The processing unit (plant) of this axial-flow pump impeller spherical outside surface of the present utility model is by lathe tool, knife bar and feed mechanism constitute, wherein, described lathe tool is fixedly installed on an end of described knife bar, be provided with a linear slot in the body of rod of knife bar vertically, be provided with a bearing pin in the described linear slot, be connected with a knife bar push rod on the described bearing pin, described knife bar push rod is connected with described feed mechanism, the other end of knife bar is provided with an arbor holder, one end of described arbor holder is provided with an axle, described axle is axial perpendicular to arbor holder, be provided with in the other end of knife bar one perpendicular to cutter spindle to connecting hole, axle is passed described connecting hole.
Further, the external diameter of described axle cooperates with the internal diameter of described connecting hole.
Further, the width of described linear slot cooperates with the external diameter of described bearing pin.
Further, has a bending in the axial direction in the middle part of the described knife bar.
Further, described knife bar push rod is made of a member with Y type headtree, and the headtree of described member is connected with the two ends of described bearing pin respectively.
Further, described feed mechanism is made of the cutter platform of lathe, and described cutter platform is arranged in the lathe, and the other end of described arbor holder is connected by the tailstock of Morse's taper structure and lathe.
Operation principle of the present utility model is: with axial-flow pump impeller device to be processed to lathe, the center of the axle of arbor holder one end adjusted to the centre of sphere of impeller outer sphere overlap, after the rotation of lathe drives impeller, drive the cutter platform moving linearly that slip crate drives lathe by shaking feeding handwheel or machine, the cutter platform drives lathe tool by knife bar impeller is cut.The cutter platform promotes knife bar and rotates around the axle of arbor holder end in the process of advancing, lathe tool with the axle of arbor holder end be the center of circle along circular motion, thereby realize the processing of spherical outside surface.The axle center is exactly to process the radius of sphere to the distance of lathe tool point of a knife.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged on knife bar one end with lathe tool, and the knife bar other end is fixed on the centre of sphere place that processes sphere, utilizes the cutter platform driving knife bar of lathe to move in a circle, and can process required spherical outside surface easily on impeller, and is simple in structure, easy to manufacture; Because arbor holder is installed on the tailstock tool, the centre of gyration of workpiece and the center of cutter overlap, and tool setting is convenient, the tailstock handwheel that only needs to rotate lathe with the axle center vertically a direction move to the workpiece sphere centre of sphere and get final product; The dimensional measurement of processing spherical diameter is convenient.Need only measure the distance of axle center, just know the diameter of processing sphere to point of a knife; The arbor holder afterbody adopts Morse's taper and tailstock tool to cooperate, and the knife bar push rod is fixed on has just finished whole installation adjustment work on the cutter platform, need not other adjustment, install easy to adjust; Because push rod is installed on the cutter platform, can hang feed and realize power feed, so machined surface roughness controls easily, because processing sphere principle does not have error, therefore the spherical shape error that processes is very little again, crudy is good.
