Abstract:
A device for setting up a work-piece on a machine for fine machining of gears by a gear-shaped or worm-shaped tool, wherein the workpiece is positioned relative to the tool for determining a starting and an end position of a machining operation, the device comprisinga machine base (1, 22), a tool spindle (4) located for rotation about a tool axis (33), the tool spindle being connected to a first motor (43) and to a first angular encoder (45), a work spindle (8, 26) located for rotation about a workpiece axis (31), the work spindle being connected to a second motor (44) and to a second angular encoder (46), a first slide (2, 19) for displacing the tool spindle (4) relative to the work spindle (8, 26) parallel to the tool axis (33), a second slide (7, 23) for displacing the work spindle (8, 26) relative to the tool spindle (4) parallel to the workpiece axis (31), wherein both slides can be actuated by one feed drive element (47, 48) each and a slide stroke is measured by one position sensor (49, 50) each, and wherein all motors, feed drive elements position sensors and angular encoders are connected with an NC control unit (51), the device further comprising a laser line projector (12), a beam plane (30) of which intersects the workpiece axis (31) at right angles, and which is displaceable relative to the work spindle (8) parallel to the workpiece axis (31), a displacement stroke being measured by one of said position sensors (49, 50) connected to the control unit (51).
