Abstract

The invention relates to a cylinder assembly, comprising a cylinder (1), which has a cylinder housing (2) and a retractable and extendable piston rod (3) that protrudes from the cylinder housing, and a spacing-plate assembly (5), which has spacing plates (6) that can be brought into a storage position and into a stop position, wherein, in the stop position, the spacing plates form a mechanical stop and limit the retraction of the piston rod in relation to the cylinder housing in order to define a stop position for the piston rod, wherein the stop position depends on the number of spacing plates brought into the stop position, wherein the spacing plates have a shape matched to the piston rod and are arranged at least partially surrounding the piston rod in the stop position, wherein the stop is formed between the cylinder housing and the stop element, which is connected to the piston rod, and the associated spacing-plate assembly. In order to ensure in a simple manner that, when the spacing plates are in the stop position, the spacing plates do not damage the piston rod, the spacing-plate assembly, according to the invention, has an accommodating device (7) for accommodating the spacing plates in the stop position of the spacing plates and, when the spacing plates are arranged in the stop position of the spacing plates in the accommodating device, the spacing plates have a radial distance from the piston rod.

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 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
Hydraulikanschlüsse 4 sind über nicht dargestellte Hydraulikleitungen mit einer ebenfalls nicht dargestellten Hydraulikanlage bekannter Weise verbunden.  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 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.

Thus, the spacers 6 have an adapted to the inner shape of the receiving device 7 outer contour. The in their stop position in the
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. Receiving device 7 arranged spacers 6 have a radial distance from the piston rod 3, so that here a clearance 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 The spacers 6 have a larger outer shape than the inner shape of the receiving device 7. To the spacers 6 in the

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 Shims 6 shown. 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, to the form-fitting arranged in the receiving device 7
Distanzscheiben 6 zusätzlich zu sichern, noch eine mechanische, nicht dargestellte Sicherungsvorrichtung vorhanden sein. To secure spacers 6 in addition, nor 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 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 hangs
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  Stop position of the number placed in the stop position spacers 6 from. This stop is between the cylinder housing 2 and connected to the piston rod 3 stop elements and the associated
Distanzscheibenanordnung 5 sowie der Aufnahmevorrichtung 7 ausgebildet. Shim assembly 5 and the receiving device 7 is formed.
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. 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. The spacers 6 thus form in the stop position, ie, if they are arranged in the region of the piston rod 3, a mechanical stop and limit the retraction of the piston rod 3 relative to the cylinder housing 2. For not arranged in the region of the piston rod 3 shims 6 is in the area the cylinder assembly a storage device 9 is provided. 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.
