Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment technology, specifically relating to a gauge for adjusting the position of the side rollers of the sector segment. Background Technology

[0002] In continuous casting equipment, the sector section is a key component that supports and guides the cast billet, and the flatness of the outer surface of its side rolls directly affects the quality of the cast billet and the stability of the equipment operation. Therefore, during maintenance of the sector section, the outer surfaces of all side rolls must be finely adjusted to ensure that they are on a flat reference surface;

[0003] In existing technology, the conventional method for adjusting the flatness of side rollers is to use a straight gauge or straightedge. The operator places the two reference surfaces of the gauge against the side surfaces of the first and last rollers of the sector section, respectively, using these as reference planes. Then, the gap between the middle part of the gauge and the surfaces of the intermediate side rollers (such as side rollers number two, three, and four) is observed. The gap size is measured using a feeler gauge, and the thickness of the shims on the intermediate side rollers is adjusted accordingly to make the surfaces of all side rollers tend to be flat.

[0004] In traditional methods, when the surface of the middle side roller is recessed into the fan-shaped section relative to the surfaces of the first and last rollers, the straight gauge can effectively detect the gap. However, when the surface of the middle side roller protrudes outward, the middle part of the gauge is pushed up by the protruding roller, causing the reference surfaces at both ends of the gauge to be unable to simultaneously and stably adhere to the first and last rollers, thus rendering the established reference plane ineffective. In this situation, operators cannot directly and accurately measure the gap and can only rely on experience to repeatedly estimate and adjust it. The whole process is cumbersome, inefficient, and the adjustment accuracy is difficult to guarantee, which seriously affects the maintenance quality and maintenance cycle. Therefore, we propose a gauge for adjusting the position of the side rollers in the fan-shaped section. Utility Model Content

[0005] To address the problem in the traditional method described in the background that, during use, when the surface of the middle side roller protrudes outward, the middle part of the gauge is pushed up by the protruding roller, causing the two reference surfaces of the gauge to fail to simultaneously and stably adhere to the first and last rollers, thus rendering the established reference plane invalid. In this situation, operators cannot directly and accurately measure the gap and can only rely on experience to repeatedly estimate and adjust, making the entire process cumbersome, inefficient, and difficult to guarantee adjustment accuracy, seriously affecting maintenance quality and maintenance cycle. This utility model provides a gauge for adjusting the position of the side rollers in the fan-shaped section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gauge for adjusting the position of the side rollers of a fan-shaped section, comprising a gauge body and a measuring section. The measuring section is fixedly connected to the middle of the gauge body. A first side roller and a tail side roller are respectively arranged on both sides of one end of the gauge body. Multiple inner side rollers are arranged on the inner side of the first side roller and the tail side roller. An insertion groove is opened in the middle of one end of the first side roller and the tail side roller. An insertion post is fixedly connected to the gauge body at the position corresponding to the insertion groove. A threaded hole is opened on the side of the gauge body away from the measuring section from the insertion post. A positioning screw is installed in the threaded hole.

[0007] A preset groove is provided on one end face of the measuring section, and a miniature displacement sensor for measuring the distance between it and the end face of the inner roller is installed in the preset groove.

[0008] As a preferred embodiment of this utility model for adjusting the position of the side rollers of the fan-shaped section, the insert post is used to insert into the insert groove to achieve the pre-positioning of the sample body with the first side roller and the tail side roller.

[0009] As a preferred sample of this utility model for adjusting the position of the fan-shaped side rollers, the end of the positioning screw extends into the end faces of the first side roller and the tail side roller respectively when tightened.

[0010] As a preferred embodiment of this utility model for adjusting the position of the side rollers of the fan-shaped section, a level bubble for calibrating the horizontal state of the gauge is installed on one side of the outer wall of the measuring section.

[0011] As a preferred sample gauge for adjusting the position of the side rollers of the fan-shaped section according to this utility model, a display screen for displaying the measurement values ​​of the micro displacement sensor is installed on the other end face of the measuring section.

[0012] As a preferred sample gauge for adjusting the position of the side rollers in the fan-shaped section according to this utility model, the flatness error between the end faces of the first and last side rollers and the reference surface of the sample gauge body is less than or equal to . mm.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application establishes a rigid and stable reference mechanism through the pre-positioning of the insertion post and insertion slot, and the locking positioning of the positioning screw. This mechanism ensures that regardless of whether the intermediate side roller is concave or convex, the gauge can always stably use the end faces of the first and last rollers as the reference, completely solving the problem of inaccurate reference surfaces when the intermediate roller protrudes using traditional rulers. The integrated micro displacement sensor and display screen enable digital, non-contact measurement of the gap, providing intuitive and accurate readings. This avoids the human error and operational inconvenience of feeler gauge measurements, and prevents the problems of cumbersome and inefficient processes and difficulty in guaranteeing adjustment accuracy associated with traditional methods, which seriously affect maintenance quality and cycle time.

[0020] 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.

[0021] Example 1

[0022] like Figures 1-4 As shown;

[0023] A gauge for adjusting the position of the side rollers in a fan-shaped section includes a gauge body 1 and a measuring section 2. The measuring section 2 is fixedly connected to the middle of the gauge body 1. A first side roller 3 and a tail side roller 4 are respectively arranged on both sides of one end of the gauge body 1. Multiple inner side rollers 5 are arranged on the inner side of the first side roller 3 and the tail side roller 4. An insertion groove 6 is opened in the middle of one end of the first side roller 3 and the tail side roller 4. An insertion post 7 is fixedly connected to the gauge body 1 at the position corresponding to the insertion groove 6. A threaded hole 9 is opened on the side of the gauge body 1 away from the measuring section 2 on the side of the insertion post 7. A positioning screw 8 is installed in the threaded hole 9. A preset groove 10 is opened on one end face of the measuring section 2. A miniature displacement sensor 11 for measuring the distance between it and the end face of the inner side roller 5 is installed in the preset groove 10.

[0024] In this implementation scheme, a rigid and stable reference establishment mechanism is formed by the pre-positioning of the insertion post 7 and the insertion slot 6, and the locking positioning of the positioning screw 8. This mechanism ensures that the gauge can always stably use the end faces of the first and last rollers as the reference, regardless of whether the middle side roller is concave or convex. This completely solves the problem of reference surface inaccuracy when the middle roller is convex, which is a problem with traditional rulers. The integrated micro displacement sensor 11 and display screen 12 realize digital and non-contact measurement of the gap. The readings are intuitive and accurate, avoiding the human error and operational inconvenience of feeler gauge measurement.

[0025] In an optional embodiment, the plug 7 is used to insert into the plug slot 6 to achieve pre-positioning of the pattern body 1 with the first side roller 3 and the tail side roller 4.

[0026] In this implementation plan, the cooperation between the plug-in post 7 and the plug-in slot 6 provides operators with an intuitive and quick positioning guide. When placing the sample gauge, simply align the plug-in post 7 with the plug-in slot 6 and insert it to quickly complete the pre-positioning of the sample gauge body 1 with the first side roller 3 and the tail side roller 4.

[0027] In an optional embodiment, the end of the positioning screw 8 extends into the end faces of the first side roller 3 and the tail side roller 4, respectively, when tightened.

[0028] In this implementation scheme: by tightening the positioning screw 8 so that its end is screwed into the corresponding roller, all connection gaps can be eliminated, so that the gauge body 1 and the side roller are firmly combined into a whole, thereby establishing an extremely stable and reliable measurement reference plane.

[0029] In an optional embodiment, a level bubble 13 for calibrating the level of the gauge is installed on one side of the outer wall of the measuring section 2.

[0030] In this implementation plan, bubble level 13 provides an intuitive visual indication, ensuring that operators adjust the gauge to a horizontal position before measurement, thus eliminating systematic measurement errors caused by the inclination of the reference plane.

[0031] In an optional embodiment, a display screen 12 for displaying the measurement values ​​of the miniature displacement sensor 11 is mounted on the other end face of the measuring segment 2.

[0032] In this implementation scheme, the signal detected by the miniature displacement sensor 11 is directly converted into a digital display on the display screen 12, and the operator can directly read the precise gap value, completely avoiding the reading error and human judgment deviation caused by feel, viewing angle and wear of feeler gauge when using feeler gauges.

[0033] In an optional embodiment, the flatness error between the end faces of the first side roller 3 and the tail side roller 4 and the reference surface of the gauge body 1 is less than or equal to 0.05 mm.

[0034] In this implementation plan: This accuracy index is the cornerstone of ensuring the accuracy of the entire measurement system, and it controls the error that may be caused by the manufacturing of the gauge itself to be within a very small range.

[0035] Working principle:

[0036] Preparation and initial positioning: Clean the end faces of each side roller of the fan-shaped section, including the first side roller 3, the last side roller 4 and the inner side roller 5, and ensure that there are no foreign objects. Lift up the gauge body 1 and align the insertion post 7 on it with the insertion groove 6 on the end face of the first side roller 3 and the last side roller 4. Then gently push it in to achieve rapid pre-positioning of the gauge and ensure the initial alignment of the gauge with the end face of the side rollers.

[0037] Precise positioning and benchmark establishment: After the gauge is in place through the plug-in structure, the positioning screw 8 installed in the threaded hole 9 is tightened. The end of the positioning screw 8 moves forward and extends into the holes in the end faces of the first side roller 3 and the tail side roller 4 respectively. Through mechanical locking, the possible small gaps in the plug-in fit are eliminated, so that the gauge body 1 is firmly combined with the first side roller 3 and the tail side roller 4 into a whole. This ensures the absolute stability with the end faces of the first side roller 3 and the tail side roller 4 as the benchmark. Observe the horizontal bubble 13 installed on the outer wall of one side of the measuring section 2. Make sure that the bubble of the horizontal bubble 13 is in the center. This ensures that the established measuring benchmark plane is in a horizontal state and avoids measurement errors caused by the gauge itself tilting.

[0038] After the baseline is established, the probe of the miniature displacement sensor 11 on the measurement section 2 is aligned with the end face of the inner roller 5 that needs to be adjusted. The miniature displacement sensor 11 will measure the actual distance between the probe and the end face of the inner roller 5 with high precision and display it on the display screen 12 in real time. The gap value accurate to 0.01mm can be read directly from the display screen 12. The measurement process is fast and intuitive. The miniature displacement sensor 11 and the display screen 12 are both mature products in the existing technology. Their principles will not be elaborated here.

[0039] Data analysis and adjustment: The actual measured value read on the display screen 12 is compared with the preset standard gap value, such as 5mm. If the measured value is greater than the standard value, it means that the surface of the inner roller 5 is concave inward, and the shim thickness needs to be increased to adjust it outward. If the measured value is less than the standard value, it means that the surface of the inner roller 5 is protruding outward, and the shim thickness needs to be reduced to adjust it inward. The measurement-adjustment process is repeated until the measured values ​​of all inner rollers 5 are within the standard tolerance range, such as 5mm ± 0.2mm. At this point, the flatness of the outer surface of all side rollers is precisely adjusted to the correct position.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
