AI Technical Summary

Technical Problem

Existing technologies for polishing fluoride crystal rods suffer from problems such as significant material waste, poor stability, easy tilting or vibration of the end face, and uneven distribution of polishing pressure.

Method used

A fixing device including a crystal rod disk and a cover plate was designed. The combination structure of the groove and the cover plate is used to fix the crystal rod. The device is stable through a detachable connector, adaptable to crystal rods of different diameters, and maintains stability during the polishing process.

Benefits of technology

This improved the stability of the fluoride crystal rod polishing process, reduced material waste, decreased the height of the stress point, and ensured the uniformity and precision of the polished surface.

Abstract

The utility model discloses a fixing device for polishing fluoride crystal bars, which comprises a crystal bar disc and cover plates, the crystal bar disc comprises a disc, the outer edge of the disc is provided with a plurality of grooves, the grooves are used for placing crystal bars, and one groove at least corresponds to one cover plate; the cover plate is arranged corresponding to the grooves, the cover plate comprises a main body and second bulges arranged corresponding to the grooves, the end parts of the two sides of the main body are connected with the disc, and the crystal bars in the corresponding grooves are locked through the cover plate. During use, a crystal bar is placed in the groove, the bottom face of the crystal bar slightly exceeds the crystal bar disc, after positioning is completed, the crystal bar is fixed through glue injection, the opening of the groove is covered with the cover plate to be locked, and then the crystal bar and the crystal bar disc can form a whole to be fixed to a polishing machine to polish the end of the crystal bar. The fixing device for polishing the fluoride crystal bar further has the advantages that the polishing process is stable, the stress point height in the crystal bar machining process is reduced, materials are saved, and machining is flexible.
