Positioning fixing plates are welded or left at both ends of the rudder blade blank, and positioning is achieved by inserting the positioning holes on the rudder blade into the precision positioning pins at both ends of the tooling body, and then the rudder blade is fixed and processed through the fixing assembly.

[0010] The upper surface of the tooling body is provided with support grooves corresponding to the support bars one by one, and a height adjustment structure adapted to the support bars is provided in the support grooves. The height of the support bars can be adjusted through the height adjustment structure, so that the rudder blank can be more accurately fitted.
