Rotary clamping mechanism

A rotary clamping mechanism comprises a drive system and a clamping system; the drive system is provided with at least a power device and at least a rotating head driven by the power device to rotate; the clamping system is provided with at least a rotating shaft, at least a rotating wheel fixedly connected with the rotating shaft, and at least a clamping device; wherein, the rotating head is matched and connected with the rotating wheel. The rotating head is driven by the power device to rotate; the rotating head is matched and connected with the rotating wheel; the rotating head of the clamping system is connected with the rotating wheel and the clamping device; the rotating head is rotated to drive the rotating wheel, the rotating shaft and the clamping device to rotate together; when different directions of the product need to be welded, the power device is used to indirectly drive the clamping device to rotate to a corresponding position, then the product can be welded; therefore, the utility model achieves multi-directional welding on the processing product and does not need to replace clamps, thereby improving the utilization rate of the rotary clamping mechanism, reducing the working procedures and time and increasing the production efficiency.
