In order to achieve the above purpose, the utility model adopts the following technical scheme:
clamping device is thrown to metallographic specimen mill includes: the test device comprises a support, a hand wheel, a trapezoidal screw rod, a connecting plate and a sample embedding plate, wherein a screw rod supporting plate is fixed on the support, screw rod nuts are fixed on the screw rod supporting plate and the connecting plate, the upper end of the trapezoidal screw rod is fixedly connected with the hand wheel, the lower end of the trapezoidal screw rod penetrates through the screw rod nut on the screw rod supporting plate and then is fixedly connected with the screw rod nut on the connecting plate, and a spring is arranged between the connecting plate and the sample embedding; and a plurality of embedding holes for installing metallographic samples are formed in the sample embedding disc.
Among the above-mentioned technical scheme, it is further, sample inlay dish, connecting plate on correspond and be equipped with a plurality of pairs of mounting holes, every mounting hole is used for the erection joint pole, the mounting hole screw-thread fit of dish is inlayed with the sample to the connecting rod lower extreme, in the mounting hole of connecting plate is inserted to the upper end, the nut screws, the spring housing establish on the connecting rod.
The utility model discloses the beneficial effect of device lies in:
the utility model discloses a metallographic specimen grinds throws clamping device of independently designing can realize handling the metallographic specimen of a plurality of different diameters simultaneously. The hand wheel drives the trapezoidal lead screw to feed, so that the compaction between the sample and the grinding disc can be realized, and the positive pressure required by grinding and polishing is provided. And install the spring between connecting plate and sample inlay dish, can make the sample atress more even, improve the surface quality who obtains of processing.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
the metallographic specimen grinding and polishing clamping device comprises a specimen embedding disc 2, a plurality of springs 3, a connecting plate 4, a hand wheel 6, a trapezoidal screw 7, a screw supporting plate 9, an aluminum profile bracket 10, a plurality of connecting rods 11, a circular flange nut a 5, a screw nut a8, a circular flange nut b12 and a screw nut b 13;
referring to fig. 1, a screw support plate 9 is fixed on an aluminum profile bracket 10 by a socket head cap screw. The hand wheel 6 is fixedly connected with the trapezoidal screw 7 through threads.
