Abstract

A clamp for a workbench has a hand lever operated clamping jaw to clamp a workpiece between the workbench and the jaw. The hand lever comprises two parallel side arms and is linked to both the jaw and to short clamping arms pivot mounted in a support block secured to the workbench. The clamping jaw has a U-shaped cross section with the middle section having a central slot and pressing onto the workpiece. The slot provides an adjustable fitting for threaded fasteners which secure the workpiece.

Die Erfindung bezieht sich auf eine Spannvorrichtung mit auf einem Lagerbock schwenkbar gelagerter, über einen Handhebel betätigter Spannbacke. Die bekannten Spannbacken bestehen aus zwei im Abstand voneinander parallel geführten Platten, zwischen denen eine Andruckspindel horizontal verschiebbar und vertikal verstellbar angeordnet ist. Die Aufgabe der vorliegenden Erfindung ist es, eine Spannvorrichtung zu schaffen, bei welcher die Spannbacke ein höheres Biegemoment aufnehmen kann und einfacher herzustellen ist. Dies wird erfindungsgemäß da-The invention relates to a clamping device with a clamping jaw that is pivotably mounted on a bearing block and operated by a hand lever. The known clamping jaws consist of two parallel plates that are spaced apart from one another, between which a pressure spindle is arranged so that it can be moved horizontally and adjusted vertically. The object of the present invention is to create a clamping device in which the clamping jaw can absorb a higher bending moment and is easier to manufacture. This is achieved according to the invention by

durch erreicht, dass die Spannbacke im Querschnitt etwa U-förmig gestaltet und in der Grundfläche ein Längsschlitz für eine in dieser längsverschieb- und feststellbare Schraube, Spindel oder dergleichen vorgesehen ist. Durch den U-förmigen Querschnitt wird ein erhöhtes Widerstandsmoment erreicht, so dass ohne Durchbiegen der Spannbacke sehr hohe Druckkräfte ausgeübt werden können. Außerdem lässt sich eine solche Spannbacke sehr einfach in einem Arbeitsgang fertigen. Vorzugsweise verlaufen die Seitenwände der Spannbacke vom Lagerbock zum freien Ende hin schräg zur Grundfläche nach unten.This is achieved by making the clamping jaw roughly U-shaped in cross-section and providing a longitudinal slot in the base for a screw, spindle or similar that can be moved lengthwise and locked in this. The U-shaped cross-section results in an increased section modulus, so that very high compressive forces can be exerted without the clamping jaw bending. In addition, such a clamping jaw can be manufactured very easily in one operation. The side walls of the clamping jaw preferably run downwards from the bearing block to the free end at an angle to the base.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Es stellen dar:The drawing shows an embodiment of the invention. It shows:

Figur 1 eine Spannvorrichtung im gespannten Zustand,Figure 1 a clamping device in the clamped state,

Figur 2 eine Draufsicht nach Fig. 1,Figure 2 is a plan view according to Fig. 1,

Figur 3 eine Vorderansicht nach Fig. 1,Figure 3 is a front view according to Fig. 1,

Figur 4 eine Darstellung nach Fig. 1 im entspannten Zustand.Figure 4 is a representation according to Fig. 1 in the relaxed state.

An den Seitenwänden 2 und 3 eines Lagerbocks 1 sind eine Spannbacke 4 und ein Zwischenhebel 5 bei 6 und 7 schwenkbar gelagert. Ein Handhebel 8 ist gelenkig mit dem Zwischenhebel 5 bei 9 und mit der Spannbacke 4 bei 10 verbunden.A clamping jaw 4 and an intermediate lever 5 are pivotally mounted at 6 and 7 on the side walls 2 and 3 of a bearing block 1. A hand lever 8 is articulatedly connected to the intermediate lever 5 at 9 and to the clamping jaw 4 at 10.

Die Spannbacke 4 ist U-förmig gestaltet, wobei die beiden Seitenwände 11 und 12 vom Lagerbock 1 zum freien Ende 13 hin schräg zur Grundfläche 14 verlaufen. Die Grundfläche 14 weist außerdem einen Längsschlitz 15 auf, in welchem in nicht dargestellter Weise eine Schraube, Spindel oder dergleichen längsverschiebbar und höhenverstellbar angeordnet ist. Durch die Gestaltung der Spannbacke 4 ergibt sich ein erhöhtes Biegemoment, so dass man größere Druckkräfte ausüben kann. Außerdem lässt sich eine solche Spannbacke 4 mit Längsschlitz 15 auf einfache Weise herstellen.The clamping jaw 4 is U-shaped, with the two side walls 11 and 12 running from the bearing block 1 to the free end 13 at an angle to the base surface 14. The base surface 14 also has a longitudinal slot 15 in which a screw, spindle or the like is arranged in a manner not shown that can be moved longitudinally and adjusted in height. The design of the clamping jaw 4 results in an increased bending moment so that greater compressive forces can be exerted. In addition, such a clamping jaw 4 with a longitudinal slot 15 can be manufactured in a simple manner.

Die Art der Verbindung zwischen dem Handhebel 8 und dem Spannbacken 4 über den Zwischenhebel 5 stellt einen Kniehebel dar. Zum Festklemmen eines Gegenstandes zwischen dem Spannbacken 4 und einer nicht dargestellten Grundfläche wird der Handhebel 8 in der Stellung nach Fig. 4 nach unten gedrückt, so dass der Zwischenhebel 5 im Uhrzeigersinn in die Stellung nach Fig. 1 schwenkt. Dabei wird die Spannbacke 4 ebenfalls entgegen dem Uhrzeigersinn mitgeschwenkt, bis die gespannte Lage nach Fig. erreicht ist. Dabei ergibt sich dann eine Totpunktstellung des Kniehebels, so dass die gespannte Lage hierdurch gesichert ist und erst durch Anheben des Hebels 8 wieder gelöst werden kann.The type of connection between the hand lever 8 and the clamping jaw 4 via the intermediate lever 5 represents a toggle lever. To clamp an object between the clamping jaw 4 and a base surface (not shown), the hand lever 8 is pressed downwards in the position shown in Fig. 4 so that the intermediate lever 5 pivots clockwise into the position shown in Fig. 1. The clamping jaw 4 is also pivoted anti-clockwise until the clamped position shown in Fig. is reached. This then results in a dead center position of the toggle lever so that the clamped position is secured and can only be released again by lifting the lever 8.
