Description

Drehspitze Drehspitzen mit selbsttätiger, durch das eingespannte Werkstück ausgelöster Schmierung sind in der Art bekannt, daß in der Mittelachse der Spitze in einem Kanal ein Ventil angeordnet ist, dessen Schaft als Nadel ausgebildet aus der Spitze hervorragt. Bekannt sind auch Drehspitzen, bei denen ein gewöhnlicher Schmierkanal außerhalb der Mittelachse auf der Lauffläche des Körners mündet.Turning center Turning centers with automatic, through the clamped workpiece triggered lubrication are known in the manner that in the central axis of the tip a valve is arranged in a channel, the shaft of which is designed as a needle the tip protrudes. Rotary tips are also known where an ordinary one Lubrication channel opens outside the central axis on the running surface of the center.

Das Neue der Erfindung besteht drin, daß die als Ventil ausgebildete, die Schmierung auslösende Nadel nicht in der lMtte der Spitze, sondern exzentrisch angeordnet ist. Die der Größe der Spitze angemessene Exzentrizität bewirkt, daß die Spitze der Nadel nicht in den Hohlraum der Zentrierbohrung trifft, sondern auf die Anlagefläche des Werkstückes.The novelty of the invention is that the valve designed as a, The needle that triggers lubrication is not in the center of the tip, but eccentrically is arranged. The eccentricity appropriate to the size of the tip causes the tip of the needle does not hit the cavity of the centering hole, but instead the contact surface of the workpiece.

Die Zeichnung zeigt ein Ausführungsbeispiel. In der Einsatzspitze a ist die Ventilnadel ö im allgemeinen auf der entlasteten Seite angeordnet. Die Ventilnadel sitzt so weit exzentrisch, daß die Spitze c auf die Anlagefläche d des Werkstückes trifft.The drawing shows an embodiment. At the top a, the valve needle ö is generally arranged on the relieved side. the Valve needle is so far eccentric that the tip c on the contact surface d of the Workpiece.

Der durch die Erfindung gegenüber dem Bekannten erzielte Fortschritt besteht darin, daß die Spitze c der Nadel auch im Ruhezustand nur wenig aus dem Kanal herausragt. Bei den bisher bekannten Drehspitzen ragte die Nadel nicht nur um den Ventilhub, sondern auch um die ganze Tiefe der .Zerrtrierbohrung hervor. Da die Tiefe der Zentrierbohrungen aber stark variiert, ergeben sich hieraus Schwierigkeiten dadurch, daß die Nadel zu kurz oder zu lang ist. Auch wurde die hervorstehende Nadelspitze leicht abgebrochen. Die erfindungsgemäße Nadel dagegen kann ganz genau abgehängt werden, da ja die Anlagefläche des Werkstückes unmittelbar die Spitze berührt. Durch die Erkenntnis von der Bedeutung dieses Umstandes wurde das praktisch brauchbare Präzisionswerkzeug geschaffen.The progress achieved by the invention over the known is that the tip c of the needle only slightly out of the at rest Canal sticks out. In the previously known rotary tips, the needle not only protruded around the valve lift, but also around the entire depth of the .Zerrtrierbohrung. However, since the depth of the centering bores varies greatly, difficulties arise from this in that the needle is too short or too long. Also became the protruding needle point easily broken off. The needle according to the invention, on the other hand, can be removed very precisely because the contact surface of the workpiece is in direct contact with the tip. By the realization of the importance of this circumstance became that which was practically useful Precision tool created.
