Description

Vorrichtung zum Abrichten von Schleifscheiben für zahnärztliche Zwecke. Die kleinen Schleifscheiben für den Gebrauch in der Zahntechnik nützen sich ungleichmäßig ab, werden unrund und verschmieren leicht, so daß sie als unbrauchbar ausgewechselt werden müssen.Device for dressing grinding wheels for dental purposes. The small grinding wheels for use in dental technology are unevenly used from, become out of round and smear easily, so that they are replaced as unusable Need to become.

Um nun diese Schleifscheiben wieder brauchbar zu machen und gleichzeitig das häufige, lästige Auswechseln zu ersparen, dient die Vorrichtung zum Abrichten von Schleifsteinen gemäß der vorliegenden Erfindung, mit welcher der Zahnarzt während der Behandlung eines Patienten in wenigen Sekunden erstens den Stein abdrehen und schärfen, zweitens ihm eine gewünschte Form geben und drittens ihn im Falle der Verschmierung reinigen kann, ohne daß'der Stein aus dem Halter der biegsamen Welle entfernt wird. Das Abdrehen des Steines an der biegsamen Welle gewährt auch kein genaues Rundlaufen.Now to make these grinding wheels usable again and at the same time The device is used for dressing to save the frequent, annoying replacement of whetstones according to the present invention, with which the dentist during the treatment of a patient in a few seconds first twist off the stone and sharpen, secondly, give it a desired shape and thirdly, in the case of Can clean smear without the stone from the holder of the flexible shaft Will get removed. The turning of the stone on the flexible shaft also does not allow precise concentricity.

Das Werkzeug besteht aus einer Handhabe, welche das Lager für das Abrichträdchen trägt. Das Abrichträdchen selbst besteht aus mehreren nebeneinanderliegenden, runden, harten Stahlscheibchen, welche einen zickzackförmigen Umfang haben und leicht ausgewechselt werden können.The tool consists of a handle that holds the bearing for the Wears dressing wheel. The dressing wheel itself consists of several adjacent, round, hard steel washers, which have a zigzag-shaped circumference and are light can be exchanged.

Die neuartige Handhabung des Werkzeuges ist folgende: Die leicht bewegliche kleine Schleifscheibe, die durch Elektromotor oder Tretkurbelvorrichtung angetrieben wird, wird derart vor das Abrichträdchen gebracht, daß die Handhabe dem Hals der Schleifsteinwelle als Stütze dient. Durch einen kleinen Druck und eine Bewegung in Richtung der Schleifwelle erfolgt die Abdrehung der Schleifscheibe, und durch Schwenkung nach rechts und links kann jede gewünschte Form erzielt werden.The new way of handling the tool is as follows: The easily movable one small grinding wheel driven by electric motor or pedal crank device is, is brought in front of the dressing wheel that the handle is the neck of the Whetstone shaft serves as a support. With a little pressure and a movement the grinding wheel is turned in the direction of the grinding shaft, and through Pivoting to the right and left, any desired shape can be achieved.

Die Ausführungsform. kann beliebig sein; das Abrichträdchen kann links oder rechts in der Handhabe liegen, so daß beim Gebrauch die Schleifscheibe rechts oder links vom Abrichträdchen ist.The embodiment. can be anything; the dressing wheel can be left or on the right in the handle, so that the grinding wheel is on the right when in use or to the left of the dressing wheel.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung.The drawing illustrates an embodiment of the invention.

Abb. i und 2 zeigen im Grundriß das Abrichtwerkzeug für verschiedene Schleifscheibenformen.Fig. I and 2 show in plan the dressing tool for different Grinding wheel shapes.

Abb. 3 ist eine entsprechende Seitenansicht. Die Handhabe a mit anschließender Ausbauchung d trägt das Abrichträdchen b mit geeigneter Einrichtung zum Nachstellen, Feststellen und Auswechseln. Die abzurichtende Schleifscheibe c wird innerhalb der Ausbauchung d geführt.Fig. 3 is a corresponding side view. The handle a with subsequent bulge d carries the dressing wheel b with a suitable device for readjusting, locking and replacing. The grinding wheel c to be dressed is guided within the bulge d.
