Die Erfindung betrifft ein Meßinstrument für die Wandstärken von Drehkörpern, beispiels-The invention relates to a measuring instrument for the wall thicknesses of rotating bodies, for example
, weise gewölbte Böden von Sprenggeschossen. Die bisher gebräuchlichen Meßinstrumente, bei denen der Drehkörper auf einen besonderen Meßdorn drehbar aufgesetzt wurde, gestatteten eine Prüfung der Wandstärke nur an einer einzigen Stelle bzw. auf einem bestimmten Kreise. Von diesem Prüfungsergebnis ohne, wise arched bottoms of explosive projectiles. The previously used measuring instruments at which the rotating body was rotatably placed on a special measuring mandrel, allowed a test of the wall thickness only at a single point or on a specific one Circles. From this test result without

Platzen des Sprenggeschosses verursacht.Caused the explosive projectile to burst.
Die Erfindung erweitert den Meßbereich des Meßinstrumentes dahin, daß beispielsweise jede beliebige Stelle des Geschoßbodens auf ihre Wandstärke geprüft werden kann. Der Erfindung gemäß ist das mit zwei gegenüberstehenden Meßtastern versehene Meßinstrument um einen im Meßdorn gelagerten Zapfen drehbarangeordnet. The invention extends the measuring range of the measuring instrument so that, for example, each Any point on the floor of the storey can be checked for wall thickness. The invention according to the measuring instrument provided with two opposing measuring probes is arranged to be rotatable about a pin mounted in the measuring mandrel.
Die Zeichnung veranschaulicht ein Ausfünrungsbeispiel der Erfindung.The drawing illustrates an exemplary embodiment the invention.
Auf einer Platte 2 ist ein Meßdorn 1 befestigt, auf dem der zu prüfende Hohlkörper, im vorliegenden Falle eine Wurfgranate, drehv bar aufgesetzt ist. Die Wandstärke des gewölbten Granatenbodens wird mittels der einander gegenüberstehenden Meßtaster 4 und 5 geprüft, die an ihrer Spitze gehärtete Stahlkugeln frei drehbar tragen. Der Taster 4 ist um den Zapfen 6, der im Meßdorn 1 gelagert ist, drehbar angeordnet. Der Meßtaster 5 wird von einem Schenkel 7 gehalten, der mit dem Taster 4 gelenkig verbunden ist, so daß der Taster 5 zum Auf- und Absetzen der Granate 3 auf dem Meßdorn 1 zur Seite geschwenkt werden kann. Der Taster 5 ist in Richtung der die beiden Tasterspitzen verbindenden Geraden verschieblich angeordnet. Seine Anschläge werden auf einen Zeiger 8 übertragen, der auf dem Schenkel 7 das Meßergebnis anzeigt und die Änderungen der Wandstärke kenntlich macht. Mit dem Griff 9 wird das Meßinstrument um den Zapfen 6 geschwenkt. Da die Granate 3 auf dem Meßdora 1 frei drehbar ist, kann somit der ganze Boden der Granate der Prüfung unterzogen werden.On a plate 2, a plug gauge 1 is fixed on which the to be tested is mounted hollow bodies, in this case a throwing grenade, v rotating bar. The wall thickness of the arched grenade base is checked by means of the opposing measuring probes 4 and 5, which carry hardened steel balls freely rotatable at their tips. The button 4 is rotatably arranged around the pin 6, which is mounted in the measuring mandrel 1. The probe 5 is held by a leg 7 which is hingedly connected to the probe 4 so that the probe 5 can be pivoted to the side for placing and removing the grenade 3 on the mandrel 1. The button 5 is arranged displaceably in the direction of the straight line connecting the two button tips. Its attacks are transferred to a pointer 8, which shows the measurement result on the leg 7 and shows the changes in the wall thickness. The measuring instrument is pivoted about the pin 6 with the handle 9. Since the grenade 3 is freely rotatable on the measuring dora 1, the entire base of the grenade can be subjected to the test.
