Description

Technical Field

[0001] The present application relates to the technical field of satellite assembly, and in particular to a five-degree-of-freedom adjustment platform for satellite cabin panel assembly. Background Art

[0002] Currently, an artificial satellite refers to an unmanned spacecraft that orbits the Earth and completes at least one orbit. These satellites are the most numerous, widely used, and fastest-growing spacecraft, primarily used in scientific exploration and research, weather forecasting, land resource surveys, land use, regional planning, communications, tracking, and navigation. Currently, most microsatellites utilize a cabin-panel structure, consisting of solar panels, several cabin panels, and functional components mounted on these panels. These panels are assembled using a five-degree-of-freedom adjustment platform.

[0003] The existing five-degree-of-freedom adjustment platform usually includes a platform body, a support frame that rotates and cooperates with the platform body, and a placement frame that is folded and connected to the support frame. It also includes an adjustment mechanism for driving the support frame to adjust forward and backward, up and down, left and right. When assembling the cabin board, the cabin board is installed on the placement frame. When adjusting the cabin board, the operator rotates the support frame to drive the placement frame and the cabin board to rotate and adjust. After the adjustment is completed, the placement frame is flipped over to drive the cabin board to flip and adjust.

[0004] The above-mentioned related technologies have the defect that when the cabin needs to be rotated and flipped at the same time, the operator needs to operate the support frame and the placement frame separately, which makes the five-degree-of-freedom adjustment platform inconvenient to use.

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a five-degree-of-freedom adjustment platform for satellite cabin panel assembly. Figure 1 and Figure 2 The system comprises a platform body 1, a support frame 2, a placement frame 3 folded and connected to the support frame 2, and an adjustment mechanism 4. The placement frame 3 may be provided with a clamping mechanism (not shown) for clamping the satellite cabin panel. The adjustment mechanism 4 includes an adjustment component 1 for driving the placement frame 3 to rise and fall along the height of the platform body 1, an adjustment component 2 for driving the placement frame 3 to slide and adjust along the length of the platform body 1, and an adjustment component 3 for driving the placement frame 3 to slide and adjust along the width of the platform body 1. Adjustment component 1 can be directly implemented using a hydraulic cylinder and telescopic rod, while adjustment components 2 and 3 can be directly implemented using a motor to rotate a worm gear, which in turn rotates a lead screw, which in turn drives a sliding block threaded on the lead screw to slide. To assemble the satellite cabin panel, the satellite cabin panel is mounted on the placement frame 3. The placement frame 3 is then adjusted in position by manipulating the adjustment mechanism 4, rotating the support frame 2, and flipping the placement frame 3, completing the assembly of the satellite cabin panel.

[0035] Reference Figure 1 and Figure 2The support frame 2 includes an adjustment platform 21 mounted on the adjustment mechanism 4 and a rotating plate 22 that rotates and engages with the adjustment platform 21. The adjustment platform 21 is a disc-shaped structure and is fixedly mounted on the sliding block of the adjustment component 3. The rotating plate 22 is arranged along the height direction of the platform body 1 and has a T-slot formed on it.

[0036] Reference Figure 1-Figure 3 One end of the placement rack 3 is rotatably matched with the top end of the rotating plate 22. A driving device 5 is provided on the adjustment platform 21. When the driving device 5 is started, it can drive the rotating plate 22 to revolve around the central axis of the adjustment platform 21 while rotating. The driving device 5 includes a flipping mechanism 6 for driving the placement rack 3 to flip, a rotating mechanism 7 for driving the rotating plate 22 to rotate, and a linkage mechanism 8 for causing the rotating mechanism 7 to drive the flipping mechanism 6 to rotate.

[0037] Among them, reference Figure 1 and Figure 2 The flip mechanism 6 includes a slider 61 that slides along the height of the platform body 1 and fits on the rotating plate 22; a screw 62 that threads onto the slider 61; and a support rod 63. The slider 61 is a T-shaped block that slides within a T-slot. The screw 62 is arranged along the height of the platform body 1. The rotating plate 22 rotationally supports the screw 62, which is used to drive the slider 61 to slide. One end of the support rod 63 is rotationally engaged with the placement rack 3, and the other end is rotationally engaged with the slider 61. When the screw 62 rotates, it drives the slider 61 to rise and fall, which in turn drives the support rod 63 to rotate, thereby driving the placement rack 3 to flip and adjust.

[0038] Among them, reference Figure 1 and Figure 2 The rotating mechanism 7 includes a connecting frame 71 for driving the rotating plate 22 to rotate, and a driving assembly 72. The driving assembly 72 is used to drive the connecting frame 71 to rotate. The driving assembly 72 includes a gear 721 that rotates with the adjustment platform 21 and is used to drive the connecting frame 71 to rotate, and a driving member 722 fixedly mounted on the adjustment platform 21. The driving member 722 can directly adopt a self-locking motor. The cylinder of the driving member 722 is fixedly connected to the adjustment platform 21, and the output shaft of the driving member 722 is coaxially fixedly connected to the gear 721. The upper surface of the adjustment platform 21 is fixedly provided with a fixing frame 11, which rotatably supports the gear 721. Starting the driving member 722 can drive the gear 721 to rotate.

[0039] Reference Figure 1 and Figure 2The linkage mechanism 8 includes a large ring gear 81 fixedly mounted on the adjustment platform 21 and a second gear 82 mounted on the screw 62. The diameter of the large ring gear 81 is larger than that of the first gear 721. A rotation groove 811 is defined on the upper surface of the large ring gear 81. The rotation groove 811 extends around the large ring gear 81. A rotating block 221 is fixedly mounted at the bottom end of the rotating plate 22, which rotates within the rotation groove 811. The rotating block 221 is an arc-shaped block. The second gear 82 is located between the first gear 721 and the large ring gear 81, and its ends mesh with the large ring gear 81 and the first gear 721, respectively. A connecting rod 12 is fixedly mounted on the lower surface of the second gear 82. One end of the connecting frame 71 is fixedly connected to the first gear 721, and the other end is sleeved on the connecting rod 12.

[0040] Reference Figure 1 and Figure 2 When it is necessary to rotate and flip the placement rack 3, start the driving member 722 to drive the gear 1 721 and the gear 2 82 to rotate. The gear 2 82 revolves around the central axis of the gear 1 721 and rotates around the central axis of the gear 2 82. When the gear 2 82 revolves, it can drive the rotating plate 22 and the placement rack 3 to revolve. When the gear 2 82 rotates, it can drive the screw 62 to rotate, drive the slider 61 to rise and fall, drive the support rod 63 to rotate, and then drive the placement rack 3 to flip, and simultaneously rotate and flip the placement rack 3; when the slider 61 rises, it can drive the support rod 63 to rotate, drive the placement rack 3 to rotate from the horizontal position to the vertical position, and when the slider 61 descends, it can drive the support rod 63 to rotate, drive the placement rack 3 to rotate from the vertical position to the horizontal position.

[0041] Reference Figure 1 and Figure 2 In order to enable the placement rack 3 to be flipped or rotated independently, a lifting device 9 is provided on the screw 62. The lifting device 9 drives the gear 2 82 to descend, and when the gear 2 82 is no longer engaged with the gear 1 721, the rotating mechanism 7 rotates, and the placement rack 3 is driven to rotate and adjust through the connecting frame 71; when the rotating mechanism 7 stops rotating, the screw 62 is rotated, which can drive the placement rack 3 to be flipped and adjusted.

[0042] Among them, reference Figure 1 and Figure 2 The lifting device 9 includes a fixed sleeve 91 fixedly mounted on the screw 62, a sliding sleeve 92 fixedly connected to the gear 2 82, and a lifting assembly 93 for driving the sliding sleeve 92 to rise and fall. The fixed sleeve 91 is a hollow rectangular structure, and the sliding sleeve 92 slides in the fixed sleeve 91 along the height direction of the platform body 1.

[0043] Reference Figure 1 and Figure 2The lifting assembly 93 includes a mounting plate 931 fixedly mounted on the fixed sleeve 91 and a driver 932. The driver 932 can directly adopt a hydraulic cylinder. The cylinder body of the driver 932 is fixedly mounted on the mounting plate 931. The piston rod of the driver 932 is fixedly connected to the sliding sleeve 92 through a rectangular plate and is used to drive the sliding sleeve 92 to rise and fall.

[0044] Reference Figure 1 and Figure 3 A driving mechanism 10 for driving the screw 62 to rotate is provided on the rotating plate 22. The driving mechanism 10 includes a rotating rod 101 fixedly mounted on the screw 62 and a driving member 102 fixedly mounted on the rotating plate 22 and used to drive the rotating rod 101 to rotate. The driving member 102 can directly adopt an electric motor. The cylinder body of the driving member 102 is fixedly mounted on the rotating plate 22. The output shaft of the driving member 102 is coaxially fixed with the rotating rod 101, and when the driving member 102 is not working, the output shaft of the driving member 102 can rotate.

[0045] Reference Figure 1-Figure 3 When it is necessary to perform a separate flip adjustment on the placement rack 3, the driver 932 is started to drive the sliding sleeve 92 to slide in the fixed sleeve 91, and drive the gear 2 82 to descend, and no longer mesh with the gear 1 721. At this time, the driving member 2 102 is started to drive the rotating rod 101 and the screw 62 to rotate in turn, which can drive the slider 61 to rise and fall, and drive the support rod 63 to rotate, so as to flip the placement rack 3; when the gear 2 82 is no longer meshed with the gear 1 721, the driving member 1 722 is started, which can drive the gear 1 721 and the connecting frame 71 to rotate in turn, and drive the rotating plate 22 and the placement rack 3 to rotate and adjust around the central axis of the gear 1 721.

[0046] The implementation principle of a five-degree-of-freedom adjustment platform for satellite cabin panel assembly in an embodiment of the present application is: when the placement frame 3 needs to be rotated and flipped at the same time, the driving member 722 is first started, which in turn drives the gear 721 and the connecting frame 71 to rotate, and drives the rotating plate 22 and the placement frame 3 to revolve around the central axis of the gear 721, and at the same time the placement frame 3 is flipped, thereby realizing simultaneous rotation adjustment and flipping adjustment of the placement frame 3.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
