本考案は彫金、ガラス彫刻、模型工作等に用いるペン型の電動ドリルに関するも のである。 The present invention relates to a pen-type electric drill used for metal engraving, glass engraving, model work, and the like.
【0002】[0002]
従来のペン型の電動ドリルとしては、例えば図4に示す如く片手で手軽に操作の できる筒胴Aの中に電池Bで回転するミニモーターCが内蔵され、ミニモーター Cの回転軸Dに略筒形で一端部には切削工具挿入穴Eを穿設し他端部にはモータ ー軸連結穴Fを穿設した工具装着軸Gが取付けられて回転する構成のものが知ら れている。 As a conventional pen-type electric drill, for example, as shown in FIG. 4, a mini-motor C rotating by a battery B is built in a cylindrical body A which can be easily operated with one hand, and is substantially mounted on a rotation axis D of the mini-motor C. There is known a cylindrical type having a configuration in which a tool mounting shaft G having a cutting tool insertion hole E formed at one end and a motor shaft coupling hole F formed at the other end is mounted and rotated.
【0003】[0003]
従来のペン型の電動ドリルでは構造が簡単で手軽に利用できる反面、切削工具挿 入穴Eの内径が筒形に形成されているために内径が一定で、直径の異なった切削 工具を用いることができない問題点を有していた。 The conventional pen-type electric drill has a simple structure and can be used easily. On the other hand, since the inside diameter of the cutting tool insertion hole E is cylindrical, it is necessary to use cutting tools with a constant inside diameter and different diameters. Had a problem that could not be done.
【0004】 本考案はこれらの問題点に鑑み、構造を簡単に改良することにより直径の異なる 切削工具も利用可能なペン型電動ドリルを提供することを目的として考案された ものである。[0004] In view of these problems, the present invention has been devised to provide a pen-type electric drill that can use a cutting tool having a different diameter by simply improving the structure.

本考案を図面に基づいて説明すると、図1及び図2において異径工具装着チャッ ク1は例えば直径約2m/m、長さ22m/mの鋼棒で伝動軸2を形成し伝動軸 2の一端部に回り止めのピン挿入穴3を直径方向に穿設した円柱形の基体4を固 着し基体4の他の一端側に内側に締付けテーパー面5を伝動軸2の軸芯と一直線 上に穿設し、外周部には締付け雄螺子6を刻設した有蓋筒状のチャック内筒7と 、内面には前記締付け雄螺子6に螺合する締付け雌螺子8を形成し一端側を内側 に縦断面ハ字形に形成して外側締付けテーパー面9を形成し、外周面に滑り止め 溝10を形成したチャック外筒11と、前記締付けテーパー面5と外側締付けテ ーパー面9内に遊嵌して双方のテーパー面で内側に押し付けられる工具締付けテ ーパー面12、12…を両端に形成し、中央部のみを連結面13で連結して図3 に示す如く工具締付けテーパー面12を切割り14で側面視4等分して形成した 切割り締付け片15からなるテーパー面による締付け手段(別名コレット式チャ ック)を形成して異径工具装着チャック1を形成し、異径工具装着チャック1の 伝動軸2を筒胴16内の工具装着軸17の切削工具挿入穴18中に挿着する。 The present invention will be described with reference to the drawings. In FIGS. 1 and 2, a chuck 1 with a different-diameter tool is formed of a steel rod having a diameter of about 2 m / m and a length of 22 m / m. At one end, a columnar base 4 having a pin insertion hole 3 for preventing rotation in the diameter direction is fixed, and a taper surface 5 is tightened inward at the other end of the base 4 so that a tapered surface 5 is aligned with the axis of the transmission shaft 2. The outer peripheral portion is formed with a cylindrical inner chuck 7 having a closed male screw 6 engraved thereon, and the inner female surface is formed with a female screw 8 which is screwed to the male screw 6 at one end. And a chuck outer cylinder 11 having an outer clamping tapered surface 9 formed with a vertical cross-sectional C-shape and a non-slip groove 10 formed on the outer peripheral surface, and loosely fitting into the clamping tapered surface 5 and the outer clamping taper surface 9. Tooling taper surface 12 which is pressed inward by both tapered surfaces 12 are formed at both ends, and only the central portion is connected by a connecting surface 13 to form a cutting fastening piece 15 which is formed by dividing the tool tightening tapered surface 12 into four by a cutting 14 as shown in FIG. A clamping means (also known as a collet type chuck) by a tapered surface is formed to form a chuck 1 for mounting a tool having a different diameter, and the power transmission shaft 2 of the chuck 1 for mounting a tool having a different diameter is connected to a cutting tool for a tool mounting shaft 17 in a barrel 16. It is inserted into the insertion hole 18.
【0007】 次に本考案を実施し使用する場合について述べると、チャック外筒11を回転さ せて締付け雌螺子8のリードによって基体4側より遠ざけると、内側の切割り締 付け片15の各工具締付けテーパー面12がチャック内筒7及びチャック外筒1 1の締付けテーパー面5及び外側締付けテーパー面9との間に隙間が生じて各工 具締付けテーパー面12は大径に拡がり、同時に内径も拡がるのでこの状態で大 径の切削工具Kを切割り締付け片15の内側に挿入し、次に前述とは反対方向に チャック外筒11を回転させて雌螺子8のリードにより基体4側に近づけると外 側締付けテーパー面9は工具締付けテーパー面12に接当してテーパー面12を 内側に押さえるので内径は小さくなって内側に挿入された切削工具Kを挾持固定 し、同時に切割り締付け片15は基体4側に押し付けられるので締付けテーパー 面5により内側の工具締付けテーパー面12も切削工具Kの軸部を挾持し強力に 固定することができ、さらに工具締付けテーパー面12、12の切割り溝巾を大 きくしておくと締付け巾が拡大し、大小径の切削工具Kの利用巾が拡大する。Next, the case where the present invention is implemented and used will be described. When the chuck outer cylinder 11 is rotated to be separated from the base 4 side by the lead of the tightening female screw 8, each of the inner split tightening pieces 15 is rotated. A gap is formed between the tool tightening taper surface 12 and the tightening taper surface 5 and the outer tightening taper surface 9 of the chuck inner cylinder 7 and the chuck outer cylinder 11, so that each tool tightening taper surface 12 expands to a large diameter, and at the same time, has an inner diameter. In this state, a large-diameter cutting tool K is inserted inside the slit fastening piece 15, and then the chuck outer cylinder 11 is rotated in a direction opposite to the above, and the lead of the female screw 8 is applied to the base 4 side. When approached, the outer tightening taper surface 9 comes into contact with the tool tightening taper surface 12 and presses the taper surface 12 inward, so that the inner diameter is reduced, and the cutting tool K inserted inside is clamped and fixed. At the same time, since the slit tightening piece 15 is pressed against the base 4 side, the inner tool tightening taper surface 12 can also hold the shaft portion of the cutting tool K firmly by the tightening taper surface 5, and furthermore, the tool tightening taper can be further improved. Increasing the width of the cutting grooves on the surfaces 12 and 12 increases the tightening width, and increases the usable width of the large and small diameter cutting tool K.
