Embodiment 1

[0032] combined with Figure 1-4 As shown, a welding tool for high-voltage ceramic sealing parts 4 includes a protective box 1 provided with a groove 11 and a protective cover 2 provided with an A through hole 21. The bottom of the groove 11 is integrally formed with a B through hole. The cylinder 3 of the hole 31, the protective cover 2 is installed in the groove 11 of the protective box 1 and the A through hole 21 and the B through hole 31 are coaxial, and the protective cover 2 is provided with a gap 22 , the notch 22 communicates with the A through hole 21 .

[0033] The present invention is a new type of welding tool for high-voltage ceramic seal parts 4. The cylinder 3 in the protection box 1 is used to support the protection cover plate 2, and the groove 11 is used to store clear water for cooling during welding, and the cylinder 3 needs The B through hole 31 is used to install the high-voltage ceramic seal part 4; the A through hole 21 on the protective cover 2 needs ...

Embodiment 2

[0035] On the basis of the above-mentioned embodiments, this embodiment combines the attached figure 2 and 3 Said, further defined, the distance between the two ends of the cylinder 3 is less than the distance between the notch of the groove 11 and the groove bottom of the groove 11, and the diameter of the A through hole 21 is smaller than that of the B through hole 31 close to The diameter of one end of the protective cover plate 2. Wherein the notch of cylinder 3 lower than groove 11 is set, after protective cover plate 2 is installed in protective box 1, protective cover plate 2 can keep in touch with the clear water in groove 11, when carrying out high-temperature brazing, utilize water The volatilization produces steam to cool down the protective cover plate 2 and the melted solder, so that the temperature is not higher than 100 degrees; it is useful to protect the high-voltage ceramic sealing part 4 and the insulating layer in the high-voltage ceramic sealing part 4. ...

Embodiment 3

[0039] On the basis of the above-mentioned embodiments, this embodiment combines the attached figure 2 and 3 As shown, it is further defined that the B through hole 31 is composed of parts A and B and is in a stepped shape, and the part A is close to the protective cover 2 and has a diameter smaller than that of the part B. Wherein the stepped B through hole 31 is set, so that each section of the stepped high voltage ceramic seal part 4 is closer to the side wall of the B through hole 31; because it is closer to the inner wall of the B through hole 31, its own heat is quickly absorbed B The inner wall of the through hole 31 is sucked away, and will not accumulate in the through hole, causing the insulating layer in the high voltage ceramic sealing part 4 to melt due to high temperature.

[0040] Other parts of this embodiment are the same as those of the foregoing embodiments, so details are not repeated here.

Abstract

The invention discloses a high-tension porcelain seal component welding tool and an application method thereof. The high-tension porcelain seal component welding tool comprises a protective box with agroove and a protective cover plate provided with a through hole A. A cylinder with a through hole B is integrally formed at the bottom of the groove. The protective cover plate is separably mountedin the groove of the protective box, and the through hole A and the through hole B are coaxial. The protective cover pale is provided with a notch. The notch communicates with the through hole A. Whenconducting welding on a high-tension porcelain seal component mounted in the welding tool, the welding tool continuously adds clear water into the protective box, heat energy in the welding process is dissipated through evaporation of the clean water to cool the high-tension porcelain seal component. The problem that a porcelain component bears high and low-temperature impact during conventionalwelding and is damaged is solved.

Description

technical field [0001] The invention relates to the field of welding tooling technology, in particular, it relates to the field of welding tooling for high-voltage porcelain seal parts and its application method. Background technique [0002] High-voltage ceramic seal parts are high-voltage resistant and have good insulation performance, and are widely used in high-voltage insulation products. The following method is usually used in the assembly of high-voltage porcelain seal parts. The wires passing through the porcelain parts and the metal blocks placed on the porcelain parts are welded by high-temperature brazing. The welding temperature is about 800 degrees, and the welding time is tens of seconds. In order to prevent the insulating layer of the inner wire of the porcelain part from being melted by high temperature, after the welding is completed, put the high-voltage porcelain seal part into the water to cool down quickly. During high-temperature brazing, the temperatu...
