[0002] In order to ensure that the internal system equipment can be connected to the outside, a certain number of airtight boxes need to be installed on an airtight aircraft. Currently, airtight boxes are installed on jigs during the aircraft assembly stage. Due to the limitations of the jigs, the airtight boxes are difficult to position during the installation process, and often require two operators to collaborate on the installation on both sides of the airtight box. The inner operator is responsible for positioning the airtight box, and the outer operator is responsible for making holes and locating pins. However, during the hole making process, the inner operator is prone to force loss, which leads to the positioning offset of the airtight box. If the operator does not correct it, the final installation position of the airtight box will deviate, resulting in insufficient rivet margins, which affects the position of the parts installed together with the airtight box.

[0003] At the same time, in order to improve the performance of the aircraft, there are cases where the airtight box is moved or added to the delivered aircraft. At this time, due to the small construction space on the aircraft, the positioning of the airtight box requires two operators to work closely inside and outside the aircraft, which greatly increases the difficulty.

[0019] The present invention will be further described below in conjunction with the accompanying drawings:

[0020] like Figure 1 As shown, the utility model proposes to provide an airtight box positioning tool, which mainly includes a positioning component and a tensioning component; wherein the fixing component includes 2 guide rails 1 and 2 rubber pads 7; the tensioning component includes 1 clamping block 4, 1 connecting strip 2, 2 sliders 3, 2 connecting columns 8, 1 screw rod 5, 1 stopper 6, 1 rubber pad with holes 9, and 1 pin rod 10.

[0021] In the positioning assembly, the guide rail 1 is an aluminum profile, and the surface is anodized and oxidized. There is a convex groove inside it, which mainly provides a sliding track for the slider 3 and limits one degree of freedom of the slider 3; the rubber pad 7 is a rubber material, and its main function is to protect the aircraft skin and prevent the aircraft skin from being crushed by the guide rail 1. In the positioning assembly, the length of the guide rail 1 can be changed according to the length of the required positioning airtight box to achieve a wider range of applications; the length of the rubber pad 7 varies according to the length of the guide rail 1, and the contact surface between the guide rail 1 and the aircraft skin is fully covered.

[0022] In the tensioning assembly, the block 4 is an aluminum alloy part with a threaded hole in the middle, which matches the thread of the screw rod; the connecting bar 2 is an aluminum profile, and the surface is anodized and oxidized, and there is a groove inside it, which mainly provides a sliding track for the screw rod 5, while making the screw rod 5 have only one degree of freedom; the slider 3 is an aluminum alloy part, which mainly slides in the guide rail 1; the connecting column 8 is an aluminum alloy part, and its main function is to connect the slider 3 and the connecting bar 2; the screw rod 5 is made of steel material and hard chrome treated, with a thread on the upper end and a pin hole on the lower end; the stopper 6 is an aluminum alloy part, with a square hole in the middle, which is square with the cross-section of the lower end of the screw rod, and the end has a pin hole and matches the pin rod 10; the pin rod 10 is an aluminum alloy part, which is mainly used to limit the movement of the stopper 6; the perforated rubber pad 9 is made of rubber material, and its main function is to protect the airtight box and prevent the airtight box from being crushed by the stopper 6.
