The airplane float drilling tool disclosed by the utility model has the advantages of very conveniently drilling holes by an airplane float joint drilling method, avoiding errors during pre-assembly of finished-product floats, ensuring the drilling quality, meeting the interchangeability requirements of an emergent float, improving the yields of products and effectively shortening the riveting assembly period.
Description
Technical field
The utility model belongs to aircraft riveted joint mounting technology, relates to a kind of aerofloat drilling tool.
Background technology
Connecting bolt hole on the aircraft between emergent floating drum joint and the finished product floating drum traditionally; Normally structurally with the prepackage of finished product floating drum; Adjust the gap between periphery and the frame beam, add on the joint to machine according to the hole drill system on the finished product then, this method is called according to joining method.The emergent floating drum joint that uses traditional photograph to join after the method riveted joint is assembled can only be installed the corresponding finished product that shines after joining, and can not satisfy the interchangeability requirement of product, has reduced the riveted joint assembly quality of product.Limited by finished product floating drum procurement cycle, do not have the finished product floating drum just can't carry out the boring of structural joint,, influenced aircraft and paid according to plan so the riveted joint fittage can't be accomplished according to the production schedule.
The utility model content
The purpose of the utility model is: propose a kind ofly can avoid biased poor according to joining the hole that the legal system hole produces, guarantee the interchangeability of emergent floating drum, improve the aerofloat drilling tool of product percent of pass.
The technical scheme of the utility model is: a kind of floating drum joint drilling tool; It comprises vertical square steel, bolt, bushing plate, gusset, connecting plate, drill bushing, bearing diagonal plate, base, horizontal square steel; Wherein, said vertical square steel lower end links together through connecting plate with horizontal square steel, and gusset one end is connected with the bearing diagonal plate; One end links to each other with horizontal square steel; Said bushing plate is connected on the gusset through bolt, and offers some circular holes that are used to install drill bushing on each bushing plate, and said base is connected on the horizontal square steel through bolt.
The circular hole number that is used to install drill bushing on each bushing plate is 6.
Position, circular hole hole manufacturing tolerance on bushing plate and the base is not more than ± 0.2mm.
The utility model has the advantages that: the utility model uses the boring of aerofloat joint method for drilling very convenient; Avoided the deviation that when prepackage finished product floating drum, occurs; Guaranteed drilling quality; Satisfy the interchangeability requirement of emergent floating drum, improved product percent of pass, shortened riveted joint assembly period effectively.

Wherein, vertical square steel 1, bolt 2, bushing plate 3, gusset 4, connecting plate 5, drill bushing 6, bearing diagonal plate 7, base 8, horizontal square steel 9.
The specific embodiment
Explain further details in the face of the utility model down.
Please consult Fig. 1 and Fig. 2 simultaneously, wherein, Fig. 1 is the front view of the utility model aerofloat drilling tool, and Fig. 2 is the structural representation of the utility model aerofloat drilling tool.The utility model floating drum joint drilling tool comprises vertical square steel 1, bolt 2, bushing plate 3, gusset 4, connecting plate 5, drill bushing 6, bearing diagonal plate 7, base 8, horizontal square steel 9.
Wherein, the horizontal square steel 9 in said vertical square steel (two) lower end and lower end () links together through connecting plate 5 (two).Said gusset 4 (two a) end is connected with bearing diagonal plate 7 (two), and an end links to each other with horizontal square steel 9.Be connected on the gusset 4 through bolt 2 on the said bushing plate 3, and offer 6 circular holes that are used to install drill bushing on each bushing plate 3.Said base is connected on the horizontal square steel 9 through bolt.
During actual installation, earlier the horizontal square steel 9 in vertical square steel 1 (two) lower end and lower end () is welded together through connecting plate 5 (two); Gusset 4 (two) and bearing diagonal plate 7 (two) are welded together.Weld vertical square steel 1 upper end (two), the horizontal square steel 2 in upper end (), connecting plate 5 (two) then.Then weld upper end laterally square steel 9 () and gusset 4 (two).Use bolt 2 (four) to connect bushing plate 3 (two), gusset 4 (two) again; Connect the horizontal square steel 9 in lower end (), base 8 (two) with bolt 2 (four).At last drill bushing 6 is installed in the circular hole of bushing plate 3.The circular hole that being used on the bushing plate 3 (two) installed drill bushing 6 is 12, and the circular hole number on the base 8 is 8.
After above-mentioned installing; Design the three-dimensional digital-to-analogue of drilling tool simultaneously according to product digital-to-analogue coordinate; In the three-dimensional digital-to-analogue of frock these the four groups of holes integral body on the frock are considered; Frock requires these four groups of Kong Kongwei manufacturing tolerances at ± 0.2mm when making, because the boring degree of accuracy of the manufacturing degree of accuracy in these holes decision floating drum joint drilling tool, so position, hole relative size manufacturing tolerance is strict; Must be to install four groups of holes, back while boring system to form, then drill bushing 6 is installed in the circular hole of bushing plate 3.
The method for using of floating drum joint drilling tool: (four) are positioned at floating drum joint drilling tool on the aircaft configuration through bolt 2, and (four) locate the lower end that compresses drilling tool with bolt 2.During location, drilling tool upper end; The hole back gauge size that at first provides according to product drawing; Wanting the centerline hole that draws on the structural shape of drilling,, clamping bushing plate 3 and structural shape with arc ten thousand power folder then the drawn centerline hole of circular hole centrally aligned of bushing plate on the drilling tool 3; After guaranteeing to fit between bushing plate 3 and the structural shape; In bushing plate 3, put into drill bushing 6, so just accomplished the location of floating drum joint drilling tool, the operator just can begin to carry out boring work---and utilize the hole of drill bushing 6 to bore the bolt hole on the system structural shape.Use any two adjacent groups drill jig on the frock during boring simultaneously, put on bolt after the boring, and then use other two groups of drill jigs boring.Floating drum joint drilling tool is easy to use, and the easy operating person grasps.
The utility model aerofloat drilling tool is according to the coordinate of four emergent floating drum joint three-dimensional mathematical model each side; Design and manufacture floating drum joint drilling tool, bore according to the drill jig on this drilling tool then that machine adds the connecting bolt hole of joint on the system structure.After this aerofloat drilling tool is processed use, traditional according to according to join the method method for drilling be improved significantly, use floating drum joint drilling tool, it is very convenient hole, has avoided the deviation that when pre-installing the finished product floating drum, occurs.Ensured that effectively riveting fittage pays according to the completion and the aircraft of the production schedule according to plan.Aerofloat joint method for drilling has not only effectively shortened aircraft and has riveted assembly period, and has guaranteed drilling quality, satisfies the interchangeability requirement of emergent floating drum, has improved product percent of pass.The installation proof, the qualification rate of product has improved more than 80%, thereby has considerable economic benefit.
