Description

Bei mit optischer Vergrößerung des Werkstückprofils oder eines Teils desselben wird auch die arbeitende Kante der Schleifscheibe von der optischen Abbildung erfaßt, damit man die Lage der -Schleifscheibe gegenüber dem Werkstück beobachten und steuern kann. Die Schleifscheibe führt beim Schleifen eine hin und her gehende Bewegung in Richtung der optischen Achse des zur vergrößerten Abbildung verwendeten, optischen System aus. Bei den bisher bekannten Profilschleifmaschinen wird die Schleifscheibenkante infolge dieser.Bewegung nur in einer bestimmten Stellung scharf abgebildet, so dä,B in der Hauptsache ein unscharfes Bild der Schleifscheibe entsteht, das nur für ganz kurze Augenblicke scharf erscheint. Dies erschwert eine einwandfreie Beobachtung und ermüdet das Auge der beobachtenden Person. Bei dem Erfindungsgegenstand sind diese Nachteile dadurch vermieden, .daß das optische System Teile besitzt, die die Bewegung der Schleifscheibe mitmachen. und einen konstanten Abstand zu derselben einhalten. Dadurch werden die Schleifscheibenkante und das Werstückprofil in jeder Stellung der Schleifscheibe scharf abgebildet. Die der Schleifscheibe am nächsten befindlichen Teile des optischen. Systems werden mit ihr bzw. dem Schleifsche.ibenträger gekuppelt, vorzugsweise so, daß man die Verbindung nach Belieben lösen. kann.For with optical enlargement of the workpiece profile or a part the working edge of the grinding wheel is also affected by the optical image recorded so that one can observe the position of the grinding wheel in relation to the workpiece and can control. The grinding wheel guides a back and forth movement during grinding Movement in the direction of the optical axis of the used for the enlarged image, optical system. In the previously known profile grinding machines, the grinding wheel edge as a result of this movement, only shown in focus in a certain position, so that B The main thing is that the image of the grinding wheel is blurred and only lasts for the whole appears sharp for a short moment. This makes perfect observation difficult and tires the eye of the observing person. In the subject matter of the invention are these disadvantages avoided. That the optical system has parts that Join the movement of the grinding wheel. and a constant distance to it retain. This will set the grinding wheel edge and the workpiece profile in each The position of the grinding wheel is shown in focus. The closest to the grinding wheel located parts of the optical. Systems are with it or the grinding wheel carrier coupled, preferably so that you can loosen the connection at will. can.

In der Abbildung ist i das Werkstück, das von der Schleifscheibe :2 bearbeitet wird. Diese ist am Schlitten 3! gelagert, der am Ständer 4 eine hin und her gehende Bewegung ausführt. Durch die Optik 5-6-7-8 wird das Werkstückprofil und die mit ihm in Berührung stehende Schleifscheibenkante auf die Fläche 9 projiziert. Der. Teil 5! der Optik, der der Schleifscheibe 2 am nächsten, steht, ist durch ein Gestänge xo mit dem Schlitten 3 und dadurch mit der Schleifscheibe 2 verbunden, so daß er die Bewegungen dieses Schlittens mitmacht und immer in konstantem Abstand zu der Schleifscheibe bleibt.In the figure, i is the workpiece that the grinding wheel: 2 is processed. This is on slide 3! stored, the back and forth on the stand 4 executes forward movement. The workpiece profile is created through the optics 5-6-7-8 and the grinding wheel edge that is in contact with it is projected onto the surface 9. Of the. Part 5! the optics, which is closest to the grinding wheel 2, is through a Linkage xo connected to the carriage 3 and thereby to the grinding wheel 2, so that he follows the movements of this sled and always at a constant distance remains to the grinding wheel.
