Friction stir welding clamping structure of new energy electric control shell

The invention relates to the technical field of friction welding, and discloses a friction stir welding clamping structure for a new energy electric control shell, which comprises a workbench, a fixing tool is arranged on the workbench, a plurality of pressing pieces are arranged on the fixing tool, and pressing blocks I are arranged on the pressing pieces; a plurality of pressing pieces which need to be lifted when the welding head passes through are all provided with downward pressing pieces, and each downward pressing piece further comprises a second pressing block and a connecting block; the problems that after a pressing piece is lifted for a welding head to pass through, when the pressing piece is pressed on a welding piece again, chippings can be pressed on the welding piece, the chippings can be attached to the welding piece, and the chippings pressed on the welding piece can cause certain scratches to the surface of the welding piece due to the fact that the pressing force of the pressing piece is la
