Description
Die Erfindung betrifft Verfahren nach Anspruch 1 und eine Hilfseinrichtung nach Anspruch 4 zum Positionieren einer Stütze für ein Messobjekt zum Vermessen mit einem Koordinatenmessgerät.The The invention relates to method according to claim 1 and an auxiliary device according to claim 4 for positioning a support for a measurement object for surveying with a coordinate measuring machine.
Bei einem Koordinatenmessgerät werden mit einem Taster verschiedene Messpunkte eines Messobjektes angetastet und deren Koordinaten gespeichert. Aus einer anschließenden Verarbeitung der Punktkoordinaten ergeben sich Messwerte für Abmessungen, wie Länge, Breite oder Dicke, eines Werkstückes oder einer Baugruppe oder für den Abstand zwischen Flächen und/oder Kanten eines Werkstückes oder zwischen zwei Werkstücken. Ein Taster wirkt berührend oder berührungslos und ist an einem Tastkopf befestigt. Für verschiedene Messaufgaben sind unterschiedliche Tastköpfe mit speziellen Tastern vorgesehen. Deshalb ist ein Tastkopf am Messarm eines Koordinatenmessgerätes austauschbar vorgesehen. Um unnötigen Justieraufwand zu vermeiden bestehen zwischen Tastkopf und Messarm mechanische Schnittstellen mit Schnellkupplung des Tastkopfes. Damit mit dem Messarm jeder gewünschte Messpunkt angefahren werden kann, ist der Messarm mit dem Tastkopf in drei Koordinatenrichtungen positionierbar.at a coordinate measuring machine With a push-button, different measuring points of a measuring object are detected touched and stored their coordinates. From a subsequent processing of the Point coordinates yield measured values for dimensions, such as length, width or thickness, of a workpiece or an assembly or for the distance between surfaces and / or edges of a workpiece or between two workpieces. A button is touching or contactless and is attached to a probe. For different measuring tasks are different probes provided with special buttons. Therefore, a probe is on the measuring arm a coordinate measuring machine replaceable provided. To unnecessary Adjustment effort to avoid exist between probe and arm mechanical interfaces with quick coupling of the probe. In order to Any desired one with the measuring arm Measuring point can be approached, is the measuring arm with the probe positionable in three coordinate directions.
Beim Messen von Koordinaten an Messobjekten mit einer komplizierten Geometrie, wie zum Beispiel an einer Karosserie, werden bestimmte Punkte des Messobjektes als Referenzpunkte festgelegt. Vor Beginn einer Koordinatenmessung wird das Messobjekt im Koordinatenmessgerät an den Referenzpunkten auf an Stützen befindlichen Auflageelementen abgelegt. Die Positioniergenauigkeit der Auflageelemente bestimmt maßgeblich die Messgenauigkeit. Zum Positionieren der Auflageelemente werden die Stützen auf einer ebenen Messplattform verschoben und die Auflageelemente in der Höhe eingestellt. Die waagerechte Messplattform liegt in einer Ebene parallel zur einer Ebene, die durch x-y-Koordinatenachsen aufgespannt ist. Die Höhenverstellung der Auflageelemente erfolgt in Richtung der z-Koordinatenachse. Hat ein Auflageelement nach mehreren Mess- und Positionierschritten die Solllage erreicht, werden die betreffende Stütze auf der Messplattform und die Höhenverstellung des Auflagepunktes in der Höhe fixiert.At the Measuring coordinates on DUTs with complicated geometry As for example on a bodywork, certain points of the Measurement object defined as reference points. Before starting a coordinate measurement the measuring object is in the coordinate measuring machine at the reference points on supports stored support elements stored. The positioning accuracy of Support elements determined significantly the measuring accuracy. To position the support elements the pillars moved on a flat measuring platform and the support elements in height set. The horizontal measuring platform lies in one plane parallel to a plane spanned by x-y coordinate axes is. The height adjustment the support elements takes place in the direction of the z-coordinate axis. Has a support element after several measuring and positioning steps reaches the target position, the relevant support on the measuring platform and the height adjustment of the Point of support in height fixed.
Zur Positionierung eines höhenverstellbaren Auflageelementes an einer auf einer Messplattform frei beweglichen Stützsäule ist es bekannt, eine greiferartige Lehre mit einem wiederholsicheren Schnellanschluss an einem Flansch eines Arms eines Koordinatenmesssystems zu verwenden. Der Arm des Koordinatenmessgerätes wird so verfahren, dass mit der Lehre das Auflageelement ergriffen werden kann. Weiterhin wird der Arm in eine Sollposition gefahren, wobei die Stützsäule in der x-y-Ebene und das Auflageelement in z-Richtung von der Lehre mitgenommen wird. In Sollposition werden die Stützsäule auf der Messplattform und das Auflageelement in der Höhe fixiert. Die Positionierung des Auflageelementes mittels der Tastkopfantriebsmittel des Koordinatenmesssystems erfordert wegen der Masse der Lehre und den erforderlichen Positionierkräften einen hohen konstruktiven Aufwand. Ohne entsprechende Steifigkeit der Positioniermittel in den drei Koordinatenachsen ergeben sich Positionierfehler.to Positioning of a height-adjustable support element on a freely movable support column on a measuring platform It is known, a claw-like doctrine with a repeatable Quick connection to a flange of an arm of a coordinate measuring system to use. The arm of the coordinate measuring machine is moved so that with the teaching of the support element can be taken. Farther the arm is moved to a desired position, wherein the support column in the x-y plane and that Support element is taken in the z-direction of the teaching. In Target position, the support column on the Fixed measuring platform and the support element in height. The positioning of the support element by means of the probe drive means of the coordinate measuring system requires a high because of the mass of the teaching and the required positioning forces constructive effort. Without appropriate stiffness of the positioning positioning errors occur in the three coordinate axes.

Aufgabe der Erfindung ist es, ein Verfahren und eine Hilfseinrichtung zum Positionieren einer Stütze für ein Messobjekt zum Vermessen mit einem Koordinatenmessgerät zu entwickeln, welche mit geringem Aufwand eine hohe Positioniergenauigkeit ermöglichen.task The invention relates to a method and an auxiliary device for Positioning a support for a To develop a measuring object for measuring with a coordinate measuring machine, which allow high positioning accuracy with little effort.
Die Aufgabe wird mit einem Verfahren gelöst, welches die Merkmale nach Anspruch 1 aufweist. Eine Hilfseinrichtung zur Durchführung des Verfahrens ergibt sich aus den Merkmalen nach Anspruch 4.The Task is solved with a method which the features after Claim 1. An auxiliary device for carrying out the Method results from the features of claim 4.
Gemäß dem Verfahren wird ein Positionierelement am Messarm eines Koordinatenmessgerätes mit den Koordinatenmessgerät eigenen Antrieben in eine bestimmte Position gebracht und dort festgesetzt. Eine Stütze für ein Messobjekt wird anschließend auf einer x-y-Messplattform unter das Positionierelement verschoben. Danach wird ein Auflageelement für das Messobjekt an der Stütze in der Höhe bis zum Positionierelement verstellt. Das Positionierelement besitzt Führungen für das Auflageelement, so dass bei der Höhenverstellung die Position der Stütze auf der Messplattform selbsttätig korrigiert wird, falls das Auflageelement nicht exakt unter dem Positionierelement stand. Ist die Solllage des Auflageelementes erreicht, wird die Stütze auf der Messplattform festgelegt und die Höhenverstellung des Auflageelementes fixiert.According to the method, a positioning element on the measuring arm of a coordinate measuring machine with the coordinate measuring machine's own drives is brought into a specific position and fixed there. A support for a measurement object is then placed on an xy measurement platform below the positio shifted nierelement. Thereafter, a support element for the object to be measured on the support in height is adjusted to the positioning. The positioning element has guides for the support element, so that in the height adjustment, the position of the support on the measuring platform is automatically corrected if the support element was not exactly below the positioning. Once the desired position of the support element has been reached, the support is fixed on the measuring platform and the height adjustment of the support element is fixed.
Besonders vorteilhaft ist ein Positionierelement mit einem Aufnahmekegel für ein kugelförmiges Auflageelement. Das Positionierelement wird so ausgerichtet, dass die Achse des Aufnahmekegels in z-Richtung senkrecht zur Messplattform steht und der Aufnahmekegel dem Auflageelement zugewandt liegt. Im Aufnahmekegel sind elektrische Kontakte eingelassen, die überbrückt werden, wenn das Auflageelement die Solllage einnimmt. Die Kontaktfläche weist die Geometrie der Kegelfläche des Aufnahmekegels auf. Das Erreichen der Solllage kann optisch oder akustisch signalisiert werden. Die Signalisierungselemente inklusive Stromversorgung können direkt im Positionierelement untergebracht sein.Especially advantageous is a positioning with a receiving cone for a spherical support element. The positioning element is aligned so that the axis of the Recording cone is in the z-direction perpendicular to the measuring platform and the Receiving cone facing the support element. In the recording cone are electrical contacts inserted, which are bridged when the support element the target position occupies. The contact surface has the geometry of conical surface of the receiving cone. Reaching the desired position can optically or be signaled acoustically. The signaling elements included Power supply can be direct be housed in the positioning.
