Description

Futterbacken mit Selbstspannkolben zum Spannen von Werkstücken, Die Erfindung betrifft eine Butterbacke mit Selbstspannkolben zum Spannen von Werkstticken. Chuck jaws with self-clamping piston for clamping workpieces, Die The invention relates to a butter cheek with self-tensioning piston for tensioning workpieces.

Bekanntlich wird in Drehbackenfuttern das Werkstück durch drei um 1200 zueinander versetzte Backen festgehalten.As is well known, the workpiece is rotated by three in rotary jaw chucks 1200 staggered jaws held.

Beim Festspannen des Werkstückes besteht jedoch die Neigung, den Klemmstift der Backe hinauszuschlebenç Der Erfindung liegt die Aufgabe zugrunde, eine Putterbacke der eingangs genannten Art zu schaffen, welche das Werkstück beim radialen Spannen gleichzeitig in Axialrichtung gegen die Auflagestifte zu drücken ermögtcht.When clamping the workpiece, however, there is a tendency to the clamping pin The invention is based on the object of a putter cheek of the type mentioned to create, which the workpiece during radial clamping at the same time allows to press in the axial direction against the support pins.

Die Lösung dieser Aufgabe ist darin zu sehen, dass der Spannkolben Jeder Futterbacke auf einer elastischen Zwischenlage aufliegt, Die Erfindung ist im folgenden an Sand schematischer Zeichnungen an einem Ausführungabeispiel ergänzend be schrieben.The solution to this problem can be seen in the fact that the tensioning piston Each chuck jaw rests on an elastic intermediate layer, the The invention is shown below in the form of schematic drawings using an exemplary embodiment additionally described.

Figur l ist ein Vertikalsohnitt durch eine Butterbacke nach der Erfindung. Figure 1 is a vertical dish through a butter cheek according to the invention.

Figur 2 ist eine Prinzipdarstellung, die das Kräfte parallelograme während des Festklemmens der Futter backe zeigt, Die in den Figuren dargestellte Futterbacke umfasst einen Spannkolben 1 der auf einer elastischen Zwischenlage 2 aus Gummi oder dergleichen aufliegt und durch eine in eine elastische Büchse 4 eingesteckte Schraube 3 festgehalten wird. Figure 2 is a schematic diagram showing the forces parallelograme shows during the clamping of the chuck jaw, The one shown in the figures The chuck jaw comprises a clamping piston 1 which is supported on an elastic intermediate layer 2 made of rubber or the like and inserted into an elastic sleeve 4 by a Screw 3 is held.

Man erkennt aus Figur 2 dass die radiale Kraft P sich zerlegen lässt in eine normal zu der schiefen Berührungsebene zwischen Spannkoiben und Futterbacke gerichtete Kraft und eine axiale Komponente, die das Werkstück gegen die Auflagestifte drückt.It can be seen from FIG. 2 that the radial force P can be decomposed in a normal to the inclined plane of contact between the clamping collet and the chuck jaw directional force and an axial component that pushes the workpiece against the support pins presses.
