スポツト溶接された鋼板を外すには、溶接部分
で一枚の鋼板に穴を明けると容易に外せるが薄い
鋼板に適度な穴を明けることはきわめて難しく精
密な治具あるいは施盤等の精密機械を要する。 Spot-welded steel plates can be easily removed by drilling a hole in a single steel plate at the welded area, but it is extremely difficult to drill a suitable hole in a thin steel plate and requires precision machinery such as a precision jig or lathe. .
例えば自動車用の鋼板では、0.6〜0.7mmの厚さ
の鋼板が用いられるため、二枚重ねたうちの一枚
にのみ穴明けをするには0.1mm程度の誤差しか許
されない。 For example, steel plates for automobiles use steel plates with a thickness of 0.6 to 0.7 mm, so only an error of about 0.1 mm is allowed when drilling a hole in only one of two stacked sheets.
しかも、このような穴明け加工に用いられる穿

に構成することが必要であつた。 Moreover, the punching device used for such drilling must be easily transportable and must be small and lightweight.
本発明は、このような事情から小形で軽量に構

明け加工が施せる穿孔装置を提供することを目的
としている。 In view of these circumstances, it is an object of the present invention to provide a drilling device that is compact and lightweight, and that allows the drill bit to protrude accurately to perform precise drilling.
上記の目的を達成する本発明の特徴とするとこ

およびこれに備えたキリが回転しながら軸方向に
１往復する。このようにキリの往復動は傾斜面に
よるカム作用で行なわれるため、キリを正確に一
定量を突出させることができ、所定の深さの穴明
けを正確になし得る。 With this configuration, when the device is operated, the shafts of both gears on the same axis rotate at different rotational speeds because the gear meshes with the drive side gear at a different tooth ratio. However, due to this rotation, the cam formed by the inclined surface provided at the abutment part of both shafts,
Due to the difference in rotational speed, the shafts slide relative to each other on the inclined surface, and one of the movable shafts moves in the axial direction. One rotation of the inclined surface causes one shaft and the aperture attached thereto to rotate and reciprocate once in the axial direction. Since the reciprocating movement of the drill is performed by the cam action of the inclined surface, the drill can be accurately projected by a certain amount, and a hole can be accurately drilled to a predetermined depth.

さらに、一方の軸８と他方の軸７とは衝合され
ており、この衝合部分に傾斜面１０が形成されて
カムを構成している。 Furthermore, one shaft 8 and the other shaft 7 are abutted against each other, and an inclined surface 10 is formed at this abutting portion to constitute a cam.
また、軸７，８の衝合部分は、軸心にピン１１
が嵌合されるか、あるいは一方の軸が他方の軸に
嵌挿されて、２本の軸７，８が同一軸線上に保持
されるよう構成されている。 In addition, the abutting portion of the shafts 7 and 8 has a pin 11 at the shaft center.
The two shafts 7 and 8 are held on the same axis by being fitted into each other, or by fitting one shaft into the other shaft.
他方の軸７の端部には、スラストメタル１２が
設けられると共に、回転しないようストツパー１
３を備えたスラスト受け１４が設けられて、負荷
方向に対向するよう構成されている。 A thrust metal 12 is provided at the end of the other shaft 7, and a stopper 1 is provided to prevent rotation.

スラスト受け１４は、ケース１５に螺合され外
部から回動して軸方向に移動する調整装置１６に
嵌合しており、調整装置１６の回動により軸方向
に移動可能に構成されている。 The thrust receiver 14 is fitted into an adjustment device 16 that is screwed into the case 15 and rotated from the outside to move in the axial direction, and is configured to be movable in the axial direction by the rotation of the adjustment device 16.
ケース１５は、電動機１の部分がハンドル１７
となり、一方にアーム１８が設けられており、ア
ーム１８がガイドとなつてキリ１９が設けられて

そして、キリ１９は、コレツトチヤツク２０に
よつて軸方向に移動可能な一方の軸８に取付けら

さらに傾斜面１０によるカム作用でアーム１８か
ら突出するよう構成されている。 The drill 19 is attached to one shaft 8 that is movable in the axial direction by a collector chuck 20, and is rotated together with the shaft 8 by a gear 6.
Further, it is configured to protrude from the arm 18 by the cam action of the inclined surface 10.
このような構成において、穿孔装置は、電動機
１の回転が駆動軸２のギヤー３，４を介してこれ
に噛合するギヤー５，６に伝達されると共に、ギ
ヤー５，６はそれぞれ異なる歯数で構成されてギ
ヤー３，４との歯数比が異なつていることから異
なる回転数で回転することになる。 In such a configuration, in the drilling device, the rotation of the electric motor 1 is transmitted via the gears 3 and 4 of the drive shaft 2 to the gears 5 and 6 meshing therewith, and the gears 5 and 6 each have a different number of teeth. Since the gears 3 and 4 have different tooth ratios, they rotate at different rotational speeds.
そして、ギヤー５，６によつて夫々回転する軸
７，８の衝合部に設けられた傾斜面１０によるカ
ムは、ギヤー５，６が異なる回転数で回転するこ
とから、衝合された傾斜面１０でギヤー５，６の
回転数の差によつて摺動する。 Since the gears 5 and 6 rotate at different rotational speeds, the cam formed by the inclined surface 10 provided at the abutting portion of the shafts 7 and 8 rotated by the gears 5 and 6, respectively, It slides on surface 10 due to the difference in rotational speed between gears 5 and 6.
従つて、１回転の摺動によつて軸７，８の間隔

そして、一方の軸８の端部にはコレツトチヤツ
ク２０を介してキリ１９が備えられているため、
キリ１９が軸方向に往復動することになる。 And, since a drill 19 is provided at the end of one shaft 8 via a collection chuck 20,
The drill 19 will reciprocate in the axial direction.
さらに、調整装置１６を回動させるとスラスト
受け１４が軸方向へ移動するため、軸７を軸方向
へ移動させることができ、キリ１９の往復動する
位置を軸方向へ移動させることができる。 Furthermore, since the thrust receiver 14 moves in the axial direction when the adjusting device 16 is rotated, the shaft 7 can be moved in the axial direction, and the reciprocating position of the drill 19 can be moved in the axial direction.
このようなキリ１９の往復動は、傾斜面１０に
よるカム機構で行われるため、この往復動毎にキ
リ１９をきわめて正確に一定量を突出させること
ができ、所定の深さの穴明けを正確になすことが

そして、傾斜面１０の摺動によるため1/10mm程
度の精度はきわめて容易に得ることができ、薄い
鋼板を重ね合わせてスポツト溶接しても、その一
枚の鋼板のみ確実に穴を明けることができ、他方
の鋼板に不要の穴を明けたり、また一方の鋼板に
穴の明け残しを生じるといつたことなく所定の目
的を容易に達成することができる。 Since the sliding movement of the inclined surface 10 is used, an accuracy of about 1/10 mm can be obtained extremely easily, and even if thin steel plates are overlapped and spot welded, it is possible to reliably drill a hole in only that one steel plate. This makes it possible to easily achieve the desired purpose without creating unnecessary holes in the other steel plate or leaving holes in one steel plate.
また、キリ１９の突出量は、アーム１８からの
突出量で定めれば、穿孔部分にアーム１８を強く
押圧して用いるか、あるいはアーム１８を治具で
穴明けする鋼板等に固定することにより所定の突
出量を利用することができる。 Furthermore, if the amount of protrusion of the drill 19 is determined by the amount of protrusion from the arm 18, it may be used by strongly pressing the arm 18 against the hole to be drilled, or by fixing the arm 18 to a steel plate or the like to be drilled with a jig. A predetermined amount of protrusion can be used.
キリ１９の突出量を測定するには、調整装置１
６の回動に目盛を構成してもよく、試験的に穴明
けを行い穴の深さを測定してもよく、いずれの場
合も調製装置１６を回動することで調整が容易に
なせるため、各種の厚さの鋼板等の材料に適合す
ることができる。 To measure the amount of protrusion of the drill bit 19, adjust the adjusting device 1.
A scale may be configured on the rotation of 6, or a hole may be made on a trial basis and the depth of the hole may be measured; in either case, adjustment can be easily made by rotating the preparation device 16. Therefore, it can be adapted to materials such as steel plates of various thicknesses.
キリ１９の回転数は、電動機１の回転がギヤー
４を介してギヤー６に伝達される回転数で定ま
り、キリ１９の往復動は、ギヤー５とギヤー６と
の回転数の差の数値で定まることになる。 The rotational speed of the awl 19 is determined by the rotational speed at which the rotation of the electric motor 1 is transmitted to the gear 6 via the gear 4, and the reciprocating motion of the awl 19 is determined by the difference in the rotational speed between the gears 5 and 6. It turns out.
従つて、キリ１９の回転は穿孔に都合のよい高
回転数となり、キリ１９の往復動はギヤー５，６
の回転数の差で定まるためきわめて低速度から任
意の高速度まで容易に選定することができる。 Therefore, the rotation of the drill 19 is at a high rotational speed convenient for drilling, and the reciprocating motion of the drill 19 is controlled by the gears 5 and 6.
Since it is determined by the difference in the number of rotations, it can be easily selected from extremely low speeds to arbitrary high speeds.
特に、キリ１９は、回転数に比べて往復動の速
度を遅くする必要があり、一般的には回転数を約
2000rpm、往復動を10〜100回／毎分程度にする
のが好ましく、このような機能を２個のギヤー
５，６によつてなすことは構成上きわめて小形軽
量で単純な構成になり、この種装置として効果的
である。 In particular, the reciprocating speed of the awl 19 needs to be slow compared to the rotation speed, and generally the rotation speed is approximately
It is preferable to operate at 2000 rpm and reciprocate approximately 10 to 100 times per minute.Performing this function using two gears 5 and 6 results in an extremely compact, lightweight, and simple configuration; Effective as a seed device.
キリ１９は、エンドミルを用いると薄い２枚の
鋼板の一枚にのみ穴明けをなすに都合がよく、そ
の他穴の縁部に生じるカエリ取りや、皿ネジ用の
テーパー穴等夫々に適合した種類のキリを用いる
ことができるため各種の穿孔に適合させることが
でき同様の効果が得られる。 Aperture 19 is convenient for making a hole in only one of two thin steel plates when using an end mill, and is suitable for removing burrs on the edge of other holes, tapered holes for countersunk screws, etc. Since it is possible to use a drill, it can be adapted to various types of perforations, and the same effect can be obtained.
