Stable and automatic liquid dropping device for large annular polishing machine

Abstract

The invention discloses a stable and automatic liquid dropping device for a large annular polishing machine. The device comprises a water bucket, a gas pipe, gas stone, a gas pump, a water pump, a water pipe, polishing liquid, a flow adjuster and the large annular polishing machine. The combination of the gas pump, the water pump and the flow adjuster is adopted for the device, heat accumulation is not generated, it is guaranteed that polishing powder in the large-volume polishing liquid is suspended and free of precipitation and the polishing liquid is uniform and stable, the dropwise addingtime of the polishing liquid can be effectively prolonged, the machining quality of optical elements is improved, and it is achieved that the large annular polishing machine stably and automatically perform liquid dropping for a long time. The device is low in using cost, long in service life, easy to achieve, and suitable for the long-time work state of the large annular polishing machine, the frequency for manually adding the polishing liquid is reduced, manual work is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a polishing liquid dripping device, in particular to a stable automatic dripping device for a large ring polishing machine. Background technique [0002] The traditional ring polishing technology is widely used in the planar processing of optical components, especially for the processing of optical components with large diameter and high precision surface shape requirements, a 2.8m ring polishing machine or even a larger size ring polishing machine is required. The polishing liquid used in the polishing process is a mixed solution of polishing powder and deionized water. The traditional way of adding the polishing liquid is to use a brush to pick up the polishing liquid and drop it on the wax plate. With the advancement of technology, the patent In 201310179898.9, the automatic dripping polishing liquid device for ring polishing was applied to the ring polishing technology, and the precise automatic dripping device in the form ...

AI Technical Summary

Problems solved by technology

However, polishing powder is a water-insoluble substance that is easy to precipitate. Neither patent 201310179898.9 nor patent 201811521460.3 fundamentally solves the problem of polishing powder precipitation. Moreover, as the frequency of use of large-scale ring polishing machines increases, the demand for polishing liquids increases. Large, the magnetic stirrer in the patent cannot achieve uniform stirring of large-volume polishing liquid in principle and in the actual use process, and the stirrer in the magnetic stirrer has a short service life and is in contact with the polishing liquid, which makes the magnetic stirrer's ability restricted

The above two patents did not solve the problem of precipitation of polishing powder, so it was impossible to achieve long-term stable automatic dripping

[0003] Solution stirring generally adopts mechanical stirring or ultrasonic stirring. The mechanical stirring equipment uses impeller stirring. The impeller is in contact with the substance, which is large in size, heavy in weight, and inconvenient to operate. During the stirring process, the impeller part is prone to heat accumulation, resulting in a high temperature of the polishing solution. Unstable; ultrasonic stirring is the use of ultrasonic waves in the liquid to cause violent vibrations of liquid particles. This violent interaction between particles can play a good stirring role, but it cannot be stirred into lumps, and ultrasonic stirring is more difficult. It is easy to generate heat accumulation, resulting in unstable polishing fluid and affecting the processing quality of optical components
