Abstract

A pair of adjustable crankpin locators (40,100) for use on a crankshaft grinding machine (20) is disclosed. The adjustable crankpin locators (40,100) permit a size range of crankshafts (78) to properly be located in the grinding machine (20). One locator is an adjustable vee block locator (40) wherein the sides of the vee block are relatively positionable to accommodate a range of crankshafts (78) having different throws and different crankpin diameters. A supporting assembly (42) is provided on the crankshaft grinding machine (20) for supporting the adjustable vee block locator (40) in position to properly locate one crankpin (80) on the crankshaft (78) to be ground. An adjustable stud crankpin locator (100) is also provided for locating the crankshaft (78) in proper position, after the first crankpin (80) is ground, for grinding a 180.degree. displaced second crankpin (82). The adjustable stud crankpin locator (100) can also accommodate a range of crankshaft sizes. Interlocks are provided to assure locators (40,100) are in a remote parking bracket before grinding machine (20) can operate.
