Abstract
The present invention relates to a kind of technique patch cutting methods of covering class part, belong to aircraft manufacturing processing technique field.The step of this method, is as follows: completing the processing of a skin part on numerically-controlled machine tool, continues to adsorb skin part with vacuum platform tooling after processing and push down contoured peripheries, skin technology patch includes skin shape periphery patch and part window frame patch；Scriber tool is installed on numerically-controlled machine tool, carries out scribing line processing along appearance profile or window frame profile；Part is removed from numerically-controlled machine tool, for the ease of manually performing removal covering defective material operation, is cut off the end of skin part with electric cutting tool；After scribing operation, the edge of skin part is due to stress concentration effect meeting season crack, the covering defective material for skin part of easily tearing manually.Covering class part of the present invention for absorption milling processing, the patch of quick cutting-off part peripheral shape, meanwhile, the External Shape remaining balance after removing patch is minimum, and uniformly.
Description
Technical field
The present invention relates to a kind of technique patch cutting methods of covering class part, belong to aircraft manufacturing processing technique field.
Background technique
Covering class part has certain radian, and material is mainly processed by numerical control device than relatively thin.It uses
Processing method is that part material is adsorbed on by force in Special vacuum platform tooling with vacuum pump, then in material peripheral pressing plate
It compresses, then carries out milling processing on numerically-controlled machine tool.Since part is adsorbed processing, so during milling part
Part bottom surface cannot be milled and be broken, otherwise will will cause gas leakage between part material and vacuum platform, and lose vacuum state, and make part
It tilts.In processing technology, when cutting off External Shape, it can retain company on External Shape periphery there are complete technique patch
Edge fit sink, and connects thickness about 0.5mm, finally by artificial removal, and removes technique patch.
The method of original technique patch cutting is by pneumatic tool, saw bow, chisel and drill bit round to be used to carry out technique
The excision of patch operates, these methods are time-consuming and laborious, can generate a large amount of dust, and processing efficiency is low, and technique patch is cut
After removing, it can be formed and be remained on part periphery.Later period, it is also necessary to carry out the work of a large amount of equating part peripheral shape, serious shadow
Ring the processing efficiency and processing quality of part.
Summary of the invention
The main object of the present invention is to propose a kind of new covering class part process patch cutting method, for absorption milling
The covering class part of processing, the patch of quick cutting-off part peripheral shape, meanwhile, more than the External Shape residual after removing patch
Amount is minimum, and uniformly.
The present invention to achieve the goals above, adopts the following technical scheme that
A kind of the step of technique patch cutting method of covering class part, this method, is as follows:
(A), the processing that a skin part is completed on numerically-controlled machine tool, continues to adsorb illiteracy with vacuum platform tooling after processing
Skin part simultaneously pushes down periphery, and skin technology patch includes skin shape periphery patch and part window frame patch；
(B), scriber tool is installed on numerically-controlled machine tool, carries out scribing line processing along appearance profile；
(C), part is removed from numerically-controlled machine tool, for the ease of manually performing removal covering defective material operation, uses electric cutting tool
The end of skin part is cut off；
(D), after scribing operation, the edge of skin part is easily torn manually due to stress concentration effect meeting season crack
The covering defective material of lower skin part.
Further, skin part has radian.
Further, skin part removes covering defective material after needing the position cut cutting, on skin part shape side
With skin part esconson.
Further, the end of skin part is cut off as triangle end with electric cutting tool.
What the present invention used goes the method abbreviation cutting-up method of technique patch, the principle mainly concentrated using stress.When thin
After wall covering class piece surface marks a score line, can generate using concentration phenomenon, material can since sectional dimension changes and
Cause the part of stress to increase, and fragile material is caused to be broken, produce meeting crack, quick, clean can go in this way
Except the remaining position of part.
Beneficial effects of the present invention:
1, processing benefit of the present invention is greatly improved；
2, practical operation of the present invention is more simpler than original, convenient；
3, after present invention excision, cutting method is carved in comparison and round blanking method residual is smaller, and the polishing process in later period is easier to handle；
4, dust will not be generated in process of the present invention, to personnel and less environmental pollution.

Specific embodiment
The present invention will be described in detail for connection with figures below:
A kind of the step of technique patch cutting method of covering class part, this method, is as follows:
(A), the processing that a skin part 1 is completed on numerically-controlled machine tool, continues to be adsorbed with vacuum platform tooling after processing
Skin part 1 simultaneously pushes down periphery, and skin technology patch includes skin shape periphery patch 3 and part window frame patch 4；
(B), scriber tool 6 is installed on numerically-controlled machine tool, carries out scribing line processing along appearance profile；
(C), part is removed from numerically-controlled machine tool, for the ease of manually performing removal covering defective material (2) operation, with electronic cutter
Tool cuts off the end of skin part 1；
(D), after scribing operation, the edge of skin part 1 is easily torn manually due to stress concentration effect meeting season crack
The covering defective material 2 of lower skin part 1.
Skin part 1 has radian.
Skin part 1 removes covering defective material 2 after needing the position cut cutting, in 1 shape side of skin part and covering
1 esconson of part.
The end of skin part 1 is cut off as triangle end 5 with electric cutting tool.
The method abbreviation cutting-up method for removing technique patch that this programme uses, the principle mainly concentrated using stress.When thin
After wall covering class piece surface marks a score line, can generate using concentration phenomenon, material can since sectional dimension changes and
Cause the part of stress to increase, and fragile material is caused to be broken, produce meeting crack, quick, clean can go in this way
Except the remaining position of part.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
