摘要

Measuring device which acts on a non-linear in order to improve by analyzing the regulation of the orientation device acting spherical. The present invention relates to a measuring device for the measured relative (9) frame plate that is spatially fixed, a small movement (17) a tool center point pivotally tool (16). It can be carried out using the measurement results, to improve the calibration (16) for pivotally tools, to improve the accuracy of motion thereby. The present invention is made up of (1) measuring finger movable in three axes of the spherical coordinate system, the measuring fingers is combined with (4) transmission members of the boomerang-shaped via linear guide portion (3) is, the transmission member itself is coupled to the frame plate (9) and (12) universal joint. Transmission member boomerang-shaped (4), the linear measurement three members acting linearly (6), (7), (8) is mounted, without clearance and frictionally expression linear measuring device of these is combined with (1) measuring finger frame plate (9), the measurement result is described uniquely measured relative position of the finger (1) relative to the frame plates (9) by the forward transform. Has a (18) measuring sphere that fixedly located axis of symmetry are pivotally tool (16), this measurement sphere, forming part of a spherical crown on the top of the (1) measured finger (24 to form a chain of non-movement in-line to engage), defined statically.
