Description

Technical Field

[0001] This utility model discloses a tooling structure, belonging to the field of casing deformation correction technology, specifically relating to a tooling for welding heat treatment of casing deformation correction. Background Technology

[0002] The aircraft intake casing is one of the most important components of an aero-engine. It serves as the base of the entire engine and is a major load-bearing component. Its complex structure varies depending on the engine and its location. While the function of the casing components determines its shape, they are fundamentally components consisting of a cylindrical or conical shell and support plates. Due to the high design difficulty and long development cycle of casing components, its design constitutes a significant portion of the overall engine design. Therefore, improving the design efficiency of the casing is crucial for the overall design of the compressor engine.

[0003] During production and later use, engine casings may develop deformation cracks. These cracks can lead to a decline in engine performance, insufficient air intake, reduced power output, and sluggish acceleration. They also significantly increase fuel consumption and economic burden. Therefore, deformation correction welding heat treatment is required for the engine casing. However, traditional deformation correction welding heat treatment technology involves directly welding the engine casing. This welding method cannot guarantee the stability of the weld. Furthermore, since the engine casing is circular, it is impossible to guarantee that the welded engine casing will return to its original position. Utility Model Content

[0004] Purpose of the utility model: To provide a welding heat treatment fixture for correcting deformation of a casing, thereby solving the aforementioned problems.

[0005] Technical solution: A welding heat treatment fixture for casing deformation correction, comprising: a base, an outer limiting ring, an inner limiting ring, a screw top seat, a double-rotating screw, and a top block;

[0006] In a further embodiment, the base is positioned at the bottom, the casing is mounted on the base via a clamping mechanism, the outer limiting ring is fixedly mounted on the outer ring of the casing, the inner limiting ring is fixedly mounted on the inner ring of the casing, the screw top seat is mounted inside the casing via the double-rotating screw, and the top block is fixedly mounted on the base via a clamping mechanism.

[0007] In a further embodiment, the clamping mechanism includes clamping bolts and washers.

[0008] In a further embodiment, the top block is mounted on the base and restricts the position of the casing on the base.

[0009] In a further embodiment, the dual-screw is provided with several screws, which are screwed onto the screw top seat in a circumferential array at equal intervals. The end of the screw top seat is provided with a support block, which contacts the inner wall of the casing.

[0010] Beneficial effects: This utility model is a fixing fixture for welding heat treatment of box-shaped deformation correction. The base, outer limiting ring and inner limiting ring press the box down. At the same time, the screw top seat and double screw ensure the circumference of the box and prevent deformation during welding. The top block is set to ensure that the box will not move during welding and ensure the stability of welding. Thus, this utility model can greatly improve welding efficiency and stability.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] A welding heat treatment fixture for casing deformation correction includes: a base 7, an outer limiting ring 4, an inner limiting ring 3, a screw top seat 2, a double-rotating screw 1, a top block 5, and a clamping mechanism 6.

[0017] In one embodiment, such as Figure 1 As shown, the base 7 is located at the bottom, the casing 8 is mounted on the base 7 through the clamping mechanism 6, the outer limiting ring 4 is fixedly mounted on the outer ring of the casing 8, the inner limiting ring 3 is fixedly mounted on the inner ring of the casing 8, the screw top seat 2 is mounted inside the casing 8 through the double-rotating screw 1, and the top block 5 is fixedly mounted on the base 7 through the clamping mechanism 6.

[0018] In one embodiment, such as Figure 1 As shown, the clamping mechanism includes clamping bolts and washers.

[0019] In one embodiment, such as Figure 1 As shown, the top block 5 is mounted on the base 7 and restricts the position of the casing 8 on the base 7.

[0020] In one embodiment, such as Figure 1 As shown, the double-screw 1 has several screws that are screwed onto the screw top seat 2 in a circumferential array at equal intervals. The end of the screw top seat 2 is provided with a support block, which contacts the inner wall of the casing 8.

[0021] Working principle: When this utility model is in operation, the casing 8 is first placed on the base 7 and fixed to the base 7 by the top block 5 to limit the bottom position of the casing 8. At the same time, the casing 8 is fixed to the base 7 by the clamping mechanism 6. Meanwhile, the inner ring of the casing 8 is fixed by the screw top seat 2 and the double screw 1 to prevent deformation during welding, thereby ensuring the stability of welding. Finally, the outer limiting ring 4 is fixedly installed on the outer ring of the casing 8, and the inner limiting ring 3 is fixedly installed on the inner ring of the casing 8, thereby completing the fixing and welding work.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
