Description

Technical Field

[0001] This invention relates to the technical field of stainless steel pipe grinding equipment, specifically to a high-efficiency stainless steel pipe surface micro-crack grinding equipment. Background Technology

[0002] During the manufacturing and service of stainless steel pipes, micro-cracks on the surface are a critical defect affecting the structural integrity and service life of the pipes. To ensure the safe operation of the pipeline system, it is essential to efficiently and accurately grind and repair these cracks. However, existing traditional grinding equipment suffers from several technical bottlenecks in practical applications, severely restricting repair quality and efficiency. Firstly, during grinding, the pipe cracks may lack a positioning reference or have insufficient accuracy. Current grinding equipment largely relies on manual marking and a manual positioning structure, lacking a unified mechanical linkage positioning reference, resulting in large errors in crack location identification. This is especially problematic for micro-cracks less than 0.1mm wide, which are difficult to accurately align, causing… The grinding loss rate is as high as 30%, which seriously affects the reliability of stainless steel pipe repair. Secondly, most equipment uses a rigid fixed installation method for the grinding head. When there are local unevenness on the surface of the steel pipe, it will cause violent fluctuations in grinding pressure. This not only keeps the crack removal rate at only about 78%, but also results in low surface roughness after repair, which cannot meet the requirements of high-precision industrial standards. At the same time, most grinding equipment is an open design that cannot collect the dust generated during grinding. Most traditional equipment generally uses a fixed dust collection hood, which is inconvenient to collect dust when the grinding head moves along the curved surface of the steel pipe. It is also easy for dust to leak out and scatter, making it extremely inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency stainless steel pipe surface micro-crack grinding device to solve the problems mentioned in the background art, such as large identification errors and easy omission of dust due to the use of manual marking during grinding.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency stainless steel pipe surface micro-crack grinding device, comprising a base, an upper frame fixedly installed at the end of the base away from the ground, and the upper frame having a frame design; a control console placed on one side of the base; a grinding robot fixedly placed on the side of the base away from the control console; a base plate slidably installed on the outer surface of the base, and the base plate having a bucket-shaped inclined design; a search vision camera fixedly installed on one side of the outer surface of the upper frame, and the search vision camera being located at the four corners of the upper frame; a viewing camera fixedly installed on the top outer surface of the upper frame, and the viewing camera having an inclined design and being located on the opposite side of the grinding robot; and a re-inspection mechanism provided on one end of the outer surface of the upper frame.

[0005] Preferably, the re-inspection mechanism includes a re-inspection vision camera, which is fixedly installed on the side of the upper shelf away from the search vision camera. The re-inspection vision cameras are located at the four corners of the upper shelf. Both the re-inspection vision camera and the search vision camera are equipped with a rotating shaft. Supplemental light strips are fixedly installed at both ends of the upper shelf, and the supplemental light strips are designed to face each other.

[0006] By using the above technical solution, supplementary lighting can be provided to the search vision camera and the re-inspection vision camera, allowing them to more clearly see the cracks and defects in the stainless steel pipe and the condition of the stainless steel pipe after grinding. If the re-inspection vision camera detects that the grinding is not up to standard, the steel pipe can be retracted to one side of the grinding robot via an electric roller for rework.

[0007] Preferably, a front observation plate is fixedly installed at the end of the upper frame near the control console, and a rear plate frame is fixedly installed at the end of the upper frame away from the front observation plate. The rear plate frame and the front observation plate are respectively fixed to the base and the upper frame with screws.

[0008] By adopting the above technical solution, the screw fixing setting allows the rear plate frame and front observation plate to be removed from the base and upper frame during maintenance or overall cleaning. This facilitates the cleaning and maintenance of the grinding equipment while allowing real-time observation of the stainless steel pipe being ground through the front observation plate.

[0009] Preferably, a pressure plate frame is fixedly installed on the outer surface of the rear frame, and a skin cover is fixedly installed between the pressure plate frame and the rear frame. The skin cover has a bucket-shaped design, one end of which is a retractable rope design, and one end of the skin cover is in contact with the outer surface of the grinding robot. Blind curtains are fixedly installed on both outer surfaces of the upper frame, and elastic bands are fixedly installed on the outer surface of the blind curtains. The outer surface of the elastic bands is in contact with the outer surface of the stainless steel tube. A pressure sensor is fixedly installed on the outer surface of the grinding robot.

[0010] By employing the above technical solution, the use of a shielding curtain and elastic band allows stainless steel pipes of different diameters to pass through while blocking most of the space. Simultaneously, the pressure plate frame secures the skin cover, creating a flexible connection between the skin cover and the grinding robot. This allows the grinding robot to move freely without restriction and effectively shields the dust generated during grinding, significantly reducing environmental pollution caused by dust and gas leakage during grinding. Furthermore, it does not affect the grinding robot's flexibility. Combined with the use of pressure sensors, this allows the grinding robot to grind more evenly when treating cracks on the surface of stainless steel pipes.

[0011] Preferably, a secondary roller is rotatably mounted on the side of the base plate near the front observation plate, a primary roller is rotatably mounted on the side of the base plate near the rear plate frame, a servo motor is fixedly mounted on one side of the base plate, and the output end of the servo motor is connected to the primary roller. The servo motor is connected to the control console, and the primary roller and the secondary roller are cylinders made of rubber.

[0012] By adopting the above technical solution, the rotation of the servo motor drives the active roller to rotate. In conjunction with the similar materials of the active roller and the auxiliary roller, the rotation of the active roller can carry the stainless steel tube and the auxiliary roller to rotate. After the stainless steel tube detects the crack, it can rotate and face the grinding robot. At the same time, in conjunction with the grinding action of the grinding robot and the rotation of the stainless steel tube, the stainless steel tube can be ground more conveniently and the grinding quality can be guaranteed.

[0013] Preferably, a guide cover is fixedly installed on the outer surface of the base plate, and the guide cover is located below the active roller and the auxiliary roller. A blower is fixedly installed at the end of the upper frame away from the base, and the blower is located above the guide cover. An adsorption collection mechanism is provided between the base and the upper frame.

[0014] By adopting the above technical solution, through the use of a fan and a guide cover, the grinding robot can further forcibly remove the dust generated during the grinding of stainless steel pipes, thereby further reducing the pollution of the surrounding environment by flying dust and the harm to workers.

[0015] Preferably, the adsorption and collection mechanism includes: an ash storage box, which is fixedly installed on the outer surface of the base, and the base and the guide cover are connected by a spring tube; a suction motor is fixedly installed on one side of the ash storage box, and the suction motor is connected to one end of the ash storage box; a filter drawer is inserted into the ash storage box, and a filter plate is snapped into the filter drawer; a rotating buckle is rotatably installed on the outer surface of the ash storage box, and the rotating buckle fits against the outer surface of the filter drawer.

[0016] By employing the above technical solution, the air inside the upper shelf can be extracted using a suction motor, allowing the dust-laden air to be drawn into the dust collection box. The dust is then filtered through a filter plate, allowing the metal dust to be collected and stored inside the filter drawer. This facilitates dust collection for centralized cleaning, recycling, and reuse. Furthermore, the filter plate can be removed from the filter drawer for washing or easily replaced if damaged, greatly improving the convenience of cleaning and maintenance.

[0017] Preferably, guide rods are fixedly installed on both sides of the base plate, and the guide rods pass through the outer surface of the base. The base and the guide rods are slidably connected. A pushing adjustment mechanism is provided between the guide rods and the base. The pushing adjustment mechanism includes an electric push rod, which is fixedly installed on the side of the base near the ash storage box. The base is passed through by the output end of the electric push rod, and the output end of the electric push rod is connected to the base plate. A limit sleeve is inserted and installed on the outer surface of the guide rod. A locking nut is threaded on one end of the guide rod, and the outer surface of the locking nut is in contact with the outer surface of the limit sleeve.

[0018] By using the above technical solution, the use of locking nuts and the insertion of guide rods into the limiting sleeves allows the electric push rod to push the base plate out, and then quickly push the active roller and auxiliary roller to the limited height. The height of the base plate can be adjusted by changing the limiting sleeves of different lengths. This allows the active roller and auxiliary roller to lift and rotate the stainless steel pipes of different diameters, greatly improving the versatility of processing and grinding stainless steel pipes.

[0019] Preferably, a fixed frame is fixedly installed on both sides of the base, and a sliding rod is slidably installed on the outer surface of the fixed frame. The two ends of the sliding rod are designed to be inclined. An electric roller is inserted and fixed at both ends of the sliding rod. The two ends of the electric roller are designed to be flat. The electric roller engages with the sliding rod. The electric roller is connected to the control console.

[0020] By adopting the above technical solution, the electric roller can lift stainless steel pipes of different diameters by using fixed frames and sliding rods with fixed intervals. The rotation direction of the electric roller can be adjusted according to the processing requirements, and it can be flexibly adjusted according to the diameter of the stainless steel pipe, ensuring versatility while allowing the stainless steel pipe to be moved.

[0021] Preferably, the outer surface of one side of the sliding rod is provided with scale lines, the outer surface of one side of the fixing frame is threaded with fixing bolts, and the fixing bolts are in contact with the outer surface of the sliding rod, and the electric roller is a V-shaped design.

[0022] By adopting the above technical solution, the length of the fixing frame and sliding rod can be viewed and adjusted as needed, allowing the sliding rod to be accurately and quickly confirmed and adjusted to ensure the consistency of the height of the fixing frame and sliding rod. This ensures that the stainless steel pipe remains parallel to the bottom edge after the height is adjusted, improving the convenience and accuracy of adjustment and preventing the stainless steel pipe from being difficult to move due to tilting or other reasons.

[0023] Compared with the prior art, the beneficial effects of this invention are: This high-efficiency stainless steel pipe surface micro-crack grinding equipment: 1. The four-corner design of the vision camera can quickly record and identify the passing stainless steel pipes, allowing the detection of tiny cracks on the surface of the stainless steel pipes. After the polishing robot finishes polishing the stainless steel pipes and pushes them out, the follow-up vision camera can be used to check the polished stainless steel pipes. In addition, the inspection camera can be used to check the working status of the polishing robot inside the stainless steel pipes, reducing the omissions caused by manual inspection and greatly improving the efficiency of finding and processing stainless steel pipes. 2. The stainless steel tube is moved by an electric roller, allowing it to pass through and open the shielding curtain and elastic band, blocking most of the gaps at both ends of the upper frame. The gaps in the upper frame are also blocked by the front observation plate and the rear plate frame. At the same time, in conjunction with the connection between the skin cover and the polishing robot, the polishing robot's movements are not restricted, and dust will not be scattered when polishing stainless steel tubes of different diameters, reducing dust pollution to the environment and the difficulty of cleaning. 3. When the grinding device is in use, the blower and the suction motor will work simultaneously to create convection inside the upper shelf. This allows the dust generated during grinding to be quickly carried away by the convection. The inclined design inside the base plate makes it easier and more convenient for the dust to be carried into the dust collection box. The dust is then filtered by the filter plate and stored in the filter drawer. This facilitates the collection and concentration of the dust generated during grinding. It is also convenient to remove the filter drawer for emptying or recycling, which greatly reduces the difficulty of cleaning and the chance of dust escaping. 4. When dealing with stainless steel pipes of different diameters, the position of the sliding rod on the fixed frame can be quickly adjusted through the scale lines and fixed with the fixing bolts. With the V-shaped design of the electric roller, stainless steel pipes of different diameters can be supported, allowing the stainless steel pipes to be maintained in the preset grinding position. This facilitates the support and back-and-forth movement of stainless steel pipes of different diameters, allowing the grinding robot to be fixed and only the stainless steel pipe to move, without the grinding robot moving back and forth. This facilitates the support and movement of stainless steel pipes of different diameters, reduces the failures caused by the grinding robot moving back and forth, and greatly improves the processing efficiency of stainless steel pipes. 5. During use, the thickness of the limiting sleeve on the guide rod can be adjusted according to the diameter of the stainless steel tube and fixed by the locking nut. After the electric push rod pushes out the base plate, it can be limited by the limiting sleeve, allowing the active roller and the auxiliary roller to move quickly and accurately to the required position. When facing stainless steel tubes of different diameters, the active roller and the auxiliary roller can accurately and quickly contact the outer surface of the stainless steel tube. With the operation of the servo motor, the stainless steel tube can be lifted and rotated when grinding is required. After grinding is completed, the stainless steel tube can be disengaged from the active roller and the auxiliary roller without affecting the movement of the stainless steel tube. The lateral movement and rotation of the stainless steel tube are not affected by each other, further improving the convenience of grinding stainless steel tubes. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-10 This invention provides a technical solution: a high-efficiency stainless steel pipe surface micro-crack grinding device includes a base 1, an upper frame 2 fixedly installed at the end of the base 1 away from the ground, and the upper frame 2 is a frame design. A control console 34 is placed on one side of the base 1, and a grinding robot 5 is fixedly placed on the side of the base 1 away from the control console 34. A base plate 11 is slidably installed on the outer surface of the base 1, and the base plate 11 is a bucket-shaped inclined design. A search vision camera 8 is fixedly installed on one side of the outer surface of the upper frame 2, and the search vision cameras 8 are respectively located at the four corners of the upper frame 2. A viewing camera 21 is fixedly installed on the top outer surface. The viewing camera 21 is tilted and located on the opposite side of the polishing robot 5. A re-inspection mechanism is provided on the outer surface of one end of the upper frame 2. The re-inspection mechanism includes a re-inspection vision camera 10. The vision camera 10 is fixedly installed on the side of the upper frame 2 away from the search vision camera 8. The re-inspection vision cameras 10 are located at the four corners of the upper frame 2. Both the re-inspection vision camera 10 and the search vision camera 8 are equipped with a rotating shaft. Fill light strips 9 are fixedly installed at both ends of the upper frame 2, and the fill light strips 9 are designed to face each other.

[0028] Firstly, during use, the stainless steel tube will move smoothly with the support and rotation of the electric roller 32, allowing it to pass through one end of the upper frame 2 and exit from the other end. The illumination of the supplementary light strip 9 enables the visual camera 8 to inspect and mark the passing stainless steel tube in one go. In conjunction with the rotation of the inspection camera 21 and the electric roller 32, the area of ​​the stainless steel tube requiring polishing is moved to one side of the polishing robot 5. After the polishing robot 5 completes polishing and moves out from the other side of the upper frame 2 and base 1, the review visual camera 10 can inspect the stainless steel tube again to re-check the polished area. If any polishing defects are detected, the stainless steel tube is returned by the electric roller 32 for re-polishing, greatly reducing the chance of missed markings and unqualified polishing, and improving the efficiency of processing and polishing stainless steel tubes.

[0029] A front observation plate 3 is fixedly installed at one end of the upper frame 2 near the control console 34, and a rear plate frame 4 is fixedly installed at the other end of the upper frame 2 away from the front observation plate 3. The rear plate frame 4 and the front observation plate 3 are fixed to the base 1 and the upper frame 2 respectively with screws. A pressure plate frame 7 is fixedly installed on the outer surface of the rear plate frame 4, and a skin cover 6 is fixedly installed between the pressure plate frame 7 and the rear plate frame 4. The skin cover 6 has a bucket-shaped design, and one end of the skin cover 6 has a retractable rope design. One end of the skin cover 6 is in contact with the outer surface of the grinding robot 5. A shielding curtain 22 is fixedly installed on both outer surfaces of the upper frame 2, and an elastic band 23 is fixedly installed on the outer surface of the shielding curtain 22. The outer surface of the elastic band 23 is in contact with the outer surface of the stainless steel tube. A pressure sensor 35 is fixedly installed on the outer surface of the grinding robot 5.

[0030] Secondly, when grinding generates dust, the tension of the front observation plate 3, rear frame 4, shielding curtain 22, and elastic band 23 will block the dust generated during grinding and wrap the stainless steel tube as much as possible, reducing the chance of grinding dust overflowing. At the same time, the use of pressure plate frame 7 and skin cover 6 allows the grinding part of the grinding robot 5 to work inside the upper frame 2 without restriction and to move flexibly. With the use of pressure sensor 35, the grinding robot 5 can drive the active roller 12, auxiliary roller 14, and stainless steel tube to rotate with appropriate force and angle, in conjunction with servo motor 13. This allows for better grinding quality when grinding cracks in the stainless steel tube and prevents dust overflow, greatly improving the grinding quality of the grinding device and reducing environmental pollution caused by grinding dust overflow.

[0031] A secondary roller 14 is rotatably mounted on the side of the base plate 11 near the front observation plate 3, and a primary roller 12 is rotatably mounted on the side of the base plate 11 near the rear frame 4. A servo motor 13 is fixedly mounted on one side of the base plate 11, and the output end of the servo motor 13 is connected to the primary roller 12. The servo motor 13 is connected to the control console 34. The primary roller 12 and the secondary roller 14 are cylindrical objects made of rubber. Guide rods 25 are fixedly mounted on both sides of the base plate 11, and the guide rods 25 penetrate the outer surface of the base 1. The base 1 and the guide rods 25 are connected to the outer surface of the base 1. The rod 25 is slidably connected. A pushing adjustment mechanism is provided between the guide rod 25 and the base 1. The pushing adjustment mechanism includes an electric push rod 24, which is fixedly installed on the side of the base 1 near the ash storage box 16. The output end of the electric push rod 24 passes through the base 1 and is connected to the base plate 11. A limit sleeve 26 is inserted and installed on the outer surface of the guide rod 25. A locking nut 27 is threaded on one end of the guide rod 25, and the outer surface of the locking nut 27 is in contact with the outer surface of the limit sleeve 26.

[0032] Furthermore, when dealing with stainless steel pipes of different diameters, a limiting sleeve 26 of corresponding length needs to be selected according to the diameter of the stainless steel pipe and inserted into the guide rod 25. With the fixing and use of the locking nut 27, after the electric push rod 24 pushes out the base plate 11, the base plate 11 can move up and down along the direction of the guide rod 25. With the rotation of the servo motor 13, when the stainless steel pipe needs to be polished, the active roller 12 and the auxiliary roller 14 can move up and lift the stainless steel pipe and rotate it, so as to facilitate the rotation and movement of the stainless steel pipe for polishing, which greatly improves the convenience and versatility of the polishing device.

[0033] A guide cover 15 is fixedly installed on the outer surface of the base plate 11, and the guide cover 15 is located below the active roller 12 and the auxiliary roller 14. A blower 20 is fixedly installed on the end of the upper frame 2 away from the base 1, and the blower 20 is located above the guide cover 15. An adsorption collection mechanism is provided between the base 1 and the upper frame 2. The adsorption collection mechanism includes: a dust collection box 16, which is fixedly installed on the outer surface of the base 1, and the base 1 and the guide cover 15 are connected by a spring tube. A suction motor 17 is fixedly installed on one side of the dust collection box 16, and the suction motor 17 is connected to one end of the dust collection box 16. A filter drawer 18 is inserted into the inside of the dust collection box 16, and a filter plate 19 is snapped into the inside of the filter drawer 18. A rotating buckle 33 is rotatably installed on the outer surface of the dust collection box 16, and the rotating buckle 33 is in contact with the outer surface of the filter drawer 18.

[0034] Furthermore, when the grinding robot 5 grinds the stainless steel pipe and generates dust, the use of the suction motor 17 and the blower 20 will create convection inside the upper frame 2. At the same time, the generated dust will be sucked into the dust collection box 16 through the guide cover 15, and filtered by the filter plate 19 and stored inside the filter drawer 18. The dust is collected and the rotating buckle 33 is opened at the end of the shift, and the filter drawer 18 is taken out from the dust collection box 16 for cleaning and emptying. This further reduces the chance of dust overflow from the grinding device and allows the collected dust to be recycled and reused.

[0035] A mounting bracket 28 is fixedly installed on both sides of the base 1. A sliding rod 29 is slidably installed on the outer surface of the mounting bracket 28. The two ends of the sliding rod 29 are inclined. An electric roller 32 is inserted and fixed to both ends of the sliding rod 29. The two ends of the electric roller 32 are flat. The electric roller 32 engages with the sliding rod 29 and is connected to the control console 34. A scale line 30 is opened on one side of the outer surface of the sliding rod 29. A fixing bolt 31 is threaded on one side of the outer surface of the mounting bracket 28 and fits against the outer surface of the sliding rod 29. The electric roller 32 has a V-shaped design.

[0036] Secondly, when dealing with stainless steel pipes of different diameters, the positions of the fixing frame 28 and the sliding rod 29 can be quickly adjusted according to the scale line 30, and then fixed by tightening the fixing bolt 31. The V-shaped design of the electric roller 32 facilitates the support of stainless steel pipes of different diameters, improves the convenience of adjusting the height of the electric roller 32, and can push the stainless steel pipe to move according to the location of the crack detected on the stainless steel pipe, further improving the versatility of the grinding device for stainless steel pipes.

[0037] Working principle: During use, a limiting sleeve 26 of corresponding length needs to be selected according to the size of the stainless steel pipe. The limiting sleeve 26 is then secured to the outer surface of the guide rod 25 using the locking nut 27. Subsequently, the position between the fixing frame 28 and the sliding rod 29 is quickly adjusted according to the scale line 30 and locked using the fixing bolt 31, ensuring that all electric rollers 32 are at the same height. The stainless steel pipe can then be placed between the electric rollers 32, and the rotation of the electric rollers 32 slowly moves the stainless steel pipe, allowing it to enter from one side of the upper frame 2 and exit from the other. Combined with the illumination from the supplementary light strip 9 and the omnidirectional viewing of the stainless steel pipe by the search vision camera 8, this facilitates easy access... The vision camera 8 precisely marks the tiny cracks on the surface of the stainless steel tube, and the electric roller 32 pushes the stainless steel tube out in a quantitative manner so that the area to be polished is moved to one side of the polishing robot 5. Then, the electric push rod 24 pushes the base plate 11 to rise, and the servo motor 13 drives the active roller 12 and the auxiliary roller 14 to rotate. Then, the polishing robot 5 polishes the area of ​​the stainless steel tube that needs to be polished. With the use of the pressure sensor 35, the polishing robot 5 can apply more force during polishing to improve the polishing quality of the stainless steel tube. After the stainless steel tube is moved out from the other side of the upper shelf 2, the re-examination vision camera 10 checks and inspects the polished area from all angles. Simultaneously, the convective air generated by the combined operation of the suction motor 17 and the blower 20, along with the obstruction of the upper frame 2, front observation plate 3, skin cover 6, and shielding curtain 22, allows the dust generated during grinding to enter the dust collection box 16 through the guide cover 15. The dust is then filtered by the filter plate 19 and collected in the filter drawer 18. During shift handover, the buckle 33 can be rotated to remove the filter drawer 18 from the dust collection box 16 for cleaning or dust recovery. The entire grinding device can be monitored and viewed through the control console 34 to complete the marking, grinding, and re-inspection of stainless steel pipes of different specifications, greatly improving the convenience and efficiency of the grinding device.
