In summary, according to the impact sample clamp provided by the embodiment, the blank 5 is clamped by the blank clamping mechanism 2, so that the blank 5 is processed, and the top of the blank 5 is processed to form the sample 6; the rotation driving mechanism 3 drives the sample clamping mechanism 4 to rotate so as to realize the switching between the abdication state and the clamping state, so that the rotation driving mechanism 3 is in the abdication state when the blank 5 is processed, the interference of the cutter to the processing of the blank 5 is avoided, and the top of the blank 5 is processed into a sample 6; after the sample 6 is obtained by processing, the sample clamping mechanism 4 rotates to a clamping state under the driving action of the rotation driving mechanism 3 and rotates to the sample position to clamp the sample 6, and then the connection between the sample 6 and the blank 7 is cut off by a cutter; after the separation of the sample 6 and the blank 5 is completed, the sample clamping mechanism 4 rotates to a yielding state under the driving action of the rotation driving mechanism 3, namely, the sample clamping mechanism resets, and then the finished sample and the blank are taken away, so that the unloading is realized. After the bar stock is clamped by the impact sample clamp, the processing can be completed once, time is saved, the efficiency is high, the precision is high, and the problems that multiple working procedures are adopted to clamp different clamps respectively and the clamps are time-consuming and labor-consuming to switch in the existing metal material impact sample processing process are solved.
