Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a locking type clamping fixture for polishing optical lenses. Background Technology

[0002] Optical lenses are lenses made of optical glass. During the manufacturing process, after the lenses are cooled and shaped, they need to be polished using polishing equipment.

[0003] Existing polishing fixtures typically use bolts to fix the fixture to the polishing machine, and then a threaded clamping mechanism to hold the optical glass in place. However, during the clamping process, because the clamping mechanism cannot be positioned precisely, the operator must first position the lens before clamping and fixing it, resulting in poor performance. Furthermore, after polishing, the thinness of the lens makes it difficult for the operator to remove it from the fixture, making material retrieval inconvenient. Therefore, we propose a locking-type optical lens polishing fixture. Utility Model Content
