KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegender Bohrbügel soll Verwendung finden bei Bohrarbeiten an Eisenkonstruktiönen, im Apparate-, Schiffs- und Maschinenbau usw.The present drill yoke is to be used for drilling work on iron structures, in apparatus, ship and mechanical engineering, etc.
Bei den bereits vorhandenen ähnlichen Bohrbügeln mußte bei Vornahme rechtwinklig zueinander liegender Bohrungen (z. B. an Profileisen im Steg, Flansch oder Schenkel) die Bohrbügelstange zu der Haltevorrichtung in die jeweils erforderliche Lage geschwenkt, ausgerichtet und an derselben festgestellt werden, was zeitraubend, unbequem und lästig war.In the case of the similar drill yokes that were already in existence, you had to make them at right angles to each other horizontal bores (e.g. on profile iron in the web, flange or leg) the drilling yoke rod pivoted to the holding device in the respectively required position, aligned and to determine what was time-consuming, inconvenient and annoying.
Um diesen Übelstand zu beseitigen bzw. das Umschwenken der Bohrbügelstange überflüssig zu machen, unterscheidet sich vorliegender Bohrbügel von denen, welche bis jetzt im Gebrauch sind, dadurch, daß an dem einen Ende einer in bekannter Weise mit verschieb- und drehbar angeordnetem Widerlagerarm d versehenen Bohrbügelstange c zwei einfache U-förmige Schraubzwingen α und b befestigt sind, welche im rechten oder ungefähr im rechten Winkel zueinander liegen und mittels Druckschrauben an dem zu bohrenden Werkstück befestigt werden.In order to eliminate this inconvenience or to make swiveling the boring bar superfluous, the present boring bar differs from those which are in use up to now in that at one end a boring bar bar which is provided in a known manner with a displaceable and rotatable abutment arm d c two simple U-shaped screw clamps α and b are attached, which are at right or approximately at right angles to each other and are attached to the workpiece to be drilled by means of pressure screws.
Durch diese Anordnung der beiden Schraubzwingen an dem einen Ende der Bohrbügelstange ist es möglich, bei rechtwinklig zueinander liegenden Bohrungen den Bohrbügel direkt mittels der einen oder der anderen Schraubzwinge an der erforderlichen Stelle des Bearbeitungsgegenstandes befestigen zu können, ohne zu diesem Zwecke die Bügelstange gegen die Haltevorrichtung schwenken, ausrichten und an derselben feststellen zu müssen (Fig. 4 bis 9).This arrangement of the two screw clamps at one end of the drill yoke rod it is possible to use the drill bracket directly when the holes are at right angles to one another by means of one or the other screw clamp at the required point on the object to be processed to be able to attach without pivoting the hanger bar against the holding device for this purpose, align and to have to determine the same (Fig. 4 to 9).
