Abstract
Description
Druck ittelbetriebene KlemmvorrichtungPressure medium-operated clamping device
Die vorliegende Erfindung betrifft eine Vorrichtung zum Klemmen von langgestreckten Körpern mit gleichförmigen Quer- dimensionen, wie Stäben, Rohren, Seilen und dergleichen mittels Flüssigkeits- oder Gasdruck nach dem Oerbegriff des Patentanspruches 1.The present invention relates to a device for clamping elongated bodies with uniform transverse dimensions, such as rods, pipes, ropes and the like, by means of liquid or gas pressure.
Klemmvorrichtungen für Werkstücke für den Vorschub oder allgemein den Transport von Werkstücken, Werkzeugen, Maschi- nenteilen, betrieben mit Druckgas - also pneumatisch - oder mit Druckflüssigkeit, also hydraulisch - zusa mengefasst durch Druckmittel, sind bekannt und verbreitet im Einsatz. Die Umsetzung von Druck in Klemmkraft geschieht zumeist über Druckzylinder und Hebelwerke. Solange die zu klemmenden Stücke über mindestens zwei parallele Flächen verfügen und/oder keine besonders empfindlichen Oberflächen aufweisen, sind solche bekannten Vorrichtungen tauglich. Probleme treten hingegen dann auf, wenn Stücke mit rundem bzw. Rundung aufweisenden oder ungeradzahlig polygonalem Querschnitt geklemmt werden sollen. Verschärft wird die Problematik besonders durch zu klemmende Stücke mit empfindlicher Oberfläche oder dadurch, dass solche Stücke aus empfindlichen Materialien wie Glas oder Kunststoff bestehen, die durch metallische Klemmvorrichtungen beeinträchtigt oder beschädigt werden können. Die Aufgabe, die durch die vorliegende Erfindung gelöst werden soll besteht in der Schaffung einer durch Druckmittel zu betätigenden Klemmvorrichtung für langgestreckte Stücke gleichförmigen Querschnitts, durch welche grosse, auf die ganze Oberfläche einwirkende Klemmkräfte möglich sind, ohne die Oberflächen der Stücke zu beeinträchtigen.Clamping devices for workpieces for the feed or in general for the transport of workpieces, tools, machine parts, operated with compressed gas - that is pneumatically - or with hydraulic fluid - that is, hydraulically - combined by pressure medium, are known and widely used. The conversion of pressure into clamping force mostly takes place via pressure cylinders and lever mechanisms. As long as the pieces to be clamped have at least two parallel surfaces and / or have no particularly sensitive surfaces, such known devices are suitable. Problems arise, however, when pieces with a round or rounded or odd-numbered polygonal cross section are to be clamped. The problem is particularly exacerbated by pieces to be clamped with a sensitive surface or by the fact that such pieces consist of sensitive materials such as glass or plastic, which can be impaired or damaged by metallic clamping devices. The object which is to be achieved by the present invention is to provide a clamping device for elongated pieces of uniform cross-section to be actuated by pressure medium, by means of which large clamping forces acting on the entire surface are possible without impairing the surfaces of the pieces.

The invention is explained in more detail with reference to the accompanying drawings. Show it

Fig. 8 eine Variante zur Form einer Hülse.Fig. 8 shows a variant of the shape of a sleeve.
Fig. 1 zeigt ein erstes Ausführungsbeispiel als Grundausführung des Erfindungsgedankens im Längsschnitt, Fig. 2 im Schnitt AA. Eine zylindrische Hülse 1 ist an den beiden Stirnseiten durch je eine Kappe 2 abgeschlossen, welche je ein zentrisches Loch 3 aufweisen zur Aufnahme beispielsweise eines Rundstabes, allgemein eines zu klemmenden Körpers 4. Im Zwischenraum zwischen der Hülse 1 und dem Körper 4 befinden sich zwei konzentrische Schläuche 5 aus einem Elastomer, welche an den Enden miteinander verbunden sind und damit ein torusförmigen Element bilden, das fortan Druckkörper 6 genannt wird. Am äusseren Schlauch 5 des Druckkörpers 6 ist ein Ventil 7 angebracht, über das der Innenraum des Druckkörpers 6 mit einem Druckmittel gefüllt und unter Druck gesetzt wer- den kann. Damit wird der innere Schlauch 5 gegen den Körper 4 gedrückt und klemmt diesen mittels Reibungskraft fest. Die gesamthaft auf den Körper 4 wirkende Reibungskraft beträgtFig. 1 shows a first embodiment as a basic embodiment of the inventive concept in longitudinal section, Fig. 2 in section AA. A cylindrical sleeve 1 is closed at the two end faces by a cap 2, each having a central hole 3 for receiving, for example, a round rod, generally a body 4 to be clamped. In the space between the sleeve 1 and the body 4 there are two concentric ones Hoses 5 made of an elastomer, which are connected to one another at the ends and thus form a toroidal element, which is henceforth called pressure body 6. A valve 7 is attached to the outer tube 5 of the pressure body 6, via which the interior of the pressure body 6 can be filled with a pressure medium and pressurized. So that the inner tube 5 is pressed against the body 4 and clamps it by means of frictional force. The total frictional force acting on the body 4 is
FR=D-π-L-fH-p woF R = D-π-Lf H -p wo
FR = ReibungskraftF R = frictional force
D = Durchmesser des Körpers 4 L = Klemm-Länge des Körpers 1 fH = Haftreibungsbeiwert zwischen äusserer Oberfläche des inneren Schlauches 5 und Oberfläche des Körpers 4 p = FluiddruckD = diameter of the body 4 L = clamping length of the body 1 f H = coefficient of static friction between the outer surface of the inner tube 5 and the surface of the body 4 p = fluid pressure
Als Körper 4 kann - ohne Aenderung der Vorrichtung - selbstverständlich auch ein Seil geklemmt werden; ebenfalls Stäbe mit polygonalen Querschnitten. Für das Klemmen von flachen, bandartigen Stücken müssen andere Kappen 2 und allenfalls entsprechend geformte Schläuche 5 eingesetzt werden, was möglich ist, ohne den zentralen Erfindungsgedanken zu verlassen. Um zu vermeiden, dass der Körper 4 während einer Vorschubbe- wegung den inneren Schlauch 5 berührt, kann dieser - und die stirnseitigen Verbindungen der Schläuche 5 - so ausgelegt sein, das der Druckköper 6, wenn drucklos, im wesentlichen an der Hülse 1 anliegt. Fig. 3 ist die Darstellung eines zweiten Ausführungsbeispie- les. Anstelle eines Druckkörpers 6 sind hier deren zwei im wesentlichen gleiche eingesetzt, die in axialer Richtung hintereinander geschaltet sind. Die Vorrichtung kann so ausgelegt werden, dass lediglich durch einen einzigen Druckkörper die vorgesehene Haftreibungskraft schon aufgebracht wird, der zweite also lediglich zur Redundanz vorgesehen ist. Die Druckmittelversorgung der Druckkörper 6 ist dann unabhängig gestaltet.As the body 4, a rope can of course also be clamped without changing the device; also bars with polygonal cross sections. For the clamping of flat, band-like pieces, other caps 2 and, if necessary, correspondingly shaped hoses 5 must be used, which is possible without departing from the central idea of the invention. In order to prevent the body 4 from touching the inner tube 5 during a feed movement, this can - and the end connections of the tubes 5 - be designed so that the pressure body 6, when depressurized, essentially rests on the sleeve 1. 3 is the representation of a second exemplary embodiment. Instead of a pressure body 6, two essentially the same are used here, which are connected in series in the axial direction. The device can be designed in such a way that the intended static friction force is already applied by only one pressure body, that is to say the second is only provided for redundancy. The pressure medium supply to the pressure body 6 is then designed independently.
Sind die Druckkörper 6 beispielsweise aus einem gewebearmierten Elastomer gefertigt, so ist beim Versagen eines Druckkör- pers 6 die Funktion der Klemmvorrichtung gemäss Fig. 3 gewährleistet .If, for example, the pressure elements 6 are made of a fabric-reinforced elastomer, the function of the clamping device according to FIG. 3 is guaranteed if a pressure element 6 fails.
Andernfalls, wenn ohne Gewebearmierung gearbeitet wird, ist zwischen den beiden Druckkörpern 6 eine Trennwand 8 vorgesehen, die an der Hülse 1 befestigt ist und ein zu jenem der Kappen 2 analoges Loch 3 aufweist, wie in Fig. 4 im Ausschnitt gezeigt.Otherwise, when working without fabric reinforcement, a partition 8 is provided between the two pressure elements 6, which is attached to the sleeve 1 and has a hole 3 analogous to that of the caps 2, as shown in FIG. 4 in the detail.
Im Ausführungsbeispiel gemäss Fig. 5 ist eine Vielzahl von Druckkörpern 6 hintereinander geschaltet. Jeder verfügt über einen eigenen Anschluss 9 für die Druckmittelversorgung. Nicht dargestellt ist die Versorgung und Verwaltung der Anschlüsse 9, von denen jedoch jeder über ein eigenes nicht dargestelltes Rückschlagventil verfügt. Damit kann mehrfache Redundanz bewirkt werden. Das zu Fig. 3 oder 4 über die Trennwand 8 gesagte gilt auch bei einer Vielzahl von Druckkörpern 6.In the exemplary embodiment according to FIG. 5, a large number of pressure bodies 6 are connected in series. Everyone has its own connection 9 for the pressure medium supply. Not shown is the supply and management of the connections 9, but each of which has its own check valve, not shown. Multiple redundancy can thus be achieved. 3 or 4 about the partition 8 also applies to a large number of pressure elements 6.
In Fig. 6 ist der Querschnitt eines dritten Ausführungsbei- spieles dargestellt. Hier sind zwei Druckkörper 10 vorgese- hen, die sich je über die ganze Länge der Hülse 1 erstrecken, aber je nur den halben Raum des Hülsenvolumens einnehmen. Jeder Druckkörper verfügt über einen eigenen Anschluss 9, wobei die Anschlüsse 9 in der Druckmittelverwaltung parallel geschaltet sind und somit den gleichen Druck aufweisen. Die Hülse 1 ist hier in zwei Halbschalen 11 aufgeteilt, die beispielsweise durch ein Scharnier 12 verbunden, und diesem gegenüber liegend, durch eine schematisch dargestellte Verriegelungsvorrichtung 13 verbunden sind. Als Variante dazu ist vorgesehen, die Halbschalen 11 durch zwei Verriegelungsvorrichtungen 13 zu verbinden, wodurch die Halbschalen völlig voneinander getrennt werden können. Mit dem Scharnier 12 ist die Klemmvorrichtung - wenn entriegelt - lediglich aufklappbar. Die im Querschnitt von Fig. 6 nicht dargestellten Kappen 2 sind ebenfalls geteilt und die so entstehenden Halbkappen je mit einer Halbschale 11 verbunden.6 shows the cross section of a third exemplary embodiment. Two pressure elements 10 are provided here, each extending over the entire length of the sleeve 1, but each occupying only half the space of the sleeve volume. Each pressure body has its own connection 9, the connections 9 being connected in parallel in the pressure medium management and thus having the same pressure. The sleeve 1 is here divided into two half-shells 11, which are connected, for example, by a hinge 12 and, opposite this, are connected by a schematically illustrated locking device 13. As a variant, it is provided that the half-shells 11 are connected by two locking devices 13, as a result of which the half-shells can be completely separated from one another. With the hinge 12, the clamping device - when unlocked - can only be opened. The caps 2, not shown in the cross section of FIG. 6, are also divided and the half caps thus created are each connected to a half shell 11.
Sowohl Scharnier 12 als auch Verriegelungsvorrichtung sind lediglich im Sinne von Beispielen und stark schematisiert dargestellt. Der Fachmann solcher Maschinenelemente kennt eine Fülle von möglichen Lösungen für allenfalls auch elek- tromechanisch oder durch Druckmittel zu betätigenden Schliess-Vorrichtungen mit scharnierähnlichen Elementen und Verriegelungen . Fig. 7 zeigt eine Erweiterung der Lösung nach Fig. 6 auf eine Vielzahl von Druckkörpern 10, jeder wiederum versehen mit einem Anschluss 9. Die Verwaltung des Druckmittels wird so vorgesehen, dass zur vorhandenen Redundanz bei Ausfall eines Druckkörpers 10 der gegenüberliegende ebenfalls drucklos gemacht wird, um den geklemmten Körper 4 zentrisch zu halten. Es ist selbstverständlich erfindungsgemäss, die Ausführungsform gemäss Fig. 7 mit jener gemäss Fig. 5 zu kombinieren. Dadurch wird der - in Fig. 1 - einzige Druckkörper 6 ersetzt durch eine doppelte, axiale und azimutale, Mannigfaltigkeit von Druckkörpern 10 mit entsprechender Redundanz bzw. Betriebssicherheit . Die zu Fig. 1 angestellte Berechnung der Haftreibungskraft behält auch für die anderen Ausführungsformen ihre Gültigkeit. Wird die Klemmvorrichtung - beispielsweise gemäss Fig. 6 - verwendet, um eine Seilbahnkabine an einem Seil festzuklemmen, so wird die so erzielte Haftreibungskraft die erforderliche Grosse leicht erreichen. Dies sei an einem Beispiel gezeigt. MitBoth hinge 12 and locking device are shown only in the sense of examples and in a highly schematic manner. Those skilled in the art of such machine elements are familiar with a plethora of possible solutions for locking devices with hinge-like elements and locks that can also be actuated electromechanically or by pressure medium. FIG. 7 shows an extension of the solution according to FIG. 6 to a multiplicity of pressure elements 10, each in turn provided with a connection 9. The management of the pressure medium is provided in such a way that for redundancy in the event of a failure Pressure body 10 of the opposite is also depressurized to keep the clamped body 4 centrally. It is of course according to the invention to combine the embodiment according to FIG. 7 with that according to FIG. 5. As a result, the only pressure body 6 in FIG. 1 is replaced by a double, axial and azimuthal, diversity of pressure bodies 10 with corresponding redundancy or operational reliability. The calculation of the static friction applied to FIG. 1 also remains valid for the other embodiments. If the clamping device - for example according to FIG. 6 - is used to clamp a cable car cabin to a cable, the static friction force thus achieved will easily reach the required size. This is shown using an example. With
D = 3 10~2 m e = 0 5mD = 3 10 ~ 2 me = 0 5m
= 0 8 fH= 0 8 f H
P = 1 106PaP = 1 10 6 Pa
FR = 3 10_2 - τπ-0.5-0.8-10 =38kFR = 3 10 _2 - τπ-0.5-0.8-10 = 38k
womit eine Seilbahnkabine von 10 kN Gewicht mit vierfacher Sicherheit vertikal gehoben werden kann.with which a cable car cabin with a weight of 10 kN can be lifted vertically with four times the safety.
Die Haftungskraft ist über den Wert fH direkt beeinflussbar; mit mikroporösen Kunststoffen sind fH -Werte >1 ohne weiteres möglich. Die Verwendung einer solchen Klemmvorrichtung als Seilklemme für eine Hängeseilbahn ist also ebenfalls erfin- dungsgemäss.The adhesive force can be influenced directly via the value f H ; with microporous plastics, f H values> 1 are easily possible. The use of such a clamping device as a cable clamp for a suspended cable car is therefore also in accordance with the invention.
In Fig. 8 ist eine in Bezug auf die beschriebenen Ausführungsbeispiele modifizierte Hülse 1 dargestellt. Hier sind die Kappen 2 in die Hülse 1 formlich integriert, so dass die Hülse gegen beide Enden hin verjüngt ist bis etwa auf den Durchmesser der Löcher 3. Das Ausführungsbeispiel weist beispielsweise zwei sich über die Länge der Hülse erstreckende Druckkörper 10 auf, welche je einen eigenen Anschluss 9 haben. Die Hülse 1 ist hier beispielsweise in zwei Halbschalen 11 aufgeteilt entlang der auf der Zeichenebene senkrecht stehenden Ebene. Die Anschlüsse 9 liegen je in einer zur genannten parallelen Ebene.FIG. 8 shows a sleeve 1 modified with respect to the described exemplary embodiments. Here, the caps 2 are formally integrated into the sleeve 1, so that the sleeve is tapered towards both ends, down to approximately the diameter of the holes 3. The exemplary embodiment has, for example, two pressure bodies 10 extending over the length of the sleeve, each of which have their own connection 9. The sleeve 1 is here, for example, in two half-shells 11 divided along the plane perpendicular to the plane of the drawing. The connections 9 each lie in a plane parallel to the mentioned one.
Wird die Klemmvorrichtung gemäss Fig. 8 zum Festklemmen einer Seilbahnkabine an einem Seil (Körper 4) verwendet, so ermöglicht die beidseitig verjüngte Form der Hülse 1 ein Ueberfah- ren von Seilrollen. Seilbahntechnische Details sind in Fig. 8 jedoch weggelassen, ebenso eine Darstellung der Verriegelungsvorrichtung aus den vorstehend dargelegten Gründen. If the clamping device according to FIG. 8 is used to clamp a cable car cabin to a cable (body 4), the shape of the sleeve 1, which is tapered on both sides, enables cable pulleys to be passed over. Cable car details are omitted in FIG. 8, however, as is an illustration of the locking device for the reasons set out above.
