Finally, the driving motor 23, the turntable motor 6 and the abrasive belt motor 2 are started simultaneously, the driving motor 23 drives the driving belt wheel 24 and the driven belt wheel 26 to rotate, so that the automatic polishing device for the inner wall surface of the pipe barrel moves along the axial direction of the pipe barrel; the abrasive belt motor 2 drives the driving belt wheel 5 to rotate so as to drive the abrasive belt 41 to rotate and polish the inner wall surface of the pipe barrel, and meanwhile, the turntable motor 6 drives the turntable 9 to rotate so as to drive the supporting structures 103 to rotate along the circumferential direction of the central shaft 12, so that the abrasive belt 41 can polish and polish the whole inner wall surface of the pipe barrel. It should be noted that the abrasive cloth can be arranged on the supporting wheels of the two supporting structures without the abrasive belt as required to ensure the grinding precision and smoothness of the inner wall surface of the pipe barrel.
