Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0029] figure 1 The adjusting device 1 according to the invention is shown in a perspective exploded view. The base body 2 made of titanium Ti6Al4V (grade 5) comprises a total of four base body recesses 100 for respectively accommodating a drive element 3 in the form of a piezoelectric linear actuator. The piezoelectric linear actuator is subjected to compressive stress in the direction of its longitudinal extension by a pretensioning device 120 comprising a substantially T-shaped pretensioning element 121 , two compression springs 122 and a bearing part 123 . In the assembled state of the adjustment device, each compression spring 122 is partially embedded in a corresponding recess of the pretensioning element 121 and one of its two distal ends abuts or bears against the pretensioning element 121 . The other distal end of each compression spring abuts or is supported on the a...

Abstract

The invention relates to an adjustment device (1) comprising a base body (2), at least two drive elements (3) for driving movement, and a platform (4) movable relative to said base body, wherein each of said drive The element abuts against a lever transmission (5) associated with said drive element, and the drive movement of the drive element transmitted by said lever transmission passes through an engagement element (6) connected to said lever transmission and said platform transferred to the platform, and on the platform there is also arranged an elastic element (7) for guiding the adjustment movement and firmly connected to the base body, wherein the elastic element counteracts the inclination caused by the adjustment movement A parasitic translational movement in the plane of the platform and / or a parasitic rotational movement of the platform about a rotation axis arranged perpendicularly to the platform plane. The invention also relates to the use of said adjustment device in a tilting mirror unit.

Description

technical field [0001] The invention relates to an adjustment device and the use of such an adjustment device in a tilting mirror unit. Background technique [0002] An adjustment device for an optical element is known from DE 103 44 178 B4, in which the optical element is mounted on a base body via a manipulator unit. The manipulator unit there comprises a linear adjustment element and a movable manipulator member, wherein the linear adjustment element and the movable manipulator member are connected to each other by a flexible hinge arrangement. The movable manipulator member itself is connected by an additional flexible hinge to the manipulator head, on which the optical elements are arranged by means of a frame ring. [0003] The flexible joint arrangement is designed in such a way that it acts as a lever reduction, whereby an already small adjustment movement of the linear adjustment element can be converted into an even lower and highly precise adjustment movement of ...
