Abstract
The invention relates to a welding method of a vacuum tube. The method comprises the following steps: 1) welding the tube shell (6) and the ceramic connecting piece (5) together through a welding flux, and welding the filament (8) and the support rod (7) together through the welding flux; 2) then, a support rod (7) penetrates through a tube shell (6), a through hole in a ceramic connecting piece (5), a through hole in an end lead piece (4), a through hole in a first clamp (1), a second clamp (2) and a through hole in a third clamp (3), one end of a filament (8) is placed in a groove of the first clamp (1), the second clamp (2) is pressed at a small platform of the support rod (7), a protruding platform at one end of the third clamp (3) is placed in a groove formed in the second clamp (2), and the other end of the third clamp (3) is placed in the tube shell (6); 3) the support rod (7) is welded with the ceramic connecting piece (5) and the end lead piece (4) by using solder. The invention can ensure the distance H1 between the inner wall of the tube shell and the bottom of the filament and the distance H2 between the inner wall of the tube shell and the bottom of the support rod, and can ensure the coaxiality of the tube shell and the filament assembly.
Description
Technical field
The present invention is a kind of welding method of vacuum tube, belongs to the renovation technique of the welding method of vacuum tube.
Background technology
At present, the schematic diagram of vacuum tube welding method as shown in Figure 1, its welding method is: shell 6 and ceramic connecting piece 5 weld together by scolder, filament 8 and pole 7 weld together by scolder, pole 7 is passed the through hole on shell 6, the ceramic connecting piece 5, the through hole on the end leader 4 then, utilize scolder that pole 7 and ceramic connecting piece 5, end leader 4 are welded together then, guarantee that the inwall of shell 6 arrives the distance from bottom H2 of pole 7 to the distance H 1 of filament 8 bottoms and the inwall of shell 6.When in the end a step welds, one end of filament 8 is put into the groove of anchor clamps 1, the internal diameter of groove is identical with the external diameter of filament assembly, anchor clamps 2 are pressed in the chain-wales place of pole 7, play the effect of location, because anchor clamps 2 are to utilize self gravity to push down pole to work, the distance of H1 and H2 is not easy to guarantee, and shell and pole are also eccentric easily during welding, cause the vacuum tube performance bad, and serious will scrap vacuum tube.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of inwall that can guarantee shell preferably to the filament bottom distance H 1 and the inwall of shell to the distance from bottom H2 of pole, can guarantee the welding method of vacuum tube of the axiality of shell and filament assembly simultaneously.
The schematic diagram of vacuum tube welding method of the present invention as shown in Figure 2, the welding method of vacuum tube of the present invention includes following steps:
1) shell (6) and ceramic connecting piece (5) are welded together by scolder, filament (8) and pole (7) are welded together by scolder;
2) then pole (7) is passed shell (6), through hole on the ceramic connecting piece (5), through hole on the end leader (4), first anchor clamps (1), second anchor clamps (2), through hole on the 3rd anchor clamps (3), and an end of filament (8) is put into the identical groove of external diameter of the set internal diameter of first anchor clamps (1) and filament (8), second anchor clamps (2) are pressed in the chain-wales place of pole (7), one end raised platforms of the 3rd anchor clamps (3) is put into the identical groove of raised platforms external diameter of the set internal diameter of second anchor clamps (2) and the 3rd anchor clamps (3), and the other end of the 3rd anchor clamps (3) is put into the internal diameter shell (6) identical with the outside dimension of the 3rd anchor clamps (3);
3) utilize scolder that pole (7) and ceramic connecting piece (5), end leader (4) are welded together, guarantee that the inwall of shell (6) arrives the distance from bottom H2 of pole (7) to the distance H 1 of filament (8) bottom and the inwall of shell (6).
The present invention has increased the stability of anchor clamps owing to adopt the structure that increases anchor clamps 3, can guarantee preferably that the inwall of shell arrives the distance from bottom H2 of pole to the distance H 1 of filament bottom and the inwall of shell, can guarantee the axiality of shell and filament assembly simultaneously.The present invention is a kind of convenient and practical, can guarantee the welding method of vacuum tube of the serviceability of vacuum tube.
