A tire X-ray inspection machine and a centering spinning method thereof. The tire is expanded and centered outwards from the bead portion of the tire by using a drive roller (7, 8) and the tire is driven to spin, so as to improve stability of the tire during high-speed spin, thereby improving imaging quality in X-ray inspection and enhancing X-ray inspection quality and efficiency. The tire X-ray inspection machine comprises a lead chamber (1) for inspecting the tire in an enclosed manner, a delivery device (2), a roller platform (3), an X-ray emission device (4), an X-ray receiving device (5), and a centering spinning device (6). The centering spinning device (6) has at least one driving roller (7), for driving the tire to spin in a inspection process by pressing the bead of the tire; the driving roller (7) is provided on a first slide rack (9), and a first drive device for driving the driving roller (7) to axially spin is mounted on the first slide rack (9). The centering spinning device (6) also has at least one driven roller (8), for axially spinning with the tire in the inspection process by pressing the bead of the tire. The first slide rack (9) and a second slide rack (10) are separately connected to a guide rail (11) in a slide manner through the same transmission mechanism, and the first slide rack (9) or a second slide rack (10) is connected to a second drive device at one side. |
