Der Erfindung liegt die Aufgabe zugrunde, eine rein mechanisch wirkende Spannvorrichtung für Bauteile bereit zu stellen, die einfach in der Handhabung und für eine Vielzahl technischer Einsatzbereiche einsetzbar sein soll.The invention has for its object to provide a purely mechanically acting clamping device for components that should be easy to use and for a variety of technical applications.

Diese Aufgabe wird gelöst durch eine mechanisch wirkende Spannvorrichtung für Bauteile, zumindest beinhaltend einen Grundkörper, der im Bereich seines einen Endes mittel- oder unmittelbar mit einem ersten Spannelement in Wirkverbindung steht und der im Bereich seines anderen Endes mittel- oder unmittelbar einen einseitig gelagerten Schwenkarm aufnimmt, dessen einer Endbereich ein zweites Spannelement trägt und dessen anderer Endbereich nach dem Aufnehmen und Spannen des Bauteiles über ein Verriegelungselement relativ zum Grundkörper festgelegbar ist.This object is achieved by a mechanically acting clamping device for components, at least comprising a base body which is in the region of one end medium or directly with a first clamping element in operative connection and medium or directly in the region of its other end receives a cantilever mounted swivel arm whose one end region carries a second tensioning element and whose other end region can be fixed relative to the base body after picking up and tensioning the component via a locking element.

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous developments of the subject invention can be found in the dependent claims.

Mit dem Erfindungsgegenstand wird somit eine rein mechanisch wirkende Spannvorrichtung für Bauteile vorgestellt, die beispielsweise in der Automobilindustrie eingesetzt werden kann. Ebenfalls denkbar wären Einsatzfälle in der Verpackungsmittelindustrie, die einen geringen Automatisierungsgrad und einfach zu transportierende Teile aufweist.With the subject invention, a purely mechanically acting clamping device for components is thus presented, which can be used for example in the automotive industry. Also conceivable applications would be in the packaging industry, which has a low degree of automation and easy to transport parts.

Im Stand der Technik werden Spannvorrichtungen beschrieben, die alternative Spannmittel aufweisen. Hier werden bedarfsweise weitere Energiequellen, wie z. B. Strom, Druckluft, Hydraulikmedium oder dergleichen eingesetzt, um die entsprechenden Spannkräfte realisieren zu können. Derartige zusätzliche Energiequellen sind bei der erfindungsgemäßen rein mechanisch wirkenden Spannvorrichtung entbehrlich, so dass nicht nur ein einfacher Aufbau, sondern darüber hinaus auch ein preiswertes Umfeld gegeben ist. Die rein mechanisch wirkende Spannvorrichtung kann beispielsweise an einem Roboterarm vorgesehen werden, der Bauteile aus einer Aufnahmestation, beispielsweise in den Bereich einer Bearbeitungs- oder Abgabestation, überführt.In the prior art clamping devices are described which have alternative clamping means. Here, if necessary, further energy sources, such. As electricity, compressed air, hydraulic medium or the like used to realize the corresponding clamping forces can. Such additional energy sources are dispensable in the purely mechanically acting clamping device according to the invention, so that not only a simple structure, but also an inexpensive environment is given. The purely mechanically acting clamping device can be provided, for example, on a robot arm, which transfers components from a receiving station, for example into the region of a processing or dispensing station.

In der jeweiligen Aufnahme- oder Abgabestation sind Hilfsmittel vorgesehen, über welche Bauteile der erfindungsgemäßen Spannvorrichtung verriegel- oder entriegelbar sind. Auch selbige sind von ihrer Funktion her rein mechanisch aufgebaut.Auxiliaries are provided in the respective receiving or dispensing station over which components of the clamping device according to the invention are locked or locked can be unlocked. Also these are purely mechanically constructed by their function.

Die wesentlichen Bauteile der erfindungsgemäßen Spannvorrichtung bestehen somit aus einem etwa L- oder U-förmigen Grundkörper, der mittel- oder unmittelbar mit einem einseitig gelagerten Schwenkarm in Verbindung steht, wobei der Schwenkarm über ein Verriegelungselement für Transportzwecke relativ zum Grundkörper festlegbar ist. Zur Vermeidung von Geräuschen beim Ver- bzw. Entriegeln der Bauteile kommen elastische Federelemente zum Einsatz. Sowohl der Grundkörper als auch der Spannarm verfügen in ihren einander zugewandten Enden über erste und zweite Spannelemente, die das Bauteil zwischen sich aufnehmen. Das Verriegelungselement ist am den Spannelementen abgewandten Ende des Grundkörpers vorgesehen.The essential components of the clamping device according to the invention thus consist of an approximately L- or U-shaped base body, which is directly or indirectly connected to a cantilevered arm in connection, wherein the pivot arm is fixed relative to the base body via a locking element for transport purposes. To avoid noise when locking or unlocking the components elastic spring elements are used. Both the main body and the clamping arm have in their ends facing each other via first and second clamping elements which receive the component between them. The locking element is provided on the clamping elements facing away from the end of the body.

Figur 1 zeigt eine Einzelteilübersicht der erfindungsgemäßen rein mechanisch wirkenden Spannvorrichtung 1 für Bauteile 2, beispielsweise ein Blech. Die Vorrichtung 1 besteht aus einem etwa L-förmigen Grundkörper 3, der einen dünneren Schenkel 4 und einen dickeren Schenkel 5 beinhaltet. Über ein Shimspaket 6 ist der dünnere Schenkel 4 des Grundkörpers 3 mit einem im Querschnitt L-förmigen Konturstück 7 verbunden, das im Bereich seines außerhalb des Schenkels 4 vorgesehenen Endes 8 in ein erstes Spannelement 9 ausläuft. Am dickeren Schenkel 5 des Grundkörpers 3 sind zwei unter einem Winkel verlaufende plattenartige Bauelemente 10, 11 vorgesehen, die zur einseitigen Verlagerung eines Schwenkarmes 12 über einen Bolzen 13 miteinander verbunden sind. Der Schwenkarm 12 wird somit zwischen den plattenförmigen Bauelementen 10, 11 gehalten und ist um die Bolzenachse 13' des Bolzens 13 in Pfeilrichtung schwenkbar. Dies wird in den weiteren Figuren näher erläutert. Der Schwenkarm 12 trägt in seinem einen Endbereich 14 ein weiteres elastisches Spannelement 15 und wirkt in seinem anderen Endbereich 16 im verriegelten Zustand der Spannvorrichtung 1 mit einem Verriegelungselement 17 zusammen. In Figur 1 dargestellt ist der verriegelte Zustand der Spannvorrichtung 1. Das Verriegelungselement 17 ist über Befestigungsmittel 18 relativ zum Grundkörper 3 um eine nur angedeutete Schwenkachse 19 einseitig schwenkbar gelagert. Das Verriegelungselement 17 ist im Querschnitt etwa T-förmig aufgebaut, wobei der Schenkel 20 mit dem Endbereich 16 des Spannarmes 12 in Wirkverbindung bringbar ist. FIG. 1 shows an item overview of the purely mechanically acting clamping device 1 according to the invention for components 2, for example, a metal sheet. The device 1 consists of an approximately L-shaped base body 3, the one thinner leg 4 and a thicker leg 5 includes. About a Shimspaket 6 of the thinner leg 4 of the base body 3 is connected to a cross-sectionally L-shaped contour piece 7, which expires in the region of its provided outside of the leg 4 end 8 in a first clamping element 9. At the thicker leg 5 of the base body 3, two plate-like components 10, 11 extending at an angle are provided, which are connected to each other for unilateral displacement of a pivoting arm 12 via a bolt 13. The pivot arm 12 is thus held between the plate-shaped components 10, 11 and is pivotable about the pin axis 13 'of the bolt 13 in the arrow direction. This will be explained in more detail in the other figures. The pivot arm 12 carries in its one end portion 14, a further elastic tensioning element 15 and acts in its other end portion 16 in the locked state of the tensioning device 1 with a locking element 17 together. In FIG. 1 the locked state of the tensioning device 1 is shown. The locking element 17 is pivotally mounted on one side about fixing means 18 relative to the base body 3 about a pivot axis 19 only indicated. The locking element 17 is constructed approximately T-shaped in cross section, wherein the leg 20 can be brought into operative connection with the end region 16 of the clamping arm 12.

Spannelementseitig ist am Spannarm 12 eine um eine Drehachse 21' drehbare Schließrolle 21 vorgesehen. Das dem Befestigungsmittel 18 gegenüberliegende Ende des Schenkels 23 bildet ein Öffnungsmittel 22 zum Öffnen der Spannvorrichtung 1. Auch diese Bauteile werden in den weiteren Figuren näher erläutert. Die Pfeile 24, 25 deuten Federn an, die auf den Spannarm 12 sowie das Verriegelungselement 17 einwirken.On the clamping element 12, a closing roller 21 rotatable about an axis of rotation 21 'is provided on the clamping element side. The fastening means 18 opposite end of the leg 23 forms an opening means 22 for opening the clamping device 1. These components are explained in more detail in the other figures. The arrows 24, 25 indicate springs, which act on the clamping arm 12 and the locking element 17.

Figur 2 zeigt den ersten Schritt einer Bauteilentnahme. Die Spannvorrichtung 1 ist geöffnet. In einer Bauteilentnahmestation prüft ein nicht weiter dargestellter Sensor, inwieweit die Spannvorrichtung 1 tatsächlich geöffnet ist. Mit dem Pfeil a ist die Bewegungsrichtung der Spannvorrichtung 1 angedeutet. In diesem geöffneten Zustand fährt die Spannvorrichtung 1 mit der Schließrolle 21 auf eine nur angedeutete Schikane 26 (Hilfsmittel im Bereich der Entnahmestation). Durch Abrollen der Schließrolle 21 auf der flächenförmig ausgebildeten Schikane 26 wird der Spannarm 12 um seine Schwenkachse 13' in Pfeilrichtung verschwenkt, so dass sich das zweite Spannelement 15 in Richtung des ersten Spannelementes 9 bewegt. Das Verriegelungselement 17 liegt in dieser Position mit seinem Schenkel 20 noch neben dem Ende 16 des Schwenkarmes 12. Die Ansicht A der Figur 2 zeigt die Relation zwischen dem Schenkel 20 und dem Endbereich 16 des Schwenkarmes 12. Das aufzunehmende Bauteil 2 ist in diesem Zustand zwischen den Spannelementen 9,15 positioniert. FIG. 2 shows the first step of a component removal. The clamping device 1 is open. In a component removal station, a sensor, not shown, checks to what extent the tensioning device 1 is actually opened. With the arrow a, the direction of movement of the clamping device 1 is indicated. In this When open, the tensioning device 1 moves with the closing roller 21 to an only indicated chicane 26 (auxiliary device in the region of the removal station). By rolling the closing roller 21 on the surface-shaped baffle 26 of the clamping arm 12 is pivoted about its pivot axis 13 'in the arrow direction, so that the second clamping element 15 moves in the direction of the first clamping element 9. The locking element 17 is in this position with his leg 20 still near the end 16 of the pivot arm 12. The view A of FIG. 2 shows the relation between the leg 20 and the end portion 16 of the pivot arm 12. The male component 2 is positioned in this state between the clamping elements 9,15.

Figur 3 zeigt die Position der Spannarmverriegelung. Die Schließrolle 21 ist nun am Ende der Schikane 26 angelangt, so dass das Bauteil 2 zwischen den Spannelementen 9,15 erfasst ist. Im geschlossenen Zustand der Spannelemente 9,15 schließt das Verriegelungselement 17 mit Hilfe einer Feder 25 und ruht mit seinem Schenkel 20 dann auf dem Endbereich 16 des Spannarmes 12. Der Spannarm 12 ist in dieser Position relativ zum Grundkörper 3 festgelegt und das Bauteil 2 fest zwischen den Spannelementen 9,15 eingespannt. Wie dem Detailbild zu entnehmen ist, verfügt der Schenkel 20 über einen ausgeformten Bereich 27 (Rechteckausschnitt), der nach Abschluss der Bauteilaufnahme auf dem Endbereich 16 des Spannarmes 12 unter Einwirkung der Federkraft 25 aufliegt. FIG. 3 shows the position of the tensioner arm lock. The closing roller 21 has now reached the end of the baffle 26, so that the component 2 between the clamping elements 9,15 is detected. In the closed state of the clamping elements 9,15 closes the locking element 17 by means of a spring 25 and rests with its legs 20 then on the end portion 16 of the clamping arm 12. The clamping arm 12 is fixed in this position relative to the base body 3 and the component 2 fixed between clamped the clamping elements 9,15. As can be seen from the detail image, the leg 20 has a shaped area 27 (rectangular cut-out), which rests on the end area 16 of the tensioning arm 12 under the action of the spring force 25 after completion of the component reception.

Figur 4 zeigt den Bauteiltransport. Erkennbar ist noch die vorzugsweise stationär angeordnete Schikane 26. Das Bauteil 2 wird nach wie vor sicher zwischen den Spannelementen 9,15 gehalten, da der Spannarm 12 relativ zum Grundkörper 3 über das Verriegelungselement 17 festgelegt ist. Der Transport erfolgt zunächst in Pfeilrichtung b. FIG. 4 shows the component transport. Visible is still preferably arranged stationary chicane 26. The component 2 is still held securely between the clamping elements 9,15, since the clamping arm 12 is fixed relative to the base body 3 via the locking element 17. The transport takes place initially in the direction of arrow b.

Figur 5 zeigt den Beginn der Bauteilablage. Die Spannvorrichtung 1 fährt mit gespanntem Bauteil 2 auf eine in einer nicht weiter dargestellten Ablagestation vorgesehene Ablageschikane 28 (Hilfsmittel), die mit dem Öffnungsmittel 22 des Verriegelungselementes 17 in Wirkverbindung gebracht wird. Durch Einbringen der Spannvorrichtung in Pfeilrichtung c in den Bereich der Ablagestation und Auflage des Öffnungsmittels 22 auf der Ablageschikane 28 wird der Schenkel 20 des Verriegelungselementes 17 um die Schwenkachse 19 in Pfeilrichtung bewegt und gibt das Ende 16 des Schwenkarmes 12 frei. Selbiger kann nun um die Schwenkachse 13' bewegt werden, so dass das Spannelement 15 vom Spannelement 9 wegbewegbar ist und das Bauteil 2 wieder freigegeben wird. FIG. 5 shows the beginning of component storage. The tensioning device 1 moves with the clamped component 2 to a storage chute 28 (auxiliary means) provided in a storage station, not shown, which is brought into operative connection with the opening means 22 of the locking element 17. By introducing the Clamping device in the direction of arrow c in the area of the storage station and support of the opening means 22 on the tray baffle 28, the leg 20 of the locking member 17 is moved about the pivot axis 19 in the arrow direction and releases the end 16 of the pivot arm 12 free. The same can now be moved about the pivot axis 13 ', so that the clamping element 15 can be moved away from the clamping element 9 and the component 2 is released again.

Figur 6 zeigt eine Position, wie sie etwa in Figur 2 dargestellt ist. Der Schwenkarm 12 befindet sich in seiner geöffneten Position und wird durch die Feder 24 relativ zum Grundkörper 3 bewegt. Der Schenkel 20 des Verriegelungselementes 17 liegt nunmehr wieder neben dem Endbereich 16 des Spannarmes 12. In diesem Zustand prüft ein weiterer nicht dargestellter Sensor, ob die Spannvorrichtung geöffnet ist. FIG. 6 shows a position such as in FIG. 2 is shown. The pivot arm 12 is in its open position and is moved by the spring 24 relative to the base body 3.
