Unloading and transferring device for correcting plate of large ring throwing machine

Abstract

The invention provides a large-scale annular polishing machine correcting disc unloading transfer device, which comprises a cantilever beam supported by an upright post, wherein the free end of the cantilever beam is provided with a moving slide seat, the center of the moving slide seat is an automatic tracking table seat, a rotary supporter is arranged under the automatic tracking table seat, a support disc is fixedly arranged under the rotary supporter, a plurality of grooves are averagely distributed on the support disc, a plurality of sections of permanent magnet steel are fixedly arranged in each groove through fixing screws, in addition, one magnet steel fixing strip can be fixedly inserted into each groove, a plurality of magnet steel fixing strips are averagely distributed on the upper surface of the correcting disc in the radial direction, a plurality of sections of permanent magnet steel are arranged in each magnet steel fixing strip, and are fixedly arranged on stainless steel embedding elements arranged under the permanent magnet steel through fixing screws, and the automatic tracking table seat automatically tracks the center position of the correcting disc for ensuring the concentric rotation of the support disc and the correcting disc. The large-scale annular polishing machine correcting disc unloading transfer device has the advantages that the non-contact mechanical operation is realized on the large-scale annular polishing machine correcting disc unloading transfer, and the work efficiency and the safety are improved.

Description

technical field [0001] The invention relates to a large-scale ring polishing machine, in particular to an unloading and transferring device for a calibration plate of a large-scale ring polishing machine. Background technique [0002] Ring polishing machine is almost the only large-caliber, global planar optical element processing technology in the world at present. It rotates the workpiece to be polished relative to the polishing rubber disc under a certain pressure and the presence of polishing liquid. The mechanical grinding action and the corrosive action of chemical oxidants complete the material removal on the surface of the workpiece and obtain a smooth surface. Compared with other technologies, this technology can simultaneously achieve local and global planarization of large-diameter workpieces, eliminate high points and waves on the surface of workpieces, eliminate high-frequency defects, and achieve ultra-smooth surface processing quality; planarization The speed...

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.
