Lens spherical surface radian auxiliary detection equipment utilizing homopolar repulsion characteristic

Abstract

The invention relates to the technical field of lens radian auxiliary detection equipment, in particular to lens spherical surface radian auxiliary detection equipment utilizing the homopolar repulsion characteristic. The equipment comprises an equipment main body, a positioning rod is fixedly connected to the front surface of the equipment main body, and a fixing frame is fixedly connected to theright side surface of the positioning rod and located in front of the equipment main body. The upper surface of the positioning rod is fixedly connected with a limiting frame, the upper end of the limiting frame is rotationally connected with a telescopic rod through a shaft, the front surface of the telescopic rod is movably connected with a push rod through a shaft, the clamping force of the lens in the four directions is the same by limiting the lens in the four directions at the same time, and therefore, the lens detection result of the device is improved. The gas in the air cushion is extruded and discharged, the discharged gas treats impurities on the surface of the lens, and the gas accelerates the flow velocity of the surface of the lens, so that the impurities move to a place with a high flow velocity, and the detection efficiency of the equipment can be well improved.

Description

technical field [0001] The invention relates to the technical field of auxiliary detection equipment for lens radians, in particular to an auxiliary detection equipment for spherical radians of lenses using the same-sex repulsion characteristic. Background technique [0002] Lenses: A piece of glass or other transparent material with one or more curved surfaces used to make things appear clear, larger or smaller when viewed through it, usually used in glasses, cameras, telescopes, etc., in the production process of lenses, The curvature of the lens needs to be detected. [0003] However, when the existing equipment fixes the lens, it cannot accurately position and clamp the lens well, and at the same time causes the lens to shift, which may affect the detection results of the equipment. In addition, when the lens is fixed, The impact of external factors on the lens cannot be well excluded, which can affect the flatness of the lens surface; therefore, those skilled in the ar...
