Description

Technical Field

[0001] This application relates to the field of polishing apparatus technology, and more specifically, to a polishing apparatus for steel structure processing. Background Technology

[0002] Steel pipe structures can be used in a variety of fields, and surface polishing is a crucial process in their production and processing. Traditional polishing methods mostly rely on manual operation with hand tools, which is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniformity and consistency of polishing. With the development of industrial production, the requirements for the appearance quality and performance of steel structure products are increasing. Existing simple and rough polishing methods can no longer meet market demands. Although some mechanical polishing equipment has greatly improved polishing efficiency, its overall structure is complex and difficult to adapt to the batch polishing needs of steel pipes of different specifications. This can easily lead to problems such as scratches and uneven gloss on the product surface, affecting the overall quality and market competitiveness of the product. In view of this, we propose a polishing device for steel structure processing. Utility Model Content

[0003] 1. Technical problems to be solved The purpose of this application is to provide a polishing device for steel structure processing, which solves the technical problems in the background art mentioned above. It realizes the coordinated operation of automated carriage movement and translation mechanism, reduces manual intervention, and greatly improves production efficiency. The stable structure combined with precise pressure control allows the polishing belt to contact the steel pipe evenly, which greatly improves the surface smoothness and flatness, and achieves the purpose of self-rotation polishing of steel pipe, thus optimizing product quality. It can be adapted to polishing processing of steel pipe with different specifications, and has strong versatility. It also reduces the labor intensity of workers and effectively blocks sparks from splashing by using baffles, thus improving the working environment.

[0004] 2. Technical Solution This application provides a polishing device for steel structure processing, comprising: two parallel guide rails, multiple horizontal plates fixed between the guide rails, multiple support rollers installed between the horizontal plates, steel pipe fittings placed between the two support rollers, a slide frame slidably installed between the guide rails, a translation mechanism installed on one of the guide rails for driving the slide frame to slide along the guide rails, two baffles fixedly installed on the slide frame, and a polishing mechanism and a clamping mechanism installed on the slide frame; The polishing mechanism includes a motor fixed on a slide, two parallel rotating shafts rotatably mounted on the slide, two triangular chain mechanisms drivingly connecting the output shaft of the motor to the two rotating shafts, drive wheels fixed at both ends of the rotating shafts, and a polishing belt drivingly connecting the drive wheels. The clamping mechanism includes a concave seat fixed on a slide, an electric cylinder fixed on the concave seat, a pressure plate fixed to the piston rod of the electric cylinder, and multiple pressure shafts rotatably connected to the pressure plate. Pressure rollers are rotatably mounted at both ends of the pressure shafts and located at the polishing belt.

[0005] By adopting the above technical solution, two guide rails serve as the sliding guide base for the carriage. Multiple horizontal plates are fixed between the guide rails, and multiple parallel support rollers are installed. The support rollers between adjacent pairs can accommodate steel pipes of different diameters and lengths. A polishing mechanism and a pressing mechanism are installed on the carriage. A motor drives two triangular chain mechanisms to rotate, causing two rotating shafts to drive the drive wheels at their ends, resulting in high-speed movement of the polishing belt to grind and polish the surface of the steel pipe. Meanwhile, an electric cylinder fixedly installed on the concave seat drives the pressure plate downward, allowing the pressure roller at the end of the pressure shaft to press the polishing belt and evenly transmit pressure to the steel pipe. This allows the steel pipe to be polished efficiently under pressure while simultaneously achieving rotational capability, resulting in a circumferential polishing effect. Combined with the sliding of the carriage along the guide rails, this achieves efficient overall polishing of the steel pipe. Two baffles are fixedly installed on the carriage to effectively prevent sparks from scattering during polishing, providing a good and safe processing environment.

[0006] Optionally, the support roller includes two rows of multiple rotating blocks, which are respectively fixed on the horizontal plates located at both ends of the guide rail. Each row of rotating blocks is equidistantly arranged, and multiple parallel rotating rods are rotatably installed between the two rows of rotating blocks. Multiple support wheels are equidistantly arranged on the rotating rods along the axial direction.

[0007] By adopting the above technical solution, the two rows of rotating blocks are set one-to-one, which can be used to rotatably install multiple parallel and equally spaced rotating rods. Each rotating rod is equidistantly equipped with multiple support wheels along the axial direction, so that the support force is more evenly distributed, avoiding deformation of the steel pipe due to excessive local stress. At the same time, the steel pipe can achieve the effect of self-rotation while being supported.

[0008] Optionally, the carriage includes a slide block that slides on a guide rail, and two parallel concave frames are fixedly connected between the slide blocks. The baffle is fixed between the concave frames and is located outside the drive wheel.

[0009] By adopting the above technical solution, the drive wheel can be positioned in the middle of the two baffles by installing two baffles on the carriage. This allows the sparks generated during the polishing of the steel pipe by the polishing belt to be effectively blocked and processed by the baffles, thus providing a good and safe processing environment.

[0010] Optionally, the triangular chain mechanism includes a chain and three sprockets. The output shaft of the motor is connected to one sprocket for transmission, and the other two sprockets are respectively fixedly sleeved to a rotating shaft.

[0011] By adopting the above technical solution, the output shaft of motor one is connected to a sprocket drive to ensure effective power transmission. The other two sprockets are respectively fixedly sleeved with a rotating shaft, so that the two rotating shafts can rotate synchronously under the drive of motor one, thereby driving the polishing belt to run stably.

[0012] Optionally, multiple pressure shafts are arranged in parallel and all intersect the pressure plate perpendicularly, and the pressure roller is located in the middle of the two support rollers.

[0013] By adopting the above technical solution, multiple pressure shafts are set in parallel and perpendicular to the pressure plate, so that the pressure can be evenly distributed on the surface of the steel pipe through the polishing belt, avoiding the difference in polishing effect caused by uneven pressure. In addition, the pressure roller is set in the middle of the two support rollers, which can ensure that the polishing belt has good contact with the surface of the steel pipe, thus improving the efficiency and quality of polishing.

[0014] Optionally, the translation mechanism includes a second motor and support blocks fixed to both ends of a guide rail. The second motor is fixed to a support block, and the output shaft of the second motor is driven by a lead screw. The lead screw is rotatably connected to two support blocks, and the lead screw is threadedly connected to a screw block. The screw block is fixedly connected to the slide.

[0015] By adopting the above technical solution, the output shaft of motor 2 drives the lead screw to rotate, and the rotation of the lead screw drives the screw block to move, thereby realizing the smooth sliding of the carriage along the guide rail and realizing the automated polishing operation of steel pipe fittings.

[0016] 3. Beneficial effects One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. The structure employing two parallel guide rails, along with a horizontal plate and support rollers, provides stable support and positioning for the steel pipe fittings, ensuring their smooth operation during polishing. The carriage can slide along the guide rails, and combined with a translation mechanism, it achieves automated movement, improving the continuity and efficiency of processing. 2. The motor drives the drive wheels on two rotating shafts through a triangular chain mechanism, which in turn drives the polishing belt. The transmission method is stable and reliable, and it can ensure uniform tension of the polishing belt, resulting in a more ideal polishing effect. The electric cylinder pushes the pressure plate, which carries multiple pressure shafts and pressure rollers downward. The pressure rollers are located in the middle of the support rollers, which can apply appropriate pressure to the steel pipes during polishing. The pressure can be adjusted according to different specifications of steel pipes, which has strong versatility and adaptability, enhances the polishing effect, ensures uniform pressure distribution, and avoids damage caused by local overpressure. At the same time, it forces the steel pipes to rotate along the support rollers to complete the circumferential polishing effect. With the help of the automated carriage movement and translation mechanism, manual intervention is reduced, and the polishing operation of steel pipes can be carried out quickly and continuously, which greatly improves production efficiency. 3. The baffle design effectively avoids sparks during polishing, providing a good and safe processing environment. Attached Figure Description

[0018] The present application will be further described in detail below with reference to the accompanying drawings. Reference Figures 1 to 4 This application provides a polishing device for steel structure processing, comprising: two parallel guide rails 1, a plurality of horizontal plates 2 fixed between the guide rails 1, a plurality of support rollers 3 installed between the horizontal plates 2, a steel pipe 9 placed between the two support rollers 3, a slide 4 slidably installed between the guide rails 1, a translation mechanism 8 installed on one guide rail 1 for driving the slide 4 to slide along the guide rail 1, two baffles 7 fixedly installed on the slide 4, and a polishing mechanism 5 and a pressing mechanism 6 installed on the slide 4; The polishing mechanism 5 includes a motor 51 fixed on the slide 4. Two parallel rotating shafts 53 are rotatably mounted on the slide 4. The output shaft of the motor 51 is connected to the two rotating shafts 53 by two triangular chain mechanisms 52. Both ends of the rotating shafts 53 are fixed with drive wheels 55. A polishing belt 56 is connected between the drive wheels 55. The clamping mechanism 6 includes a concave seat 61 fixed on the slide 4. An electric cylinder 62 is fixed on the concave seat 61. A pressure plate 63 is fixed to the piston rod of the electric cylinder 62. Multiple pressure shafts 64 are rotatably connected to the pressure plate 63. Pressure rollers 65 rotate at both ends of the pressure shafts 64 and are located at the polishing belt 56. The slide 4 is guided by two guide rails 1. Multiple horizontal plates 2 are fixed between the guide rails 1. Multiple parallel support rollers 3 are installed. The support rollers 3 can accommodate steel pipes 9 of different diameters and lengths. The slide 4 is equipped with a polishing mechanism 5 and a clamping mechanism 6. Two triangular chain mechanisms 52 are driven to rotate by a motor 51, so that the two... A rotating shaft 53 drives the drive wheel 55 at its end to rotate, causing the polishing belt 56 to move at high speed, grinding and polishing the surface of the steel pipe fitting 9. Meanwhile, the electric cylinder 62, fixedly mounted on the concave seat 61, drives the pressure plate 63 to move downwards, allowing the pressure roller 65 at the end of the pressure shaft 64 to press the polishing belt 56 and evenly transmit pressure to the steel pipe fitting 9. This allows the steel pipe fitting 9 to rotate while being polished under pressure, achieving a circumferential polishing effect. Combined with the sliding of the carriage 4 along the guide rail 1, this achieves efficient overall polishing of the steel pipe fitting 9. Two baffles 7 are fixedly installed on the carriage 4 to effectively prevent sparks from flying during polishing, providing a good and safe processing environment.

[0019] Reference Figure 1 and Figure 2 The support roller 3 includes two rows of multiple rotating blocks 31, which are fixed on the horizontal plates 2 located at both ends of the guide rail 1. Each row of rotating blocks 31 is equidistantly arranged, and multiple parallel rotating rods 32 are rotatably installed between the two rows of rotating blocks 31. Multiple support wheels 33 are equidistantly arranged along the axial direction of the rotating rods 32. The two rows of rotating blocks 31 are arranged one-to-one, which can be used to rotatably install multiple parallel and equidistantly arranged rotating rods 32. Each rotating rod 32 is equidistantly arranged along the axial direction of multiple support wheels 33, so that the supporting force is more evenly distributed, avoiding deformation of the steel pipe 9 due to excessive local force, and the steel pipe 9 can achieve a self-rotation effect while being supported.

[0020] Reference Figure 1 and Figure 3 The slide 4 includes a slide seat 41 that slides on the guide rail 1. Two parallel concave frames 42 are fixedly connected between the slide seats 41. A baffle 7 is fixed between the concave frames 42 and is located outside the drive wheel 55. By installing two baffles 7 on the slide 4, the drive wheel 55 can be positioned in the middle of the two baffles 7, so that the sparks generated by the polishing belt 56 during the polishing of the steel pipe 9 can be smoothly blocked and processed by the baffles 7, thereby providing a good and safe processing environment.

[0021] Reference Figure 3 and Figure 4The triangular chain mechanism 52 includes a chain and three sprockets. The output shaft of motor 51 is connected to one sprocket for transmission, and the other two sprockets are fixedly sleeved with a rotating shaft 53. The connection between the output shaft of motor 51 and one sprocket ensures effective power transmission. The fixed sleeves of the other two sprockets with the rotating shaft 53 enable the two rotating shafts 53 to rotate synchronously under the drive of motor 51, thereby driving the polishing belt 56 to run stably.

[0022] Reference Figure 3 and Figure 4 Multiple pressure shafts 64 are arranged in parallel and intersect the pressure plate 63 perpendicularly. The pressure roller 65 is located in the middle of the two support rollers 3. The arrangement of multiple pressure shafts 64 in parallel and perpendicular to the pressure plate 63 allows the pressure to be evenly distributed on the surface of the steel pipe 9 through the polishing belt 56, avoiding differences in polishing effect caused by uneven pressure. Furthermore, the location of the pressure roller 65 in the middle of the two support rollers 3 ensures good contact between the polishing belt 56 and the surface of the steel pipe 9, improving the efficiency and quality of polishing.

[0023] Reference Figure 1 and Figure 2 The translation mechanism 8 includes a second motor 81 and support blocks 82 fixed at both ends of a guide rail 1. The second motor 81 is fixed on a support block 82. The output shaft of the second motor 81 is driven by a lead screw 84. The lead screw 84 is rotatably connected to the two support blocks 82. The lead screw 84 is threadedly connected to a screw block 83. The screw block 83 is fixedly connected to the slide 4. The output shaft of the second motor 81 drives the lead screw 84 to rotate. The rotation of the lead screw 84 drives the screw block 83 to move, thereby realizing the smooth sliding of the slide 4 along the guide rail 1 and realizing the automated polishing operation of the steel pipe 9.

[0024] Working principle: When polishing steel pipe fittings 9, the steel pipe fittings 9 to be polished are first placed between two support rollers 3, and multiple steel pipe fittings 9 are laid simultaneously using multiple support rollers 3. The support rollers 3 support the steel pipe fittings 9 together through multiple support wheels 33 set on the rotating rod 32, keeping the steel pipe fittings 9 in a horizontal state. The output shaft of motor 51 drives two parallel rotating shafts 53 to rotate through two triangular chain mechanisms 52. The drive wheels 55 fixed at both ends of the rotating shafts 53 drive the polishing belt 56 to rotate at high speed, polishing the surface of the steel pipe fittings 9. At the same time, the electric cylinder 62 extends the piston rod, pushing the pressure plate 63 to move downward. Multiple pressure shafts 64 are moved downwards, and the polishing belt 56 is pressed by the pressure rollers 65 at the ends of the pressure shafts 64, so that the polishing belt 56 is pressed tightly against the steel pipe fitting 9, giving the steel pipe fitting 9 a certain pressure. This enables the steel pipe fitting 9 to rotate along the support wheel 33 during the polishing process, achieving a circumferential polishing effect for the steel pipe fitting 9 and enhancing the polishing effect. Due to the action of the two baffles 7, the spark particles generated during polishing can be prevented from splashing around, thus providing a safe construction environment. Then, the output shaft of the motor 2 81 drives the lead screw 84 to rotate, so that the screw block 83 drives the slide 4 to slide smoothly along the guide rail 1, thereby completing the polishing treatment of the entire surface of the steel pipe fitting 9.
