In order to achieve the above object, the utility model discloses a following technical scheme realizes:

a simple metallographic specimen grinding and clamping device comprises an upper fixing plate, a lower fixing plate, a stud, a fixing rod, a connecting rod, a supporting rod, a connecting disc and a metallographic clip, wherein the upper fixing plate and the lower fixing plate are clamped at the edge of a grinding and polishing machine, and the upper fixing plate and the lower fixing plate are fixedly connected through the stud and a nut; the bottom end of the fixed rod is fixed on the upper fixed plate, the top end of the fixed rod is connected with one end of the fixed rod through a fastener, the other end of the fixed rod is connected with one end of the supporting rod through a fastener, and the other end of the supporting rod is fixedly connected with the connecting disc; the connecting disc is fixedly connected with a plurality of cartridge clips, each cartridge clip consists of a cylindrical part and a bolt, the wall of each cylindrical part is in threaded connection with the bolt, and the bolts are radially and uniformly distributed on the cylindrical parts; the fastener is a bolt and a nut.

And gold phase clips are uniformly welded on the connecting disc.

The double-end stud is more than two.

Compared with the prior art, the beneficial effects of the utility model are that:

simple and easy grinding metallographic specimen clamping device simple structure, easily preparation is applicable to and grinds column metallographic specimen, fixes the device at the edge of grinding the machine of throwing through upper and lower fixed plate, puts into the metallographic specimen and presss from both sides mutually with the gold phase, with the bolt fastening metallographic specimen, adjusts the position of connecting rod, bracing piece and then makes metallographic specimen to suitable grinding position, and rethread fastener fixed link, bracing piece have realized exempting from manual grinding metallography. According to the size and the shape of different metallographic samples, a plurality of metallographic samples are ground simultaneously, the structure is simple and reliable, the use is convenient, the damage to fingers in the grinding process due to the fact that the samples are small is effectively avoided, and the metallographic samples are clamped by gold, so that the clamping is reliable, the metallographic samples are not easy to fall off or fly out to damage other people or experimental instruments, and the method is suitable for both manual grinding and mechanical grinding.
