AI Technical Summary

Technical Problem

The process of manually tightening the set screw to fix the workpiece in the existing technology is time-consuming, resulting in low production efficiency.

Method used

A protective sleeve is installed inside the mounting hole of the grinding mechanism. The friction between the mounting hole and the protective sleeve is less than the friction between the protective sleeve and the workpiece. The mounting hole and the protective sleeve are designed in a convex shape. The protective sleeve and the workpiece do not move relative to each other. The sleeve enters and exits the mounting hole only on the planetary gear side to facilitate the installation and removal of the workpiece.

Benefits of technology

By designing a protective sleeve and workpiece, wear on the outer diameter of the workpiece is prevented, improving the efficiency of workpiece assembly and disassembly, simplifying the operation process, and increasing production efficiency.

Abstract

The utility model belongs to the field of grinding machine, and relates to a double-end face grinding mechanism for protecting workpiece outer circle, including lower grinding disc, upper grinding disc, a plurality of planetary gears, the planetary gear sets up between lower grinding disc and upper grinding disc, the planetary gear is equipped with a plurality of mounting holes, be provided with the protective sleeve in the mounting hole, be provided with the workpiece in the protective sleeve, the friction between mounting hole and protective sleeve is less than the friction between protective sleeve and workpiece, the mounting hole section is convex, the protective sleeve shape also sets up as convex for the mounting hole, the protective sleeve inside sets up as cylindrical through -hole. The utility model through having the protective sleeve on the workpiece cover, make relative friction occur between mounting hole and protective sleeve, and the relative motion between protective sleeve and workpiece does not produce, thereby avoid the workpiece outer circle to be worn.
