Description

Die Erfindung betrifft eine Tragplatte mit Spannvorrichtung gemäss Oberbegriff des Hauptanspruches. Eine Spannvorrichtung, die die Merkmale des Oberbegriffs des Hauptanspruches aufweist, ist bereits aus dem Dokument DD-A 135455 bekannt. Der weitere diesbezügliche einschlägige Stand der Technik wird bspw. durch folgende Druckschriften repräsentiert: DE-U 7 806 055, GB-A 778 865, US-A 3 480 271 und US-A 2 436 941. Solche Spannvorrichtungen werden bspw. an Werkstücksauflageplatten od. dgl. an- oder aufgesetzt befestigt, wobei der Spannhebel in Schliessstellung das betreffende Werkstück (bspw. Karosserie oder Karosserieteil) gegen die Auflageplatte drückt und festgespannt hält. Dies bedeutet, dass die Auflageplatte rings um die Kontur des betreffenden Werkstückes mit Spannvorrichtungen besetzt ist. Durch moderne Fertigungsmethoden, insbesondere in der Autoindustrie, ist die Forderung entstanden, die im Zuge einer Fertigungsstrasse hintereinander angeordneten, aber auch beliebig im Bedarfsfall herausnehmbaren Transportwagen mit Spannvorrichtungen auszustatten, die mit möglichst geringer Raumbeanspruchung am Werkstück ansetzbar sind und die bei Nichtbedarf vôllig in bzw. unter der eigentlichen Aufstellfläche des Transportwagens zum Verschwinden gebracht werden können. Abgesehen davon ist eine solche Forderung bspw. auch für Ladeflächen von Interesse, die bspw. genormte Container aufnehmen sollen, da man bei Erfüllung dieser Forderung den betreffenden Gegenstand, von Spannvorrichtungen unbehindert, in bezug auf die Ladefläche auf-und abschieben kann.The invention relates to a support plate with a clamping device according to the preamble of the main claim. A tensioning device which has the features of the preamble of the main claim is already known from the document DD-A 135455. The further relevant prior art in this regard is represented, for example, by the following publications: DE-U 7 806 055, GB-A 778 865, US-A 3 480 271 and US-A 2 436 941. Such clamping devices are, for example, on workpiece support plates or . The like attached or put on, the clamping lever in the closed position presses the workpiece in question (for example. Body or body part) against the support plate and holds it tight. This means that the support plate around the contour of the workpiece in question is occupied with clamping devices. Modern manufacturing methods, particularly in the automotive industry, have created the requirement to equip the transport wagons arranged one behind the other in the course of a production line, but which can also be removed as required, with clamping devices which can be attached to the workpiece with as little space as possible and which are completely in or when not required. can be made to disappear under the actual footprint of the trolley. Apart from this, such a requirement is also of interest, for example, for loading areas which are to accommodate standardized containers, for example, because if this requirement is met, the object in question can be pushed up and down with respect to the loading area, unhindered by tensioning devices.

Der Erfindung liegt also die Aufgabe zugrunde, unter Voraussetzung des Vorhandenseins möglichst kleiner Durchgriffsöffnungen in der Auflagefläche eine Tragplatte mit Spannvorrichtung zu schaffen, bei der mit möglichst geringem Abstand und möglichst geringer Raumbeanspruchung der Spannhebel aus der Auflagefläche zum Auftauchen, in Spannstellung zum Werkstück geschwenkt und mit Übertotpunktverriegelung unter Spannung gebracht und umgekehrt wieder entspannt bzw. entriegelt, abgeschwenkt und versenkt werden kann.The invention is therefore based on the object, provided that the smallest possible passage openings in the support surface to create a support plate with a clamping device in which the clamping levers are swung out of the contact surface with the smallest possible distance and as little space as possible, in the clamping position to the workpiece and with The dead center lock can be energized and vice versa can be relaxed or unlocked, swiveled and lowered.

Diese Aufgabe ist durch eine Tragplatte mit Spannvorrichtung der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst. Vorteilhafte, bevorzugte und praktische Ausführungs- und Weiterbildungsformen ergeben sich nach den Unteransprüchen.This object is achieved by a support plate with a clamping device of the type mentioned according to the invention by the features stated in the characterizing part of the main claim. Advantageous, preferred and practical embodiments and further training forms result from the subclaims.

Durch die erfindungsgemässe Lösung sind die gestellten Forderungen denkbar einfach erfüllt, und es ergeben sich folgende Vorteile: Die Spannkräfte vergleichbarer «normaler» Spannvorrichtungen sind ohne weiteres erreichbar. Zum Vollzug des speziellen Bewegungsablaufes des Spannhebels ist nur ein relativ kurzer Hub von der Antriebsseite her erforderlich, was noch näher erläutert wird. Es ergibt sich eine schmale Baubreite, und die Durchgriffsöffnung an der Tragplatte für den Spannhebel braucht nur Abmessungen, die in der Breite nur geringfügig grösser sein müssen als die Dicke des Spannhebels und die in der Länge nur etwa dem Dreifachen seiner Breite zu entsprechen haben, da der Spannhebel, dessen eigentlicher Spannteil hakenartig ausgebildet ist, nur eine enge, bogenartige Bewegung ausführt. Bei Anordnung mehrerer Spannvorrichtungen an der Tragplatte können die in einer Linie nebeneinander angeordneten Spannvorrichtungen von nur einem zentralen Antriebselement aus angetrieben werden, wobei lediglich für eine entsprechende Verbindung bzw. Kopplung der Vorrichtungsteile gesorgt werden muss, in die die Antriebsbewegung einzuleiten ist. Selbstverständlich kann der Bewegungs- und Spannantrieb ausser der bevorzugten automatischen Betätigung pneumatischer oder hydraulischer Art auch von Hand erfolgen.The requirements according to the invention are met in a very simple manner by the solution according to the invention, and the following advantages result: The clamping forces of comparable “normal” clamping devices can be easily reached. To carry out the special movement sequence of the tensioning lever, only a relatively short stroke from the drive side is required, which will be explained in more detail. The result is a narrow overall width, and the passage opening on the support plate for the tensioning lever only requires dimensions that only have to be slightly larger in width than the thickness of the tensioning lever and that in length only have to be about three times its width, because the tensioning lever, the actual tensioning part of which is designed like a hook, only executes a tight, arch-like movement. If several clamping devices are arranged on the support plate, the clamping devices arranged next to one another in a line can be driven from only one central drive element, only a corresponding connection or coupling of the device parts into which the drive movement is to be initiated having to be provided. Of course, in addition to the preferred automatic actuation of pneumatic or hydraulic type, the movement and tensioning drive can also be carried out by hand.

Die erfindungsgemässe Tragplatte wird nachfolgend an Hand der zeichnerischen Darstellung eines Ausführungsbeispieles näher erläutert. Es zeigt schematisch

  • Fig.1 einen Tragplattenabschnitt mit Spannvorrichtung in versenkter Stellung;
  • Fig. 2 den Tragplattenabschnitt gemäss Fig. 1 mit Spannvorrichtung in einer Zwischenstellung beim Ausfahren;
  • Fig. den Tragplattenabschnitt mit Spannvorrichtung in Spannstellung und
  • Fig.4 eine Seitenansicht des Tragplattenabschnittes mit Spannvorrichtung.
The support plate according to the invention is explained in more detail below with the aid of the drawing of an exemplary embodiment. It shows schematically
  • 1 shows a support plate section with clamping device in the lowered position;
  • FIG. 2 shows the support plate section according to FIG. 1 with a clamping device in an intermediate position when extending;
  • Fig. The support plate section with clamping device in the clamping position and
  • 4 shows a side view of the support plate section with a clamping device.

Wie aus Fig. 1-3 erkennbar, besteht die Spannvorrichtung der Tragplatte 13 aus einem Gelenkviereck, gebildet aus den Schwingen 2, 3, dem Spannhebel 1 und aus einer festen Verbindung (Trägerplatte 13'), an der die stationären Gelenke 9, 10 der Schwingen 2, 3 angeordnet sind. Das Antriebsglied 6 ist aus einem Kniehebel 6' gebildet, dessen stationäres Gelenk 15 ebenfalls an der Trägerplatte 13' sitzt. Der Spannhebel 1 überragt mit seinem als Haken 1" ausgebildeten Spannteil 1' das Gelenk4 der Schwinge 3.As can be seen from Fig. 1-3, the clamping device of the support plate 13 consists of a four-bar linkage, formed from the wings 2, 3, the clamping lever 1 and a fixed connection (support plate 13 ') on which the stationary joints 9, 10 of the Swing 2, 3 are arranged. The drive member 6 is formed from a toggle lever 6 ', the stationary joint 15 of which is also seated on the carrier plate 13'. The tensioning lever 1 projects beyond its joint 4 of the rocker arm 3 with its tensioning part 1 ′ designed as a hook 1 ″.

Der am Gelenk 11 eingeleitete Bewegungsantrieb führt zu einer Bewegung der Teile 6', 2, 3, 1 im Sinne der eingezeichneten Pfeile, wobei bspw. die Punkte A, B des Hakens 1" die strichpunktierten, sehr schmalen Kurven durchfahren (Fig. 2). Die Stellungen gemäss Fig. 2, 3 bedürfen keiner Einzelerläuterung und dienen zur Verdeutlichung einer Zwischenstellung und der Spannstellung, bei der der Kniehebel 6' sich in etwas durchgedrückter Übertotpunktstellung befindet. Die Auftauchbewegung des als Haken 1" ausgebildeten Spannhebels 1 vollzieht sich also in einem sehr schmalen Bereich, so dass die Durchgriffsöffnung 14 in der Auflageplatte 13, unter der senkrecht die Trägerplatte 13' in geeigneter Weise befestigt ist, entsprechend klein gehalten werden kann.The movement drive introduced at the joint 11 leads to a movement of the parts 6 ' , 2, 3, 1 in the sense of the arrows shown, for example the points A, B of the hook 1 "traversing the dash-dotted, very narrow curves (FIG. 2) . the positions according to Fig. 2, 3 do not require a single illustration and serve to illustrate an intermediate position and the clamping position in which the toggle lever 6 'is in a little by holding down the over-center position. the Auftauchbewegung of the tensioning lever 1 "configured as a hook 1 thus takes place in a very narrow area, so that the passage opening 14 in the support plate 13, under which the support plate 13 'is vertically fastened in a suitable manner, can be kept correspondingly small.

Beim dargestellten Ausführungsbeispiel erfolgt der Antrieb durch einen am Gelenk 16 der Trägerplatte 13' angelenkten Pneumatikzylinder 17. Im Stellweg des Kniehebels 6' ist ein Übertotpunktanschlag 7 ebenfalls an der Trägerplatte 13' befestigt, der dafür sorgt, dass sich das Hakenende 8' bei weiterem Druck der Kolbenstange nicht wieder vom zu spannenden Gegenstand leicht abhebt und die Gelenkglieder des Kniehebels nicht nach oben durchgedrückt werden können. Die Möglichkeit der Erreichung einer Übertotpunktstellung auch bei dieser Vorrichtung ist insofern wesentlich, als die Spannstellung unabhängig vom An- oder Nichtanliegen des Druckes im Zylinder erhalten bleiben muss.In the illustrated embodiment, the drive is carried out by a on the joint 16 Carrier plate 13 'articulated pneumatic cylinder 17. In the travel of the toggle lever 6 ' , an over-dead center stop 7 is also attached to the carrier plate 13 ', which ensures that the hook end 8' does not lift off again slightly from the object to be tensioned when the piston rod is pressed further and that Joint members of the knee lever cannot be pushed upwards. The possibility of reaching an over-dead center position also with this device is essential insofar as the tensioned position must be maintained regardless of whether the pressure in the cylinder is present or not.

Wie ohne weiteres vorstellbar und wie erwähnt, kann bei Anordnung einer ganzen Reihe von Spannvorrichtungen an der Tragplatte 13, die gemäss Fig. 4 nur eine geringe Baubreite haben, senkrecht zur Darstellungsebene eine entsprechend geführte Koppelungsstange angeordnet werden, die mit einer am Ende gabelartig ausgebildeten Kolbenstange erfasstwird und wobei die Bereiche an den Gelenken 11 als Rollen ausgebildet sind, gegen die die Koppelungsstange drückt. Eine feste Verbindung der Kolbenstange mit dem Kniegelenk 11, wie dargestellt, ist nämlich - dies gilt auch für eine Einzelanordnung der Vorrichtung mit eigenem Antrieb - nicht zwingend erforderlich, da der Kniehebel 6' bei zurückgefahrener Kolbenstange des Zylinders 17 ohne weiteres mit anderen geeigneten Mitteln aus der in Fig. 3, 4 gezeigten Übertotpunktstellung herausgedrückt werden kann. Dafür könnte natürlich auch ein weiterer Stellzylinder vorgesehen werden, gekoppelt mit einem zu verstellenden Keil, der auf das Kniegelenk 11 wirkt. Derartige nur in Wirkverbindung bringbare Antriebselemente sind insbesondere für die erwähnten Transportwagen in der Autoindustrie von Interesse, da diese Wagen einzeln aus Fertigungsstrassen im Bedarfsfall und den darauf befindlichen festgespannten Werkstücken auskoppelbar sein müssen.As is easily conceivable and as mentioned, when a whole series of clamping devices are arranged on the support plate 13, which according to FIG. 4 only have a small width, a correspondingly guided coupling rod can be arranged perpendicular to the plane of the illustration, which has a piston rod which is designed like a fork at the end is detected and the areas on the joints 11 are designed as rollers against which the coupling rod presses. A firm connection of the piston rod with the knee joint 11, as shown, is namely - this also applies to a single arrangement of the device with its own drive - not absolutely necessary, since the toggle lever 6 'with the piston rod of the cylinder 17 retracted easily with other suitable means the dead center position shown in Fig. 3, 4 can be pushed out. A further actuating cylinder could of course also be provided for this purpose, coupled to a wedge to be adjusted, which acts on the knee joint 11. Such drive elements that can only be brought into operative connection are of particular interest for the transport vehicles mentioned in the automotive industry, since these vehicles must be able to be uncoupled individually from production lines if necessary and the clamped workpieces thereon.

Da die Spannvorrichtung der Tragplatte 13 äusserst kurzhubig zu bewegen ist (die Darstellungen haben den Massstab von etwa 1:1), ist es auch absolut problemlos, für einen Handantrieb zu sorgen, der bspw. mit einer geeignet bemessenen Kurve das Kniegelenk 11 nach oben drückt. Die Kurzhubigkeit der Spannvorrichtung, die dadurch auch wenig raumbeanspruchend in beengten Räumen untergebracht werden kann, kommt dadurch zustande, dass der Spannhebel 1 aus einer gewissermassen liegenden Stellung mit einer engen Bogenbewegung aufgerichtet und am Ende dieser Aufrichtbewegung wieder geringfügig nach unten gezogen und in Spannstellung gebracht wird. Der Betätigungszylinder 17 muss dabei keineswegs der Spannvorrichtung, wie dargestellt, senkrecht zugeordnet werden, sondern dieser kann unter Zwischenschaltung eines geeigneten Bewegungsumsetzers (Kurvenführungsstück od. dgl.) am Kopf der Kolbenstange auch ohne weiteres horizontal angeordnet werden.Since the tensioning device of the support plate 13 can be moved with very short strokes (the illustrations have a scale of about 1: 1), it is also absolutely unproblematic to provide for a manual drive which, for example, presses the knee joint 11 upwards with a suitably dimensioned curve . The short-stroke nature of the tensioning device, which can also be accommodated in tight spaces in a space-consuming manner, is due to the fact that the tensioning lever 1 is erected from a somewhat lying position with a narrow arc movement and, at the end of this uprighting movement, is pulled down slightly again and brought into the tensioned position . The actuating cylinder 17 does not have to be assigned vertically to the tensioning device, as shown, but this can also be arranged horizontally with the interposition of a suitable motion converter (curve guide piece or the like) on the head of the piston rod.

Die Bezeichnung «Tragplatte» ist natürlich so zu verstehen, dass es sich auch um eine Anlegeplatte handeln kann, an die der festzuspannende Gegenstand seitlich angesetzt und dann, wie beschrieben, festgespanntwird.The term "support plate" is of course to be understood in such a way that it can also be a contact plate to which the object to be clamped is attached laterally and then clamped as described.
