The utility model relates to the technical field of turbine blade machining clamps, in particular to a low-pressure turbine working blade and blade crown integrated machining clamp which comprises a base, a first fixing piece and a second fixing piece, and the first fixing piece and the second fixing piece are arranged on the base. The first fixing piece is fixedly arranged on the base. The second fixing piece is arranged on the base and can move relative to the first fixing piece. The first fixing piece and the second fixing piece are arranged in a matched mode so that the first fixing piece and the second fixing piece can clamp the turbine blade. The base is provided with a fixing hole matched with a machine tool so that the base can be fixed to an objective table of the machine tool. After the low-pressure turbine working blade and blade crown integrated machining clamp clamps a turbine blade, multiple faces of the turbine blade can be machined under rotation of the objective table, and frequent clamp swit
