Description

Technical Field

[0001] This utility model belongs to the field of weld inspection technology, and specifically relates to an automatic weld inspection line. Background Technology

[0002] Welded pipe is a type of pipe manufactured using precision resistance welding (ERW) technology, widely used in various fields of manufacturing. After the welding process, the microstructure consists of ferrite and pearlite, and may even contain lower bainite. The microstructure may be affected by the cooling rate, resulting in coarse grains and a decrease in mechanical properties. Normalizing is required to homogenize the weld microstructure and obtain a finer microstructure, ensuring that the affected area meets its mechanical properties. However, normalizing does not homogenize the ferrite and pearlite microstructure and grain structure of the entire steel pipe, leading to unstable mechanical properties in the transition area and thus affecting product quality.

[0003] Therefore, weld inspection is required before production to prevent the use of bosses in the weld area, thereby avoiding surface cracking caused by bosses. Utility Model Content

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1

[0028] refer to Figures 1 to 7This embodiment describes an automated weld inspection line, including a mounting platform 1. The mounting platform 1 is equipped with a feeding assembly 2, a moving assembly 3, and an inspection assembly 5. A rotating fixing assembly 4 is mounted on the output end of the moving assembly 3. The rotating fixing assembly 4 fixes the seamless tube and drives it to rotate. The seamless tube is parallel to the X-axis. The moving assembly 3 drives the rotating fixing assembly 4 to move along the X-axis, Y-axis, and Z-axis. The moving assembly 3 includes an X-axis linear assembly, a Y-axis linear assembly, and a Z-axis linear assembly. The Z-axis linear assembly is mounted on the output end of the Y-axis linear assembly, the Y-axis linear assembly is mounted on the output end of the X-axis linear assembly, and the rotating fixing assembly 4 is mounted on the output end of the Z-axis linear assembly. The rotating fixing assembly 4 includes a mounting box 2 mounted on the output end of the Z-axis linear assembly. The mounting box 42 is equipped with a fixing assembly and a rotating assembly, with the fixing assembly mounted on the output end of the rotating assembly.

[0029] It also includes a controller, and the feeding component 2, moving component 3, rotating and fixing component 4 and detection component 5 are all electrically connected to the controller.

[0030] Preferably, the controller includes a PLC controller.

[0031] The X-axis linear assembly drives the Y-axis linear assembly to move along the X-axis, the Y-axis linear assembly drives the Z-axis linear assembly to move along the Y-axis, and the Z-axis linear assembly drives the rotating fixed assembly 4 to move along the Z-axis. This continues until the rotating fixed assembly 4 moves to one end of the feeding assembly 2. The seamless tube to be inspected is then pushed and installed onto the fixed assembly of the rotating fixed assembly 4 by the feeding assembly 2. The rotating assembly drives the fixed assembly to rotate, thereby causing the seamless tube to rotate. Then, the X-axis linear assembly, Y-axis linear assembly, and Z-axis linear assembly drive one end of the seamless tube to the inspection end of the inspection assembly 5. After that, while the rotating fixed assembly 4 drives the seamless tube to rotate, the X-axis linear assembly drives the seamless tube to move along the X-axis until the weld seam is detected or the entire seamless tube body is inspected, thus completing the inspection of one seamless tube.

[0032] Preferably, the X-axis linear drive includes a first linear module 311 and a first slide rail 313, both mounted on the mounting platform 1. The first linear module 311 and the first slide rail 313 are parallel and extend along the X-axis direction. A slide plate 312 is mounted on the output end of the first linear module 311, and both ends of the slide plate 312 are slidably connected to the first slide rail 313.

[0033] Preferably, the Y-axis linear drive includes a second linear module 321 and a second slide rail 323 both mounted on the slide plate 312. The second linear module 321 and the second slide rail 323 are parallel and extend along the Y-axis direction. A slide bracket 322 is mounted on the output end of the second linear module 321, and both ends of the slide bracket 322 are slidably connected to the second slide rail 323.

[0034] Preferably, the Z-axis linear drive includes a second motor 331 and a third slide rail 334 respectively mounted on the front and back sides of the slide 322. The third slide rail 334 is close to the feeding assembly 2 and extends along the Z-axis. A mounting plate 335 is slidably mounted on the third slide rail 334. A rack 333 is mounted inside the mounting plate 335. A gear 332 is mounted on the output end of the second motor 331. The gear 332 and the rack 333 mesh. The rotating fixing assembly 4 is mounted on the mounting plate 335.

[0035] The first linear module 311, the second linear module 321, and the second motor 331 are all electrically connected to the PLC controller.

[0036] The second motor 331 drives the gear 332 and rack 333 to mesh, thereby causing the mounting plate 335 to rise and fall along the third slide rail 334.

[0037] Preferably, the fixing component includes a cylinder 41. The output end of the cylinder 41 extends and retracts along the X-axis, and a tensioning block 44 is installed on the output end. The diameter of the end of the tensioning block 44 near the feeding component 2 gradually increases. An outer tube 43 is installed outside the tensioning block 44. A petal-shaped positioning pin 45 is installed at the end of the outer tube 43 near the feeding component 2. When the output end of the cylinder 41 extends, it pushes the tensioning block 44 to move away from the moving component 3, thereby pushing the positioning pin 45 to open. The seamless tube is sleeved on the outside of the positioning pin 45. When the positioning pin 45 opens, it presses tightly against the inner wall of the seamless tube to fix the seamless tube. When the output end of the cylinder 41 retracts, it drives the tensioning block 44 to move closer to the moving component 3. Under its own elasticity, the petals of the positioning pin 45 retract, removing the abutment force on the inner wall of the seamless tube, making it easy to remove the seamless tube.

[0038] Cylinder 41 is electrically connected to the PLC controller.

[0039] The fixing method of the positioning pin 45 can adapt to seamless tubes within a certain range of diameters, improving practicality, and it also fully exposes the outer wall of the seamless tube, making inspection more convenient and comprehensive.

[0040] The outer tube 43 is installed on the output end of the rotating assembly. The outer tube 43 is rotatably installed on the mounting box 42, and the mounting box 42 is installed on the mounting plate 335.

[0041] Preferably, the rotating assembly includes a third motor 46 and a synchronizing element mounted on the mounting box 42. The driving wheel 47 of the synchronizing element is mounted on the output end of the third motor 46. The outer tube 43 is coaxially and fixedly connected to the driven wheel 48 of the synchronizing element. The outer tube 43 passes through the mounting box 42 and is rotatably connected to the mounting box 42.

[0042] The third motor 46 is electrically connected to the PLC controller.

[0043] The feeding assembly 2 includes a guide platform 21 and a V-shaped groove 22. The V-shaped groove 22 has a V-shaped cross-section with the opening facing upward. The top surface of the guide platform 21 gradually decreases near the V-shaped groove 22. A first linear assembly 23 parallel to the V-shaped groove 22 is installed on one side of the V-shaped groove 22. A pusher 24 is installed on the output end of the first linear assembly 23. The bottom end of the pusher 24 extends into the V-shaped groove 22.

[0044] Preferably, the first linear assembly 23 includes a first motor 231 and a gear and rack module 232. The gear and rack 232 is mounted on the output end of the first motor 231, and the pusher 24 is mounted on the output end of the gear and rack module 232. The first motor 231 is electrically connected to the PLC controller.

[0045] The seamless tube to be tested rolls into the V-groove 22 along the guide table 21. Then, the first linear assembly 23 is activated, which drives the pusher 24 to move towards the positioning pin 45, thereby pushing the seamless tube towards the positioning pin 45 until the positioning pin 45 is inserted into the seamless tube. The tensioning block 44 pushes towards the seamless tube to fix it. Since the seamless tube is sleeved on the positioning pin 45, and the positioning pin 45 is fixed by the tensioning block 44, damage caused by rigid contact between the seamless tube and the clamping and fixing parts is avoided.

[0046] Preferably, the pusher 24 includes a connecting plate 241 and a pusher plate 242. The connecting plate 241 is mounted on the output end of the first linear assembly 23, and the pusher plate 242 abuts against the side of the seamless tube away from the rotating fixing assembly 4. An elastic member 243 is installed between the connecting plate 241 and the pusher plate 242 away from the connecting plate 241. The elastic member 243 provides cushioning when the connecting plate 241 and the seamless tube come into contact, reducing damage caused by rigid contact.

[0047] The inspection component 5 includes a vision inspection camera 51 installed on one side of the V-groove 22. The vision inspection camera 51 is electrically connected to the PLC controller. The vision inspection camera 51 is installed on the mounting platform 1 via the frame 52, and the inspection end of the vision inspection camera 51 faces the V-groove 22.

[0048] It is worth noting that the weld refers to the mark at the welding position.

[0049] Working process: The moving component 3 drives the positioning pin 45 to one end of the V-groove 22. The seamless tube to be tested rolls into the V-groove 22 along the guide table 21. The first motor 231 starts, and the gear and rack module 232 drives the connecting plate 241 to move towards the positioning pin 45. The connecting plate 241 pushes the seamless tube to fit over the positioning pin 45. Then the cylinder 41 pushes the tensioning block 44 to move towards the seamless tube. The tensioning block 44 pushes the positioning pin 45 to press against the seamless tube.

[0050] After the seamless tube is fixed, the second motor 331 starts, drives the gear 332 to rotate, drives the rack 333 to rise, thereby driving the mounting plate 335 and the mounting box 42 to rise, thereby driving the seamless tube to rise away from the V-groove 22. The first linear module 311 and the second linear module 321 start, thereby driving one end of the seamless tube to move towards the vision inspection camera 51.

[0051] After the seamless tube is moved into place, the third motor 46 starts. The third motor 46 drives the outer tube 46 to rotate through the synchronizing component. The outer tube 46 drives the seamless tube to rotate. At the same time, the first linear module 311 drives the seamless tube to move. The visual inspection camera 51 detects in real time whether there is a weld on the outer wall of the seamless tube. If a weld is detected, the PLC controller controls the electrical appliances to stop running. The PLC controller determines that the seamless tube is unqualified. If no weld is found after all positions of the seamless tube have been inspected, the seamless tube is determined to be qualified.

[0052] The above is a test process for a set of seamless tubes. This device has a high degree of automation, and the guide table 21 can connect to the previous set of processes, resulting in high testing efficiency.
