Abstract

A working cylinder (1) is equipped with a braking and positioning device (7) which is coupled to its power take-off (5) and interacts with a profile of a machine, apparatus or the like, which runs on the two cylinder heads (2, 3) of the working cylinder (1) or runs parallel to the latter. The braking device can be set up for operation when there is a build-up or drop in pressure in the brake system and can thus satisfy a large variation of requirements. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Arbeitszylinder mit einer Bremseinrichtung, vorzugsweise zum Anhalten, Feststellen und Positionieren von fluidgetriebenen Antrieben, die am Kraftübertragungsglied, beispielsweise einem Band, Zapfen oder dergl. oder in der Kraftabnahme angeordnet ist.The invention relates to a power cylinder with a braking device, preferably for stopping, fixing and positioning fluid-driven drives, which is arranged on the force transmission element, for example a belt, pin or the like, or in the power take-off.

Ein solcher Arbeitszylinder mit Bremseinrichtung ist aus der DE, OS 2945133 bekannt. Dabei umfaßt die Bremseinrichtung mit mindestens einem Bremsbelag das Zylinderrohr des Arbeitszylinders konzentrisch und ist in die Kraftabnahme integriert.Such a working cylinder with a braking device is known from DE, OS 2945133. The brake device concentrically comprises the cylinder tube of the working cylinder with at least one brake pad and is integrated in the power take-off.

Für bestimmte Anwendungsfälle, beispielsweise wenn die Aussenkontur des Zylinderrohres keine Rohrform aufweist oder aus sonstigen Spezialprofilen besteht, bzw. aus anderen Gründen nicht als Bremsfläche genutzt werden kann; beispielsweise weil ein solches Spezialprofil gleichzeitig zum Führen der Kraftabnahme dient, oder wenn zusätzlich Schaltvorgänge auszulösen sind, muß für die Anordnung der Bremse eine andere Lösung gefunden werden.For certain applications, for example if the outer contour of the cylinder tube is not tubular or consists of other special profiles, or cannot be used as a braking surface for other reasons; for example, because such a special profile is used at the same time for guiding the power take-off, or if additional switching operations are to be triggered, another solution must be found for the arrangement of the brake.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Arbeitszylinder mit einer Bremseinrichtung zu besitzen, die universell einsetzbar ist und ein Angreifen der Bremselemente nicht auf die Oberfläche des Arbeitszylinders beschränkt.The invention is therefore based on the object of having a working cylinder with a braking device which can be used universally and does not restrict attack on the braking elements to the surface of the working cylinder.

Erfindungsgemäß wird dies dadurch erreicht, daß die Bremseinrichtung mit der Kraftabnahme gekoppelt ist und sich zumindest mit einem Bremsbelag an einem parallel zum Arbeitszylinder verlaufenden Profil abstützt.According to the invention, this is achieved in that the braking device is coupled to the power take-off and is supported at least with one brake pad on a profile running parallel to the working cylinder.

Vorteilhafterweise ist das Profil als Bremsfläche ausgebildet. Vorteilhafterweise stützt sich der Bremsbelag auf einem Bauteil der Maschine oder dergl. ab, in die der Arbeitszylinder eingebaut ist.The profile is advantageously designed as a braking surface. The brake lining is advantageously supported on a component of the machine or the like in which the working cylinder is installed.

Eine Ausführungsvariante sieht vor, daß die Bremseinrichtung mit der Kraftabnahme des Arbeitszylinders über eine Halterung verbunden ist.An embodiment variant provides that the braking device is connected to the power take-off of the working cylinder via a holder.

Die Erfindung ist nachstehend anhand eines in den Abbildungen dargestellten Ausführungsbeispieles näher erläutert.The invention is explained below with reference to an embodiment shown in the figures.

Es zeigt:

  • Fig. 1 eine perspektivische Darstellung des Arbeitzylinders,
  • Fig. 2 einen Schnitt durch die Bremseinrichtung und
  • Fig. 3 einen Schnitt durch eine Ausführungsvariante der Fig. 2
  • Fig. 4 eine Ausführungsvariante der Fig. 1
It shows:
  • 1 is a perspective view of the working cylinder,
  • Fig. 2 shows a section through the braking device and
  • 3 shows a section through an embodiment variant of FIG. 2
  • 4 shows an embodiment variant of FIG. 1

Der in den Abbildungen dargestellte Arbeitszylinder besteht im wesentlichen aus einem Zylinderrohr 1 mit seinen beiden Zylinderköpfen 2 und 3. Das Kraftübertragungsglied 4, beispielsweise eine Kraftbrücke, ist innen im Zylinderrohr 1 mit einem nicht dargestellten, durch Druckkraft hin- und her bewegbaren Kolben verbunden.The working cylinder shown in the figures consists essentially of a cylinder tube 1 with its two cylinder heads 2 and 3. The force transmission element 4, for example a power bridge, is connected inside the cylinder tube 1 to a piston (not shown) that can be moved back and forth by pressure force.

Am Zylinderrohr 1 läuft außen eine Kraftabnahme 5, die.ihrerseits über eine Halterung 6 die eigentliche Bremseinrichtung 7 trägt. Anstelle einer Halterung 6 kann die Bremseinrichtung 7 auch Teil der Kraftabnahme 5 sein.On the outside of the cylinder tube 1 there is a decrease in force 5 which, on its part, carries the actual braking device 7 via a holder 6. Instead of a holder 6, the braking device 7 can also be part of the power take-off 5.

Die Bremseinrichtung 7 wirkt auf ein Profil ein, das an beiden Zylinderköpfen 2 und 3 befestigt ist. Diese Bremseinrichtung kann entweder als bei Druckbeaufschlagung wirksame Bremse 7a (Fig. 2) oder als bei Druckabbau wirksame Bremse 7b (Fig. 3) ausgebildet sein.The braking device 7 acts on a profile which is attached to both cylinder heads 2 and 3. This braking device can either be designed as a brake 7a (FIG. 2) which acts when pressure is applied or as a brake 7b (FIG. 3) which acts when pressure is reduced.

Die Bremseinrichtung 7a, die aus Fig. 2 hervorgeht, besitzt ein Gehäuse 9, das beispielsweise aus zwei Teilen besteht, die mittels Schrauben 10 und Muttern 11 zusammengehalten sind.The braking device 7a, which emerges from FIG. 2, has a Housing 9, which consists for example of two parts, which are held together by means of screws 10 and nuts 11.

Im Inneren des Gehäuses 9 befindet sich ein fluidbetätigter Balg 12, der bei Druckbeaufschlagung über eine Distanzplatte 13 auf den Bremsbelag 14a einwirkt und diesen gegen das Profil 8 presst, wodurch dieses auch gegen den Bremsbelag 14b gepresst wird,folglich eine wirksame Abbremsung der Kraftabnahme 5 eintritt. Somit sind beispielsweise genaue Positionierungen der Kraftabnahme bei Druckaufbau im Balg 12 möglich.Inside the housing 9 there is a fluid-actuated bellows 12, which acts on the brake pad 14a when pressure is applied via a spacer plate 13 and presses it against the profile 8, as a result of which this is also pressed against the brake pad 14b, consequently an effective braking of the power take-off 5 occurs . Thus, for example, precise positioning of the decrease in force when pressure builds up in bellows 12 is possible.

Die Fig. 3 zeigt eine Ausführungsvariante der Bremseinrichtung 7b, die, im Gegensatz zu der in Fig. 2 dargestellten, bei Druckabbau, bzw. Druckausfall im fluidbetätigten Balg 12 in ihre Wirkstellung geht. Zwischen dem oberen 9a und unteren Teil 9b des Gehäuses 9 ist bei dieser Ausführungsvariante eine Zwischenplatte 15 eingefügt, während zwischen den Muttern 11 und dem oberen Gehäuseteil 9a Tellerfedern 16 eingesetzt sind. Eine Distanzplatte 17 mit mindestens zwei Zapfen 18a und 18b ist zwischen dem Balg 12 und der Zwischenplatte 15 eingesetzt, die sich mit den Zapfen 18a und 18 am unteren Gehäuseteil 9b abstützt.FIG. 3 shows an embodiment variant of the braking device 7b, which, in contrast to the one shown in FIG. 2, goes into its active position when the pressure is reduced or pressure drops in the fluid-actuated bellows 12. In this embodiment variant, an intermediate plate 15 is inserted between the upper part 9a and the lower part 9b of the housing 9, while disk springs 16 are inserted between the nuts 11 and the upper part 9a of the housing. A spacer plate 17 with at least two pins 18a and 18b is inserted between the bellows 12 and the intermediate plate 15, which is supported with the pins 18a and 18 on the lower housing part 9b.

Solange der fluidbetätigte Balg 12 unter Druck steht, wird das obere Gehäuseteil 9a gegen den Druck der Tellerfedern 16 angehoben, wodurch die Bremsbeläge 14a und 14b entlastet sind, da die Distanzplatte 17, worauf sich der Balg abstützt, mit ihren Zapfen 18a und 18b gegen das untere Gehäuseteil 9b gedrückt und somit auf Distanz gehalten wird. Die Bremsbeläge 14a und 14b werden dagegen bei Druckausfall bzw. Druckabbau im Balg 12 wirksam gegen das zwischen ihnen befindliche Profil 8 gedrückt, indem die Tellerfedern 16 das obere Gehäuseteil 9a gegen die Zwischenplatte 15 und über diese denAs long as the fluid-actuated bellows 12 is under pressure, the upper housing part 9a is raised against the pressure of the plate springs 16, whereby the brake pads 14a and 14b are relieved, since the spacer plate 17, on which the bellows is supported, with its pins 18a and 18b against it lower housing part 9b pressed and thus kept at a distance. The brake pads 14a and 14b, on the other hand, are effectively pressed against the profile 8 located between them in the event of pressure loss or pressure reduction in the bellows 12, by the plate springs 16, the upper housing part 9a against the intermediate plate 15 and the latter

Bremsbelag 14 gegen das Profil 8 drücken. Das Profil 8 dient dabei zwischen den beiden Bremsbelägen 14a und 14b als Bremsfläche; denn der Bremsbelag 14b befindet sich auf der Innenseite des unteren Gehäuseteiles 9. Die Zwischenplatte 15 ist an den Stellen der Zapfen 18a und 18b mit Aussparungen versehen, sodaß sie sich nach unten auf den Bremsbelag 14a zubewegen kann, bzw. bei Druckaufbau im Balg 12 die Distanzplatte 17 sich am Boden des unteren Gehäuses 9b abstützen kann und somit die Bremsbeläge 14a und 14b entlastet.Press brake pad 14 against profile 8. The profile 8 serves between the two brake pads 14a and 14b as a braking surface; because the brake pad 14b is located on the inside of the lower housing part 9. The intermediate plate 15 is provided with recesses at the locations of the pins 18a and 18b so that it can move downward towards the brake pad 14a, or when the bellows 12 builds up pressure Spacer plate 17 can be supported on the bottom of the lower housing 9b and thus relieves the brake pads 14a and 14b.

Die in Fig. 4 dargestellte Ausführungsvariante der Fig. 1 zeigt einen Arbeitszylinder 1, dessen Kraftabnahme 5 ebenfalls mit einer Bremseinrichtung 7 ausgerüstet ist, die jedoch mit einem Profil 19 zusammenarbeitet, das beispielsweise Bestandteil einer Maschine, Vorrichtung oder dergleichen ist, in die der Arbeitszylinder eingebaut ist.The embodiment variant of FIG. 1 shown in FIG. 1 shows a working cylinder 1, the power take-off 5 of which is also equipped with a braking device 7, which, however, cooperates with a profile 19, which is part of a machine, device or the like, for example, into which the working cylinder is installed.

Durch die mit der Erfindung vorgeschlagene Anordnung der Bremseinrichtung an Fluidzylindern können auch solche Anwendungsfälle beherrscht werden, die z.B. eine Nutzung der Zy-. linderoberfläche als Bremsfläche nicht zulassen, oder, wenn seitliche Momente von der Kraftabnahme aufgenommen werden müßen.The proposed invention with the arrangement of the brake means of fluid cylinders also such applications may be controlled, for example, the use of the Zy -. Do not allow a linder surface as a braking surface, or if lateral moments have to be absorbed by the power take-off.
