DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1 - 3, a ceramic grinding wheel for polishing the outer wall of a pipeline, comprising:

[0021] A fixed grinding wheel 1 is provided with an installation hole 2. The installation hole 2 penetrates through the fixed grinding wheel 1. A fixing ring 3 is fixedly connected to one side side wall of the fixed grinding wheel 1. The fixed grinding wheel 1 is installed on the grinding machine through the fixing ring 3. The rotating rod of the grinding machine passes through the fixing ring 3 and extends to the installation hole 2;

[0022] A fixing structure includes fixing rods 4 arranged on the side wall of the fixing ring 3. Each fixing rod 4 penetrates through the side wall of the fixing ring 3 and extends to the outside of the fixing ring 3. One end of each fixing rod 4 located outside the fixing ring 3 is fixedly connected with a rotating block 6. One end of each fixing rod 4 located inside the fixing ring 3 is fixedly connected with a fixing clamping plate 8. Each fixing clamping plate 8 is arc-shaped. Rotate the rotating block 6 to move the fixing rod 4, so that the fixing clamping plate 8 moves accordingly, and the fixing clamping plate 8 clamps and fixes the rotating rod. Connect the rotating rod with the fixing clamping plate 8, so that the rotating rod is also fixed together with the fixing ring 3 and the fixed grinding wheel 1. At this time, the rotation of the rotating rod will drive the fixed grinding wheel 1 to rotate together, so as to perform grinding;

[0023] A threaded sleeve 5 is fixedly sleeved on each fixing rod 4. Each threaded sleeve 5 penetrates through the fixing ring 3, and the threaded sleeve 5 and the fixing ring 3 are connected to each other by threads. A fixing spring 7 is rotatably connected to one side side wall of each rotating block 6. Each fixing spring 7 is respectively sleeved on the outside of the corresponding fixing rod 4, and the end of each fixing spring 7 is fixedly connected to the side wall of the fixing ring 3. When the fixing rod 4 rotates, the threaded sleeve 5 fixedly sleeved on the outside of the fixing rod 4 will rotate accordingly. Under the action of the threads, the threaded sleeve 5 will move when rotating, pushing the fixing clamping plate 8 to move. At the same time, when the threaded sleeve 5 moves, the fixing spring 7 will be deformed;

[0024] Fixing grooves 11 are opened at both ends of each fixing clamping plate 8. A fixing shaft 12 is rotatably connected between the inner walls of each fixing groove 11. An auxiliary clamping plate 9 is fixedly sleeved on each fixing shaft 12. Both ends of each auxiliary clamping plate 9 are fixedly connected with a torsion spring 13. Each torsion spring 13 is respectively sleeved on the outside of the corresponding fixing shaft 12, and one end of each torsion spring 13 away from the auxiliary clamping plate 9 is respectively fixedly connected with the inner wall of the corresponding fixing groove 11. During the process of the fixing clamping plate 8 moving to fix and clamp the rotating rod, the auxiliary clamping plate 9 will first come into contact with the rotating rod. The acting force between the two makes the auxiliary clamping plate 9 move outward, so that the torsion spring 13 is deformed. The elastic force of the torsion spring 13 presses the auxiliary clamping plate 9 on the surface of the rotating rod to further fix the rotating rod and improve the fixing effect;

[0025] An installation block is fixedly installed on the side wall of the fixed clamping plate 8. The installation block is threadedly connected to the corresponding fixed rod 4, so that the fixed rod 4 can be conveniently disassembled from the fixed clamping plate 8; anti-slip lines are provided on the outer wall of each rotating block 6, and rounded corners are provided on the side wall of each rotating block 6 to facilitate the rotation of the rotating block 6; a plurality of fixed teeth 10 are fixedly connected to the side wall of each fixed clamping plate 8 close to the inner side of the fixed ring 3 to increase the friction between the fixed clamping plate 8 and the rotating rod, so that its fixation is more firm.

[0026] In the present utility model, when the device is in use, first install the fixed grinding wheel 1 on the grinding machine through the fixed ring 3. The rotating rod of the grinding machine passes through the fixed ring 3 and extends to the installation hole 2. At the same time, rotate the rotating block 6 so that the fixed rod 4 rotates accordingly. When the fixed rod 4 rotates, the threaded sleeve 5 fixedly sleeved on the outer side of the fixed rod 4 will rotate accordingly. Under the action of the thread, the threaded sleeve 5 will move when rotating, pushing the fixed clamping plate 8 to move. At the same time, when the threaded sleeve 5 moves, it will deform the fixed spring 7, so that the fixed clamping plate 8 moves accordingly, so that the fixed clamping plate 8 clamps and fixes the rotating rod, connecting the rotating rod and the fixed clamping plate 8 together. Moreover, when the fixed rod 4 rotates, the threaded sleeve 5 fixedly sleeved on the outer side of the fixed rod 4 will rotate accordingly. Under the action of the thread, the threaded sleeve 5 will move when rotating, pushing the fixed clamping plate 8 to move. At the same time, when the threaded sleeve 5 moves, it will deform the fixed spring 7, so that the rotating rod is also fixed together with the fixed ring 3 and the fixed grinding wheel 1. At this time, the rotation of the rotating rod will drive the fixed grinding wheel 1 to rotate together, so as to perform grinding. Reverse rotation of the rotating block 6 can separate the fixed ring 3 from the rotating rod. When the threaded sleeve 5 disengages from the rotating rod, the elastic force of the fixed spring 7 pushes the rotating block 6 and other structures outward, so as to facilitate their separation from the rotating rod for replacement.

[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
