Description

Technical Field

[0001] This utility model relates to the field of aero-engine technology, specifically to tooling for machining the outer casing. Background Technology

[0002] The outer casing of a small turbojet engine is one of the engine's main load-bearing and protective components, and its strength and rigidity are subject to very strict requirements. The outer casing isolates the external environment from internal components such as the compressor, combustion chamber, and rotor, ensuring the engine's operational stability.

[0003] The outer casing may deform during processing, affecting the efficiency of subsequent processing. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a tooling for machining the outer casing.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An outer casing machining fixture includes a fixed frame, a fixing component on the fixed frame, an adjusting component on the fixed frame, and a limiting component on the adjusting component. The fixing component includes an inner circular abutment plate and a fixing plate. The inner circular abutment plate is mounted on the fixed frame, and the fixing plate is mounted on the fixed frame. A rotating threaded rod is movably mounted on the fixing plate, and a transmission block is movably mounted on the rotating threaded rod. A guide rod is provided on the fixed frame, and a slider is movably mounted on the guide rod. A connecting rod is movably mounted on the slider and is movably connected to the transmission block. A buffer component is provided on the slider.

[0007] As a preferred embodiment of this utility model, the fixing frame is provided with reinforcing ribs.

[0008] As a preferred embodiment of the present invention, the buffer assembly includes a support frame, a sliding plate movably mounted on the support frame, a spring mounted on the sliding plate and connected to the support frame, and a stop block mounted on the sliding plate.

[0009] As a preferred embodiment of this invention, the sliding plate is adapted to the support frame.

[0010] As a preferred embodiment of this utility model, the adjusting assembly includes a connecting frame, a rotating shaft movably mounted on the connecting frame, a rotating plate mounted on the rotating shaft, a first gear mounted at the end of the rotating shaft away from the rotating plate, a double-ended threaded rod movably mounted on the connecting frame, a second gear mounted on the double-ended threaded rod and meshing with the first gear, a fixed rod mounted on the connecting frame, a first movable frame movably mounted on the double-ended threaded rod and movably connected to the fixed rod, a first clamping frame mounted on the first movable frame, a second movable frame movably mounted on the double-ended threaded rod and movably connected to the fixed rod, and a second clamping frame mounted on the second movable frame.

[0011] As a preferred embodiment of this invention, the rotating plate is provided with anti-slip texture.

[0012] As a preferred embodiment of the present invention, the limiting component includes a limiting hole and a pin. The limiting hole is disposed on the connecting frame, and the pin is movably disposed on the rotating plate and abuts against the limiting hole.

[0013] As a preferred embodiment of this utility model, the limiting hole is provided in a plurality of manners.

[0014] The beneficial effects of this utility model are as follows: As a machining fixture for the outer casing, this utility model, at the level of inner circle fixing, has an inner circle abutment plate that penetrates deep into the outer casing to form a basic support. This, along with the linkage of core components such as the threaded rod, transmission block, connecting rod, and slider, drives the abutment block to precisely abut against the inner wall of the outer casing. The spring buffer device configured within ensures both the rigidity of the support force and the flexibility to prevent damage to the outer casing surface, achieving a stable support effect that combines rigidity and flexibility. For fixing the outer wall of the outer casing, the linkage between the rotating plate and the rotating shaft, along with the efficient drive of the precision gear transmission and the double-ended threaded rod, causes the first and second clamping frames to move symmetrically and synchronously towards each other, forming a ring-shaped clamping force. This dual-directional, coordinated fixing mechanism eliminates the potential for deformation of the outer casing due to uneven force during machining, significantly improving the reliability of the fixing structure and the stability of the machining process, thus laying a solid foundation for high-precision machining requirements.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] The following is combined Figure 1-3This invention describes a specific embodiment of an outer casing machining fixture, comprising a fixed frame 1, a fixing component on the fixed frame 1, an adjusting component on the fixed frame 1, and a limiting component on the adjusting component. The fixing component includes an inner circular abutment plate 2 and a fixing plate 3. The inner circular abutment plate 2 is mounted on the fixed frame 1, and the fixing plate 3 is mounted on the fixed frame 1. A rotating threaded rod 4 is movably mounted on the fixing plate 3, and a transmission block 5 is movably mounted on the rotating threaded rod 4. A guide rod 9 is provided on the fixed frame 1, and a slider 6 is movably mounted on the guide rod 9. A connecting rod 7 is provided and is movably connected to the transmission block 5. A buffer assembly is provided on the slider 6. A pair of sliders 6 and connecting rods 7 are provided. A pair of connecting rods 7 are movably connected to a pair of sliders 6 respectively. A pair of buffer assemblies are provided and are symmetrically arranged. When it is necessary to fix the inner circle of the outer casing, the inner circle abutment plate 2 is placed into the outer casing so that the inner circle abutment plate 2 supports the inner circle of the outer casing. Rotating the threaded rod 4 allows it to rotate on the fixed plate 3. The transmission block 5 moves under the action of the rotating threaded rod 4. Rotating the threaded rod 4 can drive the connecting rod 7 to move, which in turn can drive a pair of sliders 6 to slide on the guide rod 9.

[0023] Advantageously, the fixing frame 1 is provided with reinforcing ribs, which increases the stability of the fixing frame 1.

[0024] Advantageously, the buffer assembly includes a support frame 8, on which a sliding plate 10 is movably mounted. A spring 11 is mounted on the sliding plate 10 and connected to the support frame 8. A stop block 12 is mounted on the sliding plate 10. The slider 6 can drive the support frame 8 to move. The stop block 12 moves with the support frame 8 and abuts against the inner wall of the outer casing. The sliding plate 10 slides on the support frame 8, the spring 11 provides buffering, and the stop block 12 can better support the outer casing.

[0025] Advantageously, the sliding plate 10 is adapted to the support frame 8, and the adapted sliding plate 10 slides stably on the support frame 8.

[0026] Advantageously, the adjusting assembly includes a connecting frame 13, on which a rotating shaft 14 is movably mounted, and a rotating plate 15 is mounted on the rotating shaft 14. A first gear 18 is provided at the end of the rotating shaft 14 away from the rotating plate 15. A double-ended threaded rod 19 is movably mounted on the connecting frame 13, and a second gear 20 is provided on the double-ended threaded rod 19, meshing with the first gear 18. A fixed rod 21 is provided on the connecting frame 13. A first movable frame 22 is movably mounted on the double-ended threaded rod 19 and movably connected to the fixed rod 21. A first clamping frame 23 is provided on the first movable frame 22. A second movable frame 24 is movably mounted on the double-ended threaded rod 19. The second movable frame 24 is movably connected to the fixed rod 21. The second movable frame 24 is provided with a second clamping frame 25. When it is necessary to clamp the outer wall of the outer casing, the rotating plate 15 is rotated. The rotating plate 15 drives the rotating shaft 14 to rotate on the connecting frame 13. At this time, the first gear 18 rotates with the rotating shaft 14. The second gear 20 drives the double-headed threaded rod 19 to rotate under the action of the first gear 18. The first movable frame 22 and the second movable frame 24 approach each other under the action of the double-headed threaded rod 19. The first clamping frame 23 and the second clamping frame 25 approach each other under the action of the first movable frame 22 and the second movable frame 24 to contact the outer wall of the outer casing and clamp and fix it. The inner round abutment plate 2 is used to fix the outer casing.

[0027] Advantageously, the rotating plate 15 is provided with anti-slip texture, which makes it easier for the operator to rotate the rotating plate 15.

[0028] Advantageously, the limiting component includes a limiting hole 17 and a pin 16. The limiting hole 17 is provided on the connecting frame 13, and the pin 16 is movably provided on the rotating plate 15 and abuts against the limiting hole 17. When the first clamping frame 23 and the second clamping frame 25 abut against the outer wall of the outer casing, the pin 16 passes through the side wall of the rotating plate 15 and enters the pin 16 on the connecting frame 13 to limit the first clamping frame 23 and the second clamping frame 25.

[0029] Advantageously, the limiting holes 17 are provided in a plurality of manner, which facilitates the fixing of the rotating plate 15 at different positions by cooperating with the pin 16.

[0030] Working principle of this utility model:

[0031] First, when fixing the inner circle of the outer casing, the inner circle abutment plate 2 is placed inside the outer casing to support the inner circle of the outer casing. The threaded rod 4 is rotated, allowing it to rotate on the fixed plate 3. The transmission block 5 moves under the action of the threaded rod 4, which in turn moves the connecting rod 7, causing a pair of sliders 6 to slide on the guide rod 9. The sliders 6 move the support frame 8, and the abutment block 12 follows the support frame 8 to abut against the inner wall of the outer casing. The sliding plate 10 slides on the support frame 8, and the spring 11 provides cushioning. The abutment block 12 provides better support for the outer casing. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) When clamped on the side wall, the rotating plate 15 is rotated, and the rotating plate 15 drives the rotating shaft 14 to rotate on the connecting frame 13. At this time, the first gear 18 rotates with the rotating shaft 14, and the second gear 20 drives the double-headed threaded rod 19 to rotate under the action of the first gear 18. The first moving frame 22 and the second moving frame 24 approach each other under the action of the double-headed threaded rod 19. The first clamping frame 23 and the second clamping frame 25 approach each other under the action of the first moving frame 22 and the second moving frame 24 to contact the outer wall of the outer casing and clamp and fix it. The inner round abutment plate 2 is used to fix the outer casing to prevent deformation during the processing of the outer casing.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., 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 communication between 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.

[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
