Further, the first clamping plate 21 and the second clamping plate 22 of each clamping unit 2 are provided with anti-skid rubber pads on the sides close to each other.

In the above embodiment, the antiskid rubber pad that sets up can improve the fastening degree when first splint 21 and second splint 22 press from both sides tight metallographic specimen, still can reduce the risk of destroying metallographic specimen when pressing from both sides tight metallographic specimen simultaneously.

Further, as shown in fig. 2 and 3, the number of the gripper units 2 is six.

In the above embodiment, the fixing and polishing operations of the plurality of metallographic samples can be simultaneously performed by the above arrangement.

As shown in fig. 5, the present application provides a sample tray 8, which is applied to the fixing mechanism of the metallographic sample polishing machine of the first aspect. The device comprises a tray 8 with the diameter the same as that of the sample mounting disc 1, and supporting blocks 9 with the same number as that of the clamping units 2 are arranged above the tray 8.

In the above embodiment, the supporting block 9 above the tray 8 can be used for placing the metallographic specimen, so that technicians can conveniently place the metallographic specimen at the same height, and thus when all the metallographic specimens are fixed by using the driving disc 3 to drive all the clamping units 2, all the metallographic specimens can be fixed at the same position, and the depth of subsequent polishing is guaranteed to be consistent.

Further, as shown in fig. 5, the distance between the adjacent supporting blocks 9 is equal to the distance between the adjacent first clamping plates 21, and the distance from the outer side of the supporting block 9 to the center point of the tray 8 is equal to the distance from the inner side of the first clamping plate 21 to the center point of the sample mounting plate 1.
