Description

TECHNICAL FIELD

[0001] The application relates to the technical field of strength detection devices, and particularly relates to a strength detection device for aircraft aviation accessory production. BACKGROUND

[0002] An aircraft accessory refers to various auxiliary devices necessary for ensuring the effective, reliable and smooth work of an aircraft. The aircraft accessory includes pumps, controllers, sensors, actuators, valves and filters, etc. The aircraft accessory belongs to respective systems of the aircraft and the engine. The aircraft accessory system mainly includes a control system, an environmental control system, a hydraulic system, a fuel system, an electrical system, a power supply system and a fireproof system. In the production process of the aircraft aviation accessory, some accessories need to be subjected to strength testing, for example, ailerons, spoilers, flaps and rudders on the wings of the aircraft. In order to adapt to the sudden situation in the aviation process and the strength in daily use, the above-mentioned parts need to be subjected to strength testing. There are many simulation modes for the strength testing, one of which is bird impact testing. The bird impact testing simulates the experiment of the bird impacting the aircraft, so that the strength testing when the bird impacts the aircraft is simulated more close to the actual situation. However, in the bird impact experiment of the prior art, the artificial manual cutting or the additional chicken carcass is needed to control the actual weight, so as to weigh and simulate the weight of the bird that may be encountered, and the chicken carcass is discharged into a bag through an air cannon assembly, so as to simulate the impact of the bird with the same weight in the flight process. However, the method for simulating the bird impact by using the chicken carcass is relatively wasteful of resources, and is relatively troublesome to implement. Meanwhile, different birds need to be simulated in some regions, the sizes and weights of different birds are different, and the above-mentioned method cannot completely simulate the flight posture and size of the bird when impacting, so that the final test result may have a certain deviation.

[0031] This invention discloses a strength testing device for aircraft and aviation accessory production, relating to the technical field of strength testing devices. It includes an auxiliary simulation mechanism located on one side of a protective cover, comprising a support block. This invention utilizes an auxiliary simulation mechanism, replacing bird carcasses with gel blocks, and employs three sets of cutting components to cut the gel blocks into three-dimensional prisms. These prisms simulate the approximate size and shape of a bird in flight. Simultaneously, a pressure sensor is used for weighing, thus achieving a result that closely approximates the size, weight, and flight attitude of birds encountered in reality. Combined with an external clamping device, impact tests on accessories such as wings are conducted to more realistically simulate impacts, further improving the experimental effectiveness and efficiency of bird impact tests.

[0032] Example 2 This invention discloses a method for using a strength testing device for aircraft aerospace component manufacturing: Step 1: The third electric push rod 62, the fourth electric push rod 64, the second electric push rod 65, and the fifth electric push rod 66 are in the fully retracted state. The blades 54 in each cutting assembly 72 are not inside the cutting plate 63. The second electric slider 57 is fixedly connected to the support plate 60. The limiting plate 36 is not inside the range of the fixed plate 21. The spring 37 is in the normal state. The electromagnet 38 is not activated. The limiting plate 36 is in contact with the electromagnet 38. The user needs to input the size, weight, and other three-dimensional dimensions of the bird to be detected in the control console 12 in advance.

[0033] Step 2: The user prepares the gel block 19 to be fixed to the connecting post 28 in advance. After the gel block 19 has solidified, the user needs to move the gel block 19 onto the support block 26 and then move it to... Figure 1 The approximate location of the component is determined, and then the user activates the electromagnet 38 via the control console 12. Once activated, the electromagnet 38 repels the limiting plate 36, causing the limiting plate 36 to move towards the support block 26 under the action of the electromagnet 38, compressing the spring 37. The user manually pushes the gel block 19, arranging it in a suitable position so that one corner of the gel block 19 is in contact with the fixing plate 21 and the limiting plate 36, thus arranging the gel block 19 for subsequent work. The user then locates the clamping component connected to the outside of the protective cover 11, clamps the component to be tested, and then the invention can be activated.

[0034] Step 3: The control console 12 will drive the electromagnet 38 to de-energize, thereby causing the limiting plate 36 to reset under the action of the spring 37, no longer limiting the gel block 19, and driving the first motor 68 and the second motor 70 to start. After the first motor 68 starts, its motor shaft will drive the first connecting rod 69 to rotate outward. After the second motor 70 starts, its motor shaft will drive the second connecting rod 71 to rotate towards the center line of the support block 26, thereby making the first connecting rod 69 and the second connecting rod 71 lower than the plane of the support block 26.

[0035] Step 4: Then, the control console 12 will activate the first electric slider 67. Under the action of the control console 12, the first electric slider 67 will move to directly below the connecting post 28 on the gel block 19 closest to the direction of the launch port 61. Then, the first motor 68 and the second motor 70 will be activated again under the action of the control console 12, thereby resetting the first connecting rod 69 and the second connecting rod 71. This allows the second connecting rod 71 to enter the slot 29 on the connecting post 28 away from the direction of the gel block 19. Then, the first electric slider 67 will be activated under the action of the control console 12. After the first electric slider 67 is activated, it will move the gel block 19 a certain distance through the second connecting rod 71, the slot 29, and the connecting post 28, and then automatically stop. At this time, the gel block 19 will stop directly above the weighing platform 16.

[0036] Step 5: The control console 12 will start the fourth motor 50 and the fifth motor 53 according to the data pre-entered by the user. After the fourth motor 50 starts, its motor shaft will drive the corresponding first screw 48 to rotate, thereby causing the sliding plate 52 to move horizontally on the first limit rod 49. After the fifth motor 53 starts, its motor shaft will drive the blade 54 to rotate, thereby controlling the distance and angle between each pair of blades 54, and adjusting according to the data pre-entered by the user. Then, the control console 12 will drive the third electric push rod 62, the second electric push rod 65, and the fifth electric push rod 66 to start. After the third electric push rod 62 starts, it will begin to extend, thereby causing the cutting plate 63 to descend. As the cutting plate 63 descends, it covers the gel block 19, which is moved by the second connecting rod 71. The connecting post 28 on the gel block 19 engages with the groove on the cutting plate 63. Simultaneously, the second electric push rod 65 and the fifth electric push rod 66 extend and descend together with their corresponding cutting components 72. Then, the electric sliders in the first slide rail 43 and the second slide rail 42, along with the fourth electric push rod 64, will be activated and reset sequentially under the action of the control console 12, thereby completing the cutting of the gel block 19. This transforms the gel block 19 into a prismatic shape, similar in size to the bird being detected. The user then needs to manually remove the waste material from the cut gel block 19.

[0037] Step 6: At this time, the weighing platform 16 will begin weighing. The pressure sensor 13 will detect the weight of the gel block 19, which is supported by the second connecting rod 71 and has been cut, on the weighing platform 16. If the weight of the gel block 19 exceeds the set value, the cutting component 72 in the direction of the second electric push rod 65 will continue to start further adjustment. With the cooperation of the electric slider in the second slide rail plate 42, the gel block 19 will be further finely cut and fine-tuned. Excess gel block 19 will be continuously removed without affecting the shape of the contact surface of the gel block 19 until the weight of the gel block 19 reaches the target. When the pressure... When sensor 13 detects that the weight of the gel block 19 on the weighing platform 16 has reached the target, the pressure sensor 13 will send a signal to the control console 12. After receiving the signal from the pressure sensor 13, the control console 12 will drive the first electric slider 67 to continue to start and drive the second electric push rod 65, the fifth electric push rod 66, and the third electric push rod 62 to retract and reset for the next use, until the first electric slider 67 moves to the end of the slide rail 17 in the direction of the launch port 61. Then, the second electric slider 57 will be started by the control console 12 and move to the appropriate position.

[0038] Step 7: The motor inside the second electric slider 57 will start, driving the second screw 58 to rotate. Under the action of the second screw 58, the support plate 60 will rise. As the support plate 60 rises, it will insert into another slot 29 on the corresponding connecting post 28, thus supporting the cut gel block 19. Then, the first motor 68 and the second motor 70 will start under the action of the control console 12, causing the second connecting rod 71 to disengage. The first electric slider 67 will move to the next slot 29 to be processed under the action of the control console 12, so that the second connecting rod 71 and the first connecting rod 69 are lower than the top surface of the support block 26. Then the first electric slider 67 will be driven by the control console 12 to start the motor inside the second electric slider 57. With the cooperation of the two, the tray 60 carrying the connecting post 28 of the cut and shaped gel block 19 is inserted into the launching port 61.

[0039] Step 8: Then, under the action of the control console 12, the tray 60 is lowered and reset. The user then manually inserts the launch block 30 into the air cannon assembly 24 and completely inserts the connecting rope 31 into the air cannon assembly 24. The user then pushes the hatch 32 by holding the handle 33, so that the hatch 32 is sealed and pressed against the air cannon assembly 24. The user then activates the external air supply assembly, injecting gas into the air cannon assembly 24 through the connecting pipe 25. After calculating the energy loss and reaching the set air pressure, the launch block 30 is pushed out, causing it to slide in the pipe 27. Under the strong impact of the launch block 30, it strikes the connecting post 28 that is tightly plugged in the launch port 61, thereby transmitting the force to the connecting post 28 and the gel block 19. As a result, the gel block 19 passes through the groove 15 and strikes the aircraft aviation accessory to be tested, completing the strength test of birds striking aircraft aviation accessories during flight.

[0040] Step 9: The external clamping device re-inspects other areas by translating, rotating, or replacing parts. This device repeats the above steps to quickly cut the next gel block 19 to achieve a bird-like simulation, thereby completing rapid filling. At the same time, simulating birds with gel greatly saves economic expenses and resource waste. In addition, the size of the gel can be adjusted by cutting, making it easier to simulate the approximate posture and weight of birds during flight, which can further improve the efficiency and effect of the experiment.

[0041] In summary, this invention discloses a strength testing device for aircraft and aviation accessory production, relating to the technical field of strength testing devices. It includes an auxiliary simulation mechanism located on one side of a protective cover, comprising a support block. This invention utilizes an auxiliary simulation mechanism, replacing bird carcasses with gel blocks, and employs three sets of cutting components to cut the gel blocks into three-dimensional prisms. These prisms simulate the approximate size and shape of a bird in flight. Simultaneously, a pressure sensor is used for weighing, thus achieving a result that closely approximates the size, weight, and flight attitude of birds encountered in reality. Combined with an external clamping device, impact tests on accessories such as wings are conducted to more realistically simulate impacts, further improving the experimental effectiveness and efficiency of bird impact tests.
