Description
Vorrichtung zum Abrichten profilierter Schleifscheiben mittels umlaufender profilierter Abrichtwerkzeuge. Man kennt bereits Vorrichtungen zum Abrichten profilierter Schleifscheiben mittels umlaufender profilierter Abrichtwerkzeuge.Device for dressing profiled grinding wheels using rotating profiled dressing tools. Devices for dressing more profiled are already known Grinding wheels using circumferential profiled dressing tools.
Die neue Vorrichtung ist dadurch gekennzeichnet, daß zur Erhöhung der Angriffswirkung das Abrichtwerkzeug aus einzelnen radial angeordneten Lamellen besteht, in denen das Profil ausgespart ist.The new device is characterized in that to increase the attack effect the dressing tool from individual radially arranged lamellae consists in which the profile is recessed.
Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführungsform dargestellt. Die Maschine besitzt ein Bett j, welches die durch .einen Riemen l angetriebene Schleif -scbeibe k trägt. in ist ein Schlitten, der- durch ein Handrad auf das Schleifrad zu bewegt oder von diesem fortbewegt werden kann, und o ist ein Querschieber auf dem Schlitten, der das Abrichtwerkzeug nach der Erfindung trägt.The subject of the invention is shown in the drawing in one embodiment. The machine has a bed j which carries the grinding disc k driven by a belt l. in is a carriage which can be moved towards or away from the grinding wheel by a handwheel, and o is a cross slide on the carriage which carries the dressing tool according to the invention.
Das Werkzeug hat, wie die Zeichnung zeigt, die Form einer in der Längsrichtung (bei; 65) genuteten Walze 64 und weist mehrere Ringnuten 66 auf, deren Querschnitt genau der herzustellenden Form des. Werkstückes entspricht.As the drawing shows, the tool has the shape of a roll 64 grooved in the longitudinal direction (at; 65) and has several annular grooves 66, the cross-section of which corresponds exactly to the shape of the workpiece to be produced.
In Wirklichkeit ist die Walze mit ebner verhältnismäßig großen Anzahl von Längsnuten 65 und Radiallamellen versehen, so daß also in jeder Ringnut 66 ebenso zahlreiche Kanten 67 zur Wirkung kommen können. In der Ab= bildung .ist die Walze nur mit wenigen Längsnuten versehen dargestellt, um die Zeichnung nicht unklar zu machen. Die Anzahl der Quernuten 66 kann verschieden sein. Um die richtige Stellung des: Schleifrades und der Abrichtwalze in bezug aufeinander während der Arbeit zu sichern, ist die Walzei in der Achsrichtung frei beweglich. Sie kann z. B. auf einer Spindel 68, .auf welcher sie drehbar ist, in der Längsrichtung verschiebbar angeordnet sein.In reality, the roller is relatively large in number provided by longitudinal grooves 65 and radial lamellas, so that in each annular groove 66 as well numerous edges 67 can come into effect. In the picture. Is the roller shown provided only with a few longitudinal grooves in order not to obscure the drawing do. The number of transverse grooves 66 can be different. About the right position of the: grinding wheel and the dressing roller in relation to each other during work secure, the roller is freely movable in the axial direction. You can z. B. on one Spindle 68, on which it is rotatable, is arranged displaceably in the longitudinal direction be.
Während die Walze gegen das Schleifrad bewegt wird, dreht man dieses langsam durch Handzug an den Riemen I, wodurch natürlich die Walze in der umgekehrten Richtung, aber im wesentlichen mit der gleichen Umfangsgeschwindigkeit gedreht wird wie, das Schleäfrad. Die Lamellenkanten 67 üben auf das Schleifrad eine mahlende oder schlagende Wirkung aus, infolge deren sehr kleine Teilchen von dem Rade abgebrochen werden, wodurch das Profil schnell und genau auf die Form der Quernut in der Walze gebracht wird; z. B. des .einzuschleifenden Whiteworth-Gewindes.While the roller is being moved against the grinding wheel, it is turned slowly by hand pulling on the belt I, which of course causes the roller in the reverse Direction, but is rotated essentially at the same peripheral speed like, the grinding wheel. The flap edges 67 exert a grinding effect on the grinding wheel or beating effect, as a result of which very small particles broke off the wheel so that the profile quickly and precisely matches the shape of the transverse groove in the roller is brought; z. B. the whiteworth thread to be looped in.
Obgleich die Wirkung einer jeden Kante auf das Rad ,an und für sich ,äußerst gering ist, so wird sich doch die Gesamtwirkung dieser schnell hintereinander auf das Rad wirkenden Kanten sehr schnell. bemerkbar m a chen.Although the effect of each edge on the wheel, in and of itself , is extremely small, the overall effect of these will change quickly one after the other edges acting on the wheel very quickly. to make noticable.
Wenn eine: der Nuten der Walzen- durch Gebrauch ,abgenutzt ist, kann der Querschieber o so verschöben werden, daß .eine andere: Nut 66 in die Abrichtstellung gebracht wird; äst das Schleifrad durch die zweite Nut abgerichtet, kann es dazu dienen, die abgenutzte Nut auf die; richtige Form zu schleifen. Dazu wird das Schleifrad schnell gedreht, während die Walze langsam in der gleichen Richtung gedreht wird, so daß die Walze und das, Rad sich an ihren Berührungspunkten mit ungleichen Geschwindigkeiten in die umgekehrten Richtungen drehen.If one of the grooves of the rollers is worn out through use, it may the cross slide o are shifted so that. Another: groove 66 in the dressing position is brought; If the grinding wheel is dressed through the second groove, it can do so serve the worn groove on the; grind correct shape. This is done using the grinding wheel rotated quickly while the platen is rotated slowly in the same direction, so that the roller and the wheel move at their points of contact with unequal speeds rotate in the opposite directions.
