[0002] An X-ray flaw detection device is a non-destructive testing equipment that uses the penetrability of X-rays to detect internal defects of materials. It usually includes a shielding cover, a conveyor belt, an X-ray source and an imaging device. In the detection of automobile pipes, the X-ray flaw detection device can detect defects such as cracks, shrinkage cavities, air holes, slag inclusions, incomplete fusion, and incomplete penetration inside the pipes.

[0003] When the automobile pipe enters the flaw detector without being flipped in time, it may affect the imaging display effect of X-ray flaw detection. Because X-ray flaw detection technology relies on the ray to penetrate the material and form a projection of the defect on the photosensitive material, and the pipe is annular and tubular. When different parts on both sides of the pipe overlap, it may cause different attenuation degrees of the ray, thereby affecting the clarity and accuracy of the imaging. Therefore, an X-ray flaw detection device for automobile pipe detection is proposed to solve the above technical problems. Content of the Utility Model

[0011] Furthermore, the width of the photosensitive plate is equal to the width of the conveyor belt to reduce the imaging dead angle.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1 to 4 , an X-ray flaw detection device for automobile pipe detection in this embodiment includes a conveyor belt 2 arranged inside the flaw detection device body 1, and a flipping assembly 3 is arranged outside the conveyor belt 2.

[0021] Embodiment 2: Please refer to Figures 2 to 4 , on the basis of Embodiment 1, the flipping assembly 3 in this embodiment includes a plurality of photosensitive plates 31 arranged outside the conveyor belt 2 for forming a projection of the defects of the automobile pipe. The plurality of photosensitive plates 31 outside the conveyor belt 2 move synchronously with the movement of the conveyor belt 2 and are ready to receive the projection after the X-ray penetrates the pipe. Two support plates 32 are fixed on the upper surfaces of the plurality of photosensitive plates 31. Rotating shafts 33 are rotatably arranged inside the two support plates 32, and adjusting gears 34 are arranged outside the two rotating shafts 33. Pipe clamps 35 are arranged at the opposite ends of the two rotating shafts 33 for clamping the automobile pipe for flaw detection flipping. Outside the flaw detection device body 1, the automobile pipe is clamped and fixed by the pipe clamp 35, and the conveyor belt 2 is started to convey the clamped automobile pipe into the flaw detection device body 1.

[0022] The flipping assembly 3 further includes two fixing plates 36. The two fixing plates 36 are both arranged inside the flaw detection device body 1 and are respectively connected to the front and rear sides of the conveyor belt 2. Three sectional toothed plates 37 are arranged on the upper surfaces of the two fixing plates 36, and the sectional toothed plates 37 are located below the adjusting gears 34 for driving the adjusting gears 34 to rotate. The sectional toothed plates 37 on the fixing plates 36 are distributed at intervals along the length direction and are ready to mesh with the adjusting gears 34. As the conveyor belt 2 moves, the sectional toothed plates 37 contact and mesh with the adjusting gears 34, driving the adjusting gears 34 to rotate, and then driving the pipe clamp 35 and the clamped automobile pipe to flip through the rotating shaft 33.

[0023] In this embodiment, stabilizing frames 38 are fixed to the opposite sides of the two support plates 32, and the inner parts of the two stabilizing frames 38 are respectively rotatably arranged with the two rotating shafts 33 through bearings, so as to maintain the stability of the clamping of the automotive pipe. The three sectional toothed plates 37 are respectively arranged at intervals along the length direction of the fixed plate 36, so as to drive the adjusting gear 34 to rotate by a fixed angle. The spaced distribution of the sectional toothed plates 37 enables the adjusting gear 34 to mesh again after a certain distance, realizing the segmented flipping of the pipe. Through the segmented flipping, the automotive pipe is gradually flipped to different angles within the flaw detection device.

[0024] A rotating hole is formed in the outer side of the support plate 32, and a bearing is arranged inside the rotating hole. The rotating shaft 33 is rotatably connected to the support plate 32 through the bearing. The width of the photosensitive plate 31 is equal to the width of the conveyor belt 2, so as to reduce the imaging dead angle.

[0025] It should be noted that the X-ray source scans the pipes at various angles. The photosensitive plate 31 captures the defect projections. The imaging device records and analyzes the projections on the photosensitive plate 31 to identify the defects inside the pipes. After a series of flips, the pipe completes a full rotation, realizing all-round flaw detection. The pipes that have completed flaw detection are unloaded from the conveyor belt 2 and conveyed to the next process or storage area. The flaw detection device is ready to receive the next batch of automotive pipes for a new round of flaw detection.

[0026] The working principle of the above embodiment is as follows:

[0027] Outside the flaw detection device body 1, the automotive pipe is clamped and fixed by the pipe clamp 35. The conveyor belt 2 is started, and the clamped automotive pipe is conveyed into the flaw detection device body 1. A plurality of photosensitive plates 31 outside the conveyor belt 2 move synchronously with the movement of the conveyor belt 2, ready to receive the projections after the X-rays penetrate the pipe. The sectional toothed plates 37 on the fixed plate 36 are arranged at intervals along the length direction, ready to mesh with the adjusting gear 34. As the conveyor belt 2 moves, the sectional toothed plate 37 contacts and meshes with the adjusting gear 34, driving the adjusting gear 34 to rotate, and then driving the pipe clamp 35 and the clamped automotive pipe to flip through the rotating shaft 33. The spaced distribution of the sectional toothed plates 37 enables the adjusting gear 34 to mesh again after a certain distance, realizing the segmented flipping of the pipe. Through the segmented flipping, the automotive pipe is gradually flipped to different angles within the flaw detection device. The X-ray source scans the pipes at various angles. The photosensitive plate 31 captures the defect projections. The imaging device records and analyzes the projections on the photosensitive plate 31 to identify the defects inside the pipes. After a series of flips, the pipe completes a full rotation, realizing all-round flaw detection. The pipes that have completed flaw detection are unloaded from the conveyor belt 2 and conveyed to the next process or storage area. The flaw detection device is ready to receive the next batch of automotive pipes for a new round of flaw detection.
