Description

Bei Werkzeugmaschinen mit hin und her gehendem Tisch, insbesondere Hobelmaschinen, wird der Vorschub für die Werkzeuge von einer senkrecht stehenden Welle abgeleitet, der man eine Schwenkbewegung erteilt, die von dem hin und her gehenden Tisch gesteuert wird. Die bisher bekannten mechanischen und elektrischen Antriebsmittel für die senkrechte Welle, nachstehend kurz als Schaltwelle bezeichnet, haben den Nachteil, daß sie dauernd durchlaufen, während die Schaltwelle immer nur jeweils im Augenblick der Tischumsteuerung ihre Schwenkbewegung ausführen darf. Dies kann dann immer, nur mit erheblichen Stößen erfolgen, die durch die notwendigen und nicht zu umgehenden Beschleunigungen 'hervorgerufen werden.In machine tools with a reciprocating table, in particular Planers, the feed for the tools is from a vertical one Derived wave, which is given a pivoting movement, which is back and forth from the walking table is controlled. The previously known mechanical and electrical Drive means for the vertical shaft, hereinafter referred to as switching shaft for short, have the disadvantage that they go through continuously while the switching shaft only ever may execute their swivel movement at the moment the table is reversed. This can always be done only with considerable impacts caused by the necessary and not too immediate accelerations'.

Die vorliegende Erfindung vermeidet diesen Nachteil durch Zwischenschaltung eines Dämpfungsmittels und vereinfacht gleichzeitig den sonst notwendigen, nicht ganz einfachen Aufbau mechanischer Antriebsarten für die Schaltwelle in der bisher üblichen Weise.The present invention avoids this disadvantage by interposing it a damping means and at the same time does not simplify the otherwise necessary very simple structure of mechanical drive types for the selector shaft in the previous one usual way.

Die an dem hin und her gehenden Tisch befestigten Steuerknaggen 2 und 3 betätigen durch Umlegen des Hebels q über die Kolbenstange 5 den Kolben 6 im Zylinder 7. Je nach Bewegungsrichtung des Kolbens wird dabei Zylinderraum 8 oder 9 unter Druck gesetzt. Dieser Öldruck wird dazu benutzt, um, jeweils über die Leitungen 1o, 11, die Zylinderräume 12 oder 13 die Kolben 16 oder 18 zu beaufschlagen. Diese beiden Kolben sind durch eine verzahnte Stange 17 so miteinander verbunden, daß bei der durch die Kolbenbeaufschlagung verursachten Bewegung ein Ritzel 19 betätigt wird, das seine Sc'hwerilebe\aegung unmittelbar auf die Schaltwelle 20 überträgt. Werkstattgemäß wird der Schaltwellenantrieb in einem Gehäuse 2. untergebracht. Um die Räume 8 und 9 bei der Kolbenbewegung stets mit 01 gefüllt zu halten, ist über Zylinder 7 ein Behälter 23 angeordnet, aus dem über die durch Kugeln 21 bei auftretendem Druck verschlossenen Leitungen 22 die erforderlichen Ölmengen nachfließen können.The control lugs 2 and 3 attached to the moving table actuate the piston 6 in the cylinder 7 by moving the lever q over the piston rod 5. Depending on the direction of movement of the piston, cylinder space 8 or 9 is pressurized. This oil pressure is used to act on the pistons 16 or 18 via the lines 1o, 11, the cylinder spaces 12 or 13, respectively. These two pistons are connected to one another by a toothed rod 17 in such a way that a pinion 19 is actuated during the movement caused by the action of the piston, which pinion transmits its shifting movement directly to the shift shaft 20. According to the workshop, the selector shaft drive is housed in a housing 2. In order to keep the spaces 8 and 9 always filled with 01 during the piston movement, a container 23 is arranged above the cylinder 7, from which the required quantities of oil can flow through the lines 22 closed by balls 21 when pressure occurs.
