Optical scanning sensor system for contactless optical scanning of object surface, has optical unit fastened to head by fastening device having bearings with bearing parts that are formed such that they cause lateral movement of parts

摘要

The system has an optical unit (3) fastened to a sensor head (2) by a fastening device (4) having bearings (20, 21, 22), where each bearing has three pairs of bearing parts (17a, 17b, 18a, 18b, 19a, 19b). The bearing parts pairs are formed such that they cause lateral movement of the parts (17a, 18a, 19a) relative to the parts (17b, 18b, 19b) in a lateral direction based on a bearing plane. The parts (17a, 17b) do not permit lateral movement, the parts (18a, 18b) and the parts (19a, 19b) respectively permit linear lateral movement and two dimensional lateral movement in spatial directions.
