[0025] like Figure 1 As shown, combined with Figure 2-9 As shown, the aircraft engine assembly platform of the present invention includes an AGV, wherein a first vertical frame 1 and a second vertical frame 22 are arranged opposite to each other on the body 3 of the AGV, a first sliding seat 2 is provided on the first vertical frame 1 for sliding along the vertical direction, the first sliding seat 2 is connected to a first driving device, the first driving device can drive the first sliding seat 2 to slide along the first vertical frame 1, the first sliding seat 2 is connected to one side of the first turntable 33 through a first slewing bearing 9, a first upper support plate 32 and a first lower support plate 10 are fixed on the other side of the first turntable 33, a first C-shaped ring 13 is slidably provided between the first upper support plate 32 and the first lower support plate 10, a second sliding seat 20 is provided on the second vertical frame 22 for sliding along the vertical direction, the second sliding seat 20 is connected to a second driving device, the second driving device can drive the second sliding seat 20 to slide along the second vertical frame 22, the second sliding seat 20 is connected to a second slewing bearing 19 It is connected to one side of the second turntable 23, and a second upper support plate 25 and a second lower support plate 18 are fixed on the other side of the second turntable 23, and a second C-shaped ring 14 is slidably provided between the second upper support plate 25 and the second lower support plate 18, and the first C-shaped ring 13 and the second C-shaped ring 14 form a circular closed ring for clamping the aircraft engine 29 (in actual use, the first C-shaped ring 13 and the second C-shaped ring 14 can be fixed by fasteners such as bolts to form a stable circular closed ring), and the first C-shaped ring 13 and the second C-shaped ring 14 are both provided with a clamping member 15 for clamping the aircraft engine 29, and the circular closed ring can rotate around its own axis under the drive of the third driving device. When the circular closed ring rotates around its own axis, the first C-shaped ring 13 slides relative to the first upper support plate 32 and the first lower support plate 10, and the second C-shaped ring 14 slides relative to the second upper support plate 25 and the second lower support plate 18.
[0026] When the aircraft engine assembly platform of the present invention is in use, the entire assembly platform can first be moved to a suitable position by an AGV. Then, the aircraft engine 29 is clamped in the circular closed loop formed by the first C-shaped ring 13 and the second C-shaped ring 14 by the clamping member 15.

As can be seen, since the present invention clamps the aircraft engine 29 by the relatively arranged first and second C-shaped rings 13 and 14, it is safer. Moreover, since the present invention uses the AGV as the support base, it can be easily moved.
[0027] like Figure 3 As shown, the aircraft engine assembly platform of the present invention, wherein the first vertical frame 1 is fixedly provided with a first slide rail 46 arranged in the vertical direction, the first sliding seat 2 is slidably installed on the first slide rail 46 through the first slider 41, the first driving device includes a first motor 4, a first reducer 42 and a first lifting screw 47, the first lifting screw 47 is rotatably installed on the first vertical frame 1 along the vertical direction, the first motor 4 and the first reducer 42 are arranged on the first vertical frame 1, the output shaft of the first motor 4 is connected to the input shaft of the first reducer 42, the output shaft of the first reducer 42 is connected to the lower end of the first lifting screw 47, and the first sliding seat 2 is threadedly connected to the first lifting screw 47.
[0028] The first vertical frame 1 includes a first top plate 37 and a first bottom plate 40, and a first vertical side plate 38 fixedly connected between the first top plate 37 and the first bottom plate 40. A first support plate 39 is provided between the first top plate 37 and the first bottom plate 40, and the first support plate 39 is fixedly connected to the first vertical side plate 38. The first slide rail 46 is fixedly mounted on the first vertical side plate 38 in the vertical direction. The upper and lower ends of the first lifting screw 47 are rotatably mounted on the first top plate 37 and the first support plate 39 respectively via bearings. The first motor 4 and the first reducer 42 are fixedly mounted on the lower surface of the first support plate 39. Of course, the first motor 4 and the first reducer 42 can also be fixedly mounted on the first bottom plate 40. A first nut is fixedly mounted inside the first sliding seat 2, and the first sliding seat 2 is threadedly connected to the first lifting screw 47 via the first nut.
[0029] When the first motor 4 drives the first lifting screw 47 to rotate through the first reducer 42, since the first sliding seat 2 is slidably mounted on the first slide rail 46 through the first slider 41, the first sliding seat 2 will not rotate with the first lifting screw 47, but will only slide up and down along the first slide rail 46.
[0030] like Figure 4 As shown, the aircraft engine assembly platform of the present invention is fixedly provided with a second slide rail 51 arranged in the vertical direction on the second vertical frame 22, the second sliding seat 20 is slidably installed on the second slide rail 51 through the second slider 49, the second driving device includes a second motor 8, a second reducer 48 and a second lifting screw 50, the second lifting screw 50 is rotatably installed on the second vertical frame 22 in the vertical direction, the second motor 8 and the second reducer 48 are provided on the second vertical frame 22, the output shaft of the second motor 8 is connected to the input shaft of the second reducer 48, the output shaft of the second reducer 48 is connected to the lower end of the second lifting screw 50, and the second sliding seat 20 is threadedly connected to the second lifting screw 50.
[0031] The second vertical frame 22 has the same structure as the first vertical frame 1. The second slide rail 51, second lifting screw 50, second motor 8, and second reducer 48 are mounted on the second vertical frame 22 in the same manner as the first slide rail 46, first lifting screw 47, first motor 4, and first reducer 42 are mounted on the first vertical frame 1. The second sliding seat 20 is also threadedly connected to the second lifting screw 50 via a second nut fixed therein. When the second motor 8 drives the second lifting screw 50 to rotate via the second reducer 48, the second sliding seat 20 slides up and down along the second slide rail 51.
[0032] like Figure 1 As shown, combined with Figure 2-7 As shown, the aircraft engine assembly platform of the present invention, wherein the first slewing bearing 9 includes a first outer ring, a first inner ring, a supporting base, a third motor 34 and a worm, the first inner ring is fixedly arranged on the supporting base, the first outer ring is rotatably installed on the outside of the first inner ring, the third motor 34 is fixedly arranged on the supporting base, the output shaft of the third motor 34 is fixedly connected to the worm, the outer peripheral surface of the first outer ring is provided with circumferentially arranged external teeth, the worm is engaged with the external teeth, the supporting base is fixedly connected to the first sliding seat 2, and the first outer ring is fixedly connected to one side of the first turntable 33.
[0033] The aircraft engine assembly platform of the present invention, wherein the second slewing bearing 19 includes a second outer ring and a second inner ring, the second inner ring is rotatably installed in the second outer ring, the second inner ring is fixedly connected to the second sliding seat 20, and the second outer ring is fixedly connected to one side of the second turntable 23.
[0034] The second slewing bearing 19 is a prior art, which is a large bearing. Its specific structure and working principle will not be described in detail here.
[0035] The first slewing bearing 9 is of prior art. When the third motor 34 drives the worm to rotate, the worm engages with the outer teeth of the first outer ring. Therefore, under the drive of the worm, the first outer ring rotates relative to the first inner ring and the support base.
[0036] When the third motor 34 drives the first outer ring to rotate relative to the first inner ring and the support base, since the support base is fixedly connected to the first sliding seat 2 and the first outer ring is fixedly connected to the first turntable 33, the first turntable 33 rotates relative to the first sliding seat 2. Since the first C-shaped ring 13 on the first turntable 33 and the second C-shaped ring 14 on the second turntable 23 jointly clamp the aircraft engine 29, the first turntable 33 can drive the second turntable 23 to rotate through the first C-shaped ring 13 and the second C-shaped ring 14, that is, the second turntable 23 rotates relative to the second sliding seat 20 (because the second inner ring and the second outer ring of the second slewing bearing 19 are fixedly connected to the second sliding seat 20 and the second turntable 23, respectively, the second turntable 23 can rotate relative to the second sliding seat 20), thereby enabling the aircraft engine 29 to rotate in a vertical plane.
[0037] like Figure 1 As shown, combined with Figure 2-7As shown, the aircraft engine assembly platform of the present invention, wherein the upper surface of the first C-shaped ring 13 is fixedly provided with a first upper arc-shaped slide rail 30, and the first upper arc-shaped slide rail 30 is arranged along the circumference of the first C-shaped ring 13, and the lower surface of the first upper support plate 32 is fixedly provided with a first upper arc-shaped slider 31, and the first upper arc-shaped slider 31 is slidably installed on the first upper arc-shaped slide rail 30, the lower surface of the first C-shaped ring 13 is fixedly provided with a first lower arc-shaped slide rail 12, and the first lower arc-shaped slide rail 12 is arranged along the circumference of the first C-shaped ring 13, the upper surface of the first lower support plate 10 is fixedly provided with a first lower arc-shaped slider 11, and the first lower arc-shaped slider 11 is slidably installed on the first lower arc-shaped slide rail 12, the upper surface of the second C-shaped ring 14 is fixedly provided with a second upper arc-shaped slide rail 27, and the second upper arc-shaped slide rail 27 is arranged along the circumference of the second C-shaped ring 14, the lower surface of the second upper support plate 25 is fixedly provided with a second upper arc-shaped slider 26, and the second upper arc-shaped slider 26 is slidably installed on the second upper arc-shaped slide rail 27, A second lower arc-shaped slide rail 16 is fixedly provided on the lower surface of the second C-shaped ring 14, and the second lower arc-shaped slide rail 16 is arranged along the circumference of the second C-shaped ring 14. A second lower arc-shaped slider 17 is fixedly provided on the upper surface of the second lower support plate 18, and the second lower arc-shaped slider 17 is slidably mounted on the second lower arc-shaped slide rail 16. The cross-sections of the first upper arc-shaped slide rail 30 and the second upper arc-shaped slide rail 27 are the same. The first upper arc-shaped slide rail 30 and the second upper arc-shaped slide rail 27 form an upper circular slide rail. The first lower arc-shaped slide rail The rail 12 and the second lower arc-shaped slide rail 16 have the same cross-section. The first lower arc-shaped slide rail 12 and the second lower arc-shaped slide rail 16 form a lower circular slide rail. The third driving device includes a fourth motor 24, a first gear 21 and a circular rack 28. The circular rack 28 is fixedly arranged on the outer peripheral side of the circular closed ring along the circumferential direction. The fourth motor 24 is fixedly arranged on the second upper support plate 25. The first gear 21 is fixedly connected to the output shaft of the fourth motor 24, and the first gear 21 is engaged with the circular rack 28.
[0038] A first arc-shaped rack arranged circumferentially is fixedly provided on the outer peripheral side surface of the first C-shaped ring 13, and a second arc-shaped rack arranged circumferentially is fixedly provided on the outer peripheral side surface of the second C-shaped ring 14. The cross-sections of the first arc-shaped rack and the second arc-shaped rack are the same, and the first arc-shaped rack and the second arc-shaped rack form a circular rack 28. When the fourth motor 24 drives the first gear 21 to rotate, since the first gear 21 is engaged with the circular rack 28, and the upper circular slide is slidably installed with the first upper arc-shaped slider 31 and the second upper arc-shaped slider 26, and the lower circular slide is slidably installed with the first lower arc-shaped slider 11 and the second lower arc-shaped slider 17, the first gear 21 can drive the circular rack 28 to rotate, that is, drive the circular closed ring formed by the first C-shaped ring 13 and the second C-shaped ring 14 to rotate around its own axis (at the same time, the aircraft engine 29 clamped inside the circular closed ring also rotates around its own axis). At this time, the upper circular slide slides relative to the first upper arc-shaped slider 31 and the second upper arc-shaped slider 26, and the lower circular slide slides relative to the first lower arc-shaped slider 11 and the second lower arc-shaped slider 17. That is to say, the first C-shaped ring 13 slides relative to the first upper support plate 32 and the first lower support plate 10, and the second C-shaped ring 14 slides relative to the second upper support plate 25 and the second lower support plate 18.
[0039] like Figure 8 、 9 As shown, combined with Figure 1-7 As shown, the aircraft engine assembly platform of the present invention, wherein the first C-shaped ring 13 and the second C-shaped ring 14 are both provided with radially arranged through holes, and a clamping member 15 is installed in the through hole, and the clamping member 15 includes a clamping seat 56, a clamping screw 59 and a clamping block 52, and the clamping seat 56 is U-shaped, and the clamping seat 56 includes a bottom plate 54 fixed in the through hole, and two oppositely arranged side plates 58 are fixed on the bottom plate 54, and a clamping screw 59 is rotatably installed between the two side plates 58, and the arrangement direction of the clamping screw 59 is the same as that of the through hole, and the two side plates 58 are arranged in the same direction. The clamping block 52 is threadedly connected to the clamping screw 59 in the middle, and the base plate 54 is provided with a clamping slide rail 55 with the same arrangement direction as the clamping screw 59. The lower end of the clamping block 52 is fixed with a clamping slider 53, and the clamping slider 53 is slidably installed on the clamping slide rail 55. The upper end of the clamping block 52 is fixed with a clamping plate 36, and the height of the clamping plate 36 is higher than the two side plates 58, that is, the clamping plate 36 is located above the two side plates 58, so that the two side plates 58 will not hinder the clamping block 52 from sliding with the clamping plate 36 to clamp or release the aircraft engine 29.
[0040] In the aircraft engine assembly platform of the present invention, a hand wheel 57 is fixedly connected to the clamping screw 59 , and the hand wheel 57 is located outside the clamping seat 56 .
[0041] The clamping screw 59 is rotatably mounted between the two side plates 58 via bearings. When the clamping screw 59 is rotated by the hand wheel 57, the clamping block 52, which is slidably mounted on the clamping rail 55 via the clamping slider 53, does not rotate with the clamping screw 59 but can only slide along the clamping rail 55. Consequently, the clamping block 52, along with the clamping plate 36, slides radially inward along the first C-shaped ring 13 / second C-shaped ring 14 to clamp the aircraft engine 29, or slides outward to release the aircraft engine 29. When the clamping block 52, along with the clamping plate 36, slides radially inward along the first C-shaped ring 13 / second C-shaped ring 14, it slides radially toward the center of the circular closed loop formed by the first C-shaped ring 13 and the second C-shaped ring 14. Conversely, when the clamping block 52, along with the clamping plate 36, slides radially away from the center of the circular closed loop to release the aircraft engine 29, it slides radially away from the center of the circular closed loop.
[0042] To facilitate clamping aircraft engine 29, several clamping lugs 35 are provided along the circumference of aircraft engine 29. When a clamping plate 36 approaches aircraft engine 29 to clamp it, the clamping plate 36 contacts the clamping lugs 35. Through holes are provided in both the clamping plate 36 and the clamping lugs 35, allowing fasteners such as bolts or pins to be inserted through the through holes in the clamping plate 36 and the clamping lugs 35 to secure the two. After assembling aircraft engine 29, aircraft engine 29 can be released by simply removing the fasteners and moving the clamping plate 36 away from the aircraft engine 29.

[0044] In the aircraft engine assembly platform of the present invention, the specific manner in which the second gear 5 is engaged with the linear rack 44 is as follows: a third gear 6 is provided between the second gear 5 and the linear rack 44, the third gear 6 is rotatably mounted on the first vertical frame 1, and the third gear 6 is engaged with the second gear 5 and the linear rack 44 respectively.
[0045] The fifth motor 45 is fixedly mounted on the first base plate 40 of the first vertical frame 1. The third gear 6 is also rotatably mounted on the first base plate 40 of the first vertical frame 1. Specifically, the third gear 6 is fixedly connected to a shaft, which is in turn rotatably mounted on the first base plate 40 via a bearing. When the fifth motor 45 drives the second gear 5 to rotate, the third gear 6, which is meshed with the second gear 5, also rotates. Since the third gear 6 meshes with the linear rack 44, the third gear 6 causes the entire first vertical frame 1 to slide along the third slide rail 7 via the third slider 43, thereby moving the first vertical frame 1 toward or away from the second vertical frame 22.
[0046] like Figure 1 As shown, combined with Figure 2-9 As shown, when the aircraft engine assembly platform of the present invention is in use, the entire assembly platform can first be moved to a suitable position by the AGV, and then the distance between the first vertical frame 1 and the second vertical frame 22 is increased by the fifth motor 45, and then the aircraft engine 29 is placed between the first C-shaped ring 13 and the second C-shaped ring 14, and then the distance between the first vertical frame 1 and the second vertical frame 22 is reduced by the fifth motor 45 until the first C-shaped ring 13 and the second C-shaped ring 14 are in contact, and the two C-shaped rings are fixed by fasteners to form a circular closed loop, and then the hand wheel 57 is rotated to make the clamping block 52 slide with the clamping plate 36 toward the center of the circular closed loop until the clamping plate 36 contacts the clamping lug 35 on the aircraft engine 29, and then the clamping plate 36 is fixed to the clamping lug 35 by fasteners, thereby clamping the aircraft engine 29 in the circular closed loop. Then, according to actual requirements, the first motor 4 and the second motor 8 are used to simultaneously drive the first sliding seat 2 and the second sliding seat 20 to rise or fall, thereby driving the aircraft engine 29 to rise or fall. After the aircraft engine 29 rises or falls to an appropriate height, the third motor 34 is used to drive the first slewing support 9 and the second slewing support 19, causing the first turntable 33 and the second turntable 23 to rotate simultaneously, thereby causing the aircraft engine 29 to rotate in a vertical plane. After the aircraft engine 29 rotates to an appropriate position, the fourth motor 24 is used to drive the circular closed structure to rotate around its own axis, that is, the aircraft engine 29 rotates around its own axis, thereby facilitating the assembly of the aircraft engine 29. It can be seen that since the present invention clamps the aircraft engine 29 through the relatively arranged first C-ring 13 and the second C-ring 14, it is safer. Since the present invention uses the AGV as the support base, it can be easily moved.
[0047] After completing the assembly of the aircraft engine 29, it is only necessary to use the lifting equipment to lift the engine 29, then remove the fasteners between the clamping lug 35 and the clamping plate 36, then turn the hand wheel 57 to move the clamping plate 36 away from the engine 29, then remove the fasteners between the first C-shaped ring 13 and the second C-shaped ring 14, and then use the fifth motor 45 to increase the distance between the first vertical frame 1 and the second vertical frame 22, and finally use the lifting equipment to lift the engine 29 away.
