Description

Die Erfindung betrifft eine Zylinderanordnung gemäß des Patentanspruches 1.The invention relates to a cylinder arrangement according to the patent claim 1.

Eine derartige Zylinderanordnung ist in EP 1 653 088 B1 beschrieben. Bei dieser Zylinderanordnung sind Distanzscheiben einer Distanzscheibenanordnung vorgesehen, um das Einfahren der Kolbenstange relativ zum Zylindergehäuse zu begrenzen. Diese Distanzscheiben sind in eine Aufbewahrstellung und in eine Anschlagstellung verbringbar. In der Anschlagstellung umfassen die Distanzscheiben die Kolbenstange zumindest teilweise und liegen zumindest teilweise an der Kolbenstange an. Hierdurch kann es in nachteiliger Weise zu Beschädigungen, Zerkratzen sowie einem Verschleißen der Kolbenstange durch die sich in Anschlagposition befindlichen Distanzscheiben kommen.Such a cylinder arrangement is in EP 1 653 088 B1 described. In this cylinder arrangement spacers of a spacer assembly are provided to limit the retraction of the piston rod relative to the cylinder housing. These spacers can be brought into a storage position and in a stop position. In the stop position, the spacers comprise the piston rod at least partially and are at least partially against the piston rod. This can lead to damage, scratching and wear of the piston rod by the located in the stop position spacers disadvantageously.

Die DE 199 03 130 C1 offenbart eine Spannvorrichtung für ein Werkstück, mit einem stirnseitig an einer Betätigungseinrichtung angeordneten Lagerungskopf, an dem ein Spannarm schwenkbeweglich gelagert ist, wobei eine Betätigungsstange der Betätigungseinrichtung in den Lagerungskopf eintaucht und dort derart mit dem Spannarm in Wirkverbindung steht, dass dieser bei einer Vorwärtsbewegung der Betätigungsstange eine Schließbewegung und bei einer Rückwärtsbewegung der Betätigungsstange eine Öffnungsbewegung ausführt, und mit Mitteln zur variablen Vorgabe des Öffnungshubes des Spannarmes, die einen Anschlagkörper enthalten, der derart im Lagerungskopf positionierbar ist, dass ein mit der Betätigungsstange verbundener Gegenanschlag bei der Rückwärtsbewegung der Betätigungsstange auf ihn auflaufen kann.The DE 199 03 130 C1 discloses a clamping device for a workpiece, with a frontally arranged on an actuating device bearing head on which a clamping arm is pivotally mounted, wherein an actuating rod of the actuating device dips into the bearing head and there is in operative connection with the clamping arm, that this during a forward movement of the actuating rod a closing movement and with a backward movement of the actuating rod performs an opening movement, and with means for variably setting the opening stroke of the clamping arm containing a stop body, which is positionable in the bearing head so that a connected to the operating rod counter-stop during the backward movement of the actuating rod run up on him can.

Zu diesem Zweck sind unterschiedlich hohe Anschlagkörper vorhanden, die wahlweise eingesetzt werden, oder eine Installationsöffnung mit unterschiedlichen Bestückungsplätzen für je einen Anschlagkörper, oder unterschiedliche Installationsöffnungen zum Bestücken mit je einem Anschlagkörper.For this purpose, different height abutment bodies are present, which are used selectively, or an installation opening with different placement places for each stop body, or different installation openings for loading, each with a stop body.

Ferner ist ein Bewegungsspiel zwischen dem eingesetzten Anschlagkörper und der Betätigungsstange vorhanden, sodass die Bewegung der Betätigungsstange während des Übergangs zwischen der Offenstellung und der Schließstellung nicht behindert wird. Zudem kann der Anschlagkörper flexibel sein und die Betätigungsstange klammerartig hintergreifen, sodass eine Verliersicherung durch Aufclipsen des eingesetzten Anschlagkörpers gegeben ist.Furthermore, a movement play between the inserted stop body and the actuating rod is present, so that the movement of the actuating rod is not obstructed during the transition between the open position and the closed position. In addition, the stopper body can be flexible and engage the actuating rod like a clip, so that a captive is provided by clipping the inserted stop body.

Der Erfindung liegt die Aufgabe zu Grunde, in einfacher Weise sicherzustellen, dass die sich in Anschlagposition befindlichen Distanzscheiben die Kolbenstange nicht beschädigen.The invention is based on the object to ensure in a simple manner that located in the stop position spacers do not damage the piston rod.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Distanzscheibenanordnung eine Aufnahmevorrichtung zur Aufnahme der Distanzscheiben in ihrer Anschlagstellung aufweist, dass die in ihrer Anschlagstellung in der Aufnahmevorrichtung angeordneten Distanzscheiben einen radialen Abstand zur Kolbenstange aufweisen, und dass die Distanzscheibe durch Reibschluss in der Aufnahmevorrichtung gehalten werden.This object is achieved in that the spacer assembly has a receiving device for receiving the spacers in its stop position, that in its stop position in the receiving device arranged spacers have a radial distance from the piston rod, and that the spacer are held by frictional engagement in the receiving device.

Infolge dieser Maßnahme wird auf einfache Weise sichergestellt, dass die Distanzscheiben bei sich in Anschlagstellung befindlicher Position keinen Kontakt mit der Kolbenstange haben. Somit wird ein zerkratzen und verschleißen der Kolbenstange sicher vermieden.As a result of this measure it is ensured in a simple manner that the spacers have no contact with the piston rod in befindlichem in stop position position. Thus, a scratching and wear of the piston rod is reliably avoided.

Um die Distanzscheiben in einfacher Weise in ihrer Aufnahmevorrichtung in der zu der Kolbenstange beabstandeten Position sicher zu halten, ist vorgesehen, dass die Distanzscheiben eine größere Außenform als die Innenform der Aufnahmevorrichtung aufweisen, dass die Außenform der Distanzscheiben zur Anordnung in die Aufnahmevorrichtung verkleinerbar ist. Durch das Bestreben der Distanzscheiben, sich nach dem zusammendrücken und dem Verbringen in die Aufnahmevorrichtung, wieder auszudehnen, klemmen sich die Distanzscheiben in der Aufnahmevorrichtung fest und sind hier so sicher positioniert.In order to hold the spacers in a simple manner in their receiving device in the spaced-apart from the piston rod position, it is provided that the spacers have a larger outer shape than the inner shape of the receiving device, that the outer shape of the spacers Arrangement in the receiving device is reduced in size. By the efforts of the spacers to expand after squeezing and the introduction into the receiving device again, the spacers clamp firmly in the receiving device and are so securely positioned here.

Damit die Distanzscheiben sich in einfacher Weise in der Aufnahmevorrichtung verklemmen können und andererseits durch Zusammendrücken aus der Aufnahmevorrichtung herausgenommen werden können, ist vorgesehen, dass die Distanzscheiben aus einem elastisch verformbaren Material bestehen.Thus, the spacers can easily jam in the receiving device and on the other hand can be removed by squeezing out of the receiving device, it is provided that the spacers are made of an elastically deformable material.

Eine einfache Sicherung der Distanzscheiben in der Aufnahmevorrichtung lässt sich dadurch erreichen, dass die Distanzscheiben durch Reibschluss in der Aufnahmevorrichtung gehalten werden.A simple securing of the spacers in the receiving device can be achieved in that the spacers are held by frictional engagement in the receiving device.

Auch kann eine sichere Aufbewahrung der Distanzscheiben in der Aufnahmevorrichtung dadurch erreicht werden, dass die Distanzscheiben formschlüssig in der Aufnahmevorrichtung gehalten werden.Also, a safe storage of the spacers in the receiving device can be achieved in that the spacers are held in a form-fitting manner in the receiving device.

Um die Distanzscheiben in sinnvoller Weise in der Aufnahmevorrichtung positionieren zu können, ist vorgesehen, dass die Distanzscheiben eine an die Innenform der Aufnahmevorrichtung angepasste Außenkontur aufweisen.In order to position the spacers in a meaningful way in the receiving device, it is provided that the spacers have an adapted to the inner shape of the receiving device outer contour.

In einer Ausgestaltung ist vorgesehen, dass die Aufnahmevorrichtung an der Kolbenstange in deren freien Endbereich angeordnet ist.In one embodiment, it is provided that the receiving device is arranged on the piston rod in the free end region thereof.

In einer anderen Ausgestaltung ist vorgesehen, dass die Aufnahmevorrichtung an dem Zylindergehäuse des Zylinders angeordnet ist.In another embodiment, it is provided that the receiving device is arranged on the cylinder housing of the cylinder.

Um die Distanzscheiben auch bei Nichtverwendung vorteilhaft an der Maschine aufbewahren zu können, ist vorgesehen, dass im Bereich der Zylinderanordnung zumindest eine Aufbewahrvorrichtung für nicht im Bereich der Kolbenstange angeordnete Distanzscheiben vorgesehen ist.In order to be able to advantageously store the spacers on the machine even when not in use, it is provided that at least one storage device for spacers not arranged in the region of the piston rod is provided in the region of the cylinder arrangement.

Hierbei kann die zumindest eine Aufbewahrvorrichtung an der Kolbenstange in deren freien Endbereich oder an dem Zylindergehäuse des Zylinders angeordnet sein.In this case, the at least one storage device can be arranged on the piston rod in its free end region or on the cylinder housing of the cylinder.

Der hydraulische Zylinder 1 ist Bestandteil einer Zylinderanordnung. Diese Zylinderanordnung weist den Zylinder 1 mit dem Zylindergehäuse 2 und eine einfahrbare und ausfahrbare, aus den Zylindergehäuse 2 ragende Kolbenstange 3 auf. Die Kolbenstange 3 ist in dem Zylindergehäuse 2 in bekannter und daher nicht dargestellter Weise mit einem Kolben verbunden. An dem Zylindergehäuse 2 sind Hydraulikanschlüsse 4 in bekannter Weise angeordnet, um die Kolbenstange 3 gegenüber dem Zylindergehäuse 2 ein- und ausfahren zu können. Die Hydraulikanschlüsse 4 sind über nicht dargestellte Hydraulikleitungen mit einer ebenfalls nicht dargestellten Hydraulikanlage bekannter Weise verbunden.The hydraulic cylinder 1 is part of a cylinder arrangement. This cylinder arrangement has the cylinder 1 with the cylinder housing 2 and a retractable and extendable, protruding from the cylinder housing 2 piston rod 3. The piston rod 3 is connected in the cylinder housing 2 in a known and therefore not shown manner with a piston. On the cylinder housing 2 hydraulic connections 4 are arranged in a known manner to the piston rod 3 relative to the cylinder housing 2 to extend and retract. The hydraulic connections 4 are connected via hydraulic lines, not shown, with a hydraulic system, also not shown, known manner.

Um das Einfahren der Kolbenstange 3 zur Einstellung von Werkzeugen oder für andere Funktionen, ist eine Distanzscheibenanordnung 5 den Zylinder 1 zugeordnet. Diese Distanzscheibenanordnung 5 weist Distanzscheiben 6 auf. Je nachdem wie weit die Kolbenstange 3 zur Einstellung von Werkzeugen oder für andere Funktionen eingefahren werden soll bzw. muss wird eine entsprechende Anzahl von Distanzscheiben 6 im Bereich der Kolbenstange 3 platziert. Hierzu weist die Distanzscheibenanordnung 5 eine Aufnahmevorrichtung 7 zur Aufnahme der Distanzscheiben 6 in ihrer Anschlagstellung auf. Diese Aufnahmevorrichtung 7 ist im Bereich der Kolbenstange 3 angeordnet. Im Ausführungsbeispiel ist die Aufnahmevorrichtung 7 an dem freien Endbereich 8 der Kolbenstange 3 für die Aufnahme der Distanzscheiben 6 in ihrer Anschlagstellung an dem Zylindergehäuse 2 angeordnet. Es ist auch möglich, eine Aufnahmevorrichtung für die nicht in Anschlagstellung befindlichen Distanzscheiben 6 in nicht dargestellter Weise an Zylindergehäuse 2 anzuordnen.In order to retract the piston rod 3 for adjusting tools or for other functions, a spacer assembly 5 is assigned to the cylinder 1. This spacer assembly 5 has spacers 6. Depending on how far the piston rod 3 is to be retracted for setting tools or for other functions or must a corresponding number of spacers 6 in the region of the piston rod 3 is placed. For this has the spacer assembly 5, a receiving device 7 for receiving the spacers 6 in its stop position. This receiving device 7 is arranged in the region of the piston rod 3. In the exemplary embodiment, the receiving device 7 is arranged on the free end region 8 of the piston rod 3 for receiving the spacers 6 in its stop position on the cylinder housing 2. It is also possible to arrange a receiving device for the not in stop position located spacers 6 in a manner not shown to the cylinder housing 2.

Die Distanzscheiben 6 weisen durch eine Aussparung eine Innenform auf, die an die Kolbenstange 3 angepasst ist. Diese Aufnahmevorrichtung 7 weist eine Innenform auf, die an die Außenkontur der Distanzscheiben 6 angepasst ist. Somit weisen die Distanzscheiben 6 eine an die Innenform der Aufnahmevorrichtung 7 angepasste Außenkontur auf. Die in ihrer Anschlagstellung in der Aufnahmevorrichtung 7 angeordneten Distanzscheiben 6 weisen einen radialen Abstand zur Kolbenstange 3 auf, so dass hier ein Freiraum 9 entsteht. Durch diese Anordnung befinden sich die Distanzscheiben 6 in ihrer Anschlagstellung immer in ausreichender Weise beabstandet zu der Kolbenstange 3. Hierdurch werden Beschädigungen, wie ein Zerkratzen oder Verschleißen der Kolbenstange 3 durch die Distanzscheiben 6 vermieden.The spacers 6 have a recess on an inner shape, which is adapted to the piston rod 3. This receiving device 7 has an inner shape which is adapted to the outer contour of the spacers 6. Thus, the spacers 6 have an adapted to the inner shape of the receiving device 7 outer contour. The arranged in its stop position in the receiving device 7 spacers 6 have a radial distance from the piston rod 3, so that here a free space 9 is formed. By this arrangement, the spacers 6 are always sufficiently spaced in its stop position to the piston rod 3. As a result, damage, such as scratching or wear of the piston rod 3 are avoided by the spacers 6.

Die Distanzscheiben 6 weisen eine größere Außenform als die Innenform der Aufnahmevorrichtung 7 auf. Um die Distanzscheiben 6 in der Aufnahmevorrichtung 7 anordnen zu können, ist die Außenform der Distanzscheiben 6 zur Anordnung in die Aufnahmevorrichtung 7 zu verkleinern. Dieses Verkleinern geschieht durch Zusammendrücken der Distanzscheiben 6, die aus einem elastisch verformbaren Material bestehen. In Fig.3 ist mit durchzogen Linien die Form der Distanzscheibe 6 in etwas zusammengedrückter Form bei Anordnung in der Aufnahmevorrichtung 7 und mit gestrichelten Linien die entsprechende entspannte Form der aus einem elektrischen Material bestehende Distanzscheiben 6 dargestellt. Nach dem Einsetzen der Distanzscheiben 6 in die Aufnahmevorrichtung 7 wollen sich die zusammen gedrückten Distanzscheiben 6 wieder auszudehnen und legen sich mit ihren Außenseiten an den Innenbereich der Aufnahmevorrichtung 7 an. Hierdurch Verklemmen sich die Distanzscheiben 6 in der Aufnahmevorrichtung 7, dass sie durch Reibschluss in der Aufnahmevorrichtung 7 gehalten werden. Zusätzlich kann in nicht dargestellter Weise, um die formschlüssig in der Aufnahmevorrichtung 7 angeordneten Distanzscheiben 6 zusätzlich zu sichern, noch eine mechanische, nicht dargestellte Sicherungsvorrichtung vorhanden sein.The spacers 6 have a larger outer shape than the inner shape of the receiving device 7. In order to arrange the spacers 6 in the receiving device 7, the outer shape of the spacers 6 for arrangement in the receiving device 7 is to be reduced. This reduction is done by squeezing the spacers 6, which consist of an elastically deformable material. In Figure 3 is shown with solid lines the shape of the spacer 6 in somewhat compressed form when placed in the receiving device 7 and with dashed lines the corresponding relaxed shape of existing of an electrical material shims 6. After inserting the spacers 6 in the receiving device 7, the pressed together spacers 6 want to expand again and lie with their outer sides against the inner region of the receiving device 7. As a result, the spacers 6 get jammed in the receiving device 7, that they are held by frictional engagement in the receiving device 7. In addition, in a manner not shown, in order to additionally secure the form-fitting arranged in the receiving device 7 shims 6, still a mechanical, not shown securing device may be present.

Wie erwähnt, werden die Distanzscheiben 6 in der erforderlichen Anzahl, je nachdem wie der Einfahrweg der Kolbenstange 3 begrenzt werden muss, auf die Kolbenstange 3 und in die Aufnahmevorrichtung 7 eingesetzt. Hierbei bilden die Distanzscheiben 6 einen mechanischen Anschlag. Somit hängt die Anschlagposition von der Anzahl in Anschlagstellung gebrachten Distanzscheiben 6 ab. Dieser Anschlag ist zwischen dem Zylindergehäuse 2 und den mit der Kolbenstange 3 verbundenen Anschlagelementen und der zugeordneten Distanzscheibenanordnung 5 sowie der Aufnahmevorrichtung 7 ausgebildet.As mentioned, the spacers 6 in the required number, depending on how the Einfahrweg the piston rod 3 must be limited, used on the piston rod 3 and in the receiving device 7. Here, the spacers 6 form a mechanical stop. Thus, the stop position depends on the number placed in the stop position shims 6. This stop is formed between the cylinder housing 2 and connected to the piston rod 3 stop elements and the associated spacer assembly 5 and the receiving device 7.

Die Distanzscheiben 6 bilden also in der Anschlagstellung, d.h., wenn sie im Bereich der Kolbenstange 3 angeordnet sind, einen mechanischen Anschlag und begrenzen so das Einfahren der Kolbenstange 3 relativ zum Zylindergehäuse 2.The spacers 6 thus form a mechanical stop in the stop position, that is, when they are arranged in the region of the piston rod 3, and thus limit the retraction of the piston rod 3 relative to the cylinder housing 2.

Für nicht im Bereich der Kolbenstange 3 angeordnete Distanzscheiben 6 ist im Bereich der Zylinderanordnung eine Aufbewahrvorrichtung 9 vorgesehen. Diese Aufbewahrvorrichtung 9 ist im Ausführungsbeispiel am Rahmen zählen der Maschine angeordnet. Grundsätzlich kann diese Aufbewahrvorrichtung 9 an jeder Stelle einer Maschine, so auch an der Kolbenstange 3 in deren freien Endbereich 8 oder an dem Zylindergehäuse 2 des Zylinders 1 angeordnet sein.For not arranged in the region of the piston rod 3 spacers 6, a storage device 9 is provided in the region of the cylinder assembly. This storage device 9 is arranged in the embodiment of the frame counting the machine. In principle, this storage device 9 can be arranged at any point of a machine, so also on the piston rod 3 in the free end region 8 or on the cylinder housing 2 of the cylinder 1.
