Multi-angle rotating automatic mechanical arm clamping mechanism

The invention relates to the technical field of mechanical arms, and particularly discloses a multi-angle rotating automatic mechanical arm clamping mechanism which comprises a connecting cylinder mounted on a mechanical arm body, a plurality of groups of clamping jaws are rotationally connected to the connecting cylinder, and the plurality of groups of clamping jaws are distributed on the periphery of the connecting cylinder in a circumferential array manner; and a driving assembly is arranged in the connecting cylinder. Therefore, in the actual use process, the driving assembly drives the multiple sets of clamping jaws to synchronously rotate, the multiple sets of clamping jaws synchronously get close to one another on the circumferential side of the workpiece, a more stable sealed space is formed for the clamped workpiece, and then the stability of the clamping mechanism during workpiece clamping can be improved; compared with the prior art that only clamping plates on the two sides are close to each other
