Full-automatic quartz glass polishing machine

Abstract

The invention discloses a full-automatic quartz glass polishing machine which comprises a framework. A main motor and a spindle are arranged on the framework and are connected with each other by a first transmission mechanism, a polishing support plate is mounted at the upper end of the spindle, a base plate is supported on the polishing support plate, a swing shaft is mounted on a side of the framework, a swing arm is fixed to the upper portion of the swing shaft, a plate press device is fixedly connected to a free end of the swing arm, a miniature motor is arranged on the outer side of the upper portion of the plate press device, an output shaft of the miniature motor is connected with an adjusting lead screw by a second transmission mechanism, the adjusting lead screw is arranged at the upper end of the plate press device, and a positioning output shaft at the lower end of the plate press device is inserted into a center hole of the base plate; a gear motor is arranged on a side of the framework and is connected with a mounting jacket of the plate press device by a crank connecting rod mechanism. The full-automatic quartz glass polishing machine has the advantages that the full-automatic quartz glass polishing machine can be reasonably stressed, torsion on the swing shaft during work can be greatly reduced, accordingly, long-term fault-free continuous work can be guaranteed, and the full-automatic quartz glass polishing machine is long in service life; full-automatic control effects can be realized, and the full-automatic quartz glass polishing machine is high in quartz glass sheet replacing speed and work efficiency.

Description

technical field [0001] The invention relates to a polishing device, in particular to a fully automatic quartz glass polishing machine. Background technique [0002] Quartz glass sheet has high temperature and high pressure resistance, good ultraviolet transmission performance, and extremely low absorption of visible light and near-infrared light. It is the basic material for the production of optical fibers and cannot be replaced by other optical materials. At the same time, its thermal expansion coefficient is extremely small, its chemical stability is good, and its bubbles, stripes, uniformity, and birefringence are comparable to ordinary optical glass. , optoelectronics, military industry, metallurgy, semiconductor, optical communication and other fields. [0003] In order to meet the above-mentioned applications, it is usually required that the quartz glass sheet undergoes processes such as grinding and polishing to achieve a high degree of finish. At present, the poli...

AI Technical Summary

Problems solved by technology

The problems of this polishing machine are: 1. The reciprocating drive mechanism connects the lower end of the swing shaft to drive the swing shaft and the swing arm and the swing platen shaft on the swing shaft to swing back and forth, and the swing platen shaft presses the base during work. The frictional resistance generated between the disc and the polishing disc causes the swinging resistance of the pendulum shaft and the torque it receives is relatively large. After working for a long time, it is easy to cause damage to the reciprocating drive mechanism, bending of the pendulum shaft, and short service life; 2. Manual rotation is required during work. The height position of the swing platen shaft is adjusted by the wheel, the speed of replacing the quartz glass sheet is slow, and the work efficiency is low
