Description

Pateντ-Anspruch:Pateντ claim:

Drehbank- und Bohrfutter mit durch eine konische Ueberschiebehülse radial verstellbaren Klemmbacken, dadurch gekennzeichnet, dafs die mit ihrem äufseren Gewinde im Gewindetheil (b) des Futterkörpers (a) verstellbare Ueberschiebehülse (d) noch durch einen auf einem Konus des Futterkörpers aufgepafsten Cylinder centrisch geführt wird.Lathe and drill chucks with clamping jaws radially adjustable by means of a conical sliding sleeve, characterized in that the sliding sleeve (d) which can be adjusted with its outer thread in the threaded part (b) of the chuck body (a) is still guided centrically by a cylinder fitted onto a cone of the chuck body .

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Das Drehbank- und Bohrfutter besteht aus dem eigentlichen Futterkörper oder Schaft a mit einem hülsenförmigen Ansatz b mit Innengewinde. Der Schaft α läuft vorn in einen Kegel aus, über den ein Cylinder c geschoben ist. Die Ueberschiebehülse d greift mit ihrem äufseren Gewinde in das Innengewinde von b und wird nicht allein durch dieses, sondern auch noch durch den Cylinder c centrisch geführt. The lathe and drill chuck consists of the actual chuck body or shank a with a sleeve-shaped extension b with an internal thread. The shaft α ends at the front in a cone over which a cylinder c is pushed. The sliding sleeve d engages with its external thread in the internal thread of b and is guided centrically not only through this but also through the cylinder c . Die Gewinde von b und d werden gleichmäfsig beansprucht und abgenutzt, verlieren daher nicht an Genauigkeit. Zwischen Cylinder c und Hülse d ist die Reibung sehr klein, andererseits bietet Hülse b dadurch, dafs dieselbe unmittelbar mit der Spindel verbunden ist, dem Futter den gröfsten Widerstand gegen seitlichen Druck oder Schlag. Durch das Zusammenwirken dieser Umstände wird eine ebenso grofse wie dauernde Genauigkeit und Stabilität erreicht.The threads of b and d are stressed and worn evenly and therefore do not lose their accuracy. The friction between cylinder c and sleeve d is very small; on the other hand, sleeve b , because it is directly connected to the spindle, offers the chuck the greatest resistance to lateral pressure or impact. Through the interaction of these circumstances an accuracy and stability which is as great as it is lasting is achieved. Durch die Ueberschiebehülse d werden die Backen e (wie bekannt) radial verstellt und erhalten, um möglichst verschieden starke Bohrer einspannen oder verschieden dicke Werkstücke bearbeiten zu können, schlittenförmige Klemmstücke h, die durch andere Klemmstücke ersetzt werden können.The jaws e are Through the sliding sleeve d (as is known) adjusted radially and maintained clamped to different possible strong drill or edit various thickness workpieces, h sled-shaped clamping pieces which can be replaced by other clamping pieces. Die Backen haben ihr Widerlager in einem beweglichen Ringe g am Cylinder c und werden auch durch diesen zurückgehalten; Cylinder c wird weiter zurückgehalten durch die beiden Ansätze f und einen oder zwei Bolzen (mit Gewinde oder Feder).The jaws have their abutment in a movable ring g on the cylinder c and are also held back by this; Cylinder c is further held back by the two lugs f and one or two bolts (with thread or spring). Bei dem Zusammensetzen werden die Backen e in die Nuthen der Hülse d und gleichzeitig des Ringes g geschoben und darauf der Ring g mit dem Cylinder c verschraubt.During assembly, the jaws e are pushed into the grooves of the sleeve d and, at the same time, of the ring g, and then the ring g is screwed to the cylinder c. Das Ganze wird auf den Konus des Futterkörpers gesteckt und bei den Ansätzen f verbolzt. The whole thing is put on the cone of the chuck body and bolted at the approaches f.
