Description

Technical Field

[0001] The utility model relates to the technical field of casting repair, in particular to an infiltration vacuum welding repair device. Background Art

[0002] The micropore defects of pressure-bearing castings seriously affect the compactness of the castings, and in severe cases, the castings will be scrapped. Casting impregnation repair is the simplest and most effective repair method to solve the leakage. Impregnation is to infiltrate the pores of the casting with a colloidal impregnant, and then solidify the impregnant and connect it with the inner wall of the casting pores to achieve the purpose of plugging the leak. The existing impregnation method uses local brushing of the impregnant on the tiny pinholes, but it cannot effectively plug the defects. Therefore, this application proposes an impregnation vacuum welding repair device to solve the above problem. Utility Model Content

[0003] The main purpose of the utility model is to provide an infiltration vacuum welding device, which can effectively solve the problems in the background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an infiltration vacuum welding device, including a sealing cover, the sealing cover is provided with an open mouth, a casting is placed at the open mouth, the casting seals the inside of the sealing cover, and a joint pipe is provided on the sealing cover, and the joint pipe is connected to a negative pressure device through a hose.

[0005] Preferably, the opening of the sealing cover is arranged upward.

[0006] Preferably, a sealing gasket is fixed to the open end surface of the sealing cover.

[0007] Preferably, it further comprises a support frame, the support frame comprises a base, a bracket is fixed on the base, and the sealing cover is fixedly connected to the bracket.

[0008] Preferably, the sealing cover is a glass cover.

[0009] Preferably, the sealing cover is a spherical structure.

[0010] Compared with the traditional technology, the beneficial effect produced by the utility model is as follows: in the utility model, after the casting is placed in the open mouth to seal the sealing cover, the negative pressure device draws the air in the sealing cover to form a vacuum inside the sealing cover, so that a pressure difference is formed between the upper and lower surfaces of the casting. After the penetrant is poured into the surface of the casting, the penetrant can quickly penetrate into the tiny pinholes of the casting, thereby achieving effective welding repair of the tiny pinholes of the casting, greatly improving the welding repair quality of the casting, and further improving the yield rate of the casting.
