Background

The whole fuel tank on the airplane is usually riveted in a wet mode by adopting sealant, and when the riveting is completed and an airtight or oil-tight test is carried out, local oil leakage caused by the fact that individual rivets do not meet the sealing requirement is sometimes found. The method for solving the problem of oil leakage usually comprises the steps of removing the rivet at the oil leakage part, replacing the rivet viscose glue and riveting again. The whole oil tank is complex in structure, a plurality of parts are required to be detached when rivets are replaced, labor intensity is high, construction space is small, operation of workers is not easy, and new oil leakage points are easy to cause.

A pressure glue injector comprises a piston, a first screw, a shell, a first nut, a connecting plate, an adjusting washer, a steel wire, a rubber sucker, a pressure lever, a base, a second nut and a second screw; the piston penetrates through the interior of the shell and is connected with the shell through threads, and the contact part of the piston and the surface of the cavity of the shell is tightly attached; the rubber sucker is sleeved outside the shell and is connected with the shell in a steel wire winding and screwing mode; the upper part of the shell is provided with a threaded hole and is screwed with a screw I; the pressure lever penetrates through the lower part of the base and is connected with the base through threads; a threaded hole is formed in the side face of the lower part of the base, and a second screw is screwed in; the connecting plate is arranged on the upper parts of the shell and the base through a first nut and a second nut, the lower part of the connecting plate is supported on a convex shoulder on the outer surface of the base, and an adjusting washer is arranged between the connecting plate and the convex shoulder of the shell.

Furthermore, the outer surface of the shell of the pressure glue injector is provided with a convex shoulder, and the outer surface of the lower part of the convex shoulder of the shell is provided with at least one circle of grooves.

Furthermore, the piston and the upper part of the pressure rod of the pressure glue injector are hexagonal heads.

Furthermore, the contact part of the piston of the pressure glue injector and the surface of the cavity of the shell is made of rubber, and the piston and the cavity are in interference fit.

Furthermore, the upper part of a rubber sucker of the pressure glue injector is in a hollow cylindrical shell shape, and the lower part of the rubber sucker of the pressure glue injector is in a bell mouth shape.

The pressure glue injector has the advantages that the pressure glue injector can conveniently carry out pressure glue injection repair on the rivet at the oil leakage point outside the integral oil tank, greatly reduces operation difficulty, saves construction time and effectively improves product quality.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

A pressure glue injector comprises a piston 1, a first screw 2, a shell 3, a first nut 4, a connecting plate 5, an adjusting washer 6, a steel wire 7, a rubber sucker 8, a pressure lever 9, a base 10, a second nut 11 and a second screw 12; the piston 1 penetrates through the interior of the shell 3 and is connected with the shell 3 through threads, and the contact part of the piston 1 and the surface of the cavity of the shell 3 is tightly attached; the rubber sucker 8 is sleeved outside the shell 3 and is connected with the shell 3 in a winding and screwing mode through a steel wire 7; the upper part of the shell 3 is provided with a threaded hole and is screwed into the screw I2; the pressure lever 9 passes through the lower part of the base 10 and is connected with the base 10 through threads; a threaded hole is formed in the side face of the lower part of the base 10, and a second screw 12 is screwed in; the connecting plate 5 is arranged on the upper parts of the shell 3 and the base 10 through a first nut 4 and a second nut 11, the lower part of the connecting plate 5 is supported on a convex shoulder on the outer surface of the base 10, and an adjusting gasket 6 is arranged between the connecting plate 5 and the convex shoulder of the shell 3.

The outer surface of the shell 3 is provided with a convex shoulder, and the outer surface of the lower part of the convex shoulder of the shell 3 is provided with at least one circle of grooves.

The upper part of the rubber sucker 8 is in a hollow cylindrical shell shape, and the lower part of the rubber sucker is in a bell mouth shape.

Before use, the piston 1 is screwed downwards until the lower part of the piston is flush with the lower part of the shell 3, and the pressure rod 9 is screwed upwards as far as possible.

When the oil leakage position of the integral oil tank rivet needs to be repaired, the lower part of a base 10 of the pressure glue injector is aligned to the outer surface of a machine body at the rivet head position of a leakage point, the base 10 and the surface of the machine body are tightly adhered and sealed by using strong glue, in order to increase the sealing effect of the contact surface of the base 10 and the surface of the machine body, adhesive tapes are adhered around the outer part of a gap between the base 10 and the surface of the machine body as required, a rubber suction cup 8 of the pressure glue injector is adhered to the outer flat part of the airplane structure, a lower-pressure rubber suction cup 8 is adsorbed outside the airplane structure, and a piston 1 is screwed out upwards to remove empty devices in a cavity of a. Before the piston 1 is screwed out, the screw I2 on the shell 3 can be screwed out and taken down as required, the air displacement is increased, and the screw I2 is installed again after the required adsorption force is reached. The heights of the shell 3 and the base 10 are adjusted through the adjusting washers 6 with different thicknesses, and the base 10 is tightly attached to the surface of the machine body through the connecting plate 5, the first nut 4 and the second nut 11 in a pressing mode.

And (5) screwing off the second screw 12, and screwing down the second screw 12 again after injecting the sealant into the threaded hole of the base 10. The pressure injecting glue ware is twisted down with the depression bar 9 of pressure injecting glue ware, will seal the tight gap infiltration between rivet head and the structure of gluing, through twist, stewing, take off the pressure injecting glue ware after relapse a plurality of times to clean organism surface.

The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
