取付部２は、ドリルビットＤＢの基端部ＤＢ１が取り付けられる部位である。取付部２は、取付部２に取り付けられたドリルビットＤＢが電動ドリルＤにより回転できるように、ドリルビットＤＢを保持する。取付部２の構造は、ドリルビットＤＢを回転可能に保持することができれば、その構造は限定されない。本実施形態では、取付部２は、図３に示されるように、軸受部２１と、軸受部２１に対してドリル軸Ａｘ１周りに回転可能であり、ドリルビットＤＢの基端部ＤＢ１を挿入可能な筒状部材２２とを備えている。なお、本実施形態では、取付部２は、後述する第一ベース部材ＢＳに設けられている。 The attachment part 2 is a part to which the base end part DB1 of the drill bit DB is attached. The attachment part 2 holds the drill bit DB so that the drill bit DB attached to the attachment part 2 can be rotated by the electric drill D. The structure of the mounting part 2 is not limited as long as the drill bit DB can be rotatably held. In the present embodiment, as shown in FIG. 3, the mounting portion 2 is rotatable around the bearing portion 21 and the drill axis Ax1 with respect to the bearing portion 21, and the base end portion DB1 of the drill bit DB can be inserted. And a cylindrical member 22. In the present embodiment, the mounting portion 2 is provided on a first base member BS described later.

軸受部２１は、図示しない軸受を有している。本実施形態では、軸受部２１は、第一ベース部材ＢＳに形成された凹部に設けられている。軸受部２１は、ドリル軸Ａｘ１が延びる方向（以下、軸方向という）に、筒状部材２２が挿通される挿通孔２１ａを有している。軸受部２１の軸受は、挿通孔２１ａに挿通された筒状部材２２と接続されている。 The bearing 21 has a bearing (not shown). In the present embodiment, the bearing 21 is provided in a recess formed in the first base member BS. The bearing portion 21 has an insertion hole 21a through which the cylindrical member 22 is inserted in a direction in which the drill axis Ax1 extends (hereinafter, referred to as an axial direction). The bearing of the bearing portion 21 is connected to the cylindrical member 22 inserted into the insertion hole 21a.

筒状部材２２は、軸方向の両端が開口した中空の筒状に形成され、図３に示されるように、ドリルビットＤＢの基端部ＤＢ１が挿通される。なお、筒状部材２２の軸方向の長さは、ドリルビットＤＢの基端部ＤＢ１のうち、電動ドリルＤの接続部Ｄ１に差し込まれる部位が筒状部材２２から露出するように設定される。 The cylindrical member 22 is formed in a hollow cylindrical shape whose both ends in the axial direction are open, and the base end DB1 of the drill bit DB is inserted therethrough as shown in FIG. The length of the cylindrical member 22 in the axial direction is set so that a portion of the base end portion DB1 of the drill bit DB that is inserted into the connection portion D1 of the electric drill D is exposed from the cylindrical member 22.

筒状部材２２は、取付部２において回転可能に設けられている。また、筒状部材２２は、軸受部２１に対して軸方向で移動しないように接続されている。筒状部材２２は、ドリルビットＤＢの基端部ＤＢ１が接続され、ドリルビットＤＢが電動ドリルＤにより回転すると、ドリルビットＤＢとともに筒状部材２２がドリル軸Ａｘ１周りに回転するように構成されている。 The tubular member 22 is rotatably provided at the mounting portion 2. The cylindrical member 22 is connected to the bearing 21 so as not to move in the axial direction. The cylindrical member 22 is configured so that the base end portion DB1 of the drill bit DB is connected thereto, and when the drill bit DB is rotated by the electric drill D, the cylindrical member 22 rotates around the drill axis Ax1 together with the drill bit DB. I have.

筒状部材２２は、本実施形態では、図３および図４（ａ）に示されるように、筒状部材２２の一端側に設けられた螺合部２２１と、螺合部２２１に軸方向で隣接し、軸受部２１に接続される回転部２２２と、筒状部材２２の他端側に設けられた回り止め部２２３とを有している。 In the present embodiment, as shown in FIGS. 3 and 4A, the cylindrical member 22 has a screw portion 221 provided on one end side of the cylindrical member 22 and an axially-movable portion. It has a rotating part 222 adjacent to and connected to the bearing part 21 and a detent part 223 provided on the other end side of the tubular member 22.

回転部２２２は、略円筒状に形成され、軸受部２１の軸受と接合される。螺合部２２１は、図３に示されるように、筒状部材２２とドリルビットＤＢとを接合する。図３に示されるように、螺合部２２１にナット部材等の締結部材Ｎが螺合されることにより、筒状部材２２とドリルビットＤＢとが一体的に回転する。 The rotating part 222 is formed in a substantially cylindrical shape, and is joined to the bearing of the bearing part 21. The screw portion 221 joins the cylindrical member 22 and the drill bit DB as shown in FIG. As shown in FIG. 3, when the fastening member N such as a nut member is screwed into the screw portion 221, the cylindrical member 22 and the drill bit DB rotate integrally.

本実施形態では、図４（ａ）に示されるように、螺合部２２１は、軸方向の一端側に、軸方向に延びる少なくとも１つのスリット２２１ａと、雄ネジ部２２１ｂとを有している。本実施形態では、筒状部材２２の雄ネジ部２２１ｂに締結部材Ｎが締結されることにより、ドリルビットＤＢが取付部２に取り付けられる。 In the present embodiment, as shown in FIG. 4A, the screw portion 221 has at least one slit 221a extending in the axial direction and an external thread portion 221b at one end in the axial direction. . In the present embodiment, the drill bit DB is attached to the attachment portion 2 by fastening the fastening member N to the male screw portion 221b of the tubular member 22.

雄ネジ部２２１ｂは螺合部２２１の外周に形成されている。雄ネジ部２２１ｂには、締結部材Ｎに形成された雌ネジ部が螺合する（図３参照）。螺合部２２１には、スリット２２１ａが軸方向に沿って形成され、締結部材Ｎが螺合部２２１の雄ネジ部２２１ｂに螺合した際に、螺合部２２１の径を狭くするように構成されている。そのため、締結部材Ｎが螺合部２２１に螺合されると、スリット２２１ａの間隔が狭くなり、挿通されたドリルビットＤＢの基端部ＤＢ１は外周側から押圧される。これにより、ドリルビットＤＢが筒状部材２２に固定される。 The male screw part 221b is formed on the outer periphery of the screw part 221. A female screw formed on the fastening member N is screwed into the male screw 221b (see FIG. 3). A slit 221a is formed in the screwing portion 221 along the axial direction, and the diameter of the screwing portion 221 is reduced when the fastening member N is screwed into the male screw portion 221b of the screwing portion 221. Have been. Therefore, when the fastening member N is screwed into the screwing portion 221, the interval between the slits 221a becomes narrow, and the base end portion DB1 of the inserted drill bit DB is pressed from the outer peripheral side. Thus, the drill bit DB is fixed to the tubular member 22.

また、本実施形態では、筒状部材２２は、軸方向の他端側に、スパナなど所定の工具Ｔ（図４（ｂ）参照）と係合可能な回り止め部２２３を有している。図４（ｂ）に示されるように、締結部材Ｎを螺合する際または螺合を解除する際に、回り止め部２２３が工具Ｔにより把持される。これにより、取付部２からドリルビットＤＢを容易に着脱することができる。したがって、たとえば、戸板Ｂに取り付ける金具のサイズによりドリルビットＤＢの切刃ＤＢ２の径を変更する際など、ドリルビットＤＢの交換作業が容易となる。また、本実施形態では、図１および図３に示されるように、ドリルビットＤＢの基端部ＤＢ１は、筒状部材２２を貫通して、電動ドリルＤの接続部Ｄ１に直接接続されるので、取付部２に電動ドリルＤの接続部Ｄ１に接続するための部材（ドリルビットＤＢの基端部ＤＢ１と同様の形状を有する部材）を設ける必要がない。また、既存のドリルビットＤＢと電動ドリルＤのセットをそのままガイド装置１に使用することができ、非常に経済的である。たとえば、取付部２に、上述した電動ドリルＤの接続部Ｄ１に接続するための部材（ドリルビットＤＢの基端部ＤＢ１と同様の形状を有する部材）を設けた場合、ドリルビットＤＢと電動ドリルＤのセットが変わった場合、同じガイド装置では対応できない。しかし、本実施形態では、ドリルビットＤＢが筒状部材２２を貫通するため、ドリルビットＤＢと電動ドリルＤのセットが変わっても、同じガイド装置１を使用することができる。 Further, in the present embodiment, the cylindrical member 22 has, on the other end side in the axial direction, a detent portion 223 that can be engaged with a predetermined tool T such as a spanner (see FIG. 4B). As shown in FIG. 4B, when screwing or unscrewing the fastening member N, the detent part 223 is gripped by the tool T. Thereby, the drill bit DB can be easily attached to and detached from the attachment portion 2. Therefore, for example, when changing the diameter of the cutting edge DB2 of the drill bit DB according to the size of the metal fitting to be attached to the door plate B, the work of replacing the drill bit DB becomes easy. Further, in the present embodiment, as shown in FIGS. 1 and 3, the base end portion DB1 of the drill bit DB penetrates the cylindrical member 22 and is directly connected to the connection portion D1 of the electric drill D. In addition, there is no need to provide a member (a member having the same shape as the base end portion DB1 of the drill bit DB) for connecting to the connection portion D1 of the electric drill D in the mounting portion 2. In addition, the existing set of the drill bit DB and the electric drill D can be used for the guide device 1 as it is, which is very economical. For example, when a member (a member having the same shape as the base end portion DB1 of the drill bit DB) for connecting to the connection portion D1 of the above-described electric drill D is provided in the mounting portion 2, the drill bit DB and the electric drill are provided. When the set of D changes, the same guide device cannot cope. 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 set of the drill bit DB and the electric drill D is changed.

なお、本実施形態では、スリット２２１ａは、周方向に２つ設けられているが、スリット２２１ａの数は、１つであっても、複数であってもよい。また、本実施形態では、締結部材Ｎはナットであるが、締結部材Ｎはナットに限定されない。また、本実施形態では、締結部材Ｎに軸方向で隣接して緩み止めナットＮ２が設けられている。 In the present embodiment, two slits 221a are provided in the circumferential direction, but the number of slits 221a may be one or more. In the present embodiment, the fastening member N is a nut, but the fastening member N is not limited to a nut. In the present embodiment, a locking nut N2 is provided adjacent to the fastening member N in the axial direction.

回り止め部２２３は、筒状部材２２の他端側において、図４（ｂ）に示されるように、外周に互いに平行な平端面が形成され、スパナ等の工具Ｔにより回り止めがなされている。しかし、回り止め部２２３の形状や構造は、締結部材Ｎの締結時に、所定の工具により筒状部材２２が軸周りに回転することを抑制することができれば、六角形状等、他の形状であってもよい。 As shown in FIG. 4B, the rotation preventing portion 223 has flat end surfaces parallel to each other on the outer periphery at the other end side of the cylindrical member 22, and is stopped by a tool T such as a spanner. . However, the shape and structure of the rotation preventing portion 223 may be other shapes such as a hexagonal shape if the rotation of the cylindrical member 22 around the axis by a predetermined tool can be suppressed when the fastening member N is fastened. You may.

案内部３は、図１および図２に示されるように、ドリルビットＤＢのドリル軸Ａｘ１に略平行な方向に沿って延びる、被案内部４が案内される部位である。案内部３は、本実施形態では、図１および図２に示されるように、第一ベース部材ＢＳから係合部５に向かってドリル軸Ａｘ１に略平行に延びている。案内部３は、互いに平行なロッド状の部材として示されている。 As shown in FIGS. 1 and 2, the guide portion 3 is a portion that extends along a direction substantially parallel to the drill axis Ax1 of the drill bit DB and is guided by the guided portion 4. In the present embodiment, the guide portion 3 extends substantially parallel to the drill axis Ax1 from the first base member BS toward the engagement portion 5, as shown in FIGS. The guides 3 are shown as rod-shaped members parallel to each other.

被案内部４は、ドリルビットＤＢの回転による戸板Ｂの穿孔に伴って、案内部３に沿って相対移動する。ここで、相対移動とは、被案内部４と案内部３との間の相対的な移動をいい、案内部３が被案内部４に対して移動してもよいし、被案内部４が案内部３に対して移動してもよいし、案内部３と被案内部４との両方が移動してもよい。被案内部４は、案内部３に対して移動可能に取り付けられている。被案内部４は、ロッド状の案内部３に対して摺動可能に取り付けられ、ドリル軸Ａｘ１と平行に移動する。被案内部４は、本実施形態では、係合部５側の第二ベース部材ＢＳ２に設けられ、第二ベース部材ＢＳ２が案内部３に対して移動するように構成されている。なお、被案内部４は、第一ベース部材ＢＳ側に設けられて、第一ベース部材ＢＳが取付部２と連動して移動するように構成されていてもよい。 The guided part 4 relatively moves along the guide part 3 with the perforation of the door plate B by the rotation of the drill bit DB. Here, the relative movement refers to a relative movement between the guided portion 4 and the guiding portion 3, and the guiding portion 3 may move with respect to the guided portion 4, or the guided portion 4 may move relative to the guided portion 4. The guide unit 3 may move, or both the guide unit 3 and the guided unit 4 may move. The guided portion 4 is movably attached to the guide portion 3. The guided portion 4 is slidably attached to the rod-shaped guide portion 3 and moves parallel to the drill axis Ax1.

However, the guide portion 3 may be configured to move relative to the first base member BS. Good. Specifically, the guide portion 3 is attached to the through hole H (see FIG. 3) through which the guide portion 3 of the first base member BS is inserted so as to be movable in the axial direction, and the guide portion is attached to the second base member BS2. 3 may be fixed at one end. Also 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, for example, a guide groove provided in a casing accommodating the drill bit DB, and the guided portion may be a projection that engages with the guide groove. Further, the guide portion may be a hollow cylindrical body, and the guided portion may be a member that moves inside the hollow cylindrical body. In the present embodiment, the guided portion 4 and the engaging portion 5 are provided on the second base member BS2, and are formed integrally with the guided portion 4 and the engaging portion 5. It may be configured separately from the engaging portion 5.

また、本実施形態では、図１および図２に示されるように、案内部３に、案内部３の延在方向に沿って移動可能であり、案内部３の延在方向で所定の位置で保持可能な移動部材６を備えている。移動部材６は、案内部３に移動可能に取り付けられる移動部材本体６１と、案内部３に対して所定の位置で固定可能な固定部材６２とを備えている。移動部材本体６１の形状や構造は、案内部３の形状および構造に応じて適宜変更される。本実施形態では、移動部材本体６１は、ロッド状の案内部３の外周を軸方向に移動する環状部材である。固定部材６２は、所定の位置に移動した移動部材本体６１を所定の位置で固定する。固定部材６２は、移動部材本体６１を固定することができれば、その形状や構造は特に限定されない。本実施形態では、固定部材６２は、移動部材本体６１の外周に圧接して移動部材本体６１の移動を抑制するネジ部材である。本実施形態では、図１および図２に示されるように、移動部材６は一対の案内部３にそれぞれ設けられている。 Further, in the present embodiment, as shown in FIGS. 1 and 2, the guide portion 3 is movable along the direction in which the guide portion 3 extends, and at a predetermined position in the direction in which the guide portion 3 extends. A movable member 6 that can be held is provided. The moving member 6 includes 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 and structure of the moving member main body 61 are appropriately changed according to the shape and structure of the guide portion 3. In the present embodiment, the moving member main body 61 is an annular member that moves in the axial direction on the outer periphery of the rod-shaped guide portion 3. The fixing member 62 fixes the moving member main body 61 moved to a predetermined position at a predetermined position. The shape and structure of the fixing member 62 are not particularly limited as long as the moving member main body 61 can be fixed. In the present embodiment, the fixing member 62 is a screw member that presses against the outer periphery of the moving member main body 61 and suppresses the movement of the moving member main body 61. In the present embodiment, as shown in FIGS. 1 and 2, the moving member 6 is provided on each of the pair of guides 3.

移動部材６に被案内部４が当接することにより、ドリルビットＤＢの移動が規制される。移動部材６が、案内部３の被案内部４に対する相対移動を規制することにより、ドリルビットＤＢの先端ＤＢ３が、後述する係合部５の当接部５１を越えて穿孔方向に突出することを規制することができる。この場合、ガイド装置１にドリルビットＤＢが接続された後、案内部３が被案内部４（第二ベース部材ＢＳ２）に対してスライドすることが規制されるので、ドリルビットＤＢの刃先が当接部５１を越えて突出して作業者が怪我をすることを防止することができる。具体的には、ドリルビットＤＢを取付部２に取り付け、ドリルビットＤＢの先端ＤＢ３が当接部５１を越えない状態（図１および図２に示される状態）で、図１の下方側の案内部３に沿って移動する移動部材６を、被案内部４に当接させるか近付ける（図１の二点鎖線参照）。図１の下方側の案内部３において移動部材６が二点鎖線で示される位置まで移動した状態で案内部３に対して固定され、案内部３が被案内部４（第二ベース部材ＢＳ２）に対して穿孔方向に移動しようとすると、移動部材６が被案内部４と軸方向で当接する。そのため、ドリルビットＤＢは、図１に示される状態から、穿孔方向に移動することが規制される。したがって、移動部材６が電動ドリルＤの不使用時におけるストッパとなり、作業者の怪我を防止することができる。なお、電動ドリルＤを使用する際は、図１の下方側の案内部３に沿って、移動部材６を実線で示される位置まで移動させればよい。 When the guided part 4 abuts on the moving member 6, the movement of the drill bit DB is restricted. The movement member 6 regulates the relative movement of the guide portion 3 with respect to the guided portion 4, so that the tip DB3 of the drill bit DB projects beyond the contact portion 51 of the engagement portion 5 described later in the drilling direction. Can be regulated. In this case, after the drill bit DB is connected to the guide device 1, the sliding of the guide portion 3 with respect to the guided portion 4 (the second base member BS2) is restricted, so that the cutting edge of the drill bit DB is applied. It is possible to prevent the worker from being injured by projecting beyond the contact portion 51. Specifically, the drill bit DB is mounted on the mounting portion 2, and the lower end of FIG. 1 is guided in a state where the tip DB3 of the drill bit DB does not exceed the contact portion 51 (the state shown in FIGS. 1 and 2). The moving member 6 that moves along the portion 3 is brought into contact with or near the guided portion 4 (see a two-dot chain line in FIG. 1). The moving member 6 is fixed to the guide portion 3 in a state where the moving member 6 has moved to the position shown by the two-dot chain line in the lower guide portion 3 in FIG. 1, and the guide portion 3 is guided by the guided portion 4 (second base member BS2). The moving member 6 comes into contact with the guided portion 4 in the axial direction when the moving member 6 is to be moved in the drilling direction. Therefore, the movement of the drill bit DB in the drilling direction from the state shown in FIG. 1 is restricted. Therefore, the moving member 6 serves as a stopper when the electric drill D is not used, so that injury to the operator can be prevented. When using the electric drill D, the moving member 6 may be moved to the position shown by the solid line along the guide portion 3 on the lower side in FIG.

また、移動部材６は、案内部３の被案内部４に対する相対移動の移動量を所定の範囲に規制することにより、ドリルビットＤＢの先端ＤＢ３の、穿孔方向で当接部５１からの突出量を所定量に規制して、ドリルビットＤＢによる穿孔深さを調整することもできる。この場合、電動ドリルＤのドリルビットＤＢにより穿孔を行うと、ドリルビットＤＢの穿孔方向の移動に伴い、案内部３（第一ベース部材ＢＳ）も被案内部４に対して穿孔方向に移動する。案内部３がドリルビットＤＢとともに、穿孔方向に所定の量移動した後、案内部３に設けられた移動部材６が被案内部４の軸方向の端面に当接する。これにより、ドリルビットＤＢが図１に示される位置から穿孔を行うと、所定の深さまで穿孔した後、被案内部４と移動部材６とが当接して、案内部３（第一ベース部材ＢＳ）およびドリルビットＤＢは、それ以上穿孔方向に移動しない。そのため、図１において上側の案内部３に設けられた移動部材６と被案内部４との間の距離が穿孔深さとなり、熟練していない作業者でも所定の穿孔深さで戸板Ｂの端面に穴をあけることができる。また、移動部材６は案内部３に対して移動することができるため、必要な穴の深さに応じて、図１の上側の案内部３に実線で示される位置から二点鎖線で示される位置へと移動部材６の位置を調整することにより、ドリルビットＤＢによる穿孔深さを容易に調整することができる。たとえば、図１において実線で示された位置から二点鎖線で示される位置へと移動部材６を移動させると、移動部材６と戸板Ｂの端面Ｂ１により深く穿孔することができる。 Further, the moving member 6 restricts the moving amount of the relative movement of the guide portion 3 with respect to the guided portion 4 within a predetermined range, so that the distal end DB3 of the drill bit DB projects from the contact portion 51 in the drilling direction. Can be regulated to a predetermined amount to adjust the depth of drilling by the drill bit DB. In this case, when drilling is performed by the drill bit DB of the electric drill D, the guide portion 3 (first base member BS) also moves in the drilling direction with respect to the guided portion 4 as the drill bit DB moves in the drilling direction. . After the guide part 3 moves by a predetermined amount in the drilling direction together with the drill bit DB, the moving member 6 provided on the guide part 3 comes into contact with the axial end face of the guided part 4. Thereby, when the drill bit DB pierces from the position shown in FIG. 1, after piercing to a predetermined depth, the guided part 4 and the moving member 6 come into contact with each other, and the guide part 3 (the first base member BS) ) And the drill bit DB do not move further in the drilling direction. Therefore, the distance between the moving member 6 provided on the upper guide portion 3 and the guided portion 4 in FIG. 1 is the perforation depth, and even an unskilled operator can obtain the end face of the door plate B at a predetermined perforation depth. Can be drilled in Further, since the moving member 6 can move with respect to the guide portion 3, it is indicated by a two-dot chain line from the position indicated by the solid line in the upper guide portion 3 in FIG. 1 according to the required depth of the hole. By adjusting the position of the moving member 6 to the position, the depth of drilling by the drill bit DB can be easily adjusted. For example, when the moving member 6 is moved from the position indicated by the solid line to the position indicated by the two-dot chain line in FIG. 1, the moving member 6 and the end surface B1 of the door plate B can be perforated more deeply.

係合部５は、図１に示されるように、戸板Ｂの穿孔時に、戸板Ｂに係合する。具体的には、係合部５は、戸板Ｂの端面Ｂ１と、端面Ｂ１に対して垂直に延びる一方の面Ｂ２および他方の面Ｂ３に係合する。これにより、電動ドリルＤによる戸板Ｂの穿孔時に、ガイド装置１を介して電動ドリルＤを戸板Ｂに対して安定させる。 As shown in FIG. 1, the engaging portion 5 engages with the door plate B when the door plate B is pierced.
