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.
Aufgabe der Erfindung ist es, ein Höhenmeß- und Anreißgerät zu schaffen, bei dem die Werkzeuge auch schwer zugängliche Meß- und Anreißpunkte erreichen können, so daß auch ein Einsatz in Hohlräumen von außen möglich wird.The object of the invention is a height measuring and markingcreate device where the tools are also difficultcan reach accessible measuring and marking points, sothat use in cavities from the outside is also possiblebecomes.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß zwischen dem Kreuzschieber und dem Werkzeug mindestens zwei Gelenkarme angeordnet sind, wobei jedem Gelenkarm mindestens ein, mit der Auswertelektronik verbundener, Meßgeber zugeordnet ist.To solve this problem, the invention providessee that between the cross slide and the toolat least two articulated arms are arranged, eachArticulated arm at least one, with the evaluation electronicsconnected, sensor is assigned.
Vorteilhaft ist bei dieser Ausbildung, daß über die Gelenkarme und den Meßgeber ein Antasten von schwer zugänglichen Meßpunkten erreicht werden kann. Es lassen sich durch eine derartige Konstruktion z. B. die Hohlräume von Kotflügeln eines Kraftfahrzeuges von außen, als auch der Fahrgastinnenraum eines Kraftfahrzeuges durch die Türen von außen erreichen und entsprechend vermessen bzw. anreißen.It is advantageous in this training that aboutArticulated arms and the transducer a probing difficultaccessible measuring points can be reached. Leave itsuch a construction z. B. the hollowclearing fenders of a motor vehicle from the outside,as well as the passenger compartment of a motor vehiclereach through the doors from the outside and accordinglymeasure or mark.
Nach einem wesentlichen Merkmal ist vorgesehen, daß mindestens drei Gelenkarme vorgesehen sind. Vorteilhaft ist hierbei, daß der bis dahin übliche Querarm für die Y-Achse entfallen kann, da die Gelenkarme direkt mit dem Kreuzschieber in Verbindung stehen.According to an essential feature, it is provided thatat least three articulated arms are provided. Advantageousis that the usual cross arm for theY axis can be omitted because the articulated arms directly with theCross slide are connected.
Eine besonders günstige Ausführungsform sieht vor, daß dem dem Kreuzschieber zugewandten Gelenkarm ein in Y-Achse verschiebbarer Querarm vorgeschaltet ist. Hierbei wird mit Vorteil dem bereits bekannten Querarm entsprechende Gelenkarme für die vierte und fünfte Achse zugeordnet.A particularly favorable embodiment provides thatthe articulated arm facing the cross slide inY-axis movable cross arm is connected upstream. Hereat the advantage is the already known cross armcorresponding articulated arms for the fourth and fifth axesassigned.
In Ausgestaltung der Erfindung sind als Meßgeber Drehgeber vorgesehen. Bei der Verwendung von Drehgebern werden in weiterer Ausgestaltung jedem Gelenkarm als Meßgeber mindestens zwei Drehgeber zugeordnet, so daß die jeweilige Position des Gelenkarmes in drei Freiheitsgraden problemlos ausgewertet werden kann.In an embodiment of the invention are rotary as a transmitterenvisaged. When using encoders are in a further embodiment each articulated arm asSensor assigned at least two encoders, so thatthe respective position of the articulated arm in three freedegrees can be easily evaluated.
Eine besonders günstige Ausführungsform sieht vor, daß die Richtplatte mit zwei Gerätesäulen versehen ist.A particularly favorable embodiment provides thatthe straightening plate is provided with two device columns.
