It can be classified according to the size of the pipe diameter. It is generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon asphalt, PVC and other materials.

[0003] According to the patent CN217619505U, a three-way pipe inner wall grinding device relates to the technical field of three-way pipe fittings, which solves the existing grinding methods, most of which are manual grinding, thereby reducing the working efficiency of three-way pipe fitting grinding, and manual grinding needs to rely on the operator's experience to work, so that the junior operator can easily damage the three-way pipe fitting, thereby reducing the technical problem of the yield rate of three-way pipe fitting grinding. The utility model includes a processing box, an electric slide rail is fixedly installed on the upper wall of the processing box, and a hydraulic cylinder is fixedly installed on the moving end of the electric slide rail. When the inner diameter of the lateral end of the three-way pipe fitting needs to be ground, the utility model can be used to grind the inner diameter of the lateral end of the three-way pipe fitting. When the outer diameter of the three-way pipe fitting is clamped by the second clamping device, it is convenient to grind the inner diameter of the horizontal end. When the vertical end of the three-way pipe fitting needs to be polished, the inner diameter of the three-way pipe fitting is clamped by the first clamping device, which is convenient for grinding the inner diameter of the vertical end, thereby improving the working efficiency of grinding the inner wall of the three-way pipe fitting. The utility model inventor found that at least the following problems have not been solved in the prior art. Although the above device can grind the inner wall of the three-way pipe fitting, its grinding device part cannot adapt to different inner diameter sizes. When grinding the inner wall of the tee of different sizes, different grinding heads need to be replaced, which is not convenient for improving the overall processing efficiency. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

When the spiral barrel 3 rises, the lifting member 4 can be pushed to rise synchronously. The lifting member 4 drives the lower part of the pushing rod 7 to gradually rise through the first connecting shaft 6. During the rising process of the pushing rod 7, the movable rod 11 will be pushed to gradually expand with the second connecting shaft 10 as the center. At this time, multiple movable rods 11 are synchronously expanded, and the grinding plate 15 and the grinding sand piece 16 at one end of the movable rod 11 are synchronously expanded. The grinding plate 15 and the grinding sand piece 16 can be placed in the inner wall of the pipe for grinding. When the spiral barrel 3 moves downward, the movable rod 11 can be contracted, so as to adapt to the inner diameters of pipes of various sizes.

[0022] For further information, see Figure 5 A connecting member 12 is installed at the lower part of the movable rod 11, and a movable shaft 14 is installed on the connecting member 12. The connecting member 12 is connected to the upper part of the push rod 7 through the movable shaft 14, and the lifting member 4 drives the lower part of the push rod 7 to gradually rise through the first connecting shaft 6.

[0023] It is worth noting that see Figure 5 A connecting hole 13 is opened in the middle of the connecting member 12, and the diameter of the connecting hole 13 is adapted to the diameter of the movable shaft 14. The movable shaft 14 is located inside the connecting hole 13.
