The working process of the wheel blank positioning lip correction device is as follows: firstly, the positions of the end mill and the grinding wheel are adjusted according to the outside diameter and width information of a wheel, so that the end mill is located above the positioning lip, and the grinding wheel is opposite to the radial positioning surface of the positioning lip; after feeding on a roller bed, the clamping cylinder is started to drive the rotating wheels to clamp the wheel; then the linear motor I is started to drive the feeding slide plate to descend, the servo motor II drives the end mill to rotate, and the end mill begins milling correction when contacting the axial positioning surface of the positioning lip; when the feeding slide plate descends, the linear motor III is started to drive the outer slide block to be fed horizontally, the servo motor III drives the grinding wheel to rotate, and the grinding wheel begins grinding correction when contacting the radial positioning surface of the positioning lip; after the end mill and the grinding wheel move in place, the servo motor I is started to drive the wheel to rotate at a low speed, and correction is completed after the wheel rotates one circle. Finally, the end mill and the grinding wheel are reset, the wheel is loosened, and the roller bed brings the wheel to next procedure, and so on.
The device is reasonable in layout, flexible and efficient; the two positioning surfaces to be corrected are separated into two stations, so that the interference of cutter concentration is avoided; and through simultaneous correction at the two stations, the production efficiency is high. Besides, the device is high in flexibility and strong in generality, and can be used for correcting wheels having different outside diameters and different widths.
