Abstract

The invention discloses a finish machining device and method for a concave surface of an optical lens. The finish machining device comprises a rack, a polishing assembly, a pressing assembly, a lens tool and a swing assembly used for driving the lens tool to swing. A polishing head comprises an installation base and a polishing ball. The polishing ball is provided with a polishing groove used for polishing the optical lens. The polishing head is arranged to be the polishing ball, and the purpose of machining the concave surface of the optical lens with the large spherical angle is achieved. A cutting edge is formed on the edge of the polishing groove in the polishing ball and used for polishing the optical lens, and cutting chips can be guided out. The swing assembly drives the lens tool to swing on the polishing ball, then a polishing spherical face is formed, and all-round grinding is conducted on the concave surface of the optical lens. The finish machining device is simple in structure, convenient to operate and good in finish machining effect.

Description

technical field [0001] The invention belongs to the technical field of processing optical lenses, and in particular relates to a concave surface finishing equipment and a finishing method of optical lenses. Background technique [0002] The processing of the inner concave surface of the optical lens generally depends on the grinding head for grinding, while the traditional grinding head includes a cylinder and a hemisphere with the same diameter as the top surface of the cylinder, mainly relying on the hemisphere to polish the optical lens, such a grinding head is not convenient for The concave surface with a large spherical degree is polished; and the traditional processing equipment for the concave surface of optical lenses has a complicated structure and complicated processing steps. Contents of the invention [0003] Aiming at the aforementioned deficiencies in the prior art, the present invention provides a concave surface finishing equipment and a finishing method of...
