ABSTRACT:
A crankpin rolling apparatus is provided wherein plural pairs of upper and lower arms are pivotably carried by respective hinge pins extending in parallel relation with the rotational axis of a workpiece support device. A pair of upper and lower roller holders each rotatably carrying burnishing rollers are respectively mounted on each pair of the upper and lower arms. When the plural pairs of upper and lower arms are closed by respective pressuring actuators, the pair of upper and lower roller holders arrest a corresponding one of crankpins of a crankshaft on the workpiece support means and pressure the burnishing rollers upon fillets formed on the corresponding one of crankpins. The hinge pins are respectively carried by a plurality of rocking members, which are independently pivotable about a support shaft held by a machine frame in parallel relation with the rotational axis of workpiece support device. A drive device incorporated in the workpiece support device rotates the crankshaft supported thereon, during which time pivot movements of the rocking members permit the upper and lower roller holders of each pair of upper and lower arms to rotate following a corresponding one of the crankpins. A position control mechanism is further provided for regulating the upper and lower arms to take respective pivot positions suitable for the loading of the crankshaft onto the workpiece support device.
