Claims6
A double-head double-sided friction stir welding device, comprising:
- 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, each pair of the upper head and the upper beam and the lower head and the lower beam is connected through a rotary shaft, and welding angle adjustment can be conducted on the upper head and the lower head through the rotary shafts;
- at least one worktable connected with a horizontal surface of the base, wherein the worktable is located between the upper head and the lower head, and the worktable and the gantry can relatively move to achieve welding;
- vision sensors mounted on the upper head and the lower head and used for identifying the weld;
- and
- a CNC controller used for controlling operations of the gantry, the upper head, the lower head, the worktable and the vision sensors, wherein a rail groove is formed in the upper surface of the base, and the gantry can conduct horizontal reciprocating movement along the rail groove under the drive of the linear motor or the motor-driven rack-and-pinion mechanism to form relative movement with the fixed worktable.
