Abstract:
1. Device for the non-contact measurement of the position of the teeth of a workpiece with pre-cut teeth, which is set up for fine machining on the work spindle of a gear finishing machine, said work spindle being rotatable about a rotary axis and said gear finishing machine having a machine bed, said device comprising: a retractable measuring probe, which is moveable in a fixed swivel plane between a first fixed measuring position and a second fixed retracted position, said swivel plane being parallel to or coinciding with said rotary axis; a double parallelogram linkage that comprises two parallelogram linkages between which said swivel plane is disposed, said two parallelogram linkages having identical swivel axes perpendicular to said swivel plane and being connected to move synchronously with one another, and said double parallelogram linkage having first and second ends; a holder carrying said probe, said holder being arranged between and connecting said two parallelogram linkages at the first end of said double parallelogram linkage, such that said probe is protected by said two parallelogram linkages when being in said second fixed retracted position; and a base member opposite said holder, said base member being rigidly connected to the machine bed or a work spindle housing, said base member being arranged between and connecting said parallelogram linkages at the second end of said double parallelogram linkage.
