The invention discloses a wheel runout detection device. A synchronous gear B (17) is mounted on the output shaft of a servo motor (18), a synchronous gear A (15) is connected with the synchronous gear B (17) via a synchronous belt (16), a flange (9), an expansion sleeve (11) and a cylinder (13) are mounted on a flange plate (8), and two ends of a connecting shaft (14) are respectively connected with the output shaft of the cylinder (13) and an expansion core (10). The cylinder (13) pulls the expansion core (10) down, and through cone surface fits between the expansion core and the expansion sleeve and between the expansion core and the flange plate, the outer diameter of the expansion sleeve (11) is expanded, so that the central hole of a wheel is tightened and high-precision radial positioning of the wheel is realized. The servo motor (18) drives the flange (9), the expansion sleeve (11) and the wheel to rotate via the synchronous gear A (15), the synchronous belt (16) and the synchronous gear B (17). The device can meet the requirement of wheel runout detection in use, and has the characteristics of ideal effect, high efficiency and high working safety and reliability.
