The invention relates to the technical field of measuring instruments, and discloses a barrel straightness measuring method and device.The barrel straightness measuring device comprises a main body, supporting legs are fixedly connected to the four corners of the bottom of the main body respectively, two vertical plates are fixedly connected to the side, away from the supporting legs, of the main body, and the two vertical plates are symmetrically distributed with the middle of the main body as the center; the side, away from the main body, of the vertical plate is fixedly connected with a fixing ring. According to the invention, the fixed block I moves downwards and drives the piston box to move together, and the top block pulls the piston plate to enable the piston plate to move backwards in the piston box to generate suction force in the process of moving downwards of the fixed block I, so that the barrel is fixed, and the movement or vibration of a part in the process of measuring the part by the measurin
