Abstract
A device for processing an axial flow pump impeller chamber inner-sphere is provided, which comprises a lathe cutter, a cutter arbor and a feed mechanism. The lather cutter is fixed on one end of the cutter arbor inside which is provided with a straight-line groove hole along the axle direction. The straight-line groove hole is internally provided with a pin shaft on which is connected with a cutter arbor push-rod. The cutter arbor push-rod is connected with the feed mechanism. The other end of the cutter arbor is connected with a cutter arbor support base via a mandrel. Arranging the axial flow pump impeller indoor component to be processed on the lathe and adjusting the center of the mandrel on the sphere center of the impeller chamber inner-sphere, the lathe stand will drive the lathe cutter to exercise the cutting inside the impeller chamber via cutter arbor. The cutter arbor rotates around the mandrel and the lathe moves around the sphere by taking the mandrel as the center so as to realize the processing of inner sphere. The utility model drives the cutter arbor to practice circle movement by using the lathe cutter stand and processes the inner sphere needed on the axial flow pump impeller chamber components. The utility model has the advantages of being simple in structure, easy in manufacturing and convenient in cutting and control of processing the product with coarse surface with small error in the sphere shape that has been processed as well as good processing quality.
