[0005] When using the optical lens production system in the prior art, when cutting the optical lens, the optical lens is clamped by the first clamping block and the second clamping block, thereby polishing the optical lens, but in practical applications, the blank usually It is a cylinder, so it is only fixed by two clamping blocks. When the machine tool is milling, the force exerted on the blank will easily cause the blank to move, resulting in a change in the size of the optical lens, which needs to be improved

The invention discloses a fixed tooling for light-weight milling of optical lens blanks, which relates to an auxiliary device for milling optical lens blanks, aiming to solve the problem of insufficient positioning of blanks in the prior art during milling, which is prone to movement and causes optical lens The technical problem of dimensional error, the key points of the technical solution include the chassis set on the workbench and the fixing seat set on the chassis, the fixing seat is provided with several positioning components for clamping the blank, the fixing The seat is equipped with a distance adjustment assembly for adjusting the positioning assembly; when milling the blank, first fix the chassis on the workbench, then place the blank on the fixed seat, adjust the positioning assembly through the distance adjustment assembly according to the size of the blank, and then The blank is clamped by a plurality of positioning components, so that the blank can be fixed on the fixed seat, which is beneficial to reduce the possibility of the blank moving when the blank is milled, and the possibility of changing the size of the optical lens when the blank is milled.
Description
technical field [0001] The invention relates to an auxiliary device for milling an optical lens blank, more specifically, it relates to a fixed tool for lightweight milling of an optical lens blank. Background technique [0002] Optical glass is mixed with oxides of high-purity 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; The temperature is lowered slowly over time to avoid internal stress in the glass block. The cooled glass blocks 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, which are usually columnar. [0003] Tooling, that is, process equipment: refers to the general term for various tools used in the manufa...
