Patent ID: 10029342

Abstract:
The present invention provides an improved inner-supporting-type online roundness correcting device for a semifinished wheel, which comprises a machine frame, hydraulic cylinders, guide rails, servo motors and correcting wheels. When a bulge of the wheel is met, angles of left correcting wheels II are adjusted through a left servo motor, the left correcting wheels II are kept to be in contact with an inner rim of the wheel all the time and remain stationary in the position, and then, a left hydraulic cylinder enables a left correcting wheel Ito press the bulge of the wheel, so as to recover the roundness of the bulge; and when a depression of the wheel is met, right correcting wheels I are kept to be in contact with an outer rim of the wheel all the time and remain stationary in the position through a right hydraulic cylinder, the angle of a right correcting wheel II is adjusted through a right servo motor, and compressing hydraulic cylinders enable the right correcting wheel II to press the depression of the wheel, so as to recover the roundness of the depression.
