Abstract

The invention discloses a rotational lifting mechanism used for quenching of shaft workpieces. The rotational lifting mechanism is characterized by including a vertical frame, on which a lifting screw rod is arranged rotatably and is controlled by a lifting motor. A lifting bench is arranged on and matched with the lifting screw rod. A pneumatic gripper is arranged longitudinally and downwardly on the lifting bench, wherein rotation of the pneumatic gripper is controlled by a rotary motor. The pneumatic gripper can be lifted vertically for inserting one end of a shaft workpiece into an induction coil for quenching the workpiece. By means of control of the lifting motor, quenching length of the shaft workpiece can be controlled. Meanwhile, by means of the rotary motor, the shaft workpiece can be rotated during quenching, thereby improving quenching uniformity and ensuring quenching requirements. The quenching process is free of manual operations and is high in automation degree and quenching efficiency. In addition, the shaft workpieces are longitudinally clamp-held for being quenched, so that defects in a conventional transversally quenching process on the shaft workpieces are avoided and further the quenching quality is improved.
