[0013] The following is combined with Figure 1-3 The specific implementation methods of the utility model are further described.
[0014] A quick-change friction stir welding grinding tool comprises a tool body 1. A tool holder angle safety installation limit groove 13 is provided at the lower part of the outer wall of the tool body 1 along the direction of the main line. A grinding milling cutter holder 2 is installed in the tool holder angle safety installation limit groove 13 and is fastened by a tool holder adjustment locking bolt 9. A grinding milling cutter blade 3 is installed at the bottom of the grinding milling cutter holder 2. A limit step 6 is provided at the middle part of the outer wall of the tool body 1. A locking adjustment bolt countersunk hole 4, a locking bolt through hole 7, a square limit installation hole 11, and a circular positioning hole 12 are provided in the interior of the tool body 1 from top to bottom. A stirring head limit step 10 is provided between the locking bolt through hole 7 and the square limit installation hole 11. A quick-change stirring head 8 is installed in the circular positioning hole 12 and is fastened by the locking adjustment bolt 5 at the top.
[0015] During the friction stir welding process, the milling cutter is driven by the high speed of the equipment to remove the weld flash and burrs while welding.
