High-precision steel member polishing equipment

Abstract

This utility model relates to the field of grinding equipment technology, specifically a high-precision steel component grinding equipment, including a frame. A cylinder is fixedly connected to the top surface of the frame. Under the limiting action of the limiting groove, when the lever is moved by the limiting groove, the lever can only slide along the limiting groove. This causes the lever to drive the slider to slide within the fixed ring, and the slider gradually moves towards the axis of the fixed ring. As a result, the slider gradually extends out of the fixed ring and drives the contact wheel to gradually contact the steel pipe to be ground. When the rotating ring rotates, it causes the three sets of circumferentially arrayed sliders to simultaneously drive the contact wheel to contact the surface of the steel pipe through the above method. Furthermore, the contact wheels in the symmetrically arranged positioning plate ensure that both ends of the steel pipe are simultaneously contacted by the contact wheel and positioned at the center of the positioning plate. This avoids the axis of the steel pipe from shifting, which would result in uneven grinding and thus makes the grinding of the steel pipe more precise.

Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically a high-precision steel component grinding equipment. Background Technology

[0002] Steel component grinding equipment refers to tools or machines used for deburring, polishing, or weld treatment of metal surfaces. These mainly include handheld angle grinders, stationary grinding wheels, and automated grinding systems. Their core principle is to remove material through high-speed friction of abrasive particles. Safety features and dust collection devices are also included to ensure efficiency and safety. Steel pipes, as steel components, also require grinding equipment to achieve a smoother surface.

[0003] However, when grinding steel pipes, the pipes must first be fixed before the surface is ground. The existing fixing method uses clamps to fix both ends of the pipe before grinding. However, in order to accommodate steel pipes of different lengths and sizes, the clamps are generally movable. This means that the axial centers of the two ends of the pipe cannot be accurately aligned during the adjustment and fixing of the pipe. If the axial centers of the two ends of the pipe deviate, the contact point between the grinding wheel and the pipe will be misaligned, resulting in insufficient grinding precision.

[0004] In view of this, we propose a high-precision steel component grinding equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a high-precision steel component grinding equipment, which solves the problem of decreased precision caused by axial offset during steel pipe grinding.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-precision steel component grinding device includes a frame, a cylinder fixedly connected to the top surface of the frame, a lifting platform slidably connected to the inner side of the frame, a grinding machine mounted on the bottom surface of the lifting platform, and the output shaft of the cylinder fixedly connected to the top surface of the lifting platform. It also includes a positioning component to prevent uneven grinding caused by axial misalignment at both ends of the steel pipe during grinding of tubular steel structures. The positioning component includes a limiting plate fixedly connected to the inner side of the frame, a positioning disc slidably connected to the inner side of the limiting plate, a fixing ring fixedly connected to the inner side of the positioning disc, a fixing column fixedly connected to the top surface of the fixing ring, a telescopic rod slidably connected to the inner side of the fixing column, a slider fixedly connected to the bottom end of the telescopic rod, and an abutment wheel mounted on the inner side of the slider.

[0008] Preferably, an anti-detachment plate is fixedly connected to one end of the telescopic rod located inside the fixed column, and a spring is sleeved on the outside of the telescopic rod. One end of the spring is fixedly connected to the bottom surface of the anti-detachment plate, and the other end of the spring is fixedly connected to the inside of the fixed column.

[0009] Preferably, a lever is fixedly connected to the surface of the slider, and a limiting groove is formed on the surface of the fixing ring, through which the lever passes.

[0010] Preferably, a rotating ring is rotatably connected to the inner side of the positioning disk, and a toggle groove is formed on the surface of the rotating ring. The toggle rod passes through the limiting groove and is inserted into the inner side of the toggle groove.

[0011] Preferably, a trigger rod is fixedly connected to the side of the rotating ring, and a movable groove is provided on the side of the positioning disk, through which the trigger rod passes.

[0012] Preferably, the surface of the limiting plate is provided with a guide groove, and the trigger rod passes through the movable groove and is inserted into the inner side of the guide groove.

[0013] Preferably, a ring is fixedly connected to the surface of the limiting plate, an mounting plate is fixedly connected to the inner side of the ring, a second cylinder is fixedly connected to the surface of the mounting plate, and the output shaft of the second cylinder is fixedly connected to the surface of the positioning plate.

[0014] By employing the above technical solution, this utility model provides a high-precision steel component grinding device. It possesses at least the following beneficial effects:

[0015] 1. This utility model, through the limiting action of the limiting groove, ensures that when the lever is moved by the limiting groove, the lever can only slide along the limiting groove. This causes the lever to drive the slider to slide within the fixed ring, and the slider gradually moves towards the axis of the fixed ring. As a result, the slider gradually extends out of the fixed ring and drives the contact wheel to gradually contact the steel pipe to be ground. When the rotating ring rotates, the three sets of circumferentially arrayed sliders simultaneously drive the contact wheel to contact the surface of the steel pipe through the above method. Furthermore, the contact wheels in the symmetrically arranged positioning plate ensure that both ends of the steel pipe are simultaneously contacted by the contact wheel and positioned at the center of the positioning plate. This avoids the axis of the steel pipe from shifting, which would result in uneven grinding and thus makes the grinding of the steel pipe more precise.

[0016] 2. In this utility model, when the contact wheel gradually contacts the steel pipe to be ground under the transmission effect of the rotating ring, the contact wheel can also prevent the steel pipe from getting stuck during grinding. At the same time, after the middle section of the steel pipe is ground, the second cylinder can be started to gradually release the steel pipe and pull the steel pipe. Then, the second cylinder can make the contact wheel reposition the steel pipe. At the same time, it can also ensure that the axis is the same as before grinding, avoiding the inaccuracy of the axis position caused by some clamps fixing the steel pipe and then disassembling it.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A high-precision steel component grinding equipment, such as Figure 1 - Figure 5As shown, the system includes a frame 1, with a cylinder 3 fixedly connected to the top surface of the frame 1. A lifting platform 4 is slidably connected to the inner side of the frame 1, and a grinder 5 is installed on the bottom surface of the lifting platform 4. The output shaft of the cylinder 3 is fixedly connected to the top surface of the lifting platform 4. It also includes a positioning component 2, used to prevent uneven grinding caused by axial misalignment at both ends of the tubular steel structure during grinding. The positioning component 2 includes a limiting plate 21, which is fixedly connected to the inner side of the frame 1. A positioning disc 22 is slidably connected to the inner side of the limiting plate 21. A fixing ring 23 is fixedly connected to the inner side of the positioning disc 22. A fixing post 24 is fixedly connected to the top surface of the fixing ring 23. A telescopic rod 25 is slidably connected to the inner side of the fixing post 24, and the bottom end of the telescopic rod 25 is fixedly connected to... There is a slider 27, and an abutment wheel 29 is provided on the inner side of the slider 27. Since the lever 210 passes through the limiting groove 219 and is also inserted into the actuating groove 212 at the same time, the limiting groove 219 will limit the lever 210. At the same time, when the rotating ring 211 rotates, the actuating groove 212 will actuate the lever 210. Under the limiting action of the limiting groove 219, when the actuating groove 212 actuates the lever 210, the lever 210 can only slide along the limiting groove 219. This causes the lever 210 to drive the slider 27 to slide within the fixed ring 23. The slider 27 will gradually move towards the axis of the fixed ring 23, causing the slider 27 to gradually extend out of the fixed ring 23 and drive the abutment wheel 29 to gradually contact the steel pipe to be ground. An anti-detachment plate 26 is fixedly connected to one end of the telescopic rod 25 located inside the fixed post 24. A spring 28 is sleeved on the outside of the telescopic rod 25. One end of the spring 28 is fixedly connected to the bottom surface of the anti-detachment plate 26, and the other end of the spring 28 is fixedly connected to the inside of the fixed post 24. A lever 210 is fixedly connected to the surface of the slider 27. A limiting groove 219 is formed on the surface of the fixed ring 23, and the lever 210 passes through the limiting groove 219 formed on the surface of the fixed ring 23. A rotating ring 211 is rotatably connected to the inner side of the positioning disk 22. A steel pipe is inserted into the positioning disk 22, and then the cylinder 218 is activated. The output end of the cylinder 218 pulls the positioning disk 22 closer to the ring 216. As the positioning disk 22 moves closer to the ring 216, the positioning disk 22 will drive the fixed ring 23 and the rotating ring 211 on its inner side to move together. The rotating ring 211 has a toggle groove 212 on its surface. The lever 210 passes through the limiting groove 219 and inserts into the inside of the toggle groove 212. The trigger rod 213 slides in the movable groove 214 without causing motion interference. The trigger rod 213 will toggle the rotating ring 211 to rotate. When the rotating ring 211 rotates due to the force of the trigger rod 213, it will drive the toggle groove 212 on its surface to rotate together.A trigger rod 213 is fixedly connected to the side of the rotating ring 211. A movable groove 214 is provided on the side of the positioning disk 22. When the rotating ring 211 moves with the positioning disk 22, it drives the trigger rod 213 fixedly connected to its side to move as well. Because the trigger rod 213 is inserted into the guide groove 215, it gradually slides along the inclined surface of the guide groove 215 during movement, allowing it to slide within the movable groove 214 without causing motion interference. The trigger rod 213 passes through the movable groove 214. A guide groove 215 is provided on the surface of the limiting plate 21. The trigger rod 213 passes through the movable groove 214 and inserts into the inner side of the guide groove 215. A ring 216 is fixedly connected to the surface of the limiting plate 21. A mounting plate 217 is fixedly connected to the inner side of the ring 216. A cylinder 218 is fixedly connected to the surface of the mounting plate 217. The output shaft of the cylinder 218 is fixedly connected to the surface of the positioning disk 22.

[0026] In use, the high-precision steel component grinding equipment of this utility model first passes the tubular steel structure to be ground through one end of the frame 1 and inserts the steel pipe into the positioning plate 22. Then, the cylinder 218 is activated, causing its output end to pull the positioning plate 22 towards the ring 216. As the positioning plate 22 moves towards the ring 216, it will drive the inner fixed ring 23 and rotating ring 211 to move together. The rotating ring 211 will move along with the positioning plate 22. The trigger rod 213, which is fixedly connected to the moving side, moves together. Because the trigger rod 213 is inserted into the guide groove 215, it gradually slides along the inclined surface of the guide groove 215 during movement, allowing it to slide within the movable groove 214 without causing motion interference. The trigger rod 213 also actuates the rotating ring 211. When the rotating ring 211 rotates due to the actuation force of the trigger rod 213, it drives the actuation groove 212 on its surface to rotate as well. Since the lever 210 passes through the limit... The slot 219 is also inserted into the actuating slot 212, so that the limiting slot 219 limits the lever 210. At the same time, as the rotating ring 211 rotates, the actuating slot 212 actuates the lever 210. Under the limiting action of the limiting slot 219, when the actuating slot 212 actuates the lever 210, the lever 210 can only slide along the limiting slot 219. This causes the lever 210 to drive the slider 27 to slide within the fixed ring 23, and the slider 27 will gradually move towards the axis of the fixed ring 23, thus causing the slider 27 to... The rotating ring 211 gradually extends from the fixed ring 23, causing the contact wheel 29 to gradually contact the steel pipe to be polished. When the rotating ring 211 rotates, it causes the three sets of circumferentially arrayed sliders 27 to simultaneously drive the contact wheel 29 to contact the surface of the steel pipe. Furthermore, through the contact wheel 29 in the symmetrically arranged positioning disk 22, it can be ensured that both ends of the steel pipe are simultaneously contacted by the contact wheel 29 and positioned at the center of the positioning disk 22. This avoids the axial displacement of both ends of the steel pipe, which would lead to uneven polishing in the subsequent process, thus making the polishing of the steel pipe more precise.

[0027] Furthermore, as the contact wheel 29 gradually contacts the steel pipe to be ground under the transmission effect of the rotating ring 211, the contact wheel 29 can also prevent the steel pipe from getting stuck during grinding. After the middle section of the steel pipe is ground, the cylinder 218 can be started to gradually release the steel pipe and pull it out. Then, the contact wheel 29 can be repositioned by the cylinder 218, which can also ensure that the axis is the same as before grinding, and avoid the inaccuracy of the axis position caused by some clamps fixing the steel pipe and then disassembling it.
