Description

Technical Field

[0001] This invention relates to the field of magnetic particle penetrant testing technology, and in particular to an integrated non-destructive testing workstation for magnetic particle penetrant testing. Background Technology

[0002] Magnetic particle testing is a method of observing defects using magnetic particles as the display medium. Also known as magnetic particle inspection or magnetic particle flaw detection, it is one of the five conventional methods of non-destructive testing. When a ferromagnetic workpiece is magnetized, the presence of discontinuities causes local distortion of the magnetic field lines on and near the workpiece surface, generating a leakage magnetic field. This field attracts fluorescent magnetic particles or magnetic suspensions applied to the workpiece surface, forming visible magnetic traces under suitable illumination. For example, under ultraviolet light, visible yellow-green magnetic traces are formed, thus revealing the location, size, shape, and severity of the discontinuities.

[0003] In critical fields such as machinery manufacturing, aerospace, and rail transportation, the detection of surface and near-surface defects in ferromagnetic material parts is crucial. These defects may originate from processes such as casting, forging, and welding. If not detected in time, they can lead to equipment failure or even catastrophic accidents. Traditional inspection processes require manual operations such as loading, spraying magnetic suspension, and observing magnetic traces, which are time-consuming and inefficient. In addition, manual observation of magnetic traces is susceptible to factors such as visual fatigue and subjective judgment, resulting in a high number of missed and false detections of wheel set cracks. Therefore, an integrated non-destructive testing workstation for magnetic particle penetration testing was designed to detect surface and near-surface defects in ferromagnetic materials. However, the following shortcomings still exist: For rectangular or other polygonal workpieces, several surfaces need to be inspected with magnetic particles. This requires flipping the workpieces for magnetization and spraying, but due to the weight of these workpieces, it is impossible to flip them quickly and stably, thus failing to improve the efficiency of magnetic particle penetration testing. Summary of the Invention

[0004] To address the technical problem that existing rectangular or other polygonal workpieces cannot stably flip and convert several surfaces for magnetization and liquid spraying, this invention proposes an integrated non-destructive testing workstation for magnetic particle penetration testing.

The drive gear is located in the middle of the track frame, and the circumference of the drive gear meshes with the first toothed plate and the second toothed plate.

[0008] Preferably, the irradiation mechanism includes a fifth pusher and a sixth pusher, and the fixed ends of the fifth and sixth pushers are rotatably mounted to the inner wall of the top of the housing. The movable end of the sixth pusher is rotatably mounted to the fixed end of the fifth pusher. An ultraviolet irradiation lamp is installed on the movable end of the fifth pusher, and an L-shaped side plate is fixedly provided on the side of the ultraviolet irradiation lamp near the housing outlet. A vision camera is obliquely installed at the bottom end of the vertical section of the L-shaped side plate. A stop is provided between the middle of the vertical section of the L-shaped side plate and the outer wall of the ultraviolet irradiation lamp. The vision camera is located at the lower end of the ultraviolet irradiation lamp.

[0009] Preferably, a drain pipe is fixedly connected to one corner of the bottom end of the support frame, a perforated plate is fixedly installed inside the upper end of the support frame, and the workpiece to be tested is placed on the top of the perforated plate.

[0013] Preferably, the outer side of the card is provided with an anti-slip and anti-wear elastic block.

[0014] The beneficial effects of this invention are as follows: 1. This invention proposes an integrated non-destructive testing workstation for magnetic particle penetration testing. A strip-shaped guide rail is located at the bottom center of the housing. A traveling frame carrying a support frame and a pre-treated workpiece moves along this guide rail into the housing for magnetic particle testing. The traveling frame stops between two positioning mechanisms. A drive motor rotates a hemispherical toothed roller, which in turn moves a transmission toothed frame towards the magnetization assembly, magnetizing the workpiece. The workpiece is then moved towards the spray mechanism, where two spray pipes spray fluorescent magnetic suspension onto its surface. The workpiece is then illuminated and photographed by an illumination mechanism for analysis. The support frame then returns to the center of the traveling frame, and the positioning mechanism... The extension of the third pusher of the mechanism allows the two clamping members to fix and hold the workpiece. The extension of the two sets of second pushers allows the clamping members to press tightly against the workpiece surface and press the two ends of the workpiece together, so that the workpiece is not unstable or even falls off during the flipping process. Then, the extension of the fourth pusher of the flipping mechanism causes the U-shaped rod to move up along the top of the housing. The two L-shaped toothed plates drive the transmission gears on the same side to rotate, so that the positioning mechanism rotates as a whole, achieving a stable and efficient flipping of the workpiece. Then, the magnetic particle inspection of the workpiece surface is performed again, so that multiple sides of the workpiece can be inspected, avoiding the tediousness of manual face changing and repeated entry into the housing.

[0015] 2. The present invention proposes an integrated non-destructive testing workstation for magnetic particle penetration testing. The workstation includes a track frame, an adjusting motor and a drive gear, a spray pipe, and a first and second toothed plate. The adjusting motor rotates the drive gear, causing the first and second toothed plates to move along the track frame. As the first and second toothed plates move, the two spray pipes move further apart. This allows the spray pipe's outlet range to be adjusted according to the size of the workpiece, ensuring that the fluorescent magnetic suspension liquid discharged from the spray pipe completely covers the workpiece surface while reducing waste of the fluorescent magnetic suspension liquid.

[0016] 3. The magnetic particle penetration testing integrated non-destructive testing workstation proposed in this invention, by having a fifth pusher and a sixth pusher, allows the ultraviolet irradiation lamp to adjust its illumination height and angle according to the size and shape of the workpiece, enabling the vision camera to capture clearer fluorescent magnetic traces, thereby recording and analyzing the defects of the workpiece. Applying statistical knowledge to analyze these defects can help improve the workpiece process. Furthermore, a stop is provided between the middle of the vertical section of the L-shaped side plate and the outer wall of the ultraviolet irradiation lamp. This stop maintains the stability of the ultraviolet irradiation lamp and the L-shaped side plate, preventing the L-shaped side plate from shaking when the ultraviolet irradiation lamp is adjusted, thus avoiding affecting the shooting accuracy of the vision camera. This helps the vision camera to quickly stabilize and enter working condition. Attached Figure Description

[0019] Reference Figure 1-8 An integrated non-destructive testing workstation for magnetic particle penetration testing includes a housing 10. A magnetization component 12 is provided at the inlet end of the housing 10 to magnetize the surface of the workpiece. A storage tank 13 is placed at the top of the housing 10 and is filled with fluorescent magnetic suspension liquid. A strip-shaped guide rail 20 is provided at the middle of the bottom end of the housing 10, and several walking seats 21 are slidably provided at the top of the strip-shaped guide rail 20. The walking seats 21 are provided with a support frame 26 at the top, so that the walking seats 21 can move and circulate along the strip-shaped guide rail 20, thereby continuously transporting the workpiece to be tested into the housing 10 for magnetic particle testing. Inside the housing 10, from inlet to outlet, there are a monitoring and control device 11, a positioning mechanism 30, a liquid spraying mechanism 50, and a trace detection mechanism 60. The magnetization component 12 is located between the positioning mechanism 30 and the monitoring and control device 11. The monitoring and control device 11 is used to monitor the shape, size, and placement status of the workpiece and the smooth operation of the walking seats 21 on the strip-shaped guide rail 20. L-shaped side seats 22 are bolted to both sides of the top of the traveling seat 21. Support members 23 are bolted to the bottom of the horizontal section of the L-shaped side seats 22 and the bottom of the traveling seat 21. The support members 23 enhance the stability of the L-shaped side seats 22, making the rotation of the hemispherical toothed roller 24 between the two L-shaped side seats 22 more stable. The hemispherical toothed roller 24 is rotatably mounted on the middle of the vertical section of the two L-shaped side seats 21 via a bearing. A drive motor 25 is fixedly mounted at the input end of the hemispherical toothed roller 24. The bottom outer wall of the support frame 26 is connected via… The transmission gear frame 27 is fixedly installed by welding, bolts or other fixing methods, and the hemispherical toothed roller 24 meshes with the upper and lower ends of the transmission gear frame 27. The hemispherical toothed roller 24 can be rotated by starting the drive motor 25, which drives the transmission gear frame 27 to move left and right in a circular motion. This allows the support frame 26 to carry the workpiece after flipping and changing its surface to the magnetization component 12 for magnetization, and then to the area below the spraying mechanism 50. The magnetic suspension liquid covers the surface of the workpiece, and the marking mechanism 60 illuminates and photographs it. Then the support frame 26 returns to the middle position of the traveling seat 21. The positioning mechanism 30 includes a cross seat 31, which is rotatably mounted to the inner wall of the housing 10 via bearings. Multiple second pushers 33 are fixedly mounted on the vertical section of the cross seat 31 by bolts. Clamping pieces 34 are fixedly mounted on the movable end of the second pushers 33 by bolts. A clamping piece is rotatably mounted in the middle of the horizontal section of the cross seat 31 via a fixed lug. Third pushers 38 are rotatably mounted on both sides of the horizontal section of the cross seat 31 via the clamping piece and the two third pushers 38. First, the third pushers 38 extend to fix the workpiece in place by the two clamping pieces. Then, the two sets of second pushers 33 extend to make the clamping pieces 34 press tightly against the surface of the workpiece. This can press the two ends of the workpiece together, so that the workpiece is not unstable or even falls off during the flipping process. It is suitable for workpieces of different shapes. Transmission gears 32 are fixedly mounted on opposite ends of the two cross seats 31, and a flipping mechanism 40 is provided between the two transmission gears 32.

[0020] In this invention, the spraying mechanism 50 includes a track frame 51, and both ends of the track frame 51 are fixedly installed to the inner walls of both ends of the housing 10 by bolts. A U-shaped seat 52 is fixedly connected to the middle of the top of the track frame 51 by bolts or welding. A first toothed plate 55 and a second toothed plate 56 are slidably installed at both ends of the track frame 51, respectively. The outer walls of the opposite ends of the first toothed plate 55 and the second toothed plate 56 are provided with slots 58. The operation of the adjusting motor 53 causes the drive gear 54 to rotate, driving the first toothed plate 55 and the second toothed plate 56 to move along the track frame 51, respectively. The two spray pipes 57 move along the first toothed plate 55 and the second toothed plate 56, respectively. The movement of plate 55 and the second toothed plate 56 moves them away from each other, thereby adjusting the liquid outlet range of the spray pipe 57 according to the size of the workpiece. This ensures that the fluorescent magnetic suspension liquid discharged from the spray pipe 57 can completely cover the surface of the workpiece, while reducing the waste of fluorescent magnetic suspension liquid. The bottom ends of the first toothed plate 55 and the second toothed plate 56 are both fixedly installed with spray pipe 57 by bolts. The bottom end of the spray pipe 57 is fixedly provided with multiple nozzles. The inlet end of the spray pipe 57 is fixedly connected with a conduit, and the two conduits are connected to the storage tank 13 by a Y-shaped pipe. The fluorescent magnetic suspension liquid inside the storage tank 13 is introduced into the spray pipe 27 through the Y-shaped pipe. An adjusting motor 53 is fixedly installed at the top center of the U-shaped seat 52 by bolts, and a drive gear 54 is fixedly installed at the output end of the adjusting motor 53. The drive gear 54 is located in the middle of the track frame 51, and the circumference of the drive gear 54 meshes with the first toothed plate 55 and the second toothed plate 56. The fluorescence magnetic trace detection mechanism 60 includes a fifth pusher 61 and a sixth pusher 62. The fixed ends of both the fifth pusher 61 and the sixth pusher 62 are rotatably mounted to the inner wall of the top of the housing 10. The movable end of the sixth pusher 62 is rotatably mounted to the fixed end of the fifth pusher 61. An ultraviolet lamp 63 is mounted on the movable end of the fifth pusher 61 via a lifting lug. With the fifth pusher 61 and the sixth pusher 62, the ultraviolet lamp 63 can adjust its illumination height and angle according to the size and shape of the workpiece, allowing the vision camera 65 to capture clearer fluorescent magnetic traces. This records and analyzes the defects in the workpiece, and then applies statistical knowledge to further analyze them. The process of the workpiece is improved, and an L-shaped side plate 64 is fixed to the side of the ultraviolet lamp 63 near the outlet of the housing 10 by bolts. A vision camera 65 is installed at an angle at the bottom of the vertical section of the L-shaped side plate 64. A stop 66 is provided between the middle of the vertical section of the L-shaped side plate 64 and the outer wall of the ultraviolet lamp 63. The vision camera 65 is located at the lower end of the ultraviolet lamp 63. The stop 66 maintains the stability of the ultraviolet lamp 63 and the L-shaped side plate 64, and prevents the L-shaped side plate 64 from shaking when the ultraviolet lamp 63 is adjusted, which would affect the shooting accuracy of the vision camera 65. This helps the vision camera 65 to quickly stabilize and start working. A drain pipe 28 is fixedly connected to one corner of the bottom of the support frame 26. A perforated plate 29 is fixedly placed inside the upper part of the support frame 26, and the workpiece to be tested is placed on the top of the perforated plate 29. The fluorescent magnetic suspension liquid slides off the surface of the workpiece and drips from the perforated plate 29 to collect inside the support frame 26. When the traveling seat 21 moves to the fluorescent magnetic suspension liquid recovery point, the drain pipe 28 automatically discharges it to avoid the fluorescent magnetic suspension liquid from spilling inside the housing 1 when the workpiece is being tested by magnetic particle inspection. The clamping component includes a barrel 35 and a clamping arm 36, which are slidably and limit-fitted together. A protective pad 37 is fixedly installed on the inner side of the horizontal section of the clamping arm 36 by bolts to prevent the clamping arm 36 from directly contacting the workpiece, thus avoiding wear on the surface of the clamping arm and the workpiece, as well as deformation of the clamping arm, and ensuring that the clamping arm 36 always maintains a stable clamping of the workpiece. An extension component 70 is provided on the inclined section of the clamping arm 36. An adjustable pitch motor 39 is fixedly installed on the outer wall of the barrel 35 by bolts, and an adjustable pitch gear 73 is fixedly installed on the output end of the adjustable pitch motor 39. The extension assembly 70 includes a U-shaped plate 71, which is fitted inside the arm cylinder 35. A rack 72 is provided inside the top of the U-shaped plate 71, and a strip groove is provided at the bottom of the U-shaped plate 71. The circumference of the adjustable gear 73 meshes with the rack 72. The adjustable motor 39 operates to rotate the adjustable gear 73, which drives the rack 73 to move. This allows the U-shaped plate 71 to move outward or inward along the arm cylinder 35 with the clamping arm 36. The clamping arm 36 can adjust its extension length according to the width of both ends of the workpiece to ensure that the clamping component can stably clamp the workpiece. The flipping mechanism 40 includes an L-shaped toothed plate 41, and the vertical section of the L-shaped toothed plate 41 meshes with the transmission gear 32. A U-shaped rod 42 is fixedly connected between the top ends of the horizontal sections of the two L-shaped toothed plates 41. A fourth pusher 43 is rotatably installed on the top end of the housing 10, and the U-shaped rod 42 is slidably sleeved with the top end of the housing 10. The movable end of the fourth pusher 43 is sleeved in the middle with the U-shaped rod 42. By extending the fourth pusher 43, the U-shaped rod 42 can be moved upward along the top end of the housing 10, and then the two L-shaped toothed plates 41 will rotate with the transmission gear 32 on the same side, so that the positioning mechanism 30 rotates as a whole, achieving the effect of flipping the workpiece. The outer side of the clip 34 is provided with anti-slip and anti-wear elastic blocks, which not only avoids wear caused by direct contact between the clip 34 and the workpiece, but also makes the clip 34 more secure and even more in line with the surface of the workpiece.

[0021] Working principle: A strip guide rail 20 is provided at the bottom center of the housing 10. The traveling seat 21, carrying the support frame 26 and the pre-treated workpiece, moves along the strip guide rail 20 into the housing 1 for magnetic particle inspection. The traveling seat 21 stops between two positioning mechanisms 30. The drive motor 25 works to rotate the hemispherical toothed roller 24, which drives the transmission toothed frame 27 to move towards the magnetization component 12. The workpiece is magnetized and then moves to the area below the spraying mechanism 50. Fluorescent magnetic suspension is sprayed by two spray pipes 57. The fluorescent magnetic suspension covers the surface of the workpiece. The inspection mechanism 60 illuminates and photographs the workpiece and analyzes the results. Then, the support frame 26 returns to the center position of the traveling seat 21. Finally, the third push of the positioning mechanism 30... The extension of component 38 allows two clamping components to fix and hold the workpiece in place. The extension of two sets of second pushers 33 allows the clamping component 34 to press tightly against the workpiece surface, pressing the two ends of the workpiece together. This prevents the workpiece from becoming unstable or even falling off during the flipping process. Then, the extension of the fourth pusher 43 of the flipping mechanism 40 allows the U-shaped rod 42 to move upward along the top of the housing 10. The two L-shaped toothed plates 41 rotate the transmission gears 32 on the same side, causing the positioning mechanism 30 to rotate as a whole. This achieves a stable and efficient flipping of the workpiece. The workpiece surface is then subjected to magnetic particle testing, allowing multiple sides of the workpiece to be tested. This avoids the tediousness of manual face changing and the need for repeated entry into the housing 1. The spraying mechanism 50 includes a track frame 51, an adjusting motor 53, a drive gear 54, a spray pipe 57, a first toothed plate 55, and a second toothed plate 56. The adjusting motor 53 rotates the drive gear 54, causing the first toothed plate 55 and the second toothed plate 56 to move along the track frame 51 respectively. The two spray pipes 57 move away from each other as the first toothed plate 55 and the second toothed plate 56 move. This allows the spraying range of the spray pipes 57 to be adjusted according to the size of the workpiece, ensuring that the fluorescent magnetic suspension liquid discharged by the spray pipes 57 can completely cover the surface of the workpiece, while reducing the waste of the fluorescent magnetic suspension liquid. With the fifth pusher 61 and the sixth pusher 62, the UV lamp 63 can adjust its illumination height and angle according to the size and shape of the workpiece, so that the vision camera 65 can capture clearer fluorescent magnetic traces, thereby recording and analyzing the defects of the workpiece. Then, by applying statistical knowledge to analyze them, it can help improve the workpiece process. In addition, a stop 66 is provided between the middle of the vertical section of the L-shaped side plate 64 and the outer wall of the UV lamp 63. The stop 66 maintains the stability of the UV lamp 63 and the L-shaped side plate 64, and prevents the L-shaped side plate 64 from shaking when the UV lamp 63 is adjusted, which would affect the shooting accuracy of the vision camera 65. This helps the vision camera 65 to quickly stabilize and start working.
