Abstract

The clamping tool has a cantilever-end bracket end on which the movable half of the clamping mechanism with a double arm operated by a lever linkage, is adjustable by a sliding sleeve. The cantilevered part of the bracket has a blind hole in which a bolt is pivotingly fitted. The bolt is connected to a two-armed cross beam, the ends of which carry clamping jaws swivelling on axles. When the double arm is operated by the lever linkage, the cross beam, as well as the two clamping jaws adjust themselves in such a way that an optimum clamping contact is achieved on the surface of the irregular-shaped workpiece.

zur Patent- und Gebrauchsmuster-Hilfsanmeldung vom 8.7.1980 betr. Werkzeug zum Spannen bzw. Festhalten von Werkstücken.to the patent and utility model auxiliary application dated 08/07/1980 re. Tool for clamping or holding workpieces.

B e 5 c h r e i b u n g Die Erfindung bezieht sich auf ein Werkzeug zum Spannen bzw. R e p o rtio n The invention relates to a tool for clamping or

Festhalten von Werkstücken zum Zwecke des Zusammenschweißens.Holding workpieces for the purpose of welding them together.

Stand der Technik Es sind werkzeuge bekannt in Form von Schraubzwingen, die zum Festhalten von Werkstücken bestimmt sind. Auch Grippzangen sind bekannt, die durch Verschieben der Klemmbacken eine Einstellung dieser auf die verschiedenen Werkstücke ermöglichen.State of the art There are tools known in the form of screw clamps, which are intended to hold workpieces. Gripper pliers are also known by moving the jaws an adjustment of these to the different Enable workpieces.

Kritik der Technik Die Schraubzwingen und Grippzangen der bekannten Ausführung haben den Nachteil, daß sie nur eine parallele Führung haben und dadurch das Werkstück nur an einem Punkt festhalten, sodaß z. B. ein Keil mit den bisher bekannten Grippzangen nicht fest und sicher geklemmt wird, da die Klemmbacken sich dem Werkstück nicht anpassen können.Criticism of the technology The screw clamps and grip pliers of the well-known Execution have the disadvantage that they only have a parallel guide and thereby hold the workpiece only at one point, so that z. B. a wedge with the so far known grip pliers is not clamped firmly and securely because the clamping jaws are cannot adapt to the workpiece.

Aufgabe der Erfindung Der Gegenstand der Erfindung ist ein Klemmwerkzeug zum Spannen bzw. Festhalten von Werkstücken unterschiedlicher Form, bei dem sich Klemmbacken frei beweglich einem Werkstück anpassen können.Object of the invention The object of the invention is a clamping tool for clamping or holding workpieces of different shapes in which Clamping jaws can adapt freely movable to a workpiece.

Die Erfindung besteht aus einer Grippzange bekannter Konstruktion (Bild 1), die durch Federkräfte mittels eines Bügels (7) den nach oben und unten beweglichen Klemmbackenträger (6) in jeder gewünschten Lage festhält.The invention consists of gripping pliers of known construction (Fig. 1), the up and down by spring forces by means of a bracket (7) movable jaw carrier (6) holds in any desired position.

Am Klemmbackenträger (6) ist durch einen Stift (4), der in einer Hülse (5) geführt wird, ein Querbügel (3) frei beweglich gelagert. Am Querbügel (3) sind gleichfalls durch Stifte (2 und 2a) an den Enden die Klemmbacken (1 und la) frei beweglich gelagert. Zwei weitere Klemmbacken (9 und 9a) befinden sich am Zangenbügel (8).On the jaw support (6) is through a pin (4), which is in a sleeve (5) is guided, a cross bracket (3) is freely movable. Are on the cross bracket (3) also by pins (2 and 2a) at the ends of the clamping jaws (1 and la) free movably mounted. Two more clamping jaws (9 and 9a) are located on the clamp bracket (8th).

Der Vorteil der Erfindung besteht darin, daß ein zwischen den Klemmbacken (1 und la sowie 9 und 9a in Bild 2) geklemmtes Anlage (Fortsetzung der Beschreibung) zur Patent- und Gebrauchsmuster-Hilfanmeldung vom 8.7.1980 betr. Werkzeug zum Spannen bzw. Festhalten von Werkstücken.The advantage of the invention is that one between the jaws (1 and la as well as 9 and 9a in Fig. 2) clamped Annex (continued of the description) for the patent and utility model auxiliary application dated 08/07/1980 re. Tool for clamping or holding workpieces.

Werkstück beliebiger Form sicher dadurch eingeklemmt wird, daß sich der frei bewegliche Querbügel (3) mit den an den Enden frei beweglichen Klemmbacken (1 und la) dem Werkstück anpassen kann.Workpiece of any shape is safely clamped in that the freely movable transverse bracket (3) with the freely movable clamping jaws at the ends (1 and la) can adapt to the workpiece.

Die Grippzange übt durch die Federkraft auf den Zangenbügel (8) und dadurch auch auf die Klemmbacken 9 und 9a eine Kraft nach oben aus, sodaß das Werkstück durch die Klemmbacken 1 und la sowie 9 und 9a festgeklemmt wird.The gripping pliers exert the spring force on the pliers bracket (8) and this also exerts an upward force on the clamping jaws 9 and 9a, so that the workpiece is clamped by the jaws 1 and la and 9 and 9a.
