Description

Die Erfindung betrifft eine Vorrichtung zum Lehren der Länge von Zapfen an Werkstücken, mit der es möglich ist, genau und schnell lehren zu können, wodurch weitgehendst Arbeitszeit gespart wird. The invention relates to a device for teaching the length of Tenons on workpieces, with which it is possible to teach accurately and quickly, which largely saves working time.

Ein Ausführungsbeispiel ist in der Zeichnung dargestelit. An embodiment is shown in the drawing.

Die Vorrichtung besteht aus der aus elektrisch leiten dem Werkstoff hergestellten Lehre a. An der Lehre a liegt im Ruhezustand ein elektrisch leitender Meßbolzen b an, auf dem vor der Lehrenziftnullg ein Isolierstück c angeordnet ist. Weiterhin gleitet der Meßbolzen b in einer Isolierumhüllung d, auf der hinter dem Meßbolzen eine elektrisch leitende Metallplatte e in einem bestimmte Abstand von der Lehre a befestigt ist. The device consists of the electrically conductive material produced teaching a. In the idle state, there is an electrically conductive one at the teaching a Measuring bolt b on which an insulating piece c is arranged in front of the Lehrenziftnullg. Furthermore, the measuring pin b slides in an insulating cover d on the behind the Measuring bolt an electrically conductive metal plate e at a certain distance from the doctrine a is attached.

Um den Meßbolzen b jeweils gegen die Lehre a anzudrücken, ist an seiner Rückseite ein Zapfen angebracht, der unter Federdruck der Feder g steht. To press the plunger b against the gauge a, is on a pin attached to its rear side, which is under spring pressure from the spring g.

I)er Zapfen f und somit der damit verbundene Meßbolzen b erhält Strom von der Stromquelle, z. B. dem Transformator k, wobei je nach Lage des Meßbolzens b die beiden Stirnseiten i oder j des Meßbolzens b mit der Metallplatte e oder der Lehre a die Kontaktstellen bilden.I) he pin f and thus the measuring pin b connected to it receives current from the power source, e.g. B. the transformer k, depending on the position of the plunger b the two end faces i or j of the measuring pin b with the metal plate e or the Teaching a form the contact points.

I)ie Lehre a und die Metallplatte e sind über je eine Signallampe k und I mit der zweiten Anschlußklemme der Stromquelle h verbunden. I) he gauge a and the metal plate e are each over a signal lamp k and I connected to the second connection terminal of the current source h.

L)ie Arbeitsweise des Gerätes ist folgende: In ltuhestellung der Vorrichtung brennt die Signallampe k und zeigt somit die Arbeitsbereitschaft der Vorrichtung an. L) he mode of operation of the device is as follows: When the Device burns the signal lamp k and thus shows the readiness for work Device on.

Wird nun der zu lehrende Zapfens des Werkstücks nt in die Lehrenöffnung o der Lehre a eingeführt, so muß bei Maßhaltigkeit des Zapfens tt die Larnpe k erlöschen. Erlischt selbige nicht, so ist der Zapfen n zu kurz, also nicht maßhaltig. Leuchtet tm Gegensatz hierzu die Signallampe I auf, so ist der Zapfen ist des Werkstücks m zu lang. If the pin to be taught is now nt into the jig opening o the gauge a introduced, the Larnpe k must go out if the pin tt is dimensionally accurate. If it does not go out, the pin n is too short, i.e. not dimensionally accurate. Shines In contrast to this, the signal lamp I is on, the pin is the workpiece m too long.

Hieraus folgt, daß die Maßhaltigkeit des zu lehrenden Zapfens n des NVerkstücks m mittels der Vorrichtung dadurch feststellbar ist, daß weder die Signallampe k noch die Signallampe 1 brennt. In diesem Falle sind beide Kontaktstellen i und j geöffnet, da die Länge des Zapfens größer als die Dicke a2 der Lehre a, jedoch kleiner als die durch die Vorrichtung gegebene Strecke, die sich aus a2 und dem möglichen Verschiebeweg des Meßbolzens b ergibt, ist, so daß die Zapfenlänge innerhalb dieser Toleranzen liegt. It follows that the dimensional accuracy of the pin to be taught n des NVerkstücks m can be determined by means of the device that neither the signal lamp k signal lamp 1 is still on. In this case, both contact points are i and j opened because the length of the pin is greater than the thickness a2 of the gauge a, however smaller than the distance given by the device, which is made up of a2 and the possible displacement of the measuring pin b results, so that the pin length within these tolerances lies.
