Modular clamping device for forging blade hardness test

The invention discloses a modular clamping device for a forging blade hardness test. The modular clamping device comprises a base, bolts, elastic clamps, a rubber sleeve and a leaf-shaped module, wherein the elastic clamp comprises a gate-type press frame and springs connected to two ends of the press frame; the elastic clamps are fixed on two side surfaces of the base through bolts; the leaf-shaped module is arranged on the base; a to-be-detected blade is arranged in a clamping device main body which is not provided with the leaf-shaped module; a boss in a blade tenon is arranged in a boss groove in the base; the tenon is put into a base tenon clamping groove; the part between the blade and the base is filled and pressed with moist superlight clay, a blade tenon plane is attached to the base tenon clamping groove in parallel and the blade is kept stable to form the leaf-shaped module. The problem of universality of blade toolings with different blade profiles is solved; the condition of selecting special mod
