[0027] Through in-depth research and improvement exploration of satellite assembly and side panel installation, the applicant discovered that the conventional approach involves fixing the main satellite structure to a satellite parking vehicle, placing four dedicated side panel installation vehicles at corresponding positions around the satellite, and fixing the side panels to designated positions on these vehicles.

The axes around which the first and second rotation directions are located are two mutually perpendicular directions, giving the first side plate rotational motion in two mutually perpendicular directions on the first side. This allows the first side plate to perform attitude adjustment, status maintenance, docking, and sealing operations during installation on the satellite's main structure.

[0042] The second side support platform is fixedly connected to the satellite parking vehicle 2. The second side vertical movement mechanism is installed on the second side support platform.

The axes around which the first and second rotation directions on the second side are located are two mutually perpendicular directions, giving the second side plate rotational motion in two mutually perpendicular directions on the second side. This allows the second side plate to perform attitude adjustment, status maintenance, docking, and cabin sealing operations during installation on the satellite's main structure. The rotation angle after rotation in the second side tilting rotation mechanism can be an acute angle, and the adjustment angle after adjustment in the second side rotation adjustment mechanism can also be an acute angle. The overall horizontal direction, the first side horizontal direction, and the second side horizontal direction of the ground fixture can be the same horizontal direction.

[0048] And / or, the second-side rotary adjustment mechanism is driven to connect to the second-side rotary adjustment handle, so that the second-side rotary adjustment mechanism has a driving function.

[0049] Specifically, such as Figure 1 and Figure 2As shown, the positive X-axis side plate mounting mechanism 3 and the negative X-axis side plate mounting mechanism 5 operate on the same principle, including an X-axis support platform 31, an X-axis horizontal slider rail assembly 32, an X-axis horizontal worm gear assembly 321, an X-axis horizontal motion handwheel 322, an X-axis scissor-type lifting mechanism 33, an X-axis lifting deceleration mechanism 331, an X-axis lifting motion handwheel 332, an X-axis vertical slider rail assembly 34, an X-axis vertical worm gear assembly and motion handwheel 341, an X-axis tilting motion mechanism assembly 35, an X-axis tilting motion handwheel 351, an X-axis tilting deceleration mechanism 352, an X-axis tilting support mechanism 353, an X-axis rotation adjustment mechanism 36, an X-axis rotation adjustment handle 361, and an X-axis side plate fixing frame 37. The X-axis support platform 31 is connected to the satellite parking vehicle 2 via screws and nuts. In practical use, the coordinated use of horizontal, lifting, and vertical motion mechanisms enables linear movement of the side plate in three mutually perpendicular directions. Simultaneously, the organic combination of tilting and rotating motion mechanisms allows for rotation around an axis in two mutually perpendicular directions. Through the combined use of these five motion mechanisms, the X-axis side plate possesses five degrees of freedom, enabling smooth attitude adjustment, state maintenance, docking, and sealing operations during satellite assembly. In the original design, the X-axis side plate mechanism could also have six degrees of freedom, similar to the Y-axis side plate mechanism. However, due to the larger length and weight of the Y-axis side plate, six degrees of freedom are required to successfully complete the satellite sealing operation. The X-axis side plate, being smaller and lighter, has a deviation of no more than 0.5mm between its ends and the main frame during sealing, which does not affect the satellite sealing process. Therefore, considering cost savings and reducing the overall weight of the tooling, the X-axis side plate only requires five degrees of freedom to complete attitude adjustment, state maintenance, docking, and sealing operations during satellite assembly.

[0050] like Figure 1 and Figure 3As shown, the positive Y-direction side plate mounting mechanism 4 and the negative Y-direction side plate mounting mechanism 6 operate on the same principle, including a Y-side support platform 41, a Y-side vertical slider rail assembly 42, a Y-side vertical movement handwheel 421, a Y-side vertical worm gear assembly 422, a Y-side horizontal slider rail assembly 43, a Y-side horizontal movement handwheel 431, a Y-side horizontal worm gear assembly 432, a Y-side tilting slider motion mechanism assembly 44, a Y-side tilting worm gear assembly 441, a Y-side tilting deceleration mechanism 442, a Y-side tilting movement handwheel 443, a Y-side tilting support mechanism 444, a Y-side oblique translation slider rail assembly 45, a Y-side oblique movement worm gear and deceleration mechanism assembly 451, a Y-side oblique movement handle 452, a Y-side rotation adjustment mechanism 46, a Y-side rotation adjustment handle 461, and a Y-direction side plate fixing frame 47. The Y-side support platform 41 is connected to the satellite parking vehicle 2 via screws and nuts. In practical use, the side plate can achieve linear movement in three mutually perpendicular directions through the coordinated use of horizontal, vertical, and oblique motion mechanisms. Simultaneously, the organic combination of tilting and rotational motion mechanisms enables the side plate to rotate around an axis in two mutually perpendicular directions. Through the combined use of these five motion mechanisms, the Y-axis side plate possesses five degrees of freedom, enabling smooth attitude adjustment, status maintenance, docking, and sealing operations during satellite assembly.

[0051] In the detailed design of the positive X-axis side plate mounting mechanism 3, negative X-axis side plate mounting mechanism 5, positive Y-axis side plate mounting mechanism 4, and negative Y-axis side plate mounting mechanism 6, the main function is to achieve linear motion in three directions and rotational motion in two directions. For linear motion in the horizontal and vertical directions, this application uses a fixed slide rail, where the rotational force on the handwheel is converted into thrust through the transmission of a worm gear, thus pushing the slider to move linearly along the slide rail. For rising and falling, a scissor-type lifting mechanism is used, adjusting the distance between the two scissor legs to achieve rising or falling. In specific implementations, a combination of slide rail and slider can also be used. For rotational motion, this application adopts a separate design approach, with the two rotation axes operating independently, achieved by adjusting their respective handwheels. In specific implementations, a universal joint connection can also be used, allowing simultaneous rotational motion in two directions through a single universal joint.

[0052] The X-axis side plate mounting mechanism of this application integrates a worm gear mechanism, a slider guide mechanism, and a scissor-type lifting mechanism. Through the organic combination of these multiple mechanisms, it achieves five degrees of freedom in each direction. The Y-axis side plate mounting mechanism integrates a worm gear mechanism, a slider guide mechanism, and an axial adjustment mechanism. Again, through the organic combination of these multiple mechanisms, it achieves five degrees of freedom in each direction. Compared to previous side plate mounting vehicle operating mechanisms, this design adds rotational and tilting motion, solving the technical problem of precise fit between the side plate and the main satellite structure during satellite assembly.

[0053] In the satellite enclosure sealing process with a trapezoidal structure, the X-axis side panels are installed horizontally from left to right with the main satellite structure, while the Y-axis side panels are installed at an angle from bottom to top. Therefore, the installation mechanisms for the X-axis and Y-axis side panels differ slightly. Both of these side panel installation mechanisms can handle the position, angle, attitude adjustment, and maintenance of the side panels during satellite assembly, achieving a smooth docking and installation between the side panels and the main satellite structure.

[0054] In one embodiment, the satellite parking mechanism includes a bracket and multiple lead screw lifting mechanisms mounted on the bracket. The lead screw lifting mechanisms are used to raise and lower the bracket. A platform on the bracket is used to fix the main structure of the parking satellite. Each lead screw lifting mechanism includes a bevel gear, a lead screw gear, a lead screw, and a transmission trapezoidal nut. The bevel gear is rotatably configured and is connected to the lead screw gear. The rotation of the bevel gear drives the lead screw gear and lead screw to rotate synchronously, pushing the transmission trapezoidal nut on the lead screw to move vertically, thus raising and lowering the lead screw lifting mechanism to fix the bracket to the side plate mounting mechanism. For example, the first side plate mounting mechanism is fixed to the ground; the satellite parking mechanism moves to the first side plate mounting mechanism and is fixed thereto, and the second side plate mounting mechanism is fixed to the satellite parking mechanism. The function of the lifting bracket of the lead screw lifting mechanism is to adjust the entire fixture by raising and lowering it, thereby achieving different heights of the satellite reference distance from the horizontal plane, facilitating optical accuracy measurement during the satellite assembly process.

[0055] The lead screw lifting mechanism is distributed at the four vertices of the rectangle on the support, and a T-shaped bidirectional graduated level is set next to the lead screw lifting mechanism on the support as a reference for the platform leveling and lifting process.

[0056] In one embodiment, the stroke length of the lead screw lifting mechanism is ≥500mm; and / or, the maximum load capacity of the lead screw lifting mechanism is 800kg; and / or, the reduction ratio of the bevel gear and the lead screw gear is 24:1; and / or, the lead screw lifting mechanism has a limiting device to prevent derailment caused by overtravel.

[0057] Specifically, the bottom of the satellite parking vehicle 2 is equipped with a manual screw-driven lifting mechanism. The lifting mechanism has a stroke length of ≥500mm and a maximum load capacity of 800kg per mechanism. The lifting mechanisms are screwed to the bottom of the four corners of the support frame. Each of the four lifting mechanisms has a metal T-shaped bidirectional graduated level on its support frame, serving as a reference for platform leveling and lifting. The lifting mechanism works by using a manual crank to rotate a bevel gear, which drives the gear on the screw to rotate synchronously with the screw, pushing the fixed trapezoidal nut on the screw to move linearly up and down, thus achieving lifting and lowering. The trapezoidal screw drive ensures the lifting mechanism can be locked in any position, ensuring platform stability. The gear reduction ratio is 24:1, effectively reducing the force exerted on the lifting mechanism during operation. The lifting mechanism has a limit device to prevent overtravel and derailment.

[0058] In the detailed design process of the satellite parking vehicle 2, this application adopts a welding-then-assembly method. The satellite parking vehicle 2 is assembled from a base frame, bracket, intermediate support legs, casters, and lifting mechanism. The base frame and bracket are welded from steel rectangular tubing, and then other components are assembled onto the base frame and bracket. Other possible implementation methods include using national standard heavy-duty aluminum alloy profiles, combining various connecting corner blocks with aluminum alloy profiles, and using a fully assembled method to achieve the design and manufacture of the satellite parking vehicle 2.

[0059] The embodiments of this specification also disclose a side plate installation method, which uses any of the above-mentioned multi-functional satellite assembly ground tools to install the side plate onto the satellite main structure.

[0060] This application presents an integrated satellite ground tooling design concept, which utilizes mature design technologies and employs simple and reliable mechanisms through reasonable combination to achieve complex functional requirements. It adopts a standardized, interchangeable, and modular design approach to reduce production and maintenance costs. It enables independent movement in different directions of motion without interference and has a self-locking function at any position.

[0061] The novel multifunctional ground tooling for satellite assembly of this application integrates satellite parking and side panel installation functions, replacing the original five tooling solutions (1 satellite parking vehicle and 2 and 4 side panel installation vehicles) with one tooling. Compared with the original solution, it can greatly reduce the production site area, reduce tooling manufacturing costs, reduce the number of workers in the assembly process, and improve production efficiency.

[0062] The multifunctional satellite assembly ground tooling of this application is fully functional and highly integrated. It achieves the functions that originally required multiple toolings with only one tooling. Compared with the original solution, it can save 35% of the production site area during the production process. The production cost of the tooling is only 20% of the original solution. It saves tooling resources and reduces the number of workers. It is simple to use and flexible to operate.

[0063] This application integrates multiple functions that originally required five sets of tooling into a single tooling unit. It features high integration and solves technical challenges such as complex mechanism motion, the need to prevent interference between multiple moving mechanisms, and complex functions. The design process first uses mechanism motion simulation and analysis to decompose the functions required by each motion mechanism. Then, it solves the aforementioned difficulties through the rational combination of slider guide mechanisms, scissor-type mechanisms, worm gear mechanisms, etc., ultimately achieving the integration of multiple functions into a single tooling unit.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
