Description

Translated fromGerman

Die Erfindung bezieht sich auf ein Höhenmeß- und Anreiß­gerät zum insbesondere dreidimensionalen Messen und/oder Anreißen von Werkstücken, bestehend aus einem an oder auf einer Richtplatte verschiebbaren Gerätefuß in der X-Achse, einer zur Richtplatte senkrecht stehenden Gerätesäule, an der vertikal in Z-Achse ein Kreuz­schieber geführt ist, wobei über eine geeignete Aus­wertelektronik und entsprechende Werkzeuge ein Anreißen, Messen oder Antasten durchführbar ist.The invention relates to a height measurement and markingdevice for in particular three-dimensional measuring and / orMarking of workpieces consisting of an oron a straightening plate movable device foot in theX-axis, one perpendicular to the straightening plateDevice column, on the vertical in the Z axis a crossslide is guided, with a suitable offvalue electronics and corresponding tools a scribing,Measuring or probing is feasible.

Es sind Höhenmeß- und Anreißgeräte bekannt (z. B. DE-OS 39 42 910), die mit einem auf einer Richtplatte horizon­tal verschiebbaren Fuß und zur Richtplatte rechtwinkelig stehender Säule versehen sind, wobei ein Kreuzschieber vertikal verschiebbar ist und ein Querarm am Ende einen Aufnahmekopf für ein Meß- und Anreißwerkzeug trägt. Die Meß- und Anreißwerkzeuge sind dabei in ihrem Halter drehbar aufgenommen, so daß durch Drehung des Werkzeuges auch Werkstücke mit beliebigen Neigungswinkeln ange­tastet werden können, ohne daß ein Umsetzen und ein neues Justieren des Werkzeuges durchzuführen ist. Bei dieser Ausführung ist von Nachteil, daß mit derartigen Meßsystemen schwer zugängliche Meßpunkte nur unzu­reichend bearbeitet werden können.Height measuring and marking devices are known (e.g. DE-OS39 42 910) with a horizon on a leveling plateadjustable foot and rectangular to the leveling platestanding column are provided, with a cross slideis vertically displaceable and a cross arm at the endCarrying head for a measuring and marking tool. TheMeasuring and marking tools are in their holderrotatably so that by rotating the toolalso workpieces with any angle of inclinationcan be felt without having to move and areadjust the tool. Atthis embodiment has the disadvantage that with suchMeasuring systems difficult to access measuring pointscan be processed sufficiently.
