Description
Einrichtung an Zahnradstoßmaschinen zum Abheben des Schneidwerkzeugs von dem zu bearbeitenden Zahnrad auf dem Rückhub Bei den bish,r bekannten Zahnradstoßmaschinen wurde heim Rückhub des Schneidwerkzeugs entweder .der Aufspanntisch mit ,lern zu bearbeitenden Zahnrad gegenüber dein Werkzeug oder der Stößelträger mit Schneidrad und Stößel gegenüber "lei-n "Zahnrad verlagert. Hierbei tnußtea verhältnismäßig groß: iMassen bei jedem Hub beschleunigt und verzögert werden. Utn trotzdem die Zahnradstoßmaschine genügend starr auszubilden, mußte sie sehr kräftig geführt sein. Trotzdem mußte die Zahl der @iibe in der Zeiteinheit wegen der auftretenden großen Massenkräfte verhältnismäßig klein nein.Device on gear shaping machines for lifting the cutting tool of the gear to be machined on the return stroke In the previously known gear shaping machines The return stroke of the cutting tool either machining gear opposite your tool or the ram carrier with cutting wheel and tappet relocated to "lei-n" gear. Here tnußtea relatively large: iMass can be accelerated and decelerated with each stroke. Utn anyway To make the gear shaping machine sufficiently rigid, it had to be guided very powerfully. Nevertheless, the number of @iibe in the unit of time had to be due to the large number of occurrences Mass forces relatively small no.
Alle diese Nachteile werden bei der vorliegenden Einrichtung erfindungsgemäß dadurch vermieden, daß lediglich das Schneidwerkzeug gegenüber dem Stößel verlager: wird.All of these drawbacks are met by the present device in accordance with the present invention avoided by merely shifting the cutting tool relative to the ram: will.
Bei dieser Einrichtung kann die Arbeitsgeschwindigkeit ohne Beeinträchtigung der Arheitsgenauigkeit verdoppelt werden. Trotzdem ist der Israftbedar f kleiner.With this facility, the speed of work can be achieved without any impairment the accuracy can be doubled. Nevertheless, the israft requirement f is smaller.
Die Erfindung besteht weiterhin darin, daß die Verlagerung hydraulisch erfolgt. Die hvdrauliscbe Verlagerung hat u. a. den Vorteil; daß die Abbebung und Rückstellung des Schneidwerkzeugs am Stößel sanft erfolgt und harte Schläge vermieden werden.The invention also consists in that the displacement is hydraulic he follows. The hydraulic shift has, inter alia. the advantage; that the illustration and Resetting of the cutting tool on the ram takes place gently and hard blows are avoided will.
Erfindungsgemäß wird zur Festlegung und Zentrierung des Schneidwerkzeugs am Stößel eine radiale Stirneerzabnung verwandt.According to the invention, for fixing and centering the cutting tool a radial forehead teeth related to the ram.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt. Abb. i zeigt einen Schnitt durch Stößel und Schneidwerkzeug.An embodiment of the subject matter of the invention is shown in the drawing shown. Fig. I shows a section through the ram and cutting tool.
Abb. 2 stellt einen Schnitt nach der Linie 1-I der Abb. i dar.Fig. 2 shows a section along the line 1-I of Fig. I.
Der Stößel va, dessen Hubbewegungen auf bekannte Weise erreicht werden, hat eine Stirnverzahnung h, in welche eine Gegenverzahnung der Aufnahmescheibe c eingreift. 141,t :der Aufnahmescheibe fest verbunden ist das Schneidwerkzeug d. Die Aufnahmescheibe hat eine kugeligeAusdrehung e, gegen welche eine kugelpfa;inenart:g ausgebildete Andrehung 1i. des Zngl,o:zens i anliegt. hic Aufnahmescheibe wird durch die finit einer Kugelfläche versehene Mutter b auf dem Bolzen i gehalten.The ram above all, whose stroke movements are achieved in a known manner, has a spur toothing h, in which a counter toothing of the receiving disk c intervenes. 141, t: the cutting tool is firmly connected to the receiving disk d. The receiving disk has a spherical recess e, against which a spherical pin; inenart: g trained turning 1i. des Zngl, o: zens i is applied. hic receiving disc is through the finite spherical surface nut b is held on the bolt i.
Der zentrisch ini Stößel a geführte Zugbolzen i. hat einen Kolken h, welcher in einer Zylinderbohrung des Stößels geführt ist und als hydraulischer Kolben arbeitet. Dabei wird die Druckflüssigkeit durch die Zuführungskanäle I und in in die h::deii Zylinderräume rt und o mit dem erforderlichen Druck eingeleitet.The draw bolt i guided centrically in the ram a. has a piston h which is guided in a cylinder bore of the tappet and works as a hydraulic piston. The hydraulic fluid is fed through the supply channels I and into the h :: deii cylinder spaces rt and o with the required pressure.
Die Aufnahmescheibe c ist im Halter p schwenkbar gelagert. Zu diesem Zwecke hat.l sie eine runde Eindrehung r-. in die eine ent- j Sprechende Nase des Halters p eingreift. Der Halter p ist an einem Ring q befestigt, der um den Stötiel a. drehbar gelagert ist. Dabei wird der Rin- ,1 in.it dein Halter p durch die Stange s geführt, die am Maschinengestell befestigt ist, während der Stößel seine Abwälzdrehungen ausführt.The receiving disk c is pivotably mounted in the holder p. For this purpose it has a round recess r-. into which engages an ent j speaking nose of the holder p. The holder p is attached to a ring q, which around the stem a. is rotatably mounted. The ring, 1 in.it of the holder p is guided through the rod s, which is attached to the machine frame, while the ram makes its rolling rotations.
.Der Halter p liegt eritgegvngesetzt zu den jeweils schneidend, -n Zähnen des Schneid Werkzeugs d, utid die Lage seiner Nase bewirkt, daß beim Verschieben des Bolzens i j nach unten die Aufnahmescheibe c mit den i Schneidenden Zähnen .-les Schneidwerkzeugs d von dem Werkstück abg.:liob:i wird..The holder p is opposite to the cutting, -n Teeth of the cutting tool d, utid the location of its nose causes it to move of the bolt i j down the receiving disk c with the i cutting teeth.-les Cutting tool d is delivered from the workpiece: liob:i.
Die Einrichtung arbeitet in der Weise, daß bei Beginn de.s Arbe:--s- bzw. Schneidhubes des Stößels a nach unten der Zugbolzen i hochgezogen ist, und zwar dadurch, daß durch die Steuerung die Druckflüssigkeit in den unteren Zylinderrahm o gelangt. Damit wird die Aufnahmescheibe c in die Stirm-er zabnung b des Stößel, a. gepreßt und beide Teile somit starr miteinander verbunden. Die Stirnverzahnung legt die Aufnalitnescheibe finit dem Sclineidw#jrkzetig gegenüber dein Stößel nicht nur nach jedem Hub unverrückbar fest, sondern bringt sie auch immer in die gleiche Stellung zurück.The device works in such a way that at the beginning of the work: - s or cutting stroke of the plunger a down the pulling bolt i is pulled up, namely by the fact that the hydraulic fluid reaches the lower cylinder frame o through the control. So that the receiving disk c is in the Stirm-er zabnung b of the plunger, a. pressed and both parts are thus rigidly connected to one another. The spur toothing not only fixes the mounting disc finite to the sclineidw # jrkzetig in relation to your ram after each stroke, but also always brings it back into the same position.
Nach Beendigung des Arbeitshubes wird durch die Steuereinrichtung die Druckflüssigkeit durch den Kanal l in den oberen Zylinderraum rt geleitet und der Zugbolzen i nach unten gedrückt. Hierdurch wird die Aufnahmescheibe mit dein Schneidwerkzeug d einseitig von der Stößelspindel a abgehoben, wodurch die jeweils im Sclniitt liegenden Zähne des Schneidwerkzeugs d soweit zurückgelegt werden, daß beim Rückgang des Stö-L-els und des Schneid«-erkzetigs die Schneiden (fies Werkzeugs ohne Berührung des Werkstückes an diesem vorbeigehen.After the end of the working stroke, the hydraulic fluid is passed through the channel l into the upper cylinder space rt by the control device and the tension bolt i is pressed down. As a result, the receiving disk with your cutting tool d is lifted on one side from the ram spindle a, so that the teeth of the cutting tool d lying in the cut are moved back so far that when the hitch and the cutting force decrease, the cutting edges (nasty tool without Touching the workpiece, walk past it.
Die Schwenkung des Schneidwerkzeugs d um die Nase des Halters p braucht nur einige Millimeter betragen, um cl:e ge«-ünschteWirkung zu erzielen (die Linie -t- als Arbeitsstellung und die Linie _v als Ausschwenkstellung rletiten .die Lage des Schneidwerkzeugs an).The pivoting of the cutting tool d around the nose of the holder p takes be only a few millimeters in order to achieve the desired effect (the line -t- as a working position and the line _v as a swiveling position rletiten .the position of the cutting tool).
Die Bewegtuig des Zugbolzens kann auch mechanisch erfolgen.The tension bolt can also be moved mechanically.
