The bottom of the connecting ring 51 is rotatably installed with a rotating ring 52, and the bottom of the rotating ring 52 is rotatably connected with a fixed ring 53, and the fixed ring 53 is installed on the mounting frame 1. The outer wall of the rotating ring 52 is installed with a first lever 54, and the end of the rotating shaft 22 away from the motor 21 is connected to a rotating wheel 55, and the surface of the rotating wheel 55 is connected to a sliding groove rod 56 through a roller sliding, and the sliding groove rod 56 is connected to a fork frame 57, and the fork frame 57 The rotating wheel 55 is slidably connected with the first lever 54. When the rotating wheel 55 rotates, the sliding groove rod 56 is driven to perform horizontal reciprocating motion through the sliding groove rod 58. The sliding groove rod 56 drives the fork frame 57 to perform horizontal reciprocating motion. The fork frame 57 drives the rotating ring 52 to reciprocate through the first lever 54. Four sliding blocks 58 are slidably installed on the fixed ring 53. The four sliding blocks 58 are in a circular array. The sliding blocks 58 are slidably connected with adjacent sliding blocks 58. The four sliding blocks 58 are respectively meshed with four gears 59. The four gears 59 are rotatably installed on the fixed ring 53. An inner tooth ring 510 is installed on the inner wall of the rotating ring 52. The four gears 59 are all meshed with the inner tooth ring 510.

After entering the hopper 3, the parts fall onto the four sliders 58 through the connecting ring 51. When the four sliders 58 are opened, the parts fall onto the conveyor belt 23 below through the openings between the sliders 58. Since the four sliders 58 will be closed immediately after opening, the subsequent parts will be blocked from falling. When the four sliders 58 are opened once, only one part will fall onto the conveyor belt 23, and the parts will be transported to the bottom of the detector 4 by the conveyor belt.

In addition, since the parts pass through the detector 4 one by one, when a part has a problem, the staff can take out the corresponding part in time, avoiding the simultaneous detection of multiple parts causing the staff to be unable to find the problematic parts in a short time, thereby affecting the work efficiency.

[0051] In this embodiment, the anti-blocking device 6 is used to prevent material blockage.

[0052] See also Figure 6 The anti-blocking device 6 is arranged inside the hopper 3, and the anti-blocking device 6 includes a guide frame 61, which is slidably installed on the inner wall of the hopper 3, and is connected with a short rod 62. A second lever 64 is installed on the outer wall of the rotating ring 52. A lever 63 is rotatably installed on the hopper 3, and the bottom of the lever 63 is slidably connected with the second lever 64, and the top of the lever 63 is slidably connected with the short rod 62. When the rotating ring 52 rotates back and forth, the rotating ring 52 drives the second lever 64 to swing back and forth, and the second lever 64 drives the short rod 62 to perform horizontal reciprocating motion through the lever 63, and the short rod 62 drives the guide frame 61 to perform horizontal reciprocating motion. The guide frame 61 promotes the falling of parts inside the hopper 3 through horizontal reciprocating motion.

The push rod 71 is connected to the slide rod 56. A connecting rod 72 is hinged on the push rod 71. Two brackets 73 are slidably installed on the mounting frame 1, one of which is hinged to the end of the connecting rod 72 away from the push rod 71. When the slide rod 56 performs horizontal reciprocating motion, the slide rod 56 drives the push rod 71 to perform horizontal reciprocating motion. The push rod 71 drives one of the brackets 73 to perform horizontal reciprocating motion through the connecting rod 72. The bottom of the two brackets 73 are respectively hinged to two force transmission rods 74. A rotating rod 75 is rotatably installed at the bottom of the mounting frame 1. Since the two brackets 73 are respectively connected to the rotating rod 75 through two force transmission rods 74, the two brackets 73 can perform synchronous reverse motion. The ends of the two force transmission rods 74 away from the brackets 73 are respectively hinged to the two ends of the rotating rod 75 Two mounting seats 76 are respectively installed on the two brackets 73. When one of the brackets 73 moves in the direction close to the conveyor belt 23, the other bracket 73 is driven by the two force transmission rods 74 and the rotating rod 75 and moves in the direction close to the conveyor belt 23 at the same time. The two brackets 73 drive eight guide wheels 77 to move in the direction close to the conveyor belt 23 through the two mounting seats 76. When one of the brackets 73 moves in the direction away from the conveyor belt 23, the other bracket 73 moves in the direction away from the conveyor belt 23 at the same time. Four guide wheels 77 are installed on the mounting seat 76 through a torsion spring. The two brackets 73 drive the eight guide wheels 77 to move in the direction away from the conveyor belt 23 through the two mounting seats 76. The eight guide wheels 77 will continuously contact the parts on the conveyor belt 23 during the movement. When the guide wheels 77 contact the parts, the eight guide wheels 77 will center the parts through cooperation.

A spring piece 83 is installed at the bottom of the fixed plate 81, and a resistance rod 84 is installed on one of the force transmission rods 74. The spring piece 83 is located on the movement trajectory of the resistance rod 84. When the force transmission rod 74 equipped with the resistance rod 84 moves, the force transmission rod 74 drives the resistance rod 84 to reciprocate. The resistance rod 84 will repeatedly push the spring piece 83 during the reciprocating motion. After being pushed, the spring piece 83 will drive the fixed plate 81 to vibrate. When the fixed plate 81 vibrates, it drives the cleaning brush 82 to vibrate. During the vibration process, the cleaning brush 82 cleans the moving conveyor belt 23.

[0059] In this embodiment, the cleaning device 8 is provided so that the cleaning brush 82 can clean the moving conveyor belt 23, thereby preventing the conveyor belt 23 from being adhered to a large amount of debris and dust on its surface after long-term use. When the parts are conveyed, the dust and debris are contaminated on the parts, which affects the subsequent inspection. The cleaning brush 82 can shake off the debris attached during the cleaning process through vibration, thereby improving its own cleaning effect.

[0060] Example 2

[0061] An automated X-ray nondestructive testing method for aviation parts, comprising any one of the automated X-ray nondestructive testing devices for aviation parts described above, and further comprising the following steps:

[0062] Step 1: Start the detector 4 and the conveying assembly 2;

[0063] Step 2: Put the parts to be tested into the hopper 3 in batches;

[0064] Step 3: The parts are placed one by one on the conveyor belt 23 by the material distribution device 5, and are transported to the bottom of the detector 4 by the conveyor belt 23;

[0065] Step 4: The detector 4 detects the parts passing below it, and the staff pays attention to the data of the detector 4. When unqualified parts appear, the staff can take the parts out and send them to the corresponding process;

[0066] Step 5: After the qualified parts pass through the detector 4, they are transported to the next process by the conveyor belt 23.

[0067] 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.

After entering the hopper 3, the parts will fall onto the four sliders 58 through the connecting ring 51. When the four sliders 58 are opened, the parts will fall onto the conveyor belt 23 below through the openings between the sliders 58. Since the four sliders 58 will be closed immediately after opening, the subsequent parts will be blocked, so that only one part will fall onto the conveyor belt 23 when the four sliders 58 are opened once. The parts are transported by the conveyor belt to the bottom of the detector 4, and the detector 4 detects the parts passing below. When a part has a problem, the staff will handle it in time. Through the setting of the material dividing device 5, the four slide blocks 58 are matched to place the parts one by one on the conveyor belt 23. The parts are conveyed to the bottom of the detector 4 through the conveyor belt 23 for detection. The detection of a single part can make the X-ray imaging clearer, avoid the simultaneous detection of multiple parts, which may cause some parts to be blocked by other parts, thereby affecting the detection. In addition, since the parts pass through the detector 4 one by one, when a part has a problem, the staff can take out the corresponding part in time, avoiding the simultaneous detection of multiple parts, which may cause the staff to be unable to find the problematic parts in a short time. Affects work efficiency; when the rotating ring 52 rotates back and forth, the rotating ring 52 drives the second lever 64 to swing back and forth, and the second lever 64 drives the short rod 62 to perform horizontal reciprocating motion through the lever 63, and the short rod 62 drives the guide rack 61 to perform horizontal reciprocating motion. The guide rack 61 promotes the falling of parts inside the hopper 3 through horizontal reciprocating motion. Through the setting of the anti-blocking device 6, the guide rack 61 can drive the parts inside the hopper 3 to fall in an orderly manner along the guide rack 61 through its own shaking, thereby avoiding the irregular-shaped parts from getting stuck with each other in the hopper 3 when detecting irregular-shaped parts, thereby causing blockage.

[0069] When the slide slot rod 56 performs horizontal reciprocating motion, the slide slot rod 56 drives the push rod 71 to perform horizontal reciprocating motion, and the push rod 71 drives one of the brackets 73 to perform horizontal reciprocating motion through the connecting rod 72. Since the two brackets 73 are connected to the rotating rod 75 through two force transmission rods 74, respectively, the two brackets 73 can perform synchronous reverse motion. Therefore, when one of the brackets 73 moves in the direction close to the conveyor belt 23, the other bracket 73 is driven by the two force transmission rods 74 and the rotating rod 75 and moves in the direction close to the conveyor belt 23 at the same time. The two brackets 73 drive the eight guide wheels 77 to move in the direction close to the conveyor belt 23 through the two mounting seats 76. When one of the brackets 73 moves in the direction away from the conveyor belt 23, the other bracket 73 moves in the direction away from the conveyor belt 23 at the same time. The two brackets 73 drive the eight guide wheels 77 to move in the direction away from the conveyor belt 23 through the two mounting seats 76. The eight guide wheels 77 will continuously contact the parts on the conveyor belt 23 during the movement. When the guide wheels 77 contact the parts, the eight guide wheels 77 are connected to the The parts are centered and aligned. By setting the centering device 7, the eight guide wheels 77 can center and align the parts transported on the conveyor belt 23, thereby preventing the parts from being skewed after falling on the conveyor belt 23, which will affect the detection when the parts move below the detector 4; when the force transmission rod 74 equipped with the resistance rod 84 moves, the force transmission rod 74 drives the resistance rod 84 to reciprocate. The resistance rod 84 will repeatedly push the spring piece 83 during the reciprocating motion, and the spring piece 83 will drive the fixing plate after being pushed 81 vibrates, and the fixed plate 81 drives the cleaning brush 82 to vibrate when vibrating. The cleaning brush 82 cleans the moving conveyor belt 23 during the vibration. Through the setting of the cleaning device 8, the cleaning brush 82 can clean the moving conveyor belt 23 to prevent the conveyor belt 23 from having a lot of debris and dust attached to its surface after long-term use. When conveying parts, dust and debris are contaminated on the parts, which affects subsequent inspection. The cleaning brush 82 can shake off the debris attached during the cleaning process through vibration, thereby improving its own cleaning effect.
