The present disclosure belongs to the technical field of friction stir welding devices. An objective of the present disclosure is to provide a double-head double-sided high-efficiency friction stir welding device, which comprises a base; a pair of columns arranged on the base; an upper beam connected with the top ends of the columns, wherein an upper head is arranged on the upper beam; a lower beam connected between the lower ends of the columns, wherein a lower head is arranged on the lower beam and corresponds to the upper head up and down, the columns, the upper beam and the lower beam form a gantry having an integrated structure, the upper head and the lower head can move by a drive device and a transmission mechanism along an X-axis, a Y-axis and a Z-axis and rotate along the Z-axis, movement of the upper head and the lower head along the X-axis and the Y-axis is driven by utilizing a linear motor or a motor-driven rack-and-pinion mechanism in a screw guide rail or rack-and-pinion guide rail transmission manner, movement of the upper head and the lower head along the Z-axis can utilize a manner such as servo electric cylinder transmission, hydraulic transmission, screw transmission, rack-and-pinion transmission and the like, rotation of the upper head and the lower head along the Z-axis can utilize a manner of combining an electric spindle or a mechanical spindle with a motor, and the motor can be a servo motor or an asynchronous motor.
