The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Embodiment 1, referring to fig. 1 to 4, a floating positioning device suitable for stamping die sheet metal parts comprises a lower die base 1, lower die male dies 2 and a floating positioning mechanism 3, wherein two groups of lower die male dies 2 are symmetrically arranged on the surface of the lower die base 1, the floating positioning mechanism 3 is fixedly arranged on two sides of each lower die male die 2, the floating positioning mechanism 3 comprises an ejector block 4, an ejector rod 5, a stop block 6, a coil spring 7 and a mounting plate 8, the upper end of the ejector rod 5 penetrates through the mounting plate 8 and is fixedly connected with the ejector block 4, the lower end of the ejector rod 5 is fixedly pressed on the upper end of the coil spring 7 through the stop block 6, the lower die base 1 is provided with a spring nest 11 for mounting the coil spring 7 corresponding to the floating positioning mechanism 3, the mounting plate 8 is provided with a positioning hole 9 for fixedly connecting a screw with the lower die base 1, the coil spring 7 is fixedly mounted in the spring nest, then the lower end of an ejector rod 5 sleeved on the mounting plate 8 is pressed on the upper end of a spiral spring 7 through a stop block 6, and then the mounting plate 8 is fixed on the lower die holder 1 through screws.

Referring to fig. 4, the ejector block 4 is in a long strip shape, and an L-shaped notch 10 is arranged at the far end of the ejector block 4, so that the sheet metal part can be positioned conveniently by using a side edge or a small convex surface, and the sheet metal part can be positioned accurately.

Referring to fig. 1, an upper die insert 12 (not shown) is fixedly disposed on the upper die base corresponding to the floating positioning mechanism 3.
