[0026] Embodiment

[0027] Generally, the aircraft skin is placed on a storage rack, and then the aircraft skin is clamped and fixed by a clamping structure manually set on the storage rack. Secondly, it is not convenient to adjust and adapt to aircraft skins of different lengths, resulting in a limited scope of application. Moreover, it is not convenient to adjust the support height of the aircraft skin;

[0028] For this reason, please refer to Figures 1-4, the present invention provides an aircraft skin storage rack, comprising: a bottom frame 1 and two symmetrically arranged top trays 2, and a height adjustment assembly 3 is connected between the bottom frame 1 and the two top trays 2; the height adjustment assembly 3 is used to synchronously adjust the heights of the two top trays 2; gravity positioning members 4, the gravity positioning members 4 are all installed on the top trays 2, and the gravity positioning members 4 are used to fix the aircraft skin on the two top trays 2 by means of the gravity of the aircraft skin; an anti-displacement assembly 5, the anti-displacement assembly 5 is installed on the height adjustment assembly 3 and is connected to the two gravity positioning members 4.

[0029] Among them, the cross-section of the bottom frame 1 is in a mouth-shaped structure.

[0030] Furthermore, as Figures 1-4 shown, specifically, in order to facilitate the synchronous adjustment of the heights of the two top trays 2, the height adjustment assembly 3 is provided to include two symmetrically arranged moving plates 31 slidably connected to the top of the bottom frame 1. At the bottom ends of the two moving plates 31, two symmetrically arranged first sliders 32 are fixedly connected. At the top end of the bottom frame 1, two symmetrically arranged first chutes are opened. In the two first chutes, two symmetrically arranged first sliders 32 are slidably fitted. In the middle parts of the two moving plates 31, spline sleeves 33 are rotatably connected. On the outer sides of the two spline sleeves 33, first bevel gears 34 are fixedly connected. Above the two first bevel gears 34, second bevel gears 35 are meshingly connected. The two second bevel gears 35 are fixedly connected to the outer sides of the threaded cylinders 36. The bottom ends of the two threaded cylinders 36 are rotatably connected to the center of the top end of the corresponding moving plate 31. In the inner threaded channels of the two threaded cylinders 36, screws 37 are spirally connected. The top ends of the two screws 37 are fixedly connected to the outer sides of the corresponding top trays 2 through first U-shaped connecting frames 38. The thread directions of the two screws 37 are opposite. In the mounting shaft holes of the two spline sleeves 33, the same spline shaft 310 is fitted. The two ends of the spline shaft 310 are rotatably connected to the bottom frame 1 through bearing seats. The extending parts at the two ends of the spline shaft 310 are fixedly connected with handwheels 311. On both sides of the two threaded cylinders 36, telescopic rods 39 fixedly connected to the top end of the moving plate 31 are provided. The telescopic ends of the telescopic rods 39 are fixedly connected to the outer sides of the corresponding top trays 2 through second U-shaped connecting frames 391.

[0031] Among them, the telescopic rods 39 and the second U-shaped connecting frames 391 are provided to ensure the stable lifting movement of the top trays 2. When adjusting the height, the spline shaft 310 can be rotated through the handwheel 311, so that the two spline sleeves 33 rotate, and the first bevel gears 34 rotate, and the second bevel gears 35 can be driven, so that the two threaded cylinders 36 rotate in opposite directions. With the cooperation of the screws 37, the heights of the top trays 2 are synchronously adjusted to facilitate the adjustment of the storage support height.

[0032] Furthermore, asFigures 1-4 As shown, it is worth specifically explaining that in order to be able to adapt to clamping and limiting of different widths by means of the gravity of the aircraft skin, a gravity positioning member 4 is provided, which includes two symmetrically arranged sliding grooves opened on the top support plate 2. A sliding seat 41 with an I-shaped cross-section is slidably connected in each of the two sliding grooves. One end of the two sliding seats 41 facing each other is fixedly connected to the inner wall of the sliding groove through a spring 411. A first clamping plate 42 and a second clamping plate 43 are respectively movably inserted on the two sliding seats 41. The cross-sections of the first clamping plate 42 and the second clamping plate 43 are both U-shaped structures. One end of the first clamping plate 42 and the second clamping plate 43 away from each other are respectively provided with a first clamping portion 421 and a second clamping portion 431. The first clamping portion 421 and the second clamping portion 431 are respectively in a bent shape. A heavy pressure rod 45 is movably inserted in the middle of the top support plate 2. Push-pull rods 44 are hinged on both side walls at the bottom of the heavy pressure rod 45. The tops of the two push-pull rods 44 are respectively hinged to the bottom end of the corresponding sliding seat 41. Two symmetrically arranged moving channels 47 are opened on one side wall of the top support plate 2 away from the middle of the bottom frame 1. Hand-tightening screws 46 are movably arranged in the moving channels 47. The hand-tightening screws 46 are respectively threadedly connected to threaded grooves opened on the outer wall of the sliding seat 41. The ends of the hand-tightening screws 46 after being tightened are both abutted against the outside of the first clamping plate 42 or the second clamping plate 43.

[0033] Among them, the hand-tightening screw 46 can move in the moving channel 47 along with the movement of the sliding seat 41. When the aircraft skin is not placed on the top support plate 2, the top end of the heavy pressure rod 45 extends out of the top of the top support plate 2, and the top of the heavy pressure rod 45 is parallel to the top of the second clamping portion 431. The heavy pressure rods 45 shown in the drawings are all in the state of being heavily pressed by the aircraft skin, and the spring 411 is in a compressed state in the drawings. The spring 411 is provided so that the heavy pressure rod 45 can move upward and reset when not pressed by gravity. The first clamping portion 421 and the second clamping plate 43 are both provided to adapt to the shapes of both sides of the aircraft skin.

[0034] Furthermore, as Figures 1-4As shown in the figure, it is worth specifically explaining that in order to fix the two top brackets 2 after adjusting the spacing and also limit and fix the two spline sleeves 33, an anti-displacement component 5 is provided, which includes two symmetrically arranged second sliding grooves opened on the two moving plates 31. A second slider 53 with a convex cross-section is slidably connected in each second sliding groove. On one side wall of each second slider 53 facing the spline sleeve 33, an arc-shaped toothed plate 55 is fixedly connected through a connecting rod 54. A vertical toothed plate 56 is fixedly connected to the bottom end of each arc-shaped toothed plate 55. The arc-shaped toothed plates 55 are respectively engaged with a plurality of annularly arranged teeth 57 fixedly connected to the outer wall of the spline sleeve 33. A double-sided toothed plate 58 fixedly connected to the inner wall of the bottom frame 1 is provided between the two vertical toothed plates 56. The vertical toothed plates 56 are respectively engaged with the double-sided toothed plate 58. Guide rods 52 are fixedly connected to the top ends of the second sliders 53. U-shaped synchronous rods 51 are slidably sleeved on the outer sides of the guide rods 52. The top ends of the U-shaped synchronous rods 51 are fixedly connected to the bottom ends of the corresponding sliding seats 41.

[0035] Among them, when the height of the top bracket 2 is adjusted by the height adjustment component 3, the U-shaped synchronous rod 51 can slide on the guide rod 52. When the sliding seat 41 compresses the spring 411, it can synchronously drive the second slider 53 connected to the bottom end of the guide rod 52 to move towards the spline sleeve 33, so that the arc-shaped toothed plate 55 and the vertical toothed plate 56 respectively engage and fix the multiple teeth 57 on the spline sleeve 33 and the double-sided toothed plate 58. The double-sided toothed plate 58 means that racks are provided on both sides.

[0036] In summary: When using this aircraft skin storage rack, the aircraft skin is placed on the two top brackets 2 through a hoisting device. During the placement, under the heavy pressure of the aircraft skin, the two heavy pressure rods 45 move downward simultaneously. With the arrangement of the push-pull rod 44, the two sliding seats 41 on the same top bracket 2 can move relatively towards each other, driving the first clamping plate 42 and the second clamping plate 43 to move relatively towards each other, and enabling the first clamping part 421 and the second clamping part 431 to simultaneously clamp and limit both sides of the aircraft skin. While clamping and limiting, the U-shaped synchronous rods 51 drive the second sliders 53 connected to the guide rods 52 to move towards the spline sleeve 33, so that the arc-shaped toothed plate 55 and the vertical toothed plate 56 are respectively engaged with the multiple teeth 57 on the outer side of the spline sleeve 33 and the double-sided toothed plate 58. Thus, on the one hand, the two top brackets 2 after adjusting the spacing can be quickly limited, and on the other hand, it can prevent the spline sleeve 33 from rotating due to external factors, affecting the stability of the top bracket 2 after height adjustment.
