Description

Federprüfmaschine zur gleichzeiigen statischen Prüfung von mehreren Federn Die Erfindung betrifft eine Federprüfinaschine zur statischen Prüfung von Federn.Spring testing machine for simultaneous static testing of several Springs The invention relates to a spring testing machine for static testing of Feathers.

Es ist bereits bekannt, mehrere Federn gleichzeitig mittels einer Federprüfmaschine der statischen Prüfung zu unterwerfen. Während aber bei diesen bekannten Prüfvorrichtungen .die auf die Federn einwirkenden Druckorgane im Maschinengehäuse fest gelagert sind, ist bei der vorliegenden Erfindung ein Differentialgetriebe so angeordnet, daß die einzelnen die zu prüfenden Federn belastenden Druckstempel derart auseinander gezogen werden können, daß sie sich jederzeit in gleichen Abständen untereinander befinden und so die Prüfung von mehreren Federn zugleich ermöglichen, ohne daß auf die Breite der je- weils in Untersuchung befindlichen Federnart besonders Rücksicht genommen zu werden braucht.It is already known to subject several springs to the static test at the same time by means of a spring testing machine. While in these known testing devices .the pressure elements acting on the springs are firmly mounted in the machine housing, in the present invention a differential gear is arranged so that the individual pressure stamps loading the springs to be tested can be pulled apart so that they are always the same Distances from one another and thus enable several springs to be tested at the same time without having to pay particular attention to the width of the type of spring being examined.

In .den Abb. r und 2, die eine schematische Darstellung einer beispielsweisen Ausführung zeigen, ist eine Vorder- und Seitenansicht der Vorrichtung wiedergegeben.In .den Fig. R and 2, which are a schematic representation of an exemplary Show embodiment, a front and side view of the device is shown.

In der Abb. r sind a., b, c und d vier hydraulische Druckzylinder, die in an sich bekannter Weise betätigt werden und deren Stempel auf die Federn e, f, g und la drücken.In Fig. R, a., B, c and d are four hydraulic pressure cylinders which are actuated in a manner known per se and whose stamp presses on the springs e, f, g and la.

Die Druckzylinder a, b, c und d sind in einem Bett i. verschiebbar gelagert. Sie tragen ferner beiderseits \Tocken k, 1, in und n, die durchbohrt und mit Gewinde versehen sind. In die Gewindenocken sind zwei abgestufte Gewindespindeln (l und r eingepaßt. Die einzelnen Gewindestücke haben eine solche Steigung, daß bei einer Drehbewegung mittels der Kurbel s und der Stirnräder u und t die Druckzylinder a, b, c und d jeweils so auseinandergezogen werden, daß ihre Abstände untereinander ständig gleichbleiben.The pressure cylinders a, b, c and d are in a bed i. movably mounted. They also have \ Tocken k, 1, in and n on both sides, which are pierced and threaded. Two stepped threaded spindles (l and r are fitted into the threaded cams. The individual threaded pieces have such a pitch that, during a rotary movement by means of the crank s and the spur gears u and t, the pressure cylinders a, b, c and d are each pulled apart in such a way that their distances from one another constantly remain the same.

Es ist also möglich, in die Vorrichtung verschieden breite Federn, die unter sich gleiche Breite haben, einzulegen und die Druckstempel durch Bewegung von Übertragungsmitteln mittels eines einfachen Handgriffs jeweils. gemeinsam auf diese Breite .einzustellen.It is therefore possible to insert springs of different widths into the device, which have the same width under each other, to insert and the pressure stamp by movement of transmission means by means of a simple handle each. together to set this width.
