Fine polishing machine capable of fine grinding and polishing of special-shaped surfaces

Abstract

The invention discloses a fine polishing machine capable of fine grinding and polishing of special-shaped surfaces. The fine polishing machine comprises a mounting seat, wherein first fixing seats arefixed to the lower end of the mounting seat, a main shaft is rotationally connected to each first fixing seat, a main shaft swinging seat is arranged on one side of the main shaft, a jig is fixed atthe end part of the main shaft, a first belt pulley is in key connection to the middle of the main shaft, and the first belt pulley is in transmission connection with a second belt pulley through a conveyor belt; a speed reducer is arranged on the mounting seat, an input shaft of the speed reducer is in key connection with the second belt pulley, the end part of one end of the main shaft is in keyconnection with a first synchronous wheel, and the first synchronous wheel is in transmission connection with a second synchronous wheel and a third synchronous wheel through a synchronous belt; andthe second synchronous wheel is in key connection with an output shaft of the speed reducer, the third synchronous wheel is key connection with a rotating shaft, the rotating shaft is mounted on the mounting base through a first bearing seat, upper and lower swing mechanisms are arranged on the two sides of the upper end of the mounting seat, and a left and right swing mechanism is arranged on therear side of the upper end of the mounting seat. According to the fine polishing machine, fine polishing of the special-shaped surface lens is achieved, the fine polishing quality is good, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of fine polishing machines, in particular to a fine polishing machine with special-shaped surface fine grinding and polishing. Background technique [0002] Optical glass is mixed with high-purity oxides of silicon, boron, sodium, 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; Lower the temperature 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 into optical lens blanks. In order to meet certain technical requirements, many optical instruments need to further process the optical lens blanks to meet the precision requirements. Therefore, many opti...

Problems solved by technology

[0004] The object of the present invention is to provide a fine polishing machine with special-shaped surface fine grinding and polishing, to solve the above-mentioned background technology. For some lenses with special-shaped surfaces, a special fine polishing machine is needed to realize polishing. Some existing fine polishing machines It does not have the function of fine-polishing special-shaped surfaces, and ordinary fine-polishing machines are often used to polish special-shaped lenses. The polishing quality is poor, the work efficiency is low, and the operation is inconvenient.
