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, and specifically to a tool assembly 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. The main thing is that the axial flow pump is placed in the water and the thrust generated by the high-speed rotation of the blades is used to lift water. The current axial flow pump blades have the following defects: [0003] (1) The machining 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 that the blade clamping in the blade processing It seems ve...
