[0002] The drive shaft of an aircraft engine is a key component, responsible for transmitting the engine's torque to the aircraft's propeller, fan, or other drive components. The performance of the drive shaft directly impacts the engine's overall efficiency and reliability, as well as the aircraft's flight performance. With the continuous advancement of aviation technology, the requirements for aircraft performance are becoming increasingly stringent. At the same time, advanced non-ferrous metals are increasingly widely used in the aviation field due to their unique advantages. Simultaneously, the processing quality requirements for aircraft engine drive shafts are becoming increasingly demanding.

[0004] However, there are currently problems in the production and processing of aircraft engine drive shafts. The fixing units in the existing devices rely on the preset rectangular holes at both ends of the aircraft engine drive shaft.

In addition, the drive shaft is only fixed by the preset rectangular holes of the drive shaft. When the drive shaft needs to rotate at high speed during the processing, the fixation will be unstable.

A third connecting rod is further set. When the eighth motor continuously drives the arc-shaped fixing blocks to move toward the surface of the drive shaft, the arc-shaped fixing blocks slide inside the first slider, thereby driving the second connecting rod to rotate, and finally driving the third connecting rod to further fix the surface of the drive shaft through the connecting rod transmission action.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0024] Example 1: Please refer to Figure 1-6The present invention provides a technical solution: an automated processing and forming device for aircraft engine drive shafts, comprising a base 1, a cutting mechanism 2 fixedly connected to the surface of the base 1, and a driving mechanism 5 fixedly connected to the interior of the base 1. Although the drive shaft can be fully processed when the hole pattern is matched, there is a significant defect. Once there is no such rectangular hole in the design of the aircraft engine drive shaft, or the hole pattern does not match the device, the processing device cannot be used, which greatly limits its versatility and scope of application. Traditional processing devices that rely on preset rectangular holes for fixation can no longer meet the needs of the modern aviation manufacturing industry. Designing a new automated processing and forming device is an inevitable choice to improve the processing efficiency and quality of aircraft engine drive shafts. It can not only adapt to the processing of drive shafts with different design requirements and ensure the continuity of production, but also improve the overall performance and reliability of aircraft engines through stable fixation and efficient processing. The drive mechanism 5 includes a fifth motor 51. A second slider 52 is slidably connected to the interior of the fifth motor 51 via an output shaft. The top of the second slider 52 is fixedly connected to the fixing mechanism 3. A third fixing block 6 is fixedly connected to the interior of the base 1. The surface of the third fixing block 6 is rotatably connected to a buffer mechanism 8. During the blanking process of the aircraft engine drive shaft, due to gravity and mechanical inertia, the drive shaft components collide and generate a large impact force. This not only easily scratches the drive shaft surface, affecting its precision and performance, resulting in a decline in product quality, but also accelerates wear of the blanking mechanism components, increasing equipment maintenance costs and downtime for overhauls. Furthermore, the vibration generated by the impact can interfere with subsequent processing and affect the stability and efficiency of the entire production process. Therefore, the provision of a buffer mechanism 8 is essential. It can protect the drive shaft surface and ensure product quality; reduce wear of mechanical components, extend the service life of the equipment, and reduce maintenance costs; effectively suppress vibration, ensure stable processing, and significantly improve the processing efficiency of the device. The surface of the third fixed block 6 is fixedly connected to a blanking support mechanism 7. Currently, most automated processing and forming devices for aircraft engine drive shafts rely on manual blanking, which has problems such as low efficiency, easy damage to the workpiece, and clutter on the site. This seriously affects production progress and product quality, making it difficult to meet the growing demand for aviation manufacturing. Therefore, the installation of a blanking support mechanism 7 is very necessary. It not only improves production efficiency and product quality, achieves seamless integration with automated equipment, but also optimizes on-site management, reduces worker labor intensity, and ensures safe and orderly production. The fixing mechanism 3 comprises: A first fixed block 34, the first fixed block 34 is fixedly connected to the top of the second slider 52, and the surface of the first fixed block 34 is fixedly connected to the support mechanism 4; The support mechanism 4 includes a second fixed block 42, which is fixedly connected to the surface of the first fixed block 34. The bottom of the second fixed block 42 is fixedly connected to the fourth motor 41. The interior of the fourth motor 41 is fixedly connected to the first arc-shaped support block 43 through the output shaft. The interior of the first arc-shaped support block 43 is rotatably connected to a small roller 44.

[0025] The fixing mechanism 3 also includes a third motor 31, which is fixedly connected to the surface of the first fixed block 34. The interior of the third motor 31 is fixedly connected to the first gear 32 through an output shaft. The first gear 32 is meshed and connected to the turntable 33, and the turntable 33 is rotatably connected to the interior of the first fixed block 34.

[0026] The first fixed block 34 is internally slidably connected to the first slider 36, and the first slider 36 is internally slidably connected to the first connecting rod 38. One end of the first connecting rod 38 is fixedly connected to the arc-shaped fixed block 35, and the other end of the first connecting rod 38 is fixedly connected to the tooth block 39. The surface of the first connecting rod 38 is fixedly connected to the first spring 37.

[0027] The surface of the first slider 36 is fixedly connected to the fourth fixed block 312, the surface of the fourth fixed block 312 is rotatably connected to the second connecting rod 310, and the second connecting rod 310 is engaged with the tooth block 39, the interior of the second connecting rod 310 is rotatably connected to the third connecting rod 311, the surface of the first slider 36 is rotatably connected to the fourth connecting rod 313, and the fourth connecting rod 313 is rotatably connected to the third connecting rod 311, the interior of the turntable 33 is fixedly connected to the eighth motor 314, and the interior of the eighth motor 314 is slidably connected to the first slider 36 through the output shaft.

[0028] The cutting mechanism 2 includes an adjusting support beam 21, which is fixedly connected to the surface of the base 1. A first motor 22 is fixedly connected to the top of the adjusting support beam 21. The interior of the first motor 22 is slidably connected to a sliding support plate 23 through an output shaft, and the sliding support plate 23 is slidably connected to the interior of the adjusting support beam 21. A second motor 25 is fixedly connected to the interior of the sliding support plate 23. The interior of the second motor 25 is slidably connected to a cutter head fixing block 24 through an output shaft, and the cutter head fixing block 24 is slidably connected to the interior of the sliding support plate 23.

[0029] When in use, first start the fifth motor 51. The start of the fifth motor 51 drives the two second sliders 52 to move in opposite directions through the output shaft, thereby driving the first fixed block 34 to move in opposite directions together, and then the transmission shaft is placed on the top of the second arc-shaped support block 72 and adjusted to a suitable position. Then, the fifth motor 51 is started again, and finally the first fixed block 34 is driven to move toward each other, so that the two ends of the transmission shaft first penetrate the axis of the turntable 33. Then, the eighth motor 314 is started. The start of the eighth motor 314 drives the first slider 36 to slide inside the turntable 33 through the output shaft. The sliding of the turntable 33 drives the two arc-shaped fixed blocks 35 to move toward the surface of the transmission shaft, so that the arc-shaped fixed block 35 initially fixes the transmission shaft, avoiding the loosening of the transmission shaft during rotation. The eighth motor 314 is further controlled to continue to start. At this time, the arc-shaped fixed block 35 drives the first connecting rod 38 to slide inside the first slider 36, and causes the gear block 39 to move away from the surface of the transmission shaft. The third motor 31 can be started at this time, and the start of the third motor 31 drives the first gear 32 to rotate through the output shaft, and the rotation of the first gear 32 drives the turntable 33 to rotate, thereby driving the transmission shaft to rotate together, thereby facilitating comprehensive forming processing of the transmission shaft.

[0030] After the surface forming processing of the transmission shaft is completed, the eighth motor 314 is first controlled to start, so that the arc-shaped fixed block 35 no longer fixes the transmission shaft, and then the fourth motor 41 is started at the same time. The start of the fourth motor 41 drives the first arc-shaped support block 43 to move toward the direction of the transmission shaft through the output shaft, thereby supporting the transmission shaft. Then the fifth motor 51 is started. The start of the fifth motor 51 finally drives the first fixed block 34 to adjust its position again, thereby exposing the position of the transmission shaft surface for processing, which is convenient for comprehensive processing of the transmission shaft surface, and solves the problem that the device can only process rotating shafts such as rectangular holes provided on both sides of the engine transmission shaft, thereby getting rid of the dependence on the preset rectangular holes of the transmission shaft and enhancing the practicality of the device.

[0031] By setting a first arc-shaped support block 43, after the drive shaft is placed on the surface of the first arc-shaped support block 43, the fifth motor 51 is started to drive the second slider 52 to move toward each other, and a small roller 44 is set inside the first arc-shaped support block 43 to facilitate the adjustment of the drive shaft and avoid friction-induced displacement of the drive shaft affecting subsequent processing, thereby exposing the unprocessed surface of the drive shaft, facilitating comprehensive processing of the drive shaft surface, and solving the problem that the device can only process rotating shafts such as rectangular holes provided on both sides of the engine drive shaft, thereby getting rid of the dependence on the preset rectangular holes of the drive shaft and enhancing the practicality of the device.

[0032] By setting two groups of arc-shaped fixing blocks 35, starting the eighth motor 314 drives the arc-shaped fixing block 35 to move toward the surface direction of the transmission shaft through the output shaft, thereby limiting the movement of the transmission shaft and avoiding the loosening of the transmission shaft during rotation. A third connecting rod 311 is further set. When the eighth motor 314 continuously drives the arc-shaped fixing block 35 to move toward the surface direction of the transmission shaft, the arc-shaped fixing block 35 slides inside the first slider 36, thereby driving the second connecting rod 310 to rotate, and finally driving the third connecting rod 311 to further fix the surface of the transmission shaft through the connecting rod transmission action, which makes the processing process more stable and reliable, reduces the scrap rate caused by unstable fixation, and further improves the processing efficiency of the device.

[0033] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The unloading support mechanism 7 includes a seventh motor 710, which is fixedly connected to the surface of the third fixed block 6. The interior of the seventh motor 710 is fixedly connected to the second gear 711 through the output shaft. The second gear 711 is meshed with the first arc-shaped rotating plate 71. The interior of the third fixed block 6 is fixedly connected to the limit block 79, and the first arc-shaped rotating plate 71 is slidingly connected to the limit block 79.

[0034] The top of the first arc-shaped rotating plate 71 is fixedly connected to the fifth connecting rod 73, the top of the fifth connecting rod 73 is fixedly connected to the second arc-shaped support block 72, the inside of the fifth connecting rod 73 is fixedly connected to the sixth motor 74, the inside of the sixth motor 74 is slidably connected to the third slider 76 through the output shaft, and the third slider 76 is slidably connected to the fifth connecting rod 73.

[0035] The third slider 76 is internally slidably connected to the fourth slider 77, the surface of the fourth slider 77 is rotatably connected to the sixth connecting rod 78, the sixth connecting rod 78 is rotatably connected to the second arc-shaped support block 72, the fifth connecting rod 73 is internally fixedly connected to the limiting rod 75, and the limiting rod 75 is slidably connected to the third slider 76.

[0036] The buffer mechanism 8 includes a second arc-shaped rotating plate 81, which is rotatably connected to the surface of the third fixed block 6. The top of the second arc-shaped rotating plate 81 is fixedly connected to a third spring 84, and the top of the third spring 84 is fixedly connected to a support plate 83. The bottom of the second arc-shaped rotating plate 81 is fixedly connected to a second spring 82, and the surface of the second spring 82 is fixedly connected to the third fixed block 6.

[0037] When in use, the sixth motor 74 is started when the first arc-shaped support block 43 supports the transmission shaft. The start of the sixth motor 74 drives the third slider 76 to move toward the direction of the sixth motor 74 through the output shaft. The movement of the third slider 76 drives the fourth slider 77 to move toward the end of the third slider 76. The movement of the fourth slider 77 drives the sixth connecting rod 78 to rotate, so that the sixth connecting rod 78 fixes the transmission shaft, avoiding displacement of the rotating shaft when sliding on the surface of the first arc-shaped support block 43, thereby ensuring the normal processing of the remaining surfaces of the rotating shaft, and indirectly improving the processing efficiency of the device.

[0038] After all the processing of the transmission surface is completed, the fifth motor 51 is started to finally drive the two first fixed blocks 34 to move in the opposite direction, thereby freeing the transmission shaft from the fixed restriction. Then, the seventh motor 710 is started. The start of the seventh motor 710 drives the second gear 711 to rotate through the output shaft. The rotation of the second gear 711 drives the first arc-shaped rotating plate 71 to rotate clockwise. Then, the sixth motor 74 is controlled to be started. The start of the sixth motor 74 drives the third slider 76 to move away from the sixth motor 74 through the output shaft. The movement of the third slider 76 drives the fourth slider 77 to move in the direction of the fifth connecting rod 73, thereby freeing the sixth connecting rod 78 from the surface of the transmission shaft. The transmission shaft slides from the arc surface of the second arc-shaped support block 72 to the surface of the support plate 83, and finally slides through the surface of the support plate 83 into the collection groove of the base 1, which reduces labor intensity and improves the working environment. It also helps to reduce operational errors caused by worker fatigue, greatly shortens the processing cycle of a single transmission shaft, improves overall processing efficiency, and avoids damage to the transmission shaft due to collision, thereby preventing product defects, thereby further improving the processing efficiency of the device.

[0039] By setting the sixth connecting rod 78, after starting the sixth motor 74, the third slider 76 is driven to move in the direction of the sixth motor 74, so that the sixth connecting rod 78 fixes the rotating shaft, avoiding displacement of the rotating shaft when sliding on the surface of the first arc-shaped support block 43, thereby ensuring normal processing of the remaining surfaces of the rotating shaft, and indirectly improving the processing efficiency of the device.

[0040] By setting the first arc-shaped rotating plate 71 to engage with the second gear 711, starting the seventh motor 710 to drive the first arc-shaped rotating plate 71 to rotate through the gear meshing transmission, so that the transmission shaft on the top of the second arc-shaped support block 72 slides into the transmission shaft collecting groove of the base 1, reducing labor intensity and improving the working environment. At the same time, it also helps to reduce operational errors caused by worker fatigue, greatly shortens the processing cycle of a single transmission shaft, and improves overall processing efficiency.

[0041] By setting the second arc-shaped rotating plate 81, the transmission shaft falls on the support plate 83 on the top of the second arc-shaped rotating plate 81 during unloading, which plays a buffering and protective role for the transmission shaft, thereby avoiding damage to the transmission shaft due to collision and causing product defects, thereby improving the processing efficiency of the device.
