Abstract

A portable metallographic sample grinding machine comprises a base, a planet wheel, a planet carrier, a sun wheel, a supporting seat, a rotary shaft, a support, a crank, a weight, a servo motor and asample limiting ring. The planet carrier and the sun wheel are mounted on the supporting seat through bearings, and the planet wheel, the planet carrier and the sun wheel constitute a planet wheel transmission system together with the base. The bottom face of the supporting seat and the bottom face of the base are located on the same horizontal plane, and the support is mounted above the base. Thecrank or the servo motor is mounted above the support and connected with the sun wheel through the rotary shaft. The portable metallographic sample grinding machine is portable, easy and convenient to operate, flexible in operating and low in cost, the requirements of school teaching and researchers for metallographic grinding can be met, the problems of uneven stress, the cambered surface and alarge number of deep scratches during a metallographic manual grinding test can be effectively avoided, the labor intensity of students or the researchers or the like is reduced, and the metallographic grinding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to laboratory metallographic sample grinding equipment. Background technique [0002] In order to observe the metallographic microstructure, the sample is generally cut and inlaid to prepare a metallographic sample, and then the surface is polished. At present, the laboratory mainly adopts two methods for grinding metallographic samples. One is manual grinding with sandpaper. Because the sample is small and irregular, manual grinding takes a long time and the sample has no limit device, which is easy to cause finger soreness. There are many planes or curved surfaces on the surface of the sample and many deep scratches, which are not conducive to the observation of the microstructure; the other is to use a desktop metallographic grinder for grinding, which is relatively large and The cost is high, it cannot be moved and used flexibly at will, and it is a waste of energy. ...
