Description

Base device for increasing machining range and lens grinding and machining equipment Technical Field The present application relates to a lens processing device, and more particularly, to a base device for increasing a processing range and a lens polishing device. Background The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. Along with the wider and wider application of various optical lenses in various fields, the requirements on various indexes of the optical lenses are higher, the processing difficulty of the lenses is also improved in the design of optical paths in order to continuously improve the overall lens effect, the processing difficulty is increasingly improved mainly in the specificity of materials and opening angles, the opening angle structure of the lenses is also deviated from two end limits in the application of the design of the optical paths, and the optimal half opening angle of the lenses is 18-38 degrees. In the prior art, most of the lens processing equipment is designed in an optimal 18-38 DEG state at the initial stage of design, the center of the upper surface of the adapter of the common processing equipment is provided with a cylindrical extension wall, a groove is arranged in the middle of the extension wall, the convex part of the grinding tool is placed in the groove, and then the bolt is meshed with a threaded hole which is radially arranged in the extension wall and penetrates through the groove to fix the bolt.
