Multi-station synchronous hollow rotating platform device

The utility model discloses a multi-station synchronous hollow rotating platform device which comprises a base assembly, a driving motor, at least two hollow rotating assemblies installed on the base assembly in the length direction, a belt wheel assembly and a plurality of connecting shafts, and each hollow rotating assembly comprises a 90-degree corner device and a hollow rotating platform. The 90-degree angle turning devices are driven by connecting shafts, the adjacent connecting shafts are connected through couplings, and a plurality of couplings and connecting shafts used for connecting the 90-degree angle turning devices form a connecting shaft assembly. The driving motor drives the connecting shaft assembly to rotate through the belt wheel assembly, and then the at least two hollow rotating assemblies operate synchronously. Compared with the technical scheme that a synchronous belt directly drives rotation in the prior art, the precision of the synchronous belt is poor, and the synchronization precisi
