Description

Technical Field

[0001] The utility model belongs to the technical field related to optical lens grinding devices, and specifically relates to a positioning and clamping device for producing and processing optical lenses. Background Art

[0002] Optical lenses are made from a specific mixture of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, and barium, mixed according to a specific formula. The mixture is melted at high temperature in a platinum crucible and stirred using ultrasound to remove bubbles. The glass is then slowly cooled over a long period of time to prevent internal stress in the glass. The cooled glass must be measured using optical instruments to verify that its purity, transparency, uniformity, refractive index, and dispersion meet specifications. However, during optical lens processing, a clamping device is often required. However, existing clamping devices are often inconvenient to install and remove, hindering production efficiency. Patent CN202021589290.5 proposes a positioning and clamping device for optical lens production and processing. Turning a handle activates a turntable that drives a first rotating rod, which in turn rotates a drive disk on the side wall of the first rotating rod. The sidewalls of the drive disk are designed with deep and shallow grooves, allowing the clamping plate to rotate via a support, thereby clamping the optical lens with a clamping block. When the clamping is no longer needed, turning the handle again releases the clamping, facilitating installation and removal. Although this design meets the needs of use to a certain extent, it was found in actual use that this design cannot be effectively connected to the concave and convex lens production equipment during polishing. It can only clamp flat optical lenses and is not suitable for the production of convex and concave lenses. Its practicality needs to be further improved.

[0003] In view of this, the present utility model is proposed. Utility Model Content
