Abstract
The invention relates to a welding fixture for a vacuum tube and a welding method thereof. According to the welding fixture, the outer diameter of the fixture (1) made of the heat-conducting insulating material is consistent with the inner diameter of the anode cylinder (2), the middle part of the fixture (1) is provided with a through hole (1A) concentric with the outer diameter of the fixture, and the diameter of the through hole (1A) is consistent with the outer diameter of a shielding cover (31) in a filament assembly (3). The invention relates to a method for welding a vacuum tube by using a clamp (1), which comprises the following steps: 1) a clamp (1) with the outer diameter consistent with the inner diameter of the anode cylinder (2) is placed in the anode cylinder (2); 2) placing a shielding cover (31) in the filament assembly (3) into a through hole (1A) which is arranged in the middle of the clamp (1) and is concentric with the outer diameter of the clamp; 3) and welding the filament assembly (3), wherein the filament assembly (3) is welded and then is positioned on the same axis with the anode cylinder. The welding fixture has the advantages of simple structure, convenient operation of the welding method, high efficiency and low cost, and can ensure the service performance of the vacuum tube.
Description
Technical field:
The present invention relates to a kind of weld jig and welding method thereof that is used for vacuum tube, belong to the innovative technology of used weld jig of vacuum tube and welding method thereof.
Background technology:
In the manufacturing process of vacuum tube, the welding of filament assembly is rule of thumb to operate by making the workman, the shortcoming of its existence is that filament assembly welding back occurs and the anode tube situation on same axle center not easily, cause vacuum tube off-centre, so that influence the serviceability of vacuum tube, need reprocess or cause vacuum tube to scrap when serious, both the wasting manpower and material resources, increase production cost, influence production efficiency again.
Summary of the invention:
The objective of the invention is to consider the problems referred to above and a kind of weld jig that is used for vacuum tube simple in structure is provided.
Another object of the present invention is to overcome above-mentioned shortcoming and a kind of welding method of guaranteeing filament assembly welding back and the vacuum tube of anode tube on same axle center is provided.
The present invention is used for the weld jig of vacuum tube, and the external diameter of the anchor clamps made from heat-conducting insulation material is consistent with the internal diameter of anode tube, and the middle part of anchor clamps is provided with the through hole concentric with its external diameter, and the external diameter of the screening cover in the diameter of through hole and the filament assembly is consistent.
The present invention carries out the method that vacuum tube welds with above-mentioned weld jig, includes following steps:
1) in the anode tube, puts into external diameter and the consistent anchor clamps of anode tube internal diameter;
2) screening cover in the filament assembly is put into the through hole concentric that the anchor clamps middle part is provided with its external diameter,
3) welding filament assembly, filament assembly welding back and anode tube are on same axle center.
The present invention has adopted the simple anchor clamps of structure, and guarantee that by anchor clamps anode tube and filament assembly weld after concentric again, thereby on same axle center, solve eccentric problem with the anode tube so can guarantee filament assembly welding back, weld jig of the present invention simple in structure, welding method is easy to operate, the efficient height, cost is low, and can guarantee the serviceability of vacuum tube.
Description of drawings:
Fig. 1 is the structural representation of weld jig of the present invention;
Fig. 2 is the side view of weld jig of the present invention;
Fig. 3 is for carrying out the installation diagram of vacuum tube welding with weld jig of the present invention.
The specific embodiment:
Embodiment:
The present invention is used for the weld jig of vacuum tube, the external diameter of the anchor clamps made from heat-conducting insulation material 1 is consistent with the internal diameter of anode tube 2, the middle part of anchor clamps 1 is provided with the through hole 1A concentric with its external diameter, and the external diameter of the screening cover 31 in the diameter of through hole 1A and the filament assembly 3 is consistent.
The present invention carries out the method that vacuum tube welds with above-mentioned weld jig 1, includes following steps:
1) in anode tube 2, puts into the external diameter anchor clamps 1 consistent with anode tube 2 internal diameters;
2) screening cover in the filament assembly 3 31 is put into the through hole 1A concentric that anchor clamps 1 middle part is provided with its external diameter;
3) welding filament assembly 3, filament assembly 3 welding backs and anode tube are on same axle center.
