Clamping workbench based on special-shaped part machining

The clamping workbench comprises a base, a rotatable mounting disc is arranged in the middle of the base, a supporting part used for machining the special-shaped parts is arranged on the upper surface of the mounting disc, and a plurality of first clamping mechanisms used for laterally clamping the special-shaped parts are arranged on the upper surface of the supporting part; the multiple first clamping mechanisms are distributed in an annular array mode, each first clamping mechanism comprises two first fixed sliding rails and a mounting plate, and the two first fixed sliding rails are fixedly mounted on the upper surface of the supporting part. Through rotation of the two first contact pressure heads and inclination change of the mounting plate, clamping points of the two first contact pressure heads are tightly attached to the outer wall of the special-shaped part, the problem that the special-shaped part is difficult to clamp is solved, and meanwhile stability is high. 本发明公开了基于异形件加工的装夹工作台，包括基座，所述基座的中部设置有可
