Casing part inter-process remodeling clamp and method

The invention discloses a remodeling clamp and method for cartridge receiver part working procedures. The remodeling clamp comprises a base. A plurality of positioning spigot devices are arranged on the base; the positioning spigot device comprises a positioning pin, a supporting rod, a pressing plate, a positioning spigot and a nut; a plurality of positioning spigots with different sizes are sequentially arranged on the base from inside to outside; a supporting rod is fixedly arranged on one side of each positioning spigot; a pressing plate is arranged at the top of the supporting rod and used for fixing a part to the positioning spigot. A nut is arranged on the top of the supporting rod. The quick remodeling method for machining the same part in the adjacent working procedures or different parts in the different working procedures on the same machine tool can be quickly achieved, when the remodeling clamp is used for machining the part, the same clamp can be used for clamping and positioning in the two or m
