ABSTRACT:
A loader (10) for a grinding machine includes a loading member (30) with at least one resilient finger (32) thereon for gripping a workpiece (14) to be ground by movement of the loading member in a loading direction as a resiliently biased workpiece positioner (34) initially counteracts force applied to the workpiece by finger deflection. Continued movement of the loading member (30) after the gripping first moves the workpiece positioner to a nonblocking position and thereafter moves the workpiece to an associated grinding machine. Preferably, a pair of the fingers (32) and a rigid locator (44) cooperate to position and grip a joint race (14) of an annular shape with ball grooves to be ground. A pair of spring biased blocking members (34) preferably embody the workpiece positioner and are pivotally mounted in alignment with a hopper (16) in which workpieces to be ground are stocked. The loading member (30) is supported on a movable carriage (150) that is pivotal about a vertical axis on a fixed base (148) between use and access positions. An unloading chute (20) also supported on the fixed base has a movable floor section (182) that is extended to receive each workpiece after it is ground and thereafter retracted to prevent interference with the grinding wheel during the next cycle.
