[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 6 As shown, this utility model provides an automated intelligent X-ray inspection machine for non-destructive testing of heavy industrial castings, including a chassis 1, with an inlet on the front of the chassis 1. In one embodiment, it also includes a trolley docking device 2 connected to the inlet, a loading trolley 3 arranged on the trolley docking device 2, a stage device 4 installed in the chassis 1, and an X-ray inspection device 5 installed in the chassis 1 and arranged on one side of the stage device 4. The stage device 4 includes an X-axis slide rail 41 arranged in the chassis 1, an X-axis slide plate 42 slidably arranged on the X-axis slide rail 41, and an X-axis translation mechanism for driving the X-axis slide plate 42 to move. A Y-axis guide rail 43 is also installed on each of the top two sides of the X-axis slide plate 42 along its length direction.

[0025] In this embodiment, a protective double lead door is also installed at the inlet of the chassis 1. The inlet of the chassis 1 is the channel for the product to enter the testing machine. The X-axis translation mechanism can drive the X-axis slide plate 42 to move so that the Y-axis guide rail 43 can dock with the trolley docking device 2. The trolley docking device 2 can transfer the loading trolley 3 carrying the product to the Y-axis guide rail 43 (then the lead door is closed to prevent X-ray leakage). The loading trolley 3 can move the product to the X-ray detection device 5. The X-ray detection device 5 can acquire its internal structure image, thereby realizing non-destructive testing of heavy industrial castings.

[0026] Preferably, in this embodiment, the X-axis translation mechanism includes an X-axis rack 44 installed in the housing 1 along the length of the X-axis slide rail 41, a first mounting base 45 connected to one side of the X-axis slide plate 42, an X-axis translation motor 46 mounted on the first mounting base 45, an X-axis reducer connected to the X-axis translation motor 46, and an X-axis gear 47 connected to the X-axis reducer; the X-axis gear 47 meshes with the X-axis rack 44. When the X-axis translation motor 46 starts, it can be reduced in speed by the X-axis reducer and drive the X-axis gear 47 to rotate. Since the X-axis gear 47 is meshed with the X-axis rack 44, it will drive the X-axis slide plate 42 to move along the X-axis slide rail 41, thereby adjusting the position of the product in the X-axis direction for inspection. At the same time, a Y-axis limiting block 48 is installed on the top of the X-axis slide plate 42 near the X-ray inspection device 5. An X-axis limiting block 49 is also installed on one side of the X-axis slide plate 42 inside the housing 1. The Y-axis limiting block 48 is used to limit the movement of the loading trolley 3, and the X-axis limiting block 49 is used to limit the movement of the X-axis slide plate 42, thereby improving the safety of equipment operation.

[0028] The Z-axis lifting mechanism 52 can be driven by a linear module or a motor with a synchronous belt, which can drive the Z-axis lifting frame 53 to move up and down, thereby adjusting the height of the X-ray emitter 57 and the X-ray receiver 58. A swing plate 54 is rotatably connected to one side of the Z-axis lifting frame 53. A swing drive mechanism 55 is mounted on the Z-axis lifting frame 53 and connected to the swing plate 54, driving the swing plate 54 to rotate, allowing the X-ray emitter 57 and the X-ray receiver 58 to swing within a certain angle range, thus acquiring X-ray images of the product at different angles. The swing plate 54 can be connected to the Z-axis lifting frame 53 via a hollow rotating platform. 3. The swing drive mechanism 55 can adopt a motor gear transmission method, which is not limited (in one embodiment, a bearing connection method can be adopted, with the inner ring of the bearing connected to the Z-axis lifting frame 53 and the outer ring of the bearing connected to the swing plate 54. The swing drive mechanism 55 includes a large gear mounted on the bearing, a motor mounted on the Z-axis lifting frame 53, and a small gear connected to the motor, which meshes with the large gear).

[0031] During loading, the casting can be transported to the rotary table 34 using a convenient method such as a robot, cantilever crane, or gantry crane. Then, the first motor 321 of the travel drive mechanism 32 drives the first drive wheel 323 to rotate via the first reducer 322. The first drive wheel 323 drives the first driven wheel 324 to rotate via the first transmission belt 325. The first driven wheel 324 is mounted on the transmission shaft, thereby driving the transmission shaft to rotate. The transmission shaft drives the first synchronous wheel 316 to rotate via the first synchronous belt, which in turn drives the rotating shaft 312 to rotate. The traveling roller 313 rotates accordingly, realizing the movement of the trolley. The trolley can move into the inspection machine, and then the lead door closes. The second motor 331 of the loading rotary mechanism 33 drives the first gear 333 to rotate via the second reducer 332. The first gear 333 meshes with the second gear 334, which in turn drives the rotary table 34 to rotate, thereby rotating the casting so that it can be inspected by the X-ray inspection device 5.

[0032] Preferably, in this embodiment, a position sensor 335 is installed at one end of the vehicle body 31, and a sensing plate 336 for use with the position sensor 335 (which may be a U-shaped photoelectric sensor) is also installed at the bottom of the rotating disk 34.
