Gebrauchsmusteramneldung Torrichtung zum Schleifen der Ränder von BrillengläsernUtility model registration Gate direction for grinding the edges of spectacle lenses
Vorrichtung zum Schleifen der Ränder von Brillengläsern oder ähnlichen Werkstücken, bei der die Bewegung der drehbaren Werkstückaufnahme relativ zur Schleifscheibe durch eine sich synchron mit der Werkstückaufnahme drehende Formscheibe gesteuert wird, die sich an einem Auflagestück abstützt.Device for grinding the edges of spectacle lenses or similar workpieces, in which the movement of the rotatable workpiece holder is controlled relative to the grinding wheel by a synchronously rotating form wheel with the workpiece holder, the is supported on a support piece.
Für die Randbearbeitung gibt es eine große Anzahl von Ausführungen, die sich im Prinzip immer wiederholen. Wichtig ist es heute für den Optiker und dem Weltmarkt eine Maschine anzubieten, die keine großen Wartungs- und PflegeVorschriften erfordert. Gleichfalls der Maschine und ganz besonders den Schleifscheiben eine großeThere are a large number of designs for edge processing, which in principle repeat themselves over and over again. It is important today for the optician and the world market to offer a machine that does not requires major maintenance and care regulations. same to you the machine and especially the grinding wheels
Lebensdauer zu geben, des heißt große Schleifscheibendurchmesser bei kleiner Maschinenbauweise. Die Grenzen lagen hier in der Exzenterverstellung, die naturgemäß präzise, wartungsreich nur eine kleine begrenzte Höhenverstellung zulassen.Giving service life means large grinding wheel diameters with small machine construction. The limits here lay in the eccentric adjustment, which is naturally precise and only requires a lot of maintenance allow a small limited height adjustment.
Die Erfindung sieht bei einer Vorrichtung, der eingangs genannten vor, daß die Keramikschleifscheibe 1 mittels üines Spindeltriebs 5> entsprechend ihrer Abnutzung eine Zustellung ei fährt.The invention provides for a device of the type mentioned at the beginning before that the ceramic grinding wheel 1 by means of a spindle drive 5> A delivery takes place according to its wear and tear.
Durch einen großen Hub läßt sich eine hohe Wirtschaftlichkeit erzielen.A large stroke enables a high level of economy to be achieved.
Gemäß eines weiteren Merkmales sieht die Erfindung vor, daß die Vorrichtung auf einer Grundplatte 4- das Bett 5? welches die Diamantschleifscheibe 2, die Keramikscheibe 1 und in gleicher Ebene den Antriebsmotor 6 aufnimmt.According to a further feature, the invention provides that the device on a base plate 4- the bed 5? which the Diamond grinding wheel 2, the ceramic wheel 1 and the drive motor 6 in the same plane.
In der Abb. 3 sind die Schleifscheiben ohne Berücksichtigung der Schräge gezeichnet.In Fig. 3 the grinding wheels are without taking into account the Drawn at an angle.
Auf der Grundplatte h- stützt sich das Gehäuse 7 a-b, welches einen vertikal verstellbaren Stützarm 8 trägt, an dem ein in an sich bekannter V/eise um eine horizontale Achse drehbar der Schwenkarm 9 mit der Werkstückcufnähme Io und der Formscheibe 11 gelagert ist. Die Formscheibe 11 läuft über ein Auflagestück 12 ab. Die Formscheibe 11 ruht auf einem Exzenterbolzen 1^·, mit dem das Auflagestück 12 je nach Facettentiefe eingestellt werden kann. Auf dem Auflagestück 12 ist ein Steuerelement IJ befestigt, das den Antrieb steuert. Wird das Steuerelement durch Formscheibendruck geschlossen, so findet ein Antrieb statt; hobt sich die Formscheibe 11 vom Aufla.gestück 12 ab, so wird durch Federkraft das Auflagestück 12 abgehoben, und der Antrieb steht still.The housing 7, which bears a vertically adjustable support arm 8, is supported on the base plate h , on which a pivot arm 9 with the workpiece holder Io and the shaped disk 11 is mounted so as to be rotatable about a horizontal axis in a known manner. The shaped disk 11 runs over a support piece 12. The shaped disk 11 rests on an eccentric bolt 1 ^ · with which the support piece 12 can be adjusted depending on the facet depth. A control element IJ which controls the drive is attached to the support piece 12. If the control element is closed by pressure washer, a drive takes place; If the shaped disk 11 lifts off from the Aufla.gestück 12, the support piece 12 is lifted by spring force, and the drive is at a standstill.
Vorteilig ist hierbei, gegenüber dem dauernd stetigen Antrieb, daß die Gläser nicht allzu sehr belastet werden. Gleichfalls bedarf der Arbeitsablauf einer geringeren Arbeitszeit.The advantage here is, compared to the continuously constant drive, that the glasses are not stressed too much. Likewise, the workflow requires less working hours.
Die Vorrichtung dient 'zum Kopieren der Nuten von der Leiste 18 auf die Keramikscheibe 1. Über eine Kopierleiste 18 gleitet ein Kopierbolzen 19, der der Ke re,mik scheibe 1 durch Federdruck das gleiche Profil der Kopierleiste 18 verleiht. In den bisherigen Ausführungen Abb. 8 ist jede liutanordnung zweimal in die Kopierleiste eingefräst, das erfordert hohe Präzision, Mehrarbeit und Kosten. In der Skizze Abb. 9 ist nur je eine Nut eingefräst, die der Vorrichtung eine kleine leichte Bauweise gestattet.The device is used to copy the grooves from the strip 18 on the ceramic disc 1. A copying pin 19 slides over a copier strip 18, which the Ke re, mik disc 1 by spring pressure the same profile of the copy bar 18 gives. In the previous versions Fig. 8, each line arrangement is twice in the copy bar milled, which requires high precision, extra work and costs. In the sketch Fig. 9 only one groove is milled, the allows the device to have a small, lightweight construction.
