Description

Auf einen Spiralbohrer aufsetzbares Senkwerkzeug Die Erfindung bezieht sich auf ein auf einen Spiralbohrer aufsetzbares und gegenüber diesem axial ein- und feststellbares einteiliges Senkwerkzeug, welches es ermöglicht, unmittelbar im Anschluß an den Bohrvorgang die Kante der Bohrung zu entgraten oder anzusenken.Countersinking tool attachable to a twist drill The invention relates on a drill that can be placed on a twist drill and axially and lockable one-piece countersinking tool, which makes it possible to immediately deburring or countersinking the edge of the hole after the drilling process.

Es sind bereits Senkwerkzeuge bekannt, bei denen die aus getrennten Messern gebildete Versenkeinrichtung mittels eines zweiteiligen Spannfutters lösbar mit dem Spiralbohrer verbunden ist. Dabei greifen die Messer mit einem den Spiralbohrernuten entsprechenden schraubenförmigen Teil in diese ein und werden durch Keilflächen des Spannfutters festgespannt. Es ist aber nicht möglich, die Versenkeinrichtung bei jedem Bohrvorgang längs des Bohrers zu verschieben. Für verschiedene Bohrerlängen muß die Verbindung der beiden Werkzeuge vielmehr jedesmal gelöst und neu hergestellt werden.Countersinking tools are already known in which the separate Countersinking device formed by knives can be released by means of a two-part chuck connected to the drill bit. The knives grip with one of the spiral drill grooves corresponding helical part in this one and are by wedge surfaces of the chuck clamped. But it is not possible to use the lowering device to move along the drill bit with each drilling process. For different drill lengths the connection between the two tools must rather be loosened and re-established each time will.

Es ist auch bekannt, ein auf einen Spiralbohrer aufsetzbares einteiliges Versenkwerkzeug gegenüber dem Spiralbohrer einstellbar auszubilden und dadurch gegen Verdrehen zu sichern, daß das Senkwerkzeug in die Spannuten des Bohrers eingreift. Diese Senkwerkzeuge ermöglichen jedoch keine Zentrierung auf dem genuteten Teil des Bohrers.It is also known to have a one-piece that can be placed on a twist drill Form countersinking tool adjustable with respect to the twist drill and thus against Rotate to ensure that the countersink engages in the flutes of the drill. However, these countersinking tools do not allow centering on the grooved part of the drill.

Aufgabe der Erfindung ist es daher, eine genaue Zentrierung des Senkwerkzeugs an jeder Stelle des spiralgenuteten Bohrerteils zu ermöglichen. Dies wird dadurch erreicht, daß die Innenwand des Senkwerkzeuges mit zwei den Schneidenfasen des Spiralbohrers entsprechenden Nuten versehen ist. Hierdurch wird es möglich, das Senkwerkzeug bei jedem Bohrvorgang längs des Bohrers zu verschieben und einen genau zentrischen Rundlauf des Senkwerkzeuges zu erreichen.It is therefore the object of the invention to achieve precise centering of the countersinking tool to allow at any point of the spiral fluted drill part. This is because of this achieved that the inner wall of the countersinking tool with two of the cutting bevels of the twist drill corresponding grooves is provided. This makes it possible to use the countersink at to move along the drill with each drilling process and ensure an exactly centric runout of the countersinking tool.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in drei Figuren dargestellt. Es zeigt F i g. 1 das Senkwerkzeug an einem Spiralbohrer im Aufriß, F i g. 2 eine Draufsicht auf das Werkzeug gemäß F i g. 1, F i g. 3 eine Ansicht des Senkwerkzeuges in teilweisem Längsschnitt.In the drawing is an embodiment of the invention in three Figures shown. It shows F i g. 1 the countersink on a twist drill in Elevation, Fig. 2 shows a plan view of the tool according to FIG. 1, Fig. 3 a View of the countersinking tool in partial longitudinal section.

Auf den Spiralbohrer 1 ist das als einteiliger Ringkörper mit Schneiden 3 und 4 ausgebildete Senkwerkzeug 2 aufgeschoben und durch die Stellschrauben 5 festgehalten. Das Senkwerkzeug ist an seiner Innenfläche mit zwei spiralförmig verlaufenden Nuten 6, 7 versehen, in welche die Schneidenfasen 8 und 9 des Spiralbohrers eingreifen. Auf diese Weise ist eine spiralförmige Verschiebung der Versenkeinrichtung 2 auf dem Bohrer 1 nach Lösen der Stellschrauben leicht möglich und ein Zusammenhalten beider Werkzeuge beim Senkvorgang gewährleistet, weil die Schneidenfasen des Bohrers in die Nuten an der Innenfläche des Senkers passend eingreifen.On the twist drill 1 this is a one-piece ring body with cutting edges 3 and 4 formed countersink tool 2 pushed on and through the adjusting screws 5 held. The countersink is on its inner surface with two spirals Grooves 6, 7 are provided in which the cutting bevels 8 and 9 of the twist drill engage. In this way, the lowering device 2 is displaced in a spiral shape the drill 1 after loosening the set screws easily possible and holding together of both tools during the countersinking process, because the cutting bevels of the drill fit into the grooves on the inner surface of the countersink.

Das auf den Bohrer aufgesetzte Senkwerkzeug ist nicht allein als Entgrater und Senker, sondern auch als Stufenbohrer verwendbar, wenn zusätzlich Spannnuten zur Abführung der Späne am Versenker angeordnet werden.The countersinking tool placed on the drill is not only used as a deburrer and countersinks, but can also be used as a step drill if additional flutes be arranged on the countersink to remove the chips.
