[0073] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0074] like Figures 1 to 7 As shown, the split-casing auxiliary assembly device of the embodiment of the present invention is used to assemble the split-casing 10 of an aircraft engine. The split-casing auxiliary assembly device comprises a main frame assembly 1 and a casing connection assembly 2 for connecting the split-casing 10, the casing connection assembly 2 is detachably connected to the top of the main frame assembly 1 and can move along the first direction X on the top of the main frame assembly 1, the casing connection assembly 2 has at least one adjustment mechanism 3, the adjustment mechanism 3 abuts against the main frame assembly 1 and is used to adjust the casing connection assembly 2 to move along the second direction Y, and the bottom of the main frame assembly 1 has at least one lifting mechanism 4, the lifting mechanism 4 abuts against the support surface and is used to adjust the casing connection assembly 2 to move along the height direction.

[0075] When the split-receive auxiliary assembly device is in use, the split-receive 10 is connected to the receiver connecting assembly 2, and the receiver connecting assembly 2 is installed and connected to the top of the main frame assembly 1 and can move along the first direction X on the top of the main frame assembly 1, thereby realizing the movement and adjustment of the split-receive 10 in the first direction X. The adjustment mechanism 3 is against the main frame assembly 1 and is used to adjust the movement of the receiver connecting assembly 2 along the second direction Y, thereby realizing the movement and adjustment of the split-receive 10 in the second direction Y. The lifting mechanism 4 can be used to adjust the movement of the receiver connecting assembly 2 in the height direction, thereby realizing the height adjustment of the split-receive 10. The split-receive auxiliary assembly device of this embodiment realizes position adjustment in the height direction, the first direction X and the second direction Y, and the adjustment is more precise, thereby ensuring the accuracy of the split-receive 10 during assembly, effectively solving the problem of poor accessibility during assembly of large split-receive 10, leaving sufficient space for personnel operation, facilitating operation, and greatly improving the safety and stability of the split-receive auxiliary assembly device. At the same time, the receiver connection assembly 2 is detachably connected to the top of the main frame assembly 1, and the receiver connection assembly 2 can be replaced and maintained. Subsequently, only the receiver connection assembly 2 needs to be changed to meet the needs of multiple models, thereby meeting the needs of multiple models without the need for customization of a single model. The time, manpower, and economic costs are greatly reduced, and the adaptability is good.

[0076] In this embodiment, the first direction X and the second direction Y are perpendicular to each other, the first direction X is longitudinal, and the second direction Y is transverse. Of course, in other embodiments, the first direction X and the second direction Y can be any direction without limitation.

[0077] The main frame assembly 1 includes a frame body 11 and a plurality of rollers 12, and the plurality of rollers 12 are connected to the bottom of the frame body 11. The casing connection assembly 2 is arranged on the frame body 11, and the split casing 10 extends into the frame body 11, and the center of gravity of the split casing 10 is located in the frame body 11. The movable main frame assembly 1 is designed, and the split casing auxiliary assembly device and the connected split casing 10 can be freely moved and positioned in the factory through the plurality of rollers 12, so that no crane assistance is required, saving costs. At the same time, the main frame assembly 1 can be quickly moved in each workstation through the plurality of rollers 12, which will drive the position adjustment of the split casing 10, and the adjustment is very convenient.

[0078] Compared with the traditional solution, when facing a large diameter receiver, since the support position is on the front load-bearing receiver, the large sliding distance of the receiver leads to a large force arm and a complex support structure. However, the split receiver auxiliary assembly device of this embodiment adopts that the center of gravity of the split receiver 10 is always located in the frame body 11, and the receiver connecting component 2 is arranged on the frame body 11 and moves and adjusts in the first direction X, so that the moving area ensures that the center of gravity of the split receiver 10 is located in the frame body 11, so that the overall structure of the split receiver auxiliary assembly device is simple, convenient to manufacture, and low cost.

[0079] The casing connection assembly 2 includes a connecting plate 21, and the split casing auxiliary assembly device also includes a plurality of slide rail assemblies 5, which are all arranged between the connecting plate 21 and the frame body 11. The slide rail assembly 5 includes a slider 52 and a slide rail 51 extending in the longitudinal direction. The slide rail 51 is connected to the top of the frame body 11, and the slider 52 is connected to the bottom of the connecting plate 21. The slider 52 is connected to the slide rail 51 and slides on the slide rail 51. The slider 52 slides on the slide rail 51, so that the connecting plate 21 and the split casing 10 can be moved and adjusted in the longitudinal direction, and the movement and adjustment are very convenient, and the structure is simple.

[0080] The connecting plate 21 has a first limiting hole 211 extending in the transverse direction, and the receiver connecting assembly 2 also includes a first limiting member 22, which passes through the first limiting hole 211 and is connected to the slider 52. One end of the adjusting mechanism 3 abuts against the slider 52, and the other end of the adjusting mechanism 3 is connected to the connecting plate 21 and can move in the transverse direction on the connecting plate 21. The first limiting member 22 moves in the transverse direction in the first limiting hole 211, so that the connecting plate 21 and the split receiver 10 as a whole move together in the predetermined transverse direction and do not move in other directions, effectively avoiding the displacement and misalignment of the connecting plate 21 and the split receiver 10 as a whole; at the same time, the first limiting hole 211 has a limiting effect, so that the distance of the first limiting member 22 moving in the transverse direction is the length of the first limiting hole 211, thereby limiting the transverse distance between the connecting plate 21 and the split receiver 10 as a whole, avoiding excessive movement of the connecting plate 21 and the split receiver 10 as a whole, and having higher stability.

[0081] In this embodiment, the adjustment mechanism 3 includes an adjustment screw, which is threadedly connected to the connecting plate 21. By rotating the adjustment screw and abutting against the slider 52, the length of the adjustment screw extending into the connecting plate 21 is adjusted to accurately adjust the distance between the connecting plate 21 and the split receiver 10 in the lateral direction, thereby achieving accurate lateral adjustment. There are two adjustment mechanisms 3, which are respectively located at the two ends of the connecting plate 21.

[0082] In this embodiment, the lifting mechanism 4 is threadedly connected to the bottom of the frame body 11, and the lifting mechanism 4 is rotated to achieve the lifting and lowering movement of the lifting mechanism 4 on the frame body 11. By rotating the lifting mechanism 4 and abutting against the support surface, the lifting mechanism 4 can be adjusted to move up and down, thereby accurately controlling the position of the main frame assembly 1 and the split casing 10 in the height direction, thereby achieving precise adjustment in the height direction. Among them, the number of lifting mechanisms 4 is four, and the four lifting mechanisms 4 are respectively located at the four corners of the frame body 11. Of course, in other embodiments, the lifting mechanism 4 can also adopt other structures to achieve lifting, and the specific structure may not be limited.

[0083] The bottom of the lifting mechanism 4 has a first support plate 41 extending outward. The first support plate 41 can increase the support area of ​​the lifting mechanism 4, so that the lifting mechanism 4 is more stably supported, has a simple structure and is low in cost.

[0084] The main frame assembly 1 also includes a plurality of lateral adjustment mechanisms 6, which are located below the adjustment mechanism 3. The plurality of lateral adjustment mechanisms 6 are connected to the frame body 11 and can move laterally on the frame body 11. The plurality of lateral adjustment mechanisms 6 are all against the assembly seat below the split receiver 10 and exert force on the assembly seat. The lateral movement of the lateral adjustment mechanism 6 will drive the assembly seat and the split receiver 10 to move and adjust in the lateral direction, thereby achieving precise lateral adjustment of the split receiver 10, ensuring the accuracy during assembly, and protecting components from damage.

[0085] In this embodiment, the top of the split receiver 10 is adjusted for lateral movement by the adjusting mechanism 3, and the assembly seat and the bottom of the split receiver 10 are adjusted for lateral movement by the lateral adjusting mechanism 6, which greatly improves the lateral adjustment accuracy of the split receiver auxiliary assembly device, ensures the accuracy during assembly, and protects components from damage.

[0086] The lateral adjustment mechanism 6 is threadedly connected to the bottom of the frame body 11, and the lateral adjustment mechanism 6 is rotated to achieve lateral movement of the lateral adjustment mechanism 6 on the frame body 11. By rotating the lateral adjustment mechanism 6 and abutting against the assembly seat, the lateral adjustment mechanism 6 can be adjusted to move laterally, thereby accurately controlling the lateral position of the split receiver 10, thereby achieving precise adjustment in the lateral direction. There are two lateral adjustment mechanisms 6, and the two lateral adjustment mechanisms 6 are respectively located at the two ends of the frame body 11 and respectively abut against the two ends of the assembly seat.

[0087] The lateral adjustment mechanism 6 has a second support plate 61 extending outwardly at one end thereof facing the split receiver 10. The second support plate 61 can increase the contact area between the lateral adjustment mechanism 6 and the assembly seat, making the movement and adjustment of the split receiver 10 more stable, simple in structure and low in cost.

[0088] The connecting plate 21 has a positioning groove 212 on one side facing the split receiver 10, and the positioning groove 212 has at least one first positioning portion 213 protruding outward. Both the positioning groove 212 and the first positioning portion 213 have a precise positioning function. The top of the split receiver 10 will extend into the positioning groove 212, and the first positioning portion 213 will extend into the through hole of the split receiver 10, thereby achieving precise positioning of the split receiver 10 and ensuring that the split receiver 10 is accurately fixed on the connecting plate 21. Among them, the first positioning portion 213 can be a positioning screw. By passing the positioning screw through the through hole of the split receiver 10 and connecting it to the positioning groove 212 of the connecting plate 21, the structure is simple and very convenient to use.

[0089] In this embodiment, the split receiver 10 is directly mounted and connected to the connecting plate 21 for fixed positioning. Subsequently, only the receiver connection assembly 2 is changed to meet the needs of multiple models, that is, the connection plate 21 is replaced to meet the needs of multiple models, and no single model needs to be customized. Of course, in other embodiments, the receiver connection assembly 2 may include an adapter plate, which is connected to the connecting plate 21, and the split receiver 10 is directly mounted and connected to the adapter plate. The adapter plate is set to connect to the corresponding split receiver 10, so there is no need to replace the connecting plate 21. Only the corresponding adapter plate is needed to meet the needs of multiple models, and no single model needs to be customized.

[0090] The receiver connection assembly 2 also includes a receiver clamping mechanism 23, the top of which is connected to the connection plate 21, and the bottom of which is connected to the lower mounting edge of the split receiver 10. The top of the split receiver 10 is connected and precisely positioned through the connection plate 21, and the bottom of the split receiver 10 is connected and precisely positioned through the receiver clamping mechanism 23, so that the split receiver 10 is precisely positioned and fixed, effectively avoiding the offset and dislocation of the split receiver 10 during the assembly process, thereby ensuring the accuracy of the split receiver 10 during assembly and greatly improving the safety and stability of the split receiver auxiliary assembly device.

[0091] The bottom of the receiver clamping mechanism 23 has at least one second positioning portion 231 protruding outward. The second positioning portion 231 has a precise positioning function. The second positioning portion 231 will pass through the through hole of the lower mounting edge of the split receiver 10, thereby achieving precise positioning of the split receiver 10 and ensuring that the split receiver 10 is accurately fixed on the receiver clamping mechanism 23. The second positioning portion 231 can be a positioning screw. By passing the positioning screw through the through hole of the lower mounting edge of the split receiver 10 and connecting it to the receiver clamping mechanism 23, the structure is simple and very convenient to use.

[0092] The split receiver auxiliary assembly device also includes a longitudinal adjustment mechanism 7, one end of which is connected to the receiver connection assembly 2, and the other end of which is connected to the main frame assembly 1 and can move longitudinally on the main frame assembly 1. The longitudinal adjustment mechanism 7 moves longitudinally on the main frame assembly 1, which will drive the receiver connection assembly 2 and the split receiver 10 to move and adjust in the longitudinal direction, thereby achieving precise longitudinal adjustment of the split receiver 10, ensuring the accuracy during assembly and protecting components from damage.

[0093] The longitudinal adjustment mechanism 7 includes a screw rod 71 and a screw rod connector 72. The screw rod connector 72 is connected to the casing connection assembly 2. One end of the screw rod 71 is connected to the screw rod connector 72. The other end of the screw rod 71 is threadedly connected to the main frame assembly 1. By rotating the screw rod 71, the screw rod 71 and the screw rod connector 72 are moved and adjusted in the longitudinal direction, thereby accurately controlling the longitudinal position of the split casing 10, thereby achieving precise adjustment in the longitudinal direction.

[0094] The receiver connection assembly 2 has at least one second stopper hole extending in the transverse direction, and the longitudinal adjustment mechanism 7 also includes at least one second stopper 73, which passes through the second stopper hole and is connected to the screw connection member 72. The second stopper 73 moves in the transverse direction in the second stopper hole, so that the connecting plate 21 and the split receiver 10 as a whole move together in the predetermined transverse direction without moving in other directions, effectively avoiding the displacement and misalignment of the connecting plate 21 and the split receiver 10 as a whole; at the same time, the second stopper hole has a limiting effect, so that the distance of the second stopper 73 moving in the transverse direction is the length of the second stopper hole, thereby limiting the transverse distance between the connecting plate 21 and the split receiver 10 as a whole, and having higher stability.
