Abstract
The invention relates to the field of machining, in particular to an axial flow pump blade machining method. The method includes the following steps that a process circular truncated cone plane and a blade neck plane on an outer ring are milled on a boring mill; center holes in two ends are drilled through the boring mill; by means of a special blade clamp, the center holes in the two end tops are positioned and clamped, and the outer ring, the planes, a step face and an inner spherical face are turned to required sizes; a blade is clamped through a special tool for blade numerical control milling, the center holes are positioned, and a work curved face and a back face curved face of the blade are milled to required sizes on a five-axis linkage numerical control milling machine; a drilling die is used for drilling four countersunk bolt holes in the root portion of the blade; a process circular truncated cone on the outer ring of a sphere is removed in a milling mode on the boring mill; the blade is assembled and fastened through bolts, and the outer spherical face of the blade is turned by a numerical control lathe to a required size. The method can greatly improve machining quality of workpieces, can guarantee that the machined workpieces completely meet the design requirements, improves production efficiency, and reduces production cost.
Description
Technical field
The present invention relates to field of machining, be specifically related to axial flow pump blade inner processing method.
Background technology
What axial flow pump blade inner produced employing is hot investment casting molding, material is ZGlCrl8Ni9 rustless steel, what adopt before spoon of blade work surface and the back side is the processing technique of sanding and polishing, but blade surface is irregular complex-curved and Curvature varying is big, not only labor intensity of polishing is big, inefficiency, also cannot ensure that the curve form after polishing processing meets the requirement that designs a model. Owing to blade casting deformation and shrinkage factor are inconsistent, cause that each spoon of blade thickness and aerofoil profile size are difficult to ensure that, and affect the total quality of wheel member.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of crudy that can greatly provide workpiece, and can guarantee that the workpiece after processing complies fully with designing requirement, improves production efficiency, reduces the axial flow pump blade inner processing method of production cost.
Axial flow pump blade inner processing method of the present invention, comprises the following steps:
The first step, the technique round platform plane on the flat cylindrical of milling and blade cervical region plane in lying bed;
Second step, three-dimensional coordinate measuring instrument is utilized to check essence casting blade Cast blanks surface allowance and casting deflection, then the multiple point coordinates on three-coordinates measuring machine scanning record blade curved surface are utilized, determine the centrage of blade, find out the central point of blade blank cylindrical technique round table surface, and root of blade position plane central point, finally bore sample punching;
3rd step, upper boring machine bores two ends centre bore;
4th step, utilizes blade special fixture, and top, two ends centre bore realizes location clamping, and turning and plane, step surface and Internal Spherical Surface are to requiring size;
5th step, utilizes blade digital control milling special tooling clamping blade, and centre bore positions, and mills out blade working curved surface and back curve only requires size on five-shaft linkage numerically controlled machine;
6th step, utilizes drill jig to bore four dormant bolt holes of root of blade;
7th step, mills technique round platform on ball cylindrical on boring machine;
8th step, according to assembling figure, by blade, impeller base, blade pressing plate assembles, and adopts bolt to fasten, and joins Propeller Blade sheet spherical outside surface to requiring size at numerically controlled lathe.
The present invention can greatly provide the crudy of workpiece, and can guarantee that the workpiece after processing complies fully with designing requirement, improves production efficiency, reduces production cost.
