Abstract
The invention belongs to aircraft repair technology, relating to a kind of to the repair method to immersing oneself in draw nest a kind of on aircraft.The present invention adopts and makes packing ring and fill and draw the mode of nest, and creationary use countersunk rivet makes packing ring, and institute uses countersunk rivet for typical standard part in aircraft riveted joint, and draw materials conveniently, making simply, is effectively shortened repair time, saved valuable delivery cycle.By this cover repair scheme, reaching to fill up and immerse oneself in draw the object of nest, after making to increase the similar structures such as sticking patch, formerly immerse oneself in draw a nest place and there is no gap, optimize structure, avoiding to immersing oneself in draw that nest is repaired improper and stress that is that cause is concentrated.
Description
Technical field
The invention belongs to aircraft repair technology, relating to a kind of to the repair method to immersing oneself in draw nest a kind of on aircraft.
Background technology
In the riveting process of aircraft, or because strength reasons needs to strengthen due to maloperation or when repairing, needing increases sticking patch at the similar structures such as exterior skin, in the process of repairing, find that original design draws nest, after increasing sticking patch or other reinforcement parts, immerse oneself in draw a nest and still exist.
At present, the process of nest is drawn for immersing oneself in, mostly be increase rivet diameter to immerse oneself in draw a nest to eating up completely, or reservation is immersed oneself in draw a nest and is not processed, the former is because the reason rivet of back gauge usually cannot increase to the diameter of meet requirements, and the latter retain immerse oneself in draw a nest easily cause stress to concentrate, easily crack in the place that fatigue load is larger especially.
Summary of the invention
The present invention have devised a set of repair method for immersing oneself in draw nest, object is the processing method in order to improve for immersing oneself in draw nest, rivet diameter used or immerse oneself in draw nest and the stress that causes is concentrated because retaining when avoiding increasing repairing because immersing oneself in draw the existence of nest, to improve the existing situation of immersing oneself in draw nest repairing technology and cannot process or deal with improperly in aircraft riveting process.
Technical solution of the present invention is,
Step one: make packing ring with the to be repaired stroke of identical solid countersunk rivet of nest diameter,
The method for making of packing ring is,
1., after selected solid countersunk rivet being coated with EA9392 glue, be riveted on one block of aluminium sheet,
At room temperature solidification sky or 80 ° of C ± 5 ° C solidify 1 hour,
2., after solidification, the rivet rod of solid countersunk rivet and rivet pier nose 4 are bored;
3. the remainder of solid countersunk rivet is taken out from aluminium sheet, be to repair and draw packing ring needed for nest;
Step 2: by packing ring 2 made in step one, be bonded to be repaired immersing oneself in after dipping in EA9392 glue and draw nest place, be cured, cured at room temperature 7 days or 80 ° of C ± 5 ° C solidify 1 hour;
Step 3: place sticking patch at the upper surface of repaired being solidified with packing ring, again rivet.
If position to be repaired is stressed little, on repaired that is solidified with packing ring, sticking patch can not placed, directly again rivets.
The advantage that the present invention has and beneficial effect, the present invention adopts and makes the mode that packing ring fills stroke nest, and creationary use countersunk rivet makes packing ring, use countersunk rivet for typical standard part in aircraft riveted joint, draw materials conveniently, make simple, effective shortening repair time, saves valuable delivery cycle.
By this cover repair scheme, reaching to fill up and immerse oneself in draw the object of nest, after making to increase the similar structures such as sticking patch, formerly immerse oneself in draw a nest place and there is no gap, optimize structure, avoiding to immersing oneself in draw that nest is repaired improper and stress that is that cause is concentrated.

Detailed description of the invention
Step one: make packing ring 2 with the to be repaired stroke of identical solid countersunk rivet 1 of nest diameter,
The method for making of packing ring 2 is,
1., after selected solid countersunk rivet 1 being coated with EA9392 glue 8, be riveted on one block of aluminium sheet 6,
At room temperature solidification 7 days or 80 ° of C ± 5 ° C solidify 1 hour,
2., after solidification, the rivet rod 3 of solid countersunk rivet 1 and rivet pier nose 4 are bored;
3. the remainder of solid countersunk rivet 1 is taken out from aluminium sheet 6, be to repair and draw packing ring 2 needed for nest;
Step 2: by packing ring 2 made in step one, be bonded to be repaired immersing oneself in after dipping in EA9392 glue 8 and draw nest place, be cured, cured at room temperature 7 days or 80 ° of C ± 5 ° C solidify 1 hour;
Step 3: place sticking patch 5 at the upper surface of repaired being solidified with packing ring 2, again rivet.
If position to be repaired is stressed little, on repaired that is solidified with packing ring 2, sticking patch can not placed
5, directly again rivet.
Embodiment
1. helicopter horizontal tail is drawn nest place in the middle part of covering due to strength reasons, needing to increase sticking patch, horizontal tail draws nest diameter 4mm, is fill out after the solid countersunk rivet of 4mm makes packing ring painting EA9392 to draw the solidification of nest place with diameter, again rivet after increasing sticking patch, pay smoothly after repairing.
2. during the assembling of helicopter vertical fin side skin, due to workman's maloperation, not needing a stroke nest place to draw nest diameter 3.2mm, due to not quite stressed, be, after 3.2mm solid countersunk rivet making packing ring fills up stroke nest solidification, again rivet new rivet with diameter.
