Description
【考案の詳細な説明】
この考案はガラスに比較的大きな円孔をあけるドリルの
改良に関するものである。[Detailed Description of the Invention] This invention relates to an improvement of a drill for drilling relatively large circular holes in glass.
従来のガラス用孔あけドリルは、底壁外面にシャンクを
そなえる有底円筒の開口縁をダイヤモンド刃としたもの
であり、このドリルを使用してガラスに孔をあける際、
孔が抜ける最終時点で孔縁に蛤状の欠け（はま欠け）を
生じるという欠点がある。Conventional glass drilling drills have a bottomed cylinder with a shank on the outer surface of the bottom wall, and the opening edge is a diamond blade. When using this drill to drill a hole in glass,
There is a drawback that a clam-like chip (hama-chip) occurs at the hole edge at the final point when the hole exits.
これを防止するためにガラスの両面がらこのドノルで孔
をあけるが、両面の円が一致せず、孔縁（内面）に段が
生じて研磨処理を必要とし作業が著しく煩雑である。In order to prevent this, holes are drilled on both sides of the glass using this drill, but the circles on both sides do not match and a step is created on the edge of the hole (inner surface), requiring polishing and making the work extremely complicated.
この考案は孔あけ時の上記従来の欠点を解決したもので
、その目的とするところは、ガラスの両面から孔をあけ
ても孔用円が完全に一致するドリルとするにある。This invention solves the above-mentioned conventional drawbacks when drilling holes, and its purpose is to create a drill whose hole circles perfectly match even when holes are drilled from both sides of the glass.
以下この考案の構成を添付図面に基いて説明すれば、１
は有底円筒、２は有底円筒１の底壁外面中央部にそなえ
るシャンクである。Below, the configuration of this device will be explained based on the attached drawings.
2 is a cylinder with a bottom, and 2 is a shank provided at the center of the outer surface of the bottom wall of the cylinder 1 with a bottom.
有底円筒１の開口縁はダイヤモンド刃部３にしである。The opening edge of the bottomed cylinder 1 is adjacent to the diamond blade part 3.
有底円筒１の底壁内面には中央部に、先端が開口縁（ダ
イヤモンド刃部３）から突出する芯軸４をそなえており
、この芯軸の先端は雄刃５となっている。The inner surface of the bottom wall of the bottomed cylinder 1 is provided at the center with a core shaft 4 whose tip protrudes from the opening edge (diamond blade portion 3), and the tip of this core shaft is a male blade 5.
尚図中６は芯軸４を固定するボス、７は芯軸をボスに固
定する止めねし、８は止めねじ７を線群するための、円
筒壁に形成したドライバー通し孔、９はガラス屑排出用
スリットを示す。In the figure, 6 is a boss for fixing the core shaft 4, 7 is a set screw for fixing the core shaft to the boss, 8 is a screwdriver hole formed in the cylindrical wall for grouping the set screws 7, and 9 is a glass hole. The slit for waste discharge is shown.
この考案は上記したような構造でありダイヤモンド刃部
をそなえる有底円筒（コア）の内底部中央には芯軸があ
り、芯軸の先端は雄刃になっていてこの雄刃はダイヤモ
ンド刃部より突出しているので、ガラスに円孔をあける
に当り雄刃により円の中心に孔をあけるので、ダイヤモ
ンド刃部による円孔あけは中途までに止め、次にガラス
の裏面から円孔をあけるのに前記形成された中心孔に雄
刃を挿し込むことで円孔を両面完全に一致させることが
でき、従ってあけられた円孔の孔縁ははま欠けもなく、
且つ仕上研磨の必要も全くないという効果がある。This idea has the above-mentioned structure, and there is a core shaft in the center of the inner bottom of the bottomed cylinder (core) equipped with the diamond blade, and the tip of the core shaft is a male blade, and this male blade is the diamond blade. Since it is more protruding, when making a circular hole in the glass, the male blade is used to make the hole in the center of the circle, so it is best to stop drilling the circular hole halfway through with the diamond blade and then drill the circular hole from the back of the glass. By inserting the male blade into the center hole formed above, both sides of the circular hole can be perfectly aligned, so that the edges of the circular hole are not chipped.
Another advantage is that there is no need for final polishing.
