Measurement and/or positioning device, has three linear positioning elements with one end freely pivotable on second machine part, other ends at node, fourth element from node to first part

摘要

The device has first, second and third linear positioning elements with one end freely pivotable at a distance from each other on the second machine part and the other ends coming together at a node whose position is defined by their linear lengths, and a fourth element with a main direction between the node and the first machine part. The lengths of the first and/or fourth and the second and third elements can be varied reproducibly. The device has a first, second and third linear positioning elements (6-8), each with a main direction and each with one end freely pivotable at a distance from each other on the second machine part (3) and the other ends coming together at a node (9) whose position is defined by the linear lengths of the positioning elements, and a fourth linear positioning element (13) with a main direction between the node and the first machine part (2). The lengths of the first and/or fourth and the second and third elements can be varied reproducibly.
