Displacement adjusting device for optical lens polishing

Abstract

The invention discloses a displacement adjusting device for optical lens polishing. The displacement adjusting device comprises a machine body, wherein a first servo motor is fixed to one side of themachine body; a first lead screw is fixed to an output shaft of the first servo motor; the first lead screw is in threaded connection with a first transmission nut; the first transmission nut is embedded in a first mounting block; a workbench is fixed to the upper end of the first mounting block; first sliding blocks are arranged at two sides of the lower end of the workbench; each first sliding block slides in one first sliding groove; the first sliding grooves are formed in the upper end of the machine body; a lens placing jig is fixed to the workbench; support frames are fixed to two sidesof the machine body; a height adjusting mechanism is arranged at the upper ends of the support frames; a front-back adjusting mechanism is arranged on the height adjusting mechanism; and a grinding head body is arranged on the front-back adjusting mechanism. Through the structure, adjustment of an optical lens in the X, Y and Z directions in the polishing process is achieved, the structure is simple in structure, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of lens grinding displacement adjustment devices, and in particular relates to a displacement adjustment device for optical lens grinding. Background technique [0002] Optical lenses are mixed with high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasonic waves, and removed air bubbles, and then subjected to long-term Slowly cool down over time to avoid internal stress in the glass block. The cooled glass block has excellent properties such as transparency, uniformity, refractive index and dispersion rate, and has been widely used in the field of optical lens technology. In recent years, with the continuous development of science and technology, especially in the fields of biology, electronics, and chemical industry, higher requirements have been put ...
