Description

Technical Field

[0001] This utility model relates to the field of high-efficiency rolling mill rolls, specifically to a high-efficiency rolling mill roll repair and grinding machine. Background Technology

[0002] High-efficiency rolls, as crucial tools and consumables in steel rolling mills, directly impact the efficiency and product quality of steel rolling production lines. Heavy Industry Technology often employs advanced materials and processes in the design and manufacture of high-efficiency rolls to improve rolling efficiency and precision. With the continuous development of Heavy Industry Technology, the steel rolling industry is gradually upgrading. The promotion and application of high-efficiency rolls is a significant manifestation of Heavy Industry Technology's presence in the steel rolling field, contributing to improved production levels and competitiveness across the entire industry. Therefore, the repair of high-efficiency rolls requires the use of high-efficiency roll repair and grinding machines. These machines are specifically designed for repairing and grinding roll surfaces. Through a unique mechanical structure and control system, they achieve precise grinding and repair of roll surfaces, thereby improving roll lifespan and processing efficiency.

[0003] A search revealed a high-efficiency roll repair and grinding machine (publication number CN222078775U). Specifically, the machine discloses a high-efficiency roll repair and grinding machine, including a base. A machine tool is fixedly connected to the top of the base, and a roll is mounted on the machine tool. A fixed frame is mounted on the top of the base, and a moving mechanism is located within the inner cavity of the fixed frame. A mounting plate is fixedly connected to the bottom of the moving mechanism, and a grinding mechanism is fixedly connected to the bottom of the mounting plate. The grinding mechanism includes a servo motor fixedly connected to the bottom of the mounting plate, and a drive shaft is fixedly connected to the output shaft of the servo motor. During repair, the machine tool drives the roll to rotate, allowing the grinding block to grind the roll. The servo motor drives a cam to press against a connecting plate, and under the elastic support of a spring, the grinding block repeatedly moves left and right. The overall structure achieves the goal of high-efficiency grinding, eliminating the need for multiple grinding operations to eliminate the ring marks formed during a single grinding operation.

[0004] Existing high-efficiency roll repair and grinding machines, due to the need for high-precision repair of high-efficiency rolls, lack real-time scanning and feedback functions. This makes it impossible to accurately identify the wear areas and grinding paths on the roll surface, easily leading to missed grinding or over-grinding, resulting in unstable repair quality. Furthermore, the high-efficiency roll repair and grinding machine in the aforementioned comparative case also lacks real-time scanning and feedback functions. Under such circumstances, long-term use will also lead to the high-efficiency roll repair and grinding machine relying on manual inspection and adjustment, which will result in a long repair process and affect production efficiency.

[0005] Therefore, it is necessary to invent a high-efficiency roll repair and grinding machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency roll repair and grinding machine. Through a drive display controller, infrared scanner, grinding column, robotic arm, grinding seat, grinding head, and pressure sensor, this high-efficiency roll repair and grinding machine possesses real-time scanning and feedback functions. The pressure sensor monitors the contact pressure between the grinding head and the roll surface in real time, ensuring uniform and appropriate pressure to avoid overpressure causing damage to the roll surface or underpressure leading to poor repair results, thus improving repair accuracy. Then, the infrared scanner scans the roll surface in real time, accurately identifying wear areas and grinding paths to avoid missed or over-grinding, ensuring consistent repair quality. This collaborative operation automatically plans and adjusts the grinding path, reducing manual intervention, shortening the repair cycle, and improving production efficiency. This design significantly improves the repair accuracy, efficiency, ease of operation, and intelligence level of the high-efficiency roll repair and grinding machine, reduces reliance on manual labor, and shortens the repair process. It addresses the problem in existing high-efficiency roll repair and grinding machines that, due to the high precision required for roll repair, lack real-time scanning and feedback functions, making it impossible to accurately identify wear areas and grinding paths on the roll surface. This can easily lead to missed or over-grinding, resulting in unstable repair quality. Furthermore, the high-efficiency roll repair and grinding machine in the aforementioned comparative case also lacks real-time scanning and feedback functions. Long-term use of this would lead to reliance on manual inspection and adjustment, resulting in a lengthy repair process and impacting production efficiency.

[0018] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0019] 1. This utility model includes a drive display controller, an infrared scanner, a grinding column, a robotic arm, a grinding base, a grinding head, and a pressure sensor. During the grinding process, the pressure sensor inside the grinding disc transmits the pressure at the contact point between the grinding head and the outside of the high-efficiency roll body in real time to the drive display controller via an electrical connection. Then, driven by a second telescopic cylinder, the infrared scanner synchronously follows the grinding head, scanning the grinding trajectory on the outside of the high-efficiency roll body, and also transmits the data to the drive display controller via an electrical connection. This eliminates the need for manual control of the grinding path by the operator.

The high-efficiency roll body achieves self-adaptive capabilities, and this design enables the high-efficiency roll repair and grinding machine to have real-time scanning and feedback functions. Pressure sensors monitor the contact pressure between the grinding head and the roll surface in real time, ensuring that the pressure is uniform and moderate, avoiding overpressure that could damage the roll surface or underpressure that could lead to poor repair results, thus improving repair accuracy. Then, an infrared scanner scans the roll surface in real time, accurately identifying the wear area and grinding path, avoiding missed grinding or over-grinding, and ensuring consistent repair quality. This collaborative work automatically plans and adjusts the grinding path, reducing manual intervention, shortening the repair cycle, and improving production efficiency. This design significantly improves the repair accuracy, efficiency, ease of operation, and intelligence level of the high-efficiency roll repair and grinding machine, reducing reliance on manual labor and shortening the repair process.

[0020] 2. This utility model includes a grinding machine, a rear clamping table, a roller sleeve, a drive motor, a front jaw plate, a contact screw, clamping claws, and a high-efficiency roll body. When using this high-efficiency roll repair grinding machine, since the high-efficiency roll bodies to be repaired vary in size and length, the position of the rear clamping table can be adjusted via the first electric slide rail. One end of the high-efficiency roll body is clamped by the clamping claws of the front jaw plate, while the other end is fitted into the roller sleeve of the rear clamping table. This allows the high-efficiency roll repair grinding machine to handle high-efficiency roll bodies of different sizes and lengths. By adjusting the position of the rear clamping table, it can flexibly adapt to rolls of various sizes without changing equipment or making complex adjustments. Moreover, because the high-efficiency roll body is firmly clamped and fitted, the stability and positional accuracy of the roll body are ensured during the grinding process. This helps to reduce grinding errors caused by the shaking or movement of the high-efficiency roll body, thereby improving the precision and quality of grinding. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figure 1-7 The high-efficiency roll repair and grinding machine shown includes a grinding machine base 1, which is the main body for supporting the grinding machine components;

[0033] Grinding machine tool 2 is set above grinding machine base 1 and is used to place rollers. A drive display controller 14 is fixedly installed on the outside of grinding machine tool 2. An upper scanning stage 15 is fixedly installed on the top of grinding machine tool 2. A sliding groove 16 is opened inside the upper scanning stage 15. A sliding block 17 is slidably connected inside the sliding groove 16. A push block 18 is fixedly installed at the bottom of the sliding block 17. An infrared scanner 19 is fixedly installed on the outside of the push block 18. A second telescopic cylinder 20 is set above the upper scanning stage 15. The front end of the second telescopic cylinder 20 is fixedly connected to the sliding block 17.

[0034] The second electric slide rail 21 is located outside the grinding machine tool 2 and is used to slide and connect the second electric slide sleeve 22. An arm seat 23 is fixedly installed on the outside of the second electric slide sleeve 22. A servo motor 24 is fixedly installed at the bottom of the arm seat 23. A grinding column 25 is rotatably connected to the output end of the servo motor 24. A hydraulic cylinder 26 is embedded inside the grinding column 25. A robotic arm 27 is fixedly installed on the top of the hydraulic cylinder 26.

[0035] The grinding base 28 is located at the front end of the robotic arm 27 and is used to grind the roll. A micro motor 29 is fixedly installed on the outside of the grinding base 28. The output end of the micro motor 29 is rotatably connected to a fixed rod 30. A grinding disc 31 is fixedly installed on the other end of the fixed rod 30. A grinding head 32 is fixedly installed on the outside of the grinding disc 31. A pressure sensor 33 is installed inside the grinding disc 31. During the grinding process, the pressure sensor 33 inside the grinding disc 31 will transmit the pressure of the current contact part between the grinding head 32 and the outside of the high-efficiency roll body 13 to the drive display controller 14 in real time through wire connection.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the grinding machine tool 2 is internally equipped with a first electric slide rail 3, and externally connected to the first electric slide rail 3 is a first electric slide sleeve 4. Externally mounted on the first electric slide sleeve 4 is a rear clamping platform 5. The position of the rear clamping platform 5 can be adjusted by the first electric slide rail 3, so that one end of the high-efficiency roll body 13 is clamped by the clamping jaws 12 of the front jaw plate 10, and the other end is fitted into the roll sleeve 8 of the rear clamping platform 5. This allows the high-efficiency roll repair and grinding machine to process high-efficiency roll bodies 13 of different sizes and lengths. Internally equipped with a first telescopic cylinder 6, the front end of the first telescopic cylinder 6 is fixedly mounted with an abutment rod 7, and the other end of the abutment rod 7 is fixedly mounted with a roll sleeve 8. The roll sleeve 8 facilitates the synchronous rotation of the high-efficiency roll body 13 inside the roll sleeve 8 when the high-efficiency roll body 13 is rotated by the front jaw plate 10.

[0037] like Figure 1 , Figure 3 and Figure 4As shown, a drive motor 9 is externally mounted on the grinding machine 2. The output end of the drive motor 9 is rotatably connected to a front jaw disk 10. An abutment screw 11 passes through the outside of the front jaw disk 10. A clamping jaw 12 is threadedly connected to the bottom end of the abutment screw 11. A high-efficiency roller body 13 is installed inside the front jaw disk 10. The high-efficiency roller body 13 is firmly clamped by the front jaw disk 10, ensuring the stability and positional accuracy of the roller body during the grinding process. This helps to reduce grinding errors caused by the shaking or movement of the high-efficiency roller body 13, and improves the precision and quality of grinding. The high-efficiency roller body 13 is threadedly connected to the front jaw disk 10. The clamping jaws 12 are arranged in a ring array on the front jaw disk 10. The overall structure of the front jaw disk 10 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to perform timely maintenance without delaying the normal use of the device.

[0038] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the infrared scanner 19 is slidably connected to the upper scanning stage 15, and the sliding groove 16 works in conjunction with the sliding block 17. Under the push of the second telescopic cylinder 20, the infrared scanner 19 also synchronously follows the grinding head 32 to scan the grinding trajectory outside the high-efficiency roll body 13, and also transmits the data to the drive display controller 14 through the wire connection. The grinding column 25 is rotatably connected to the arm seat 23, and the robotic arm 27 is movably connected to the grinding column 25. The rotation of the grinding column 25 and the arm seat 23 can synchronously drive the grinding head 32 to adjust its angle, thereby meeting the grinding work in different positions. The grinding head 32 is rotatably connected to the grinding seat 28, and the grinding seat 28 is fixedly connected to the robotic arm 27, allowing the pressure sensor 33 and the robotic arm 27 to work together. The robotic arm 27 adjusts the angle of the grinding head 32, enabling the grinding head 32 to achieve adaptive capability for the high-efficiency roll body 13.

[0039] The working principle of this practical machine is as follows: First, connect the external power supply and take out the high-efficiency roll body 13 to be ground. According to the size and length of the high-efficiency roll body 13, first place one end of the high-efficiency roll body 13 into the front jaw plate 10 of the grinding machine 2. Then, twist the contact screw 11 to make the clamping jaws 12 clamp the high-efficiency roll body 13 in the middle from different directions. Next, turn on the switch of the first electric slide rail 3, adjust the position of the rear clamping table 5, and then turn on the switch of the first telescopic cylinder 6 so that the other end of the high-efficiency roll body 13 is fitted into the roll sleeve 8 of the rear clamping table 5. In this way, the high-efficiency roll repair and grinding machine can handle high-efficiency roll bodies 13 of different sizes and lengths. By adjusting the position of the rear clamping table 5, it can flexibly adapt to various sizes. The high-efficiency roll body 13 is securely clamped and fitted, ensuring its stability and positional accuracy during grinding. After preparation, the repair work can begin. First, the switch of the second electric slide rail 21 is turned on, allowing the second electric slide rail 21 and the second electric sliding sleeve 22 to move the entire arm seat 23. Then, the switch of the servo motor 24 is turned on, adjusting the position of the grinding column 25. Simultaneously, the hydraulic cylinder 26 is opened, adjusting the height of the robotic arm 27. The pressure sensor 33 inside the grinding disc 31 transmits the pressure between the grinding head 32 and the external contact point of the high-efficiency roll body 13 in real time via wires to the drive display control. The controller 14, then driven by the second telescopic cylinder 20, simultaneously guides the grinding head 32 to scan the grinding trajectory outside the high-efficiency roll body 13, and transmits the data to the drive display controller 14 via wires. This eliminates the need for manual control of the grinding path by the external operator. The operator adjusts the height and position of the robotic arm 27 based on the status reflected by the infrared scanner 19 and pressure sensor 33, and adjusts the angle of the grinding head 32, enabling the grinding head 32 to adapt to the high-efficiency roll body 13. This design also provides the high-efficiency roll repair and grinding machine with real-time scanning and feedback functions, with the pressure sensor 33 monitoring the grinding head 32 in real time. 2. Ensure the contact pressure with the roll surface is uniform and moderate, avoiding excessive pressure that could damage the roll surface or insufficient pressure that could lead to poor repair results, thus improving repair accuracy. Subsequently, the infrared scanner 19 scans the roll surface in real time to accurately identify the wear area and grinding path, avoiding missed grinding or over-grinding, and ensuring consistent repair quality. This allows the high-efficiency roll repair work to be completed normally. Finally, after completing all the installation and use of the high-efficiency roll repair and grinding machine according to the above operations, turn off the switches of the first electric slide rail 3 and the second electric slide rail 21, turn off the switch of the servo motor 24, and turn off the switch of the hydraulic cylinder 26. If not used for a long time, simply disconnect the external power supply. This completes the use of the high-efficiency roll repair and grinding machine.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
