Abstract
The invention provides a guide vane body oil hole machining method, which is characterized by comprising the following steps: firstly placing and fixing a flat plate with a proper size on a boring lathe guide rail and scribing a straight line which is collinear with a main shaft of a boring lathe on the flat plate; then placing a guide vane body on the flat plate by overlapping an oil hole central line mark marked on the outer circular edge of a guide vane body flange with the straight line previously scribed on the flat plate; and finally, vertically moving the center of the main shaft of the boring lathe clamped with a drilling bit to the boss direction for a corresponding distance from the plane of the flat plate according to the vertical distance from the central line of an oil hole in a boss to the flange plane in a design drawing, wherein a short drilling bit is firstly used and then changed into a long drilling bit after a certain depth is reached during machining. The method is simple, easy and efficient, a special tool clamp is not required to be designed additionally, and the production cost is reduced.
Description
Technical field
The present invention relates to the processing field, the tool fallow land refers to a kind of diffuser oilhole processing method.
Background technology
The diffuser oilhole is to carry lubricating oil by this oilhole to the diffuser central rotating shaft, plays lubricated, cooling-down effect, guarantees that main shaft normally moves.Because the diffuser oilhole runs through whole thick wing type blade, if in process, machining deviation appears in the oilhole angle, then the blade deflection can be drilled, and the blade leakage of oil takes place during fuel feeding, causes product integral body to be scrapped, and causes the tremendous economic loss.Existing diffuser oilhole processing high-end Digit Control Machine Tool or the complicated auxiliary mould anchor clamps of adopting adopt high-end Digit Control Machine Tool requirement processing Personnel Skill Levels height more, and production cost is also high.
Summary of the invention
The purpose of this invention is to provide a kind of simplely, do not need the oilhole processing method of complex tool equipment.
A kind of diffuser oilhole processing method is provided, it is characterized in that: at first the flat board of suitable dimension is put on the boring machine guide rail and fixing standardized straight line with the boring spindle conllinear on flat board; Then diffuser is placed on the flat board with drawing in advance to overlap at the straight line on the flat board by the oilhole center line mark that is marked on the diffuser flange outer circumferential edge; Last according to the vertical range of design drawing convexity table oil centerline hole apart from Flange Plane, there is the boring spindle center of drill bit vertically to move corresponding distance to the boss direction from plate level clamping, add and use earlier stub drill man-hour, changing behind the certain depth is long drill bit.
The invention has the advantages that: this method mainly is with boring spindle center line and the straight line conllinear of drawing in advance on flat board, according to the vertical range of design drawing convexity table oil centerline hole apart from Flange Plane, there is the boring spindle center of drill bit vertically to move corresponding distance to the boss direction from plate level clamping.This method is simple, easy row, efficient, and frock clamp that needn't the otherwise designed special use saves production cost.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is a kind of diffuser oilhole of the present invention processing structure schematic diagram;
Fig. 2 is a kind of diffuser oilhole processing of the present invention schematic top plan view;
Fig. 3 is a kind of diffuser oilhole processing of the present invention cut-away illustration.
The specific embodiment
By reference to the accompanying drawings this method is further described:
Shown in Figure 1 is diffuser 1, flat board 2 and drill bit 3, the line that intersects by boss and diffuser 1 flange outer circumferential edge shown in Figure 2 is the oilhole center line, this boss corresponding position is a thick wing type blade, diffuser 1 center line and oilhole center line and diffuser 1 flange outer circumferential edge have two intersection points respectively, measure the chord length between these two intersection points respectively in design drawing; By the design drawing requirement diffuser 1 blank flange cylindrical is worked into design size, find diffuser 1 horizontal center line accurately and make horizontal line mark (two) in diffuser 1 flange outer circumferential edge by scribble method, make oilhole center line mark (two) by the chord length of measuring in diffuser 1 flange outer circumferential edge, the line of this mark is the projection of oilhole center line on dull and stereotyped 2.
Fig. 2, the flat board 2 of suitable dimension shown in Figure 3 is placed on the boring machine guide rail and fixes, standardized straight line with the boring spindle conllinear on flat board, diffuser 1 is placed on dull and stereotyped 2 and fixes with drawing in advance to overlap at the straight line on dull and stereotyped 2 by the oilhole center line mark that is marked on the diffuser 1 flange outer circumferential edge, boring spindle center line and the straight line conllinear of drawing in advance on dull and stereotyped 2, according to the vertical range of design drawing convexity table oil centerline hole apart from Flange Plane, clamping there is the boring spindle center of drill bit vertically move corresponding distance to the boss direction from dull and stereotyped 2 planes, add and use earlier stub drill man-hour, changing behind the certain depth is long drill bit.
Though above shown detailed embodiment of the present invention, apparent, those skilled in the art is under prerequisite of the present invention, can carry out the part modifications and changes; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, is not to be limitation of the present invention, has a kind of diffuser oilhole processing method of above-mentioned technical characterictic, all falls into protection domain of the present invention.
