Description

Technical Field

[0001] The present invention relates to the field of spacecraft technology, and in particular to a multifunctional integrated flipping device for a flat-panel satellite. Background Art

[0002] During the development process, flat-panel satellites need to be assembled and tested in multiple states, such as horizontal and vertical. The traditional satellite flipping solution is to use a side panel car or a two-axis turntable. When using this type of tooling, one side of the flat-panel satellite is connected to the tooling. Most of the connection between the satellite and the tooling is interfered by the tooling and cannot perform related work on the satellite. After the work on one side of the flat-panel satellite is completed, the satellite needs to be flipped after replacing the tooling to perform work on the other side. The satellite flipping and attitude adjustment process is complicated, and the tooling needs to be replaced many times, which is inefficient. There are also risks of hooking and bumping during the satellite flipping and tooling replacement process. When there is a need for flat-panel satellites to work on both sides at the same time, the current equipment solution cannot solve this problem. Summary of the invention

[0049] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0050] The present invention provides a flat-panel satellite multifunctional integrated flip device, such as Figure 1 As shown, it includes a base module, a flip module, and a rotation module. The base module is used for overall support. The base module includes a support base 11 and an L-shaped guide rail 4. The L-shaped guide rail 4 is arranged on the support base 11. The L-shaped guide rail 4 is positioned on the support base 11 through two guide rail brackets 8. Three universal casters 6 are installed at the bottom of the support base 11. The support base 11 is installed with three locking struts 7. The locking struts 7 are arranged on the support base 11. The height is adjusted by the internal lead screw 18. The base of the locking strut 7 is equipped with a support nut 16 for support. The base of the locking strut 7 is equipped with a universal ball head 17. In actual use, the equipment is moved and transported as a whole through the three universal casters 6. The L-shaped guide rail 4 is provided with a handrail 13, which facilitates the movement of the device. After the flat-panel satellite 1 is in place, the support nut 16 of the rotating locking strut 7 is fixed and locked in position. At the same time, the height of the three locking struts 7 is adjusted to level the equipment as a whole, including coarse adjustment and fine adjustment. When the position of the flat-panel satellite 1 needs to be fine-tuned (finely adjusted), the universal ball head 17 at the bottom of the locking support rod 7 is screwed out, and the position of the flat-panel satellite 1 can be fine-tuned through the three universal ball heads 17 .

[0051] The flip module includes a flip frame 3, a slider 5, a rocker mechanism 10, a lead screw 12, a first hand wheel 14 and a reducer 19. Two sliders 5 are installed on the flip frame 3. The L-shaped guide rail 4 has two vertically arranged slide rails. The two sliders 5 can slide in the two slide rails on the L-shaped guide rail 4 respectively. The flip frame 3 is driven by the rocker mechanism 10, and the rocker mechanism 10 is driven by the lead screw 12. By rotating the first hand wheel 14, the reducer 19 can be driven to drive the lead screw 12 to move, and the lead screw 12 drives the rocker mechanism 10 to move. The rocker mechanism 10 drives the flip frame 3 to flip through the movement of the slider 5 on the L-shaped guide rail 4, thereby realizing the flipping of the flat-panel satellite 1 from horizontal to vertical direction.

[0052] Specifically, if Figure 1 , Figure 2 , Figure 4 As shown, two sliders 5 are arranged at both ends of one side of the flip frame 3, the middle part of the rocker mechanism 10 is rotationally matched with the support base 11, the front end of the rocker mechanism 10 is rotationally matched with one side of the flip frame 3, the lower end of the lead screw 12 is rotationally matched with the rear end of the rocker mechanism 10, and the upper end of the lead screw 12 is connected to the reducer 19. The reducer 19 is capable of driving the lead screw 12 to move upward, and then driving the rear end of the rocker mechanism 10 to rotate around the axis that is rotationally matched with the support base 11, so that the two sliders 5 slide on the L-shaped guide rail 4 to switch between the horizontal state and the longitudinal state.

[0053] It should be noted that the support base 11 is installed with a protection frame 15 , the size of which is larger than the outer envelope of the flat-panel satellite 1 in the flipped state, and can protect the flat-panel satellite 1 during the flipping process of the flat-panel satellite 1 .

[0054] like Figure 5 As shown, the rotation module includes a satellite bracket 2 and a rotating device 9. The satellite bracket 2 is divided into two. One satellite bracket 2 is configured on one side of the flip frame 3 through the rotating device 9, and the other satellite bracket 2 is configured on the other side of the flip frame 3 through the pin shaft 21. The two sides of the flat-panel satellite 1 can be assembled on the two satellite brackets 2 respectively. In actual application, the rotating device 9 is driven to rotate by the second hand wheel 20 connected to the rotating worm mechanism to realize 360° rotation of the flat-panel satellite 1 around the axis direction.

[0055] The principle of flipping the flat panel satellite 1 from the horizontal state to the vertical state is as follows:

[0056] like Figure 6As shown, the flat-panel satellite 1 in a horizontal state is arranged on the flip frame 3, and the first hand wheel 14 is rotated to drive the reducer 19 to drive the lead screw 12 to move upward, and the lower end of the lead screw 12 drives the outer end of the rocker mechanism 10 to move upward, and the rocker mechanism 10 rotates around the middle rotation axis to drive the inner end of the rocker mechanism 10 to drive the flip frame 3 to slide and flip on the L-shaped guide rail 4 through the slider 5, and finally the flat-panel satellite 1 is flipped to a vertical state.

[0057] The principle of the rotation of the flat-panel satellite 1 in a horizontal state around its axis is as follows:

[0058] like Figure 7 As shown, the flat-panel satellite 1 in a horizontal state is arranged on the flip frame 3, and the second hand wheel 20 can drive the rotating device 9 to rotate. The rotating device 9 is connected to a satellite bracket 2, thereby driving the satellite bracket 2 to rotate, so that the flat-panel satellite 1 mounted on the satellite bracket 2 rotates, and the flat-panel satellite 1 is rotated 360° around the axis direction.
