Tool takes out the honeycomb core between two layers of covering of part.The gas vent of 1.5mm diameter is bored near first hole simultaneously；
Step 4, injection filler: being sealed at first hole using adhesive tape, protection hole edge skin, is marked just hole with tool, is filled out
The casting of material is carried out with colloid-injecting gun.Filler is slowly injected into from first hole, is shown when filler is uniformly flowed out from gas vent tentatively
It fills, the injecting glue again after 15 minutes shows to fill completely when filler uniformly flows out again；
Step 5, solidification
One of with the following method solidification:
A) solidify 8 hours at 18 DEG C of environment temperature > plus 1 hour at 65 DEG C.
B) part can be moved after 7 days, 24 hours in the case where 18 DEG C of environment temperature >.
Step 6, after curing of the glue removes band glue, clears up extra glue, forms filling block insert.
Part is placed into numerical control tooling second and positions by step 7, using with the consistent positioning of first time technical lug
Auricle is accurately positioned；It is required that positioning process auricle quantity is no less than at 2；
Step 8 processes whole hole by numerical control program numerical control on first hole site, and aperture φ 5.5mm, alloy bit is by being lower than
The revolving speed of 4000r/min, the speed feed lower than 3m/s；
Step 9 cleans out fifth wheel in whole hole, wipes borings with clean cloth or uses wind；
Step 11 checks: the angle of whole axially bored line and skin-surface should be 90 ± 2 °, and panel surface bumps limit deviation ±
0.30mm。
The effect of invention
Metal decking sandwich of the present invention and composite honeycomb sandwich structures filling block insert drilling processing, such as visitor
Cabin floor drilling processing.Inventing this process can be used for filling block insert drilling processing, improves product quality, avoids hole
Size and position degree it is overproof.
Detailed description of the invention
Fig. 1: the machining sketch chart of helicopter filling block insert drilling；
1, technical lug location hole；
2, filling block insert；
3, hole need to be processed.
Specific embodiment
Method of the invention is: hole at the beginning of part is placed into numerical control tooling positioning → numerical control processing for the first time → stroke honeycomb →
It adjusts 17# filler → injection filler → solidification → extra glue cleaning → part to be placed into second of positioning → numerical control in numerical control tooling to add
Filling block insert drilling processing is completed in work end hole → cleaning → inspection.The method is suitable for the composite wood of any curved surface, plane
Flitch part filling block insert drilling processing.Fig. 1 is the machining sketch chart of helicopter filling block insert drilling, as shown in Figure 1,
It is provided with technical lug location hole 1 on part, filling block insert 2, hole 3 need to be processed.
Step 1 will position for the first time on part to numerical control tooling, and technical lug is accurately positioned；It is required that positioning process auricle
Quantity is no less than at 2；
Step 2, by numerical control program numerical control processing, just hole, aperture φ 3mm, alloy bit (are lower than 5000r/ by the slow-speed of revolution
Min), low feeding (being lower than 2m/s)；
The diameter in insert hole is expanded to insert diameter with stroke hole drill by guide hole of the hole of φ 3mm and uses " hook-type " by step 3
Tool takes out the honeycomb core between two layers of covering.Taken out honeycomb diameter answers the regulation of coincidence pattern.It nearby bores simultaneously
The gas vent of 1.5mm diameter；
Note: taken out honeycomb diameter answers the regulation of coincidence pattern.It is especially careful not push away, draw exterior skin (otherwise to will lead to
The layering of covering).Borings are wiped with clean cloth or with wind (wanting oil-free anhydrous).
Step 4 is provided to adjust 17# filler by technical papers, injects filler: being sealed at first hole using adhesive tape, protect hole edge
Edge covering marks just hole, the casting of filler with tool and is carried out with colloid-injecting gun.Colloid-injecting gun is SEMCO type pneumatic type, and having can
The packing element C250 and adhesive pouring nozzle of disassembly.Filler is slowly injected into from a hole (hole for injecting glue), equal from another hole (gas vent) to filler
Show tentatively to fill when uniform flow goes out, the injecting glue again after about 15 minutes shows to infuse completely when filler uniformly flows out again
It is full；
Note: colloid-injecting gun, adhesive pouring nozzle and various containers are cleaned with solvent immediately after use.
Step 5, solidification
One of with the following method solidification:
C) solidify 8 hours at 18 DEG C of environment temperature > plus 1 hour at 65 DEG C.
D) in the case where 18 DEG C of environment temperature > 7 days.Part can be moved after 24 hours.
Step 6, after curing of the glue removes band glue, clears up extra glue.It is removed if any extra glue knife or scraper plate, Zhi Houyong
Dip in the cloth cleaning of alcohol.Before solvent volatilization, surface is wiped with dry cloth is cleaned.
Step 7, part are placed into numerical control tooling second and position, using with the consistent chucking lug of first time technical lug
Piece is accurately positioned；It is required that positioning process auricle quantity is no less than at 2；
Step 8 presses numerical control program numerical control processing end hole, aperture φ 5.5mm, and alloy bit (is lower than by the slow-speed of revolution
4000r/min), low feeding (being lower than 3m/s)；
Step 9, cleaning are portalled interior fifth wheel, wipe borings with clean cloth or with wind (wanting oil-free anhydrous).
Step 10 checks: the angle of insert axially bored line and skin-surface should be 90 ± 2 °.The panel surface bumps limit is inclined
Difference ± 0.30mm.
