Elektrisch betriebene Handbohrmaschinen finden in den verschiedensten Betrieben Anwendung, eignen sich jedoch naturgemä'fs weniger für Ausführung von Bohrarbeiten, die absolute Genauigkeit erfordern, da die Führung der Maschinen von Hand aus bewerkstelligt wird.Electrically operated hand drills are used in a wide variety of companies, However, they are naturally less suitable for carrying out drilling work that is absolute Require accuracy as the machines are managed by hand.
Vorliegende Erfindung bezweckt, elektrisch betriebene Handbohrmaschinen in einfachster Weise auch für genauere und Präcisionsarbeiten in Werkstatt und auf Montage brauchbar zu machen.The present invention aims to provide electrically operated hand drills in the simplest possible way Also useful for more precise and precision work in the workshop and on assembly do.
Zu dem Zweck ist, wie in beiliegender Zeichnurig Fig. i, 2, 3 und 4 dargestellt, die Handbohrmaschine α mit dem Fufs b in einen Schlitten c eingesetzt und wird in diesem durch die Schrauben d festgehalten. Der Schlitten c bewegt sich in verticaler Richtung in der Geradführung e des Ständers f. Der Ständer ist mit den Füfsen g versehen und nimmt in der hohlen Aussparung· h das Gegengewicht i auf, welches durch die über das Rad k laufende Kette/ mit dem Schlitten c verbunden ist. Durch das Gegengewicht i findet ein Ausbalanciren der Bohrmaschine α statt und können auf diese Weise, da die Maschine durch den Schlitten c genau geführt wird, Bohrarbeiten mit gröfster Genauigkeit und Präcision ausgeführt werden. Andererseits ist es möglich, nach Lösen der Schrauben d die Bohrmaschine a jederzeit als transportable Handbohrmaschine zu benutzen.. An Stelle des Gegengewichtes i kann natürlich auch, wie in Fig. 5 dargestellt, eine Spindel m mit Handrad η angewendet werden, um das Auf- und Abbewegen des Bohrapparates zu bewirken. Auch kann, wie in Fig. 6 dargestellt, der Schlitten c in der Weise ausgebildet werden, dafs die Bohrmaschine von demselben vollständig umschlossen wird.For this purpose, as shown in the accompanying drawing Figs. I, 2, 3 and 4, the hand drill α is inserted with the foot b in a carriage c and is held in this by the screws d . The slide c moves in the vertical direction in the straight guide e of the stand f. The stand is provided with the feet g and in the hollow recess h receives the counterweight i , which is carried by the chain / with the slide running over the wheel k c is connected. The counterweight i balances the drilling machine α and in this way, since the machine is guided precisely by the slide c , drilling work can be carried out with the greatest possible accuracy and precision. On the other hand, it is possible after releasing the screws, the drill d a anytime as a portable hand drill to use .. In place of the counterweight i can of course, as shown in FIG. 5, a spindle m are applied η with handwheel to the ascent and to cause the drilling apparatus to move away. Also, as shown in FIG. 6, the slide c can be designed in such a way that the drilling machine is completely enclosed by the same.
