Pneumatic clamping rotating device

The invention aims at providing a pneumatic clamping rotating device. The pneumatic clamping rotating device comprises a rack, a clamping mechanism and a rotating mechanism, wherein the rack comprises a first cross beam and a second cross beam, a first connecting block and a fourth connecting block are respectively mounted at the two ends of the first cross beam, a second connecting block and a third connecting block are respectively mounted at the two ends of the second cross beam, the clamping mechanism comprises a first clamping unit, a second clamping unit, a third clamping unit and a fourth clamping unit, which have the same structure, the rotating mechanism comprises a ducted fan, a steering engine and a rotating bracket, the ducted fan is connected with an output shaft of the steering engine through a ducted fan base, the steering engine is fixed to a steering engine base, the steering engine base is fixed to the rotating bracket, and the rotating bracket is fixedly connected with the first cross beam and the second cross beam. The pneumatic clamping rotating device can move and rotate between platforms, broaden the application range of a robot and solve the problems that the original clamping mechanism is poor in stability, low in rotating mechanism speed, incapable of adapting to different heights and the like.
