Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to an inspection jig for an aircraft cabin door. Background Technique
[0002] The aircraft cabin door is the door connecting the aircraft cabin and the external environment. The metal structure of the aircraft cabin door is a key component to ensure the safety of the aircraft. The aircraft cabin door needs to be regularly inspected and maintained during use to ensure that its performance meets the safety requirements. Correct material selection, manufacturing process, effective structural design, and maintenance can effectively ensure the safety and service life of the aircraft cabin door. The existing inspection jigs for aircraft cabin doors have single functions. When inspecting the aircraft cabin door, it is usually necessary for the staff to perform inspection operations around the aircraft cabin door, which is rather inconvenient. Moreover, the existing jigs have a poor fixing effect on the aircraft cabin door. Fixing too tightly may cause deformation of the aircraft cabin door, and fixing too loosely may cause the aircraft cabin door to become loose, resulting in poor practicability.

Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Embodiment 1:
[0020] As Figures 1-3 shown, the present utility model provides an inspection jig for an aircraft cabin door, which includes a base 1. A driving motor 3 is fixedly connected inside the base 1. The output end of the driving motor 3 is fixedly connected to a connecting rotating shaft 4. The top end of the connecting rotating shaft 4 is fixedly connected to a placement table 5. Support balls 6 are rotatably connected to the lower surface of the placement table 5. At the edge of the upper surface of the placement table 5, a first cylinder 7 is fixedly connected. The top end of the first cylinder 7 is fixedly connected to a fixed seat 8. A second cylinder 9 is fixedly connected inside the fixed seat 8. The output end of the second cylinder 9 is fixedly connected to a pressure sensor 10. A rubber block 11 is fixedly connected to the outer surface of the pressure sensor 10. A control box 12 and a detection column 14 are fixedly connected to the upper surface of the base 1. An operation screen 13 is fixedly connected to the outer surface of the control box 12. A camera 15, an ultrasonic transmitter 16, and an ultrasonic receiver 17 are fixedly connected to the outer surface of the detection column 14.
[0021] Specifically, a universal wheel with a brake 2 is fixedly connected to the lower surface of the base 1. The outer surface of the connecting rotating shaft 4 penetrates through the base 1 and extends to the outside.
[0022] Specifically, the placement table 5 is arranged above the base 1. The number of the support balls 6 is several, and the bottom of the support balls 6 is in contact with the upper surface of the base 1.
[0023] Specifically, the first cylinder 7, the fixed seat 8, the second cylinder 9, the pressure sensor 10, and the rubber block 11 are symmetrically arranged on the upper surface of the placement table 5.
[0024] Specifically, the driving motor 3, the first cylinder 7, the second cylinder 9, the pressure sensor 10, the camera 15, the ultrasonic transmitter 16, and the ultrasonic receiver 17 are all electrically connected to the control box 12.
[0025] The working principle and beneficial effects of the above embodiments.
[0026] During use, place the aircraft cabin door on the placement table 5 and position it between the two rubber blocks 11. Simultaneously extend and retract the two first cylinders 7 to drive the second cylinder 9 to lift to an appropriate height. Then extend the second cylinder 9 so that the two rubber blocks 11 abut against both sides of the aircraft cabin door until the pressure value detected by the pressure sensor 10 reaches the preset pressure value suitable for the aircraft cabin door, ensuring that the aircraft cabin door is fixed with an appropriate acting force. Since the rubber blocks 11 are elastic themselves, they can not only prevent the aircraft cabin door from being worn when fixed but also deform according to the curvature of the aircraft cabin door surface during fixation, resulting in a better fixing effect. Start the drive motor 3 to make the connecting rotating shaft 4 drive the placement table 5 to rotate, thereby making the aircraft cabin door rotate automatically, facilitating the detection by the staff. When the placement table 5 rotates, the supporting balls 6 roll on the upper surface of the base 1, which can not only provide support for the placement table 5 but also reduce wear in the form of rolling friction. Use the camera 15 to capture images of the aircraft cabin door, transmit them to the control box 12 for information processing, and then display them on the operation screen 13. Use the ultrasonic transmitter 16 and ultrasonic receiver 17 to transmit and receive ultrasonic waves to finely detect the defect conditions of the aircraft cabin door.
