Definitions
- the present invention relates to attachment clamping jaws for a clamping device for clamping workpieces according to claim 1.
- clamping devices In the CNC machining of workpieces often clamping devices must be used, with which a variety of possible shapes and sizes of workpieces can be clamped and machined.
- the requirements of such clamping devices are therefore such that they should on the one hand provide the best possible accessibility for the processing tools, but on the other hand also guarantee a very stable and secure clamping.

Abstract
Description
Die vorliegende Erfindung betrifft Aufsatzspannbacken für eine Spannvorrichtung zum Einspannen von Werkstücken nach Patentanspruch 1.The present invention relates to attachment clamping jaws for a clamping device for clamping workpieces according to claim 1.
In der CNC-Bearbeitung von Werkstücken müssen oft Spanneinrichtungen eingesetzt werden, mit denen eine Vielzahl an möglichen Formen und Grössen von Werkstücken einspann- und bearbeitbar sind. Die Anforderungen an solche Spanneinrichtungen sind deshalb derart, dass sie einerseits eine möglichst gute Zugänglichkeit für die Bearbeitungswerkzeuge gewähren sollen, andererseits aber auch eine sehr stabile und sichere Einspannung garantieren müssen. Diese beiden Forderungen stehen oft in einem gewissen Widerspruch, weil nur wenig Spannfläche für die Einspannung des zu bearbeitenden Werkstückes zur Verfügung steht, die Haltekräfte aber gross sein müssen und bleibende Verformungen, verursacht durch die Spanneinrichtung selber, nach Möglichkeit vermieden werden sollen.In the CNC machining of workpieces often clamping devices must be used, with which a variety of possible shapes and sizes of workpieces can be clamped and machined. The requirements of such clamping devices are therefore such that they should on the one hand provide the best possible accessibility for the processing tools, but on the other hand also guarantee a very stable and secure clamping. These two requirements are often in a certain contradiction, because only a small clamping surface for the clamping of the workpiece to be machined is available, but the holding forces must be large and permanent deformations caused by the clamping device itself, if possible to be avoided.
Um eine möglichst grosse Vielfalt an Werkstücken bearbeiten zu können, werden deshalb oft Spanneinrichtungen mit auswechselbaren Aufsatzspannbacken eingesetzt. Ein Beispiel für derartige Spanneinrichtungen sind die Zentrumsspanner der Firma Hemo Werkzeugbau, ersichtlich aus dem Verkaufsprospekt ZS/d3/4000/06/06 der Hemo Werkzeugbau. Die auswechselbaren Aufsatzspannbacken ermöglichen die Anpassung an verschiedene Werkstücke und Werkstückgrössen, beispielsweise mittels verschiedener Backenhöhen, Backenhärten, Backenriffelungen etc.To be able to process the largest possible variety of workpieces, therefore, clamping devices are often used with interchangeable essay jaws. An example of such tensioning devices are the center tensioners from Hemo Werkzeugbau, which can be seen from the sales prospectus ZS / d3 / 4000/06/06 of Hemo Werkzeugbau. The replaceable top jaws allow adaptation to different workpieces and workpiece sizes, for example by means of different jaw heights, baking hardnesses, jaw corrugations etc.
Eine weitere Möglichkeit zum sicheren und möglichst platzsparenden Einspannen von Werkstücken ist in der
Es ist deshalb die Aufgabe der Erfindung, eine verbesserte Lösung vorzuschlagen.It is therefore the object of the invention to propose an improved solution.
Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.The object is solved by the features of patent claim 1.
Die Lösung besteht darin, dass die Spannwirkung der Spannbacken einer Spannvorrichtung mit einer im Nahbereich der Spannflächen wirksam werdenden Spannschraube nach dem Einspannen des zu bearbeitenden Werkstückes in der Spannvorrichtung noch verstärkt wird.The solution is that the clamping action of the clamping jaws of a clamping device with an effective in the vicinity of the clamping surfaces clamping screw is tightened after clamping the workpiece to be machined in the clamping device.
Ausgangspunkt ist dabei die Überlegung, dass bei gängigen Spannvorrichtungen die Spannachse, über die die Spannkraft übertragen wird, doch relativ weit entfernt von den Spannflächen liegt, zwischen denen das Werkstück tatsächlich eingespannt und gehalten ist. Somit können selbst relativ hohe Kräfte in der Spannachse am Zielort, nämlich zwischen den Spannflächen, nur noch teilweise wirksam werden.The starting point is the consideration that with common clamping devices, the clamping axis, via which the clamping force is transmitted, but relatively far away from the clamping surfaces, between which the workpiece is actually clamped and held. Thus, even relatively high forces in the clamping axis at the destination, namely between the clamping surfaces, only partially effective.
Dieser Lösungsansatz wird zwar bereits in einer früheren Patentanmeldung Nr.
Mittels einer einfachen Spannschraube, die wegen der guten Zugänglichkeit der Aufsatzspannbacken auch nach dem Einspannen des Werkstückes noch mit Leichtigkeit einsetz- und spannbar ist, können die wirksamen Spannkräfte und damit die Festigkeit und Stabilität des Spannsitzes wesentlich erhöht werden.By means of a simple clamping screw, which is still easy to insert and tension because of the good accessibility of essay jaws even after clamping the workpiece, the effective clamping forces and thus the strength and stability of the clamping seat can be significantly increased.
Weitere Verbesserungen sind möglich, wenn die Spannflächen der Aufsatzspannbacken noch zusätzlich mit "Mikrozähnen" versehen werden, um neben dem Kraftschluss auch noch einen Formschluss für die Einspannung zu erzielen. Wegen der Kleinheit dieser Mikrozähne bleiben die Eindruckmarken gering und sind deshalb oft auch nicht störend.Further improvements are possible if the clamping surfaces of the top clamping jaws are additionally provided with "micro-teeth" in order to achieve not only the frictional connection but also a form fit for the clamping. Because of the small size of these micro teeth impression marks remain low and are therefore often not disturbing.

Die erste Aufsatzspannbacke 2a hat angrenzend an die Werkstückauflage 7 ein erstes Loch 10a zur Aufnahme einer Spannschraube 11. Die zweite Aufsatzspannbacke 2b hat angrenzend an die Werkstückauflage 7 ein zweites Loch 10b zur Aufnahme der Spannschraube 11. Die erste Aufsatzspannbacke 2a ist mit der zweiten Aufsatzspannbacke 2b über das erste und das zweite Loch 10a,10b in Spannrichtung S mit der Spannschraube 11 verbindbar. Mittels der Spannschraube 11 ist somit die erste Aufsatzspannbacke 2a mit der zweiten Aufsatzspannbacke zusätzlich verspannbar. Zusätzlich verspannbar heisst, dass neben der Spannwirkung, die durch den Spanntrieb 4 aufgebracht wird, über die Spannschraube 11 eine weitere, im Nahbereich der Einspannung wirksam werdende Spannkraft aufgebracht werden kann. Der Begriff "angrenzend" ist somit in diesem Sinne zu verstehen.The first attachment jaw 2a has adjacent to the workpiece support 7 a
Für die Spannschraube 11 wie auch für die Löcher 10a,10b sind verschiedene Ausführungen möglich. So ist es möglich, dass die Spannschraube (wie gezeigt) eine gewöhnliche Innensechskantschraube ist, während das erste Loch 10a ein passendes Innengewinde aufweist und das zweite Loch 10b lediglich ein Durchgangsloch ist.For the
