Abstract
Description
"Schwenkbohrmaschine" "Swivel drill"
Die Erfindung betrifft eine Maschine mit der in Beton harte Körper, Stein etc. Dübellöcher oder Bohrungen für andere Verwendungen gebohrt werden können, die am Ende des Bohrloches hinterschnitten sind.The invention relates to a machine with the hard body in concrete, Stone etc. dowel holes or holes for other uses can be drilled which are undercut at the end of the borehole.
Auf der Bohr- oder Hammerbohrmaschine 1 sitzt ein Haltering 2, der über die Stangen 3 und 4 die Auflageplatte 5 hält. Die Arbeitsspindel besteht aus den Teilen 6 und 7, welche durch ein Lager 8 miteinander verbunden sind. Die Hülse 9 durch die Feder 10 gehalten, verhindert während der Herstellung des zylindrischen Teils der Bohrung ein Ausschwenken der Arbeitsspindel in ihrem Bereich 7. Der Hebel 11 greift in die Rille 12 der Hülse 9 ein. Nach Erstellung des zylindrischen Teils der Bohrung, die automatisch dann, abgeschlossen ist, wenn der Ring 5 auf der Oberfläche des zu bearbeitenden Materials aufliegt, da der Bohrer genau um das Maß, welches die Bohrtiefe ausmacht über den Ring 5 hervorsteht, wird der Hebel 11 in Richtung Auflageplatte 5 bewegt, dadurch schiebt sich die Hülse 9 ganz auf den Teil 6 der Arbeitsspindel. Die Nase 13 der Hülse 9, die sich in der Nute 14 des Teils 7 der Arbeitsspindel bewegt schwenkt den Teil 7 der Arbeitsspindel um den Drehpunkt 8 und dadurch entsteht der Hinterschnitt.On the drill or hammer drill 1 sits a retaining ring 2, the The support plate 5 holds via the rods 3 and 4. The work spindle consists of the parts 6 and 7, which are connected to one another by a bearing 8. The sleeve 9 held by the spring 10, prevented during the manufacture of the cylindrical Part of the bore swivels out the work spindle in its area 7. The lever 11 engages in the groove 12 of the sleeve 9. After creating the cylindrical part the drilling, which is automatically completed when the ring 5 is on the surface of the material to be processed, because the drill is exactly the measure that the drilling depth protrudes beyond the ring 5, the lever 11 is in the direction Support plate 5 moves, thereby pushing the sleeve 9 entirely on the part 6 of the Work spindle. The nose 13 of the sleeve 9, which is in the groove 14 of the part 7 of the Moving work spindle swivels part 7 of the work spindle around pivot point 8 and this creates the undercut.
Prinzipiell soll hier der Gedanke geschützt werden, daß eine Arbeitsspindel oder der Bohrer einer Bohr- oder Hammerbohrmaschine mit einem Gelenk versehen ist und somit geschwenkt werden kann wodurch ein Hinterschnitt im Bohrloch entsteht.In principle, the idea should be protected here that a work spindle or the drill bit of a drill or hammer drill is provided with a joint and can thus be pivoted, creating an undercut in the drill hole.
