Auxiliary device for metallographic sample preparation of aluminum-clad steel single wire

The utility model relates to the technical field of metallographic sample preparation of aluminum-clad steel single-wire leads, in particular to an auxiliary device for metallographic sample preparation of aluminum-clad steel single-wire leads, which comprises a funnel ring, a mounting ring is fixedly connected to the bottom end of the funnel ring, and a stabilizing plate is fixedly connected to the top surface of the mounting ring. A wire fixing hole and a second leakage hole are sequentially formed in the surface of the stabilizing plate from left to right, and the second leakage hole is semicircular. And the first leaking hole is formed in the stabilizing plate. By embedding a plurality of aluminum-clad steel single-wire leads at one time, the metallographic sample preparation efficiency and reliability can be improved, the sample preparation construction period and the detection construction period are effectively shortened, the measurement accuracy is ensured, the test detection rate is improved, the aut
