Title:
AUTOMATIC GAGE HEAD POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO2001070456
Kind Code:
A3
Abstract:
An automatic gage head positioning system (10) especially adapted for CNC grinding of reciprocating engine crankshaft journals (22). The system (10) incorporates an actuated fourbar linkage mechanism for accurately controlling the path of a gage device (12) between disengaged and gaging positions. A lost motion rotational coupling is provided to enable the gage (12) to follow the position of the crankshaft journal (22) during machining. A counterspring assembly (50) positioned in the gage system base (38) partially opposes gravity to provide precise control of the actuation force between the gage (12) and the workpiece journal (22).
