Description

Technical Field

[0001] The utility model relates to the technical field of lens clamping tooling, in particular to a clamping tooling for processing concave-convex lenses. Background Art

[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.). Convex lens: thick in the middle and thin at the edges, there are three types: biconvex, plano-convex, and concave-convex; concave lens: thin in the middle and thick at the edges, there are three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in astronomy, military, transportation, medicine, art and other fields. When processing lenses, the lenses need to be polished to make the lenses polished to the appropriate size.

[0003] However, when grinding the edge of the lens, the traditional clamping tool adopts a fixed method, and the grinding equipment needs to rotate around the lens. However, in this method, since the lens grinding equipment is relatively large, the larger grinding equipment consumes more energy when rotating than the lens rotation. When the clamping tool rotates, the lens is not stable enough, and the lens needs to be clamped by hand, which makes the lens processing time-consuming. Utility Model Content
