Title:
OPTICAL LENS SPHERICAL DIAPHRAGM SUPPORT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/078042
Kind Code:
A1
Abstract:
An optical lens spherical diaphragm support apparatus, comprising several support cylinders evenly distributed at the lower end of an optical lens (9). The support cylinders are diaphragm support cylinders (8). Each diaphragm support cylinder (8) comprises a spherical diaphragm (1), a cover plate (3), and a cylinder body (5). The cylinder body (5) has an opening at the upper end and is sealed at the lower end. The edge of the spherical diaphragm (1) is pressed and held at the opening of the cylinder body (5) by the annular cover plate (3), and a screw (2) is used to fasten the cover plate (3) and the spherical diaphragm (1) at the edge of the cylinder body (5), such that the interior of the diaphragm support cylinder forms a sealed cavity; the spherical vertex of the spherical diaphragm (1) is higher than the top of the cover plate (3), and the spherical diaphragm (1) is made of an elastic material having high toughness; the side wall of the cylinder body (5) is provided with an inlet (6) and an outlet (7) respectively used for letting in and discharging a medium inside of the cylinder body. The optical lens spherical diaphragm support apparatus enables height support and pose adjustment during large primary optical lens processing, provides precise, adjustable force support and height support during processing, while absorbing impact on the lens caused by a cutter during processing and enhancing optical lens processing precision.
