Abstract

An automatic gage head positioning system especially adapted for CNC grinding of reciprocating engine crankshaft journals. The system incorporates an actuated four-bar linkage mechanism for accurately controlling the path of a gage device between disengaged and gaging positions. A lost motion rotational coupling is provided to enable the gage to follow the position of the crankshaft journal during machining. A counterspring assembly positioned in the gage system base partially opposes gravity to provide precise control of the actuation force between the gage and the workpiece journal.
