Description
Die Erfindung betrifft eine weitere Ausbildung der Einrichtung an Zahnradstoßmaschinen zum Abheben des Schneidwerkzeugs von dem zu bearbeitenden Werkzahnrad auf dem Rückhub durch einen im Stößel verschiebbaren. mit einem Kolben versehenen Zugbolzen, der auf das rechtwinklig zur Stößelachse bewegbare Schneidwerkzeug wirkt, nach Patent 747 839.The invention relates to a further embodiment of the device Gear shaping machines for lifting the cutting tool from the work gear to be machined on the return stroke by a movable one in the ram. provided with a piston Draw bolt that acts on the cutting tool, which can be moved at right angles to the ram axis, according to patent 747 839.
Die Erfindung besteht darin, daß ein quer zur Stößelachse im Zugbolzen angeordneter, zusammen mit dem Kolben des Zugbolzens beaufschlagter Druckkolben die rechtwinklig zur Stößelachse erfolgende Bewegung bewirkt.The invention consists in that a transverse to the ram axis in the tie bolt arranged pressure piston acted upon together with the piston of the tension bolt causes the movement taking place at right angles to the ram axis.
Im übrigen bildet die Anordnung des Druckkolbens in einem im Zugbolzen durch den Hebel drehbaren Bolzen, wodurch die Richtung der rechtwinklig zur Stößelachse erfolgende Bewegung verstellbar ist, den Gegenstand der vorliegenden Erfindung.In addition, the arrangement of the pressure piston forms in a tie bolt through the lever rotatable bolt, which determines the direction of the perpendicular to the ram axis occurring movement is adjustable, the subject of the present invention.
Ein Ausführungsbeispiel des Erfindungsgegenstands ist in den Abb. i und .2 der Zeichnung dargestellt.An embodiment of the subject matter of the invention is shown in Fig. i and .2 of the drawing.
Abb. i zeigt einen Schnitt durch Stößel mit Stößelträger und Schneidrad; Abb. 2 stellt einen Schnitt nach der Linie II-II der Abb. i dar.Fig. I shows a section through the ram with the ram carrier and cutting wheel; Fig. 2 shows a section along the line II-II of Fig. I.
Die durch den Kanal 15 zugeführte Druckflüssigkeit wirkt auf den Kolben 13, der die Axialverschiebung der Hülse 12 bewirkt. An der Hülse ist das Schneidrad 20 mit geringem Spiel 54 in radialer Richtung verschieblich befestigt; sie verlagert das Schneidrad in Achsenrichtung parallel zu sich selbst.The pressure fluid supplied through the channel 15 acts on the piston 13, which causes the axial displacement of the sleeve 12. The cutting wheel 20 is fastened to the sleeve so as to be displaceable in the radial direction with little play 54; it moves the cutting wheel in the axial direction parallel to itself.
Die radiale Verlagerung des Schneidrades 20 wird durch den Kolben .I9 vorgenommen, der in der Bohrung 50 geführt ist. Der Bohrung 5o wird die Druckfliissigkeit durch den Kanal 51 zugeführt. Auch hier wieder ist der Stößel mit 4, die Aufnahmescheibe mit ig, die Stirnverzahnung zwischen Aufnahmescheibe und Stößel mit 1S und das Werkstück mit i bezeichnet.The radial displacement of the cutting wheel 20 is carried out by the piston .I9, which is guided in the bore 50. The pressure fluid is fed to the bore 5o through the channel 51. Here, too, the ram is indicated by 4, the receiving disk by ig, the spur toothing between the receiving disc and the ram by 1S and the workpiece by i.
Kanal 51, Bohrung 50 und Kolben .I9 befinden sich in dem Balzen 52, der wiederum drehbar zentrisch in der Büchse 12 gelagert ist.Channel 51, bore 50 and piston .I9 are located in the pin 52, which in turn is rotatably mounted centrally in the sleeve 12.
Die Arbeitsweise ist folgende: Die Druckflüssigkeit wird dem Zylinderraum 14 durch den Kanal i5 zugeführt. Der Kolben bewegt sich mit dem Bolzen 12 und der Aufnahme-Scheibe ig und dem Schneidrad 20 nach unten. Gleichzeitig wird- die Druckflüssigkeit durch den Kanal 51 in den Zylinderraum 5o gepreßt. Infolgedessen drückt der Kolben .I9 die aus der Verzahnung 18 herausgenommene Aufnahmescheibe mit Schneidrad in radialer Richtung fort von dem Werkstück 29. -Nunmehr bewegt sich der Stößel .I aufwärts. In der obersten Totpunktlage angekommen, wird nunmehr die Druckflüssigkeit dem Zylinderraum i; durch den Kanal 16 zugeführt. Der Kolben 13 und das Schneidrad bewegen sich in Richtung nach oben, und die Aufnahmescheibe wird in die Verzahnung iß zurückgeführt, und zwar derart, daß sie sich zwangsläufig mit der Stößelachse zentriert. Hierbei wird der Kolben 49 ebenfalls zwangsläufig in seine alte Lage zurückgeführt. Das Schneidrad ist jetzt für einen neuen Arbeitshub vorbereitet.The mode of operation is as follows: The pressure fluid is fed to the cylinder space 14 through the channel i5. The piston moves with the bolt 12 and the receiving disk ig and the cutting wheel 20 downwards. At the same time, the pressure fluid is pressed through the channel 51 into the cylinder space 5o. As a result, the piston .I9 pushes the receiving disk with the cutting wheel removed from the toothing 18 in the radial direction away from the workpiece 29. Now the ram .I moves upwards. Arrived in the top dead center position, the pressure fluid is now the cylinder space i; fed through channel 16. The piston 13 and the cutting wheel move in an upward direction, and the receiving disk is returned to the toothing in such a way that it is inevitably centered with the ram axis. Here, the piston 49 is also inevitably returned to its old position. The cutting wheel is now prepared for a new working stroke.
Am Boden 52 ist ein Hebel 53 befestigt. Dieser dient dazu, die radiale Abheberichtung zwischen Werkzeug und Werkstück festzulegen bzw. zu verändern. Diese Einrichtung hat besondere Bedeutung bei Mehrspindelmaschinen.A lever 53 is attached to the bottom 52. This serves the radial Define or change the lifting direction between tool and workpiece. These Equipment is of particular importance in multi-spindle machines.
