Equipment for micrometric monitoring of surfaces, comprises optical or similar capturing unit which is given simultaneous linear and circular motions from a common drive through a cam and a crown

摘要

The surface (2) is monitored by an optical or similar sensor unit (3) which is mounted on a trolley (8) with guide rails (9). The guide rails are fixed to the bottom of a drum (11) which is rotated about an axis (10) by a motor (13), first motor pinion (14) and crown (15). The sensor unit is simultaneously propelled longitudinally by a cam (17) which is driven by a second motor pinion (22) and drum (21)
