Description

Es sind Spannköpfe bekannt, wie solche insbesondere zum Ein- und Herausdrehen von Kesselstehbolzen Verwendung finden, bei denen eine Schraube zum Schließen der S Klemmbacken dient, die dadurch festgestellt wird, daß ein am Stiel des Werkzeugs geführter und unter Federdruck stehender Bügel in Rasten der Gewindebüchse (Mutter der Schraube) federnd eingreift. ίο Die Erfindung besteht darin, daß auf dem Stiel des Gewindekopfes (der Schraube) unterhalb des in den Rasten der Gewindebüchse (Mutter) federnd eingreifenden Bügels ein drehbarer Ring mit schneckenartig ansteigenden Flächen angebracht ist, um mit diesen Flächen bei entsprechender Drehung des Rin-• ges den Bügel aus den Rasten der Gewindebüchse auszuheben und in der ausgehobenen Stellung festzustellen, damit dann der Gewindekopf aus der Gewindebüchse herausgedreht und so der Spannkopf geöffnet werden kann.There are known clamping heads, such as those in particular for turning in and out Boiler studs are used in which a screw is used to close the S clamping jaws, which are thereby fixed is that a guided on the handle of the tool and standing under spring pressure bracket in Locking of the threaded bushing (nut of the screw) engages resiliently. ίο The invention consists in that on the Stalk of the threaded head (of the screw) below the in the notches of the threaded bushing (Nut) resiliently engaging bracket a rotatable ring with spiral-like ascending Surface is attached to with these surfaces with appropriate rotation of the ring • ges to lift the bracket out of the notches of the threaded bushing and in the excavated Determine the position so that the threaded head is then unscrewed from the threaded bushing and so the clamping head can be opened.

In der Zeichnung ist der Spannkopf in Abb. ι im Schnitt, in Abb. 2 in Ansicht, in as Abb. 3 von vorn "gesehen und in Abb. 4 vom Stielende aus gesehen gezeichnet.In the drawing, the clamping head is in Fig. Ι in section, in Fig. 2 in view, in as Fig. 3 seen from the front "and in Fig. 4 from The end of the handle is drawn as seen from the front.

Der kantige Stiel α ist mit einem Gewindekopf b versehen, auf welchem eine Gewindebüchse c aufgeschraubt ist. An dem vorderen Ende ist die Gewindebüchse c kegelig ausgebohrt und dient hier zur Lagerung von Klemmbacken d/die durch Federn e gespreizt gegen die Wandung der Gewindebuchse c gedrückt werden. Wird der Gewindekopf b g^gen die Klemmbacken e geschraubt, so werden diese in der Gewindebüchse c nach vorn verstellt, was zur Folge hat, daß sidh die Klemmbacken e schließen und der Spannkopf dadurch auf dem Arbeitsstück festklemmt. In einem Schlitz / des Stieles α ist ein Bügel g beweglich, der, durch Ausschnitte r j eines Bundes ρ des Gewindekopfes b geführt, j in Rasten h der Gewindebuchse c eingreift i und hierdurch verhütet, daß sich beim Rück- ! wärtsdrehen des Spannkopfes der Gewinde- j kopf b aus der Gewindebüchse c heraus- j schraubt. Denn hierdurch würde sich der | Spannkopf öffnen und von dem Arbeitsstück ; lösen. In dem hohlen Stiel α des Gewindekopfes b ist eine Feder k angebracht, die auf 1 den Bügel g drückt und ihn hierdurch federnd mit den Rasten h der Gewindebuchse c in Eingriff hält. Der Gewindekopf b kann somit, vermöge der federnden Anordnung des Bügels g, frei in die Gewindebüchse c eingeschraubt werden.The angular handle α is provided with a threaded head b on which a threaded bushing c is screwed. At the front end, the threaded bushing c is drilled in a conical shape and is used here to support clamping jaws d / which are pressed, spread apart by springs e, against the wall of the threaded bushing c. If the threaded head b g ^ screwed gen jaws e, they are c in the threaded bushing forward adjusted, which has the consequence that sidh close the jaws e and the clamping head by clamping on the workpiece. In a slot / of the stem α a bracket g is movable, which, guided through cutouts r j of a collar ρ of the threaded head b , j engages in notches h of the threaded bushing c and thereby prevents the rear! Turning the clamping head upwards unscrews the threaded j head b from the threaded bushing c . Because this would result in the | Open the clamping head and remove the workpiece; to solve. In the hollow stem α of the threaded head b , a spring k is mounted, which presses on 1 the bracket g and thereby resiliently holds it in engagement with the notches h of the threaded bushing c. The threaded head b can thus, by virtue of the resilient arrangement of the bracket g, be screwed freely into the threaded bushing c.

Unterhalb des Bügels g· ist nun in einer Vertiefung i des Gewindekopfes b ein drehbarer Ring 0 gelagert, der mit zwei schnekkenartig ansteigenden Flachen I versehen ist. Wird der Ring 0 so eingestellt, daß die höchsten Punkte der Flächen I unterhalb des Bügels §■ zu stehen kommen, so ist dieser aus den Rasten h der Gewindebüchse c ausgelöst, und der Gewindekopf b kann aus der Gewindebüchse c herausgeschraubt werden, womit der Spannkopf geöffnet wird. Damit der Ringo in der oben beschriebenen Stellung feststeht, sind an der Unterseite des Bügels g Nasen ni angebracht, die in entsprechende Kerben η des Ringes 0 eingreifen und in diesen durch die federnde Anordnung des Bügels g gehalten werden.Below the bracket g, a rotatable ring 0 is now mounted in a recess i of the threaded head b , which ring is provided with two surfaces I that rise in the manner of a screw. If the ring 0 is set so that the highest points of the surfaces I come to stand below the bracket § ■, this is released from the notches h of the threaded bushing c , and the threaded head b can be screwed out of the threaded bushing c , whereby the clamping head is opened. So that the ring is fixed in the position described above, noses ni are attached to the underside of the bracket g , which engage in corresponding notches η of the ring 0 and are held in these by the resilient arrangement of the bracket g .

Beim Gebrauch des Spannkopfes wird auf den Stiel α des Gewindekopfes b ein Hebel gesetzt und mit diesem der Spannkopf nach der einen oder der anderen Richtung gedreht, je nachdem das Arbeitsstück festgedreht oder gelöst werden soll. Damit hierbei die Klemmbacken d auf» dem Arbeitsstück nicht gleiten, sind ihre Greifflächen gezahnt.When using the clamping head, a lever is placed on the handle α of the threaded head b and with this the clamping head is rotated in one or the other direction, depending on whether the workpiece is to be tightened or loosened. So that the clamping jaws d do not slide on the work piece, their gripping surfaces are toothed.
