Abstract
An inner clamp for a friction stir welding device of an aircraft fuel storage barrel comprises an installing frame. A circle of clamping blocks surround the installing frame and include the multiple clamping blocks A and the multiple clamping blocks B. The number of the clamping blocks A is equal to the number of the clamping blocks B. The clamping blocks A and the clamping blocks B are alternately distributed. The clamping blocks A are connected with lead screws A. The clamping blocks B are connected with lead screws B. The lead screws A are sleeved with nuts A, and the lead screws B are sleeved with nuts B. When the nuts A rotate, the lead screws A can be driven to move in the axial direction of the nuts A. When the nuts B rotate, the lead screws B can be driven to move in the axial direction of the nuts B. When the clamping blocks play an outer supporting role, the end faces of the clamping blocks A abut against the end faces of the clamping blocks B, and therefore a circle can be defined by the clamping blocks A and the clamping blocks B. The inner clamp is simple in structure and convenient to operate.
