Abstract
The invention relates to a numerically controlled processing method for a thin-walled part with an open lateral groove end, and adopts the technical scheme that a woolen bottom plane and a lateral plane are taken as positioning criteria; firstly, roughing is carried out on the outline of the edge strip on the side with a groove; then, woolen placing is changed in such a manner that the original lateral plane serves as a bottom plate while the original bottom plate serves as a lateral plane, and grooves are also formed by taking the two planes as positioning criteria; during the outline processing of the part, the part of the part except the open end of the edge strip is processed first, the open end of the edge strip is kept in connection with circumferential woolen, the thickness processing of the edge strip is fulfilled under the state, and then the connection between the open end of the edge strip and the woolen is cut off, so as to form the outline of the open end of the edge strip; and the method that the outer side and the inner side of the edge strip are processed in an alternated manner (namely the outer side layer of the edge strip is fulfilled and then the inner side layer of the edge strip is fulfilled) is adopted, and the required thickness of the edge strip is obtained finally after the operation is carried out repeatedly. The method has the advantages that the position of the groove on the outer side of the edge strip is more accurate; the open end of the edge strip meets the product requirement; and the favorable surface roughness of the edge strip is guaranteed.
Description
Technical field
The invention is mainly applicable to adopt plate digital control processing, and fluted outside edge strip, edge strip termination opens wide, and edge strip thickness≤2mm, the part of height > 40mm.
Background technology
At aviation field, fluted for outside, termination opens wide, and thickness≤2mm, the problem existing in the edge strip part processing of height > 40mm is: first, outside edge strip, groove and woollen baseplane spacing are less, if directly use machine tool chief axis pivot angle machined grooves on platen, lathe headstock can interfere with workbench, therefore processing this type of edge strip outside, to be with reeded part be all to using woollen baseplane and side plane as positioning datum, process all sites except groove, then use square chest or the padded part of other working position apparatuses, the datum hole of usining part baseplane again and having processed is as groove outside positioning datum processing edge strip.Employing the method processing, workman needs lifting station utensil, has increased production time, and variation has occurred the positioning datum that machined grooves adopts, and affect the accurate of groove location.Secondly, the part that edge strip termination opens wide is all to adopt first processing parts profile, be that first cutting-off part and border woollen are connected to form part largest contours, the method processing of rear processing edge strip thickness, the method there will not be problem when edge strip thickness G reatT.GreaT.GT 2mm or edge strip height≤40mm, but when edge strip thickness≤2mm and height > 40mm, the steadiness that edge strip is opened wide end reduces, work in-process can produce larger vibration, easily make the edge strip thickness at this place be less than the minimum dimension that product design requires, become defective work.The 3rd, while processing high thin edge strip, be all that both sides all adopt the mode of the processing of layering from high to low by first processing edge strip outside, obtaining edge strip thickness in processing inner side.When edge strip thickness thickness≤2mm and height > 40mm, edge strip processes outside and causes edge strip rigidity to reduce, and during processing inner side, edge strip trembles, and is attended by cutter vibration simultaneously, causes edge strip surface roughness variation.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of and is applicable to outside edge strip flutedly, and edge strip termination opens wide, and edge strip thickness≤2mm, the numerical-control processing method of the part of height > 40mm.
The technical scheme that the invention adopts is: the numerical-control processing method of the thin-walled parts of opening wide with side groove termination is as follows:
1) processing of groove outside edge strip: using woollen baseplane and side plane as positioning datum, the edge strip profile of the fluted side of first roughing, then change woollen modes of emplacement, using original side plane as baseplane, baseplane is as side plane, still usining these two planes processes groove as positioning datum, then woollen is returned to former modes of emplacement;
2) processing of opening wide end of edge strip: during processing parts profile, first process the part except edge strip is opened wide termination, keep edge strip to open wide being connected of end and border woollen, under this state, complete the processing of edge strip thickness, cut off edge strip again and open wide end and being connected of woollen, formation edge strip is opened wide end profile;
3) processing of edge strip thickness: adopt and alternately to process that edge strip is outer, the method for inner side, after completing one deck processing in edge strip outside then complete one deck processing of edge strip inner side, and so forth, the final edge strip needing that obtains.
The beneficial effect of the invention is: 1. adopt the processing method of groove outside edge strip of the present invention, groove, without using the working position apparatuses such as square chest, has been saved the required working time of workman's lifting station utensil outside processing edge strip, has improved part working (machining) efficiency.In addition, the positioning datum that groove adopts outside the method processing edge strip is consistent with the positioning datum that other positions of processing adopt, and has eliminated positioning datum and has converted the position error of bringing, and groove location is more accurate outside the edge strip processing.2. adopt edge strip of the present invention to open wide the processing method of end, when processing parts edge strip thickness, kept edge strip to open wide end and being connected of woollen, when proceeding to edge strip, cutting opens wide when end, the vibration that edge strip produces conducts to border woollen by connection, thereby make to tremble remitted its fury, edge strip steadiness improves, and guarantees that edge strip opens wide end thickness and meet product design requirement, obtains qualified products.3. adopt the processing method of edge strip thickness of the present invention, in process, kept to greatest extent the rigidity of high thin edge strip, reduced the vibration of edge strip work in-process and the impact that cutter vibration causes edge strip, guaranteed that edge strip obtains good surface roughness.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the invention processing edge strip.
The specific embodiment
the numerical-control processing method of the thin-walled parts that embodiment band side groove termination opens wide
Method is as follows: as shown in Figure 1, and 1-woollen in figure; 2-part edge strip is opened wide end; 3-part edge strip is opened wide the connection of end woollen; The high thin edge strip of 4-; Groove outside 5-edge strip.
1) processing of groove outside edge strip: using woollen baseplane and side plane as positioning datum, the edge strip profile of the fluted side of first roughing, then change woollen modes of emplacement, using original side plane as baseplane, baseplane is as side plane, still usining these two planes processes groove as positioning datum, then woollen is returned to former modes of emplacement, more down completes the processing at other positions.
2) processing of opening wide end of edge strip: during processing parts profile, the first part of processing except edge strip is opened wide termination, maintenance edge strip is opened wide and is held and being connected of border woollen, and completes the processing of edge strip thickness under this state, cut off edge strip again and open wide end and being connected of woollen, formation edge strip is opened wide end profile.
3) processing of edge strip thickness: because processing edge strip both sides all adopt the mode of layering from high to low processing, thereby be adjusted into and alternately process that edge strip is outer, the method for inner side, after completing one deck processing in edge strip outside then complete one deck processing of edge strip inner side, and so forth, the final edge strip thickness needing that obtains.
