Machine tool for grinding outer edge of optical lens Technical Field The invention relates to the technical field of forming machine tools, in particular to a machine tool for grinding the outer edge of an optical lens. Background The optical instrument is composed of a single or a combination of a plurality of optical devices. The optical instruments are mainly divided into two major categories, namely optical instruments for imaging, such as slide projector, camera and the like, and optical instruments for imaging, such as telescope, microscope, magnifying glass and the like, wherein the optical instruments are very important component categories in the instrument and meter industry, and are indispensable tools for observation, test, analysis, control, recording and transmission in various fields of industrial and agricultural production, resource exploration, space exploration, scientific experiments, national defense construction and social life. In particular, the function of modern optical instruments has become an extension and expansion of the human brain nerve function. The optical lens is an indispensable part of an optical instrument, is divided into a plurality of types according to different shapes and functions, such as a plane mirror, a spherical mirror, a lens and the like, and the optical lens on the optical instrument is a core component of the optical instrument and plays a key role in regulating and controlling an optical path, improving imaging quality and guaranteeing stable operation of a system, and is a decisive factor for performance, reliability and application range of the optical instrument. The outer edge grinding of the optical lens is usually a subsequent procedure performed after finishing the main curved surface grinding in the central area of the lens, and the main purposes are to trim the edge shape, remove burrs and cracks, reach the diameter required by design, ensure the flatness and safety of the edge, ensure the lens to reach the accurate assembly size, ensure the lens to be tightly screwed into the lens barrel or the ferrule, and avoid scratches or cracks and the like in the subsequent assembly or use. The grinding of the lens by using the numerical control edging machine requires manual mounting and fixing of the lens, namely manual feeding, but the optical lens is thin and has a small majority of diameters, the whole volume is small, the manual feeding is more inconvenient and has a certain risk of collision or even falling, so that the lens is damaged, in addition, the lens is ground by firstly locking the position of the lens, the most common method is to heat and melt a small amount of special optical positioning wax, the method can avoid damage to the lens to the greatest extent, but after grinding is finished, the wax is heated gently to soften the wax, and then the lens can be carefully taken down, so that the processing efficiency is influenced, and the wax liquid is easy to remain on the lens to pollute the lens, thereby increasing the subsequent cleaning burden.
