and protruding causes the operator to be injured. Specifically, the drill bit DB is mounted on the mounting portion 2, and the front end DB3 of the drill bit DB does not pass over the contact portion 51 (the state shown in FIGS. 1 and 2), so that it moves along the lower side of FIG. 1 The moving member 6 moved by the guide part 3 abuts or approaches the guided part 4 (refer to the two-dot chain line in 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 while moving to the position shown 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 punching direction, the moving member 6 abuts against the guided portion 4 in the axial direction. Therefore, the movement of the drill bit DB in the perforation direction from the state shown in Fig. 1 is restricted by the specification. Therefore, the moving member 6 serves as a stopper when the electric drill D is not in use, so that the operator can be prevented from being injured. In addition, 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 part 3 on the lower side of FIG. 1.

In addition, the moving member 6 limits the relative movement of the guided portion 4 of the guide 3 to a specified range, and limits the protrusion amount of the tip DB3 of the drill DB from the contact portion 51 in the punching direction. The specification is limited to the specified amount, and the piercing depth of the drill DB can also be adjusted. In this case, when the drill bit DB of the electric drill D is used for piercing, the guide part 3 (the first base member BS) will also move with the piercing direction of the drill bit DB, and relative to the guided part 4 in the piercing direction mobile. The guide 3 is set to move a specified amount in the drilling direction together with the drill DB, and then set The moving member 6 placed in the guide portion 3 abuts against the end surface of the guided portion 4 in the axial direction. Therefore, when the drill DB is pierced from the position shown in FIG. 1, after piercing to a specified depth, the guided portion 4 abuts the moving member 6, so the guiding portion 3 (first base member BS) and The drill bit DB will not move further in the perforation direction. Therefore, in Fig. 1, the distance between the moving member 6 of the upper guide 3 and the guided portion 4 is the perforation depth, and even an unskilled operator can perform the perforation on the end surface of the door panel B at a specified perforation depth. Punch. In addition, since the moving member 6 can move with respect to the guide portion 3, it can be adjusted according to the depth of the hole required: from the position shown by the solid line on the upper side of the guide portion 3 in FIG. 1 to the position 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, from the position shown by the solid line in FIG. 1 to the position shown by the two-dot chain line, and when the movable member 6 is moved, deep perforation can be performed via the movable 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, one side surface B2 and the other side surface B3 extending perpendicular to the end surface B1. Thereby, when perforating the door panel B with the electric drill D, the electric drill D is stabilized with respect to the door panel B by the guide device 1.
