Abstract
The scanning head according to the invention has the horizontal main axis (1) and is provided for numerically controlled gear measuring devices. Its feeler (2) is guided by a linear slide (4) and the latter is guided by a leaf spring parallelogram (11, 12, 13, 14) in the two coordinate directions (6) and (16). Mechanical devices (8) and (18) hold the feeler in a definite central position from which it can be deflected with the same measuring force in both the positive and negative coordinate directions. A centrally located two-dimensional ruled grating scale (10) detects all deflections of the feeler in the plane spanned by the two coordinates. To adjust the third coordinate direction, a pivot mechanism (3) is used, with a roller bearing (2) being provided for weight balance for the leaf spring parallelogram, the outer ring of the bearing being suspended by at least two springs (21, 22) on a fixed part (23) above the scanning head.
