A method for processing a thin-walled structure part of a cantilever

Abstract

The application discloses a processing method for welding a cantilever thin-wall structure part, wherein a supporting wheel moving with a tool is arranged on the back of the processed surface of a workpiece to limit the swing and deformation of the workpiece; the processing method comprises a large supporting plate, a middle supporting plate and a small supporting plate, the large supporting plate is arranged on a guide rail of a machine tool bed, the middle supporting plate is arranged on a guide rail of the large supporting plate, the small supporting plate is arranged on a guide rail of the middle supporting plate, the large supporting plate is perpendicular to the middle supporting plate, and the moving direction of the small supporting plate is consistent with that of the large supporting plate; a turret is arranged on the small supporting plate; a tool holder is arranged on the turret, a tool is fixed on the tool holder, and the cutting edge of the tool is in contact with the surface to be processed; a wheel frame is also arranged on the turret, a supporting wheel is arranged on the wheel frame, and the supporting wheel is in abutment with the back of the processed surface of the workpiece. The processing method has the advantages that the mechanical limiting is realized by using the roller during the processing of the part, the stress influence during the turning of the tool can be accurately offset, the deformation of the part in the processing process is controllable, and the wall thickness size is qualified.
