Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, and in particular to an auxiliary roller changing device for plate rolling machines. Background Technology

[0002] During the long-term use of plate rolling machines, roller replacement is a crucial step in ensuring normal equipment operation and plate rolling quality. However, traditional roller changing methods for plate rolling machines have several significant drawbacks, severely impacting changing efficiency, operational safety, and equipment accuracy. Firstly, roller changing efficiency is low. Traditional roller changing relies primarily on manual operation using simple tools. For heavier rollers, multiple workers are required, leading to high labor intensity. In production scenarios requiring frequent roller changes, this results in prolonged machine downtime, severely impacting production progress. Secondly, roller changing accuracy is difficult to guarantee. Manual operation makes it difficult to precisely control the disassembly and installation positions of the rollers, easily causing positioning deviations. This leads to unstable transmission in subsequent operations, resulting in dimensional inaccuracies and poor surface flatness in the rolled plates, increasing product defect rates and raising production costs.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: During the manual handling and disassembly of rollers, due to the large weight of the rollers and the limited operating space, it is very easy for safety accidents such as roller slippage and tool injuries to occur. This may not only cause equipment damage, but also pose a serious threat to the personal safety of operators, resulting in a high incidence of work-related accidents. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that during the manual handling and disassembly of rollers, due to the large weight of the rollers and the limited operating space, it is easy for the rollers to slip and cause tool injuries. To this end, we propose an auxiliary roller changing device for plate rolling machines.

[0005] To achieve the above objectives, this application adopts the following technical solution: an auxiliary roller changing device for a plate rolling machine, comprising a fixed plate, a groove formed on the surface of the fixed plate, an mounting plate slidably connected to the inner wall of the groove, a connecting plate fixedly connected to one side of the mounting plate, two first servo motors fixedly connected to the surface of the connecting plate, a lead screw fixedly connected to the output end of the first servo motors, a setting plate slidably connected to the arc surface of the lead screw, a disassembly hook fixedly connected to one side of the setting plate, a sliding hole formed on the surface of the connecting plate, and the setting plate slidably connected to the inner wall of the sliding hole.

[0006] Preferably, the surface of the disassembly hook is fixedly connected with several anti-slip features.

[0007] Preferably, the size of the setting plate is adapted to the size of the sliding hole in the connecting plate.

[0008] Preferably, a second servo motor is fixedly connected to the surface of the fixing plate, and a threaded rod is fixedly connected to the output end of the second servo motor. The mounting plate and the threaded rod are threadedly connected to each other on the arc surface.

[0009] Preferably, the surface of the fixing plate has two limiting grooves, and L-shaped plates are fixedly connected to both sides of the mounting plate, with the L-shaped plates slidably connected to the inner wall of the limiting grooves.

[0010] Preferably, a protective pad is fixedly connected to the bottom of the fixing plate.

[0011] Preferably, the two sides of the disassembly hook are arc-shaped.

[0012] The technical effects and advantages of this utility model are as follows: An automated roller changing system is formed by a fixed plate, a mounting plate, a connecting plate, a first servo motor, a lead screw, a setting plate, and a disassembly hook. The first servo motor drives the lead screw to rotate, which in turn drives the setting plate and the disassembly hook to slide along the sliding hole. Combined with the sliding of the mounting plate in the sliding groove of the fixed plate, the precise disassembly and installation of the roller shaft are achieved. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1-4As shown, this utility model provides a technical solution: an auxiliary roller changing device for a plate rolling machine, including a fixed plate 1, a groove 12 on the surface of the fixed plate 1, an mounting plate 2 slidably connected to the inner wall of the groove 12, a connecting plate 3 fixedly connected to one side of the mounting plate 2, two first servo motors 4 fixedly connected to the surface of the connecting plate 3, a lead screw 5 fixedly connected to the output end of the first servo motor 4, a setting plate 6 slidably connected to the arc surface of the lead screw 5, a disassembly hook 7 fixedly connected to one side of the setting plate 6, a sliding hole on the surface of the connecting plate 3, and the setting plate 6 slidably connected to the inner wall of the sliding hole. The fixed plate 1, mounting plate 2, connecting plate 3, first servo motors 4, lead screw 5, setting plate 6, and disassembly hook 7 constitute an automated roller changing device. Roller System: The first servo motor 4 drives the lead screw 5 to rotate, causing the setting plate 6 and the disassembly hook 7 to slide along the sliding hole. Combined with the sliding of the mounting plate 2 in the sliding groove 12 of the fixed plate 1, the roller shaft can be accurately disassembled and installed. Several anti-slip blocks 8 are fixedly connected to the surface of the disassembly hook 7. The anti-slip blocks 8 can increase the friction between the disassembly hook 7 and the roller shaft, which can effectively prevent slippage during the disassembly and handling of the roller shaft. The size of the setting plate 6 is adapted to the size of the sliding hole of the connecting plate 3. The precise matching of the size of the setting plate 6 and the sliding hole can limit the radial sway of the setting plate 6 during the sliding process, ensuring that the disassembly hook 7 moves stably only along the axial direction of the sliding hole, improving the positioning accuracy of the disassembly hook 7 on the roller shaft. The surface of the fixed plate 1 is fixedly connected to the second... The output end of the second servo motor 10 is fixedly connected to a threaded rod 11. The mounting plate 2 is threadedly connected to the arc surface of the threaded rod 11. The second servo motor 10 drives the threaded rod 11 to rotate, which can drive the mounting plate 2 to move precisely along the slide groove 12 of the fixed plate 1, realizing the automated position adjustment of the mounting plate 2 and connected components. Two limiting grooves 13 are opened on the surface of the fixed plate 1. L-shaped plates 14 are fixedly connected to both sides of the mounting plate 2. The L-shaped plates 14 are slidably connected to the inner wall of the limiting grooves 13. The L-shaped plates slide in the limiting grooves 13, which can play a dual guiding and limiting role for the movement of the mounting plate 2, limiting the lateral displacement and vertical sway of the mounting plate 2 during the movement, and ensuring that the mounting plate 2 drives the connecting plate 3. The components such as the disassembly hook 7 move stably along the set trajectory, improving the overall structural stability during the roller changing process. The bottom of the fixed plate 1 is fixedly connected with a protective pad 15, which can buffer the vibration and impact between the fixed plate 1 and the installation foundation, reducing the impact of the vibration generated by the equipment operation during the roller changing process on the installation stability of the fixed plate 1. The two sides of the disassembly hook 7 are arc-shaped. The arc-shaped surface design can avoid the disassembly hook 7 from scratching or bumping the roller shaft surface during contact with the roller shaft and disassembly process. It is especially suitable for roller shafts with high surface precision requirements. At the same time, the arc-shaped surface can reduce the stress concentration when the disassembly hook 7 contacts the roller shaft, protect the structure of the disassembly hook 7 itself, extend its service life, and make the disassembly process smoother and reduce jamming.

[0017] Working Principle: When the roller shaft of the plate rolling machine needs to be replaced, the device is supported by the fixed plate 1. The mounting plate 2 can slide along the slide groove 12 on the surface of the fixed plate 1, providing lateral movement adjustment space for the roller replacement operation. The connecting plate 3 is fixed to one side of the mounting plate 2, and the two first servo motors 4 on its surface are started, driving the lead screw 5 to rotate. Since the setting plate 6 is slidably connected to the arc surface of the lead screw 5 and slidably engaged with the inner wall of the slide hole of the connecting plate 3, the rotational motion of the lead screw 5 is converted into the axial sliding of the setting plate 6 along the slide hole, thereby driving the disassembly hook 7 on one side of the setting plate 6 to move synchronously, realizing the precise gripping and disassembly of the roller shaft. The anti-slip block 8 on the surface of the disassembly hook 7 increases the friction between it and the roller shaft, effectively preventing slippage during disassembly and transportation, and ensuring stable force on the roller shaft. At the same time, the arc surface design on both sides of the disassembly hook 7 avoids scratches or bumps when in contact with the roller shaft, reduces contact stress concentration, protects the surface precision of the roller shaft and the structure of the disassembly hook 7 itself, and makes the disassembly... The unloading process is smoother. The size of the setting plate 6 is precisely matched with that of the sliding hole, which limits the radial sway of the setting plate 6 and ensures that the disassembly hook 7 moves stably only along the axial direction of the sliding hole, thus improving the positioning accuracy of the roller shaft. If the position of the mounting plate 2 and the connected components needs to be adjusted, the second servo motor 10 on the surface of the fixing plate 1 drives the threaded rod 11 to rotate. Since the mounting plate 2 is threadedly connected to the threaded rod 11, the rotation of the threaded rod 11 drives the mounting plate 2 to move precisely along the sliding groove 12, realizing automated position adjustment. During this process, the L-shaped plates on both sides of the mounting plate 2 slide in the limiting groove 13 of the fixing plate 1, which plays a dual guiding and limiting role, limiting the lateral offset and vertical sway of the mounting plate 2, ensuring that the overall structure moves stably along the set trajectory, and improving the stability of the roller changing process. In addition, the protective pad 15 at the bottom of the fixing plate 1 buffers the vibration and impact between it and the mounting foundation, reducing the impact of equipment operation vibration on the installation stability of the fixing plate 1, and ensuring the safety and reliability of the entire roller changing operation.

[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
