Description

Reitstock, bei welchem der Körner hydraulisch angepreßt wird Die Erfindung betrifft eine Weiterausbildung des durch Patent 508 5a6 geschützten Reitstockes, bei welchem in die den Körner verschiebende Vorrichtung ein nachgebendes Druckmittel eingeschaltet ist. Als Druckmittel soll vorzugsweise Preßflüssigkeit verwendet werden.Tailstock in which the grain is pressed hydraulically The invention relates to a further development of the tailstock protected by patent 508 5a6, in which a yielding pressure medium is switched into the device which moves the grain. Pressing fluid should preferably be used as the pressure medium.

Nach der zusätzlichen Erfindung ist nun an die Druckkammer für die Preßflüssigkeit im Pinolengehäuse ein Luftkissen angeschlossen. Bei Reitstöcken, welche mit einer durch eine Pumpe erzeugten oder aus einer besonderen Leitung stammenden Preßflüssigkeit gespeist werden, ist das Luftkissen zwischen Druckkammer und Druckregler bzw. Überlastungsventil angeordnet. Das Luftkissen hat die Wirkung, daß kurze Drucksteigerungen z. B. durch Erschütterungen beim Schruppen bis zu der durch das Überlastungsventil festgelegten Druckgrenze unschädlich gemacht werden. Das Überlastungsventil braucht nicht anzusprechen und einen Druckabfall herbeiführen, welcher mit dem Abklingen der Drucksteigerung wieder ausgeglichen werden muß. Auch kommt bei Reitstöcken, bei welchen der Druck durch einen Verdränger erzeugt wird, die sonst hinter dem Verdränger erforderliche Feder in Fortfall, so d'aß der Ver'dränger und die Druckspindel aus einem Stück angefertigt werden können.According to the additional invention is now to the pressure chamber for Pressing fluid connected to an air cushion in the quill housing. With tailstocks, which come from a line generated by a pump or from a special line Pressing liquid are fed, is the air cushion between the pressure chamber and pressure regulator or overload valve arranged. The air cushion has the effect of brief increases in pressure z. B. by vibrations during roughing up to the by the overload valve specified pressure limit can be rendered harmless. The overload valve needs not to address and cause a pressure drop, which with the subsiding the pressure increase must be compensated for again. Also comes with tailstocks, in which the pressure is generated by a displacer, which is otherwise behind the Displacer required spring in omission, so there was the displacer and the pressure spindle can be made from one piece.

Die Zeichnung veranschaulicht die Erfindung an zwei Ausführungsbeispielen. Abb. i zeigt einen Reitstock im Schnitt, bei welchem die Preßflüssigkeit mittels einer besonderen Leitung zugeführt wird.The drawing illustrates the invention using two exemplary embodiments. Fig. I shows a tailstock in section, in which the press fluid means is fed to a special line.

Abb.2 stellt einen Reitstock im Schnitt dar, bei dem der Flüssigkeitsdruck durch einen Verdränger erzeugt wird.Fig.2 shows a cross-section of a tailstock where the fluid pressure is generated by a displacer.

An die Druckkammer z im Pinolengehäuse ist der Behälter 2 angeschlossen, in welchem das Luftkissen sich befindet. Der Behälter steht durch den Hahn 3 mit der Außenluft in Verbindung.The container 2 is connected to the pressure chamber z in the sleeve housing, in which the air cushion is located. The container stands with the tap 3 the outside air in connection.

Bei dem in Abb. i gezeigten Ausführungsbeispiel ist der Behälter 2 mit dem Luftkissen zwischen dem Überlastungsventil, zu dem die Rohrleitung 4 führt, und der Druckkammer angeordnet. Der Hahn 5 ermöglicht es, die Verbindung nach der Druckkammer abzusperren.In the embodiment shown in FIG with the air cushion between the overload valve to which the pipe 4 leads, and the pressure chamber arranged. The tap 5 enables the connection after the Shut off pressure chamber.
