Description
Rundtisch mit hydraulischer Klemmung Es sind Rundtische für Werkzeugmaschinen bekannt, die schritt-1 weise weitergeschaltet und nach jedem Teilschritt festgeklemmt werden, damit die Bearbeitung des oder der Werkstücke im Stillstand des) Tisches erfolgen kann. Die Klemmung dieser Rundtische erfolgt im allgemeinen durch eine oder mehrere auf den äußeren Tischumfang oder in der Nähe desselben einwirkende Klemmvorrichtungen, die entweder mechanisch oder hydraulisch betätigt werden. Der Nachteil dieser Art Klemmung besteht darin, daß die Klemmvorrichtungen nur an einzelnen Punkten angreifen und daher zur sicheren Festlegung des Tisches eine sehr große Kraft erfordern, wobei außerdem leicht ein Verziehen des Tisches antreten kann.Rotary table with hydraulic clamping These are rotary tables for machine tools known, the step-1 progressed and clamped after each sub-step so that the machining of the work piece (s) while the table is stationary can be done. These rotary tables are generally clamped by a or several acting on or in the vicinity of the table's outer circumference Clamping devices that are operated either mechanically or hydraulically. Of the The disadvantage of this type of clamping is that the clamping devices are only used on individual Attack points and therefore a very large one to secure the table Require force, and the table can also easily warp.
Gemäß der Erfindung werden diese Nachteile dadurch behoben, daß in einer Ringnut des ortsfesten Teiles des Rundtisches eine Nutringmanschette so angeordnet ist, daß sie mit ihrer Vorderseite auf den Drehteil des Rundtisches einwirkt und auf ihrer Rückseite durch ein Druckmittel beaufschlagt werden kann.According to the invention, these disadvantages are eliminated in that in an annular groove of the stationary part of the rotary table a grooved ring collar so arranged is that it acts with its front on the rotating part of the rotary table and can be acted upon by a pressure medium on its rear side.
Hierdurch wird erreicht, daß der Klemmdruck sich gleichmäßig über eine geschlossene Ringzone des Tisches verteilt, so daß auch bei Anwendung mäßiger Drücke eine gute Festlegung des Tisches in jeder gewünschten Stellung erreicht wird. Von besonderem Nert ist dabei, daß dieses Ziel mit sehr einfachen und dadurch billigen Mitteln erreicht wird.This ensures that the clamping pressure is evenly spread over distributed a closed ring zone of the table, so that even when used more moderate Press a good fixation of the table in any desired position is achieved. What is particularly important is that this goal is very simple and therefore approve Funds is achieved.
Um die Klemmwirkung noch zu verbessern, empfiehlt es sich, in entsprechenden
Ringnuten des ortsfesten Teiles des Rundtisches zwei mit der Rückseite gegeneinander
zeigende und mit ihren Vorderseiten gegen den Drehteil des Rundtisches
Bei gleicher Bemessung der Nutringbreiten heben sich dann die auf den Tisch zur Auswirkung kommenden hydraulischen Drücke auf, so daß durch die Klemmung keine zusätzliche Belastung der Tischlagerung eintritt. Es ist aber auch möglich, der unteren Nutringmanschette eine etwas größere radiale Breite zu geben als der oberen, so daß die Klemmung zu einer geringen nach unten gerichteten Kraftkomponente führt.With the same dimensioning of the groove ring widths, they cancel each other out the table to the effect coming hydraulic pressures, so that by the clamping there is no additional load on the table support. But it is also possible to give the lower U-ring collar a slightly larger radial width than the upper, so that the clamping to a small downward force component leads.
Um jede Abnutzung der Nutringmanschetten zu vermeiden, kann zwischen diesen und der Anlagefläche des Drehteiles des Rundtisches ein Stahlblech angeordnet werden. Das Blech bzw. die Bleche können ferner zur Erhöhung der Reibung auf der zum Drehteil hin gelegenen Seite aufgerauht'oder mit einem Bremsbelag versehen werden.In order to avoid any wear and tear on the U-ring sleeves, between this and the contact surface of the rotating part of the rotary table, a sheet steel is arranged will. The sheet or sheets can also increase the friction on the the side facing the turned part is roughened or provided with a brake lining.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung als Schnitt durch eine Hälfte des Rundtisches dargestellt.In the drawing, an exemplary embodiment of the invention is shown in section represented by one half of the round table.
Auf dem ortsfesten Untergestell 1 ist mittels des Drahtkugellagers 2 der eigentliche Tisch 3 um die der Mittellinie 4 entsprechende Achse drehbar gelagert. Der Tisch 3 ist mit einem ringförmigen Körper 5 verschraubt, der in der Nähe seines oberen Endes fest mit dem inneren Laufring 15 des Kugellagers 2 verbunden ist und in der Nähe seines unteren Endes das Schneckenrad 6 und die Teilscheibe 7 trägt.On the stationary underframe 1 is by means of the wire ball bearing 2 the actual table 3 is rotatably mounted about the axis corresponding to the center line 4. The table 3 is screwed to an annular body 5, which in the vicinity of his upper end is firmly connected to the inner race 15 of the ball bearing 2 and in the vicinity of its lower end the worm wheel 6 and the indexing disk 7 carries.
Das Rad 6 dient-zum Antrieb des Tisches 3 über eine nicht dargestellte Schnecke. Die mit Rasten 7a versehene Teilscheibe 7 arbeitet in bekannter Weise mit einem ebenfalls nicht dargestellten Indexbolzen zusammen.The wheel 6 is used to drive the table 3 via a not shown Slug. The indexing disk 7 provided with notches 7a works in a known manner together with an index bolt, also not shown.
Der ringförmige Körper 5 ist so ausgebildet, daß er zusammen mit der Tischunterseite einen weiteren Ringkörper 8 zangenartig umgreift. Der letztere, der durch Schrauben 9 fest mit dem ortsfesten Untergestell 1 verspannt ist, enthält zwei zu seinen Oberflächen hin offene Ringnuten, in die Nutringmanschetten 10 und 11 so eingesetzt sind, daß sie mit ihrer Rückseite gegeneinander zeigen. Beiderseits des Ringkörpers 8 sind ebenfalls ringförmige Bleche 12 und 13 so eingespannt, daß sie die Ringnuten überdecken. Die Nutringmanschetten 10 und 11 wirken daher mit ihrer Vorderseite nicht unmittelbar auf den drehbaren Teil 3, 5 ein, sondern über die Bleche 12 und 13. Zur Rückseite der Nutringmanschetten 10 und 11 führt eine gemeinsame, bei 1. 4 angedeutete Leitung, über die ein Druckmittel, vorzugsweise Drucköl, zugeführt werden kann.The annular body 5 is formed so that it together with the Underside of the table encompasses a further ring body 8 like pliers. The latter, which is clamped firmly to the stationary underframe 1 by screws 9, contains two ring grooves open towards its surfaces, in the U-ring collars 10 and 11 are inserted so that they point with their backs against each other. On both sides of the ring body 8 are also ring-shaped sheets 12 and 13 clamped so that they cover the ring grooves. The u-ring sleeves 10 and 11 work therefore with its front side not directly on the rotatable part 3, 5, but over the sheets 12 and 13. To the rear of the U-ring collars 10 and 11 leads a common line indicated at 1. 4, via which a pressure medium, preferably Pressure oil, can be supplied.
Um den Tisch in der jeweils gewünschten Lage zu verriegeln, wird die Leitung 14 an die Druckmittelquelle, z. B. eine Zahnradpumpe, angeschlossen. Das Druckmittel gelangt dann über diese Leitung gleichzeitig zu den Rückseiten der Nutringmanschetten 10 und 11, so daß diese mit ihren Vorderseiten über die Bleche 12,13 einen entsprechenden Druck auf den drehbaren Teil 3, 5 ausüben. Wie die Abbildung erkennen läßt, ist die untere Nutringmanschette 11 etwas breiter als die obere 10. Es entsteht daher eine nach unten gerichtete Kraftkomponente, die den Tisch 3 zusätzlich auf seinen Sitz drückt.To lock the table in the required position, the Line 14 to the pressure medium source, e.g. B. a gear pump connected. That Pressure medium then reaches the rear of the U-ring sleeves via this line at the same time 10 and 11, so that these with their front sides over the sheets 12,13 a corresponding Apply pressure to the rotatable part 3, 5. As the figure shows, is the lower U-ring collar 11 is slightly wider than the upper 10. It is therefore created a downward force component that the table 3 in addition to his Seat presses.
