Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 eine Seitenansicht eines Arbeitszylinders, teilweise im Schnitt, Figur 2 eine Draufsicht auf den Arbeitszylinder, Figur 3 einen Schnitt längs III-III nach Figur 2.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a side view of a working cylinder, partly in section, FIG. 2 shows a top view of the working cylinder, FIG. 3 shows a section along III-III according to FIG. 2.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In den Figuren ist mit 10 ein Zylinderrohr bezeichnet, das beidseitig durch Deckel 11, 12 verschlossen ist und über welche das Zylinderrohr mit Hilfe von vier Spannschrauben 13 mit den Deckeln festgespannt wird. In den Deckeln 11 und 12 ist jeweils eine Öffnung 14, 15 für das Zuführen bzw. Abführen des Druckmittels zum Betätigen des Kolbens bzw. der Kolbenstange ausgebildet.In the figures, 10 denotes a cylinder tube which is closed on both sides by covers 11, 12 and via which the cylinder tube is clamped to the covers with the aid of four clamping screws 13. In the covers 11 and 12, an opening 14, 15 is formed for the supply or discharge of the pressure medium for actuating the piston or the piston rod.

Seitlich und parallel zum Zylinderrohr 1C verlaufend sind im Deckel 12 zwei durchgehende Bohrungen 16, 17 ausgebildet, in welchen Stangen 18, 16 gleitend geführt sind, die an ihrem dem Deckel 11 abgewandten Ende durch ein Joch 19 verbunden sind. Die Stange 18 ist kodiert, z. B. dadurch, daß in bestimmten Abständen Ringe 20 aus einem Werkstoff mit magnetischen Eigenschaften eingelegt sind, die sich wesentlich von den magnetischen Eigenschaften des Werkstoffs der Stange 18 unterscheiden. Es können aber auch gewindeartige Rillen vorgesehen sein, die mit einem ähnlichen Material gefüllt sind oder es kann auch ein Band aus magnetisiertem Werkstoff in die Stange 18 eingelassen sein.Running laterally and parallel to the cylinder tube 1C, two through bores 16, 17 are formed in the cover 12, in which rods 18, 16 are slidably guided, which are connected at their end facing away from the cover 11 by a yoke 19. The rod 18 is coded, e.g. B. in that at certain intervals rings 20 made of a material with magnetic Properties are inserted that differ significantly from the magnetic properties of the material of the rod 18. However, thread-like grooves can also be provided, which are filled with a similar material, or a band of magnetized material can also be inserted into the rod 18.

Zum Abtasten der Position der Stange 18 und damit auch der Kolbenstange dient ein Sensor 21, der Teil einer auf dem Deckel 12 angeordneten Elektronik 22 ist. Mit Hilfe dieser Elektronik wird ein Steuerventil 23 betätigt, das .über der Elektronik und auf dem Deckel sitzt und das zur Steuerung einer Bremseinrichtung 24 dient, die ebenfalls am Deckel 12 angeordnet ist.A sensor 21, which is part of electronics 22 arranged on the cover 12, is used to sense the position of the rod 18 and thus also the piston rod. With the aid of this electronics, a control valve 23 is actuated, which sits above the electronics and on the cover and which serves to control a braking device 24 which is also arranged on the cover 12.

Die Kolbenstange ist mit 25 bezeichnet. Auf ihr ist gleitend drehbar ein Exzenterring 26 gelagert, der gleichzeitig auch in einer Bohrung 27 des Deckels gelagert ist. Der Exzenter 26 hat einen nach obenstehenden Bolzen, der in einen Schlitz 29 eines Kolbens 30 greift, der in einer Bohrung 31 der Bremseinrichtung gleitend geführt ist. Der Kolben 30 wird über eine Bohrung 32 und eine nicht dargestellte Leitung vom Ventil 23 her mit Druckmittel beaufschlagt. Entgegen der Druckmitteldruckkraft wirkt auf den Kolben 30 eine Druckfeder 34, die sich an einem Federwiderlager 35 abstützt, das in einem Seitenteil 36 der Bremseinrichtung untergebracht ist. Eine derartige Bremseinrichtung ist bekannt aus der DE-OS 25 15 566.2.The piston rod is designated 25. An eccentric ring 26 is slidably rotatably mounted on it, which is also mounted in a bore 27 of the cover. The eccentric 26 has an upstanding bolt which engages in a slot 29 of a piston 30 which is slidably guided in a bore 31 of the braking device. The piston 30 is acted upon by a valve 32 through a bore 32 and a line, not shown, with pressure medium. Contrary to the pressure medium pressure force acts on the piston 30 a compression spring 34 which is supported on a spring abutment 35 which is housed in a side part 36 of the braking device. Such a braking device is known from DE-OS 25 15 566.2.

Wenn kein Druck in der Bohrung 31 ansteht, bringt die Druckfeder 34 den Kolben 30 in eine solche Position, daß der Bolzen 28 den Exzenter 26 so verdreht, daß er die Kolbenstange 25 festspannt.If there is no pressure in the bore 31, the compression spring 34 brings the piston 30 into such a position that the bolt 28 rotates the eccentric 26 so that it clamps the piston rod 25.

Soll die Kolbenstange 25 in eine bestimmte Position fahren, so wird von der Elektronik das Ventil 23 derart angesteuert, daß Druckmittel über die Bohrung 32 in die Bohrung 31 strcmt. Dadurch bewegt sich der Kolben 30 nach links, der Bolzen 28 wird entgegen dem Uhrzeigersinn derart verschwenkt, daß der Exzenterring 26 die Kolbenstange freigibt. Durch Beaufschlagung des Kolbens im Zylinderrohr verfährt nun der Kolben samt Kolbenstange. Hat diese eine bestimmte Position erreicht, die durch die Kodierung auf der Stange 18 gekennzeichnet ist, so gibt die Elektronik 22 ein Signal an das Ventil 23, das nun sofort den Druckmittelzufluß zur Bohrung 32 stoppt. Jetzt bringt die Druckfeder 34 die Bremseinrichtung wieder in Bremsstellung, die Kolbenstange wird sofort festgespannt. Durch entsprechende Kodierung und Ansteuerung über die Elektronik kann die Kolbenstange in jede beliebige Stellung gefahren und dort festgespannt werden.If the piston rod 25 is to move into a certain position, the electronics control the valve 23 in such a way that pressure medium flows through the bore 32 into the bore 31. As a result, the piston 30 moves to the left, the bolt 28 is pivoted counterclockwise in such a way that the eccentric ring 26 releases the piston rod. By acting on the piston in the cylinder barrel, the piston and piston rod now move. If this has reached a certain position, which is characterized by the coding on the rod 18, the electronics 22 give a signal to the valve 23, which now immediately stops the pressure medium flow to the bore 32. Now the compression spring 34 brings the braking device back into the braking position, the piston rod is immediately tightened. The piston rod can be moved to any position and clamped there by means of appropriate coding and control via the electronics.

Damit durch die auf die Kolbenstange 25 wirkende exzentrische Bewegung keine Verdrehung der Kolbenstange möglich ist, ist zwischen dem Joch 19 und der Kolbenstange 25 eine Ausgleichskupplung 39 vorgesehen. Diese besteht im wesentlichen aus einem zylindrischen Körper 40, der auf die Kolbenstange 25 mittels eines an ihrem Ende angeordneten Schraubenbolzen 41 und einer Mutter 42 aufgeschraubt ist. Der zylindrische Körper 40 weist einen Querschlitz 45 auf, in den eine Scheibe 43 eingesetzt ist mit einem zum Joch hin sich erstreckenden Bolzen 44, der mit dem Joch mittels einer in dieser angeordneten Schraube 46 verschraubt ist. Der zylindrische Körper 40 ist somit einerseits mit der Kolbenstange 25 fest verbunden, andererseits über die Scheibe 43 und den Bolzen 44 mit geringem axialem und radialem Spiel mit dem Joch 19.So that no rotation of the piston rod is possible due to the eccentric movement acting on the piston rod 25, a compensating coupling 39 is provided between the yoke 19 and the piston rod 25. This consists essentially of a cylindrical body 40 which is screwed onto the piston rod 25 by means of a screw bolt 41 and a nut 42 arranged at its end. The cylindrical body 40 has a transverse slot 45, into which a disk 43 is inserted with a bolt 44 which extends toward the yoke and which is screwed to the yoke by means of a screw 46 arranged therein. The cylindrical body 40 is thus firmly connected on the one hand to the piston rod 25, and on the other hand via the disk 43 and the bolt 44 with little axial and radial play with the yoke 19.
