Problems solved by technology

During the rounding process, the ground glass shavings have nowhere to transfer and can only stick to the grinding wheel, and adjacent grinding wheels will also move axially and squeeze each other to increase wear, which will affect the appearance quality of the glass ground by the grinding wheel

Embodiment

[0015] As shown in the accompanying drawings, a cutting tool of a lens rounding machine is provided with a grinding wheel 2 on the rotating shaft 1, and the grinding wheel 2 includes a plurality of sub-grinding wheels 3 arranged coaxially, and the meshes of the sub-grinding wheels 3 increase sequentially along the axial direction; A spacer 4 is arranged between the sub-grinding wheels, and the outer diameter of the spacer 4 is slightly smaller than that of the adjacent sub-grinding wheels.

[0016] Further, the mesh numbers of the sub-grinding wheels 3 are respectively 240 mesh, 360 mesh, and 500 mesh respectively, and the diameter of the sub-grinding wheels increases with the increase of the mesh number. When in use, the lens square column to be rounded is ground successively by 240-mesh, 360-mesh, and 500-mesh grinding wheels, and the diameter of its circumscribed circle becomes smaller along the axial direction. The front and rear parts of the lens square column can be well...

Abstract

The invention relates to a lens rounding machine cutter, comprising a grinding wheel arranged on a rotating shaft, wherein the grinding wheel comprises a plurality of sub grinding wheels which are coaxially arranged; the quantity of the sub grinding wheels is sequentially increased along the axial direction and a gasket is arranged between the adjacent sub grinding wheels; and the outer diameter of the gaskets is slightly smaller than that of the adjacent sub grinding wheel. According to the lens rounding machine cutter disclosed by the invention, the gaskets are arranged between the adjacent sub grinding wheels and the outer diameter of the gaskets is slightly smaller than that of the adjacent sub grinding wheel, so that grinded glass dust can naturally move to a gap between the adjacent grinding wheel and the corresponding gasket along the movement of a lens column and the appearance quality of glass grinded by the grinding wheel is not influenced; and the gaskets also have the effect of buffering and absorbing vibration so that the abrasion caused by mutually extruding due to axial movement of the adjacent sub grinding wheels is lowered, so that the appearance quality of the grinded glass is further ensured.

Description

technical field [0001] The invention relates to a glass lens processing equipment, in particular to a lens rounding machine tool. Background technique [0002] In the preparation process of optical lenses used in digital cameras, CCD cameras and other equipment, the raw materials need to be cut into middle pieces, glued and then cut into glass square columns in batches and then rounded by a rounder. At present, the cutting tools of the round grinding machine generally use a plurality of grinding wheels from coarse to fine, and adjacent grinding wheels are close together. During the rounding process, the ground glass shavings have nowhere to transfer and can only stick to the grinding wheel, and adjacent grinding wheels will also move axially and squeeze each other to increase wear, which will affect the appearance quality of the glass ground by the grinding wheel. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a lens ...
