PURPOSE:To realize the indexing at freely selected high-speed by a simple structure wherein a plurality of electron gun assembling sections are installed along a turn table so as to gain enough time to finish the assembling work before a next set of supporting rods are sent to the position opposing to the electron gun assembling section. CONSTITUTION:A pair of the insulated supporting rods 12 and 12 are set in parallel to each other on the outer periphery of the upper surface of the turn table 11 with equal angle interval at the diametrally opposite end position against the position, in which a jig setting section 14 to positioningly support each electrode alignment jig 13 is provided. A plurality of the electron gun assembling sections 17 and 17' are provided with respect to the stop position of the jig setting section 14. The assembling sections 17 and 17' have cradles 18 and 18', hydrogen burners and pivoting arms not shown in the figure respectively. Owing to the structure as described above, the assembling work of the supporting rods 12 at the assembling section 17 can be completed sufficiently during the time in which a plurality of pairs of the supporting rods 12 conveyed by means of the turn table 11 are supplied on one lot to be assembled and, after being assembled, a next lot of the supporting rods 12 is fed to the position opposing to the assembling section 17. |
