Description

Es kommt in der Technik sehr häufig vor, daß irgendeine Kraft auf Toleranzen zu messen ist. Dabei muß festgestellt werden, ob die zu messende Kraft einen Mindestbetrag nicht untreschreitet und einen lli.chstbetrag nicht überschreitet. Die vorliegende Erfindung betrifft eine Einrichtung zur Durchführung derartiger Toleranzmessungen Sie ist im folgenden beispielsweise beschrieben und in den Abb. 1 und 2 beispielsweise und schematisch dargestellt. It is very common in technology that some force occurs Tolerances is to be measured. It must be determined whether the force to be measured does not fall short of a minimum amount and does not exceed a minimum amount. The present invention relates to a device for performing such Tolerance measurements It is described below, for example, and shown in Fig. 1 and 2 are shown schematically and by way of example.

In den Abbildungen bedeutet I das Gehäuse der Meßeinrichtung. Mit 2 ist eine bügelförmige Meß'-feder bezeichnet. An dem einen Schenkel dieser Meßfeder ist ein Fühlstiftmeßgerät 3 angebracht, an ihrem anderen Schenkel eine Feineinstellschraube 4. Die Meßfeder 2 ist in dem Gehäuse 1 zwischen einer im Gehäuse befestigten Schneide 5 und einer zweiten Schneide 6 gelagert, welch letztere ui dem Druckstück 7 angeordnet ist das die zu messende Kraft, auf die Meßfeder überträgt. Das Druckstück 7 kann zur Erhöhung der Meßgenauigkeit im Gehäuse in all sich bekannter Weise in Kugellagern geführt sein. Außer der Schneide 5 ist im Gehäuse die Schneide 8 befestigt, die den Drehpunkt für den Hebel 9 bildet. All dem aus dem Gehäuse herausragenden Ende des Hebels 9 ist ein Gewichtsträger 10 angehängt. In the figures, I means the housing of the measuring device. With 2 is a bow-shaped measuring spring. On one leg of this measuring spring a Fühlstiftmeßgerät 3 is attached, on its other leg a fine adjustment screw 4. The measuring spring 2 is in the housing 1 between a cutting edge fixed in the housing 5 and a second cutting edge 6, which latter is arranged on the pressure piece 7 this is the force to be measured, transferred to the measuring spring. The pressure piece 7 can to increase the measurement accuracy in the housing in a known manner in ball bearings be led. Except for the cutting edge 5, the cutting edge 8 is attached in the housing forms the fulcrum for the lever 9. All the end protruding from the case a weight carrier 10 is attached to the lever 9.

Beim Gebrauch der neuartigen Meßeinrichtung geht man nie folgt vor. Auf den Gewichtsträger 10 werden so viel Gewichte ii aufgelegt. daß an der Schneide 6 auf die Meßfeder der mindestens zu verlangende Betrag der zu messenden Kraft übertragen ird. Dabei ergibt sich ein Ausschlag des Zeigers 1 2 des Fühlstiftmeßgerätes, der durch Anstellen der Toleranzmarke 1 3 fixiert wird. Alsdann wird zu den Gewichten 11 das Toleranzgewicht 14 gelegt, so daß auf die Meßfeder der höchstens zulässige Betrag der zu messenden Kraft wirkt. Der dabei sich einstellende Zeigerausschlag wird durch Anstellen der Toleranzmarke 15 ebenfalls fixiert. Nachdem schlieblirit noch durch Umlegen des Nockens 16 der Gewichtshebel 9 von der Meßfeder abgeschaltet worden ist, ist die Einrichtung fertig zur Toleranzmcssung, bei der. man anstatt der Gewichte 11 und 14 die zu messende Kraft auf die Meßfeder wirken läßt und feststellt, ob der Zeiger des Fühlstiftmeßgerätes innerhalb des durch die Toleranzmarken 13 und 1 5 abgegrenzten Toleranzfeldes steht. When using the new type of measuring device, one never proceeds as follows. As many weights ii are placed on the weight carrier 10. that at the cutting edge 6 Transfer the minimum amount of force to be measured to the measuring spring earth. This results in a deflection of the pointer 1 2 of the Fühlstiftmeßgerätes, the is fixed by adjusting the tolerance mark 1 3. Then it becomes the weights 11 placed the tolerance weight 14 so that the maximum permissible The amount of force to be measured is effective. The resulting pointer deflection is also fixed by adjusting the tolerance mark 15. After closing still switched off by turning the cam 16 of the weight lever 9 from the measuring spring has been, the device is ready for tolerance measurement in which. one instead of the weights 11 and 14 let the force to be measured act on the measuring spring and determine whether the pointer of the Fühlstiftmeßgerätes is within the range indicated by the tolerance marks 13 and 1 5 delimited tolerance field.

Abb. 1 stellt die Einrichtung heim Einstellen des Toleranzfeldes dar, Abb. 2 beim Messen. Fig. 1 shows the facility for setting the tolerance field Fig. 2 when measuring.
