| description | The invention particularly relates to a heavy-load friction stir welding stirring needle withdrawing device which is installed at the rear end of a heavy-load friction stir welding main shaft (2), and a heavy-load friction stir welding stirring head (3) is installed at the front end of the heavy-load friction stir welding main shaft (2). The heavy-load friction stir welding stirring head (3) comprises a stirring needle (6) and a shaft shoulder (5) which are of a split structure. The heavy-load friction stir welding stirring needle withdrawing device comprises a rotary separating mechanism, a planetary lead screw servo driving mechanism and a stirring needle withdrawing shaft (9). And the planetary screw servo driving mechanism drives the stirring needle withdrawing shaft (9) to drive the stirring needle (6) to continuously and stably withdraw towards the interior of the shaft shoulder (5) under the cooperation of the rotary separation mechanism.
