The utility model discloses a rotary-type wheel airtightness detection machine. The detection machine is formed by a frame, an air cylinder, upper seal, lower seal, a water tank, a motor, a self-made air cylinder and the like. During usage, a wheel is placed on an upper end of the lower seal; a self-made air cylinder A port stops gas supply; a spring makes a guiding flange hold up the wheel from a lower portion; a guiding portion of a top end simultaneously makes the wheel be in the middle. A compaction air cylinder makes the upper seal press a front side of the wheel through a guide pillar II. Simultaneously, compressed air is filled in the self-made air cylinder A port so that a piston drives a cylinder rod and the guiding flange to drop. A elevating cylinder makes the water tank to rise and immerse the wheel through a guide pillar I. The compressed air is filled from a lower end of a hollow shaft and enters into an inner cavity of the wheel through a vent hole above the cylinder. Pressure maintaining is performed for a certain time. Simultaneously, the motor drives the hollow shaft and the wheel to rotate through a synchronous belt. The airtightness can be determined through observing whether there is a bubble.
