Description

Rundschalttisch Nach Erreichen dieser in Fig. 1 rechte Hälfte dargestellten Stellung "Entriegelt" wird über den Kanal 25 (Fig. 2) der durch die Lippendichtung 26 abgedichtete Kolben 27 mit Druckluft beaufschlagt. Die Druckluft schiebt den an einer Seite als Zahnstange 28 ausgebildeten Kolben 27 nach links.Rotary indexing table After reaching this "unlocked" position shown in the right half of FIG. 1, the piston 27 sealed by the lip seal 26 is acted upon by compressed air via the channel 25 (FIG. 2). The compressed air pushes the piston 27, which is designed as a toothed rack 28 on one side, to the left.

Das mit der Zahnstange 28 kämmende Zahnrad 22 bewegt sich und mit ihm die Welle 14 und die Tischplatte 15 (Fig. 1) entgegen dem Uhrzeigersinn. Diese Drehbewegung erfolgt solange, bis die in einer Bohrung im Kolben 27 (Fig. 2) befindliche, durch den Stift 29 mit dem Kolben 27 verbundene Buchse 30 gegen den Anschlagbolzen 31. anstößt. Die Buchse 30 ist mit den Schlitzen 32, 33 und 34 versehen.The gear 22 meshing with the rack 28 moves, and with it the shaft 14 and the table top 15 (FIG. 1), counterclockwise. This rotary movement continues until the bushing 30 , which is located in a bore in the piston 27 (FIG. 2) and connected to the piston 27 by the pin 29, strikes the stop pin 31. The socket 30 is provided with the slots 32, 33 and 34.

Die Begrenzung erfolgt durch Ansdhlag der Fläche 35 der sich mit dem Kolben 27 bewegenden Schlitzbuchse 30 gegen die Fläche 36 der paßfederähnlichen Erhöhung 37 am Anschlagbolzen 31. Die Länge der in der Anzahl, beliebigen Nuten 32, 33 und 34 bestimmen somit den Weg des Kolbens 27 und dadurch den Drehwinkel des Zahnrades 22 und der Tischplatte 15 (Fig. 1).The limitation is made by abutment of the surface 35 of the slotted bushing 30 moving with the piston 27 against the surface 36 of the feather key-like elevation 37 on the stop pin 31 and thereby the angle of rotation of the gear 22 and the table top 15 (Fig. 1).

Wird der Anschlagbolzen 31 (Fig.2) an dem durch den Stift 38 mit ihm verbundenen Verstellknopf 39 aus der gezdichneten, der Nute 32 entsprechenden Stellung in eine Stellung gedreht, die der Nute 33 oder der Nute 34 entspricht, so wird der Weg des Kolbens 27 und damit der Drehwinkel der Tischplatte 15(Fig.l). vergrößert. Die Wahl des Drehwinkels und damit des Teilschrittes der Tischplatte erfolgt also erfindungsgemäß durch Zuordnen der Erhöhung 37 (Fig.2) des Bolzens 31 zu einer entsprechend langen Nute 32 oder 33 oder 34 der Schlitzbuchse 30. Außerdem werden die mit einem Gewinde versehenen Lager-Buchsen 47 und 48 gleichzeitig zum Einspannen der Membranen 12 bzw. 49 an deren Bohrungsdurchmesser verwendet.If the stop bolt 31 (FIG. 2) is rotated on the adjusting knob 39 connected to it by the pin 38 from the drawn position corresponding to the groove 32 into a position which corresponds to the groove 33 or the groove 34, the path of the piston becomes 27 and thus the angle of rotation of the table top 15 (Fig.l). enlarged. According to the invention, the angle of rotation and thus the sub-step of the table top are selected by assigning the elevation 37 (FIG. 2) of the bolt 31 to a correspondingly long groove 32 or 33 or 34 of the slot bushing 30. In addition, the threaded bearing bushings 47 and 48 are used simultaneously to clamp the diaphragms 12 and 49, respectively, at their bore diameters.

Von weiterem großen Vorteil ist, daß bei dieser Anordnung die untere, die Tischplatte verriegelnde Membrane 49 mit einer wesentlich größeren wirksamen Kolbenfläche ausgelegt werden kann als die obere Membrane 129 die die Tischplatte nur entriegeln muß. Dieser Vorteil äußert sich in einem geringen Luftverbrauch bei optimal großer Verriegelun#skraft.Another great advantage is that with this arrangement the lower, the tabletop locking membrane 49 with a much larger effective one Piston surface can be designed as the upper membrane 129 which the table top just have to unlock. This advantage manifests itself in a low air consumption optimally large locking force.
