Description

Die Erfindung betrifft ein Längenmeßgerät mit einem Taststift, dessen Bewegung über ein Getriebe auf den Meßzeiger übertragen wird, und mit einem mit zwei den schwenkbaren Kontakthebel umschließenden Gegenkontakten ausgerüsteten Kontaktgeber zur elektrischen Anzeige der Toleranzstellungen des Taststiftes. Bei den bisher bekannten Geräten ist für jeden Gegenkontakt eine Einstellschraube vorgesehen. Das Einstellen des Toleranzbereiches ist daher umständlich. The invention relates to a length measuring device with a stylus whose Movement is transmitted to the measuring pointer via a gear, and with a two contactors equipped with mating contacts surrounding the pivotable contact lever for the electrical display of the tolerance positions of the stylus. With the so far known devices, an adjusting screw is provided for each mating contact. That Setting the tolerance range is therefore cumbersome.

Erfindungsgemäß wird eine wesentliche Vereinfachung dadurch erzielt, daß nur eine einzige Stellschraube vorgesehen ist, die auf beide Gegenkontakte gleichzeitig einwirkt. Dadurch ist es möglich, durch Verstellen einer einzigen Schraube die Toleranz nach beiden Seiten hin gleichmäßig zu verändern. According to the invention, a significant simplification is achieved by that only a single adjusting screw is provided, which acts on both mating contacts at the same time acts. This makes it possible to adjust the tolerance by adjusting a single screw to change evenly on both sides.

Die Zeichnung zeigt in Abb. 1 den Kontaktgeber an einer normalen Meßuhr in Draufsicht und in Abb. 2 diesen in Seitenansicht. The drawing shows in Fig. 1 the contactor on a normal Dial gauge in plan view and in Fig. 2 this in side view.

Im Fühlstift I2 ist der Mitnehmer 10 mit Gewinde befestigt. Er berührt an seinem geläppten Schaft den geläppten Hebelkontakt 9, welcher durch eine Rückzugfeder anliegt. Zwei gegenüberliegende federnde Kontakte 4 und 5 sind entsprechend elektrisch isoliert so angeordnet, daß sie an dem Kegel der Schraube 6 anliegen, und je nach Kegelstellung ist das elektrische Toleranzfeld größer oder kleiner. Die Platte 3 ist als Schieber ausgebildet und leicht beweglich, verschiebbar oder um einen Punkt schwenkbar und durch Feder 14 kraftschlüssig an die Stellschraube 2 gezogen. The driver 10 is fastened with a thread in the feeler pin I2. He touches on its lapped shaft the lapped lever contact 9, which by a return spring is applied. Two opposing resilient contacts 4 and 5 are correspondingly electrical isolated so that they rest against the cone of the screw 6, and depending on Cone position, the electrical tolerance field is larger or smaller. The plate 3 is designed as a slide and is easily movable, shiftable or around a point pivotable and pulled to the adjusting screw 2 in a force-locking manner by the spring 14.

Durch Verstellen der Schraube 2 ändert sich die Lage der Platte gegenüber Führung I3 und damit der Berührungspunkt der Teile g und IO. Der Hebel g mit Gegenkontakten und deren Verstellung verändern durch Verschieben oder Schwenken der Platte jeweils ihre Stellung zum Mitnehmer Io.Adjusting the screw 2 changes the position of the plate opposite Guide I3 and thus the point of contact of parts g and IO. The lever g with mating contacts and change their adjustment by moving or pivoting the plate, respectively their position on the carrier Io.

Damit wird das bereits durch die Schraube 6 eingestellte elektrische Toleranzfeld über den gesamten Fühlstiftweg an jeder beliebigen Stelle in Schaltwirkung gebracht. Die Kontaktgabe sowie die Schaltung der Signallampen II direkt oder über Relais ist bekannt und soll nicht noch einmal beschrieben werden.This becomes the electrical already set by the screw 6 Tolerance field over the entire feeler pin path at any point in the switching effect brought. The contact and the switching of the signal lamps II directly or via Relay is known and will not be described again.
