[0002] Burners are a general term for devices that spray fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application areas. They are mostly made of corrosion-resistant and high-temperature resistant materials such as stainless steel or titanium. A pipe will be installed at one end of the burner to facilitate the spraying of fuel and air through the pipe. In the process of processing the burner pipe, the pipe mouth needs to be polished.

[0003] According to a Chinese patent with publication number CN213970325U, a pipe opening grinding device for PVC pipes is disclosed. The utility model first puts the PVC pipe to be ground into the clamping rod, and makes the PVC pipe not exceed the grinding groove, then rotates the insertion rod, and then moves the inside of the clamping rod toward the middle to squeeze and fix the PVC pipe to be ground, and then pushes the insertion rod to slide forward horizontally, close to the grinding box, and grinds the PVC pipe to ensure that the polished PVC pipe opening is in a uniform plane.

[0004] Regarding the above-mentioned disclosed patent content, since a grinding head is provided to grind the pipe mouth, when it is necessary to grind pipes of different inner diameters, grinding heads of different sizes need to be used, so the grinding head needs to be replaced. The replacement process is to remove the grinding head and replace it with another grinding head that is compatible with the inner diameter of the pipe, so that pipes of different inner diameters can be polished. The process of replacing the grinding head is relatively cumbersome. Most grinding heads are installed on a rotating structure by bolts. The bolts need to be installed and removed during disassembly and assembly, which is time-consuming, making it inconvenient to quickly replace the grinding head. Utility Model Content
