[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please refer to Figures 1-4. This utility model provides a technical solution: a cold rolling mill roll grinding wheel, comprising:

[0027] The rotating shaft body 1 is provided with a cavity 2;

[0028] Sleeve 3 is movably fitted onto the outer wall of the rotating shaft body 1;

[0029] The grinding wheel body 4 is fixedly sleeved on the outer wall of the sleeve 3;

[0030] Limiting plate 5 is fixedly sleeved on the outer wall of rotating shaft body 1;

[0031] The positioning mechanism 6 is provided in multiple sets. Each set of positioning mechanism 6 is equidistantly arranged on the limiting plate 5 along the circumferential direction. It is used to limit the position of the grinding wheel body 4 on the rotating shaft body 1.

[0032] The fixing mechanism 7 is located inside the cavity 2 and is used to install and fix the grinding wheel body 4 on the rotating shaft body 1.

[0033] In this implementation scheme: the cavity 2 is used to accommodate the fixing mechanism 7, and the sleeve 3 serves as the mounting carrier for the grinding wheel body 4, facilitating the installation and positioning of the grinding wheel body 4. The limiting plate 5 limits the placement position of the sleeve 3 and provides an installation base for the positioning mechanism 6, ensuring the stability of the positioning mechanism 6. The grinding wheel body 4 is the working part that directly grinds the cold rolling roll. The positioning mechanism 6 can accurately limit the position of the grinding wheel body 4 on the rotating shaft body 1, ensuring the positional accuracy of the grinding wheel installation. The fixing mechanism 7 firmly fixes the grinding wheel body 4 to the rotating shaft body 1, increasing the stability of the grinding wheel installation and avoiding cumbersome installation.

[0034] Specifically, each positioning mechanism 6 includes a positioning rod 601 and a positioning hole 602. The positioning rod 601 is fixedly set on one side of the outer wall of the limiting plate 5, and the positioning hole 602 is opened on one side of the outer wall of the sleeve 3. The positioning rod 601 is slidably embedded in the inner wall of the positioning hole 602.

[0035] In this embodiment, the position of the grinding wheel body 4 on the rotating shaft body 1 can be accurately defined by the positioning rod 601 and the positioning hole 602.

[0036] Specifically, the fixing mechanism 7 includes a driving component, a rotating frame 701, four sets of moving components, four fixing rods 702, and four fixing holes 703. The driving component is located inside the cavity 2, the rotating frame 701 is located on the driving component, each set of moving components is equidistantly located on the rotating frame 701 along the circumferential direction, each fixing rod 702 is located on the moving component, and each fixing hole 703 is opened on one side of the outer wall of the positioning rod 601. Each fixing rod 702 is slidably embedded in the inner wall of the fixing hole 703.

[0037] In this embodiment: the driving component drives the rotating frame 701 to rotate. The rotation of the rotating frame 701, in conjunction with the moving component, causes each fixed rod 702 to enter, thereby firmly fixing the grinding wheel body 4 onto the rotating shaft body 1.

[0038] Specifically, the driving component includes a partition 704, a rotating shaft 705, a first bevel gear 706, and a second bevel gear 707. The partition 704 is fixedly disposed on the inner wall of the cavity 2. The rotating frame 701 is rotatably embedded in one side of the outer wall of the partition 704. The rotating shaft 705 is rotatably embedded in one side of the inner wall of the cavity 2. The first bevel gear 706 is fixedly sleeved on the outer wall of the rotating shaft 705. The second bevel gear 707 is fixedly sleeved on the outer wall of the rotating frame 701, and the second bevel gear 707 meshes with the first bevel gear 706.

[0039] In this embodiment, the rotating shaft 705 is provided with an anti-reverse device to limit the rotation of the rotating shaft 705. By rotating the rotating shaft 705, the first bevel gear 706 is driven to rotate, thereby driving the second bevel gear 707 to drive the rotating frame 701 to rotate on the partition plate 704.

[0040] Specifically, each set of moving parts includes a connecting rod 708 and a guide groove 709. One end of the connecting rod 708 is movably sleeved on the outer wall of the rotating frame 701, and the other end of the connecting rod 708 is movably sleeved on the outer wall of the fixed rod 702. The guide groove 709 is opened on one side of the inner wall of the cavity 2.

[0041] In this embodiment: as the rotating frame 701 rotates, the connecting rod 708 can drive the fixed rod 702 to move along the guide groove 709.

[0042] Specifically, each fixing rod 702 is slidably embedded in the inner wall of the guide groove 709, and each fixing rod 702 is slidably penetrated through the outer wall of the rotating shaft body 1.

[0043] In this embodiment, the guide groove 709 guides the movement of the fixing rod 702 so that the fixing rod 702 can pass through the positioning hole 602 and enter the fixing hole 703.

[0044] In use, first, put the sleeve 3 on the rotating shaft body 1 and align the positioning rod 601 with the positioning hole 602. Push the sleeve 3 to move along the rotating shaft body 1. When the positioning rod 601 slides into the positioning hole 602, the grinding wheel body 4 is initially positioned. Then, rotate the rotating shaft 705. Through the meshing transmission of the first bevel gear 706 and the second bevel gear 707, the rotating frame 701 is driven to rotate. The rotating frame 701 drives the fixing rod 702 to move along the guide groove 709 through the connecting rod 708, so that the fixing rod 702 slides into the fixing hole 703, and the grinding wheel body 4 is firmly fixed on the rotating shaft body 1. When it is necessary to replace the grinding wheel, rotate the rotating shaft 705 in the opposite direction to make the fixing rod 702 exit the fixing hole 703. Then, the sleeve 3 can be removed from the rotating shaft body 1.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
