Description

Technical Field

[0001] The invention relates to the field of aircraft manufacturing equipment, in particular to an aircraft boarding door flipping device and a use method thereof. Background Art

[0002] In the aircraft manufacturing process, a large number of parts assembly processes are involved. Taking the assembly of aircraft boarding doors as an example, when assembling the internal mechanisms and finished parts, the aircraft boarding doors need to be adjusted and fixed at different angles to improve the assembly openness and accessibility, and facilitate the workers' operation. At the same time, the aircraft boarding door assembly process is also divided into different assembly stations, and the assembly of aircraft boarding doors needs to be transferred between different assembly stations. For this reason, it is very necessary to design a device that combines aircraft attitude adjustment, transfer, and compatible automated distribution functions, which can greatly improve the accessibility of manual assembly and the efficiency of transfer between stations.

[0003] Take the patent application with announcement number CN217456383U as an example, which involves a flipping device for an aircraft cabin door. The core of the solution is to set a rotating frame on a fixed bracket, fix the aircraft cabin door on the rotating frame, and then drive the rotating frame to rotate through a corresponding lifting device, so as to adjust the angle of the aircraft cabin door on the rotating frame. However, this solution has the following defects: First, the rotation of the rotating frame requires an additional lifting device to drive, resulting in a complex structure of the flipping device and difficulty in angle adjustment; second, the flipping device can only be fixed at a certain assembly station, and cannot be transported or lifted between multiple assembly stations; third, the flipping angle of the rotating frame is limited, and during the assembly process, the ability to adapt to multi-part multi-angle assembly is insufficient. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an aircraft boarding door flipping device and a use method thereof, which can conveniently and reliably realize the angle adjustment requirement during the assembly process of the aircraft boarding door.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an aircraft boarding door flipping device includes a main frame and support frames respectively arranged at both ends of the main frame, the support frames are arranged in the vertical direction, and a positioning frame for fixing the boarding door is arranged between the support frames. The positioning frame includes a positioning rod and a pair of lateral fixing seats, the positioning rod is a bending structure protruding downward, the two ends of the positioning rod are rotatably arranged on the support frame, and the lateral fixing seats are respectively fixedly arranged on both sides of the positioning rod; the positioning frame includes a clamping mechanism, and the clamping mechanism is arranged at the end of one end of the positioning rod.

[0006] Furthermore, the connection line between the two ends of the positioning rod is arranged in the horizontal direction, and the height of the position where the overall center of gravity of the positioning frame and the boarding door is located is lower than the height of the connection line between the two ends of the positioning rod.

[0007] Furthermore, the positioning frame includes an adjusting disc and a disc rotating shaft. The disc rotating shaft is vertically arranged on the adjusting disc. The adjusting disc is arranged along the vertical direction. The adjusting disc can be rotatably arranged on the supporting frame through the disc rotating shaft. The adjusting disc is fixedly arranged at the end of one end of the positioning rod.

[0008] Furthermore, the positioning frame includes a positioning pin, which can be slidably set on the support frame. The adjusting disc has fixing holes evenly distributed around the center of the adjusting disc. The positioning pin is set in one of the fixing holes to lock the adjusting disc.

[0009] Furthermore, the pressing mechanism is fixedly arranged on the wall surface of the adjusting disc facing the positioning rod.

[0010] Furthermore, the clamping mechanism includes an elongated clamping buckle, a clamping knob and a knob seat. The clamping buckle is arranged between the clamping knob and the knob seat. One end of the knob seat and the clamping buckle are both arranged on the adjusting disk. The clamping buckle passes through the threaded engagement between the clamping buckle and the knob seat. Tightening the clamping knob drives the clamping buckle to deform so that the clamping buckle can clamp the fixed boarding gate.

[0011] Furthermore, a flexible buffer pad is provided on the wall surface where the top surface of the positioning rod contacts the fixed boarding door.

[0012] Furthermore, the flexible buffer pad is a rubber buffer pad or a foam buffer pad.

[0013] Furthermore, rollers are arranged at the bottom of the main frame, and lifting holes are arranged on the lateral fixing seats.

[0014] The method for using the aircraft boarding door flipping device comprises the following steps:

[0015] a. Lift the boarding door to the assembly station where the positioning frame is located by the lifting rod, then set the boarding door arc surface on the outside of the boarding door downward, and then set the boarding door arc surface on the flexible buffer pad on the top surface of the positioning rod;

[0016] b. Thread the lateral fixing seat into the threaded hole at the corresponding position on the fixed boarding door, and tighten the clamping knob to allow the clamping buckle to fix the boarding door clamping end of the fixed boarding door;

[0017] c. Turn the adjustment disc to adjust the boarding door to the desired rotation angle, then place the positioning pin in the corresponding fixing hole on the adjustment disc and lock the adjustment disc to fix the rotation angle of the boarding door;

[0018] d. Complete the assembly operation at the required rotation angle in step c, then pull out the positioning pin from the fixing hole, rotate the adjustment disc to the new rotation angle and lock it again;

[0019] e. After the assembly is completed at the assembly station, the aircraft boarding door flipping device and the boarding door fixed on the aircraft boarding door flipping device are transferred to the next assembly station through rollers, or the lifting rod of the boarding door is set in the lifting hole of the lateral fixing seat to thereby lift the aircraft boarding door flipping device and the boarding door fixed on the aircraft boarding door flipping device to the next assembly station.

[0020] The beneficial effects of the present invention are as follows: 1. When fixing the boarding door, since the positioning rod is a bending structure protruding downward, it can correspond to the boarding door arc surface of the boarding door, and then the boarding door arc surface is well arranged. Through the clamping mechanism and the lateral fixing seat, the boarding door is quickly fixed and supported, reducing the assembly difficulty between the boarding door and the aircraft boarding door flipping device. 2. The connection line at both ends of the positioning rod is arranged in the horizontal direction, and the height of the position where the overall center of gravity of the positioning frame and the boarding door is lower than the height of the connection line at both ends of the positioning rod. Such an arrangement method can make the boarding door just fixed, the center of gravity of the boarding door is at a lower position as a whole, and this is the initial state. After the center of gravity of the boarding door is raised and locked due to flipping, the boarding door will be in a trend of moving downward to the initial state. Once the lock is released, the boarding door can naturally return to the above-mentioned initial state under the action of gravity, thereby reducing the difficulty in the flipping process, thereby the external equipment required to drive the boarding door to return to the initial state can also be omitted, so that the operator can manually flip the boarding door. 3. The center of gravity of the boarding door is at a relatively low position as a whole, which can reduce the risk of the aircraft boarding door flipping device tipping over during transportation using rollers, thereby ensuring production safety. 4. The matching mode of the adjusting disc and the positioning pin makes the locking operation of the aircraft boarding door after flipping convenient and reliable. 5. The matching mode of the fixing hole and the positioning pin can make the flipping angle of the aircraft boarding door more accurate. The present invention is particularly suitable for the assembly process of aircraft boarding doors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 The illustrated embodiment is an embodiment of an aircraft boarding door flipping device. Four rollers 11 are provided at the bottom of the main frame 1, which are used to realize the transfer of the aircraft boarding door flipping device and the boarding door 4 between different assembly stations by ground rolling transportation. Among them, the main frame 1 can be additionally provided with an AGV traction interface, that is, an automatic guided vehicle traction interface, combined with a traction-type AGV to realize unmanned automatic transportation of the boarding door 4. Support frames 12 are respectively provided on the left and right sides of the main frame 1 in the vertical direction, and a height adjustment rod 13 is sleeved in the support frame 12. The height adjustment rod 13 slides up and down along the direction of the support frame 12. When sliding to the desired height position, the height adjustment rod 13 is locked by a buckle or a latch, thereby realizing the height adjustment of the two ends of the positioning rod 3.

[0026] The right end of the positioning rod 3 is fixedly provided with a secondary rotating shaft fixing seat 17, and the secondary rotating shaft fixing seat 17 is rotatably provided on the height adjustment rod 13 on the right side through the secondary rotating shaft 16. The left end of the positioning rod 3 is fixedly provided on the adjustment disk 2, and the adjustment disk 2 is rotatably provided on the height adjustment rod 13 on the left side through the disk rotating shaft 14. On the adjustment disk 2, a clamping buckle 22 is provided between a clamping knob 23 and a knob seat 21, and one end of the knob seat 21 and the clamping buckle 22 are both provided on the adjustment disk 2, and the clamping buckle 22 passes through the threaded engagement between the clamping buckle 22 and the knob seat 21, and tightening the clamping knob 23 drives the clamping buckle 22 to deform so that the clamping buckle 22 clamps the fixed boarding gate 4. Naturally, the clamping buckle 22 can be made of a material having a certain deformation ability under external pressure. The positioning rod 3 is a bent structure protruding downward, and the bent structure can match the boarding door arc surface 42 protruding outward on the boarding door 4, so that the boarding door 4 can be stably set on the positioning rod 3. Figure 1 In the embodiment shown, the positioning rod 3 is divided into three sections of bending structure. In the three-section bending structure, the middle section is at the lowest position, and the left section and the right section are respectively inclined. The bending degree of the bending structure needs to ensure that after the boarding door 4 is fixedly set on the positioning rod 3, the position height of the center of gravity of the whole formed by the positioning rod 3 and the boarding door 4 is lower than the position height of the line connecting the two ends of the positioning rod 3, thereby achieving that after the boarding door 4 is flipped over a certain angle, it can naturally rotate downward to the initial state with the lowest center of gravity under the action of gravity.

[0027] The side walls of the middle section of the positioning rod 3 are respectively provided with fixed seat support rods 34 extending to both sides, and the fixed seat support rods 34 are provided with lifting holes 31, which are used to realize the transfer of the aircraft boarding door flipping device and the boarding door 4 between different assembly stations by lifting. A lateral fixing seat 32 is provided above the lifting hole 31, and the lateral fixing seat 32 is threadedly matched with the threaded hole at the corresponding position on the fixed boarding door 4. At the same time, tightening the clamping knob 23 allows the clamping buckle 22 to fix the boarding door clamping end 43 of the fixed boarding door 4, thereby forming a three-point fixing structure of the clamping buckle 22 and the two lateral fixing seats 32, ensuring the fixing effect of the boarding door 4. In order to prevent scratches on the boarding door 4 during the flipping process, a flexible buffer pad 33 can be provided on the wall surface where the top surface of the positioning rod 3 contacts the fixed boarding door 4, and the flexible buffer pad 33 can be a rubber buffer pad or a foam buffer pad.

[0028] The positioning pin 15 is arranged on the support frame 12, and the positioning pin 15 can move in the horizontal direction. The adjusting disc 2 has evenly distributed fixing holes around the center of the adjusting disc 2. When the positioning pin 15 is inserted into one of the fixing holes, the adjusting disc 2 is stuck by the positioning pin 15, thereby locking the adjusting disc 2. At this time, the angular position of the positioning rod 3 is fixed, and the corresponding assembly operation can be performed.

[0029] The method for using the above-mentioned aircraft boarding door flipping device can be carried out according to the following steps: a. hoisting the boarding door 4 to the assembly station where the positioning frame is located through the lifting rod, then setting the boarding door arc surface 42 on the outside of the boarding door 4 downward, and then setting the boarding door arc surface 42 on the flexible buffer pad 33 on the top surface of the positioning rod 3; b. threading the lateral fixing seat 32 with the threaded hole at the corresponding position on the fixed boarding door 4, tightening the clamping knob 23 so that the clamping buckle 22 fixes the boarding door clamping end 43 of the fixed boarding door 4; c. rotating the adjusting disc 2 to adjust the boarding door 4 to the required rotation angle, and then setting the positioning pin 15 on the adjusting disc 2, and then the adjusting disc 2 is locked in the corresponding fixing hole on the lateral fixing seat 32, so that the rotation angle of the boarding door 4 is fixed; d. Complete the assembly operation at the required rotation angle in step c, then pull out the positioning pin 15 from the fixing hole, rotate the adjusting disc 2 to a new rotation angle and lock it again; e. After the assembly is completed at the assembly station, the aircraft boarding door flipping device and the boarding door 4 fixed on the aircraft boarding door flipping device are transferred to the next assembly station through the roller 11, or the lifting rod of the boarding door 4 is set in the lifting hole 31 of the lateral fixing seat 32, and then the aircraft boarding door flipping device and the boarding door 4 fixed on the aircraft boarding door flipping device are lifted to the next assembly station.
