Problems solved by technology

During the grinding process, because the grinding surface is vertically and equally divided, it is difficult for the debris or powder produced by grinding to be thrown out through the straight groove by the centrifugal force of rotation, and because the surface of the installation head or the surface of the grinding head is concave, it will eventually lead to chipping. Chips or powder are easy to concentrate in the center of the contact surface between the mounting head and the grinding head, resisting the grinding head, making the grinding head unable to fully polish the lens and affecting the accuracy

Abstract

The invention relates to the field of lens processing, and provides a refined lens polishing assembly. According to the technical scheme, the refined lens polishing assembly comprises a mounting head(1), and a polishing head (3), a limiting groove (2) for storing the lens (5) is formed in the mounting head (1), polishing surfaces are arranged on the polishing head (3), a chip outlet duct (11) isarranged at the center of the mounting head (1), each polishing surface is in a block shape and in a fan-shaped arc shape, and an arc groove (34) is isolated between every two polishing surfaces. By means of the refined lens polishing assembly, the fact that the lens (5) is fully and effectively polished is ensured, and the polishing precision is improved.

Description

technical field [0001] The invention relates to the field of lens processing, in particular to a fine lens grinding assembly. Background technique [0002] The existing lens lens radian grinding assembly is composed of a mounting head for placing and fixing the lens and a grinding head matched with the mounting head. The friction surface of the grinding head is provided with a rough grinding surface, and the existing grinding surfaces are all vertically and equally divided. The block-shaped regular grinding surface has a straight groove 32 between the regular grinding surfaces, as attached Figure 1-4 As shown, when the concave surface is polished, the mounting head surface is spherically concave, and the corresponding grinding head surface is spherically convex with the same radian; when the convex surface is polished, the mounting head surface is spherically convex, and the corresponding grinding head surface is spherically concave with the same radian Shape, the installat...
