Description
Es ist gelegentlich notwendig, den Corneateil von Haftgläsern nachzubearbeiten. Bestehen diese Haftgläser aus transparenten Kunststoffen, z. B. aus Polyakrylsäureester, so kanh man den Drehstahl dazu zu Hilfe nehmen, denn es ist bekannt, daß die in der Augenglasbearbeitung verwendeten organischen Kunststoffe spanabhebend bearbeitbar sind. It is occasionally necessary to rework the corneal part of adhesive glasses. Are these adhesive glasses made of transparent plastics, e.g. B. from polyacrylic acid ester, so you can use the turning tool for this, because it is known that the in Organic plastics used in eyeglass machining can be machined are.
Mit dem Erfindungsgegenstand ist es möglich, diese spanabhebende Bearbeitung rationell durchzuführen. Erfindungsgemäß ist vorgesehen, die Haftgläser in einen U-förmigen Bügel einzuspannen, der das Widerlager für das von einem Stempel belastete Haftglas bildet. Dieser Bügel ist ein Teil einer Drehspindel. Als Support dient ein Schlitten, der einen zweiten Support für das Bearbeitungswerkzeug trägt und der exzenter- bzw. kurbelgesteuert ist. Diese Art -der Steuerung hat gegenüber anderen Möglichkeiten den Vorzug, daß der Schlitten verstellbar ist, daß ihm ein großer Verstellhub gegeben werden kann und daß mit ihm in der Nähe der Totpunktstellung des Exzenters eine große Kraft in Richtung des Werkstückes ausübbar ist. With the subject matter of the invention, it is possible to cut this Processing to be carried out efficiently. According to the invention it is provided that the adhesive glasses to clamp in a U-shaped bracket, which is the abutment for a stamp loaded adhesive glass forms. This bracket is part of a turning spindle. As support a slide is used that carries a second support for the machining tool and which is eccentric or crank controlled. This type of control has opposite other possibilities have the advantage that the slide is adjustable that him a large adjustment stroke can be given and that with it in the vicinity of the dead center position of the eccentric a large force can be exerted in the direction of the workpiece.
SchlieBlich ist bei der erfindungsgemäßen Vorrichtung der Träger um einen quer durch die Achse des Stempels gehenden Bolzen schwenkbar gelagert. Finally, in the device according to the invention, the carrier is mounted pivotably about a bolt going transversely through the axis of the punch.
In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt, und zwar zeigt Abb. 1 eine Draufsicht auf die Vorrichtung, Abb. 2 eine schaubildliche Ansicht der Spannvorrichtung. In the drawing, an embodiment is shown schematically, namely, Fig. 1 shows a plan view of the device, Fig. 2 is a perspective view View of the clamping device.
Der Bügel I ist Teil einer Drehspindel. In ihm ist der Stempel 2 axial verschiebbar gelagert und beispielsweise federbelastet. Weiche Beilagen 3 verhindern eine Beschädigung des eingespannten I-Iaftglases 4. The bracket I is part of a rotating spindle. In it is the stamp 2 axially displaceable and, for example, spring-loaded. Soft side dishes 3 prevent damage to the clamped I-Iaftglass 4.
Zur Vorrichtung gehört ferner der in an sich bekannter Weise in Längsrichtung geführte Schlitten 5, der mit Hilfe der um den Zapfen 6 schwenkbaren Exzenterscheibe 7 und der Kurbelstange 8 verstellbar ist. L)ie Verstellung erfolgt durch Verschwenken des Handgriffes 7a Auf dem Schlitten 5 ist der Träger g des Drebstahles IO um den Bolzen 1 1 schwenkbar gelagert. Der Drehstahl IO ist in Längsrichtung mit Hilfe der Schraube I2 verschiebbar. Die Pfeile deuten die Richtungen an, in denen die Hauptteile der Vorrichtung verstellbar sind. The device also includes the in a known manner in the longitudinal direction guided carriage 5, with the help of the pivotable about the pin 6 eccentric 7 and the connecting rod 8 is adjustable. L) he adjustment takes place by pivoting of the handle 7a On the carriage 5, the carrier g of the rotary pick IO is around the Bolt 1 1 pivoted. The turning tool IO is longitudinally using the screw I2 can be moved. The arrows indicate the directions in which the Main parts of the device are adjustable.
PATENTANSPRUCME: I. Vorrichtung zum Abdrehen und Festspannen von Haftgläsern aus thermoplastischen Kunststoffen, gekennzeichnet durch einen auf einem kurbelgesteuerten Schlitten (5) schwenkbar gelagerten Werkzeugträger (9, IO) sowie durch einen U-förmigen Bügel (1) zum Festspannen des Haftglases, der in seiner Brücke eine Durchtrittsöffnung aufweist, deren Durchmesser größer ist als der Maximaldurchmesser des Corneateiles des I laftglases, und mit dem an seiner Stirnfläche entsprechend der Innenfläche des Corneateiles gewölbtem Zentrierstempel (2) axial verschiebbar und gegebenenfalls gleichachsig drehbar ist. PATENT CLAIMS: I. Device for turning and tightening Adhesive glasses made of thermoplastics, characterized by one on one crank-controlled slide (5) pivotably mounted tool carriers (9, IO) and by a U-shaped bracket (1) for clamping the adhesive glass in its bridge has a passage opening whose diameter is larger than the maximum diameter of the corneal part of the laft glass, and with that on its end face accordingly the inner surface of the corneal part arched centering punch (2) axially displaceable and can optionally be rotated coaxially.
