Description

Die Erfindung bezieht sich auf ein tragbares und/oder transportierbares und/oder stationäres Höhenmess- und Anreißgerät zum insbesondere dreidimensionalen Messen der Position eines Objektes in einem ausgewählten Volumen und/oder Anreißen von Werkstücken, bestehend aus mindestens einem beweglichen, ein Mess- oder Anreißwerkzeug tragenden Arm, dabei wird die Position des Mess- und/oder des Anreißwerkzeuges über Messmittel direkt oder indirekt an einen, ein entsprechendes Rechnerprogramm aufweisenden Rechner zur Bestimmung und/oder Erfassung und/oder Speicherung der Messwerte geleitet.The invention relates to a portable and / or transportable and / or stationary height measuring and marking device for particular three-dimensional measurement of the position of an object in a selected volume and / or scribing of workpieces, comprising at least one movable, a measuring or Anreißwerkzeug bearing Arm, while the position of the measuring and / or the Anreißwerkzeuges is passed via measuring means directly or indirectly to a computer program having a computer for determining and / or acquisition and / or storage of the measured values.

Es sind bereits Höhenmess- und Anreißgeräte bekannt (z. B. DE 44 03 901 A1 ), bei dem das transportable Messgerät mit einem Basisteil und einer entsprechenden Anzahl von Gelenkarmen versehen ist. Die Gelenkarme sind mit dem Basisteil oder jeweils zwei Gelenkteile zueinander mit jeweils einem Drehgelenk versehen, wobei diese Drehgelenke jeweils einen Messwertgeber aufweisen. Die Messwertgeber erkennen die entsprechende Winkelstellung des Drehgelenkes und geben diese Daten zur Erfassung, Bestimmung oder Speicherung der Messwerte an einen Rechner weiter. Zur Erfassung eines Werkstückes bedarf es einer Vielzahl von Messungen bzw. von Messpunkten, um das Werkstück entsprechend abbilden zu können.Height measuring and marking devices are already known (eg DE 44 03 901 A1 ), in which the portable measuring device is provided with a base part and a corresponding number of articulated arms. The articulated arms are provided with the base part or two joint parts to each other, each with a rotary joint, said hinges each having a transducer. The transducers detect the corresponding angular position of the swivel joint and transmit this data to a computer for the purpose of acquiring, determining or storing the measured values. To capture a workpiece, it requires a large number of measurements or measuring points in order to be able to image the workpiece accordingly.

Aufgabe der Erfindung ist es, ein Höhenmess- und Anreißgerät zu schaffen, bei dem unter Beibehaltung der bisher bekannten Bauform eine erhöhte Genauigkeit der Messwerte erzielt werden kann.The object of the invention is to provide a height measuring and marking device, in which an increased accuracy of the measured values can be achieved while maintaining the previously known design.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass das Höhenmess- und Anreißgerät aus mindestens einem Arm und mindestens einem Drehgelenk besteht.To achieve this object, the invention provides that the height measuring and marking device consists of at least one arm and at least one rotary joint.

Eine weitere wesentliche Ausgestaltung sieht vor, dass als Arm ein Kohlefaserrohr zum Einsatz kommt.Another essential embodiment provides that a carbon fiber tube is used as the arm.

Nach einer weiteren Ausführungsform ist vorgesehen, dass das Kohlefaserrohr aus Nano-verstärktem CFK besteht.According to a further embodiment, it is provided that the carbon fiber tube consists of nano-reinforced CFRP.

Hierbei ist mit Vorteil vorgesehen, dass als Nano-Verstärkung Carbon Nanotubes zum Einsatz kommen.In this case, it is advantageously provided that carbon nanotubes are used as the nano-reinforcement.

Dabei bietet die Lösung im Verbund mit Nano-Verstärkungen zum Einen in vorteilhafter Weise die Möglichkeit die elektrische Leitfähigkeit, was den Leitungsaufwand und damit das Gewicht reduzieren würde, und zum Anderen den Verbund der Fasern und damit die Festigkeit des Kohlefaserrohres zu verbessern. Dadurch wird auf Grund des geringeren Gewichtes und der erhöhten Festigkeit die Durchbiegung der als Arm ausgebildeten Verbindungsrohre verbessert was zu erhöhten Genauigkeiten der Messergebnisse führt.The solution in combination with nano-reinforcements on the one hand advantageously offers the possibility of electrical conductivity, which would reduce the cable outlay and thus the weight, and on the other hand improve the bonding of the fibers and thus the strength of the carbon fiber tube. As a result, due to the lower weight and the increased strength, the deflection of the connecting tubes designed as an arm is improved, which leads to increased accuracy of the measurement results.

Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt.Preferred embodiments of the invention are shown schematically in the drawings.

Es zeigt:It shows:

1 ein Höhenmess- und Anreißgerät in Ansicht zwei Armen. 1 a height gauge and scriber device in view two arms.

Das in 1 dargestellte Höhenmess- und Anreißgerät ist zum dreidimensionalen Messen von Werkstücken ausgebildet. Es besteht im Wesentlichen aus dem Basisteil, welches auf dem Fuß 4 fixiert ist, mehreren beweglichen Armen 5, wobei einer der Arme 5 ein Mess- oder Anreißwerkzeug 3 trägt. Die Drehgelenke 2 sind mit Messmitteln versehen und geben ihre Position an einen Rechner 1 weiter. Der Rechner 1 dient zur Bestimmung und/oder der Erfassung und/oder der Speicherung der Messwerte, welche vom Messwerkzeug 3, bestehend aus einem Mess- oder Anreißwerkzeug 3 erzeugt werden. Die vollzogene Messung wird mittels Rechnerprogramm errechnet und gegebenenfalls dargestellt.This in 1 illustrated height measuring and marking device is designed for the three-dimensional measurement of workpieces. It basically consists of the base part, which is on the foot 4 is fixed, several movable arms 5 where one of the arms 5 a measuring or marking tool 3 wearing. The swivel joints 2 are provided with measuring equipment and give their position to a computer 1 further. The computer 1 serves for the determination and / or the acquisition and / or the storage of the measured values, which are provided by the measuring tool 3 consisting of a measuring or marking tool 3 be generated. The completed measurement is calculated by computer program and displayed if necessary.

Die Verbindungsrohre des jeweiligen Armes 5 bestehen aus Carbon Nanotubes die zum Einen den Vorteil bieten, die Möglichkeit die elektrische Leitfähigkeit, was den Leitungsaufwand und damit das Gewicht des Höhenmess- und Anreißgerätes reduzieren würde, und zum Anderen den Verbund der Fasern und damit die Festigkeit des Kohlefaserrohres zu verbessern. Durch das geringere Gewicht und der erhöhten Festigkeit wird die Durchbiegung der als Arm 5 ausgebildeten Verbindungsrohre verbessert sodass erhöhte Mess-Genauigkeiten erzielt werden.The connecting pipes of the respective arm 5 consist of carbon nanotubes on the one hand offer the advantage, the possibility of electrical conductivity, which would reduce the overhead and thus the weight of the height measuring and marking device, and on the other to improve the bond of the fibers and thus the strength of the carbon fiber tube. Due to the lower weight and the increased strength, the deflection of the arm 5 trained connecting pipes improved so that increased measurement accuracy can be achieved.

Die marktüblich eingesetzten Kohlefaserrohre bestehen im Wesentlichen aus Kohlenstofffasern und einer Epoxidmatrix. Somit wird das Verhalten solcher Rohre, neben der Art der Wicklung oder der Kohlefasermatten und der Kohlefasern an sich von der verwendeten Matrix geprägt.The commercially available carbon fiber tubes consist mainly of carbon fibers and an epoxy matrix. Thus, the behavior of such tubes, in addition to the type of winding or the carbon fiber mats and the carbon fibers per se is characterized by the matrix used.

Die Eigenschaften der Matrix beeinflussen vor allem die mechanischen Größen Scherfestigkeit und Widerstand gegen Rissfortschritt und die elektrische Leitfähigkeit, liefern aber auch einen Beitrag zum Widerstand gegen Durchbiegung. Durch das Einbringen von Carbon Nanotubes werden die Eigenschaften der Matrix beeinflusst und verbessert, sodass die Festigkeit und Steifigkeit des Kohlefaserrohres ebenso gesteigert werden kann wie dessen elektrische Leitfähigkeit.Above all, the properties of the matrix influence the mechanical properties of shear strength and resistance to crack propagation and electrical conductivity, but also contribute to the resistance to deflection. By incorporating carbon nanotubes, the properties of the matrix are influenced and improved, so that the strength and rigidity of the matrix Carbon fiber tube can be increased as well as its electrical conductivity.

Das Einbringen der Nanotubes verbessert somit auch die Eigenschaften der Verbindungsarme und somit die Eigenschaften des kompletten Höhenmess- oder Anreißgerätes.The introduction of the nanotube thus also improves the properties of the connecting arms and thus the properties of the complete height measuring or scriber device.
