Coincidence manipulator esp. for adjusting already mounted optical components - has displacement pick=ups reacting vertically on underside of object reception table and translation elements working under control of microprocessor

摘要

The manipulator consists of a reception table (5) for the object which is arranged play free secured to the frame across a spring element (4) designed as an abutment, as well as consisting of at least two translation elements, arranged uniformly distributed in the abutment on a track concentric to a manipulator axis, provided with displacement pickups reacting vertically on the underside of the object reception table. The translation elements work in conjunction with a microprocessor. The spring element (4) is made of body characteristic material in the form of a flexure hinged column or in the form of a characteristically reduced cross section cylinder spring web combination (18) by openings (17). The spring element (4) is surrounded by a coaxial spring with four translation elements (9-12) arranged displaced at 90 deg., reacting horizontally on the spring element (4). The coaxial spring consists of an outer frame fixed ring (2) and an inner spring ring (3) effecting the fixing of the translation elements (9,10) and the vertically working translation elements (11,12) are arranged functionally separated in different planes. ADVANTAGE - Hinge element works as quasi stationary bearing, facilitating working together of all translation elements in correlation with location of object reception table to give play and stick slip free reproducible adjustment of object in static and dynamic condition.
