Aufgabe der vorliegenden Erfindung ist es, eine Betätigungseinrichtung zu realisieren, die sich einerseits gut montieren lässt aber auch hinsichtlich der Herstellung der Einzelteile einen vertretbaren Aufwand mit sich bringt.task of the present invention is to realize an actuating device which is easy to assemble on the one hand but also in terms of Manufacturing the individual parts with a reasonable effort brings.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass das Ringteil und das Verschiebestück im Bereich der zentralen Öffnung im Bereich ihrer zugewandten Klemmflächen mittels einer Pressverbindung zueinander fixiert sind.According to the Task solved by that the ring part and the sliding piece in the area of the central opening in Area of their facing clamping surfaces by means of a press connection are fixed to each other.
Aufgrund der Pressverbindung zwischen dem Verschiebeteil und dem Ringteil kann trotz der geteilten Bauweise des Kolbens eine Vereinfachung der Montage erreicht werden, da diese Baugruppe unabhängig vom Zylinder hergestellt wird und anschließend leicht handhabbar in den Zylinder eingeführt werden kann.by virtue of the press connection between the sliding part and the ring part can simplify the despite the divided design of the piston Assembly can be achieved because this assembly regardless of Is produced and then easy to handle in the cylinder Cylinder introduced can be.
Um eine möglichst große Klemmfläche und Winkelgenauigkeit des Ringteils zum Verschiebestück zu erreichen, weist das Ringteil im Bereich der Durchgangsöffnung eine zylindrischen Klemmhülse auf, die auf dem Verschiebestück aufsitzt.Around one if possible size clamping surface and to achieve angular accuracy of the ring part to the sliding piece, the ring part has a cylindrical clamping sleeve in the area of the through opening, the one on the sliding piece seated.
Um unter allen Umständen einen Positionierungsfehler des Verschiebestücks zum Ringteil zu vermeiden, weist das Verschiebestück außerhalb des Arbeitsraums eine Anschlagfläche für das Ringteil auf.Around under all circumstances to avoid a positioning error of the sliding piece relative to the ring part, shows the sliding piece outside of Work area a stop surface for the Ring part on.
Zusätzlich zu der bereits vorhandenen Dichtwirkung aufgrund der Pressverbindung zwischen dem Verschiebestück und dem Ringteil ist innerhalb einer der Klemmflächen der Pressverbindung eine Dichtung einlegt. Die Dichtung muss nicht unbedingt als geometrisch bestimmter Körper, sondern kann auch als formbare Masse ausgeführt sein.In addition to the existing sealing effect due to the press connection between the sliding piece and the ring member is a seal within one of the clamping surfaces of the press connection inserts. The seal does not necessarily have to be geometrically specific Body, but can also be designed as a moldable mass.
Zur eindeutigen Bestimmung der Position des Ringteils in beide Achsrichtungen der Verschiebebewegung des Kolbens ist das Ringteil zwischen der Anschlagfläche außerhalb des Arbeitsraums und einer zweiten Sicherungsfläche des Verschiebestücks axial fixiert.to unambiguous determination of the position of the ring part in both axial directions the displacement movement of the piston is the ring part between the stop surface outside of the working space and a second securing surface of the sliding piece axially fixed.
Bei einer Ausführungsform ist die Klemmfläche des Verschiebestücks axial länger ausgeführt als die Klemmhülse des Ringteils, wobei durch zumindest partielles Umformen der Klemmfläche in Richtung der Klemmhülse die Sicherungsfläche hergestellt wird. Diese axiale Sicherung ist spielfrei und benötigt keine zusätzlichen Fixierungsmittel, wie z. B. einen Sicherungsring der grundsätzlich ebenfalls sinnvoll wäre.at one embodiment is the clamping surface of the sliding piece axially longer accomplished than the ferrule of the ring part, whereby by at least partially reshaping the clamping surface in the direction the clamping sleeve the security area will be produced. This axial securing is free of play and does not require any additional Fixing agents, such as. B. a snap ring which is also generally useful would.
Man kann aber auch vorsehen, dass die Klemmfläche des Verschiebestücks mindestens eine Vertiefung aufweist, in die ein Teil der Klemmhülse eingeformt ist. Diese Variante bietet den Vorteil, dass das Ringteil axial und in Umfangsrichtung zum Verschiebeteil fixiert ist. Die Vertiefung in dem Verschiebestück kann auch als Nut umlaufend ausgeführt und der Kolben in diese Nut eingerollt sein, Als weitere Möglichkeit wird vorgeschlagen, dass mindestens eine der Klemmflächen am Verschiebestück oder der Klemmhülse mit einem Schneidprofil ausgeführt ist, das sich in die andere Klemmfläche eingräbt. Ein derartiges Schneidprofil erlaubt eine Vergrößerung der zulässigen Fertigungstoleranzen, da das Schneidprofil einen entsprechenden Ausgleich aufgrund der Tiefe des Schneidprofils bietet.you can also provide that the clamping surface of the sliding piece at least has a recess into which a part of the clamping sleeve is molded is. This variant has the advantage that the ring part is axial and is fixed in the circumferential direction to the sliding part. The deepening in the sliding piece can also run as a groove and the piston in this Groove should be rolled in. Another possibility is proposed that at least one of the clamping surfaces on the sliding piece or the clamping sleeve executed with a cutting profile that digs into the other clamping surface. Such a cutting profile allows an increase in the permissible manufacturing tolerances, because the cutting profile has a corresponding compensation due to the depth of the cutting profile.
