  1. 1. A198_eLaser sensors and 2D/3D Laser ScanneroptoNCDT & scanCONTROL3D profile measurement of parts with rotational symmetryAs two rotary pistons must always mesh with each otherin rotary piston pumps and these terminate with the pumpwall, the exact dimensional accuracy of the rotary pistonsis critical. The required service life can only be maintainedif the fitting of the piston surface to the pump housing isoptimised. Therefore, the complete surface of the pistonis measured and compared with the target shape to stricttolerances.Qsigma GmbH based in Kassel, Germany has developeda universal 3D measuring machine for these applications.The rotary piston is positioned on the rotating axis. AscanCONTROL 2700 profile scanner with 50mm measur-ing range is used to record the surface profile and shape.For larger components, the profile scanner can be tra-versed vertically on a linear axis.An integrated optoNCDT 2200 laser sensor with 200mmmeasuring range is also used to determine the exact po-sition. This sensor acquires 10,000 distance values everysecond with a resolution of 3µm.The object rotates during the measurement. Only five sec-onds are required for the automatic inspection process.After successfully scanning the surface geometry, themeasurement data is compared with the target object. Inaddition to rotary pistons, the system can also be used onmany other objects with rotational symmetry.MICRO-EPSILON A member of micro-epsilon groupKönigbacherstr. 15 Tel. +49 (0) 85 42/1 68-0 info@micro-epsilon.com Certified DIN EN ISO 9001 : 200094496 Ortenburg/Germany Fax +49(0) 85 42/1 69 90 www.micro-epsilon.com Modifications reserved / 9781198-A011030FHF
