[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] like Figure 1 , 2As shown: A steel ingot grinding device includes a worktable 101. A drive mechanism is provided on the upper part of the worktable 101 to drive four sliders 404 to move. Each of the four sliders 404 is connected to a bearing seat 102. The bearing seats 102 are provided so that a rotating roller 103 can be supported by every two opposing bearing seats 102, and the rotating roller 103 can be prevented from jamming during rotation. The bearing seats 102 are bolted to the upper part of the sliders 404, so that the bearing seats 102 can be easily disassembled and installed when maintenance or replacement is required. The bearing seats 102 are designed as split bearing seats, which facilitates the installation and maintenance of bearings and reduces the impact of installation errors on rotation. The influence of the rotating roller 103 can also reduce the risk of shaft breakage. A rotating roller 103 is rotatably connected to each pair of opposite bearing seats 102. The rotating roller 103 is set so that the two rotating rollers 103 rotate together with the annular abrasive belt 104 set on them to quickly grind the workpiece. The annular abrasive belt 104 is wound on the outer wall of both rotating rollers 103. The annular abrasive belt 104 can not only grind the workpiece quickly, but also be easy to replace quickly after it is worn, and reduce the cost of use. The annular abrasive belt 104 is fixedly connected to the outer wall of the rotating roller 103 by a sol-bonded connection, so that its connection structure is more stable and thus improves the stability of grinding the workpiece.

[0029] like Figure 1 , 2 As shown: One end of each of the two rotating rollers 103 is connected to the output shaft of the first motor 105 via a coupling. The first motor 105 is set up so that it rotates, thereby driving the two rotating rollers 103 to rotate in opposite directions, which can further improve the grinding effect and speed of the workpiece. The first motor 105 is bolted to one side of the support frame, so that the first motor 105 can be quickly disassembled and installed when maintenance or replacement is required. Both support frames are bolted to the corresponding sliders 404. The support frames are set up to support the first motor 105, thereby preventing the output shaft of the first motor 105 from rotating on its own. A clamping mechanism is set on the upper part of the worktable 101. The clamping mechanism is used to clamp the workpiece, thereby preventing the workpiece from not being fully ground during grinding and improving the grinding speed of the workpiece.

[0030] like Figure 1 , 3As shown: The clamping mechanism includes a fixed frame 201 mounted on the upper part of the worktable 101. The fixed frame 201 provides stable support for the components on it. The fixed frame 201 is bolted to the upper part of the worktable 101, allowing for quick assembly and disassembly. This facilitates the disassembly and replacement of the fixed block 203 and its components when maintenance or replacement is required. A telescopic rod 202 is mounted on the upper part of the fixed frame 201. The telescopic rod 202 allows its push rod to move up and down, thereby allowing the components connected to the push rod of the telescopic rod 202 to move up and down accordingly. The telescopic rod 202 is bolted to the upper part of the fixed frame 201, facilitating quick assembly and disassembly of the telescopic rod 202 and its components when maintenance or replacement is required. The telescopic rod 202 can be configured as an electric telescopic rod 202, which can further reduce costs and facilitate control. One end of the push rod of the telescopic rod 202 is connected to a fixing block 203. The fixing block 203 provides support for the pressure plate 204 below it and allows the pressure plate 204 to move up and down. The fixing block 203 is fixedly connected to the lower part of the push rod of the telescopic rod 202, making the connection structure more stable. The pressure plate 204 is set at the lower part of the fixing block 203. The pressure plate 204 is set with an arc-shaped structure. The pressure plate 204 is set with an arc-shaped structure, which can better fit the cylindrical workpiece and further enhance the clamping effect. The pressure plate 204 is fixedly connected to the lower part of the fixing block 203, making the connection structure more stable.

[0031] like Figure 3 , 4As shown: The clamping plate 204 is made of an elastic material, which can be made of low-density polyethylene. This avoids damage to the workpiece and allows for uniform pressure application according to the workpiece specifications, thereby improving the precision and quality of grinding. It also reduces the impact of vibration generated during grinding on the workpiece, further enhancing the stability during grinding. Mounting plates 301 are provided on both sides of the lower part of the clamping plate 204. The mounting plates 301 provide stable support for the components on them. The mounting plates 301 are fixedly connected to the lower part of the clamping plate 204, making the connection structure more stable and further improving the overall structural stability. Multiple support rods 302 are provided between the two mounting plates 301, providing support for the components on them. Multiple guide wheels 303 can be supported and rotated on them. Multiple support rods 302 are fixedly connected between two mounting plates 301, making the connection structure more stable. Multiple guide wheels 303 are rotatably connected to the outer wall of each support rod 302. The multiple guide wheels 303 allow the guide wheels 303 to rotate flexibly with the slight undulations of the workpiece surface, thereby improving the accuracy and consistency of grinding. When the workpiece deviates slightly during grinding, the deformation of the clamping plate 204 can allow the guide wheels 303 to adjust their position in time and continue to maintain the correct guidance of the workpiece. The multiple guide wheels 303 are rotatably connected to the outer wall of the support rod 302 through bearings, thereby further improving the guiding effect of the guide wheels 303.

[0032] like Figure 1 , 2 As shown: The drive mechanism also includes support blocks 401 located at the four corners of the upper part of the worktable 101. The four support blocks 401 provide stable support for the components, further improving the stability of the support structure. The support blocks 401 are fixedly connected to the upper part of the worktable 101, making the connection structure more stable. A bidirectional screw 402 is rotatably connected to two opposing support blocks 401. The bidirectional screw 402 rotates, causing two sliders 404 on it to move towards or away from each other, thus moving the components on them accordingly. Therefore, the two rotating rollers 1... The spacing between 03 can be adjusted according to the diameter of the workpiece, thus making it suitable for grinding cylindrical workpieces of various specifications. The bidirectional screw 402 is rotatably connected to two opposing support blocks 401 through bearings at both ends, so that the bidirectional screw 402 will not jam when rotating, thereby improving its stability during rotation. A guide rod 403 is connected to the other two opposing support blocks 401. The guide rod 403 guides the two sliders 404 when they move, so that each pair of opposing sliders 404 can move synchronously and further improve the stability of the overall structure.

[0033] like Figure 1 , 2 As shown: The guide rod 403 is fixedly connected to two other opposing support blocks 401, thus providing stable support for the guide rod 403 and preventing the guide rod 403 from rotating when the slider 404 moves on it, thereby improving the stability of the slider 404 when sliding on it. Two sliders 404 are threadedly connected to the outer wall of the bidirectional screw 402, allowing the bidirectional screw 402 to rotate and drive the two sliders 404 to move towards or away from each other, thus moving the sliders 404 and their components accordingly. The other two sliders 404 are slidably connected to the outer wall of the guide rod 403, allowing the other two sliders 404 to... Guided by the guide rod 403, one end of the bidirectional screw 402 is connected to the output shaft of the second motor 405 via a coupling. The second motor 405 is set so that the output shaft of the second motor 405 rotates, causing the bidirectional screw 402 to rotate accordingly. The distance between the two rotating rollers 103 can be adjusted according to the diameter of the workpiece. The second motor 405 is bolted to the upper part of the limiting plate, so that the second motor 405 can be supported, thus preventing the output shaft of the second motor 405 from rotating on its own. The limiting plate is fixedly connected to the vertical surface of one side of the worktable 101, so that the limiting plate can be stably supported, thereby improving the stability of the overall structure.

[0034] like Figure 1 As shown: A waste inlet is provided at the upper axis of the worktable 101. This waste inlet allows grinding debris and waste to fall into the collection box 501 for collection, thus preventing pollution of the working environment and enabling waste to be reused. The waste inlet can be created by a cutting machine through the worktable 101, allowing grinding waste to fall into the collection box 501 for collection. The collection box 501 is located below the waste inlet to collect the grinding waste and facilitate its reuse. Storage facilitates subsequent use and avoids environmental pollution. The collection box 501 can be placed directly on the ground for easy storage and retrieval. All four corners of the collection box 501 are bolted with casters, making it easy to pull out and put in, thus further improving convenience. A handle is fixedly connected to one vertical surface of the collection box 501, making it easy to pull out and put in. Support legs are provided at the four corners of the workbench 101, so that the components on it can be stably supported.

[0035] In operation, the operator places the cylindrical steel ingot to be ground between two rotating rollers 103. Then, the second motor 405 is started to quickly adjust the distance between the two rotating rollers 103 according to the diameter of the workpiece. After adjustment, the telescopic rod 202 is opened, causing its push rod to move downwards. At this time, the pressure plate 204 connected to the end of the push rod of the telescopic rod 202 and its multiple guide wheels 303 will press against the outer wall of the workpiece. After adjustment, the output shafts of the two first motors 105 are controlled to rotate in opposite directions, causing the two rotating rollers 103 and their annular abrasive belts 104 to rotate in opposite directions. Combined with the pressure plate 204 above the workpiece and its components, the cylindrical steel ingot can be quickly ground. Therefore, by replacing the external cylindrical grinding machine with the aforementioned components, its operation is simple, its production cost is low, and it can be used without the need for specialized technicians. This reduces initial investment and personnel costs, facilitates maintenance and replacement, saves on later operating costs, and further improves overall production efficiency.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
