Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical production technology, and in particular to a device for detecting the alignment of rolling mill rolls. Background Technology
[0002] The finishing mill is the core equipment in the metal rolling process, which mainly uses cold rolling technology to tightly process the base material.
[0003] Taking a bar mill for finishing rolling as an example, after the rolls are installed, the positions of the two rolls usually need to be checked. If they are not within the standard range, the roll positions need to be adjusted. In related technologies, a measuring tape or ruler is used to measure the midpoint of the two rolls and then compare it with the distance to the standard rolling center line. However, due to uneven ground, difficulty in determining the midpoint of the rolls, and deformation of measuring tools, inaccurate measurements can occur, leading to deviations in the rolling center line and affecting normal production.
[0004] Therefore, there is an urgent need to design a new roll alignment detection device for finishing mills to improve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a roll alignment detection device for a finishing mill, so as to solve the technical problems of inaccurate measurement, offset of the rolling center line, and impact on normal production caused by factors such as uneven ground, difficulty in determining the center position of the roll, and deformation of measuring tools.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] The finishing mill roll alignment detection device provided by this utility model includes:
[0008] A workbench, the upper surface of which is horizontal, is on which the finishing mill to be inspected rests;
[0009] A support frame is located on one side of the workbench, and a laser level is mounted on the side of the support frame facing the workbench.
[0010] An adjustment component is provided on the support frame. The adjustment component can be adjusted vertically and is fixed to the support frame. The laser level is connected to the adjustment component. The laser line and its extension line of the laser level are located between the two rollers.
[0011] The finishing mill is hoisted onto the workbench using a crane. The upper surface of the workbench maintains a high degree of flatness to facilitate determining the center position of the two rolls, reducing deviations during subsequent measurements. A laser level is installed on the support frame. The adjustment mechanism is adjusted to bring the laser level to a standard height where it is level with the center line of the gap between the two rolls. The adjustment mechanism can be used to accommodate rolls of different diameters and finishing mill sizes, offering good versatility. The laser level is turned on, and the laser beam is emitted and illuminates the space between the two rolls. The operator observes whether the laser beam is centered between the two rolls. If not, the test is unsuccessful, and the roll positions need to be adjusted. If it is centered, the test is successful, and no adjustment is needed. Laser technology possesses excellent characteristics such as high parallelism, rapid and accurate positioning, and no impact on the object being tested, enabling precise measurements when detecting the center position of the rolls.
[0012] As a preferred embodiment of the roll alignment detection device for a finishing mill, the support frame includes:
[0013] The base, the upper surface of which is flush with the upper surface of the worktable;
[0014] A support rod, one end of which is vertically fixed to the upper surface of the base.
[0015] The upper surface of the base also maintains a high degree of flatness and levelness, further reducing measurement deviation, while ensuring that the length of the support rod extends vertically.
[0016] As a preferred embodiment of the roll alignment detection device for a finishing mill, the two corresponding surfaces of the support rod are provided with a waist-shaped groove, the length of which extends vertically, and a first connecting piece connected to the laser level is inserted inside the waist-shaped groove.
[0017] After the first connector passes through the waist-shaped groove, its height position within the groove can be adjusted before it is connected and fixed to the laser level, allowing for a large adjustment range.
[0018] As a preferred embodiment of the roll alignment detection device for a finishing mill, the laser level has a first threaded hole, and the first connecting member includes:
[0019] The first bolt has its shank extending into the waist-shaped groove, and one end of the first bolt is threaded into the first threaded hole, so that the laser level and the head of the first bolt are pressed against the two corresponding surfaces of the support rod.
[0020] The shank of the first bolt passes through the waist-shaped groove. After adjusting the first bolt to the corresponding height position, the shank of the first bolt is threaded into the first threaded hole, so that the head of the first bolt and the laser level and the two corresponding surfaces of the support rod are kept in tight contact. The structure is simple and easy to install and disassemble.
[0021] As a preferred embodiment of the roll alignment detection device for a finishing mill, a scale is provided on the support rod, and the scale extends along the length direction of the waist-shaped groove.
[0022] Using a ruler allows for a more intuitive and rapid determination of the position of the first connector.
[0023] As a preferred embodiment of the roll alignment detection device for a finishing mill, the two corresponding surfaces of the support rod are provided with through holes, and multiple through holes are provided at equal intervals along the length of the support rod. A second connecting piece connected to the laser level is inserted into the through holes.
[0024] Simply pass the second connector through the through hole at the corresponding height position, and then connect the second connector to the laser level. This process is easy to manufacture.
[0025] As a preferred embodiment of the roll alignment detection device for a finishing mill, the laser level has a second threaded hole, and the second connecting member includes:
[0026] The second bolt has its shank extending into the through hole, and one end of the second bolt is threaded into the second threaded hole, so that the laser level and the head of the second bolt are pressed against the two corresponding surfaces of the support rod.
[0027] The shank of the second bolt passes through the through hole at the corresponding height position and is threaded into the second threaded hole, so that the head of the second bolt and the laser level and the two corresponding surfaces of the support rod are kept in tight contact. The structure is simple and easy to install and disassemble.
[0028] As a preferred embodiment of the roll alignment detection device for a finishing mill, a through groove is formed on two corresponding surfaces of the support rod, and toothed grooves are formed on the two corresponding inner sidewalls of the through groove. One end of the laser level is slidably inserted into the through groove, and a third connecting piece is slidably embedded in the toothed groove at the end of the laser level.
[0029] The gap between adjacent concave teeth in the tooth groove is the minimum distance for each adjustment, resulting in high adjustment accuracy and small error, making it suitable for high-precision fine-tuning.
[0030] As a preferred embodiment of the roll alignment detection device for a finishing mill, one end of the laser level is provided with a groove, and the third connecting member includes:
[0031] The head of the T-shaped rod is slidably embedded in the groove, and the rod part of the T-shaped rod extends out of the groove.
[0032] A limiting plate is connected to the extended end of the T-shaped rod. The limiting plate has toothed blocks that match the toothed groove on its opposite sides. The limiting plate is movably inserted into the through groove so that the toothed blocks mesh with the toothed groove.
[0033] The head of the T-shaped rod connects the laser level and the T-shaped rod into a whole. When the rod of the T-shaped rod is adjusted to extend into or out of the groove, the T-shaped rod will not come out of the laser level, which makes the whole between the two good. It ensures that the toothed block of the limiting plate is inserted into the toothed groove at the corresponding position. After the two are engaged, they can stably limit the laser level to the standard height. The structure is simple and the adjustment is convenient.
[0034] As a preferred embodiment of the roll alignment detection device for a finishing mill, the limiting plate is provided with a pull ring.

A laser level is installed on the support frame, and the adjustment component is adjusted to a standard height where the laser level is level with the center line of the gap between the two rolls. The height adjustment component can be used to accommodate rolls of different diameters and finishing mills of different sizes, offering good versatility. The laser level is turned on, and the laser beam is emitted and illuminates the space between the two rolls. The operator observes whether the laser is centered between the two rolls. If not, the test is unqualified, and the roll positions need to be adjusted; if so, the test is qualified, and no adjustment is required. The laser has excellent characteristics such as high parallelism, rapid and accurate positioning, and no impact on the object being tested, enabling precise measurement when detecting the center position of the rolls.

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0052] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0053] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0055] Example 1:
[0056] After the rolls of a finishing mill for processing bars are installed, the positions of the two rolls usually need to be checked. If they are not within the standard range, the roll positions need to be adjusted. In related technologies, a tape measure or ruler is used to measure the midpoint of the two rolls and then compare it with the distance to the standard rolling center line. However, due to uneven ground, difficulty in determining the midpoint of the rolls, and deformation of measuring tools, inaccurate measurements can occur, leading to deviations in the rolling center line and affecting normal production.
[0057] To solve the above problems, combined with Figures 1-3 As shown, the finishing mill roll alignment detection device provided in this embodiment includes a worktable 1 and a support frame 2.
[0058] Among them, such as Figure 1 As shown, the upper surface of the workbench 1 is horizontal, and the finishing mill to be inspected rests on the upper surface of the workbench 1. Before inspection, the finishing mill is hoisted onto the workbench 1 using a crane. The upper surface of the workbench 1 maintains a high degree of flatness, which improves the unevenness of the ground, makes it easier to determine the middle position of the two rolls, and can reduce the deviation during subsequent measurements.
[0059] The support frame 2 is located on one side of the workbench 1, and a laser level 3 is mounted on the side of the support frame 2 facing the workbench 1. Since the specific structure of the laser level 3 is existing technology, it will not be described in detail here.
[0060] To accommodate rolls of different diameters and finishing mills of different sizes, the finishing mill roll alignment detection device also includes an adjustment component 4. The adjustment component 4 is mounted on the support frame 2 and can be adjusted vertically and fixed to the support frame 2. A laser level 3 is connected to the adjustment component, and the laser line and its extension line of the laser level 3 are located between the two rolls. By adjusting the component 4, the height of the laser level 3 is adjusted to a standard height that is level with the center line of the gap between the two rolls, thereby improving adaptability.
[0061] During testing, the laser level 3 is activated, and the laser line is emitted and illuminates the area between the two rolls. The operator observes whether the laser is centered between the two rolls. If it is not, the test fails and the roll positions need to be adjusted. If it is, the test passes and no adjustment is required. The laser has excellent characteristics such as high parallelism, rapid and accurate positioning, and no impact on the object being tested, enabling precise measurement when testing at the center of the rolls.
[0062] Specifically, such as Figure 1 As shown, the support frame 2 includes a base 21 and a support rod. The upper surface of the base 21 is flush with the upper surface of the workbench 1. The upper surface of the base 21 also maintains a high degree of flatness and levelness, which further reduces measurement deviation. One end of the support rod 22 is vertically fixed to the upper surface of the base 21, while ensuring that the length of the support rod 22 extends in the vertical direction.
[0063] Optionally, such as Figure 2 and Figure 3 As shown, a waist-shaped groove 41 is formed through two corresponding surfaces of the support frame 2. The length of the waist-shaped groove 41 extends vertically, and a first connector connected to the laser level 3 passes through the waist-shaped groove 41. After the first connector passes through the waist-shaped groove 41, its height position within the waist-shaped groove 41 can be adjusted before it is connected and fixed to the laser level 3, providing a large adjustable range.
[0064] In this embodiment, the first connecting component is a first bolt 43. A first threaded hole 42 is provided on the laser level 3. The shank of the first bolt 43 extends into the slot 41, and one end of the first bolt 43 is threaded into the first threaded hole 42, so that the laser level 3 and the head of the first bolt 43 abut against the two corresponding surfaces of the support rod 22. The shank of the first bolt 43 passes through the slot 41. After adjusting the first bolt 43 to the corresponding height position, the shank of the first bolt 43 is threaded into the first threaded hole 42, ensuring that the head of the first bolt 43 and the two corresponding surfaces of the laser level 3 and the support rod remain tightly abutted. The structure is simple and easy to install and disassemble.
[0065] In order to achieve intuitive and precise adjustment of the position of the first bolt 43, such as Figure 3As shown, a scale 44 is provided on the support rod 22, extending along the length of the waist-shaped groove 41. With the reference of the scale 44, the position of the first bolt 43 can be determined intuitively and quickly. Preferably, the smallest unit of measurement of the scale 44 is millimeters.
[0066] Example 2:
[0067] This embodiment differs from Embodiment 1 in its adjustment component 4 configuration. In this embodiment, the two corresponding surfaces of the support rod have through holes, and multiple through holes are evenly spaced along the length of the support rod 22. This embodiment has five through holes, and adjacent through holes can be spaced apart or overlapped in the vertical direction. In other embodiments, the number of through holes can be three, four, or even more, and the shape of the through holes can be circular, elliptical, or rectangular, etc. This embodiment does not impose specific limitations on these aspects. A second connector, connected to the laser level 3, passes through the through hole. The second connector is simply passed through the through hole at the corresponding height position and then connected to the laser level 3, making it easy to manufacture.
[0068] Specifically, the second connecting component is a second bolt. The laser level 3 has a second threaded hole. The shank of the second bolt extends into the through hole, and one end of the second bolt is threaded into the second threaded hole, so that the laser level 3 and the head of the second bolt are pressed against the two corresponding surfaces of the support rod 22. The shank of the second bolt passes through the through hole at the corresponding height position and is threaded into the second threaded hole, ensuring that the head of the second bolt and the two corresponding surfaces of the laser level 3 and the support rod are pressed together. The structure is simple and easy to install and disassemble.
[0069] Example 3:
[0070] Combination Figures 4-6 As shown, the adjustment component 4 provided in this embodiment differs from that in Embodiment 1. In this embodiment, a through groove 401 is formed on two corresponding surfaces, and toothed grooves 4011 are formed on the two opposite inner sidewalls of the through groove 401. One end of the laser level 3 is slidably inserted into the through groove 401, and a third connecting member is slidably embedded in the toothed groove 4011 at the end of the laser level 3. The gap between adjacent concave teeth of the toothed groove 4011 is the minimum distance for each adjustment. Preferably, the gap between adjacent concave teeth is 1mm, resulting in high adjustment accuracy and small error, suitable for high-precision fine-tuning.
[0071] Specifically, such as Figure 4 and Figure 5As shown, the third connecting member includes a T-shaped rod 403 and a limiting plate 404. One end of the laser level 3 has a groove 402. The head of the T-shaped rod 403 is slidably embedded in the groove 402, and the rod portion of the T-shaped rod 403 extends out of the groove 402. The limiting plate 404 is connected to the extended end of the rod portion of the T-shaped rod 403. The limiting plate 404 has toothed blocks 4041 that match the toothed groove 4011 on opposite sides. The limiting plate 404 is movably inserted into the through groove 401 so that the toothed blocks 4041 mesh with the toothed groove 4011.
[0072] See Figure 5 The head of the T-shaped rod 403 connects the laser level 3 and the T-shaped rod 403 into a whole. When the rod of the T-shaped rod 403 is adjusted to extend into or out of the groove 402, the T-shaped rod 403 will not come out of the laser level 3, which makes the whole between the two good. It ensures that the toothed block 4041 of the limiting plate 404 is inserted into the toothed groove 4011 at the corresponding position. After the two are engaged, the laser level 3 can be stably limited to the standard height. The structure is simple and the adjustment is convenient.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
