Tooth aligning device for the aligning of workpiece with pre-cut teeth on gear finishing machines
First Claim
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.

Abstract
The invention concerns a device for the non-contact measurement of the position of the teeth (13) of a workpiece (14) with precut teeth on a gear finishing machine. The measuring probe, retractable from the measuring position into a position of rest protected against soiling, is arranged in a holder (5) for radial and axial adjustment relative to the workpiece, the said holder (5) being a kinematic member of a parallelogram linkage (A) and by means of a hydraulic, pneumatic or electromechanical swivel drive (11) is swivellable from stop to stop between measuring position and position of rest in a plane containing the workpiece axis, such that in the advancement action from the lower end position to the top end position motions of the measuring probe (1) tangential to the workpiece circumference are completely avoided. The parallelogram kinematics moreover afford adequate protection against swarf and grinding dust, and lends the device a high stiffness and reliability.
