Abstract:
An apparatus for fine positioning of a component comprises:a) a one-piece double parallel spring element (1) having an axis of symmetry (2), comprising i) an external stationary frame (3) on whose inner side two holding elements (4, 5) are shaped at positions lying opposite one another about the axis of symmetry (2); ii) a movable center bar (6) between the holding elements (4, 5); iii) two movable side bars (7, 8) arranged on either side of the center bar (6); and iv) pairs of parallel connecting elements (9), arranged on either side of each holding element (4, 5) and equipped at the ends with bending points (10), the first connecting element (9) being in each case joined to one side bar (7, 8) and one holding element (4, 5), and the second connecting element (9) being in each case joined to the side bar (7, 8) and the center bar (6); b) an elastic element (11) between a holding element (4, 5) and one end of the center bar (6); and c) a fine adjustment element (12) that is arranged between one holding element (4, 5) and one end of the center bar (6).
