Problems solved by technology
[0003] Most of the existing spectacle lens edging machines clamp the lens during the edging process, and the lens is polished by driving the lens to rotate. The existing edging machine lacks a relatively accurate positioning device, resulting in the clamping during edging. The tight part is not in the center of the lens, wearing this kind of glasses will accelerate the increase of the wearer's myopia
[0004] The technical solution provided by the patent document CN206967196U only solves the problem of no shaking during lens processing, but does not solve how to realize center positioning

The invention relates to the field of optical lens edging equipment, and discloses an edging device for an optical lens. The edging device comprises a first clamping rod and a second clamping rod. Matched pressing heads are arranged at the opposite ends of the first clamping rod and the second clamping rod. The other end of the first clamping rod is rotationally connected with a first bearing pedestal, and the second clamping rod penetrates through a rotationally connected second bearing pedestal and is in transmission connection with a driving mechanism on one side of the second bearing pedestal. An auxiliary positioning device is arranged on the side, close to the pressing heads, of the second bearing pedestal. The lens is firstly attached to the pressing head on the second clamping rodbefore being fixed; due to the fact that the depth of a sleeve opening of a positioning sleeve is larger than the length of the pressing heads, the pressing heads and the lens are all located in the positioning sleeve at this moment, and the edge of the lens gradually touches and squeezes positioning blocks in the rotating process of a locking sleeve; and when the lens is locked, due to the synchronous movement of the multiple positioning blocks, the center of the lens is in contact with the pressing heads on the two sides, and therefore the lens is accurately positioned.
Description
technical field [0001] The invention relates to the field of optical lens edging equipment, in particular to an edging device for optical lenses. Background technique [0002] With the increase in the number of myopia people, the number of wearers of glasses is also increasing. Before assembling glasses, optical shops will polish the round lenses and finally install them. [0003] Most of the existing spectacle lens edging machines clamp the lens during the edging process, and the lens is polished by driving the lens to rotate. The existing edging machine lacks a relatively accurate positioning device, resulting in the clamping during edging. The tight part is not in the center of the lens, and wearing this kind of glasses will accelerate the increase of the wearer's myopia. [0004] The technical solution provided by the patent document CN206967196U only solves the problem of no vibration during lens processing, but does not solve how to realize center positioning.
