The invention provides a pneumatic lifting rotating table, and the rotating table comprises a rotating table main body (1), a hollow main shaft (2), a fixed device (3), a driving device (4), and a lifting device (6). The top surface of the rotating table main body (1) is provided with a first accommodation groove (11), and the bottom surface of the rotating table main body (1) is provided with a second accommodation groove (12). The rotating table main body (1) is also provided with a shaft hole (13) communicated with the first accommodation groove (11) and the second accommodation groove (12). The fixed device (3) comprises a main wheel (31), and the top of the main wheel (31) turns out to form a first end part (32). The bottom of the main wheel (31) is sleeved by a driven wheel (33). The bottom surface of the main wheel (31) is axially provided with a blind hole (312). A side surface of the first end face (32) is provided with a limiting through hole (313) communicated with the blind hole (312). The main wheel (31) passes through the shaft hole (13), and also passes through the blind hole (312) to be rotatingly disposed on the main shaft (2) in a sleeved manner. The rotating table is simple, and is very practical.
