Description
Die Erfindung geht aus von einer Vorrichtung zur Prüfung von Druck federn.The invention relates to a device for testing pressure feathers.
Der Schiefstand der Federenden wird bisher in ungespanntem Zustand durch mechanische und optische Verfahren geprüft. Eine Aus sage über das Schiefstandsverhalten der Feder unter Last ist nicht möglich.The inclination of the spring ends is so far unstressed Condition checked by mechanical and optical methods. An out is not about the misalignment behavior of the spring under load possible.
Die erfindungsgemäße Vorrichtung zur Prüfung von Druckfedern mit den kennzeichnenden Merkmalen hat demgegenüber den Vorteil, daß eine schnelle, genaue und objektive Messung des Schiefstandes der Feder enden in gespanntem und ungespanntem Zustand möglich ist.The inventive device for testing compression springs with the distinguishing features has the advantage that a Fast, accurate and objective measurement of the spring's misalignment ends in a tensioned and untensioned condition is possible.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention result from the Subclaims.
Ein Ausführungsbeispiel der Erfindung ist in der nachfolgenden Be schreibung und Zeichnung wiedergegeben. Letztere zeigt in Fig. 1 in vereinfachter Darstellung eine Ansicht einer Federprüfvorrichtung, in Fig. 2 einen perspektivische Ansicht der Kardanaufhängung, in den Fig. 3 und 4 Seitenansicht und Draufsicht eines Einzelteils.An embodiment of the invention is shown in the following description and drawing Be. The latter shows in Fig. 1 in a simplified representation a view of a Federprüfvorrichtung, in Fig. 2 is a perspective view of the gimbal in FIGS. 3 and 4 are side and top views of an individual part.
Die Vorrichtung weist eine Grundplatte 10 auf, die über mehrere senkrechte Säulen 11 mit einer Jochplatte 12 verbunden ist. Auf der Grundplatte 10 ist ein Tragrahmen 13 höhenverschiebbar angeordnet. Am Tragrahmen ist eine Auflage 14 kardanisch gelagert, und zwar in einem Koppelkreuz 15, dessen zwei sich kreuzende Achsen 15 A und 15 B im Tragrahmen 13 gelagert sind. Die Achse 15 A nimmt einen Dreh winkelgeber 17 auf, während die Achse 15 B, welche die Auflage 14 aufnimmt, mit einem Drehwinkelgeber 18 versehen ist. Auf der Auflage 14 liegt das untere Federende einer Druckfeder 20 (Prüfling) an.The device has a base plate 10 which is connected to a yoke plate 12 via a plurality of vertical columns 11 . On the base plate 10 , a support frame 13 is vertically displaceable. A support 14 is gimbal-mounted on the support frame, specifically in a coupling cross 15 , the two crossing axes 15 A and 15 B of which are supported in the support frame 13 . The axis 15 A receives a rotary encoder 17 , while the axis 15 B , which receives the pad 14 , is provided with a rotary encoder 18 . The lower spring end of a compression spring 20 (test specimen) lies on the support 14 .
Die obere kardanische Aufhängung ist identisch ausgebildet. Sie be findet sich in einem Tragrahmen 21, welcher verschiebbar in der Jochplatte 12 angeordnet ist und auf welche die Prüflast einwirkt. Die kardanische Aufhängung hat ein Koppelkreuz 22 mit den zwei sich kreuzenden Achsen 22 A und 22 B, an denen jeweils ein Drehwinkelgeber 23, 24 angeordnet ist. Die Achse 22 B ist mit der oberen Auflage drehbar verbunden. An der oberen Auflage 25 liegt das obere Feder ende der Druckfeder 20 an.The upper gimbal is identical. It be found in a support frame 21 which is slidably disposed in the yoke plate 12 and on which the test load acts. The gimbal has a coupling cross 22 with the two crossing axes 22 A and 22 B , on each of which an angle encoder 23 , 24 is arranged. The axis 22 B is rotatably connected to the upper support. The upper spring end of the compression spring 20 bears against the upper support 25 .
Zur genauen Positionierung der zu prüfenden Feder sind auf den Auf lagen 14, 15 - in den Fig. 3 und 4 ist die Auflage 14 dargestellt - verstellbare Backen 26 angeordnet. Der Schiefstand der Enden der Druckfeder 20 wird auf die Platten 14, 25 übertragen. Die ent sprechende Verdrehung der Auflagen 14, 25 - soweit die Federenden schief sind - wird durch die Drehwinkelgeber 17, 18 einem Rechner übertragen und ausgewertet. Der Tragrahmen 13 ist zum Längenaus gleich der verschiedenen Federn höheneinstellbar. For exact positioning of the spring to be tested on the layers 14 , 15 - in FIGS. 3 and 4, the pad 14 is shown - adjustable jaws 26 are arranged. The obliquity of the ends of the compression spring 20 is transferred to the plates 14 , 25 . The corresponding rotation of the pads 14 , 25 - as far as the spring ends are crooked - is transmitted and evaluated by the angle encoder 17 , 18 a computer. The support frame 13 is adjustable in length to equal the various springs.
Mit der beschriebenen Vorrichtung können gleichzeitig beide Feder enden auf Schiefstand geprüft werden. Weiterhin ist eine Messung der Abweichungen von der zylindrischen Form möglich. Die Meßebene be findet sich jeweils in Lagermitte. Die Auswertung der Abweichung in Größe und Richtung erfolgt durch Rechnereinsatz. Die Auflagen 14, 25 im Meßbereich sind massenausgeglichen, dadurch ergeben sich keine Meßwerteverfälschungen. Zweckmäßig ist eine Blockiereinrichtung für den unteren Tragrahmen 13.With the device described, both ends of the spring can be checked for inclination simultaneously. It is also possible to measure the deviations from the cylindrical shape. The measuring plane is located in the middle of the warehouse. The deviation in size and direction is evaluated using a computer. The supports 14 , 25 in the measuring range are mass-balanced, so there are no falsifications of the measured values. A blocking device for the lower support frame 13 is expedient.
