Description

Verfahren zur Herstellung des Hohlraumes für elastische Kraftmesser. Gemäß dem Patent 422o87 wird der innere Hohlraum bei elastischen Kraftmessern in der Weise hergestellt, daß der Plattenkörper von dem Rande aus angebohrt wird. Die radial verlaufenden Bohrungen stoßen in der Mitte sternförmig zusammen.Method for producing the cavity for elastic force gauges. According to the 422o87 patent, the inner cavity of elastic force gauges is in manufactured in such a way that the plate body is drilled from the edge. the radial holes meet in the middle in a star shape.

Bei dem Verfahren nach der vorliegenden Erfindung werden die Bohrungen nicht an dem ganzen Umfang ausgeführt. Es werden vielmehr nur einige Bohrlöcher vorgesehen, durch welche dann abwechselnd Fräswerkzeuge vorgetrieben werden, mit denen der Hohlraum ausgearbeitet wird.In the method according to the present invention, the holes not carried out on the whole circumference. Rather, there will only be a few drill holes provided, through which milling tools are then alternately advanced, with which the cavity is worked out.

In der Zeichnung ist die Erfindung dargestellt. Abb. i zeigt einen Längsschnitt, Abb. 2 und 3 geben einen Querschnitt durch den Plattenkörper.The invention is shown in the drawing. Fig. I shows one Longitudinal section, Figs. 2 and 3 give a cross section through the plate body.

Der Kraftprüfer besteht aus zwei Kraftangriffsstellen i und einem Plattenkörper 2, der eine möglichst glatte, flache Höhlung 3 enthalten muß. Die Öffnungen 4, die zur Herstellung der Höhlung notwendig sind, werden nachträglich durch Einsetzen von Paßstücken 5 fest und dicht verschlossen.The force tester consists of two force application points i and one Plate body 2, which must contain a cavity 3 that is as smooth as possible. the Openings 4, which are necessary to produce the cavity, are made afterwards tightly and tightly closed by inserting fitting pieces 5.

Abb. 2 zeigt die Herstellung des Hohlraumes, in dem ein rotierender Fräser 6 eine schwingende Bewegung ausführt. In den Endlagen 7 der schwingenden Bewegung wird der Fräser jedesmal etwas weiter in das Material eingebohrt und alsdann die Schwenkung wiederholt, so daß bei jeder Schwenkung eine weitere Materialfläche 8 ausgearbeitet wird. Ist die Fräsarbeit von der einen Seite aus beendet, so beginnt die Arbeit durch eine der anderen Bohrungen. Auf diese Weise entsteht ein durch Kreisbogen begrenzter Hohlraum. Soll ein vollständig kreisrunder Hohlraum gewonnen werden (Abb. 3), so wird der Fräser g sofort auf seine ganze Tiefe in das Material eingebohrt und dann langsam geschwenkt, wobei nach und nach die Materialflächen io ausgearbeitet werden. Damit die Bewegung der Stirnfläche auf der einen Kreislinie erfolgt, muß der Fräser während der Schwenkung achsial etwas verschoben werden.Fig. 2 shows the production of the cavity in which a rotating Milling cutter 6 performs an oscillating movement. In the end positions 7 of the vibrating Movement, the milling cutter is bored a little further into the material and then the pivot repeats, so that with each pivot an additional material surface 8 is being worked out. Once the milling work has been completed from one side, it begins work through one of the other holes. In this way one is created through Arc delimited cavity. A completely circular cavity should be obtained (Fig. 3), the milling cutter g is immediately inserted into the material to its full depth drilled in and then slowly pivoted, gradually removing the material surfaces io to be worked out. Thus the movement of the face on one circular line takes place, the milling cutter must be axially shifted slightly during the swiveling.

Der in dieser Weise hergestellte Hohlraum wird zweckmäßig nachträglich durch Einlagen wieder verkleinert, um die benötigte Menge an Meßflüssigkeit zu beschränken.The cavity produced in this way is expediently subsequently again reduced in size by inserts in order to limit the required amount of measuring fluid.
