[0002] Aviation aluminum alloy tubular castings are a type of aluminum alloy castings specially used in the aviation field. They have a specific shape and structure and are usually used to manufacture key components of airplanes, helicopters and other aircraft. The stability of the castings needs to be ensured during processing by aluminum cutting machines. The clamping tooling can provide stable support and positioning to prevent the aviation aluminum alloy tubular castings from moving or deforming during processing, thereby avoiding the failure of aviation aluminum alloy tubular casting processing.

[0003] The existing clamping tooling is basically composed of two telescopic cylinders and two clamping blocks. When the aviation aluminum alloy tubular casting enters the aluminum cutting machine, the two telescopic cylinders extend respectively to drive the two clamping blocks to move relative to each other, thereby completing the clamping and limiting of the aviation aluminum alloy tubular casting and preventing the aviation aluminum alloy tubular casting from being displaced during processing inside the aluminum cutting machine.
