Problems solved by technology

[0003] For large-size and ultra-thick optical lenses, after the rough blank is manufactured, its end face needs to be polished, and it needs to be clamped and fixed before grinding. The existing fixing device is inconvenient to use, and the During the process, it is fixed by the splints on both sides. When fixing, the radian of the clamping cannot be automatically adjusted according to the diameter of the optical lens. At the same time, the splint cannot fit the surface of the optical lens well, resulting in clamping and fixing. The effect is not good

Abstract

The invention discloses a clamping and fixing device for grinding the end face of an ultra-thick optical lens. Placed on the placement seat, the gravity of the optical lens itself makes the placement seat drop, and the first connecting rod pulls the sliding seat to move. During the movement of the sliding seat, the support rod drives the clamping seat close to the optical lens to clamp it. Fixing, during this process, start the electromagnet, the repulsive force between the electromagnet and the permanent magnet plate drives the permanent magnet plate and the movable rod to move towards the direction close to the optical lens, so that the base drives the arc-shaped splint to fix and clamp the optical lens.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a clamping and fixing device for grinding the end face of an ultra-thick optical lens. Background technique [0002] Optical lenses are mixed with high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves, and removed air bubbles; Slowly cool down over time to avoid internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form Optical lens blanks. [0003] For large-size and ultra-thick optical lenses, after the rough blank is manufactured, its end face needs to be polished, and it needs to be clamped and f...
