Calibration disc unloading and load-transferring device of large ring polishing machine

Abstract

The invention provides a calibration disc unloading and load-transferring device of a large ring polishing machine and relates to a calibration disc unloading and load-transferring device which is used for assisting surface precision polishing on the large ring polishing machine and large in weight. The calibration disc unloading and load-transferring device mainly comprises a tensile force adjusting spring for providing power, wherein the spring is connected with one end of a lever through a pin, a supporting point is arranged at the other end of the lever, a cross-shaped knife edge, a hanging bracket and a spherical joint are sequentially arranged under the supporting point, and the spring tensile force acts on the hanging bracket through the cross-shaped knife edge. The hanging bracket is of a multiple-jaw-shaped structure, a distribution disc is arranged on each extending jaw arm, each distribution disc pulls a copper sleeve inlayed in a calibration disc through a steel wire and a pulling steel ball, and accordingly the tensile force is transferred to the calibration disc. The calibration disc unloading and load-transferring device can achieve mechanized operation of calibration disc unloading and load transferring of the large ring polishing machine, reduce the labor intensity of workers and improve the working efficiency, is simple in structure and convenient to operate, greatly improves the safety in the calibration disc unloading and load transferring process and avoids outside impurities.

Description

Technical field [0001] The invention relates to an optical element surface or microelectronic wafer polishing equipment, in particular to a large-scale ring polishing machine for accurately polishing the surface of large-size optical glass components, especially for assisting large-diameter glass workpieces on the large-scale ring polishing machine to perform surface precision polishing A device for unloading and transferring of the calibration disk. Background technique [0002] The ring polishing machine is almost the only large-diameter, globalized planar optical element processing technology in the world. It rotates the workpiece to be polished relative to the polishing rubber disk under a certain pressure and the presence of polishing liquid, and uses abrasive particles. The mechanical grinding action and the corrosive action of the chemical oxidant complete the material removal on the surface of the workpiece and obtain a smooth surface. Compared with other technologies, t...

AI Technical Summary

Problems solved by technology

Most of the current unloading and transferring devices for the calibration discs of ring polishing machines are miniaturized carts, and there are few devices for unloading and transferring large-diameter calibration discs; Less oil and other pollutants are introduced, which is not conducive to the surface finish index of the workpiece. When the calibration plate is reloaded, the worker needs to push it to complete the reloading of the calibration plate, which will also introduce unnecessary external impurities.
