Description
本考案は、端部が損壊したネジをワークから取り出すためのドリルに係り、特に、端部が損壊したネジに嵌合して前記ネジを回転することが可能になるドリルに関するものである。 The present invention relates to a drill for taking out a screw whose end is damaged from a workpiece, and more particularly to a drill that can be fitted to a screw whose end is damaged and rotate the screw.
一般には、ネジのヘッド部に十字形状または一字形状の溝が設けられ、しかし、ネジのヘッド部の溝がある原因で損壊されたと、一般のドライバによってネジを回転することはできなくなり、だから、図５乃至図７に示すように、ヘッド部の溝が損壊されたネジを回転するドリル６０が提案され（米国特許第6,595,730号）、このドリル６０は、エアー駆動工具または電動工具と接続するために、一端が六角断面形状を持ち、他端の端面には縦方向に沿った溝６１が二つ設けてあり、前記溝６１は、一つの削り面６２と、一つの境界面６３とから構成され、前記削り面６２の頂縁には削り縁６２１が形成され、前記境界面６３の頂縁には境界縁６３１が形成され、前記境界縁６３１と前記削り縁６２１との間には円錐形状の逃げ面６４が形成され、ネジ９０の溝９１が損壊されたヘッド部にドリル６０にある削り縁６２１を嵌合して左回ると、ネジ９０ワークからを取り出すことができる。しかしながら、これは次のような欠点があった。 In general, a cross or single-shaped groove is provided in the screw head, but if it is damaged due to the groove in the screw head, the screw cannot be rotated by a general screwdriver. As shown in FIGS. 5 to 7, a drill 60 for rotating a screw in which a groove of the head portion is damaged is proposed (US Pat. No. 6,595,730), and this drill 60 is connected to an air driven tool or an electric tool. For this purpose, one end has a hexagonal cross-sectional shape, and the end face of the other end is provided with two grooves 61 along the longitudinal direction. The groove 61 is formed by one cutting surface 62 and one boundary surface 63. A cutting edge 621 is formed on the top edge of the cutting surface 62, a boundary edge 631 is formed on the top edge of the boundary surface 63, and a cone is formed between the boundary edge 631 and the cutting edge 621. A flank 64 in the shape is formed If the groove 91 of the screw 90 turns left fitted Sharpener edges 621 in the drill 60 in the head portion that is damaged, it can be taken out from the screw 90 the workpiece. However, this has the following drawbacks.
（イ）逃げ面６４は扇形輪郭の円錐であり、逃げ面６４の外縁に近づくほど、削り縁６２１と境界縁６３１との間の距離は大きくなり、だから、ドリル６０と溝９１の嵌合深さが制限され、これにより、削り縁６２１と溝９１の握り面積は小さく、ネジ９０に梃子効果による力を完全に加えることができない。 (A) The flank 64 is a fan-shaped contour cone, and the closer to the outer edge of the flank 64, the larger the distance between the cutting edge 621 and the boundary edge 631. Therefore, the grip area of the shaving edge 621 and the groove 91 is small, and the force due to the lever effect cannot be applied to the screw 90 completely.
（ロ）ドリル６０によってネジ９０を取り出すときには、溝９１が全面的に損壊され円錐形状の窪みになった場合には、ドリル６０の前記逃げ面６４が止められてネジ９０を取り出すことができなく、なお、溝９１の頂面が損壊され円錐形状の窪みになり、そして溝９１の底面が本来の形に保持される場合には、ドリル６０が溝９１の頂面からもっと下げることができないので、ネジ９０を取り出すことができない。 (B) When the screw 90 is taken out by the drill 60, if the groove 91 is totally damaged and becomes a conical depression, the flank 64 of the drill 60 is stopped and the screw 90 cannot be taken out. If the top surface of the groove 91 is damaged and becomes a conical depression, and the bottom surface of the groove 91 is held in its original shape, the drill 60 cannot be lowered further from the top surface of the groove 91. The screw 90 cannot be removed.
上記欠点を解決するために、図８と図９に示す米国特許第7,000,501号が提案され、これは、主に、ドリル７０が頂端７２を有し、前記頂端７２の周面には縦方向に沿った溝７３が二つ設けてあり、前記各溝７３は、左回りの削り面７４と、右回りの境界面７５とから構成され、前記境界面７５と前記削り面７４の成し角度は９０度であり、前記削り面７４の頂縁は直線状の削り縁７４１であり、削り縁７４１と、ドリル７０の軸線との成し角度は３５度〜８０度程度であり、前記境界面７５の頂縁は直線状の境界縁７５１であり、前記境界縁７５１と前記削り縁７４１はほぼ互いに垂直し、前記頂端７２の周面には縦方向に沿った仕切面７６が設けてあり、前記仕切面７６が前記境界面７５と連続し、前記仕切面７６の頂縁には仕切縁７６１が形成され、前記仕切縁７６１と、前記境界縁７５１と、前記削り縁７４１と、ドリル７０の周縁とから四辺形状の逃げ面８０が形成され、前記二つの逃げ面８０はドリル７０の軸心を中心として互いに対称し、且つ前記仕切縁７６１および前記境界縁７５１と、ドリル７０の軸線との成す角度は、前記削り縁７４１と、ドリル７０の軸線との成す角度よりも小さい。 In order to solve the above-mentioned drawbacks, US Pat. No. 7,000,501 shown in FIGS. 8 and 9 is proposed. This is mainly because a drill 70 has a top end 72, and the peripheral surface of the top end 72 has a longitudinal direction. Two grooves 73 are provided, and each of the grooves 73 includes a counterclockwise cutting surface 74 and a clockwise boundary surface 75, and an angle formed between the boundary surface 75 and the cutting surface 74 is as follows. 90 °, the top edge of the cutting surface 74 is a straight cutting edge 741, the angle between the cutting edge 741 and the axis of the drill 70 is about 35 ° to 80 °, and the boundary surface 75 The boundary edge 751 is a straight boundary edge 751, the boundary edge 751 and the cutting edge 741 are substantially perpendicular to each other, and the peripheral surface of the top end 72 is provided with a partition surface 76 along the vertical direction, A partition surface 76 is continuous with the boundary surface 75, and a partition edge 761 is formed at the top edge of the partition surface 76. A quadrilateral relief surface 80 is formed from the partition edge 761, the boundary edge 751, the shaving edge 741, and the peripheral edge of the drill 70, and the two relief surfaces 80 form the axis of the drill 70. The angles of the partition edge 761 and the boundary edge 751 and the axis of the drill 70 that are symmetrical to each other as a center are smaller than the angle formed by the shaving edge 741 and the axis of the drill 70.
だから、図８と図９に示すドリルは、逃げ面８０が変化され、そして削り縁７４１と、ドリル７０の軸線との成し角度が３５度よりも大きいので、仕切縁７６１及び境界縁７５１と、ドリル７０の軸線との成し角度が縮小になり、これにより、二つの削り縁７４１の成し角度が小さくなり、ひいては頂端７２がもっと鋭くなり、そうすると、図６と図７に示すドリルよりも、ネジのヘッド部の溝の頂面からもっと下げることができ、すなわち、両者の嵌合面積は増加し、ドリルのネジに対する回転力は大きくなる。 Therefore, the drill shown in FIGS. 8 and 9 has the flank 80 changed, and the angle between the cutting edge 741 and the axis of the drill 70 is greater than 35 degrees, so that the partition edge 761 and the boundary edge 751 , The angle of formation with the axis of the drill 70 is reduced, thereby reducing the angle of formation of the two cutting edges 741, and thus the apex 72 is sharper, so that the drill shown in FIGS. However, it can be lowered further from the top surface of the groove of the head portion of the screw, that is, the fitting area between the two is increased, and the rotational force on the screw of the drill is increased.
しかしながら、ドリル７０の削り面７４は平面形状であるので、削り縁７４１は鋭くない、溝の頂面が損壊されたときには、前記削り縁７４１は溝の底面を有効に齧ることができなく、だから、ネジを取り出すことは依然として難しい。 However, since the cutting surface 74 of the drill 70 has a planar shape, the cutting edge 741 is not sharp, and when the top surface of the groove is damaged, the cutting edge 741 cannot effectively hit the bottom surface of the groove. It is still difficult to remove the screw.
本考案の主な目的は、ネジのヘッド部の損壊された溝に対する齧り力および嵌合効果が向上になり、ヘッド部の溝が損壊されたネジをワークから取り出することが容易になるドリルを提供する。 The main object of the present invention is to provide a drill that improves the twisting force and fitting effect on the damaged groove of the screw head part, and makes it easy to take out the screw with the damaged groove of the head part from the workpiece. provide.

以下、添付図面を参照して本考案の好適な実施の形態を詳細に説明する。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
本考案に係るドリル７００は、図８と図９に示すドリルを改善したものであり、主に、一つの頂端７２と、縦方向に沿った二つの溝７３とを有し、前記各溝７３は、左回りの削り面１０と、右回りの境界面７５とから構成され、前記削り面１０と、前記境界面７５との成し角度は９０度であり、前記削り面１０の頂縁は直線状の鋭い削り縁１１であり、前記削り縁１１と、ドリル７００の軸線との成す角度は３５から８０度程度であり、前記境界面７５の頂端は直線状の境界縁７５１であり、前記境界縁７５１と前記削り縁１１はほぼ互いに垂直し、前記頂端７２の周面には縦方向に沿った仕切面７６が二つ設けてあり、前記仕切面７６が前記境界面７５と連続し、前記仕切面７６の頂縁には仕切縁７６１が形成され、前記仕切縁７６１と、前記境界縁７５１と、削り縁１１と、ドリル７００の周縁とから四辺形状の逃げ面８０が形成され、前記二つの逃げ面８０はドリル７００の軸心を中心として互いに対称し、且つ前記仕切縁７６１および前記境界縁７５１と、ドリル７００の軸線との成す角度は、前記削り縁１１と、ドリル７００の軸線との成す角度よりも小さい。 A drill 700 according to the present invention is an improvement over the drill shown in FIGS. 8 and 9, and mainly includes one apex 72 and two grooves 73 along the longitudinal direction. Is composed of a left-handed cutting surface 10 and a right-handed boundary surface 75, and the angle between the cutting surface 10 and the boundary surface 75 is 90 degrees, and the top edge of the cutting surface 10 is A straight sharp cutting edge 11, an angle formed by the cutting edge 11 and the axis of the drill 700 is about 35 to 80 degrees, and a top end of the boundary surface 75 is a straight boundary edge 751, The boundary edge 751 and the cutting edge 11 are substantially perpendicular to each other, and two partition surfaces 76 are provided along the longitudinal direction on the peripheral surface of the top end 72, and the partition surface 76 is continuous with the boundary surface 75, A partition edge 761 is formed on the top edge of the partition surface 76, and the partition edge 761, A quadrilateral relief surface 80 is formed from the boundary edge 751, the cutting edge 11, and the peripheral edge of the drill 700, the two relief surfaces 80 being symmetrical to each other about the axis of the drill 700, and the partition edge An angle formed by 761 and the boundary edge 751 and the axis of the drill 700 is smaller than an angle formed by the cutting edge 11 and the axis of the drill 700.
本考案の長所は、図１と図２に示すように、削り面１０が窪んだ円弧形状を呈し、だから、削り縁１１がもっと鋭くなる。 As shown in FIGS. 1 and 2, the advantage of the present invention is that the shaving surface 10 has a concave arc shape, so that the shaving edge 11 becomes sharper.
このように、図１と図３と図４に示すように、ヘッド部の溝９１が損壊されたネジ９０をワークから取り出そうとする場合には、削り面１０が窪んだ円弧形状を呈することにより、削り縁１１がもっと鋭いカッター形態になり、だから、削り縁１１は溝９１の内壁面を齧ることが容易になり、且つ頂端７２と溝９１との嵌合面積が増加になり、これにより、ネジ９０をワークから取り出すことは容易になる。 Thus, as shown in FIGS. 1, 3, and 4, when the screw 90 in which the groove 91 of the head portion is damaged is taken out from the workpiece, the shaving surface 10 exhibits an arcuate shape. The cutting edge 11 becomes a sharper cutter, so that the cutting edge 11 can easily roll the inner wall surface of the groove 91, and the fitting area between the top end 72 and the groove 91 is increased. It is easy to remove the screw 90 from the workpiece.
また、溝９１の頂面が損壊され円錐形状の窪みになり、そして溝９１の底面が本来の形に保持される場合であっても、削り面１０が窪んだ円弧形状を呈することにより、削り縁１１がもっと鋭いカッター形態になり、だから、ドリル６０は溝９１の内壁面に齧り込むことができ、これにより、ネジ９０をワークから取り出すことが容易になる。 Further, even when the top surface of the groove 91 is damaged to form a conical depression, and the bottom surface of the groove 91 is held in its original shape, the shaving surface 10 exhibits a hollow arc shape, thereby reducing the shape of the groove 91. The edge 11 becomes a sharper cutter, so that the drill 60 can dig into the inner wall surface of the groove 91, which makes it easier to remove the screw 90 from the workpiece.
