Description
Das Einsetzen und insbesondere das Herausnehmen von Paßschrauben, die an ihrem Umfang ein Außengewinde haben und damit durch das Gewinde des Sicherungssockels hindurchgeschraubt werden müssen, kann ohne besondere Werkzeuge schwer ausgeführt werden. Als AngriffssteUe für das Werkzeug dient am zweckmäßigsten das Innere der Paßbohrung. Nach der Erfindung wird die Paßbohrung aa dem einen Ende nach außen kegelförmig erweitert. Dadurch ist die Möglichkeit geschaffen, zum Einsetzen und Herausschrauben von Paßhülsen ein Werkzeug zu verwenden, das aus zwei zangenförmig sich spreizenden Hebeln besteht, denen Bewegung durch eine Schraubenspindel erzwungen wird. Auf der Zeichnung ist in Abb. 1 ein Schnitt durch einen Sicherungssockel mit eingeführtem Werkzeug und Paßhülse dargestellt.The insertion and in particular the removal of fitting screws that are attached to your Circumference have an external thread and thus screwed through the thread of the fuse base can be difficult to do without special tools. The interior of the fitting bore is most expediently used as the attack control for the tool. According to the invention, the fitting bore aa is tapered outwardly at one end expanded. This creates the possibility of inserting and unscrewing of fitting sleeves to use a tool that consists of two pliers spreading levers, which movement is forced by a screw spindle. On the drawing in Fig. 1 is a section through a fuse base with inserted Tool and adapter sleeve shown.
ao Abb. 2, 3, 4 zeigen verschiedene Paßhülsen im Schnitt, und Abb. 5 zeigt das Werkzeug in Ansicht. jao Figs. 2, 3, 4 show various fitting sleeves in section, and Fig. 5 shows the tool in Opinion. j
Die Paßbohrungen haben an dem einen j Ende eine nach außen kegelförmige Erweiterung i. Hiergegen legen sich die beiden sich nach außen spreizenden Hebel 2 und 3 des Werkzeuges. Die Bewegung der Hebel erfolgt durch eine Schraubenspindel 4, die im oberen Teil des Werkzeuges gelagert ist und sich mit ihrem vorderen Ende 5 gegien die Hebel legt und sie beim Einschrauben auseinandertreibt. Die Paßhülsen stützen sich gegen 'eine Hülse 6 am Werkzeug. Dadurch ist die richtige Einführung des Werkzeuges und das zuverlässige Erfassen der Paßhülse gewährleistet. Selbstverständlich ist es mögEch, mit dem Werkzeug auch Paßhülsen zu fassen, deren Paßbohrung nicht nach außen kegelförmig erweitert ist, wenn auch in diesem Fall die Festhaltung nicht so zuverlässig ist.The fitting bores have an outwardly conical expansion at one end i. Against this, the two outwardly spreading levers 2 and 3 of the Tool. The lever is moved by a screw spindle 4 in the upper Part of the tool is stored and with its front end 5 against the lever sets and drives them apart when screwing in. The fitting sleeves are supported against a sleeve 6 on the tool. This is the correct introduction of the tool and that is reliable Capturing the fitting sleeve guaranteed. Of course it is possible with the tool also to take fitting sleeves whose fitting bore does not expand conically towards the outside is, even if in this case the detention is not so reliable.
