[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As Figure 1As shown in the figure, an emergency oxygen module interface inspection tooling includes a tooling frame 3, an inspection panel 2, tooling feet 4, a first mounting bracket 1, a second mounting bracket 6, and positioning bolts 5. A sunken square emergency oxygen module inspection panel mounting groove is provided in the middle of the tooling frame 3. The inspection panel 2 is square as a whole, and three adjacent sides are fixedly attached to the emergency oxygen module inspection panel mounting groove, and there is a gap between the other side and the tooling frame 3 for the small door of the emergency oxygen module to pass through after it is opened. The first mounting bracket 1 and the second mounting bracket 6 are symmetrically and fixedly attached to both sides of the two parallel sides of the upper surface of the tooling frame 3 corresponding to the fixed attachment and installation of the inspection panel 2. The positioning bolts 5 are horizontally installed on the first mounting bracket 1 and the second mounting bracket 6. The tooling feet 4 are fixedly installed at the four corner positions below the tooling frame 3.

[0018] The size of the inspection panel 2 is the same as the aircraft interior boundary size of the emergency oxygen module.

[0019] Square holes are provided on the corresponding sides of the gap between the inspection panel 2 and the tooling frame 3 for the lock catches on the small door of the emergency oxygen module to pass through.

[0020] The installation positions of the positioning bolts 5 correspond to the thread interface positions of the emergency oxygen module and the aircraft.

[0021] In a possible embodiment, the width of the gap between the inspection panel 2 and the tooling frame 3 is 10 mm.

[0022] In a possible embodiment, the entire emergency oxygen module interface inspection tooling is made of stainless steel.

[0023] In a possible embodiment, the number of positioning bolts 5 installed on the first mounting bracket 1 is 2; the number of positioning bolts 5 installed on the second mounting bracket 6 is 2.

[0024] According to the second aspect of the present invention, there is provided an emergency oxygen module interface inspection method. As Figure 2 shown, using the above-mentioned emergency oxygen module interface inspection tooling, it is characterized by including the following steps:

[0025] First, place an emergency oxygen module interface inspection tooling on a horizontal plane. Loosen the positioning bolts 5 installed on the first mounting bracket 1 and the second mounting bracket 6 so that the tails of the positioning bolts 5 are inside the first mounting bracket 1 and the second mounting bracket 6. Open the small door of the emergency oxygen module downward and pass it through the gap between the inspection panel 2 and the tooling frame 3, and place it on the surface of the inspection panel 2. Check whether the emergency oxygen module is completely within the sidelines of the inspection panel 2, and check whether all the positioning bolts 5 can be correspondingly connected to the threaded interface positions of the emergency oxygen module and the aircraft.
