In a broad sense, the propeller also comprises a pole, a paddle, a scull, a fiber, a sail, etc. which drive the ship forward by means of manpower or wind power.
When the existing propeller shell is welded with an inner seam or polished and polished internally, the propeller shell is usually placed on a supporting seat, and rotates after polishing, and then the other part is processed;
as disclosed in chinese patent publication No. CN 218194772U, a tooling fixture for processing a fuel tank of an aircraft propeller includes at least two process rings, wherein the process rings are used for fixedly sleeving the fuel tank; at least two pedestals for placement under the fuel tank, with the pedestals corresponding under each of the process rings; the bearing seats are respectively arranged on two sides of the axis of the fuel tank on the base, the bearing wheels are rotatably arranged on the bearing seats, and annular grooves for placing the process rings are formed in the circumferences of the bearing wheels; the clamping seats are respectively arranged on two opposite sides of the bearing seat, which correspond to the process ring, and the clamping seats are provided with clamping wheels for rolling and clamping the process ring.
Although the shell of the propeller of the aircraft belongs to a cylinder shape, and both ends of the propeller of the ship are in a round table shape, the processing modes are the same; however, when the inner wall of the shell of the propeller is subjected to welding seam treatment or polishing, the scaffold is required to ascend, the scaffold is quite unstable when the scaffold is additionally arranged in the propeller, and when a worker processes the top in a standing state, welding slag or polished ash can fall into eyes; the staff needs to face upward and lift the arms, so that the working mode is short in duration and is easy to cause arm ache of the staff;
after one part is processed, the scaffold is required to be moved out, then the shell of the propeller is rotated, then the workbench and the scaffold are rearranged, and the scaffold is moved back and forth, so that not only is the labor intensity increased, but also the working efficiency is reduced.
