Abstract
The utility model relates to an assembling die, in particular to an assembling die of an electron gun and an assembling method. The assembling die of the electron gun comprises an upper locating die, a cover die and a support seat, wherein the upper locating die is covered and pressed on the cover die; and the support seat is placed under a cover plate of the gun. By the whole set of the assembling die of the electron gun and the appropriate technological operation, a noninductive filament is in good contact with a lead electrode, so as to prevent the current fluctuation or even more serious consequence caused by current heating and fire striking and ensure the concentricity of a noninductive filament emission surface, a focusing electrode hole and a shoulder surface of the cover plate of the gun, so that the deviation and defocusing of the electron bunch can not be caused; the polar distance between the noninductive filament emission surface and a focusing electrode end surface can be ensured, thereby being favorable for electron emission; in addition, by the die and the right technological operation, the finished product ratio is improved, the parameter requirement of the electron optics can be ensured, and the obvious effects of good part exchangeability of the electron gun and the like can be achieved.
