Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel grinding and polishing, specifically to a device for corrosion-resistant treatment of steel component surfaces. Background Technology

[0002] Polishing steel components can improve their corrosion resistance. Polishing removes burrs, oxide layers, and microscopic scratches from the steel surface, making it smoother and denser. This reduces the adhesion points of corrosive media and slows down corrosion spread. For example, the dense passivation film formed after polishing the inner holes of stainless steel can significantly enhance corrosion resistance and extend service life. Polishing can be classified into mechanical polishing and electrolytic polishing based on the process. Mechanical polishing uses polishing tools such as belt sanders and wool wheels to quickly remove defects from the surface of steel components, followed by subsequent treatments (such as passivation) to obtain durable corrosion protection.

[0003] Chinese patent CN222021361U discloses a stainless steel corrosion-resistant polishing device, including a worktable. A motor is fixedly installed on one side of the top of the worktable. A support plate is fixedly connected to the top of the worktable adjacent to the motor. A rotating rod is rotatably connected to the support plate at the output end of the motor. A mounting plate is fixedly connected to one side of the rotating rod. A lead screw is rotatably connected to the middle of the side wall of the mounting plate. A moving block is threaded to the outer wall of the lead screw. Symmetrically arranged limiting rods are fixedly connected to the side wall of the mounting plate at the position of the moving block. Symmetrically arranged upright blocks are fixedly connected to the outer wall of each moving block. A first connecting rod is fixedly connected between each upright block. A linkage block is rotatably connected to the outer wall of each first connecting rod. The beneficial effects of this utility model are: it is convenient to operate, and the movement distance of each polishing block is highly uniform, with less restriction.

[0004] However, this utility model can only polish the inner surface of the steel pipe, and cannot polish the outer surface of the steel pipe.

[0005] Therefore, this utility model proposes a new technical solution to solve the problem that only the inner surface of the steel pipe can be polished. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel component surface corrosion-resistant treatment device, which aims to achieve the technical effect of polishing the inner and outer surfaces of the steel pipe at the same time.

[0007] A corrosion-resistant treatment device for steel components includes a base, a clamping structure disposed on the base, and a polishing structure disposed on the base.

[0008] The clamping structure includes a slide and two mounting seats. The slide is slidably connected to the top of the base. The two mounting seats are symmetrically arranged from left to right, with one slidably connected to the top of the slide and the other fixed to the top of the slide. Two clamping plates symmetrically arranged front to back are slidably connected to the top of each of the two mounting seats. The base is provided with a first driving structure for moving the slide left and right. The slide is provided with a second driving structure for moving one of the mounting seats left and right. The mounting seats are provided with a third driving structure for moving the two clamping plates toward each other or in opposite directions.

[0009] The polishing structure includes a vertical plate, an extension plate, a vertical plate, a linkage structure, an outer surface polishing component, and an inner surface polishing component. The vertical plate is fixed to the top of the base and located on the right side of the clamping structure. The extension plate is fixed to the top of the vertical plate and extends horizontally to the left. The vertical plate is fixed to the bottom of the extension plate. The inner surface polishing component includes a first drive shaft and several first grinding blocks. The first drive shaft corresponds to the middle position of two symmetrical clamping plates. The right end of the first drive shaft is rotatably connected to the vertical plate via a bearing. The left end of the first drive shaft extends horizontally to the left between two mounting seats. Several first grinding blocks are arranged in a ring array outside the left end of the first drive shaft. The outer surface polishing component includes a second drive shaft, a gear, a gear ring, a fixed ring, a rotating ring, and several second grinding blocks. The second drive shaft corresponds to the first drive shaft. Directly above the shaft, the right end of the second drive shaft is rotatably connected to the vertical plate via a bearing. The left end of the second drive shaft extends horizontally to the left and passes through the vertical plate, and is rotatably connected to the vertical plate via a bearing. The gear is fixed to the left end of the second drive shaft. The fixed ring is fixed to the bottom end of the vertical plate. The rotating ring is rotatably connected to the inner wall of the fixed ring via a bearing. Both the fixed ring and the rotating ring are sleeved on the outside of the first drive shaft and are concentric and coaxial with the first drive shaft. The left end of the rotating ring passes through the fixed ring. The gear ring is fixedly sleeved on the outside of the left end of the rotating ring and meshes with the gear. Several second grinding blocks are arranged in a ring array on the inner wall of the rotating ring. A gap is maintained between the second grinding blocks and the first grinding blocks for a steel pipe to pass through. The linkage structure is used to drive the first drive shaft and the second drive shaft to rotate simultaneously.

[0010] By adopting the above technical solution, the second drive structure first moves one of the mounting seats laterally left and right, thereby adjusting the distance between the two mounting seats according to the length of the steel pipe, so that both ends of the steel pipe can be clamped by the clamping plates. Then, the steel pipe passes through the inside of the rotating ring, with its outer wall tightly against the second grinding block. As the steel pipe passes through the rotating ring, it is fitted onto the outside of the first drive shaft, with its inner wall tightly against the first grinding block. Next, the third drive structure moves the two clamping plates towards each other, clamping both ends of the steel pipe. Then, the linkage structure drives the first and second drive shafts to rotate simultaneously. The first drive shaft rotates the first grinding block, polishing the inner surface of the steel pipe. The second drive shaft rotates the gear, which in turn rotates the meshing gear ring, which in turn rotates the rotating ring fixedly connected to it. The rotating ring then rotates the second grinding block, polishing the outer surface of the steel pipe. Then, the first drive structure drives the slide to move left and right, thereby driving the steel pipe to move left and right, which can polish and grind the entire inner and outer surfaces of the steel pipe.

[0011] This invention can simultaneously polish and grind the outer and inner surfaces of steel pipes, thus improving work efficiency.

[0012] A further feature of this invention is that the linkage structure includes a drive motor and two transmission wheels. The two transmission wheels are respectively fixedly sleeved on the outside of the first drive shaft and the second drive shaft. The two transmission wheels are connected by a transmission belt. The drive motor is mounted on the upright plate to drive the first drive shaft to rotate.

[0013] By adopting the above technical solution, when it is necessary to drive the first drive shaft and the second drive shaft to rotate simultaneously through the linkage structure, the drive motor is started. The drive motor drives the first drive shaft to rotate. The first drive shaft drives the transmission wheel on it to rotate, which drives another transmission wheel to rotate through a transmission belt, and the other transmission wheel drives the second drive shaft to rotate. Thus, the synchronous rotation of the first drive shaft and the second drive shaft is achieved.

[0014] Further features of this invention: The first driving structure includes a first sliding groove, a first lead screw, a first motor, and a first nut seat. The first sliding groove is located at the top of the base and extends laterally to the left and right. The first lead screw is rotatably connected to the inside of the first sliding groove via a bearing, and its extension direction is consistent with the first sliding groove. The first nut seat is threaded onto the outside of the first lead screw and slides laterally along the first sliding groove. The front and rear outer side walls of the first nut seat are in contact with the groove wall of the first sliding groove. The top of the first nut seat protrudes from the first sliding groove and is fixedly connected to the bottom of the slide. The first motor is mounted on the outer side wall of the base and is used to drive the first lead screw to rotate.

[0015] By adopting the above technical solution, when it is necessary to move the slide block left or right via the first drive structure, the first motor is activated. The first motor drives the first lead screw to rotate. The first lead screw drives the first nut seat on it to move along the first slide groove. The first nut seat drives the slide block, which is fixedly connected to it, to move.

[0016] Further features of this invention: The second driving structure includes a second slide groove, a second lead screw, a second motor, and a second nut seat. The second slide groove is located at the top of the slide block and extends laterally to the left and right. The second lead screw is rotatably connected to the inside of the second slide groove via a bearing, and its extension direction is consistent with the second slide groove. The second nut seat is threaded onto the outside of the second lead screw and slides laterally along the second slide groove. The front and rear outer side walls of the second nut seat are in contact with the groove wall of the second slide groove. The top of the second nut seat protrudes from the second slide groove and is fixedly connected to the bottom of the mounting base. The second motor is mounted on the outer side wall of the slide block and is used to drive the second lead screw to rotate.

[0017] By adopting the above technical solution, when it is necessary to move the mounting base left or right via the second drive structure, the second motor is activated. The second motor drives the second lead screw to rotate. The second lead screw drives the second nut seat on it to move along the second slide groove. The second nut seat drives the mounting base fixedly connected to it to move.

[0018] Further features of this invention: The third drive structure includes a third slide groove, a positive and negative threaded rod, a third motor, and two third nut seats. The third slide groove is located at the top of the mounting base and extends laterally. The positive and negative threaded rod is rotatably connected to the inside of the third slide groove via bearings, and its extension direction is consistent with the third slide groove. The two third nut seats are respectively threaded onto the outside of the positive threaded portion and the negative threaded portion of the positive and negative threaded rod, and both slide left and right along the third slide groove. The left and right outer side walls of the two third nut seats are in contact with the groove wall of the third slide groove. The top ends of the two third nut seats protrude from the third slide groove and are respectively fixedly connected to the bottom ends of the two clamping plates. The third motor is mounted on the outer side wall of the slide base and is used to drive the positive and negative threaded rod to rotate.

[0019] By adopting the above technical solution, when it is necessary to move the two clamping plates towards each other through the third drive structure, the third motor is started. The third motor drives the positive and negative threaded rods to rotate, and the positive and negative threaded rods drive the two third nut seats on them to move towards each other along the third slide groove, thereby moving the two clamping plates towards each other. Similarly, when it is necessary to move the two clamping plates in the opposite direction through the third drive structure, the output shaft of the third motor simply rotates in the opposite direction.

[0020] A further feature of this invention is that the left end of the first drive shaft is fixedly fitted with an installation sleeve by bolts, and several of the first grinding blocks can be detachably connected to the outer wall of the installation sleeve.

[0021] By adopting the above technical solution, when it is necessary to replace the first grinding block, the bolts between the mounting sleeve and the first drive shaft can be removed to remove the mounting sleeve, thereby facilitating the replacement of the first grinding block on the mounting sleeve.

[0022] A further feature of this invention is that an installation ring is inserted inside the rotating ring via bolts, and several second grinding blocks can be detachably connected to the inner wall of the installation ring.

[0023] By adopting the above technical solution, when it is necessary to replace the second grinding block, the bolts between the mounting ring and the rotating ring can be removed, and the mounting ring can be pulled out from the rotating ring, thus facilitating the replacement of the second grinding block on the mounting ring.

[0024] A further feature of this invention is that each of the two symmetrical clamping plates has an arc-shaped clamping piece on one side, and several studs are fixed on the arc-shaped clamping piece. The other end of the stud passes through the clamping plate in a sliding connection manner, and a fastening nut that abuts against the clamping plate is threaded onto the outside of the stud.

[0025] By adopting the above technical solution, the arc-shaped clamp matches the outer wall of the steel pipe, which increases the force-bearing area between the clamp and the steel pipe, thereby improving the stability of the steel pipe. When it is necessary to replace different arc-shaped clamps to adapt to steel pipes of different diameters, simply unscrew the fastening nut and pull the stud out of the clamp.

[0045] The upright plate 14 is fixed to the top of the base 1 and located on the right side of the clamping structure. The extension plate 15 is fixed to the top of the upright plate 14 and extends horizontally to the left. The vertical plate 16 is fixed to the bottom of the extension plate 15.

[0046] The inner surface polishing component includes a first drive shaft 18 and several first grinding blocks 19. The first drive shaft 18 is positioned at the midpoint of two symmetrical clamping plates 4. The right end of the first drive shaft 18 is rotatably connected to the upright plate 14 via a bearing. The left end of the first drive shaft 18 extends horizontally to the left between two mounting seats 3 and is fixedly fitted with a mounting sleeve 20 by bolts. Several first grinding blocks 19 are detachably connected to the outer wall of the mounting sleeve 20 and are arranged in a ring array.

The arc-shaped clamping piece 29 matches the outer wall of the steel pipe, increasing the force-bearing area between the clamping plate 4 and the steel pipe, thereby improving the stability of the steel pipe. When it is necessary to replace different arc-shaped clamping pieces 29 to accommodate steel pipes of different diameters, simply unscrew the fastening nut 17 and remove the stud 30 from the clamping plate 4.

[0050] General working principle:

[0051] First, the second drive structure moves one of the mounting seats 3 laterally left and right, adjusting the distance between the two mounting seats 3 according to the length of the steel pipe, so that both ends of the steel pipe can be clamped by the clamping plates 4. Then, the steel pipe passes through the inside of the mounting ring 27, with the outer wall of the steel pipe tightly fitting against the second grinding block 26. When the steel pipe passes through the inside of the mounting ring 27, it will be sleeved on the outside of the mounting sleeve 20, with the inner wall of the steel pipe tightly fitting against the first grinding block 19. Next, the third drive structure moves the two clamping plates 4 towards each other, clamping both ends of the steel pipe. Then, the linkage structure drives the first drive shaft 18 and the second drive shaft 21 to rotate simultaneously. The first drive shaft 18 drives the mounting sleeve 20 to rotate, and the mounting sleeve 20 drives the first grinding block 19 to rotate, polishing the inner surface of the steel pipe. The second drive shaft 21 drives the gear 22 to rotate, the gear 22 drives the gear ring 23 meshing with it to rotate, and the gear ring 23 drives the rotating ring 25 fixedly connected to it to rotate. The rotating ring 25 drives the mounting ring 27 to rotate, which in turn drives the second polishing block 26 to rotate, polishing the outer surface of the steel pipe. Then, the first driving structure drives the slide block 2 to move left and right, thereby moving the steel pipe left and right, which polishes the entire inner and outer surfaces of the steel pipe.

[0052] The working principle of the linkage structure is as follows: When it is necessary to drive the first drive shaft 18 and the second drive shaft 21 to rotate simultaneously via the linkage structure, the drive motor 31 is started. The drive motor 31 drives the first drive shaft 18 to rotate. The first drive shaft 18 drives the transmission wheel 28 on it to rotate, which drives another transmission wheel 28 to rotate via a transmission belt. The other transmission wheel 28 drives the second drive shaft 21 to rotate. Thus, the synchronous rotation of the first drive shaft 18 and the second drive shaft 21 is achieved.

[0053] The working principle of the first drive structure is as follows: When it is necessary to move the slide 2 left or right through the first drive structure, the first motor 7 is activated. The first motor 7 drives the first lead screw 6 to rotate. The first lead screw 6 drives the first nut seat on it to move along the first slide groove 5. The first nut seat drives the slide 2, which is fixedly connected to it, to move.

[0054] The working principle of the second drive structure is as follows: When it is necessary to move the mounting base 3 left or right via the second drive structure, the second motor 10 is activated. The second motor 10 drives the second lead screw 9 to rotate. The second lead screw 9 drives the second nut seat on it to move along the second slide groove 8. The second nut seat drives the mounting base 3, which is fixedly connected to it, to move.

[0055] The working principle of the third drive structure is as follows: When it is necessary to move the two clamping plates 4 towards each other through the third drive structure, the third motor 13 is started. The third motor 13 drives the positive and negative threaded rods 12 to rotate. The positive and negative threaded rods 12 drive the two third nut seats on them to move towards each other along the third slide groove 11, thereby moving the two clamping plates 4 towards each other. Similarly, when it is necessary to move the two clamping plates 4 in the opposite direction through the third drive structure, the output shaft of the third motor 13 simply rotates in the opposite direction.

[0056] It is worth noting that in actual use, the steel pipe's inner and outer surfaces cannot be polished because both ends are held by the clamping plate 4. In subsequent operations, the steel pipe can be cut off at both ends, or it can be manually polished. Since the clamping plate 4 is relatively narrow, only 3-4 cm wide, the unpolished portion of the steel pipe is also short. Cutting it off would result in a loss that is entirely within acceptable limits. Manual polishing can also be completed very quickly.

[0057] This invention can simultaneously polish and grind the outer and inner surfaces of steel pipes, thus improving work efficiency.

[0058] The replacement process for the first grinding block 19 and the second grinding block 26 in this invention is also simple and convenient. When the first grinding block 19 needs to be replaced, the bolts between the mounting sleeve 20 and the first drive shaft 18 are removed, allowing the mounting sleeve 20 to be removed and thus facilitating the replacement of the first grinding block 19 on the mounting sleeve 20. When the second grinding block 26 needs to be replaced, the bolts between the mounting ring 27 and the rotating ring 25 are removed, allowing the mounting ring 27 to be pulled out of the rotating ring 25 and thus facilitating the replacement of the second grinding block 26 on the mounting ring 27.
