The turntable 4 is a circular disc with 6 larger station mounting holes 2 on which raised structures form stations 42, as shown in fig. 8. The station is used for fixing the hub. The rotation of the turntable 4 is driven by a servo motor. As can be seen from fig. 6, the lower surface of the turntable 4 is supported by the turntable frame 1 in the middle, but the periphery is not supported by the turntable frame to a relatively wide extent, and these unsupported positions are the positions of the stations. The periphery of the rotary disk is provided with a baffle 3, and the center of the rotary disk is provided with a circular mounting hole 5.

An upper frame is arranged on the turntable 4, and as shown in fig. 2 and 5, the upper frame comprises a central frame column 11, a cross beam, a longitudinal beam and a tripod 6. The number of the cross beams and the longitudinal beams can be adjusted according to the requirement.
