Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In Werkstätten und Fabriken, in welchen Metalle bearbeitet werden, sind fast immer mehrere verschiedene Bohrapparate (Bohrmaschinen , Drehbänke, Bohrknarren usf.) vorhanden, für welche Apparate in der Regel besondere Bohrsätze erforderlich sind. Die zum Aufnehmen des Bohrerhalses dienenden Löcher der Bohrspindeln sind bei den verschiedenen Apparaten meist von verschiedener Form, derart, daß die für einen Apparat passenden Bohrer für den anderen nicht passen; so z. B. sind Bohrer mit viereckigem Halse nicht für Bohrspindeln mit konischem Loch verwendbar, und umgekehrt.In workshops and factories, in which metals are processed, are almost always several different drilling devices (drills, lathes, ratchets, etc.) available, for which devices special drill kits are usually required. The ones used to hold the drill neck The holes in the drilling spindles are usually different in the various apparatuses Shape in such a way that the drills that fit one apparatus do not fit the other; so z. B. are drills with a square The jib cannot be used for drilling spindles with a conical hole, and vice versa.
Den Gegenstand vorliegender Erfindung bildet nun ein Bohrer, dessen Hals derart geformt ist, daß der Bohrer in alle üblichen Bohrapparate eingespannt werden kann. Es handelt sich dabei im wesentlichen um drei verschiedene Formen von Bohrerhälsen, die so ziemlich alle vorkommenden Fälle umfassen, nämlich die Zylinderfläche, die Kegelfläche (Morsekonus) und die vierseitige Pyramidenfiäche. The subject of the present invention now forms a drill whose neck in such a way is shaped so that the drill can be clamped in all common drilling equipment. It are essentially three different shapes of drill necks, the encompass pretty much all the cases that occur, namely the cylindrical surface, the conical surface (Morse cone) and the four-sided pyramid surface.
Damit ein ganzer Bohrersatz für die verschiedenen Bohrapparate verwendet werden kann, erhalten die Hälse der verschieden großen Bohrer den ganzen Satz hindurch teils dieselbe Dimension, d. h. dieselbe Zylinder-, Kegel- oder vierseitige Pyramidenfläche. Alle zum Festhalten des Bohrers in der Bohrspindel dienenden Flächen sind in solchem Umfange vorhanden, um beim Einspannen eine genügende Friktion gegen die entsprechenden Flächen der Bohrspindel bewirken zu können.So that a complete set of drills can be used for the various drilling attachments can, the necks of the different sized drills get partly the same dimension throughout the whole set, i. H. same cylinder, Conical or four-sided pyramid surface. All surfaces used to hold the drill in the drill spindle are in to such an extent that there is sufficient friction against the corresponding surfaces of the drilling spindle when clamping to be able to.
Der Erfmdungsgegenstand ist auf beiliegender Zeichnung dargestellt. Der Hals dieses Bohrers ist mit allen drei oben benannten Formen zum Festhalten des Bohrers in der Bohrspindel versehen. Dem Bohrer e zunächst befindet sich die Zylinderfläche a, dann die konische Fläche b, die durch eine viereckige Pyramide c teilweise abgeschnitten ist und mit einem gewöhnlichen flachen Zapfen d endet.The subject of the invention is shown in the accompanying drawing. The neck of this drill is provided with all three shapes mentioned above for holding the drill in the drill spindle. First of all, the drill e has the cylindrical surface a, then the conical surface b, which is partially cut off by a square pyramid c and ends with an ordinary flat pin d.
