[0002] Steel pipes, as important raw materials, are widely used in industries such as petroleum, chemical, electric power, shipbuilding, and automotive. However, during the production process of steel pipes, due to various reasons such as raw materials, rolling equipment, and processing technology, different types of defects may appear on the surface, such as scratches, roller marks, scale, holes, cracks, etc. These defects not only affect the appearance of the product but also reduce its properties such as corrosion resistance, wear resistance, and fatigue strength, bringing adverse effects and safety hazards to the development of enterprises and the use of downstream products with steel pipes as raw materials. Therefore, it is particularly important to perform non-destructive detection on the surface defects of steel pipes. This kind of detection can discover surface defects without damaging the steel pipes, ensure the quality and safety of steel pipes, and provide a basis for the adjustment of production processes and the improvement of equipment status.

Detailed implementation mode

[0039] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1:

[0041] Please refer to Figures 1 - 9, this application provides a precision detection device for three-dimensional scanning, including a support plate 1, on which a scanning detection mechanism 2 is installed. The scanning detection mechanism 2 includes a driving unit 21. Among them, the driving unit 21 includes a first driving motor 211 fixedly connected to the support plate 1. The output end of the first driving motor 211 is fixedly connected to a driving shaft 212. The output end of the first driving motor 211 can drive the driving shaft 212 to rotate. Two symmetrically arranged first transmission gears 213 are fixedly connected to the driving shaft 212. The driving shaft 212 drives the two first transmission gears 213 thereon to rotate. And the scanning detection mechanism 2 further includes a support seat 22 fixedly connected to the support plate 1. The driving shaft 212 is rotatably connected to the support seat 22. A complete tooth ring 24 is meshed above each of the first transmission gears 213. The driving unit 21 is used to drive the complete tooth ring 24 to rotate. And an incomplete tooth ring 25 is fixedly connected to the complete tooth ring 24. And the two incomplete tooth rings 25 are arranged at the middle positions of the two complete tooth rings 24. An annular guide groove 26 is provided on both the complete tooth ring 24 and the incomplete tooth ring 25. A guide shaft 23 is provided on the support seat 22. One end of the guide shaft 23 away from the support seat 22 is fixedly connected with a guide block that can cooperate with the guide groove 26. Specifically, the guide block provides support for the complete tooth ring 24 and the incomplete tooth ring 25, and the complete tooth ring 24 and the incomplete tooth ring 25 can rotate along the guide block. A magnetic guide rail 28 is fixedly installed between the adjacent surfaces of the two incomplete tooth rings 25. And the magnetic guide rail 28 is installed at a position far from the center of the incomplete tooth ring 25, as long as it is ensured that it will not collide with the steel pipe during rotation. A magnetic slider 29 that is used in conjunction with the magnetic guide rail 28 is provided on the magnetic guide rail 28. A three-dimensional scanning component 210 for detecting the surface of the steel pipe is provided on the magnetic slider 29. Here it should be noted that, Figure 2 the three-dimensional scanning component 210 in is in the initial position before detecting the steel pipe. And the magnetic guide rail 28, the magnetic slider 29 and the three-dimensional scanning component 210 are all existing products. Only their use is involved. The magnetic guide rail 28 and the magnetic slider 29 are used by being electrified. And the three-dimensional scanning component 210 will display the constructed model on the control terminal display screen provided on the support plate 1 by means of an internal three-dimensional laser scanning component and an analysis component. They are all existing products, so they are directly used without detailed description.

[0042] Specifically, the complete tooth ring 24 is rotated by the drive of the drive unit 21, thereby driving the incomplete tooth ring 25 to rotate. Moreover, the guide grooves 26 on the complete tooth ring 24 and the incomplete tooth ring 25 slide relative to the guide blocks on the guide shaft 23. The incomplete tooth ring 25 drives the inner magnetic guide rail 28 to rotate one week around the surface of the steel pipe to be detected. By moving the magnetic slider 29 on the magnetic guide rail 28, the three-dimensional scanning assembly 210 is moved left and right, realizing a comprehensive scanning and detection of the steel pipe, improving the detection accuracy. Compared with the traditional method of using a fixed three-dimensional scanning assembly 210 to detect the steel pipe, which results in the back of the steel pipe not being effectively scanned, the detection effect is better.

[0043] Embodiment 2:

[0044] On the basis of Embodiment 1, the scanning and detection mechanism 2 further includes an automatic material taking component 27. Among them, a support frame 7 is further fixedly installed on the support plate 1. The automatic material taking component 27 includes a fixed block 271 fixedly connected to the support frame 7. A first connecting frame 272 is fixedly connected to the fixed block 271. A chute 273 is provided on the first connecting frame 272. A first slider 275 is slidably connected inside the chute 273. A rack 276 used in cooperation with the incomplete tooth ring 25 is provided on the first slider 275. Here, it should be noted that the teeth 104 on the incomplete tooth ring 25 are incomplete. During the detection of the steel pipe, as the complete tooth ring 24 rotates, it drives the incomplete tooth ring 25 to rotate, causing the teeth 104 on the incomplete tooth ring 25 to contact the teeth 104 on the rack 276. Then, the rack 276 slides down along the chute 273 through the first slider 275 until the adsorption electromagnet 12 contacts the detected steel pipe. A first return spring 274 for resetting the first slider 275 is further provided inside the chute 273, facilitating the first slider 275 to drive the rack 276 to be jacked up under the action of the first return spring 274 when the teeth 104 on the rack 276 are disengaged from the teeth 104 on the incomplete tooth ring 25. The upper end of the rack 276 is fixedly connected to a connecting rod 277.

[0045] Specifically, during the process of the rotation of the complete gear ring 24 causing the three-dimensional scanning assembly 210 to rotate around the outer surface of the steel pipe for detection, and when the complete gear ring 24 rotates a certain angle, the incomplete gear ring 25 on it fits with the rack 276 and pulls the rack 276 to move downward. The rack 276 drives the connecting rod 277 to move downward, and the automatic material taking assembly 27 drives the transfer mechanism 4 and all components installed on the transfer mechanism 4, including the adsorption electromagnet 12, to move downward until the complete gear ring 24 rotates one full circle, and the teeth 104 on the incomplete gear ring 25 are disengaged from the teeth 104 on the rack 276 again. Here, it should be noted that the condition for the teeth 104 on the incomplete gear ring 25 to be disengaged from the teeth 104 on the rack 276 is that after the complete gear ring 24 rotates one full circle, it pauses for a moment, and then the first driving motor 211 makes the complete gear ring 24 rotate slightly by a certain angle. At this time, the condition for the teeth 104 on the rack 276 to be disengaged from the teeth 104 on the incomplete gear ring 25 can be achieved. After that, under the action of the first return spring 274, the first slider 275 is pushed up until the top of the first slider 275 touches the top of the chute 273. Then, the first driving motor 211 is driven in the reverse direction to reset the complete gear ring 24.

[0046] In this embodiment, the transfer mechanism 4 is fixedly installed on the connecting rod 277. The transfer mechanism 4 includes a fixed slide rail 44 fixedly connected to the connecting rod 277. A second driving motor 41 is fixedly connected to the outer wall of the fixed slide rail 44. The output end of the second driving motor 41 is fixedly connected to a lead screw 42, and the lead screw 42 is rotatably connected to the fixed slide rail 44. A moving seat 43 that can slide on the fixed slide rail 44 is threadedly connected to the lead screw 42.

[0047] Specifically, by starting the second driving motor 41 to drive the lead screw 42 to rotate, the rotation of the lead screw 42 causes the moving seat 43 to slide along the fixed slide rail 44, thereby realizing the transfer of the steel pipe to the detection station and sending the steel pipe after detection to the conveyor belt assembly 6.

[0048] In this embodiment, a height-adjusting mechanism 8 is provided on the moving seat 43. The height-adjusting mechanism 8 includes two second fixed sleeve columns 81 arranged side by side and fixedly connected to the bottom wall of the moving seat 43. Each of the second fixed sleeve columns 81 is provided with threaded holes 82 arranged at equal intervals. A third fixed sleeve column 9 is slidably arranged inside the second fixed sleeve column 81. A bolt 83 for fixing the third fixed sleeve column 9 can be arranged inside any one of the threaded holes 82. By tightening the bolt 83 inside the corresponding threaded hole 82, the third fixed sleeve column 9 is restricted inside the second fixed sleeve column 81, facilitating the adjustment of the relative lengths of the second fixed sleeve column 81 and the third fixed sleeve column 9 according to actual needs. When the radius of the steel pipes in the same batch is slightly larger, the third fixed sleeve column 9 can be retracted more inside the second fixed sleeve column 81. Conversely, the third fixed sleeve column 9 can be drawn out more from inside the second fixed sleeve column 81, ensuring that during the descent of the adsorption electromagnet 12, it can contact the steel pipe, facilitating the adaptation to the requirements of steel pipes with different radii.

[0049] In this embodiment, a fixed seat 11 is installed on the third fixed sleeve column 9, and an adsorption electromagnet 12 is installed on the fixed seat 11. The adsorption electromagnet 12 is a prior art and is used by being energized. When the adsorption electromagnet 12 contacts the detected steel pipe, the adsorption electromagnet 12 is energized to generate a magnetic field and adsorbs on the outer surface of the steel pipe.

[0050] In summary of this embodiment, after the three-dimensional scanning assembly 210 rotates to scan the steel pipe for one week, the adsorption electromagnet 12 automatically adheres to the surface of the steel pipe and adsorbs the steel pipe by being energized. Moreover, the initial height of the adsorption electromagnet 12 can be adjusted by the height-adjusting mechanism 8, facilitating the adaptation to steel pipes with different radii. Compared with the traditional method of manually removing and replacing the steel pipe for single detection of the steel pipe, the operation is more concise and the continuity is higher.

[0051] Embodiment Three:

[0052] On the basis of Embodiment Two, a limiting mechanism 3 is installed on the support frame 7 for clamping both ends of the detected steel pipe. The limiting mechanism 3 includes two first fixed sleeve columns 31 fixedly connected to the support frame 7, and the opening directions of the two first fixed sleeve columns 31 are opposite. A movable rod 33 is slidably connected inside the first fixed sleeve column 31, and a second return spring 32 is arranged between the movable rod 33 and the first fixed sleeve column 31, facilitating the clamping by the elastic force of the second return spring 32 after the steel pipe is placed between the two limiting disks 34. A limiting disk 34 is fixedly connected to the end of the movable rod 33 away from the second return spring 32, and an L-shaped connecting plate 35 is arranged on the limiting disk 34.

[0053] Specifically, when the steel pipe to be detected adsorbed by the adsorption electromagnet 12 is placed between the two limit discs 34, the movable rod 33 contracts into the first fixed sleeve column 31, and the steel pipe is clamped by the second return spring 32 to ensure the stability during the detection of the steel pipe, avoiding the problem that the steel pipe shakes due to the vibration generated by the machine during the detection process, which in turn affects the comprehensiveness of the steel pipe detection and is prone to missed detection.

[0054] Embodiment 4:

[0055] On the basis of Embodiment 3, a set of clamping release mechanisms 10 are installed on each of the third fixed sleeve columns 9, and the initial states of the two sets of clamping release mechanisms 10 are opposite, that is, the initial state of one set of clamping release mechanisms 10 is the end state of the other set of clamping release mechanisms 10. Among them, the clamping release mechanism 10 includes a fixed electromagnet block 101 fixedly connected inside the third fixed sleeve column 9, and a movable electromagnet block 102 slidably connected inside the third fixed sleeve column 9, and the movable electromagnet block 102 is used in combination with the fixed electromagnet block 101. The fixed electromagnet block 101 and the movable electromagnet block 102 are both prior arts. By changing the direction of the current, the magnetism of the fixed electromagnet block 101 and the movable electromagnet block 102 is changed. A sliding shaft 103 is fixedly connected to the lower end of the movable electromagnet block 102. Tooth teeth 104 are provided on both sides of the sliding shaft 103. A connecting block 1011 is fixedly connected to the lower end of the fixed seat 11. A rotating shaft 107 is rotatably connected to the connecting block 1011. A second transmission gear 105 is fixedly connected to the rotating shaft 107. And there are two second transmission gears 105 which are respectively meshed with the tooth teeth 104 on both sides of the sliding shaft 103. A connecting seat 106 is fixedly connected to each of the second transmission gears 105. The connecting seat 106 is connected to the wheel seat 109 through a V-shaped connecting frame 108. A roller 1010 is provided on the wheel seat 109, and the roller 1010 is used in combination with the L-shaped connecting plate 35 on the limit disc 34.

[0056] In this embodiment, a stepping feeding component 5 is installed on the support plate 1 for step-by-step conveying of the steel pipe. The conveying method is a common prior art method, so no more description will be given. A conveyor belt component 6 is installed on the support frame 7 for loosening and leaving the detected steel pipe, which is also a common prior art method. And when the three-dimensional scanning component 210 detects the steel pipe and it is placed on the conveyor belt component 6, it can be taken off manually or by a manipulator to ensure that the conveyed steel pipes are all qualified.

[0057] The specific operation steps of this example are as follows: the initial positions of the two groups of clamping mechanisms 10 are respectively one group is set just above the material taking platform of the step feeding component 5, and the other group of clamping mechanisms 10 is set just above the inspection steel pipe. When the automatic material taking component 27 drives the two groups of clamping mechanisms 10 thereon to move downward, one group of clamping mechanisms 10 uses the adsorption electromagnet 12 thereon to magnetically absorb the uninspected steel pipe on the material taking platform of the step feeding component 5, and the adsorption electromagnet 12 on the other group of clamping mechanisms 10 absorbs the steel pipe after the inspection is completed, and the distance between the rollers 1010 in the clamping mechanism 10 above the inspection steel pipe is slightly smaller than the distance between the two limit plates 34, so that in the process of its descent, the two limit plates 34 will not be directly opened, resulting in the adsorption electromagnet 12 not directly opening the two limit plates 34. 12 has not yet sucked the steel pipe, the steel pipe loses its clamping force and falls. When the adsorption electromagnet 12 sucks the steel pipe, the current direction of the fixed electromagnetic block 101 and the movable electromagnetic block 102 is changed, so that the fixed electromagnetic block 101 and the movable electromagnetic block 102 attract each other with opposite sexes, thereby driving the sliding shaft 103 to shrink toward the inside of the third fixed sleeve column 9, and driving the second transmission gear 105 to rotate through the teeth 104. The second transmission gear 105 drives the wheel seat 109 to rotate through the connecting seat 106 and the V-shaped connecting frame 108. Because the V-shaped connecting frame 108 is in an inclined state, the rotation of the V-shaped connecting frame 108 lengthens the horizontal distance between the rollers 1010 on the wheel seat 109, thereby expanding the two limit plates 34. At this time, the space between the two limit plates 34 can be taken out. The steel pipe is automatically released and the clamping force is released. During this process, another group of adsorption electromagnets 12 used in conjunction with the loosening mechanism 10 suck up the undetected steel pipe on the picking table of the step feeding component 5. After that, the undetected steel pipe is moved to the top of the detection area through the transportation of the transfer mechanism 4, and the detected steel pipe is transported by the transfer mechanism 4 to the top of the conveyor belt component 6, and then the complete gear ring 24 and the incomplete gear ring 25 are made to idle for one circle through the driving unit 21, so that the two adsorption electromagnets 12 and the steel pipe adsorbed by the two adsorption electromagnets 12 are lowered. At this time, the adsorption electromagnet 12 loses its magnetic force by cutting off the power, and the detected steel pipe is brought close to the surface of the step feeding component 5 and released onto the step feeding component 5, while the other group of adsorption electromagnets The magnet 12 drives the steel pipe to be placed between the two limit plates 34. Since the initial state of the loosening mechanism 10 is opposite to the initial state of the other loosening mechanism 10, the roller 1010 can open the L-shaped connecting plate 35 on the limit plate 34 before the steel pipe enters the limit plate 34 area, that is, the limit plate 34 is opened so that the steel pipe can be placed between the two limit plates 34. Before this group of adsorption electromagnets 12 is powered off to release the steel pipe, the fixed electromagnetic block 101 and the movable electromagnetic block 102 in this group of loosening mechanisms 10 need to repel each other with the same polarity, thereby causing the sliding shaft 103 to move downward, and the V-shaped connecting frame 108 to rotate through the teeth 104 and the second transmission gear 105 until the roller 1010 thereon has no supporting force on the limit plate 34.Furthermore, it can clamp this steel pipe through the second reset spring 32. Thus, the automatic clamping and releasing of the steel pipe before and after detection are realized, with stronger continuity and faster response speed.

[0058] In summary, the precision detection device for three-dimensional scanning not only improves the detection accuracy and comprehensiveness, but also realizes automatic material replacement, continuous detection, adaptation to steel pipes of different sizes, stable clamping, and automatic clamping and releasing, overall improving the detection efficiency and automation level.

[0059] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
