Zusammenfassung:The invention relates to an assembly die, in particular relates to an electron gun assembly die and an assembling method thereof. The electron gun assembly die comprises an upper location die, a cover die and a supporting seat, wherein the upper location die covers and presses on the cover die; and the supporting seat is placed under a cover plate of the gun. Through the whole set of assembly dies of the electron gun and a proper technical operation process, a non-inductive electron-tube heater and a lead electrode can be well contacted so as to avoid current fluctuation or more serious consequences caused by heat emission and ignition of current, ensure concentricity of an emitting surface of the non-inductive electron tube heater, a focusing electrode hole and a shoulder surface of the cover plate of the gun and non-deviated non-defocused electron bunch. The assembly die ensures the interelectrode distance between the emitting surface of the non-inductive electron tube heater and anend surface of a focusing
