Description

Technical Field

[0001] This invention relates to the field of engine drive shaft processing and forming technology, specifically to an automated processing and forming device for aircraft engine drive shafts. Background Technology

[0002] The engine driveshaft is one of the key components of an aircraft engine, responsible for transmitting the torque generated by the engine to the propeller, fan, or other drive components. The performance of the driveshaft directly affects the overall efficiency and reliability of the engine, as well as the aircraft's flight performance. With the continuous development of aviation technology, the requirements for aircraft performance are becoming increasingly stringent. At the same time, advanced non-ferrous metal materials, due to their unique advantages, are being used more and more widely in the aviation field, while the processing quality requirements for aircraft engine driveshafts are becoming increasingly demanding.

[0003] Citing the Chinese utility model patent with publication number "CN212761390U", the processing device body includes a protective cover, a motor shaft, a washing blade, a hydraulic device, a dust removal device, and a control motor. The top outer end of the processing device body is provided with a protective cover, the top middle of the protective cover is provided with a second sliding rail, the top of the second sliding rail is slidably connected to a slider, the top of the slider is provided with a hydraulic device, the bottom of the hydraulic device is connected to the washing blade via a connecting rod, the right end of the hydraulic device is connected to an electric push rod device via a push rod, the bottom right end of the processing device body is provided with a dust removal device, and the right end of the first sliding rail is slidably connected to a clamping and fixing block.

[0004] However, there are problems in the current production and processing of aircraft engine drive shafts.

[0018] This invention provides an automated machining and forming apparatus for aircraft engine drive shafts. It offers the following advantages:

[0019] 1. This automated machining and forming device for aircraft engine drive shafts, by setting a first arc-shaped support block, after the drive shaft is placed on the surface of the first arc-shaped support block, the fifth motor is started to drive the second slider to move in opposite directions, and a small roller is set inside the first arc-shaped support block to facilitate the adjustment of the drive shaft, avoid friction causing the drive shaft to shift and affect subsequent processing, thereby exposing the unprocessed surface of the drive shaft, making it easier to perform comprehensive processing on the drive shaft surface, solving the problem that the device can only process rotating shafts such as those with rectangular holes set on both sides of the engine drive shaft, thus getting rid of the dependence on the pre-set rectangular holes of the drive shaft, and enhancing the practicality of the device.

[0020] 2. This automated processing and forming device for aircraft engine drive shafts uses two sets of arc-shaped fixing blocks. An eighth motor, via its output shaft, moves the arc-shaped fixing blocks towards the surface of the drive shaft, thus restricting its movement and preventing loosening during rotation. Furthermore, a third connecting rod is included. As the eighth motor continuously moves the arc-shaped fixing blocks towards the drive shaft surface, the blocks slide inside the first slider, causing the second connecting rod to rotate. Finally, through linkage transmission, the third connecting rod further fixes the drive shaft surface. This makes the processing more stable and reliable, reducing scrap rates due to unstable fixing and further improving the device's processing efficiency.

[0021] 3. This automated machining and forming device for aircraft engine drive shafts, by setting a sixth connecting rod, drives the third slider to move in the direction of the sixth motor after the sixth motor is started, thereby fixing the rotating shaft with the sixth connecting rod and preventing displacement of the rotating shaft when sliding on the surface of the first arc-shaped support block. This ensures the normal machining of the remaining surfaces of the rotating shaft and indirectly improves the machining efficiency of the device.

[0022] 4. This automated processing and forming device for aircraft engine drive shafts, by setting a first arc-shaped rotating plate to mesh with a second gear, starts a seventh motor to drive the first arc-shaped rotating plate to rotate through gear meshing, thereby causing the drive shaft on the top of the second arc-shaped support block to slide into the drive shaft collection groove of the base. This reduces labor intensity, improves the working environment, and also helps to reduce operational errors caused by worker fatigue, greatly shortens the processing cycle of a single drive shaft, and improves the overall processing efficiency.

[0023] 5. This automated processing and forming device for aircraft engine drive shafts, by setting a second arc-shaped rotating plate, allows the drive shaft to fall on the support plate on top of the second arc-shaped rotating plate during unloading, which plays a buffering and protective role for the drive shaft, thereby avoiding damage to the drive shaft due to collision and resulting in product defects, thus improving the processing efficiency of the device.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0035] Example 1: Please refer to Figure 1-6 This invention provides a technical solution: an automated machining 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 drive mechanism 5 fixedly connected inside the base 1. Although it can achieve comprehensive machining of the drive shaft when the hole type is matched, it has a significant drawback. If the aircraft engine drive shaft design does not include such rectangular holes, or the hole type does not match the device, the machining device cannot be used, greatly limiting its versatility and applicability. Traditional machining devices that rely on pre-set rectangular holes for fixing can no longer meet the needs of modern aerospace manufacturing. Designing a completely new automated machining and forming device is an inevitable choice to improve the machining efficiency and quality of aircraft engine drive shafts. It can not only adapt to the machining of drive shafts with different design requirements and ensure the continuity of production, but also improve the overall performance and reliability of aero engines through stable fixing and efficient machining. The drive mechanism 5 includes a fifth motor 51. A second slider 52 is slidably connected inside the fifth motor 51 via its output shaft. A fixing mechanism 3 is fixedly connected to the top of the second slider 52. A third fixing block 6 is fixedly connected inside the base 1. A buffer mechanism 8 is rotatably connected to the surface of the third fixing block 6. During the unloading process of the aircraft engine drive shaft, the drive shaft components collide and generate significant impact forces due to gravity and mechanical inertia. This not only easily scratches the surface of the drive shaft, affecting its precision and performance, leading to a decline in product quality, but also accelerates the wear of the unloading mechanism components, increasing equipment maintenance costs and downtime for repairs. Simultaneously, the vibration generated by the impact interferes with subsequent processing, affecting the stability and efficiency of the entire production process. Therefore, setting up the buffer mechanism 8 is essential. It can protect the surface of the drive shaft, ensuring product quality; reduce wear on mechanical components, extending equipment lifespan and reducing maintenance costs; effectively suppress vibration, ensuring stable processing operation, and significantly improving the processing efficiency of the device. The surface of the third fixed block 6 is fixedly connected to a material feeding support mechanism 7. Currently, automated processing and forming devices for aircraft engine drive shafts mostly rely on manual material feeding, which suffers from low efficiency, easy damage to workpieces, and a messy work site, seriously affecting production progress and product quality, and making it difficult to meet the ever-increasing demands of aerospace manufacturing. Therefore, it is essential to set up a material feeding support mechanism 7, which can not only improve production efficiency and product quality and achieve seamless integration with automated equipment, but also optimize on-site management, reduce the labor intensity of workers, and ensure safe and orderly production.

[0036] Fixed mechanism 3 includes:

[0037] The first fixing block 34 is fixedly connected to the top of the second slider 52, and the surface of the first fixing block 34 is fixedly connected to the support mechanism 4.

[0038] The support mechanism 4 includes a second fixing block 42, which is fixedly connected to the surface of the first fixing block 34. A fourth motor 41 is fixedly connected to the bottom of the second fixing block 42. A first arc-shaped support block 43 is fixedly connected inside the fourth motor 41 through an output shaft. A small roller 44 is rotatably connected inside the first arc-shaped support block 43.

[0039] The fixing mechanism 3 also includes a third motor 31, which is fixedly connected to the surface of the first fixing block 34. The third motor 31 is fixedly connected to a first gear 32 through an output shaft. The first gear 32 is meshed with a turntable 33, and the turntable 33 is rotatably connected inside the first fixing block 34.

[0040] The first fixed block 34 is internally slidably connected to a first slider 36, the first slider 36 is internally slidably connected to a first connecting rod 38, one end of the first connecting rod 38 is fixedly connected to an arc-shaped fixed block 35, the other end of the first connecting rod 38 is fixedly connected to a toothed block 39, and the surface of the first connecting rod 38 is fixedly connected to a first spring 37.

[0041] A fourth fixing block 312 is fixedly connected to the surface of the first slider 36. A second connecting rod 310 is rotatably connected to the surface of the fourth fixing block 312, and the second connecting rod 310 is meshed with the toothed block 39. A third connecting rod 311 is rotatably connected inside the second connecting rod 310. A fourth connecting rod 313 is rotatably connected to the surface of the first slider 36, and the fourth connecting rod 313 is rotatably connected to the third connecting rod 311. An eighth motor 314 is fixedly connected inside the turntable 33, and the inside of the eighth motor 314 is slidably connected to the first slider 36 through an output shaft.

[0042] 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. A sliding support plate 23 is slidably connected inside the first motor 22 through its output shaft. The sliding support plate 23 is slidably connected inside the adjusting support beam 21. A second motor 25 is fixedly connected inside the sliding support plate 23. A cutter head fixing block 24 is slidably connected inside the second motor 25 through its output shaft. The cutter head fixing block 24 is slidably connected inside the sliding support plate 23.

[0043] In operation, the fifth motor 51 is first started. The start of the fifth motor 51 drives the two second sliders 52 to move in opposite directions via its output shaft, thereby causing the first fixed block 34 to move in the opposite direction as well. The drive shaft is then placed on top of the second arc-shaped support block 72 and adjusted to a suitable position. The fifth motor 51 is then started again, ultimately causing the first fixed blocks 34 to move towards each other, so that both ends of the drive shaft first pass through the axis of the turntable 33. The eighth motor 314 is then started. The start of the eighth motor 314 drives the first slider 36 to slide inside the turntable 33 via its output shaft. The sliding of the turntable 33 causes the two arc-shaped fixed blocks 35 to move towards the surface of the drive shaft, thus initially fixing the drive shaft and preventing it from loosening during rotation. Further control is applied to keep the eighth motor 314 running continuously. At this time, the arc-shaped fixed blocks 35 drive the first connecting rod 38 to slide inside the first slider 36, and cause the toothed block 39 to move away from the surface of the drive shaft. The direction of movement causes the tooth block 39 to drive the second connecting rod 310 to rotate. The rotation of the second connecting rod 310 causes the third connecting rod 311 to rotate on the surface of the second connecting rod 310. Under the restriction of the fourth connecting rod 313, one end of the third connecting rod 311 further fixes the surface of the transmission shaft, making the processing process more stable and reliable, reducing the scrap rate caused by unstable fixing, and thus further improving the processing efficiency of the device. Then, the first motor 22 is started. The start of the first motor 22 allows for easy adjustment of the height of the sliding support plate 23 through the output shaft. Then, the second motor 25 is started. The start of the second motor 25 allows for easy adjustment of the position of the cutter head fixing block 24 through the output shaft, so as to perform forming processing on the transmission shaft. At this time, the third motor 31 can be started. The start of the third motor 31 drives the first gear 32 to rotate through the output shaft. The rotation of the first gear 32 drives the turntable 33 to rotate, thereby driving the transmission shaft to rotate together, thus facilitating comprehensive forming processing on the transmission shaft.

[0044] After the surface forming of the drive shaft is completed, the eighth motor 314 is first started to make the arc-shaped fixing block 35 no longer fix the drive shaft. 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 towards the drive shaft through the output shaft, thus supporting the drive shaft. Then, the fifth motor 51 is started. The start of the fifth motor 51 finally drives the first fixing block 34 to adjust its position again, thereby exposing the unprocessed area on the drive shaft surface, which is convenient for comprehensive processing of the drive shaft surface. This solves the problem that the device can only process rotating shafts such as those with rectangular holes on both sides of the engine drive shaft, thus getting rid of the dependence on the pre-set rectangular holes of the drive shaft and enhancing the practicality of the device.

[0045] By setting the 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 towards each other. 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 causing the drive shaft to shift and affect subsequent processing. This exposes the unprocessed surface of the drive shaft, making it easier to fully process the drive shaft surface. This solves the problem that the device can only process rotating shafts such as those with rectangular holes set on both sides of the engine drive shaft, thus getting rid of the dependence on the pre-set rectangular holes of the drive shaft and enhancing the practicality of the device.

[0046] By setting two sets of arc-shaped fixing blocks 35, the eighth motor 314 is started and drives the arc-shaped fixing blocks 35 to move towards the surface of the transmission shaft through the output shaft, thereby restricting the movement of the transmission shaft and preventing the transmission shaft from becoming loose during rotation. Furthermore, a third connecting rod 311 is set. When the eighth motor 314 continuously drives the arc-shaped fixing blocks 35 to move towards the surface of the transmission shaft, the arc-shaped fixing blocks 35 slide inside the first slider 36, thereby driving the second connecting rod 310 to rotate. Finally, through the linkage transmission, the third connecting rod 311 further fixes the surface of the transmission shaft. This makes the processing process more stable and reliable, reduces the scrap rate caused by unstable fixing, and further improves the processing efficiency of the device.

[0047] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution:

[0048] The feeding support mechanism 7 includes a seventh motor 710, which is fixedly connected to the surface of the third fixed block 6. The seventh motor 710 is fixedly connected to a second gear 711 through an output shaft. The second gear 711 is meshed with the first arc-shaped rotating plate 71. The third fixed block 6 is fixedly connected to a limit block 79, and the first arc-shaped rotating plate 71 is slidably connected to the limit block 79.

[0049] 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 interior of the fifth connecting rod 73 is fixedly connected to the sixth motor 74, the interior 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.

[0050] The third slider 76 is internally slidably connected to the fourth slider 77, and 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 limit rod 75, and the limit rod 75 is slidably connected to the third slider 76.

[0051] 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. A third spring 84 is fixedly connected to the top of the second arc-shaped rotating plate 81, and a support plate 83 is fixedly connected to the top of the third spring 84. A second spring 82 is fixedly connected to the bottom of the second arc-shaped rotating plate 81, and the surface of the second spring 82 is fixedly connected to the third fixed block 6.

[0052] In use, the sixth motor 74 is started when the first arc-shaped support block 43 supports the drive shaft. The start of the sixth motor 74 drives the third slider 76 to move in 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 to the end of the third slider 76. The movement of the fourth slider 77 drives the sixth connecting rod 78 to rotate, thereby fixing the drive shaft with the sixth connecting rod 78. This prevents the rotating shaft from shifting when it slides on the surface of the first arc-shaped support block 43, thus ensuring the normal processing of the other surfaces of the rotating shaft and indirectly improving the processing efficiency of the device.

[0053] After all the surfaces of the transmission are machined, the fifth motor 51 is started, which ultimately drives the two first fixed blocks 34 to move in opposite directions, thereby freeing the transmission shaft from the partial fixed constraint. 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 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. This reduces labor intensity, improves the working environment, and also helps to reduce operational errors caused by worker fatigue. It greatly shortens the processing cycle of a single transmission shaft, improves the overall processing efficiency, and avoids product defects caused by damage to the transmission shaft due to collisions, thereby further improving the processing efficiency of the device.

[0054] By setting the sixth connecting rod 78, the sixth motor 74 is started and drives the third slider 76 to move in the direction of the sixth motor 74, thereby fixing the rotating shaft with the sixth connecting rod 78. This prevents the rotating shaft from shifting when it slides on the surface of the first arc-shaped support block 43, thus ensuring the normal processing of the other surfaces of the rotating shaft and indirectly improving the processing efficiency of the device.

[0055] By setting the first arc-shaped rotating plate 71 to mesh with the second gear 711, the seventh motor 710 is started and drives the first arc-shaped rotating plate 71 to rotate through gear meshing transmission, so that the transmission shaft on the top of the second arc-shaped support block 72 slides into the transmission shaft collection groove of the base 1, which reduces labor intensity, improves the working environment, and also helps to reduce operational errors caused by worker fatigue, greatly shortens the processing cycle of a single transmission shaft, and improves the overall processing efficiency.

[0056] By setting a second arc-shaped rotating plate 81, the drive shaft falls on the support plate 83 on top of the second arc-shaped rotating plate 81 when unloading, which plays a buffering and protective role for the drive shaft, thereby avoiding damage to the drive shaft due to collision and resulting in product defects, thus improving the processing efficiency of the device.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
