Abstract

The invention discloses polishing equipment for large-diameter optical elements, which comprises a transfer frame, a lifting frame, a positioning tool and a vacuum tank are arranged in the transfer frame, the positioning tool is placed on the lifting frame, a T-shaped hook is arranged on the positioning tool, a universal transfer platform lorry and a horizontal transfer crown block are arranged in the transfer frame, and the vacuum tank is arranged in the transfer frame. A T-shaped groove buckle is arranged on the horizontal transfer crown block; the vacuum tank comprises a tank body, a feeding port formed in the top wall of the tank body, a jacking mechanism arranged in the tank body, a positioning block arranged on the jacking mechanism, a three-axis movement system arranged in the tank body, an ion beam generator arranged on the three-axis movement system, and a hanging frame arranged on a transfer frame located above the tank body. A sealing cover is downwards connected to the hanging frame, and a vacuum pump is connected to the tank body. The optical element polishing device has the advantage that optical elements with the diameter larger than 1500 mm can be clamped, positioned, transported and polished.

Description

technical field [0001] The invention relates to polishing equipment for large-diameter optical elements. Background technique [0002] With the development of the optical industry, the demand for optical components is also increasing, and the demand is also developing from small diameter to large diameter, but the processing equipment in this field is almost monopolized by foreign countries. With domestic breakthroughs in the technical field in recent years, the domestic polishing of small-diameter optical components has become mature, but the ion beam polishing of optical components with large or ultra-large diameters is still blank. At present, the existing domestic equipment can process optical components with a diameter of less than 1500mm. For large-diameter optical components with a diameter of more than 1500mm, there is currently no domestic equipment that can process them. The main reason is that the current domestic optical element lifting and transfer mechanism is...
