Background

With the rapid development of 3D curved glass in recent years, the traditional processing method mainly for polishing the plane part cannot process a concave workpiece with an edge of 2.5D or 3D curved surface, and the concave polishing machine is produced accordingly. The polishing head is required to be always attached to the side wall and the bottom arc of the concave surface of the 3D glass, and certain pressure is guaranteed. However, the polishing wheel has a certain loss during the polishing process, which requires the equipment to compensate the loss of the polishing wheel. It is therefore desirable to design a device that compensates for the wear of the polishing wheel and allows the polishing wheel to remain in perfect contact with the glass with a constant force. At present, the polishing of the 3D glass concave surface has a polishing wheel self-adaptive floating mode in the aspect of automatic compensation of polishing wheel loss: after the polishing wheel is worn, the polishing wheel or the polishing wheel fixing mechanism is designed into an elastic unit through the mechanical structure design, so that the loss of the polishing wheel is automatically compensated.
