Description
Die Erfindung stellt sich die Aufgabe, eine Überwurfmutter, die über einen mit Außengewinde versehenen geteilten Stangenkopf geschoben wird und ihn dadurch mit einem S anderen Maschinenteil, z. B. einer Kolbenstange, verbindet, in ihrer Lage zu sichern. Diese Aufgabe wird beispielsweise bei Preßluftwerkzeugen gestellt. Bei diesen Werkzeugen ist die Gefahr einer Lockerung derThe object of the invention is to provide a union nut that has an external thread provided split rod head is pushed and thereby S another machine part, z. B. a piston rod, connects, secure in their position. This task is, for example, with compressed air tools posed. With these tools there is a risk of loosening
ίο Mutter infolge der "fortgesetzten Erschütterungen und Stöße, denen das Werkzeug unterworfen ist, besonders groß.ίο mother as a result of the "continued tremors and shocks to which the tool is subjected, particularly large.
Innerhalb der Überwurfmutter wird nach der Erfindung eine geschlitzte Hülse angeordnet, die mit keilförmigen Ansätzen ausgerüstet ist. Die Mutter drückt beim Anziehen gegen diese Hülse und preßt deren keilförmige Ansätze in entsprechende Aussparungen der Teile des erwähnten Stangenkopfes, die hierdurch auseinandergepreßt werden und sich infolgedessen mit ihrem Außengewinde fest gegen das Muttergewinde legen.According to the invention, a slotted sleeve is arranged within the union nut, which is equipped with wedge-shaped lugs. The nut presses against this sleeve when it is tightened and presses it wedge-shaped approaches in corresponding recesses in the parts of the rod head mentioned, which are thereby pressed apart and consequently with their external thread firmly against the nut thread place.
Die Zeichnung zeigt ein. Ausführungsbeispiel der Erfindung, und zwar Fig. 1 die Kupplung geöffnet, Fig. 2 geschlossen. Der geteilte Kopf b, der mit Außengewinde versehen ist, soll mit Hilfe der Überwurfmutter a, die über das Außengewinde geschoben wird, mit der Stange c verbunden werden. In dem Hohlraum der Überwurfmutter ist die Hülse d angeordnet, die mit zwei keilförmigen Ansätzen e versehen und zweckmäßig geschlitzt ausgeführt ist. Beim Anbringen der Kupplung wird zunächst die Mutter α auf die Kolbenstange c gebracht und hierauf die außen kegelförmige Hülse d, so daß die Hülse zwischen den Kopfhälten b und der Mutter liegt. Wird nun die Mutter α auf die .zusammengeklappten Kopfhälften'fr geschraubt, so drückt sie mit ihrer kegelig ausgedrehten Fläche gegen die entsprechende Außenfläche der Hülse. Infolge hiervon legen sich die keilförmigen Ansätze e der Hülse d in die entsprechenden Ausparungen der Kopfhtlften i» (Fig. 2) und drücken sie auseinander. Hierdurch wird das Außengewinde der Kopfhälften b gegen das Muttergewinde gepreßt. Die Mutter wird dadurch in ihrer Lage gesichert. Gleichzeitig bewirkt die Schlitzung der Hülse, daß die Kolbenstange c festgeklemmt -wird; sie wird dadurch gegen Drehung gesichert.The drawing shows a. Embodiment of the invention, namely Fig. 1 the clutch opened, Fig. 2 closed. The split head b, which is provided with an external thread, is to be connected to the rod c with the aid of the union nut a, which is pushed over the external thread. In the cavity of the union nut, the sleeve d is arranged, which is provided with two wedge-shaped lugs e and is expediently slotted. When attaching the coupling, the nut α is first placed on the piston rod c and then the externally conical sleeve d, so that the sleeve lies between the head halves b and the nut. If the nut α is now screwed onto the .folded head halves'fr, it presses with its conically turned surface against the corresponding outer surface of the sleeve. As a result of this, the wedge-shaped extensions e of the sleeve d lie in the corresponding recesses in the head halves i »(FIG. 2) and push them apart. As a result, the external thread of the head halves b is pressed against the nut thread. The mother is thereby secured in her position. At the same time, the slot in the sleeve causes the piston rod c to be clamped; it is thereby secured against rotation.
