Description
Die Erfindung bezieht sich auf eine Spannvorrichtung einer Bügelsägemaschine gemäß den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a clamping device of a hacksaw according to the features specified in the preamble of claim 1.
Aus dem DE-Buch: Lich, Otto, Vorrichtungen im Maschinenbau nebst Anwendungs beispielen, Berlin, Verlag von Julius Springer, 1921, Seiten 57 bis 60, ist eine der artige Spannvorrichtung bekannt. Die vorbekannte Spannvorrichtung einer Bügelsä gemaschine enthält einen ersten Schraubstock, dessen Spannbacken eine vergleichs weise große Länge zum Festspannen eines Werkstückes aufweisen. Kurze Reststücke von Wellen, Rohren oder dergleichen können nicht ohne weiteres eingespannt und abgesägt werden. Somit konnten kurze Reststücke nicht mehr verwertet werden und kamen zum Schrott, obgleich jene oftmals aus hochwertigem Material bestehen.From the DE book: Lich, Otto, devices in mechanical engineering with application examples, Berlin, published by Julius Springer, 1921, pages 57 to 60, is one of the like tensioner known. The known clamping device of a Bügelsä machine contains a first vice, the clamping jaws of which are comparative have great length for clamping a workpiece. Short remnants of shafts, pipes or the like cannot easily be clamped and be sawed off. Thus, short remnants could no longer be used and came to the scrap, although they often consist of high-quality material.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Spannvorrichtung einer Bügelsägemaschine dahingehend weiterzubilden, daß auch kurze Reststücke funktionssicher festgespannt und weiterbearbeitet werden können. Proceeding from this, the object of the invention is the tensioning device to develop a hacksaw in such a way that even short remnants can be securely clamped and processed further.
Die Lösung dieser Aufgabe erfolgt gemäß den Merkmalen des Patentanspruchs 1.This object is achieved in accordance with the features of patent claim 1.
Die vorgeschlagene Spannvorrichtung ermöglicht bei einfacher Handhabung ein funktionsgerechtes Festspannen eines kurzen Reststückes. Aufgrund der Dreipunkt klemmung wird das zu sägende Reststück sicher und festgehalten. Wellenreststücke von 8 bis 80 mm Länge können problemlos abgesägt werden. An der Bügelsäge maschine selbst ist keine Veränderung erforderlich, und lediglich der zweite Rest stück-Schraubstock wird in den vorhandenen ersten Schraubstock der Bügelsäge maschine festgeklemmt. Der zweite Reststück-Schraubstock weist eine parallel zum Sägeblatt angeordnete Führungsplatte mit Anschlagleisten auf. Die Führungsplatte enthält einen bewegbar angeordneten Spannblock sowie Spannbacken zur Dreipunkt klemmung.The proposed clamping device enables a simple handling Functional clamping of a short remnant. Because of the three point the remaining piece to be sawn is clamped securely and securely. Shaft remnants from 8 to 80 mm in length can be sawn off without any problems. On the hacksaw machine itself, no change is required, and only the second remainder piece vice is placed in the existing first vice of the hacksaw machine clamped. The second remnant vice has one parallel to Saw blade arranged guide plate with stop bars. The guide plate contains a movably arranged clamping block as well as three-point clamping jaws clamping.
Die Erfindung wird nachfolgend an Hand der in den Fig. 1 und 2 schematisch dar gestellten Ausführungsform näher erläutert.The invention is explained below with reference to the embodiment shown schematically in FIGS. 1 and 2.
Der für das Reststück vorgesehene zweite Schraubstock wird einfach in den ersten Schraubstock der Bügelsägemaschine gestellt und festgeklemmt, wobei das Ab schnittslängenmaß vom Sägeblatt der Maschine bis zu den Anschlagleisten 7, 8 eingemessen wird. Nunmehr wird ein Spannbolzen 4 in ein entsprechendes Loch des Spannblocks 2 eingesteckt.The second vice provided for the remaining piece is simply placed in the first vice of the hacksaw and clamped, the length of section from the saw blade of the machine to the stop bars 7 , 8 being measured. Now a clamping bolt 4 is inserted into a corresponding hole in the clamping block 2 .
Anschließend wird das abzusägende Reststück an die beiden Anschlagleisten 7, 8 und die festen Spannbacken 5, 6 angelegt. Durch Betätigen einer Gewindespindel 1, wird der in eine Führungsplatte 3 geführte Spannblock 2 derart bewegt, daß das Reststück mit dem Spannbolzen 4, der im Spannblock 2 sitzt, sicher gespannt wird. Nachfolgend kann die Sägemaschine eingeschaltet und das Reststück abgesägt werden.Then the remaining piece to be sawn off is placed on the two stop bars 7 , 8 and the fixed clamping jaws 5 , 6 . By actuating a threaded spindle 1 , the clamping block 2 guided in a guide plate 3 is moved in such a way that the remaining piece is securely clamped with the clamping bolt 4 , which is seated in the clamping block 2 . The sawing machine can then be switched on and the remaining piece can be sawn off.
