Description

Die Erfindung betrifft eine Spannvorrichtung für 1nnen- und Außenspannung, welche sich durch einfache wirtschaftliche Herstellung anfertigen läßt und doch einen genauen kundlauf gewährleistet.The invention relates to a clamping device for internal and external clamping, which can be made by simple economical production and yet an accurate customer run guaranteed.

Bekannte Spannvorrichtungen mit kegelförmik(sen Ringspannscheiben, welche mit Feder-3 schlitzen versehen sind, sind teuer in der Herstellung, haben eine kleine Spannausdehnung und zerspringen leicht.Known clamping devices with conical shape (sen ring clamping disks, which are provided with spring-3 slots are expensive to manufacture a small stretch and easily shatter.

Ferner sind geschlossene kegelförmige Ringe bekannt, welche ineinanderdrücken und durch #die Elastizität des Werkstoffes eine Spannung gewährleisten. Diese Spannelemente sind teuer in der Herstellung und haben nur eine ganz geringe Dehnung.Furthermore, closed, conical rings are known which press into one another and ensure tension through the elasticity of the material. These clamping elements are expensive to manufacture and have very little elongation.

Durch die vorgeschlagene Form der Spannringe wird gegenüber Odem Bekannten bei einfacherer Herstellung eine größere Spanndehnung erreicht. Der Gegenstand der Erfindung ist an einem Ausführungsbeispiel in der Zeichnung erläutert.The proposed shape of the clamping rings is compared to Odem acquaintances a greater elongation is achieved with simpler manufacture. The subject of The invention is explained using an exemplary embodiment in the drawing.

Auf dem Spanndorn i sitzen zwischen den Zentrierringen 2 und 5 die geöffneten Innenspannringe 3 und die geöffneten Außenspannringe 4- mit kreisförmigem Querschnitt. Die Innen- und Außenspannringe 3 und 4 in Verbindung mit den Zentrierringen 2 und 5 ergeben die Grundelemente der Erfindung. Durch Anziehen der Spannmutter 7 überträgt sich der Axialdruck über den Zwischenring 6 und den Zentrierring 5 auf Innen- und Außenspannringe 3 und 4. Die Ringe werden somit ineinandergeschoben. ' Der Innenring wird kleiner und preßt sich auf den Spanlidorn i. Der Außenring wird größer und preßt sieh gegen das Werkstück 8. Die Zahl der Innen- und Außenspannringe richten sich nach der jeweiligen Länge des zu spannenden Teiles. Durch das Anpresseil der Spannringe wird eine kraftschlüssige Verbindung zwischen dem Spanndorn i und dem Werkstück 8 hergestellt. Eine Umdrehung der Spannmutter 7 genügt, um das Werkstück zu spannen und zu lockern. Die geöffneten Federspannringe 3 und 4, welche sich durch einen geringen Druck ineinanderschieben, ha;ben lediglich die Aufgabe, das zu spannende Teil festzuklemmen. Sie können,deshalb ganz einfache, aus Federstahldraht gerollte und aufgesägte Ringe ohne weitere Bearbeitung sein. Die Zentrierringe 2, und 5 haben die Aufgabe, den genauen Rundlauf des zu spannenden Teiles zu gewährleisten. Durch Wechseln der Zentrier- und Spannringe lassen sich mehrere Durchmesserdimensionen auf einem Aufnahmedorn spannen.On the mandrel i sit between the centering rings 2 and 5, the open internal clamping rings 3 and the open external clamping rings 4- with a circular cross-section. The inner and outer clamping rings 3 and 4 in connection with the centering rings 2 and 5 result in the basic elements of the invention. By tightening the clamping nut 7 , the axial pressure is transmitted via the intermediate ring 6 and the centering ring 5 to the inner and outer clamping rings 3 and 4. The rings are thus pushed into one another. '' The inner ring becomes smaller and presses itself on the Spanlidorn i. The outer ring becomes larger and presses against the workpiece 8. The number of inner and outer clamping rings depends on the length of the part to be clamped. A non-positive connection between the mandrel i and the workpiece 8 is established by the pressing part of the clamping rings. One turn of the clamping nut 7 is sufficient to clamp and loosen the workpiece. The open spring clamping rings 3 and 4, which slide into one another under low pressure, only have the task of clamping the part to be clamped. They can therefore be very simple rings made of spring steel wire rolled and sawn open without further processing. The centering rings 2 and 5 have the task of ensuring the exact concentricity of the part to be clamped. By changing the centering and clamping rings, several diameter dimensions can be clamped on one arbor.
