[0035] The upper ring rib fixing assembly 300 is fixedly mounted on the base 100 and is used to fix the lower ring rib of the UAV air inlet 700;

[0036] The front plugging cover assembly 400 is fixedly mounted on the base 100 and is used to plug the front port of the drone air inlet 700;

[0037] The rear plugging cover assembly 500 is fixedly mounted on the base 100 and is used to plug the rear port of the drone air inlet 700.

[0038] Specifically, the base 100 is formed by welding square tubes, and the whole base 100 is a frame structure.

[0039] In order to verify the mechanical properties of the carbon fiber composite materials and the wave-absorbing composite materials used in a certain type of UAV air inlet 700 and the load-bearing capacity of the air inlet structure, an air inlet stamping test is required. At this time, a certain type of UAV air inlet 700 needs to be installed on the supporting tooling system of the utility model. When installing the air inlet, it is necessary to first perform mechanical installation based on one side end cover as a reference, and then connect the air inlet ribs to the tooling to complete the subsequent test.

[0040] Furthermore, the lower ring rib fixing assembly 200 includes lower ring rib support columns 201 installed on both sides of the base 100 , and lower ring rib connecting plates 202 are fixed inside the two lower ring rib support columns 201 .

[0041] Specifically, multiple groups of lower ring rib fixing components 200 can be designed according to the specifications and dimensions of the UAV air inlet 700. The lower ring rib support column 201 also adopts a square tube and is fixed on the base 100. Multiple lower ring rib support columns 201 are arranged on the same side, and the tops are connected together by a cross plate 203; the inner side of the lower ring rib connecting plate 202 is processed to conform to the lower ring rib, and the connection between the lower ring rib connecting plate 202 and the lower ring rib support column 201 is processed into an L-shaped folded edge.

[0042] It should be noted that the arrangement of multiple sets of lower ring rib fixing assemblies 200 is to adapt to the longer specifications of the UAV air inlet 700, making the support more reliable. Multiple lower ring rib support columns 201 are connected by a cross plate 203 to further enhance the reliability of the support; the L-shaped folding edge facilitates the fixed connection between the lower ring rib connecting plate 202 and the lower ring rib support column 201.

[0043] Furthermore, the upper ring rib fixing assembly 300 includes upper ring rib support columns 301 installed on both sides of the base 100 , and the two upper ring rib support columns 301 are connected via an upper ring rib connecting plate 302 .

[0048] Furthermore, both ends of the upper ring rib connecting plate 302 are connected to the upper ring rib supporting column 301 via two upper ring rib connecting ear plates 303 .

[0049] It should be noted that since the upper ring rib support column 301 is fixed on both sides of the base 100, the distance between the two upper ring rib support columns 301 is larger than the distance between the two lower ring rib support columns 201. In order to ensure that the upper ring rib connecting plate 302 is more closely connected with the UAV air inlet 700, an upper ring rib connecting ear plate 303 is provided to eliminate the impression caused by the larger distance.

[0050] Furthermore, the front blocking cover assembly 400 includes a front blocking cover support plate 401 fixed on the base 100 , and a front cover plate 402 is mounted on the front blocking cover support plate 401 .

[0054] Furthermore, it also includes a lower rib fixing assembly 600, which is fixedly mounted on the base 100 and is used to fix the lower rib of the drone air inlet 700.

[0055] Specifically, the lower rib fixing assembly 600 is an L-shaped connecting plate.

[0056] It should be noted that the lower rib fixing assembly 600 further improves the reliability of the support of the UAV air inlet 700.
