Description

Gegenüber den bisher bekannten umständlichen Festklemmvorrichtungen für Bohrer, die keine volle Sicherheit für festen Sitz der Bohrer bieten, wird durch den hier vorliegenden Erfindungsgegenstand ein gewerblicher und technischer Fortschritt gewährleistet. Compared to the previously known cumbersome clamping devices for drills that do not offer full security for a tight fit of the drill is through the subject of the invention presented here represents an industrial and technical advance guaranteed.

Die Klemmvorrichtung weist nach der Erfindung eine konisch gewickelte Feder mit aufgebogenem Federende zum Festhalten des eingesteckten Bohrers auf. Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. According to the invention, the clamping device has a conically wound Spring with bent spring end to hold the inserted drill. A Exemplary embodiment is shown in the drawing.

Abb. I zeigt die Abdeckklappe der Antriebswelle, Abb. 2 die Haltefeder, Abb. 3 die Antriebswelle mit Feder, Abb. 4 eine Ansicht der Kappe, Abb. 5 eine Einzelheit der Feder, Abb. 6 einen Schnitt durch die Antriebswelle. Fig. I shows the cover flap of the drive shaft, Fig. 2 the retaining spring, Fig. 3 the drive shaft with spring, Fig. 4 a view of the cap, Fig. 5 a detail the spring, Fig. 6 a section through the drive shaft.

In der Antriebswelle a steckt eine konisch gewickelte Feder e in der Ausbohrung f. Der Bohrer wird durch das in der Kappe b befindliche Loch i in die in der Antriebswelle a in der Ausbohrung f eingesteckte Feder durchgeschoben. A conically wound spring e is inserted in the drive shaft a of the bore f. The drill is inserted through the hole i in the cap b in pushed through the spring inserted in the bore f of the drive shaft a.

Es legt sich dann die in der Antriebswelle in der Ausbohrung f eingesetzte Feder e leicht um die Zylinderwand des Bohrers und hält ihn somit bei drehender Bewegung absolut sicher fest. The one inserted in the bore f of the drive shaft is then placed Spring e slightly around the cylinder wall of the drill and thus holds it in place while the Movement absolutely sure.

Eine Lockerung des Bohrers ist während der Drehung der Antriebswelle a nicht möglich, da die Feder e in ihrem konischen Teil das Bestreben hat, den Windungsdurchmesser zu verkleinern. Loosening of the drill is during rotation of the drive shaft a not possible because the conical part of the spring e tends to reduce the coil diameter to zoom out.

Im Stillstand der Antriebswelle a kann der Bohrer ohne besondere Kraftanwendung eingesteckt und herausgenommen werden. Eine Drehung der Feder e in der Ausbohrung f in der Antriebswelle a wird durch das Einrasten des Federendes el in die Auskerbung h verhindert. Die Ausnehmung g dient zur Auflage des Federendes. When the drive shaft a is at a standstill, the drill can be used without any special Force can be inserted and removed. One rotation of the spring e in the bore f in the drive shaft a is made by the locking of the spring end el prevented in the notch h. The recess g is used to support the spring end.

Die Klappe b für die Antriebswelle a ist innen plangedreht und wird, über die Antriebswelle a geschoben, durch einen Bajonettverschluß c mit an der Antriebswelle angebrachtem Stift d festgehalten, und so verhindert die Kappe b das Ausweichen der Feder e, welche mit ihrem Federende el in der Auskerbung h festrastet. The flap b for the drive shaft a is faced on the inside and is pushed over the drive shaft a, through a bayonet lock c on the drive shaft attached pin d, and so the cap b prevents the dodging the spring e, which engages with its spring end el in the notch h.
