Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in FIGS. 1-2;

the utility model discloses a profile steel rim vertical lathe clamp, which comprises a clamp base 1, a main shaft 2 and a clamp body 3;

the fixture body 3 is arranged on the fixture base 1;

the tensioning disc 4 is driven to move up and down in the clamp body 3 through an oil cylinder piston 14 in the inner cavity of the main shaft 2; specifically, the upper end of a cylinder piston 14 in the inner cavity of the main shaft 2 is fixed at the center of the tension disc 4 through a connecting screw 13;
