Specific embodiment
Below in conjunction with FIG. 1 to FIG. 5, by preferred embodiment to technology contents of the invention, construction feature, reached purposeAnd effect is described in detail.
The manufacturing method of non-linear arc T tail provided by the present invention comprising the steps of:
S1, grinding is carried out to blank material, to form the blank shape of rectangular shape, as adding for subsequent handlingWork positioning datum；
The tooling that S2, production are matched with the blank shape in S1, position reference and pressing device as subsequent handling；And by blank shape assembly in the tooling, which plays the role of Set and Positioning；
It is S3, equal using up and down two sides (first side and second side) of the five-axis NC machine center to blank shapeRoughing is carried out, arc empennage is preliminarily formed；
S4, the first side of arc empennage is finished；
S5, the first side of arc empennage is fixed in tooling, the second side of arc empennage is finished；
S6, using wire electric discharge machine method, slotted to arc empennage, aperture and cut off processing；
S7, arc empennage is positioned using drill jig, and bores side through-hole to it, obtain the arc empennage completed the process.
As shown in Figures 2 and 3, in the S2, the groove matched with blank shape 2 is offered in tooling 1, by blankThe end insertion of shape 2 is arranged in the groove of the tooling 1, and is fixed by pressing plate 3.
In the S2, blank shape 2 is on the basis of upper and lower side, two sides side and non-processing end face and tooling1 groove matches, and fit tolerance is within 5.
In the S2, the side wall and bottom surface of the groove of tooling 1 have positioning function, it is ensured that blank shape 2 is addingWork becomes the positioning accuracy during arc empennage；Wherein, the recess sidewall control blank shape 2 of tooling 1 is in clampingX, the positioning of Y-direction；The positioning of Z-direction of the bottom portion of groove granule surface contral blank shape 2 of tooling 1 in clamping.
In the S3, after first side and second side to blank shape 2 complete roughing, single side surplus need to be retained0.1, to guarantee rigid requirements.
In the S4 and S5, after first side and second side to arc empennage complete finishing, it need to ensure to reachThe precision of design requirement.
As shown in figure 4, the first side of arc empennage 4 to be fixed on to the groove of tooling 1 using solid gum in the S5On, the arc empennage of thin-walled can be prevented in process due to vibrating caused by rigidity deficiency.
In the S6, comprising the following steps:
S61, the first passage: the root notches of processing arc empennage form root shape, by live on arc empennageIt drills wire hole and slots at intermediate position and realize；
S62, the second passage: the inner hole and second side shape of processing arc empennage pass through the centre drill in arc empennageIf through-hole, and cut off the realization of the half shape in second side；
S63, third passage: cutting off the remaining shape of the first side of arc empennage, outside the circular arc by arcuately empennageShape connect it is flat after cut off the remaining shape of the other half side wall and realize.
It is described connect it is flat specifically refer to complete to dock with the cambered surface of machined completion, form the surface of same radian, it is ensured thatCutter trade is not seen.
As shown in figure 5, the root shape 6 of drill jig 5 and arc empennage 4 exactly matches, and uses arc tail in the S7The tip 7 of the wing 4 and drill jig 5 are fixed, carry out lateral through aperture processing, to finally obtain after processing is completed non-as shown in Figure 1Linear arc T tail.
In conclusion the manufacturing method of non-linear arc T tail provided by the present invention, is pressed from both sides by the tooling of design specializedTool is positioned, and realizes that blank part facilitates the Set and Positioning of accurate stable in numerical control processing；And select reasonable biteTool and machined parameters, it is ensured that the realization of efficient high-accuracy process；In conjunction with Electric Discharge Wire-cutting Technology, the manufacture of part is realizedProcess.
The present invention is a kind of side that may be implemented to carry out the labyrinth of thin-walled, non-linear cambered surface five-axle linkage processingBlank material assembly in tooling and is finally mounted on numerical control table, NC table by method, with numerical control integrated technique substitution common machineBed is processed, to realize the high-precision processing and manufacturing of thin-walled parts.Since the present invention uses clamped one time positioning process, haveEffect is avoided because positioning cumulative errors caused by multiple clamping, not only the consistency of guarantee converted products, the stability of quality, andAnd make to process simpler easy to operate, effectively improve processing quality and processing efficiency.The present invention is with processing high efficiency and reliablyProperty and continuous production, can promote become can be commonly used to thin-walled, non-linear cambered surface labyrinth highly-efficient processing handSection.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentionedDescription is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the inventionA variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
