[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figures 1 to 2 As shown, this embodiment provides a multi-purpose satellite parking rack tooling, including a bottom main frame 1 and multiple satellite docking frames 2.

[0025] The structure of the bottom main frame 1 is as follows Figure 3 As shown, the bottom main frame 1 is the same as the general-purpose satellite support vehicle, which facilitates modification for use with other satellite models in the future. The bottom main frame 1 is welded from 80×80×5mm steel pipes and 5mm steel plates to ensure high overall strength and rigidity. The lower supporting steel frame 11 is composed of steel pipes. The interfaces on the supporting steel frame 11 where equipment needs to be installed are achieved by welding steel plates and then machining them, which can ensure the installation accuracy of the equipment.

[0026] The bottom main frame 1 has a first interface 111 on the lower surface of each corner, a second interface 112 on each corner, a third interface 113 on the upper surface of each corner, and a fourth interface 114 on one of its sides.

[0027] A detachable adapter plate 12 is provided on the upper surface of the bottom main frame 1, and several sets of threaded holes 121 are provided on the adapter plate 12. Each star docking frame 2 is adapted to and detachably connected to a set of threaded holes 121 of the adapter plate 12. Each satellite docking frame 2 is used to carry different types of satellites.

[0028] The structure of the star docking frame 2 is as follows Figure 4 As shown, the satellite docking frame 2 is made of zero magnetic material and has holes that match the interfaces of mass testing platform, magnetic test platform, EMC test platform, etc., so that it can be used for various special tests.

[0029] Specifically, the star docking frame 2 includes a horizontally arranged base plate 22 and vertically arranged transition tubes 21 at each corner; reinforcing plates 23 are respectively arranged between adjacent transition tubes 21 and between transition tubes 21 and base plate 22. The base plate 22 has pre-drilled holes for docking with various test benches.

[0030] The base plate 22 is made of 80×80×5mm aluminum tube and 5mm aluminum plate welded together. The transition tube 21 is made of 80×80×5mm aluminum tube and serves to connect the satellite. The lower ends of the four transition tubes 21 are welded to the aluminum base plate 22. The base plate 22 has multiple threaded holes to cooperate with the adapter plate 12 of the satellite docking frame 2 and is installed and fastened with M10 screws.

[0031] The top plate 24 of aluminum material is welded to the upper end of the transition tube 21. The top plate 24 has 5 threaded holes, of which 4 at the corners are used for docking with the satellite, and the middle one is used as a hoisting hole to install the rotating lifting ring 6. The number and position of the multiple threaded holes on the bottom plate 22 are determined by considering multiple interfaces, and need to be able to dock and install with the interfaces on the quality testing platform, magnetic testing platform, and EMC testing platform.

[0032] A walking mechanism is also installed on the lower surface of the bottom main frame 1. The walking mechanism uses walking casters 3, including two swivel casters and two fixed casters, each with a load capacity of 1000kg. The walking casters 3 are connected to the bottom main frame 1 through the first interface 111. The walking casters 3 can ensure smooth and easy movement within the factory after the vehicle is loaded with satellites.

[0033] Support mechanisms 4 are provided at each corner of the bottom main frame 1. The support mechanism 4 is a hand-cranked rotating support seat, which can lock the position of the bottom main frame 1 by contacting the ground with pressure. The hand-cranked rotating support seat is connected to the bottom main frame 1 through the third interface 113, which can ensure smooth lifting and lowering of the vehicle, easy operation, sufficient load-bearing capacity and a certain function of adjusting the satellite attitude.

[0034] The second interface 112 on the upper surface of each corner of the bottom main frame 1 is used to install the rotating lifting ring 6, so that the bottom main frame 1 and even the parking vehicle tooling can be lifted and moved.

[0035] The traction mechanism 5 is connected to the bottom main frame 1 via the fourth interface 114. The traction mechanism 5 includes a connecting seat and a trailing rod; the connecting seat is connected to the fourth interface 114 by bolts; the trailing rod is hinged to the connecting seat for easy angle adjustment.

[0036] In other embodiments, the traction mechanism 5 can also be replaced by a pushing mechanism, such as a push-pull handle.

[0037] Figure 5 This is a schematic diagram of the state when the satellite docking frame is used alone for lifting. The rotating lifting ring 6 is connected to the top plate 24, and the satellite docking frame 2 can be lifted and moved by the lifting device.

[0038] Figure 6 This diagram illustrates the docking of the vehicle mounting fixture with the satellite. The satellite is mounted on the top plate 24 of the satellite docking frame 2 using bolts.

[0039] The satellite multi-purpose parking rack tooling of this embodiment has the following advantages: The vehicle mounting fixture is assembled from a universal bottom main frame and a satellite docking frame. The universal bottom main frame is convenient for use or modification by other satellite models in the future. The satellite docking frame can be disassembled from the bottom main frame and used independently. The satellite docking frame is made of zero magnetic material and has holes for matching interfaces with mass testing platforms, magnetic test platforms, EMC test platforms, etc., so it can be used for various special tests. Multi-purpose parking rack fixtures can effectively reduce the types and quantities of satellite fixtures to a certain extent, thus saving satellite development costs.
