Description

Technical Field

[0001] The present invention relates to the field of satellite technology, and in particular to a vertical flip side panel satellite mounting method and device, and in particular to a vertical flip side panel satellite mounting method and device suitable for rapid assembly and disassembly of a single unit in a satellite cabin. Background Art

[0002] With the continuous release of domestic constellation satellite plans, the mission volume of small satellites below 1000 kg has increased dramatically. Most small satellites have compact structures and strict requirements on product weight control. It is difficult to disassemble and assemble products in the cabin. For example, a box-type satellite has a main structure composed of 6 surface structural panels. The bottom plate is used as the satellite-rocket docking surface, and the top plate is the main functional payload part. Most single machines are arranged on the top plate. However, due to the influence of the rocket envelope, the design distance between the top plate and the bottom plate is small. According to the traditional method of removing the side panels, there is still not enough operating space to remove the single machine in the cabin. The removal risk of most single machines is high, and specific auxiliary tooling needs to be customized. At the same time, the line of sight for plugging and unplugging connectors of the single machine in the cabin is blocked, and most connectors are blindly plugged and unplugged, which poses great operational risks.

[0003] The traditional side panel removal methods generally include parallel docking and horizontal flip docking. Parallel docking of side panels requires sufficient length margin for the power-on cables of the side panels. There will be a large number of cables that cannot be tied and fixed when the cabin is closed, and the risk and weight of satellite development are difficult to control. The horizontal flip docking of side panels will occupy the standing space of surrounding operators, and the risk of difficulty in disassembling and assembling single units on the inside of the cabin will increase. For example, if there are cable connectors facing inward on the top panel, they still cannot be plugged in normally. At the same time, when the height dimension of the side panels is large, the cable length is long during cable wiring, and the cable weight and development cost are difficult to control. In view of the above problems, it is urgent to design a new method to solve the above defects. Summary of the invention

[0004] In view of the defects in the prior art, the object of the present invention is to provide a vertical flip-type side panel star mounting method and device.

[0005] A vertical flip side panel star installation method provided by the present invention comprises the following steps:

[0013] Step 8: Use the flipping mechanism to simulate the side panel flipping and docking for multiple times. During the flipping process, timely adjust the binding state of the active cables at the flipping joint to prevent the cables from being excessively bent, pulled, and squeezed.

[0014] Step 9: Turn over the simulated docking side panel to dock with the simulated star structure, and install the reset pins and connecting fasteners;

[0015] Step 10: When a single unit in the cabin needs to be temporarily removed, remove the fasteners connecting the simulated docking side panel.

[0028] 3. The present invention can adapt to the side panel flipping installation in working conditions such as horizontal axis flipping, oblique axis flipping, and vertical flipping by installing the flipping mechanism at different angles.

[0110] The hinge 19 provides an installation interface for the side panel interface adapter plate 17 and serves as the main flip axis. The hinge 19 and the flip axis of the 7-combination hinge 19 are coaxially installed to jointly support the weight of the side panel interface adapter plate 17 and the simulated docking side panel 3 after installation.

[0111] The side panel interface adapter plate 17 is used to provide a simulated docking side panel 3 installation interface. It is made of a 25mm aluminum alloy plate as a whole. According to the force simulation analysis, the middle non-load-bearing area is hollowed out for weight reduction, and 4 sets of weight reduction grooves are processed on the back.

[0112] The rotating support block 22 is used to connect the driving flange 23 and the side plate interface adapter plate 17, and convert the pitch circle distribution interface connection into a linear distribution interface connection.

[0113] The reducer support plate 24 is connected to the lower end of the fixed support plate 16 to provide a mounting interface for the worm gear reducer 15 and is processed with an arc-shaped notch to provide temporary fixation when simulating the flipping of the docking side plate 3.

[0114] The conformal block 21 is designed as a triangular structure, which is used to connect and fix the support half-box reducer support plate 24 to ensure the connection strength of the reducer support plate 24.

[0115] The worm gear reducer 15 serves as the main driving mechanism of the flipping mechanism 2, and the reduction ratio is selected as 1:10. The power input end is connected to the driving handwheel 13, the output shaft of the worm gear reducer 15 is coaxially installed with the rotation axis of the 7-combination hinge 19, and the output end is connected to the lower end of the side panel interface adapter plate 17. When the first adjustment handwheel 13 is driven to rotate, the side panel interface adapter plate 17 and the simulated docking side panel 3 are driven to rotate along the rotation axis of the hinge 19.

[0116] The driving flange 23 is used to connect the output shaft of the worm gear reducer 15 and the rotating support block 22, converting the axial key connection into a planar pitch circle distribution interface connection.

[0117] The transmission shaft 14 and the first adjusting hand wheel 13 are used to provide power for the vertical flipping of the simulated docking side plate 3 , and the simulated docking side plate 3 is driven to slowly flip and dock by manually rotating the hand wheel clockwise or counterclockwise.

[0118] The side panel fixing block 26 is used to lock and support when the mounting surface of the simulated docking side panel 3 is flipped to be parallel to the fixed support plate 16. In this state, the flipping mechanism 2 is in a full-freedom locking state with good stability, and can be used to simulate the transportation and flipping of the docking side panel 3.

[0119] The simulated docking side panel 3 is the main dismantling object before and after the disassembly and assembly of the single unit 4 in the cabin. After its dismantling, the normal dismantling of all the products in the satellite cabin can be met.

[0120] The simulated satellite structure 5 is the main operation object for dismantling the single unit 4 in the cabin. Its configuration is a typical single-cabin box-type structure, which is a typical small satellite product layout structure. It is characterized by a compact structural layout, the connectors of the single unit 4 in the cabin facing inward, and the operating space in the cabin is limited. Under the condition that the simulated docking side panel 3 is not dismantled, the single unit 4 in the satellite cabin cannot be normally dismantled.

[0121] The satellite parking adapter tool 7 is mainly used as an interface adapter tool. The upper end surface is the product docking surface, providing a high-precision product docking interface and flatness. The lower end is docked with the factory's universal satellite parking rack 8 to achieve effective docking between the product and the satellite parking rack 8.

[0122] The satellite parking rack 8 serves as the main parking device for the simulated star and can meet the needs of satellite parking and transportation.

[0123] The present invention provides a more universal side panel installation method for the assembly and disassembly of a single unit 4 in a small satellite cabin with a compact layout, and has a good operating space when the single unit 4 in the cabin is assembled and disassembled, avoiding multiple plugging and unplugging of the single unit connector in the side panel cabin and excessively redundant design of the cable length, effectively reducing the risk of satellite development and significantly improving the satellite development efficiency and maintainability.
