TECHNICAL FIELD

[0001] The utility model belongs to titanium alloy cast vane technical field especially is related to a kind of X-ray detection tool for titanium alloy cast vane. BACKGROUND

[0002] Titanium alloy cast vane is the key component of engine, when X-ray detection is carried out to titanium alloy cast vane, titanium alloy cast vane is fixed on detection tool, when titanium alloy cast vane and tool are arranged in X-ray field and are irradiated, the radiation intensity of X-ray is influenced by internal defect of titanium alloy casting.The radiation intensity that is shot through titanium alloy casting has local change with the defect size, nature difference, forms the defect radiographic image, is recorded by X-ray film and is developed, or is observed in real time by fluorescent screen, or is detected by radiation counter instrument.The method of developing by radiographic film is commonly used method, that is, the X-ray photographic detection usually said, the defect image reflected by X-ray photography is intuitive, and defect shape, size, quantity, plane position and distribution range can be presented.Titanium alloy cast vane is fixed on the existing detection tool, titanium alloy cast vane and detection tool are in perpendicular state at top surface, when X-ray detection is carried out to titanium alloy cast vane, some special surfaces (such as blade body exhaust edge) of titanium alloy cast vane cannot be well detected, cannot guarantee that the angle of R ∠ of blade crown fish blade body and effective area area are better projected on film, and there is the problem of missed detection. SUMMARY

[0003] The utility model provides a kind of X-ray detection tool for titanium alloy cast vane including shallow pot shape tool and square frame tool, and the different detection parts of blade are assisted and fine-tuned, improve the flexibility of field operation, increase work efficiency, reduce the use of consumables.

[0004] To solve the above technical problems, the present application is realized by the following technical scheme: an X-ray detection tool for titanium alloy cast vane, comprising a shallow pot shape tool and a square frame tool.

[0005] The main body of the shallow pot shape tool is set as a shallow pot structure, and four groups of first insertion holes are arranged in a ring array inside the shallow pot structure. Each group of first insertion holes is parallelly arranged with eight first insertion holes. Each first insertion hole is perpendicularly arranged with the shallow pot structure. A first through hole is arranged at the center position of the shallow pot shape tool.

[0006] The main body of the square frame tool is set as a cuboid structure. The square frame tool is arranged with four groups of second insertion holes in a ring array. Each group of first insertion holes is linearly arranged with eight first insertion holes. A second through hole is arranged at the center position of the shallow pot shape tool.

[0007] The inner wall of the shallow pot-shaped fixture, the vertical wall of the square frame fixture, and the bottom are fixedly equipped with diffuser protection.

[0008] Preferably, the diameter of the shallow pot-shaped structure is set to 90-110 cm.

[0009] Preferably, lead plates are used for the scattering protection.

[0010] Preferably, the spacing between the first sockets in each group is 1-3 cm, and the spacing between the second sockets in each group is 1-3 cm.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] The shallow, pot-shaped curvature of the blade allows the exhaust edge angle of the titanium alloy cast blade to better conform to the film within the radiation field, especially at the R∠ point of the blade crown and body, ensuring better projection of the angle and effective area onto the film, achieving the goal of no missed inspections. The square-frame fixture performs comprehensive inspection of the titanium alloy cast blade, with its crown and tenon root meeting the projection angle of the radiation field. Both of these fixtures make efficient use of the space of the large film sheet, cutting and segmenting the film for specific local areas. They offer advantages such as high overall film utilization and the ability to inspect up to 32 blades at once, reducing film usage and saving time. Attached Figure Description
