[0002] A rolling mill work roll structure, as described in Chinese document CN205056633U, includes a shaft with integrally formed mounting shafts of equal diameter at both ends. The diameter of the mounting shafts is smaller than that of the shaft. An integrally formed fastening shaft of equal diameter is located at the outer end of the mounting shaft. The outer wall of the fastening shaft has external threads. Positioning posts and positioning plates are respectively provided on the left and right end faces of the shaft around the outer circumference of the mounting shaft. This invention, by setting positioning posts and positioning plates at an annular interval at both ends of the shaft, prevents minor axial and radial displacements during vibration or stress during operation, resulting in good stability and a long service life.

[0003] The aforementioned rolling mill work roll structure has a fixed mounting shaft on the roll body. This not only makes it inconvenient to replace the roll body during use, but also wastes a lot of material. At the same time, it is difficult to automatically measure the lateral flatness and eccentricity of the work roll body. If this is not done in time, it may cause unevenness in a batch of products. Utility Model Content

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a wear-resistant multi-roll mill work roll, including mounting blocks 1, tie rod type displacement sensors 12, and abutting structure 9. The number of mounting blocks 1 is two sets, which are distributed left and right. A sliding sleeve 2 is fixedly installed on the outer wall of the mounting blocks 1. A work roll body 3 and a mounting strip 7 are arranged between the two sets of mounting blocks 1. A connecting component is provided on the mounting blocks 1 and the work roll body 3. The tie rod type displacement sensors 12 are fixedly installed on the outer wall of the mounting strip 7. There are three sets of tie rod type displacement sensors 12, which are distributed horizontally at equal intervals. The free end of the tie rod type displacement sensor 12 passes through the mounting strip 7 and is fixedly connected to a moving plate 10. A round protrusion 11 is fixedly installed on the outer wall of the moving plate 10. The round protrusion 11 contacts the outer wall of the work roll body 3. The abutting structure 9 is arranged on the mounting strip 7 and the moving plate 10. The abutting structure 9 is used to drive the movement of the moving plate 10.

[0017] The connecting assembly includes a connecting column 4, a connecting plate 5, and a bolt 6. The connecting column 4 is movably mounted on the mounting block 1 and the sliding sleeve 2. The connecting column 4 is fixedly connected to the connecting plate 5. The connecting plate 5 has a through hole. The working roller body 3 has a receiving groove and a threaded opening communicating with it. The bolt 6 passes through the through hole and is threaded into the threaded opening. A diagonal brace 14 is fixedly mounted on the outer wall of the connecting column 4. The diagonal brace 14 is fixedly connected to the connecting plate 5. Connecting blocks 13 are fixedly mounted on both sides of the mounting strip 7. Screws are provided on the connecting blocks 13. One end of the screw passes through the connecting block 13 and is threadedly connected to the mounting block 1. The working roller body 3 is made of forged steel.

[0018] The clamping structure 9 includes a housing 91, a slider 92, a guide rod 93, and a tension spring 94. The housings 91 are arranged in three sets, equidistant laterally, with each set consisting of two housings arranged front-to-back. The housings 91 are fixedly mounted on the outer wall of the mounting strip 7. The slider 92 is slidably mounted inside the housing 91. The tension spring 94 is fixedly mounted between the slider 92 and the mounting strip 7. The guide rod 93 is slidably mounted on the mounting strip 7, with both ends fixedly connected to the slider 92 and the moving plate 10, respectively. A protective cover 8 is fixedly mounted on the outer wall of the mounting strip 7, and both housings 91 are fixedly mounted inside the protective cover 8. A pull-rod type displacement sensor 12 is located between the two sets of housings 91. When the working roller body 3 needs to be replaced, the bolt 6 is removed using a wrench, and then the connecting plate 5 is pulled to separate it from the working roller body 3, allowing for disassembly of the working roller body 3. It can then be reassembled. When the working roller body 3 rotates, the tension spring 94 automatically tightens the slider 92 and the guide rod 93, thereby driving the round protrusion 11 to firmly clamp the roller body. On the work roller body 3, if the surface is uneven when the work roller body 3 rotates, the round convex head 11 will automatically move. The pull rod displacement sensor 12 will automatically detect and measure the eccentricity. By comparing the measurements of the three sets of pull rod displacement sensors 12, the lateral flatness of the work roller body 3 can be known. On the one hand, it makes the installation and disassembly of the work roller body 3 very convenient, which facilitates the subsequent maintenance or replacement of the work roller body 3. At the same time, the combination of the connecting plate 5 and the work roller body 3 reduces the material cost of replacing the work roller body 3 itself. On the other hand, it can automatically measure the wear and flatness of the work roller body 3 during use, preventing the large wear on both sides or the middle of the work roller body 3 from going undetected and causing unevenness in the processed products. At the same time, it can also measure the eccentricity of the work roller body 3 at multiple points to ensure pressure balance, thereby ensuring the processing quality, reducing the probability of rework and the resulting cost accumulation, and improving the practicality of the work roller.

[0019] Working principle: When the working roller body 3 needs to be replaced, use a wrench to remove the bolt 6, and then pull the connecting plate 5 to separate it from the working roller body 3. The working roller body 3 can then be disassembled and reassembled. When the working roller body 3 rotates, the tension spring 94 automatically tightens the movement of the slider 92 and the guide rod 93, which in turn drives the round protrusion 11 to firmly press against the working roller body 3. If the surface of the working roller body 3 is uneven when it rotates, the round protrusion 11 will automatically move, and the pull rod displacement sensor 12 will automatically detect and measure the eccentricity. By comparing the measurements of the three sets of pull rod displacement sensors 12, the lateral flatness of the working roller body 3 can be determined.

[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
