The universal shaft is used for bearing a processing workpiece by the tapered roller bearing and realizing a rotating function; the cylindrical roller bearing realizes the translation function of a machined workpiece. The piston rod of the oil cylinder realizes the lifting and descending functions of the universal shaft. When the device works, a processing workpiece is placed on the correction platform, an oil cylinder piston rod in the platform adjusting device lifts the workpiece through the universal shaft, the bottom surface of the workpiece is higher than the correction platform, the workpiece pushing device pushes the workpiece to move, the tapered roller bearing and the cylindrical roller bearing rotate and roll to move according to the stress state of the processing workpiece when the processing workpiece moves, until the datum plane of the processing workpiece is attached to the positioning surface of the workpiece positioning device to finish the positioning of the processing workpiece, the oil cylinder piston rod of the platform adjusting device descends, the top surface of the universal shaft bearing falls below the upper plane of the correction platform, the bottom surface of the processing workpiece is attached to the upper plane of the correction platform, and the correction of the processing workpiece is finished.
