Description
Mit einen feststehenden und einen verschiebbaren Querarm aufweisenden Schraubzwingen müssen häufig Werkstücke zusammengepreßt werden, deren Begrenzuingsflächen geneigt zueinander verlaufen. L m solche Werkstücke mit geneigt zueinander verlaufenden oder gewölbten Begrenzungsflächen in einer Schraubzwinge einspannen zu können, werden Zulagen verwendet, die eine der Gestalt des Werkstückes angepaßte Form aufweisen. Es muß eine große Anzahl von Zulagen verschiedener Gestalt bereitgehalten werden, von denen die für das spez@elle Werkstück geeigneten ausgesucht und zwischen das Werkstück und die Zwinge eingelegt werden. Das Anlegen einer Schraubzivinge wird in den meisten Fällen durch zwei Personen vorgenommen, weil dieser Arbeitsgang nur mit Mühe von einer Person allein erledigt werden kann. Auch muß das Anlegen der Zwinge verhältnismäßig rasch erfolgen, damit die miteinander ztt verbindenden Holzteile, solange der Leim noch nicht erkaltet ist, in die endgültige Lage zueinander gebracht werden.With a fixed and a displaceable cross arm Clamps often have to be pressed together workpieces, their limiting surfaces run inclined to each other. L m such workpieces with inclined to one another or curved boundary surfaces to be clamped in a screw clamp Supplements used that have a shape adapted to the shape of the workpiece. A large number of allowances of various shapes must be kept ready, from which those suitable for the specific workpiece are selected and between the Workpiece and the clamp are inserted. The creation of a screw zivinge is in most cases carried out by two people, because this operation is only can be done by one person with difficulty. The creation of the Clamp done relatively quickly so that the wooden parts that are connected to each other, as long as the glue has not yet cooled down, brought into the final position in relation to one another will.
Auch bei geraden und parallel zueinander verlaufenden Preßflächen eines Werkstückes müssen häufig nachgiebige Zulagen zwischen das Werkstück und die Druckplatten eingelegt werden, wenn eine unerwünschte Verformung eines beispielsweise runden oder aus weichem Werkstoff bestehenden Werkstückes vermieden werden soll.Even with straight and parallel pressing surfaces of a workpiece often need flexible allowances between the workpiece and the Printing plates are inserted if there is an undesirable deformation of an example round or made of soft material workpiece should be avoided.
Schraubzwingen, an deren beiden Druckplatten als Drehlager ausgebildete Befestigungsvorrichtu7gen für austauschbar angeordnete, als Zulagen dienende Druckpolster vorgesehen sind, erhalten erfindungsgemäß als Drehlager Druckknopflager, wobei die Druckplatten der Zwingen als Lagerpfannen ausgebildet sind. Um eine nochvielseitigere Verwendung der Schraubzwinge zu ermöglichen, können diese Drwckknopflager auch als Kugelgelenke ausgebildet sein. Die Oberfläche der Druckpolster kann aus nachgiebigem Werkstoff bestehen, so daß weiche Hölzer ohne die Gefahr einer Beschädigung in die Schraubzwinge eingespannt werden können. Nach Wegnahme der auf die Druckplatten aufgebrachten Druckpolster kann die Schraubzivsmge in normaler Weise verwendet werden.Screw clamps, designed as pivot bearings on the two pressure plates Fastening devices for interchangeably arranged pressure cushions serving as supplements are provided, obtained according to the invention as a rotary bearing push button bearings, the Pressure plates of the clamps are designed as bearing pans. To an even more diverse one To enable use of the screw clamp, these push button bearings can also be used as a Ball joints be formed. The surface of the pressure pad can be made of flexible Material exist, so that soft woods without the risk of damage in the Screw clamp can be clamped. After removing the on the printing plates applied pressure pad, the screw can be used in the normal way.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in schematischer Weise dargestellt. Es zeigt Fig. i eine mit zusätzlichen Druckpolstern ausgerüstete Schraubzwinge, in welcher ein Werkstück mit schrägen Anpreßflächen eingespannt ist, Fig.2 einen Festarm mit einer keilförmigen, auf die Druckplatte aufgespannten Zulage, F%-.3 einen Schnitt durch den Festarm nach der Linie III-III der Fig. 2.In the drawing, an embodiment of the invention is in schematic Way presented. It shows Fig. 1 equipped with additional pressure pads Screw clamp in which a workpiece with inclined contact surfaces is clamped, 2 shows a fixed arm with a wedge-shaped extension clamped onto the pressure plate, F% -. 3 a section through the fixed arm along the line III-III of FIG.
An den Druckplatten des Festarmes i und der Schraubspindel 2 ist je ein keilförmiges Druckpolster 3 und q. angebracht, zwischen denen das Werkstück 5 eingespannt ist. Das Druckpolster ist mittels eines Druckknopfl.agers an der Druckplatte befestigt, wobei der Federring 6 in einer Aussparung der Druckplatte angeordnet ist.On the pressure plates of the fixed arm i and the screw spindle 2 is each a wedge-shaped pressure pad 3 and q. attached, between which the workpiece 5 is clamped. The pressure pad is attached to the pressure plate by means of a snap button bearing attached, the spring ring 6 arranged in a recess of the pressure plate is.
