Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing equipment, in particular to an optical lens fine grinding and polishing device. Background Art

[0002] Optical lenses are made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed in a specific formula. Optical lenses of different thicknesses and angles can play different roles and provide convenience for people's lives. In the processing of optical lenses, lens molding, edge cutting, degree correction, grinding and polishing are required;

[0003] In the process of processing optical lenses, it is usually necessary to use an optical lens fine grinding and polishing device to polish them. When the optical lens fine grinding and polishing device is working, the optical lens to be polished is fixed by a fixture, and then the driving device drives the two polishing wheels to rotate, and then the electric push rod drives the polishing wheel to move, so that the polishing wheel contacts the outer surface of the optical lens, thereby achieving fine grinding and polishing of the optical lens;

[0004] When using the existing optical lens fine grinding and polishing device, although the position of the polishing wheel can be adjusted by an electric push rod, the optical lens can be easily damaged due to the large adjustment range of the electric push rod. Some optical lens fine grinding and polishing devices adjust the positions of two polishing wheels at the same time by coordinating multiple drive motors and adjustment components. Although this reduces the adjustment range, it also makes the internal structure of the optical lens fine grinding and polishing device more complicated and the cost is relatively high. For this reason, we propose an optical lens fine grinding and polishing device. Utility Model Content
