A clamp for processing a special-shaped 3D curved surface and a design method thereof

Abstract

The present application relates to the technical field of glass processing, and particularly discloses a clamp for special-shaped 3D curved surface processing, which has a clamping surface that is adapted to the profile of a workpiece surface, is stable in clamping, has high product size yield, is less likely to scratch the workpiece surface, and has reliable vacuum degree of clamp fixation, and a design method thereof. The design method comprises: selecting a plurality of products, performing profile scanning on the contact parts of each product with the clamp one by one to obtain product surface profile data; fitting and comparing the product surface profile data, and performing trimming to obtain the profile of the product after pre-deformation; performing reverse modeling on the profile of the product after pre-deformation, and designing the clamping surface of the clamp according to the modeled profile; performing hollow design on the clamping surface of the clamp; and setting a sealing ring for abutting against the product surface on the edge of the clamping surface of the clamp. A clamp made by using the above design method is also disclosed.
