Description
Technical field
The invention belongs to aircraft riveted joint mounting technology, relate to a kind of plush copper self-plugging rivet and decompose instrument and decomposition method thereof.
Background technology
Owing to used a large amount of plush copper self-plugging rivets in the aircaft configuration riveted joint, in process of production,, need decompose a large amount of plush copper self-plugging rivets sometimes owing to reasons such as riveted joint fault, structure repairs.Owing to have corresponding instrument, workman can only use drill bit that self-plugging rivet push rod locking trepan is not fallen earlier, use punching pin that push rod is washed out then after, re-use drill bit and decompose ailhead and will follow closely bar with the tack punching pin and wash out, like this could be with a self-plugging rivet decomposition.
Yet because the nail bar material of self-plugging rivet is very hard; Take down self-plugging rivet binding ring relative difficult and accomplish, the operation of decomposing manufactured head relatively easily produces fault, for veteran worker since experience and gimmick accurately then to decompose quality better; But then be difficult for grasping for the new worker; And when carrying out a large amount of disintegration, efficient is low, is easy to generate quality accident.
Summary of the invention
The objective of the invention is: propose a kind ofly in the decomposable process of self-plugging rivet, decomposition rate is fast, quality is high and can satisfy the plush copper self-plugging rivet decomposer of different-diameter plush copper self-plugging rivet requirement.
In addition, the present invention provides a kind of decomposition method of self-plugging rivet.
Technical scheme of the present invention is: a kind of plush copper self-plugging rivet decomposer; It comprises axle, lock-screw, limited block, inner sleeve, limit casing, outer spring, fine setting sleeve pipe, hollow boring bit, self-lubricating pad, limiting gasket, inner spring, and wherein, said axle is arranged in the inner sleeve; It is exposed at the outer end of inner sleeve and is provided with limited block through lock-screw; And outer spring twines on the axle be arranged in the inner sleeve, and axle is provided with self-lubricating pad and limiting gasket near inner sleeve port place, and said inner sleeve is arranged in the limit casing; Has toroidal cavity between the two; Be provided with inner spring in this toroidal cavity, and inner sleeve inside has the step surface that is used to limit limiting gasket, said limit casing is arranged in the fine setting sleeve pipe of hollow; Hollow boring bit is arranged on the bottom of axle and is positioned at the fine setting sleeve pipe, and its hollow size is not more than the diameter of rivet bar.
Said fine setting sleeve bottom is provided with removable fast resleeve.
Said hollow boring bit is basic consistent with the rivet bar diameter.
The lower surface of said limit casing is meshed through sawtooth with the upper surface of fine setting sleeve pipe and is connected.
Said limiting gasket is a steel washer.
A kind of self-plugging rivet decomposition method, it comprises the steps:
Step 1:, select to change corresponding quick change drill bushing according to the diameter of different manufactured heads;
Step 2: the position of debugging self-plugging rivet plush copper cutting bit
Adjustment process is following: upwards pull out limit casing, make limit casing break away from fine setting sleeve pipe, rotary fine adjustment sleeve pipe; Hollow bit location reaches and meets the position of the manufactured head decomposition not being destroyed structure when guaranteeing under axially, to promote final position; Unclamp limit casing then, under the effect of outer spring, the tooth on the limit casing cooperates with the tooth of restriction fine setting sleeve pipe; Thereby the position of restriction fine setting sleeve pipe makes the locked fine setting sleeve pipe of limit casing;
Step 3: the axle installation is clamped on the air drill;
Step 4: the quick change drill bushing is positioned on the manufactured head;
Step 5: self-plugging rivet plush copper cutting bit bores the self-plugging rivet head
Start air drill downwards by axle; Axle drives limited block and self-lubricating packing ring, limiting gasket and self-plugging rivet plush copper cutting bit move downward; Self-plugging rivet plush copper cutting bit bores the self-plugging rivet head; When step surface in limiting gasket and the inner sleeve contact spacing after, self-plugging rivet plush copper cutting bit is just taken off self-plugging rivet head branch and is not destroyed structure;
Step 6: go out the self-plugging rivet core bar;
Step 7: go out self-plugging rivet.
Advantage of the present invention is: plush copper self-plugging rivet decomposer of the present invention can be controlled the degree of depth that hollow boring bit bores accurately, thereby can make things convenient for the dismounting that accurately realizes rivet through the qualification of step surface in the inner sleeve; And through changing fast resleeve; The plush copper self-plugging rivet that can satisfy the variety classes diameter decomposes requirement, and is easy to use, and adjustment is quick; Significantly improve decomposition efficiency and decompose quality; Be fit to a large amount of disintegration, can satisfy the requirement of correlation technique file, have bigger practical value.
