Abstract
Description
Die Erfindung bezieht einem Mikrometer mit verschiebbarem Amboß für die Messung und Kontrolle der Feinmaße von Teilen und verwen det im Werkstatt der Fabriken und im Laboratorium für Kontrolle und Messung.The invention relates to a micrometer with a displaceable anvil for measuring and checking the fine dimensions of parts and use in the factory workshop and in the control laboratory and measurement.
Bekannt Standardmikrometer für dieses Ziel, aber er hat folgende Fehler:Known standard micrometers for this goal, but it has the following Error:
- 1. Bei der Arbeit von Messung und Kontrolle die Arbeitsfläche von Gewinde des Meßspindels 4 und Gewindehülse und die Stirnmeß fläche von Amboß 2 und Meßspindels 4 nützen sich ab; daß gibt die Verschiebung des Nullrisses von Meßtrommel von Nullage, welche gibt die Fehler der Messung.1. In the work of measurement and control, the working surface of the thread of the measuring spindle 4 and the threaded sleeve and the front measuring surface of the anvil 2 and the measuring spindle 4 wear out; that gives the displacement of the zero crack of the measuring drum from zero position, which gives the errors of the measurement.
- 2. Bei Montage und Fertigbearbeitung der Meßflächen von Meß spindel und Amboß solche Verschiebung macht schwierig die Justie rung.2. When assembling and finishing the measuring surfaces from Meß spindle and anvil such displacement makes the adjustment difficult tion.
In der Erfindung liegt die Aufgabe zugrunde, daß bei Aus schließung der Fehler, ein Mikrometer erschaffen, in welchen ist möglich die Verschiebung von Nullage zu korrektieren, was vergrö ßert seine Frist zu arbeiten in viel Mal.In the invention, the object is that at off closing the mistakes, creating a micrometer in which is possible to correct the shift from zero position, which increases eats his time to work in a lot of times.
Die Lösung dieser Aufgabe ergibt sich aus den kennzeich nenden Merkmalen des Anspruchs 1.The solution to this problem results from the characteristics nenden features of claim 1.
Die Erfindung ist in den Zeichnungen dargestellt. Es zeigtThe invention is shown in the drawings. It shows

Die Einrichtung der ersten Variante wird gemacht folgender maßen:The setup of the first variant is done the following measure:
- 1. Drehend die Kurvenscheibe 7 man befestigt schwach den Amboß 2, weil sie hat eine Exzentrizität "ε".1. Rotating the cam 7 weakly fastens the anvil 2 because it has an eccentricity " ε ".
- 2. Drehend den Schalltrieb 6 man stellt den Mikrometer in Nullage.2. Rotating the sound drive 6 , the micrometer is set to zero position.
- 3. Mit ergänzenden Drehung der Kurvenscheibe 7 man befestigt stark den Amboß 2.3. With additional rotation of the cam disc 7 , the anvil 2 is strongly fastened.
Die Einrichtung der zweiten Variante man macht folgender maßen, aber man dreht die Mutter 9.The second variant is set up as follows, but the nut 9 is turned .
In allen Fällen muß sein der Spalt Δ zwischen der Stirn des Ambosses 2 und Seitenfläche des Bügels 1.In all cases there must be the gap Δ between the forehead of the anvil 2 and the side surface of the bracket 1 .
Nach dauerende Arbeit entsteht die Verschiebung des Nullris ses von Nullage. Dann man macht Überrichtung nach die drei Punkten.After continuous work there is a shift in the zero risk ses of nullage. Then you make the three points.
