Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet ein Schraubstock, bei dem das Ecken der durch ein Hebelwerk einstellbaren Backe beim Festspannen des Werkstückes mittels eines Exzenterhebels die fernere Verschiebung der Backe verhindert. Von den bekannten Schraubstöcken dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß eine mit einem Handhebel verbundene Zugstange ίο senkrecht über dem Schwerpunkt eines die bewegliche Backe tragenden Lagerarmes angreift und diesen in der Schwebe hält, so daß durch das auf der Führungssäule gelagerte Hebelwerk ein leichtes und müheloses Verstellen des Lagerarmes samt Klemmbacke in senkrechter Richtung ermöglicht wird.The subject of the invention forms a vice in which the corners of the through a lever mechanism adjustable jaw when clamping the workpiece by means of an eccentric lever prevents further displacement of the jaw. From the known vices of this type differs the subject of the invention in that a pull rod connected to a hand lever ίο engages vertically above the center of gravity of a bearing arm carrying the movable jaw and keeps it in suspension, so that it is supported by the on the guide column Lever mechanism enables easy and effortless adjustment of the bearing arm including the clamping jaw in the vertical direction.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt: The subject of the invention is shown in the drawing, namely:

Fig. ι den Schraubstock in Vorderansicht, Fig. 2 in Seitenansicht undFig. Ι the vice in front view, Fig. 2 in side view and

Fig. 3 eine Draufsicht auf Fig. 1, zum Teil im Schnitt.Fig. 3 is a plan view of Fig. 1, in part on average.

Die Säule a, die zur Führung des Lagerarmes b dient, ist an der Standplatte c durch Eingießen ο. dgl. befestigt und trägt am Kopfe ein Gabellager d zur Aufnahme des Handhebels e. Dieser dient zur senkrechten Verschiebung des Lagerarmes b und ist durch eine senkrecht über dessen Schwerpunkt angreifende Zugstange f mit ihm verbunden. Der Lagerarm b trägt verschiebbar die Klemmbacke g, die beim Einspannen des Werkstückes durch Drehen des in Lagern i, i an dem Lagerarm gelagerten Exzenterhebels k vorgeschoben wird. Um ein schnelleres Einstellen der Klemmbacke zu erreichen, ist am Lagerarm ein Führungseisen h vorgesehen. Die Klemmbacke g ist ebenso wie die feste Backe gezahnt. Die feste Backe besitzt außerdem zum Festlegen einer anderen Klemmbacke Ansätze /.The column a, which is used to guide the bearing arm b , is on the base plate c by pouring ο. Like. Attached and carries a fork bearing d for receiving the hand lever e on the head. This serves for the vertical displacement of the bearing arm b and is connected to it by a tie rod f acting vertically above its center of gravity. The bearing arm b slidably carries the clamping jaw g, which is advanced when the workpiece is clamped by turning the eccentric lever k mounted in bearings i, i on the bearing arm. In order to achieve faster adjustment of the clamping jaw, a guide iron h is provided on the bearing arm. The clamping jaw g is toothed just like the fixed jaw. The fixed jaw also has approaches / to set another clamping jaw.

Claims (1)

Patent-Anspruch:Patent claim: Schraubstock, bei dem das Ecken der durch ein Hebelwerk einstellbaren Backe beim Festspannen des Werkstückes mittels eines Exzenterhebels die fernere Verschiebung der Backe verhindert, dadurch gekennzeichnet, daß die mit dem Handhebel (e) verbundene Zugstange (f) senkrecht über dem Schwerpunkte des die bewegliche Klemmbacke (g) tragenden Lagerarmes (b) angreift und diesen in wagerechter Schwebe hält.Vice, in which the corners of the jaw, which can be adjusted by a lever mechanism, prevents further displacement of the jaw when the workpiece is clamped by means of an eccentric lever, characterized in that the pull rod (f) connected to the hand lever (e ) is perpendicular above the center of gravity of the movable clamping jaw (g) attacks the bearing arm (b) and keeps it in a horizontal position.
