Description

Vorrichtung zum Abrichten von Gewindeschleifscheiben Es ist bei Vorrichtungen zum Abrichten von Gewindesch1eifscheiben bekannt, den Diamantträger um das Abrundungszentrum der Schleifscheibe schwingbar und in Flankenrichtung verschiebbar anzuordnen.Device for dressing thread grinding wheels It is with devices known for dressing thread grinding disks, the diamond carrier around the rounding center to arrange the grinding wheel so that it can swing and move in the direction of the flank.

Diese Abziehvorrichtungen genügen jedoch nicht den Anforderungen der Praxis, da sie nur konvexe Abrundungen erzielen können.However, these pullers do not meet the requirements of Practice as they can only achieve convex fillets.

Dieser Nachteil wird.durch die Erfindung [dadurch beseitigt, daß radial zur Schwingachse und in radialer Richtung einstellbar ,ein zweiter Diamantträger vorgesehen ist, wodurch sowohl ein. konkaves wie auch konvexes Abrunden der Fläche zwischen zwei Flanken einer Gewindeschleifscheibe möglich wird.This disadvantage is.by the invention [in that radial adjustable in relation to the swing axis and in the radial direction, a second diamond carrier is provided, whereby both a. concave as well as convex rounding of the surface is possible between two flanks of a thread grinding wheel.

In der Zeichnung ist der Gegenstand der Erfindung dargestellt, und zwar zeigt Abb. i eine Vorderansicht, Abb. 2 verschiedene Stellungen der AbziehvorrIchtung.In the drawing, the object of the invention is shown, and although Fig. 1 shows a front view, Fig. 2 shows different positions of the puller.

Im wesentlichen besteht die Abziehvorrichtung aus einem einstellbaren Lagerblock 17, in dem die Schwenkachse 18 der Abziehvorrichtung in geeigneter Weise gelagert ist. Die Mittelachse dieser Schwenkachse 18 ist so zur Schleifscheibe einstellbar, daß sie durch den Mittelpunkt der Spitzenabrundung hindurchgeht. An dieser Schwenkachse ist die eigentliche Abziehvorrichtung i9 befestigt, deren einer Abziehdiamant 28 von einer Zahnstange 3o getragen wird, die mit einem Zahntrieb 3 i in Eingriff steht, der durch den Hebel 29 in dem einen oder anderen Sinne verdreht werden kann, wodurch die Zahnstange 30 zwei. verschiedene Bewegungen ausführt, die notwendig sind, um beide Flanken der Schleifscheibe bearbeiten zu können..The puller essentially consists of an adjustable bearing block 17 in which the pivot axis 18 of the puller is mounted in a suitable manner. The central axis of this pivot axis 18 can be adjusted relative to the grinding wheel in such a way that it passes through the center point of the rounded tip. The actual extractor i9 is attached to this pivot axis, one of which is carried by a rack 3o, which is in engagement with a rack 3i, which can be rotated in one sense or the other by the lever 29, whereby the rack 30 two. performs various movements that are necessary in order to be able to machine both flanks of the grinding wheel.

Neben -dem Abziehdiamanten 28 ist aber noch ein zweiter Abziehdiamant 26 vorgesehen, der beim Schwenken. der Abziehvorrichtung einen Radius beschreibt, und zwar wird diese Abrundung je nach der Stellung ;des Abziehdiamanten 26, der durch eine Stellvorrichtung 27 axial verschoben werden kann, entweder eine konvexe oder konkave Abrundung erzeugen, j e nachdem ob der Diamant oberhalb der Mittelachse der Welle 18 liegt oder unterhalb derselben.In addition to diamond 28, there is a second diamond 26 provided that when pivoting. the puller describes a radius, and this rounding is depending on the position; of the diamond 26, the can be moved axially by an adjusting device 27, either a convex one or create a concave rounding, depending on whether the diamond is above the central axis the shaft 18 is or below the same.

Selbstverständlich wird man die Bewegung der Abziehvorrichtung' mit Rücksicht auf den zu erzeugenden Flankenwinkel durch besondere einstellbare Anschläge begrenzen, die jedoch in der Zeichnung nicht dargestellt sind.Of course, you will see the movement of the puller Consideration of the flank angle to be generated through special adjustable stops limit, which are not shown in the drawing.
