Description
Einrichtung zum Messen des Flankendurchmessers von Gewinden Gegenstand des Hauptpatents ist eine Einrichtung zum Messen des Flankendurchmessers von Gewinden mittels eines über das Gewinde zu streifenden Kugelkäfigs, in dem Meßkugeln lose gefaßt sind in Verbindung mit zylindrisch abgestuften oder kegeligen Ringen bzw. Bolzen. Die zusätzliche Erfindung erweitert die Anwendungsmöglichkeit solcher Kugelkäfige auch auf Rachenlehren, indem die Kugelkäfige an den planparallelen Backenflächen solcher Lehren befestigt sind. Die Lehren nach dem Hauptpatent sind sowohl zum Messen von Ring- wie auch Bolzengewinden geeignet; die nachstehend beschriebene Einrichtung gestattet dagegen nur Bolzengewinde zu messen.Device for measuring the pitch diameter of thread object of the main patent is a device for measuring the pitch diameter of threads by means of a ball cage to be rubbed over the thread, in which the measuring balls are loose are set in connection with cylindrically stepped or conical rings or Bolt. The additional invention extends the application possibilities of such ball cages also on snap gauges by placing the ball cages on the plane-parallel jaw surfaces such teachings are attached. The gauges according to the main patent are both for measuring suitable for ring and bolt threads; the facility described below allows only bolt threads to be measured.
Die Abb. i zeigt eine Rachenlehre zum Messen eines etwa 2 Zoll starken Gewindebolzens. Die Lehre ist in der üblichen handlichen Form der gebräuchlichen Rachenlehre gehalten; die Kugeln sitzen lose im Käfig, so daß sie sich ohne Klemmung sowohl an die ebenen Flächen der Lehre wie an die Gewindeflanken anlegen können.Fig. I shows a snap gauge for measuring an approximately 2 inch thick Threaded bolt. The teaching is in the usual handy form of the usual one Throat gauge held; the balls sit loosely in the cage, so that they are without clamping can apply both to the flat surfaces of the gauge and to the thread flanks.
Die Anzahl der Kugeln in zwei zusammengehörigen Kugelkäfigen muß mindestens diei Stück betragen. Ist sie größer, dann werden entsprechend mehr Gewindegänge erfaßt. Jede Lehre muß zwei Kugelkäfige erhalten; die Kugelzabl ist auf der einen Seite meistens gerade und auf der anderen ungerade. Zwei zusammengehörige Kugelreihen sind um die halbe Gewindesteigung zueinander versetzt (Abb. a). Die rückwärtige Anlage der Kugeln im Käfig ist geradlinig, ebenfalls liegen die Kugeln beider Käfige in der gleichen Ebene.The number of balls in two ball cages that belong together must be at least which amount to If it is larger, there will be a correspondingly larger number of threads recorded. Each teaching must have two ball cages; the Kugelzabl is on one Mostly even on one side and odd on the other. Two rows of spheres that belong together are offset from one another by half the thread pitch (Fig. a). The rear The positioning of the balls in the cage is straight, the balls of both cages are also located in the same plane.
Für Toleranzmessungen sind an jeder Backe zwei planparallele Flächen mit je einer Kugelreihe vorgesehen, die in der üblichen Stufenform eingearbeitet sind (Abb. 5 und G). Ferner kann die Toleranz durch die Einfügung einer größeren Kugelsorte in die zweite Reihe bestimmt werden, wobei dann keine Abstufung der planparallelen Flächen erforderlich ist, wie dieses in den Abb. 3 und q. dargestellt ist.There are two plane-parallel surfaces on each jaw for tolerance measurements each provided with a row of balls, which are incorporated in the usual step shape are (Fig. 5 and G). Furthermore, the tolerance can be increased by inserting a larger Ball type in the second row can be determined, with then no gradation of the plane-parallel Areas is required, as shown in Fig. 3 and q. is shown.
Die Befestigung der Käfige an den Backen der Rachenlehre kann durch Schwalbenschwänze oder durch Stifte und Schrauben oder auch durch beide zusammen erfolgen (Abb. 3 und 4).The attachment of the cages to the jaws of the snap gauge can be done by Dovetail or by pins and screws or by both together take place (Fig. 3 and 4).
