Abstract
The through flow turbine guide blade axle journal machining comprises clamping the guide blade on the jig, through unit head to install axiality or through working piece to find the axiality, using unit head rotary and cutting to get the high precision guide axle journal. It won't have centrifugal force, without jumping around and journal ovality. It is easy to ensure precision machining with high efficiency.
Description
Technical field
The present invention relates to a kind of method of processing through flow turbine entrance bucket axle journal.
Background technology
The axiality of stator two ends axle journals (or axis hole) is had relatively high expectations, the generally workpiece rotation turning processing on horizontal lathe of the processing method of guide vane teunnion, but for large-scale tubular stator, because the stator shape is special, lay particular stress on big, diffuser differs greatly with rigidity on the vertical both direction in level, and processing rear guide vane axle journal bigger circle often occurs and beats.Therefore adopt this method to add and must select for use man-hour heavy type to lie in bed, but because the restriction of equipment processing ability, when the tubular stator of machining large, the axle journal precision just is difficult to meet design requirement.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, provide a kind of and can not produce centrifugal force, also produce apparatus of processing through flow turbine entrance bucket axle journal and the method that centrifugal force causes the axle journal ovality with regard to not laying particular stress on because of diffuser, machining accuracy guarantees easily, the working (machining) efficiency height.
Purpose of the present invention is achieved through the following technical solutions: method of processing through flow turbine entrance bucket axle journal, and it may further comprise the steps: a, need process stator and be clamped on the stator anchor clamps, stator maintains static; B, the axiality of finding stator two ends axle journal accurately by the installation axiality or the workpiece of left unit head and right unit head; The cutting process of c, the left unit head of employing and rotation of right unit head and feeding, promptly whirling obtains the high guide vane teunnion of coaxial accuracy.
By top narration as can be seen, the present invention has the following advantages: stator stator special fixture clamping, because workpiece is motionless, just can not produce centrifugal force, just can not beat because of centrifugal force makes each axle journal produce circle yet, with this scheme processing, the axiality between each axle journal will rely on the installation axiality or the workpiece centering precision of cyclone head.On the other hand, because workpiece is motionless, also cause the axle journal ovality with regard to not laying particular stress on generation centrifugal force because of diffuser.Adopt method of the present invention, machining accuracy is guaranteed easily, working (machining) efficiency is also high.
