Description
Technical Field
The application relates to the technical field of aircraft manufacturing, in particular to a tool for injecting glue between interlayers through a through hole.
Background
In the field of aviation, aircraft fuel tanks are generally formed by joining multiple sandwich panels by fasteners. Sealants are generally applied between the interlayers to ensure the tightness of the wing fuel tank. After the sealant is cured, a part of air bubbles still exist in the sealant. After the airplane is delivered to an outfield and passes through a complex environment and a special flight task for a period of time, the sealant package corner filling of the area of the oil tank part fails. Especially, some (small) clearance fit hole diameters can form oil leakage passages of 'the inside of the oil tank, the package, the filling angle, the hole wall, the interlayer and the outside of the oil tank'. Resulting in a tank area spill accident. The traditional fault elimination method is to perform encapsulation and corner filling again on the gluing area and the periphery, which has great workload and causes a great deal of waste of sealant. The method can only block an oil leakage path from the surface, cannot thoroughly repair the defect of the sealant in the interlayer, and cannot radically solve the oil leakage problem. In order to effectively and long-term solve the problem of fuel leakage, it is particularly urgent to design a tool for injecting glue into a multi-lamination structure through a through bolt hole.
Disclosure of Invention
In order to solve the problem, the application provides a through-hole to instrument of injecting glue between the intermediate layer. The tool has the characteristics of simple structure, low cost, sealant material saving, convenience in carrying and installation, suitability for construction of parts which are not opened and the like, and can fundamentally solve the problem of oil leakage of the interlayer of the oil tank region.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a through-hole to injecting glue instrument between intermediate layer, including the injecting glue head, the injecting glue pipe, the adapter, the injecting glue bucket, compression stick and pressure equipment, injecting glue bucket upper portion with through adapter and injecting glue union coupling, the lower part is connected with the compression stick, the compression stick is connected on pressure equipment's confession pressure mouth, the injecting glue head is the cavity rod-like structure of polished rod in the middle of the two screw threads, and the middle part is equipped with the injecting glue hole, the first one end of injecting glue is connected with the injecting glue union coupling, the other end passes through the sealing member shutoff, the injecting glue head passes the intermediate layer region through the through-hole during use, the intermediate layer both sides are compressed tightly sealed with compressing tightly the.
The beneficial effect of this application: the method is suitable for troubleshooting of the defects of the sealant in the structural interlayer after the bolt in the airplane oil tank area is subjected to wet installation. The device provides a feasible and efficient tool for repairing the defects of the sealant in the bolt hole and the interlayer of the narrow space part in the aircraft fuel tank structure, has the characteristics of small size, simple structure, low cost, simplicity and convenience in use and the like, and can effectively avoid the damage to the surface of the aircraft structure in the glue injection process.

Detailed Description
As shown in fig. 1 and fig. 2, a through-hole to injecting glue instrument between intermediate layer, including the injecting glue head, the injecting glue pipe, the adapter, the injecting glue bucket, the compression stick, compression equipment, injecting glue bucket upper portion with through adapter and injecting glue union coupling, the lower part is connected with the compression stick, the compression stick is connected on the pressure supply mouth of compression equipment, the injecting glue head is the hollow rod-shaped structure of polished rod in the middle of the two screw threads, and the middle part is equipped with the injecting glue hole, the first one end of injecting glue is connected with the injecting glue union coupling, the other end passes through the sealing member shutoff, the injecting glue head passes the intermediate layer region through the through-hole during use, the intermediate layer both sides. The sealing element is a screw, and a rubber pad is arranged between the compression nut and the interlayer.
The tool is simple in structure, the adapter can rotate 360 degrees, and the pressurizing equipment is ensured not to interfere with surrounding structures; rubber pads on two sides of the interlayer can ensure that the matrix around the aperture is not damaged when the compression nuts on two sides are clamped; the diameter of the glue injection head is slightly smaller than the aperture of the through hole, so that the installation of the glue injection head and the flowing of a sealant in the through hole are facilitated; the rear part of the glue injection head is sealed, so that the sealant remained in the glue injection head can be cleaned after the construction is finished.
The glue injector can be suitable for repairing the defects of the structural interlayer sealant after wet installation of standard components with various diameters, and is particularly suitable for repairing the defects of the interlayer sealant in a relatively narrow space area.
When the sealing device is used, the pressurizing device provides power, the compression rod moves along the inner wall of the glue injection barrel, the sealant is compressed and diffused from the glue injection hole in the middle of the glue injection head to the periphery of the lamination along the adapter and the glue injection pipe, the sealant is diffused to the lamination defect, the oil leakage passage is blocked, and the purpose of repairing the defect of the sealant is achieved.
