Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0041] See also Figure 1-Figure 5, an X-ray nondestructive testing device for aircraft wing blades, comprising: an operating table 1; a supporting device 4, used for supporting and conveying the wing blades, the supporting device 4 being arranged on the operating table 1; a detector 2 being installed on the operating table 1, the supporting device 4 comprising a motor 41, the motor 41 being installed at the bottom of the operating table 1, the output end of the motor 41 being connected with a rotating wheel 42, the rotating wheel 42 being rotatably connected with the inner wall of the operating table 1, a first lever 43 being installed on the rotating wheel 42, a rotating shaft 45 being rotatably installed on the operating table 1, an arc-shaped groove ring 44 being installed on the outer wall of the rotating shaft 45, four slide grooves being opened on the arc-shaped groove ring 44, the four slide grooves being in a circular array, the four slide grooves of the arc-shaped groove ring 44 being all located on the motion trajectory of the first lever 43 A storage platform 46 is installed on the top of the rotating shaft 45, and four sliding blocks 47 are installed on the storage platform 46. The motor 41 is started, and the motor 41 drives the rotating wheel 42 to rotate, and the rotating wheel 42 drives the first lever 43 to rotate. The first lever 43 will contact one of the sliding grooves on the arc groove ring 44 during the rotation process. When the first lever 43 contacts the sliding groove, the first lever 43 will drive the arc groove ring 44 to rotate through the sliding groove. Each rotation of the first lever 43 will drive the arc groove ring 44 to rotate ninety degrees. When the arc groove ring 44 rotates, it drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the storage platform 46 to rotate; the feeding assembly 3 is used to place and transport the wing blades to be tested;The feeding assembly 3 is arranged on the operating table 1, and the feeding assembly 3 includes a bracket 31, the bracket 31 is installed on the operating table 1, a material trough 32 is installed on the bracket 31, and a material discharge port is arranged on the material trough 32. Usually, the thickness of one end of the wing blade is greater than that of the other end. The staff will place the thicker end of the wing blade to be tested upward in the material trough 32 on the bracket 31 in sequence. The inner wall of the material trough 32 is hinged with a top plate 33, and a top rod 34 is slidably installed on the bracket 31. There is an inclined rod 35, the bottom surface of the top plate 33 is slidably connected to the top of the top rod 34, the inclined rod 35 is connected to the bracket 31 through a spring, and the end of the inclined rod 35 away from the bracket 31 is slidably connected to the outer wall of the arc groove ring 44, and an inclined surface is provided on the inclined rod 35. The inclined surface of the inclined rod 35 is slidably connected to the bottom of the top rod 34. When the arc groove ring 44 rotates, the arc groove ring 44 cooperates with the inclined rod 35 and the spring on the inclined rod 35, so that the arc groove ring 44 rotates with The movable inclined plane rod 35 performs horizontal reciprocating motion, and the inclined plane rod 35 drives the push rod 34 to perform vertical reciprocating motion during the reciprocating motion. The push rod 34 will push up one end of the top plate 33 when moving upward. When the notch on the storage platform 46 rotates to below the discharge port of the material trough 32, the wing blade falls into the notch by gravity, and the thicker end of the wing blade rests on the notch of the storage platform 46, so that the storage platform 46 lifts the wing blade, and the thinner end of the wing blade is downward and suspended in the air. When the notch on the storage platform 46 is not located below the discharge port, the wing blade in the trough 32 cannot fall due to the obstruction of the sliding block 47. Since the trough 32 is arranged in an oblique shape, after the wing blade close to the storage platform 46 falls, the next wing blade slides to the position of the discharge port by its own gravity. After the top plate 33 is lifted up, it will promote the wing blade inside the trough 32 to slide toward the lower discharge port. The storage platform 46 rotates to transport the wing blade to the front of the detector 2 for detection.

[0042] By setting the supporting device 4, the storage table 46 can gradually transport the wing blade to the front of the detector 2 for detection by rotating ninety degrees each time. Since only one wing blade is detected at a time, and the wing blade is suspended in the air because one end is supported by the storage table 46, the probability of the wing blade being blocked during detection can be reduced, avoiding the shadow, scattering or deviation of X-rays during the detection process, thereby improving the accuracy of the detection result; by setting the feeding component 3, the push rod 34 can repeatedly lift the top plate 33 during the rotation of the storage table 46. After the top plate 33 is lifted, it can promote the wing blade inside the material trough 32 to slide forward, avoiding the poor sliding property of the wing blade when detecting the wing blade with a large surface friction. Blockage.

[0043] For further information, see Figure 4, an adjusting device 5 is used to adjust the supporting device 4; the adjusting device 5 is arranged on the supporting device 4, and the adjusting device 5 comprises a handwheel shaft 51, which is rotatably mounted on the inner wall of the storage platform 46, and four paddles 52 are mounted on the handwheel shaft 51, and four sliding blocks 53 are slidably mounted on the inner wall of the storage platform 46, and the sliding blocks 53 are slidably connected with the paddles 52, and four fixed blocks 54 are mounted on the inner wall of the storage platform 46, and the four fixed blocks 54 are respectively connected to the four sliding blocks 53 through springs. When a wing blade with a smaller thickness is detected, the staff rotates the handwheel shaft 51, and the handwheel shaft 51 drives the four paddles 52 to rotate. The four paddles 52 cooperate with the four fixed blocks 54 and the springs, so that the four paddles 52 can drive the sliding blocks 53 to move horizontally when moving. When the sliding blocks 53 move toward the notch direction close to the storage platform 46, the notch size of the storage platform 46 can be reduced, so that the storage platform 46 can hold up the wing blade with a smaller thickness.

[0044] By setting the adjustment device 5, the staff can adjust the position of the sliding block 53 by rotating the handwheel shaft 51, so as to adjust the size of the notch on the storage platform 46, so that the storage platform 46 can hold wing blades of different thicknesses, thereby improving the application range of the storage platform 46.

A curved block 63 is slidably installed on the operating table 1, and the curved block 63 is connected to the spring piece 62. A mounting frame 65 is installed on the top surface of the curved block 63, and two sponges 66 are installed on the mounting frame 65. A second lever 64 is installed on the rotating wheel 42, and the curved block 63 is located on the motion track of the second lever 64. When the rotating wheel 42 rotates, the rotating wheel 42 drives the second lever 64 to rotate, and the second lever 66 Each rotation can contact the arc block 63 and drive the arc block 63 to move in the direction close to the fixed seat 61. When the second lever 64 is not in contact with the arc block 63, the arc block 63 is reset by the elastic force of the spring sheet 62. When the arc block 63 moves, it drives the two sponges 66 to move synchronously through the mounting frame 65, so that when the storage table 46 rotates once, the two sponges 66 can first move in the direction close to the fixed seat 61. When the storage table 46 rotates more than 45 degrees this time, the two sponges 66 move in the direction close to the storage table 46.

[0047] By setting the cleaning device 6, the two sponges 66 can reciprocate with the rotation of the storage table 46. The two sponges 66 clean the surface of the wing blades in transportation through reciprocating motion to prevent dirt from adhering to the surface of the wing blades and affecting the detection.

[0048] In this embodiment, the discharging assembly 7 is used to remove the wing blades from the supporting device 4.

[0049] See also Figure 7 The discharging assembly 7 is arranged on the operating table 1, and the discharging assembly 7 includes a base 71, on which an inclined frame 72 is installed, and the inclined frame 72 is located below the storage table 46. Two guide rods 73 are installed on the base 71. When the wing blade is detected, the storage table 46 transports the wing blade to the inclined frame 72 on the base 71. When the wing blade contacts the inclined frame 72, the wing blade moves along the inclined surface of the inclined frame 72 in the direction away from the rotating shaft 45. When the wing blade is out of contact with the storage table 46, the wing blade will move between the two guide rods 73 and be lifted by the two guide rods 73. The wing blade slides along the two guide rods 73 to the next process. The two guide rods 73 can be adjusted by the staff to adapt to wing blades of different widths. Example

[0050] An X-ray nondestructive testing method for an aircraft wing blade comprises any one of the above-mentioned X-ray nondestructive testing devices for an aircraft wing blade, and further comprises the following steps:

[0051] Step 1: placing the wing blade to be inspected in the trough 32;

[0052] Step 2: Start the supporting device 4 and the detector 2, and transport the wing blade to the front of the detector 2 for detection by rotating the storage platform 46;

[0053] Step 3: The staff observes and records the test results. When unqualified wing blades appear, the staff picks out the wing blades and transports them to the corresponding process;

[0054] Step 4: The wing blades that pass the inspection are transported to the next process through the discharge assembly 7.

[0055] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0056] Working principle: usually, the thickness of one end of the wing blade is greater than the other end. The staff will place the thicker end of the wing blade to be tested upward in the material trough 32 on the bracket 31 in turn, and start the motor 41. The motor 41 drives the rotating wheel 42 to rotate, and the rotating wheel 42 drives the first lever 43 to rotate. During the rotation process, the first lever 43 will contact one of the slide grooves on the arc groove ring 44. When the first lever 43 contacts the slide groove, the first lever 43 will drive the arc groove ring 44 to rotate through the slide groove. Each rotation of the first lever 43 will drive the arc groove ring 44 to rotate ninety degrees. When the arc groove ring 44 rotates, it drives the rotating shaft 45 to rotate. The rotating shaft 45 drives the storage platform 46 to rotate. When the notch on the storage platform 46 rotates to below the discharge port of the material trough 32, the wing blade falls into the notch by gravity. The thicker end of the wing blade rests on the notch of the storage platform 46, so that the storage platform 46 lifts the wing blade, and the thinner end of the wing blade is downward and suspended in the air. When the notch on the storage platform 46 is not located below the discharge port, the wing blade in the material trough 32 cannot fall due to the obstruction of the sliding surface block 47. Since the material trough 32 is arranged in an oblique shape, after the wing blade close to the storage platform 46 falls, the next wing blade slides to the position of the discharge port by its own gravity, and the storage platform 46 By rotating, the wing blade is transported to the front of the detector 2 for detection. By setting the supporting device 4, the storage platform 46 is gradually transported to the front of the detector 2 for detection by rotating 90 degrees each time. Since only one wing blade is detected at a time, and the wing blade is suspended in the air because one end is supported by the storage platform 46, the probability of the wing blade being blocked during detection can be reduced, and the X-rays are prevented from being shadowed, scattered or offset during the detection process, thereby improving the accuracy of the detection result. When detecting a wing blade with a smaller thickness, the staff rotates the handwheel shaft 51, and the handwheel shaft 51 drives the four paddles 5 2 rotates, the four paddles 52 cooperate with the four fixed blocks 54 and the spring, so that the four paddles 52 can drive the sliding block 53 to move in the horizontal direction when moving. When the sliding block 53 moves toward the notch direction close to the storage platform 46, the notch size of the storage platform 46 can be reduced, so that the storage platform 46 can hold up the wing blades with smaller thickness. Through the setting of the adjustment device 5, the staff can adjust the position of the sliding block 53 by rotating the handwheel shaft 51, thereby realizing the adjustment of the notch size on the storage platform 46, so that the storage platform 46 can hold up the wing blades with different thicknesses, thereby improving the application range of the storage platform 46;As the arc groove ring 44 rotates, the arc groove ring 44 cooperates with the inclined rod 35 and the spring on the inclined rod 35, so that when the arc groove ring 44 rotates, it drives the inclined rod 35 to perform horizontal reciprocating motion. During the reciprocating motion, the inclined rod 35 drives the push rod 34 to perform vertical reciprocating motion. When the push rod 34 moves upward, it will push up one end of the top plate 33. After the top plate 33 is pushed up, it will promote the wing blades inside the material trough 32 to slide toward the lower material port. Through the arrangement of the feeding component 3, the push rod 34 can repeatedly push up the top plate 33 during the rotation of the storage platform 46. After 33 is lifted up, it can promote the wing blades inside the material trough 32 to slide forward, avoiding the poor sliding property of the wing blades and causing material blockage when detecting the wing blades with large surface friction; when the rotating wheel 42 rotates, the rotating wheel 42 drives the second lever 64 to rotate, and each rotation of the second lever 64 can contact the arc block 63 and drive the arc block 63 to move in the direction close to the fixed seat 61. When the second lever 64 does not contact the arc block 63, the arc block 63 is reset by the elastic force of the spring piece 62, and the arc block 63 drives the two sponges 66 to move through the mounting bracket 65 during movement. 6 synchronous movement, so that when the storage platform 46 rotates once, the two sponges 66 can first move in the direction close to the fixed seat 61, when the storage platform 46 rotates more than forty-five degrees this time, the two sponges 66 move in the direction close to the storage platform 46, so that the two sponges 66 clean the wing blades being transported on the storage platform 46 through reciprocating motion, and the two sponges 66 can reciprocate with the rotation of the storage platform 46 through the setting of the cleaning device 6. The two sponges 66 clean the surface of the wing blades being transported through the reciprocating motion, avoiding To prevent dirt from adhering to the surface of the wing blade and affecting the inspection; when the wing blade is inspected, the storage platform 46 transports the wing blade to the inclined frame 72 on the base 71. When the wing blade contacts the inclined frame 72, the wing blade moves along the inclined surface of the inclined frame 72 in the direction away from the rotating shaft 45. When the wing blade is out of contact with the storage platform 46, the wing blade moves between the two guide rods 73 and is lifted by the two guide rods 73. The wing blade slides along the two guide rods 73 to the next process. The two guide rods 73 can be adjusted by the staff to adapt to wing blades of different widths. ;
