Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing tool for axial flow pump parts and a processing method for the parts, in particular to a tooling combination for processing axial flow pump blades and a precision processing method for axial flow pump blades . Background technique [0002] In water conservancy projects, the axial flow pump is different from other water pumps. It mainly puts the axial flow pump in the water and uses the thrust generated by the high-speed rotation of the blades to lift water. The blades of the axial flow pumps currently used have the following defects: [0003] (1) The processing accuracy is not high, and the blade deformation is large, mainly due to the position error caused by the part clamping, the part deformation caused by the part clamping, and the deformation caused by the material stress release. It can be seen from this that the blade clamping in the blade processi...
