Definitions
- the invention relates to a toggle lever device with the features of the preamble of claim 1.
- Toggle clamps are widely known in the art and find particular use in the bodywork of the automotive industry.
- the toggle clamping devices have in particular a chuck, a clamping arm pivotally mounted in the clamping head and a drive with an actuating part which is connected to the clamping head on.
- This drive is, for example, a piston-cylinder unit to be acted upon alternately on both sides by pressure medium pressure, a linear motor or a linear electric motor which drives a rod back and forth in its longitudinal direction.
- the reciprocally adjustable rod is formed from two bar parts screwed together, whereby the rod can be extended or shortened.
- a toggle clamping device with the features of the preamble of claim 1 is known from EP 0 908 272 A1 known.
- a first rod part is pivotally connected to the toggle lever assembly and a second rod part mounted in a linearly adjustable control part of the drive.
- the first rod part has an externally threaded portion and the second rod part has an internally threaded portion.
- the first rod part receives a first switching element and the clamping head is provided with a first interrogator for detecting an end position of the first switching element.
- the second rod part receives a second switching element and the clamping head is provided with a second interrogator for detecting an end position of the second switching element.
- the two switching elements are moved linearly when the rod is moved back and forth.
- the housing of the drive In this toggle clamping device, the housing of the drive must be released from the clamping head to adjust the length of the rod. Thus, after removing screws which serve to connect the housing of the drive to the housing of the clamping head, the housing of the drive can be rotated together with the rod relative to the housing of the clamping head about the longitudinal axis of the rod to a predetermined angle of rotation, which Reinstallation of the housing of the drive on the housing of the clamping head allows. If the housing of the drive has a square cross-section and the holes for the fastening screws are provided in the region of the corners of the housing, a rotation of the housing of the drive relative to the housing of the clamping head is at angles one or more times a 90 ° angle , possible.
- the two provided in this toggle lever switching elements are formed as flags, which interact with inductive End einsabfrage wornen associated with the housing of the clamping head.
- the two switching elements With a minimum length of the rod, the two switching elements are arranged at a distance from each other, thus the first switching element substantially closer to the toggle lever arrangement than the second switching element.
- this clamping device requires a considerable space axially.
- the first switching element is also freely rotatably mounted to allow rotation of the drive and adjustable in the housing actuator - piston-cylinder unit -.
- the piston is designed, for example, rectangular in cross section.
- toggle-type tensioning device in which the first rod member connected to the toggle assembly has an internal thread and the second rod member connected to the actuator of the actuator is externally threaded. Also in this device, two interrogators are provided for detecting the end positions of the toggle clamping device, wherein cooperates with these two interrogators designed as a switching flag switching element and thus indicates the position of the rod and thus indirectly also the opening angle of the clamping arm.
- the interrogators are, in particular, inductively operating sensors, microswitches or pneumatic switches.
- the drive on its side facing away from the clamping head on an opening through which, for the purpose of length change of the rod, the second rod member rotatable about its longitudinal axis relative to the housing of the drive is. Consequently, to change the length of the rod, the housing of the drive does not need to be disassembled from the housing of the chuck.
- a toggle clamping device is further in the EP 1 262 285 A2 described.
- Object of the present invention is to provide a toggle lever device with the features of the preamble of claim 1 so on that it has a particularly compact length and allows infinitesimal adjustment of the opening angle of the toggle lever device.
- the opening angle of the toggle lever device can be adjusted because the drive on its side facing away from the clamping head has the opening through which, for the purpose of length adjustment of the rod, the second rod member is rotatable about its longitudinal axis relative to the housing of the drive. It is therefore not necessary to separate the housing of the drive from the housing of the clamping head.
- the stepless adjustment of the opening angle of the toggle lever device is possible due to the formation of the rod with the telescoping rod parts. With a correspondingly fine thread pitch, an infinitesimal adjustment of the opening angle of the toggle lever clamping device, thus adjustment of the tensioning arm, is possible.
- the toggle clamping device is structurally particularly compact, because the second shifting element is rotatable relative to the second rod part about its longitudinal axis and axially fixed in this rod part, and the two switching elements occupy at least an overlapping position at maximum bolted rod parts.
- the position of the second switching element changes only in the axial direction of the second rod part.
- the second switching element is preferably linearly guided, in particular guided in the housing of the clamping head and thus does not rotate when turning the second rod part.
- the two switching elements occupy at least an overlapping position with maximally interlocked rod parts
- the two interrogators which are engageable with the two switching elements operatively connected, are placed much closer to each other than in an arrangement of the switching elements, the spaced apart with each other bar members spaced apart are arranged.
- the two switching elements take at least the overlapping position. This means that the switching elements could in principle also be moved beyond this overlapping position.
- the overlapping position is considered transversely to the direction of travel of the two switching elements, thus transversely to the longitudinal extent of the toggle lever tensioning device.
- the first switching element is rigidly connected to the first rod part.
- This rigid connection of the first switching element with the first rod part is therefore fundamentally possible and is considered advantageous because the first rod part is not rotatable, but only the second rod part.
- one of the two switching elements substantially plate-shaped and the other switching element is formed substantially U-shaped, such that at maximum nested rod parts, the plate-shaped switching element is retracted into the U-shaped switching element.
- the space between the two legs of the U is therefore suitable to receive the substantially plate-shaped switching element. This can, depending on the extent of the plate in the direction of the longitudinal direction of the rod, take the overlapping position with maximally nested rod parts overlapping position with the U of the other switching element or even occupy a position in which the U-shaped switching element has been run over by the plate-shaped switching element.
- the respective switching element is designed in particular as a flag.
- the respective interrogator can be designed in different ways, especially under the aspect of their mode of action.
- the respective interrogation device has a switch which can be swiveled or tilted by means of the respective switching element, preferably a limit switch, in particular a pneumatic limit switch.
- a limit switch in particular a pneumatic limit switch.
- the respective interrogator has an actuatable by the respective switching element electronic limit switch or optical reader.
- the first interrogator is used to detect the clamping position of the clamping arm and the second interrogator detecting the release position of the clamping arm.
- the two rod parts can be designed differently; it is only necessary that the first rod part has the section with the external thread and the second rod part has the section with the internal thread.
- the first rod part has a threaded bolt and a fork.
- the threaded bolt is pivotally connected to the fork.
- the fork is preferably guided in the longitudinal direction of the toggle lever clamping device and takes in the region of its end facing away from the threaded bolt pivotally the toggle lever assembly on.
- the fork receives the first switching element.
- the second rod part and the actuating part of the drive form, for example, a structural unit or the second rod part is fixed axially and in this case mounted rotatably or non-rotatably in the actuating part of the drive.
- the embodiments of the toggle lever clamping device 1 shown in the figures are used in particular in the bodywork of the motor vehicle industry.
- the toggle clamping device 1 has a clamping head 2 and a clamping arm 3 pivotally mounted in the clamping head. This is rotatably connected to a shaft 4, which is mounted in the housing 5 of the clamping head 2 and out of the housing 5 out.
- a drive 6 is connected.
- This has an axially back and forth adjustable rod 7.
- a knee lever assembly 8 connects the rod 7 with the shaft 4 and thus the clamping arm 3.
- the toggle lever assembly comprises a lever 9 and a lever 10.
- the lever 9 is rotatably connected at one end to the shaft 4 and it is hinged at the other end of the lever 9 of the lever 10 by means of an axis 11 pivotally.

Description
Die Erfindung betrifft eine Kniehebelspannvorrichtung mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a toggle lever device with the features of the preamble of
Kniehebelspannvorrichtungen sind vielfältig aus dem Stand der Technik bekannt und finden insbesondere Verwendung im Karosseriebau der Kraftfahrzeug-Industrie.Toggle clamps are widely known in the art and find particular use in the bodywork of the automotive industry.
Die Kniehebelspannvorrichtungen weisen insbesondere einen Spannkopf, einen im Spannkopf schwenkbar gelagerten Spannarm und einen Antrieb mit einem Stellteil, das mit dem Spannkopf verbunden ist, auf. Bei diesem Antrieb handelt es sich beispielsweise um eine abwechselnd beidseitig durch Druckmitteldruck zu beaufschlagende Kolben-Zylinder-Einheit, einen Linearmotor oder einen Linear-Elektromotor, der eine Stange in deren Längsrichtung hin und her antreibt. Zum Verstellen des Öffnungswinkels der Kniehebelspannvorrichtung, somit des Winkels des Spannarms, bezogen auf die Position des Antriebs, ist die hin- und her verstellbare Stange aus zwei ineinandergeschraubten Stangenteilen gebildet, womit die Stange verlängert oder verkürzt werden kann.The toggle clamping devices have in particular a chuck, a clamping arm pivotally mounted in the clamping head and a drive with an actuating part which is connected to the clamping head on. This drive is, for example, a piston-cylinder unit to be acted upon alternately on both sides by pressure medium pressure, a linear motor or a linear electric motor which drives a rod back and forth in its longitudinal direction. To adjust the opening angle of the toggle lever tensioning device, thus the angle of the tensioning arm, based on the position of the drive, the reciprocally adjustable rod is formed from two bar parts screwed together, whereby the rod can be extended or shortened.
Eine Kniehebelspannvorrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 ist aus der
Bei dieser Kniehebelspannvorrichtung muss zum Verstellen der Länge der Stange das Gehäuse des Antriebs vom Spannkopf gelöst werden. So kann nach dem Entfernen von Schrauben, die dem Verbinden des Gehäuses des Antriebs mit dem Gehäuse des Spannkopfs dienen, das Gehäuse des Antriebs zusammen mit der Stange relativ zum Gehäuse des Spannkopfs um die Längsachse der Stange gedreht werden, um einen vorgegebenen Drehwinkel, der die erneute Befestigung des Gehäuse des Antriebs am Gehäuse des Spannkopfes ermöglicht. Weist das Gehäuse des Antriebs quadratischen Querschnitt auf und sind im Bereich der Ecken des Gehäuses die Bohrungen für die Befestigungsschrauben vorgesehen, ist eine Verdrehung des Gehäuses des Antriebs relativ zum Gehäuse des Spannkopfes um Winkel, die dem ein- oder mehrfachen eines 90°-Winkel entsprechen, möglich. Entsprechend diesem 90°-Winkel ist eine minimale Verstellung der beiden Stangenteile zueinander möglich, womit keine infinitesimale Verstellung des Öffnungswinkels der Kniehebelspannvorrichtung möglich ist. Die beiden bei dieser Kniehebelspannvorrichtung vorgesehenen Schaltelemente sind als Fahnen ausgebildet, die mit induktiven Endstellungsabfrageeinrichtungen zusammenwirken, die dem Gehäuse des Spannkopfs zugeordnet sind. Bei minimaler Länge der Stange sind die beiden Schaltelemente in Abstand zueinander angeordnet, somit das erste Schaltelement wesentlich näher zur Kniehebelanordnung als das zweite Schaltelement. Demzufolge benötigt diese Spannvorrichtung axial einen erheblichen Bauraum. Das erste Schaltelement ist zudem frei drehbar montiert, um eine Drehung des Antriebs und des im Gehäuse verstellbaren Stellteils - Kolben-Zylinder-Einheit - zuzulassen. Der Kolben ist beispielsweise im Querschnitt rechteckig gestaltet.In this toggle clamping device, the housing of the drive must be released from the clamping head to adjust the length of the rod. Thus, after removing screws which serve to connect the housing of the drive to the housing of the clamping head, the housing of the drive can be rotated together with the rod relative to the housing of the clamping head about the longitudinal axis of the rod to a predetermined angle of rotation, which Reinstallation of the housing of the drive on the housing of the clamping head allows. If the housing of the drive has a square cross-section and the holes for the fastening screws are provided in the region of the corners of the housing, a rotation of the housing of the drive relative to the housing of the clamping head is at angles one or more times a 90 ° angle , possible. According to this 90 ° angle, a minimum adjustment of the two rod parts to each other is possible, whereby no infinitesimal adjustment of the opening angle of the toggle lever clamping device is possible. The two provided in this toggle lever switching elements are formed as flags, which interact with inductive Endstellungsabfrageeinrichtungen associated with the housing of the clamping head. With a minimum length of the rod, the two switching elements are arranged at a distance from each other, thus the first switching element substantially closer to the toggle lever arrangement than the second switching element. As a result, this clamping device requires a considerable space axially. The first switching element is also freely rotatably mounted to allow rotation of the drive and adjustable in the housing actuator - piston-cylinder unit -. The piston is designed, for example, rectangular in cross section.

Aufgabe der vorliegenden Erfindung ist es, eine Kniehebelspannvorrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 so weiter zu bilden, dass diese eine besonders kompakte Baulänge aufweist und eine infinitesimale Verstellung des Öffnungswinkels der Kniehebelspannvorrichtung gestattet.Object of the present invention is to provide a toggle lever device with the features of the preamble of
Gelöst wird die Aufgabe durch eine Kniehebelspannvorrichtung, die gemäß den Merkmalen des Patentanspruchs 1 ausgebildet ist.The problem is solved by a toggle lever device, which is designed according to the features of
Besonders schnell und einfach lässt sich der Öffnungswinkel der Kniehebelspannvorrichtung verstellen, weil der Antrieb auf seiner dem Spannkopf abgewandten Seite die Öffnung aufweist, durch die, zwecks Längenverstellung der Stange, das zweite Stangenteil um seine Längsachse relativ zum Gehäuse des Antriebs drehbar ist. Es ist somit nicht erforderlich, das Gehäuse des Antriebs vom Gehäuse des Spannkopfs zu trennen.Particularly quickly and easily, the opening angle of the toggle lever device can be adjusted because the drive on its side facing away from the clamping head has the opening through which, for the purpose of length adjustment of the rod, the second rod member is rotatable about its longitudinal axis relative to the housing of the drive. It is therefore not necessary to separate the housing of the drive from the housing of the clamping head.
Die stufenlose Verstellung des Öffnungswinkels der Kniehebelspannvorrichtung ist aufgrund der Ausbildung der Stange mit den ineinander schraubbaren Stangenteilen möglich. Bei entsprechend feiner Gewindesteigung ist eine infinitesimale Verstellung des Öffnungswinkels der Kniehebelspannvorrichtung, somit Verstellung des Spannarms möglich.The stepless adjustment of the opening angle of the toggle lever device is possible due to the formation of the rod with the telescoping rod parts. With a correspondingly fine thread pitch, an infinitesimal adjustment of the opening angle of the toggle lever clamping device, thus adjustment of the tensioning arm, is possible.
In ihrer Länge ist die Kniehebelspannvorrichtung baulich besonders kompakt, weil das zweite Schaltelement relativ zum zweiten Stangenteil um dessen Längsachse drehbar und in diesem Stangenteil axial festgelegt gelagert ist und die beiden Schaltelemente bei maximal ineinandergeschraubten Stangenteilen zumindest eine überlappende Stellung einnehmen. Beim Verstellen der beiden Stangenteile zueinander, somit dem Verdrehen des zweiten Stangenteits, verändert sich die Position des zweiten Schaltelements nur in Axialrichtung des zweiten Stangenteils. Das zweite Schaltelement ist vorzugsweise linear geführt, insbesondere im Gehäuse des Spannkopfs geführt und dreht sich demnach beim Drehen des zweiten Stangenteils nicht mit. Dadurch, dass die beiden Schaltelemente bei maximal ineinandergeschraubten Stangenteilen zumindest eine überlappende Stellung einnehmen, können die beiden Abfrageeinrichtungen, die mit den beiden Schaltelementen in Wirkverbindung bringbar sind, wesentlich dichter zueinander platziert werden als bei einer Anordnung der Schaltelemente, die bei maximal ineinandergeschraubten Stangenteilen beabstandet zueinander angeordnet sind. In der maximal ineinandergeschraubten Stellung der Stangenteile nehmen die beiden Schaltelemente zumindest die überlappende Stellung ein. Dies bedeutet, dass die Schaltelemente grundsätzlich auch über diese überlappende Position hinaus verfahren werden könnten. Die überlappende Stellung ist quer zur Verfahrrichtung der beiden Schaltelemente betrachtet, somit quer zur Längserstreckung der Kniehebelspannvorrichtung.In terms of length, the toggle clamping device is structurally particularly compact, because the second shifting element is rotatable relative to the second rod part about its longitudinal axis and axially fixed in this rod part, and the two switching elements occupy at least an overlapping position at maximum bolted rod parts. When adjusting the two rod parts to each other, thus the rotation of the second rod side, the position of the second switching element changes only in the axial direction of the second rod part. The second switching element is preferably linearly guided, in particular guided in the housing of the clamping head and thus does not rotate when turning the second rod part. Characterized in that the two switching elements occupy at least an overlapping position with maximally interlocked rod parts, the two interrogators, which are engageable with the two switching elements operatively connected, are placed much closer to each other than in an arrangement of the switching elements, the spaced apart with each other bar members spaced apart are arranged. In the maximum nested position of the rod parts, the two switching elements take at least the overlapping position. This means that the switching elements could in principle also be moved beyond this overlapping position. The overlapping position is considered transversely to the direction of travel of the two switching elements, thus transversely to the longitudinal extent of the toggle lever tensioning device.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass das erste Schaltelement starr mit dem ersten Stangenteil verbunden ist. Diese starre Verbindung des ersten Schaltelements mit dem ersten Stangenteil ist deshalb grundsätzlich möglich und wird als vorteilhaft angesehen, weil das erste Stangenteil nicht verdrehbar ist, sondern nur das zweite Stangenteil. Es ist aber durchaus möglich, die Lagerung des ersten Schaltelements so zu gestalten, dass dieses axial festgelegt und drehbar im ersten Stangenteil gelagert ist sowie im Gehäuse des Spannkopfes geführt ist. Die Lagerung dieses ersten Schaltelementes würde somit der Lagerung des zweiten Schaltelements entsprechen.According to a preferred embodiment of the invention, it is provided that the first switching element is rigidly connected to the first rod part. This rigid connection of the first switching element with the first rod part is therefore fundamentally possible and is considered advantageous because the first rod part is not rotatable, but only the second rod part. But it is quite possible to make the storage of the first switching element so that it is axially fixed and rotatably mounted in the first rod part and guided in the housing of the clamping head. The storage of this first switching element would thus correspond to the storage of the second switching element.
Gemäß einer bevorzugten Gestaltung ist vorgesehen, dass eines der beiden Schaltelemente im wesentlichen plattenförmig und das andere Schaltelement im wesentlichen U-förmig ausgebildet ist, derart, dass bei maximal ineinandergeschraubten Stangenteilen das plattenförmige Schaltelement in das U-förmig gestaltete Schaltelement eingefahren ist. Der Freiraum zwischen den beiden Schenkeln des U ist demzufolge geeignet, das im wesentlichen plattenförmige Schaltelement aufzunehmen. Dieses kann, je nach Ausdehnung der Platte in Richtung der Längsrichtung der Stange, bei maximal ineinandergeschraubten Stangenteilen die überlappende Stellung mit dem U des anderen Schaltelements einnehmen oder sogar eine Stellung einnehmen, in der das U-förmig gestaltete Schaltelement vom plattenförmigen Schaltelement überfahren worden ist. Das jeweilige Schaltelement ist insbesondere als Fahne ausgebildet.According to a preferred embodiment, it is provided that one of the two switching elements substantially plate-shaped and the other switching element is formed substantially U-shaped, such that at maximum nested rod parts, the plate-shaped switching element is retracted into the U-shaped switching element. The space between the two legs of the U is therefore suitable to receive the substantially plate-shaped switching element. This can, depending on the extent of the plate in the direction of the longitudinal direction of the rod, take the overlapping position with maximally nested rod parts overlapping position with the U of the other switching element or even occupy a position in which the U-shaped switching element has been run over by the plate-shaped switching element. The respective switching element is designed in particular as a flag.
Die jeweilige Abfrageeinrichtung kann auf unterschiedliche Art und Weise gestaltet werden sein, insbesondere unter dem Aspekt deren Wirkprinzip. So weist beispielsweise die jeweilige Abfrageeinrichtung einen mittels des jeweiligen Schaltelements schwenkbaren oder kippbaren Schalter auf, vorzugsweise einen Endschalter, insbesondere einen pneumatischen Endschalter. Eine alternative, vorteilhafte Gestaltung sieht vor, dass die jeweilige Abfrageeinrichtung einen mittels des jeweiligen Schaltelements betätigbaren elektronischen Endschalter oder optischen Leser aufweist.The respective interrogator can be designed in different ways, especially under the aspect of their mode of action. For example, the respective interrogation device has a switch which can be swiveled or tilted by means of the respective switching element, preferably a limit switch, in particular a pneumatic limit switch. An alternative advantageous embodiment provides that the respective interrogator has an actuatable by the respective switching element electronic limit switch or optical reader.
Vorzugsweise dient die erste Abfrageeinrichtung dem Erfassen der Spannstellung des Spannarms und die zweite Abfrageeinrichtung dem Erfassen der Lösestellung des Spannarms.Preferably, the first interrogator is used to detect the clamping position of the clamping arm and the second interrogator detecting the release position of the clamping arm.
Die beiden Stangenteile können unterschiedlich gestaltet sein; es ist nur erforderlich, dass das erste Stangenteil den Abschnitt mit dem Außengewinde und das zweite Stangenteil den Abschnitt mit dem Innengewinde aufweist. Unter diesem Aspekt wird es als vorteilhaft angesehen, wenn das erste Stangenteil einen Gewindebolzen und eine Gabel aufweist. Insbesondere ist der Gewindebolzen schwenkbar mit der Gabel verbunden. Die Gabel ist vorzugsweise in Längsrichtung der Kniehebelspannvorrichtung geführt und nimmt im Bereich ihres dem Gewindebolzen abgewandten Endes schwenkbar die Kniehebelanordnung auf. Bei einer derartigen Ausbildung ist insbesondere vorgesehen, dass die Gabel das erste Schaltelement aufnimmt. Das zweite Stangenteil und das Stellteil des Antriebs bilden beispielsweise eine Baueinheit oder es ist das zweite Stangenteil axial festgelegt und hierbei drehbar oder nicht drehbar im Stellteil des Antriebs gelagert.The two rod parts can be designed differently; it is only necessary that the first rod part has the section with the external thread and the second rod part has the section with the internal thread. In this aspect, it is considered advantageous if the first rod part has a threaded bolt and a fork. In particular, the threaded bolt is pivotally connected to the fork. The fork is preferably guided in the longitudinal direction of the toggle lever clamping device and takes in the region of its end facing away from the threaded bolt pivotally the toggle lever assembly on. In such a design is provided in particular that the fork receives the first switching element. The second rod part and the actuating part of the drive form, for example, a structural unit or the second rod part is fixed axially and in this case mounted rotatably or non-rotatably in the actuating part of the drive.

Die in den Figuren gezeigten Ausführungsformen der Kniehebelspannvorrichtung 1 finden insbesondere im Karosseriebau der Kraftfahrzeugindustrie Verwendung. Die Kniehebelspannvorrichtung 1 weist einen Spannkopf 2 und einen im Spannkopf schwenkbar gelagerten Spannarm 3 auf. Dieser ist mit einer Welle 4 drehfest verbunden, die im Gehäuse 5 des Spannkopfes 2 gelagert und aus dem Gehäuse 5 heraus geführt ist.The embodiments of the toggle
Mit dem Spannkopf 2 ist ein Antrieb 6 verbunden. Dieser weist eine axial hin und her verstellbare Stange 7 auf. Eine Kniehebelanordnung 8 verbindet die Stange 7 mit der Welle 4 und damit dem Spannarm 3. Die Kniehebelanordnung weist einen Hebel 9 und einen Hebel 10 auf. Der Hebel 9 ist mit seinem einen Ende drehfest mit der Welle 4 verbunden und es ist am andere Ende des Hebels 9 der Hebel 10 mittels einer Achse 11 schwenkbar angelenkt. Das andere Ende des Hebels 10 ist mittels einer Achse 12 schwenkbar mit einer Gabel 13 der Stange 7 angelenkt. Diese Gabel 13 ist in Längserstreckung der Kniehebelspannvorrichtung 1 im Gehäuse 5 des Spannkopfes 2 axial geführt. Mit dem der Kniehebelanordnung 8 abgewandten Ende der Gabel 13 ist ein gleichfalls Bestandteil der Stange 7 bildender Gewindebolzen 14 mittels einer Achse 15, somit schwenkbar verbunden. Funktionell bilden die Gabel 13 und der Gewindebolzen 14 ein erstes Stangenteil. Der Gewindebolzen 14 ist in eine Gewindehülse 16 eingeschraubt, die mit einem in diese eingesteckten Zapfen 17 fest verbunden ist. Funktionell bilden die Gewindehülse 16 und der Zapfen 17 ein zweites Stangenteil. Der Zapfen 17 ist fest mit einem als Kolben 18 ausgebildeten, linear verstellbaren Stellteil des Antriebs 6 verbunden. Dieser Kolben 18 ist radial zum Gehäuse 19 des Antriebs 6 abgedichtet. Der mit dem Spannkopf 2 verbundene Deckel 20 des Gehäuses 19 sowie der Boden 21 des Gehäuses 19 sind mit Anschlüssen 22 für Druckluftzufuhr und Druckluftabfuhr versehen, so dass bei entsprechender Regelung der Kolben 18 zwecks Verstellbarkeit der Stange 7 hin und her verfahren werden kann.With the
Die Veränderung der Länge der Stange 7 erfolgt durch Drehen von Zapfen 17 und Gewindehülse 16 relativ zum drehfest angeordneten Gewindebolzen 14. Hierzu weist der Boden 21 auf seiner dem Spannkopf 2 abgewandten Seite eine Öffnung 23 auf, durch die der Zapfen 17 und damit die Gewindehülse 16 mittels eines Außensechskantwerkzeuges drehbar ist. Konkret ist bei in die Endposition gegen den Boden 21 verfahrenem Kolben 18 ein in der Öffnung 23 verschieblich gelagertes Stellteil 24 mit einem Vorsprung 25, der als Außensechskant ausgebildet ist, in eine Ausnehmung 26, die als Innensechskant ausgebildet ist, einfahrbar, wobei das Stellteil auf seinem der Stange 7 abgewandten Ende eine Ausnehmung 27, die einen Innensechskant aufweist, zur Aufnahme des nicht dargestellten Werkzeuges. Über das Werkzeug wird damit die Drehbewegung in das Stellteil 24 eingeleitet und aufgrund des Formschlusses zwischen Stellteil 24 und Zapfen 17 in dieser Position das Drehmoment in den Zapfen 17 und die Gewindehülse 16 eingeleitet. Beim Verfahren des Kolbens 18 von dem Boden 21 weg gelangt der Zapfen 17 außer Eingriff mit dem Stellteil 24. Ein Zurückfahren des Stellteils 24 erfolgt beispielsweise, in nicht gezeigter Art und Weise, durch Beaufschlagung des Stellteils 24 auf seiner dem Zapfen 17 zugewandten Seite mit Druckluft.The change in the length of the
Der Spannkopf 2 ist mit einer Abfrageeinheit 28 versehen, die ihrerseits eine erste Abfrageeinrichtung 29 zur Erfassung der Klemmposition des Spannarms 3, der ein Werkstück klemmt und eine zweie Abfrageeinrichtung 30 zur Erfassung der anderen geöffneten Endstellung des Spannarms 3 aufweist. Mit der ersten Abfrageeinrichtung 29 wirkt in der Klemmposition des Spannarms 3 ein erstes Schaltelement 31 zusammen, das auf der der Abfrageeinrichtung 29 zugewandten Seite fest mit dem ersten Stangenteil, konkret der Gabel 13 verbunden ist. Mit der zweite Abfrageeinrichtung 30 wirkt ein zweites Schaltelement 32 in der Offnungsendstellung des Spannarms 3 zusammen. Dieses Schaltelement 32, das gleichfalls in Richtung der Abfrageeinheit 28 orientiert ist, weist einen in Achsrichtung der Stange 7 zum Boden 31 hin gerichteten Ansatz 33 auf sowie einen mit dem Ansatz 33 verbundenen Ringabschnitt 34. Dieser ist im Bereich des der Kniehebelanordnung 8 zugewandten Endes der Gewindehülse 16 axial festgelegt, aber frei drehbar in der.Gewindehülse 16 gelagert. Um zu gewährleisten, dass das zweite Schaltelement 32 sich nicht bezüglich des Gehäuses 5 des Spannkopfes 2 verdrehen kann, weist das Gehäuse 5 ebene Führungen für den Ansatz 33 des zweiten Schaltelements 32 auf. Beim Verändern der Länge der Stange 7 bewegt sich das Schaltelement 32 somit ausschließlich linear auf das Schaltelement 31 zu oder von diesem weg.The clamping
Weist die Stange 7 eine minimale Länge auf, ist demnach der Gewindebolzen 14 vollständig in die Gewindehülse 16 eingeschraubt, nimmt bei den gezeigten Ausführungsbeispielen, wie den
Nachfolgend wird auf die unterschiedlichen Details der beiden Ausführungsformen eingegangen:The different details of the two embodiments are explained below:
Bei der Ausführungsform nach den
Damit die beiden Schaltelemente 31 und 32 die überlappende Position einnehmen können bzw. bei entsprechender konstruktiver Gestaltung grundsätzlich auch über diese Position hinaus verfahren werden könnten, ist das erste Schaltteil 31 im wesentlichen plattenförmig ausgebildet, wobei die Platte in der Querschnittsebene A-A gemäß
Die
Diese Stellung entspricht der Öffnungsposition des Spannarms 3.This position corresponds to the opening position of the clamping arm. 3
Bei Beaufschlagen des Anschlusses 22 im Boden 21 mit Druckluft und Abführen von Druckluft aus dem Deckel 20 über den dortigen Anschluss 22 wird der Kolben 18 in Richtung des Spannkopfes 2 bewegt und es gelangt das zweite Schaltelement 32 außer Kontakt mit der zweiten Abfrageeinrichtung 30. Die Endstellung des Kolbens 18, die aufgrund der gewählten Länge der Stange 7 eine im wesentlichen mittlere Stellung des Kolbens 18 im Gehäuse 19 darstellt, ergibt sich bei Kontaktierung der Rolle 36 der ersten Abfrageeinrichtung 29 durch das erste Schaltelement 31, wie es in den
Die
Bei relativ kurzem Hub des Kolbens 18 ist bei der Kniehebelspannvorrichtung eine stufenlose Öffnungswinkeleinstellung von 0° bis 135° möglich.With a relatively short stroke of the
