Description

Die Erfindung betrifft eine Spannvorrichtung zum Spannen eines Werkstücks nach dem Oberbegriff von Anspruch 1.The invention relates to a clamping device for clamping a workpiece according to the preamble of claim 1.

Bei der Montage von Werkstücken, die große Abmessungen und/oder mehrere Einzelkomponenten aufweisen, ist die Halterung des Werkstücks während der Montage von großer Bedeutung. Eine entsprechende Haltevorrichtung muss daher in erster Linie zwei Kriterien erfüllen: Sie muss einerseits eine größtmögliche Justage-Freiheit der gehalterten Elemente bieten und andererseits eine einmal eingenommene Position sicher beibehalten.When assembling workpieces that have large dimensions and/or several individual components, the support of the workpiece during assembly is of great importance. A corresponding holding device must therefore primarily meet two criteria: On the one hand, it must offer the greatest possible freedom of adjustment of the elements held and, on the other hand, it must securely maintain a position once it has been assumed.

Um ein Werkstück mit möglichst großer Freiheit im Raum positionieren zu können, sollte das Werkstück möglichst in allen Richtungen verschieb- und rotierbar sein. Die eingestellte Position sollte dann im weiteren Verlauf der Montage beibehalten werden. Insbesondere dann, wenn mehrere Komponenten zu montieren sind, ist die korrekte Positionierung und Ausrichtung der Komponenten zueinander während des Montagevorgangs notwendig.In order to be able to position a workpiece with the greatest possible freedom in space, the workpiece should be able to be displaced and rotated in all directions. The set position should then be retained in the further course of assembly. In particular when several components are to be assembled, the correct positioning and alignment of the components to one another during the assembly process is necessary.

Gängige Spannvorrichtungen besitzen maulartige Klemmbacken, zwischen denen ein Werkstück eingespannt werden kann. Eine derartige Spannvorrichtung ist wenig flexibel. Darüber hinaus sind Hilfskonstruktionen in Form von Gestellen oder Unterstützungen bekannt, wie sie beispielsweise bei der Montage von Treppengeländern verwendet werden. Diese Unterstützungen weisen säulenartige, teleskopartig höhenverstellbare Montagehilfen auf, an denen ein Werkstück, beispielsweise ein Treppensegment, angebracht werden kann. Am Montage-Ort kann das Werkstück mittels der höhenverstellbaren Montagehilfe justiert werden. Die Justage kann dabei nur entlang einer Achse der Verschiebung erfolgen. Ist die gewünschte Position erreicht, wird die Montagehilfe fixiert und die Justierung der übrigen Werkstücke bzw. Treppensegmente vorgenommen. Nach Ausrichtung und Montage aller Werkstücke sind dann die Montagehilfen abzunehmen. Gleichartige Anwendungen treten in vielen Bereichen der Industrie, beispielsweise im Fahrzeugbau, im Bereich der Handhabungs- und Montagetechnik und auch im Handwerk auf.Common clamping devices have jaw-like clamping jaws between which a workpiece can be clamped. Such a clamping device is not very flexible. In addition, auxiliary constructions in the form of frames or supports are known, such as those used in the assembly of banisters. These supports have column-like, telescopically height-adjustable assembly aids to which a workpiece, for example a stair segment, can be attached. The workpiece can be adjusted at the assembly site using the height-adjustable assembly aid. The adjustment can only be made along one axis of displacement. When the desired position is reached, the assembly aid is fixed and the remaining workpieces or stair segments are adjusted. After aligning and assembling all workpieces, the assembly aids must be removed. Similar applications occur in many areas of industry, for example in vehicle construction, in the area of handling and assembly technology and also in trade.

Die US 5 141 211 A offenbart eine Spannvorrichtung zum Halten und Aufbewahren von Werkzeugen nach dem Oberbegriff von Anspruch 1. Auf einem mit Rollen versehenen Untergestell ist ein vertikaler Pfosten befestigt, der als hohles Vierkantprofil ausgestaltet ist, das entlang einer seiner Seitenflächen mit Löchern in linearer Anordnung versehen ist. Auf dem Pfosten ist ein U-förmiges Koppelteil aufsetzbar, dass an dem Pfosten angebracht werden kann. Das Koppelteil weist ein Werkzeugträgerteil mit einem rohrförmigen Stutzen auf, in den eine Lagerplatte eingesetzt werden kann.the U.S. 5,141,211A discloses a jig for holding and storing tools according to the preamble of claim 1. Mounted on a wheeled base is a vertical post which is in the form of a hollow square section having holes in a linear array along one of its side faces. A U-shaped coupling part that can be attached to the post can be placed on the post. The coupling part has a tool carrier part with a tubular socket into which a bearing plate can be inserted.

Diese Unterstützungen weisen den Nachteil auf, dass die eingespannten Werkstücke nicht frei im Raum positionierbar sind. Die gängigen Ausführungen erlauben lediglich eine Justage in einer Verschiebungsachse. Insbesondere ermöglichen die gängigen Ausführungen keine Rotation und keine zuverlässig reproduzierbare Positionierung der Werkstücke. Es können auf diese Art nur einfache Gesamtkonstruktionen justiert und montiert werden.These supports have the disadvantage that the clamped workpieces cannot be positioned freely in space are. The current designs only allow an adjustment in one displacement axis. In particular, the current designs do not allow any rotation and no reliably reproducible positioning of the workpieces. Only simple overall constructions can be adjusted and assembled in this way.

Es ist daher die Aufgabe der Erfindung, eine gattungsgemäße Spannvorrichtung zu schaffen, die die oben angeführten Nachteile beseitigt und eine möglichst freie Ausrichtung der eingespannten Werkstücke im Raum samt Arretierung in reproduzierbarer Weise ermöglicht.It is therefore the object of the invention to provide a generic clamping device which eliminates the above-mentioned disadvantages and enables the clamped workpieces to be aligned as freely as possible in space, including locking, in a reproducible manner.

Diese Aufgabe wird mit einer Spannvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die Spannvorrichtung weist mindestens ein Säulenelement, mindestens eine Manschette, die das Säulenelement umgreift, relativ zu diesem verstellbar ist und die mindestens einen Ansatz besitzt, und mindestens einen Arm auf, der am Ansatz gehalten und relativ zu diesem verstellbar ist. Das Werkstück ist am Arm lösbar anbringbar und das Säulenelement ist mit Vertiefungen versehen. Die Manschette weist zumindest ein Befestigungselement auf, das wahlweise mit einer der Vertiefungen formschlüssig in Eingriff bringbar ist. Der Arm ist mit Vertiefungen versehen und der Ansatz weist zumindest ein Befestigungselement auf, das wahlweise mit einer der Vertiefungen formschlüssig in Eingriff bringbar ist. Erfindungsgemäß ist vorgesehen, dass die Manschette in Längsrichtung des Säulenelements verschiebbar und um dessen Achse drehbar gelagert ist.This object is achieved with a clamping device having the features of claim 1. The tensioning device includes at least one column member, at least one collar that engages the column member and is adjustable relative thereto and that has at least one lug, and at least one arm that is supported on the lug and is adjustable relative thereto. The workpiece is detachably attachable to the arm and the column member is provided with indentations. The sleeve has at least one fastening element which can be selectively positively engaged with one of the indentations. The arm is indented and the lug includes at least one fastener selectively engageable with one of the indentations. According to the invention, it is provided that the sleeve is mounted so that it can be displaced in the longitudinal direction of the column element and can be rotated about its axis.

Durch die Vertiefungen an dem Säulenelement und/oder dem Arm ist es möglich, das Werkstück am Arm der Spannvorrichtung frei im Raum zu positionieren. An ihrer gewünschten Position lassen sich die beweglichen Komponenten der Spannvorrichtung durch die Befestigungselemente arretieren, so dass die Werkstücke ihre Position im Raum beibehalten und gegebenenfalls mit der Justage der übrigen Werkstücke fortgefahren werden kann.The indentations on the column element and/or the arm make it possible to hold the workpiece on the arm of the clamping device to be positioned freely in space. The movable components of the clamping device can be locked in their desired position by the fastening elements, so that the workpieces can maintain their position in space and, if necessary, the adjustment of the other workpieces can continue.

Ein über den Ansatz und den Arm angebrachtes Werkstück kann damit in diesen Freiheitsgraden ausgerichtet werden. Auf der einmal gefundenen Position der Manschette sorgt der formschlüssige Eingriff der Befestigungselemente in den Vertiefungen des Säulenelements dafür, dass die Position der Manschette während des gesamten Montageprozesses beibehalten wird.A workpiece attached via the boss and the arm can thus be aligned in these degrees of freedom. Once the position of the sleeve has been found, the form-fitting engagement of the fastening elements in the recesses of the column element ensures that the position of the sleeve is maintained throughout the assembly process.

Zusätzlich oder alternativ dazu kann der Arm relativ zum Ansatz entlang seiner Längsachse verschieblich und um diese rotierbar ausgestattet sein. Das am Arm angebrachte Werkstück ist in diesen Freiheitsgraden somit beweglich. Der formschlüssige Eingriff der Befestigungselemente des Ansatzes in die Vertiefungen des Arms ermöglicht die Arretierung auf der eingestellten Position.In addition or as an alternative to this, the arm can be designed to be displaceable along its longitudinal axis relative to the attachment and rotatable about it. The workpiece attached to the arm can therefore be moved in these degrees of freedom. The positive engagement of the fasteners of the extension in the indentations of the arm allows it to be locked in the adjusted position.

Die Manschette kann durch formschlüssigen Eingriff mindestens zweier Befestigungselement in Vertiefungen an dem Säulenelement arretierbar sein. Alternativ oder zusätzlich dazu kann der Arm durch formschlüssigen Eingriff mindestens zweier Befestigungselemente in Vertiefungen an dem Ansatz arretierbar sein. Durch die Verwendung von mindestens zwei Befestigungselementen zur Arretierung der entsprechenden Komponenten wird eine auch unter statischer Gewichtsbelastung stabile Arretierung der Komponenten erzielt.The cuff can be locked in recesses on the column element by form-fitting engagement of at least two fastening elements. As an alternative or in addition to this, the arm can be locked in recesses on the attachment by positive engagement of at least two fastening elements. By using at least two fastening elements for locking the corresponding components, a stable locking of the components is achieved even under static weight loading.

Vorzugsweise sind die Vertiefungen als Mulden oder Löcher ausgebildet. Auf diese Weise sind die Vertiefungen einfach herstellbar. Der formschlüssige Eingriff der Befestigungselemente in Mulden oder Löcher ist darüber hinaus einfach zu realisieren und garantiert einen sicheren Halt der Komponenten während der Montage.The indentations are preferably in the form of troughs or holes. In this way, the depressions are easy to produce. The form-fitting engagement of the fasteners in recesses or holes is also easy to implement and guarantees that the components are held securely during assembly.

Die Vertiefungen können sich mindestens abschnittsweise in Längs- und/oder Umfangsrichtung des Säulenelements und/oder des Armes erstrecken. Dabei bedeutet ein größerer, mit Vertiefungen versehener Bereich einen vergrößerten Einstellbereich bei der Justage des Werkstücks.The depressions can extend at least in sections in the longitudinal and/or circumferential direction of the column element and/or the arm. A larger area provided with indentations means an enlarged adjustment range when adjusting the workpiece.

Die Vertiefungen können in einer rasterförmigen Anordnung vorliegen. Sie können beispielsweise in Längs- und/oder in Umfangsrichtung des Säulenelements und/oder des Arms angeordnet sein. Durch diese Art der Anordnung der Vertiefungen wird eine Anzahl von möglichen Haltepositionen der Spannvorrichtung geschaffen. Je mehr Vertiefungen vorgesehen sind, desto genauer kann die Justage des Werkstücks vorgenommen werden. Beispielsweise können Vertiefungen in mehreren Reihen entlang der Längsrichtung beispielsweise des Säulenelements vorliegen, wobei eine Reihe aus einer Anzahl an in Umfangsrichtung vorgesehenen Vertiefungen gebildet ist.The depressions can be present in a grid-like arrangement. They can be arranged, for example, in the longitudinal and/or in the circumferential direction of the column element and/or the arm. This type of arrangement of the indentations creates a number of possible holding positions for the clamping device. The more indentations are provided, the more precisely the workpiece can be adjusted. For example, indentations may be present in a plurality of rows along the longitudinal direction of, for example, the pillar member, one row being formed of a number of indentations provided in the circumferential direction.

Hierbei ist es vorteilhaft, die Vertiefungen einer Reihe in Umfangsrichtung gleich verteilt und/oder zueinander versetzt anzuordnen. In dieser Anordnung weisen jeweils zwei benachbarte Vertiefungen die gleiche Raumdifferenz bezüglich ihres gemeinsamen radialen Mittelpunktes auf. Die Position der Manschette und/oder des Arms ist somit auf mehreren, gleichmäßig verteilten Punkten arretierbar.It is advantageous here to arrange the indentations of a row evenly distributed in the circumferential direction and/or to arrange them offset from one another. In this arrangement, each two adjacent depressions have the same spatial difference with respect to their common radial center. The position of the cuff and/or the arm can thus be locked at several evenly distributed points.

Vorzugsweise ist einigen der Vertiefungen am Säulenelement und/oder am Arm eine Information auf der Oberfläche zugeordnet. Diese Information kann beispielsweise als Skala bezüglich einer Bewegung in Translation und/oder Rotation vorliegen. Die Reproduzierbarkeit des Justageergebnisses ist somit gewährleistet: Die einzelnen Positionen der beweglichen Komponenten der Schnellspannvorrichtung sind von außen leicht erkennbar und können im Falle einer Neujustage wieder schnell eingestellt werden.Information on the surface is preferably assigned to some of the depressions on the column element and/or on the arm. This information can be present, for example, as a scale relating to a movement in translation and/or rotation. The reproducibility of the adjustment result is thus guaranteed: The individual positions of the movable Components of the quick-release device are easily recognizable from the outside and can be quickly set again in the event of a readjustment.

Die Befestigungselemente können als Schrauben, Muttern oder Bolzen ausgestaltet sein. Der erfindungsgemäße formschlüssige Eingriff der Befestigungselemente in die Vertiefungen der Spannvorrichtung ist somit auf einfache Art und Weise möglich. Darüber hinaus können die Befestigungselemente mit Federn in ihre Eingriffstellung beaufschlagt werden. Hierdurch ist eine schnelle Justage und zuverlässige Arretierung der Komponenten der Spannvorrichtung auf ihrer Position gegeben.The fasteners can be designed as screws, nuts or bolts. The form-fitting engagement of the fastening elements in the depressions of the clamping device according to the invention is thus possible in a simple manner. In addition, the fasteners can be loaded with springs in their engaged position. This allows for quick adjustment and reliable locking of the components of the clamping device in their position.

Der Arm der Spannvorrichtung innerhalb des Ansatzes kann drehbar um seine Längsachse und/oder verschieblich in Richtung der Längsachse aufgenommen sein. Damit kann eine Justage des Werkstücks in radialer Richtung in Relation zum Säulenelement vorgenommen werden.The arm of the tensioner within the lug may be rotatably received about its longitudinal axis and/or slidable in the direction of the longitudinal axis. This allows the workpiece to be adjusted in the radial direction in relation to the column element.

Am Arm kann ein Halter zur Aufnahme des Werkstücks angeordnet sein. In einer möglichen Ausgestaltung besitzt der Halter ein Endstück, das am Arm anbringbar ist, und eine Halteplatte zur Aufnahme des Werkstücks. Die Justage des Werkstücks wird durch die Bewegungen der Manschette am Säulenelement und/oder der Bewegung des Arms im Ansatz vorgenommen.A holder for receiving the workpiece can be arranged on the arm.

The depressions 11 extend over the entire lateral surface of the column element 10 and are designed as holes in the exemplary embodiment shown.

Die Vertiefungen 11 des Säulenelements 10 liegen in einem äquidistanten Raster vor: In Umfangsrichtung besitzen jeweils zwei benachbarte Vertiefungen 11 die gleiche Raumwinkeldifferenz in Bezug auf ihren gemeinsamen radialen Mittelpunkt. In Längsrichtung des Säulenelements 10 besitzen jeweils zwei benachbarte Vertiefungen den gleichen Abstand zueinander.The indentations 11 of the column element 10 are present in an equidistant grid: in the circumferential direction, two adjacent indentations 11 each have the same spatial angle difference in relation to their common radial center point. In the longitudinal direction of the column element 10, two adjacent depressions are at the same distance from one another.

Das Säulenelement 10 weist sechs Manschetten 20 auf, die das Säulenelement 10 umgreifen. Die Manschetten 20 sind rohrförmige Hohlzylinder und in Richtung der Längsachse V des Säulenelements 10 verschieblich sowie um diese Längsachse drehbar, wie es durch den Pfeil angedeutet ist. Die Rotationsrichtung D steht dabei senkrecht auf der Längsachse V des Säulenelements 10.The pillar element 10 has six cuffs 20 which enclose the pillar element 10 . The collars 20 are tubular hollow cylinders and are displaceable in the direction of the longitudinal axis V of the column element 10 and rotatable about this longitudinal axis, as indicated by the arrow. The direction of rotation D is perpendicular to the longitudinal axis V of the column element 10.

Die Höhe der Manschetten 20 entlang der Längsachse V ist jeweils gleich und beträgt im dargestellten Ausführungsbeispiel in etwa die Länge von acht Vertiefungen.The height of the cuffs 20 along the longitudinal axis V is the same in each case and is approximately the length of eight depressions in the exemplary embodiment shown.

Die Manschetten 20 weisen jeweils zwei Befestigungselemente 21 auf. Die Befestigungselemente 21 sind im gezeigten Ausführungsbeispiel mit Federn beaufschlagte Bolzen, wobei die Federkraft in Richtung der radialen Mitte der Manschetten 20 wirkt. Die zwei Befestigungselemente 21 einer Manschette 20 liegen diametral punktsymmetrisch gegenüber in Bezug zu dem räumlichen Mittelpunkt der Manschette. Die Ausgestaltung der Vertiefungselemente 21 ist derart, dass die Vertiefungselemente 21 formschlüssig in die Vertiefungen 11 des Säulenelements 10 in Eingriff bringbar sind.The cuffs 20 each have two fastening elements 21 . In the exemplary embodiment shown, the fastening elements 21 are spring-loaded bolts, the spring force acting in the direction of the radial center of the sleeves 20 . The two fastening elements 21 of a cuff 20 are diametrically opposite in point symmetry in relation to the spatial center point of the cuff. The configuration of the recess elements 21 is such that the recess elements 21 can be positively engaged in the recesses 11 of the column element 10 .

Die Manschetten 20 weisen jeweils einen Ansatz 30 auf. Der Ansatz 30 ragt radial nach außen vom Säulenelement 10 hervor und ist als rohrförmiger Hohlzylinder ausgebildet. Der Querschnitt des Ansatzes 30 ist geringer als die vertikale Höhe der Manschette 20. Im Bereich des dem Säulenelement 10 abgewandten Endes des Ansatzes 30 sind zwei Befestigungselemente 21 in Form von Bolzen vorgesehen. Es sind jedoch auch Ausführungen mit Schrauben und Muttern denkbar. Die Befestigungselemente 21 des Ansatzes 30 liegen sich achsensymmetrisch gegenüber, wobei die Symmetrieachse mit der Längsachse durch die radiale Mitte des Ansatzes 30 zusammenfällt.The cuffs 20 each have an attachment 30 . The projection 30 protrudes radially outwards from the column element 10 and is designed as a tubular hollow cylinder. The cross section of the extension 30 is less than the vertical height of the collar 20. In the area of the end of the extension 30 facing away from the column element 10, two fastening elements 21 in the form of bolts are provided. However, versions with screws and nuts are also conceivable. The fasteners 21 of the approach 30 are axisymmetric opposite, wherein the axis of symmetry coincides with the longitudinal axis through the radial center of the projection 30.

In jedem Ansatz 30 ist ein stabförmiger Arm 40 eingesetzt. Der Arm 40 ist kreiszylinderförmig ausgestaltet und weist einen geringeren Durchmesser als der Innendurchmesser des Ansatzes 30 auf. Der Arm 40 ist in Längsrichtung H relativ zum Ansatz 30 beweglich und kann in Richtung S rotiert werden. Auf der Mantelfläche des Arms 40 sind Vertiefungen 11 ausgebildet, die in einem ähnlichen Raster wie die Vertiefungen 11 des Säulenelements 10 angeordnet sind. Sie sind somit über die Mantelfläche des Armes gleich verteilt. Die Dimensionierung der Befestigungselemente 21 und der Vertiefungen 11 ist derart, dass die Befestigungselemente mit den Vertiefungen 11 formschlüssig in Eingriff bringbar sind.In each approach 30 a rod-shaped arm 40 is used. The arm 40 is designed in the shape of a circular cylinder and has a smaller diameter than the inner diameter of the extension 30 . The arm 40 is movable in the longitudinal direction H relative to the extension 30 and can be rotated in the S direction. Indentations 11 are formed on the lateral surface of the arm 40 and are arranged in a grid similar to that of the indentations 11 of the column element 10 . They are thus evenly distributed over the lateral surface of the arm. The dimensioning of the fastening elements 21 and the depressions 11 is such that the fastening elements can be brought into positive engagement with the depressions 11 .

An der dem Säulenelement 10 entfernt liegenden Stirnseite der oberen zwei Arme 40 ist jeweils ein Halter 50 vorgesehen. Der Halter 50 weist ein Endstück 51, eine Halteplatte 52, ein Drehgelenk 53 sowie ein Befestigungselement 54 auf. Das Endstück 51 ist mit dem Arm 40 verbunden und erstreckt sich parallel zur Längsrichtung H des Armes 40. An dem dem Arm 40 abgewandten Ende des Endstückes 51 ist ein Drehgelenk 53 vorgesehen, über das die Halteplatte 52 mit dem Endstück 51 verbunden ist. Die Halteplatte 52 dient zum Einspannen des Werkstücks. Durch das Drehgelenk 53 ist die Halteplatte 52 und damit auch das darauf eingespannte Werkstück in einem Winkel von ca. 180° schwenkbar.A holder 50 is provided in each case on the end face of the upper two arms 40 which is remote from the column element 10 . The holder 50 has an end piece 51 , a holding plate 52 , a swivel joint 53 and a fastening element 54 . The end piece 51 is connected to the arm 40 and extends parallel to the longitudinal direction H of the arm 40 . The holding plate 52 is used to clamp the workpiece. The holding plate 52 and thus also the workpiece clamped thereon can be pivoted at an angle of approximately 180° by the swivel joint 53 .

Die unteren vier Manschetten 20 in Figur 1 zeigen eine alternative Ausgestaltung eines Halters 50. Dieser weist eine Spanneinrichtung 55 mit einer Schale 56, ein Kugelelement 57, ein Halteteil 58, mehrere Befestigungselemente 59 und Vertiefungen 60 auf.The bottom four cuffs are 20 in figure 1 show an alternative embodiment of a holder 50. This has a clamping device 55 with a shell 56, a ball element 57, a holding part 58, a plurality of fastening elements 59 and 60 recesses.

Die Schale 56 ist mit dem Arm 40 fest verbunden. Sie ist als schalenartige Halbkugel ausgebildet und innen hohl. An dem dem Arm 40 abgewandten Ende sind vier Befestigungselemente 59 angeordnet. In die Schale 56 ist ein Kugelelement 57 eingesetzt. Das Kugelelement 57 ist in der Schale 56 frei drehbar gelagert und von der Schale 56 derart umgeben, dass ein Herausfallen des Kugelelements 57 vermieden wird, wie es durch die Pfeile U angeordnet ist.The shell 56 is fixed to the arm 40 . It is designed as a shell-like hemisphere and is hollow on the inside. Four fastening elements 59 are arranged on the end facing away from the arm 40 . A ball element 57 is inserted into the shell 56 . The ball member 57 is freely rotatably supported in the shell 56 and surrounded by the shell 56 in such a manner as to prevent the ball member 57 from falling out, as indicated by the arrows U .

Auf der Oberfläche des Kugelelements 57 sind Vertiefungen 60 ausgebildet, die derart angeordnet sind , dass jeweils zwei benachbarte Vertiefungen die gleiche Raumwinkeldifferenz relativ zum Mittelpunkt des Kugelelements 57 aufweisen. An dem dem Arm 40 entfernt liegenden Ende des Kugelelements 57 ist ein Halteteil 58 angebracht, das zum Einspannen eines Werkstücks dient.Indentations 60 are formed on the surface of the spherical element 57 and are arranged in such a way that two adjacent indentations each have the same spatial angle difference relative to the center point of the spherical element 57 . Attached to the end of the ball member 57 remote from the arm 40 is a holding member 58 for clamping a workpiece.

Im Folgenden soll der Montagevorgang eines Werkstückes mit der erfindungsgemäßen Spannvorrichtung 1 beschrieben werden: Zunächst wird das Säulenelement 10 mit dem Standfuß 12 an dem Montageort platziert. Im nächsten Schritt wird eine Manschette 20 über die obere Stirnseite des Säulenelementes 10 geführt und die gewünschte Höhe sowie Drehausrichtung der Manschette 20 relativ zum Säulenelement 10 eingestellt. Ist die gewünschte Position eingenommen, werden die Befestigungselemente 21 der Manschette 20 betätigt, woraufhin diese formschlüssig in Eingriff mit den Vertiefungen 11 des Säulenelements 10 gebracht werden. Dadurch ist die Manschette 20 am Säulenelement 10 fixiert. Danach wird der Arm 40 in den Ansatz 30 der Manschette 20 eingeführt. Durch die teleskopierbare Ausgestaltung des Arms 40 und des Ansatzes 30 wird der Arm 40 auf seine gewünschte Position in Längsrichtung H in den Ansatz 30 gebracht. Gegebenenfalls kann sich daran eine Rotation des Arms 40 um seine Längsachse H in Drehrichtung S anschließen. Wenn sich der Arm 40 in seiner gewünschten Position befindet, werden die Befestigungselemente 21 des Ansatzes 30 betätigt. Diese greifen dann mit Hilfe der Federn formschlüssig in die Vertiefungen 11 des Arms 40 ein. Damit ist der Arm 40 relativ zum Ansatz 30 arretiert.The assembly process of a workpiece with the clamping device 1 according to the invention is to be described below: First, the column element 10 with the base 12 is placed at the assembly site. In the next step, a cuff 20 is guided over the upper end face of the column element 10 and the desired height and rotational orientation of the cuff 20 relative to the column element 10 are set. Once the desired position has been reached, the fastening elements 21 of the cuff 20 are actuated, whereupon they are brought into engagement with the depressions 11 of the column element 10 in a form-fitting manner. Thereby, the cuff 20 is fixed to the pillar member 10 . Thereafter, the arm 40 is inserted into the base 30 of the cuff 20. through the telescopic configuration of the arm 40 and the extension 30, the arm 40 is brought to its desired position in the longitudinal direction H in the extension 30. Optionally, this can be followed by a rotation of the arm 40 about its longitudinal axis H in the direction of rotation S. When the arm 40 is in its desired position, the fasteners 21 of the lug 30 are actuated. These then engage with the springs in a form-fitting manner in the depressions 11 of the arm 40 . The arm 40 is thus locked relative to the projection 30 .

An dem dem Säulenelement 10 entfernt liegenden Ende des Arms 40 ist ein Halter 50 angebracht. Wird ein Halter 50 gemäß der ersten Ausgestaltung verwendet, weist dieser ein Drehgelenk 53 auf. Das Werkstück wird dann auf der Halteplatte 52 eingespannt und mit Hilfe des Drehgelenks 53 justiert. Gegebenenfalls kann sich daran eine Feinjustage des Werkstücks durch Lösen der Befestigungselemente 21 von den Vertiefungen 11 anschließen.At the end of the arm 40 remote from the column member 10, a bracket 50 is attached. If a holder 50 according to the first embodiment is used, it has a swivel joint 53 . The workpiece is then clamped on the holding plate 52 and adjusted with the aid of the swivel joint 53 . If necessary, this can be followed by a fine adjustment of the workpiece by loosening the fastening elements 21 from the depressions 11 .

Wird die zweite Ausgestaltung des Halters 50 verwendet, weist der Halter 50 eine Spanneinrichtung 55 auf. Das Werkstück wird auf das Halteteil 58 der Spanneinrichtung 55 gespannt, woraufhin das Werkstück in die gewünschte Position bewegt wird. Dann werden die Befestigungselemente 59 betätigt und greifen formschlüssig in die Vertiefungen 60 des Kugelelementes 57 an. Die Schale 56 ist dabei mit dem Arm 40 fest verbunden. Auch hier kann sich gegebenenfalls eine Feinjustage anschließen, indem einzelne Befestigungselemente 21 gelöst werden und damit die betreffenden Komponenten beweglich sind.If the second embodiment of the holder 50 is used, the holder 50 has a tensioning device 55 . The workpiece is clamped onto the holding part 58 of the clamping device 55, after which the workpiece is moved to the desired position. The fastening elements 59 are then actuated and engage in the depressions 60 of the ball element 57 in a form-fitting manner. The shell 56 is firmly connected to the arm 40 . Here, too, a fine adjustment can follow if necessary, in that individual fastening elements 21 are loosened and the relevant components are thus movable.

In der gewünschten Position des Werkstücks werden dann alle Befestigungselemente 21 betätigt. Das Werkstück ist somit im Raum justiert und auf seiner Position arretiert. Damit ist die Justage eines Werkstücks abgeschlossen.All fastening elements 21 are then actuated in the desired position of the workpiece. The workpiece is thus adjusted in space and locked in its position. This completes the adjustment of a workpiece.

Bei der Montage mehrerer Werkstücke sind wahlweise mehrere Manschetten 20 mit Ansätzen 30, Armen 40 und Haltern 50 zu verwenden, oder es kann auf ein weiteres Säulenelement 10 zurückgegriffen werden.When assembling a number of workpieces, a number of sleeves 20 with attachments 30, arms 40 and holders 50 can optionally be used, or an additional column element 10 can be used.
