Description

Vorrichtung zum Prüfen der Spannkraft von Kontaktfedern. Die Vorrichtung, welche Gegenstand der Erfindung ist, dient zum Prüfen der Spannkraft von Kontaktfedern, z. B. der im Ferns prechbetriebe verwendeten Abfrageklinken o. dgl. Sie wird nach Art der bekannten zwischen die Abfrageklinken einzuschiebenden Verb*ndungsstöpsel gehandhabt und eignet sich deshalb besonders zum Ermitteln der Kraft solcher Federn, die bereits eingebaut sind und aus betriebstechnischen Gründen von Zeit zu Zeit oder nach irgendwelchen Vorkommnissen auf ihre Zuverlässigkeit hin untersucht werden müssen.Device for testing the clamping force of contact springs. The device, which is the subject of the invention, is used to test the clamping force of contact springs, z. B. the interrogation jacks used in Ferns prechbetriebe o. The like. She is after Type of known connecting plug to be inserted between the interrogation latches handled and is therefore particularly suitable for determining the force of such springs, which are already installed and from time to time for operational reasons or be examined for reliability after any occurrences have to.

Die Vorrichtung ist im wesentlichen ein mit einem Meßwerk ausgerüsteter Stöpsel.The device is essentially one equipped with a measuring mechanism Plug.

Die Zeichnung ist eine Schnittdar:.tellung eines Ausführungsbeispiels der Erfindung in ihrer Anwendung zum Prüfen der Federkraft einer Abfrageklinke.The drawing is a sectional view of an exemplary embodiment of the invention in its application for testing the spring force of an interrogation pawl.

Diese ist mit f bezeichnet, der vor ihr liegende Rahmenteil mit h, dessen Öffnung, durch welche sonst der bekannte Verbindungsstöpsel eingeführt wird, mit i.This is denoted by f, the frame part in front of it with h, its opening, through which the known connecting plug is otherwise inserted, with i.

In diese Öffnung wird auch der den Gegenstand der Erfindung bildende Prüfstöpsel eingesetzt, wenn ermittelt werden soll, ob die Klinke f noch die erforderliche Federkraft hat.In this opening is also the subject of the invention Test plug used when it is to be determined whether the pawl f still has the required Has spring force.

Das Gehäuse a des Prüfstöpsels enthält eine gezahnte Welle c und eine im Eingriff mit dieser stehende Zahnstange e, die von einer an der Gehäusewand befestigten Feder b getragen wird. Die Feder b ragt mit einem Kopf g durch eine Öffnung der Stöpselwand. Die Welle c trägt einen Zeiger d, welcher zu einer (nicht dargestellten) Kreisteilung gehört. Der den Zeiger d und die Kreisteilung umschließende Teil des Gehäuses a kann als Griff dienen.The housing a of the test plug contains a toothed shaft c and a in engagement with this standing rack e, which is fastened by one to the housing wall Spring b is worn. The spring b protrudes with a head g through an opening of the Plug wall. The shaft c carries a pointer d, which leads to a (not shown) District division heard. The part of the that encloses the pointer d and the division of a circle Housing a can serve as a handle.

Wird der Prüfstöpsel in die Öffnung i eingeführt, so trifft der Kopf g der Feder b gegen die Klinke f. Die Feder b wird durch die Klinke f je nach deren Spannkraft zurückgedrückt und dreht so rrttels der Zahnstange e die Welle c und mithin den Zeiger d über seine Kreisteilung. Der Ausschlag des Zeigers läßt erkennen, ob die Klinke f noch die nötige Federkraft hat.If the test plug is inserted into the opening i, the head g of the spring b hits the pawl f. The spring b is pushed back by the pawl f depending on its tensioning force and thus rotates the shaft c and consequently the pointer d by means of the rack e about his district division. The deflection of the pointer shows whether the pawl f still has the necessary spring force.

In ähnlicher Weise kann die Vorrichtung zum Messen der Spannkraft anderer Kontaktfedern benutzt werden.In a similar way, the device for measuring the clamping force other contact springs can be used.

Die Drehung der Welle c kann elektrisch nach einem von ihr entfernten Orte übertragen werden, s o daß die Ablesung unabhängig von dem Prüforte erfolgen kann.The rotation of the shaft c can be electrical according to a remote from it Places are transferred, so that the reading take place independently of the test location can.
