Abstract
The application discloses an optical lens interference detection fixing device and belongs to the technical field of optical detection. The device comprises a base, a fixing frame is fixedly installed at the top end of the base, an adapting frame is installed at the inner ring of the fixing frame, a plurality of groups of vacuum adsorption discs are fixedly installed at the inner ring of the adapting frame, the plurality of groups of vacuum adsorption discs are evenly distributed in a circumferential shape along the inner ring of the adapting frame, and an air extraction branch pipe is fixedly installed at the air extraction end of the vacuum adsorption disc. The application places the lens to be detected between the plurality of groups of vacuum adsorption discs, starts a vacuum pump, forms a negative pressure loop in the annular gas collecting pipe through a hose and a connecting pipe, synchronously extracts air from the plurality of groups of vacuum adsorption discs through the plurality of groups of air extraction branch pipes, so that the plurality of groups of vacuum adsorption discs adsorb the edges of the lens, the plurality of groups of vacuum adsorption discs are evenly distributed in a circumferential shape along the inner ring of the adapting frame, multi-point vacuum adsorption is realized, the uniform fixing effect of the lens is improved, the damage to the lens caused by clamping is avoided, and the detection precision and efficiency are improved.
