ABSTRACT:
A radial locator is carried by the bed of a cam lobe grinding machine proximate the workpiece chuck. An initial locating pin is carried by the chuck to sense a rough locating hole in a sprocket carried by a cam shaft to be disposed in the chuck to have its cam lobes ground. A timing tooth is provided on the sprocket in proper proximity to the rough locating hole and for coaction with complimentary locating teeth carried by a rockable locating arm of the radial locator. An actuating arm carries the locating arm for movement between an at rest disposition and a rocked disposition wherein the locator teeth coact with the timing tooth to rotate the sprocket, cam shaft and cam lobes to a final position for proper grinding of the cam lobes. A rotary actuator moves the actuating arm an locating arm between their respective dispositions.
