Description
Technical field
The present invention relates to aircraft parts processing technique field, more particularly to a kind of fin two ends rapid drilling fixture.
Background technology
Fin is the common part of aircraft, its on flight track and drop point accuracy influence it is huge.In practice
In, fin is connected by sail shaft with empennage frame, and is folded when realizing storage, the function of deploying during flight.However, fin hole
Diameter is small, only, length is 131, and required precision is high, and manufacturing batch is huge.Bored to save cost using radial drilling machine
A kind of hole, it is therefore desirable to fixture, is quick and precisely positioned during processing to it, convenient after processing to take out, while meeting batch production
It is required that, the time is saved, efficiency is improved.
At present, fin is often with boring grab basic condition：Fixture is by bottom plate, jig seat, pressing plate, Quick-change drill bush, interchangeable
Drill bushing is constituted.Pre- hole is bored by Quick-change drill bush, renewable bushing expands the process of pore-forming to process, and processing is completed by radial drilling machine.
The major defect of current this fixture is：
1st, processing is performed by pre- hole-work step of expansion pore-forming two is bored, and frequently changing drill bushing during production in enormous quantities wastes time and energy；
2nd, because the diameter in hole is small, length is big, and draw ratio reaches 26, and drilling length is long, and drill bit is rocked, after production pieces, under
Hold drill bushing by bit wear, cause fin hole hypomere tolerance easily overproof, it is impossible to meet required precision；It is unreliable that single-point is compressed,
Trembled when fin is processed after compression, cause overproof；
3rd, each clamping can only process a product, and processing efficiency is low, it is impossible to meet the requirement produced in enormous quantities.
The content of the invention
The purpose of the present invention is that a kind of fin two ends rapid drilling fixture of offer, to solve the above problems.
To achieve these goals, the technical solution adopted by the present invention is such：A kind of fin two ends rapid drilling fixture, bag
Model drilling body component, base and fastening screw are included, wherein, the model drilling body component is fixed by fastening screw with the base, also
Including being used for the spacing limited block of model drilling body component on the base；The model drilling body component includes upper plate, bottom
Plate and T-shaped riser, the T-shaped riser are located between upper plate and lower shoe, in addition to bushing plate, and the bushing plate is installed on T
Above and below shape riser at the preformed groove position of two T sections, the bushing plate is in spatial vertical relation with left pressing plate and right pressing plate, and
It is not directly connected, the bushing plate is embedded with drill bushing, the upper and lower ends of the left pressing plate and right pressing plate are respectively arranged with a fluting
Pad, more specifically, the fluting pad is arranged at left pressing plate and the upper and lower ends of right pressing plate are compressed near point.
It is used as preferred technical scheme：Also include chamfered edge pin, the chamfered edge pins position is on the side step surface of the base.
The operation principle of present clip is：
1st, 2 fins are positioned using T-shaped riser, bottom plate, then fin is clamped by the pressing plate of left and right 2 and 2 fluting pads, formed
Independent model drilling body component；
2nd, using chamfered edge pin, limited block on base fast rough, then realize with fastening screw model drilling body component and bottom plate
It is relatively fixed；
3rd, fin one end drilling is finished, 180 ° of upset model drilling bodies, other end fin hole processed；
4th, two ends drilling is finished, and unclamps fluting pad and pressing plate, takes out completion of processing fin, while changing 2 fins to be processed.
Compared with prior art, the advantage of the invention is that：
1st, the pre- hole work step of brill has been abandoned in design, it is to avoid frequently change drill bushing, drilling in place, is produced in enormous quantities during processing
When can effectively save the time, using the fixture of the present invention, production time per piece only needs 0.125h, and efficiency improves more than 2 times than before；
2nd, the pattern that elongated hole is only bored from one end is abandoned, two ends drilling is changed to, designs the model drilling body that can independently overturn, effectively prevent because boring
Head rocks the lower end drill bushing hole caused and worn and torn, lower stomidium dimension overproof, and 50 fin lower end drill bushings of processing are overproof report before improving
It is useless, using the fixture drill bushing life-span of the present invention up to more than 200；
3rd, long pressing plate is designed, it is 2 points of forces to change single-point force, fin plane stress is more balanced, mitigates fin and tremble phenomenon,
Simultaneously with fluting pad press tab side end face, in the case of without using instrument, make clamping more reliable and more stable；
4th, designing T riser, is positioned using T-shaped riser two sides, can once process two pieces fin, production efficiency has been obtained effectively
Improve；
5th, limited block, chamfered edge pin coarse positioning are designed in precalculated position, reuses wide arc gap alignment pin and be relatively fixed base and drill jig
Body, it is convenient and swift, positioning alignment time is greatlyd save, the efficiency of batch production is improved；During production in enormous quantities, the same number of processing
The fin of amount can save man-hour >=1700h/, remarkable in economical benefits.
