Metal sample automatic replacement system and material tensile strength inspection platform

The invention relates to an automatic metal sample replacement system and a material tensile strength detection platform, and belongs to the technical field of metal mechanical property detection equipment. The automatic metal sample replacing system comprises an auxiliary clamp, a sample placing table and a sample transferring assembly. The two auxiliary clamps are respectively mounted on two clamps of the tensile testing machine, each auxiliary clamp comprises a sleeve with a vertical axis, and a vertically through insertion channel is formed in the outer wall, in the mounting direction of the sample, of each sleeve. The sleeve comprises a large-diameter area and a small-diameter area which are communicated and connected with each other, and the large-diameter area and the small-diameter area correspond to the mounting area and the testing area of the sample respectively. A plurality of samples are placed on the sample placing table, and the sample transfer assembly sequentially transfers each sample to the
