Description

Vorrichtung zum Regeln des Arbeitshubes für im Kopf zahnärztlicher Winkelstücke hin und her bewegbare Werkzeughalter Die Erfindung betrifft eine Vorrichtung zum Regeln des Arbeitshubes für im Kopf zahnärztlicher Winkelstücke hin und her bewegbare Werkzeughalter.Device for regulating the working stroke for in the head dental Tool holders that can be moved back and forth The invention relates to a device to regulate the working stroke for contra-angle handpieces in the head back and forth movable tool holder.

Es ist schon eine mechanisch angetriebene Ausfeilvorrichtung für Zahnwurzelkanäle vorgeschlagen worden, bei welcher die in dem Schaft .eines Winkelstückes gelagerte Triebwelle mit der hin 'und her versch@eblichen Achse des Werkzeughalters im Querhaupt derart gekuppelt ist, daß beim Umlauf der Triebwelle die Werkzeughalterwelle sowohl um ihre Längsmittelachse hin und her gedreht als auch in Richtung dieser Achse hin und her bewegt wird.It is already a mechanically driven filing device for tooth root canals has been proposed in which the .eines elbow mounted in the shaft Drive shaft with the axis of the tool holder in the crosshead, which can be moved back and forth is coupled in such a way that when the drive shaft rotates, the tool holder shaft both rotated back and forth about its longitudinal center axis as well as in the direction of this axis and is moved here.

Es ist nun erwünscht, besonders wenn die Ausfeilvorrichtung nicht nur für die Zahnwurzelkanäle, sondern auch zum Glätten von Füllungswänden, Wurzelaußenflächen u. dgl. dienen soll, wie dies beim , Erfindungsgegenstand der Fall ist, daß der Arbeitshub des Werkzeughalters und damit des Werkzeuges verändert oder .auf eine gewisse Bewegungsgröße eingestellt werden kann.It is now desirable, especially when the filing device does not only for the tooth root canals, but also for smoothing filling walls and outer root surfaces and the like is to serve, as is the case with the subject matter of the invention that the Working stroke of the tool holder and thus of the tool changed or. To a certain amount of movement can be set.

Die Vorrichtung gemäß der Erfindung zeichnet sich durch eine im Schaft des Winkelstückes verstellbare Buchse mit kugelförmigem Drehzapfen als längs verschiebbares Lager für eine mit einem kurbielförmigen Kopf der Antriebswelle und dem Werkzeughalter gelenkig verbundene Schwinge aus. Durch Verschiebung der verstellbaren Buchse mit dem kugelförmigen Drehzapfen werden die Hebelarme der Schwinge und dadurch der Arbeitshub des Werkzeughalters verändert.The device according to the invention is characterized by one in the shaft of the angle piece adjustable socket with spherical pivot as a longitudinally displaceable Bearing for one with a crank-shaped head of the drive shaft and the tool holder articulated swing arm. By moving the adjustable socket with the spherical pivot pin becomes the lever arms of the rocker and thereby the working stroke of the tool holder changed.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise im Längsschnitt dargestellt.In the drawing is an embodiment of the subject matter of the invention for example shown in longitudinal section.

i ist das die Vorrichtung tragende Winkelstück, 2 der kurbelförmige Kopf der Antriebswelle- und iq der Kopf des Winkelstückes i, in welchem der Werkzeughalter 3' für das Werkzeug ¢a hin und her verschieblich gelagert ist. Im Schaft is des Winkelstückes i ist eine. Buchse 4 gelagert; die seine durch einen eingeschraubten Ring 5 gehaltene Gelenkkugel 6 aufnimmt. In einer Bohrung der Gelenkkugel 6 ist eine Schwinge 7 gelagert, die an beiden Enden kugelförmig ausgebildet ist und einerends in eine Aussparung 8 des einen vergrößerten Durchmesser aufweisenden Kopfes 2 der Antriebswelle und andernends in einen Querschlitz 9 des Werkzeughalters 3 eingreift. Beim Umlauf der Antriebswelle wird durch den um die Gelenkkugel 6 schwingenden Schwingbolzen 7 der Werkzeughalter 3 hin und her geschoben, wobei durch einen in der Wandung des Winkelstückkopfes 1,7 .angebrachten Längskeil io verhindert wird, daß der Werkzeughalter 3 sich drehen kann.i is the elbow bearing the device, 2 the crank-shaped one Head of the drive shaft and iq the head of the elbow i, in which the tool holder 3 'for the tool ¢ a is mounted displaceably back and forth. It's in the shaft Elbow i is a. Bushing 4 mounted; his screwed in Ring 5 held joint ball 6 receives. In a bore of the joint ball 6 is a rocker 7 is mounted, which is spherical at both ends and at one end in a recess 8 of the enlarged diameter head 2 of Drive shaft and at the other end engages in a transverse slot 9 of the tool holder 3. When the drive shaft rotates, the oscillating pin swinging around the joint ball 6 causes a 7 of the tool holder 3 pushed back and forth, whereby by a in the wall of the Elbow head 1.7. Attached longitudinal wedge io prevents the tool holder 3 can rotate.

Die Lagerbuchse q. wird durch eine durch einen in der Wandung des Schaftes is des Winkelstückes i vorgesehenen Längsschlitz i i hindurchtretende Schraube 12 in der gewünschten Stellung gehalten.The bearing bush q. is through one through one in the wall of the Shank is the angle piece i provided longitudinal slot i i screw penetrating 12 held in the desired position.

Der Schraubenkopf und der Schraubenschaft stützen sich auf eine auf dem Schaft is verschiebbar angeordnete Hülse 13 mit aufgerauhter Oberfläche ab. Nach Lösen - der Schraube 12 kann mittels der Hülse 13 die Buchse 4. mit der Gelenkkugel 6 längs verschoben werden, wodurch die Hebelarme der Schwinge 7 und dadurch der Arbeitshub des Werkzeughalters 3 und des Werkzeuges ¢a verändert werden. Hierauf wird die Halteschraube 12 wieder angezogen.The screw head and the screw shaft are supported on one the shaft is displaceably arranged sleeve 13 with a roughened surface. After loosening the screw 12, the bushing 4. with the joint ball 6 are shifted longitudinally, whereby the lever arms of the rocker 7 and thereby the Working stroke of the tool holder 3 and the tool ¢ a can be changed. On that the retaining screw 12 is tightened again.
