Description

Technical Field

[0001] The utility model relates to the technical field of aviation tools, and specifically relates to a glue remover for removing the sealant of a Hi-Lok nut packet. Background Art

[0002] With the development of modern aviation technology, a large number of new materials are used in aircraft structures. The most typical representative is the widespread application of composite materials, which has led to a revolution in aircraft assembly processes. A large number of new fasteners are used in aircraft manufacturing, and the most representative one is the extensive use of Hi-Lok bolts. In parts with high sealing requirements, after fastening with Hi-Lok bolts, a sealing treatment will also be carried out on one side of the nut, that is, a layer of sealant is sealed on one side of the Hi-Lok nut to wrap the nut inside to achieve the purpose of sealing.

[0003] During the processes of assembly, repair, and troubleshooting, when some Hi-Lok bolts need to be removed due to quality problems, it is necessary to first remove the sealant on the nut surface. At present, there is no special tool in the repair workshop for removing the sealant on the nut surface, and the removal method is mainly manual operation. The operator holds a scraper or a flat-tip screwdriver and scrapes along the circumference of the Hi-Lok nut bit by bit on the part surface. In actual operation, the above-mentioned existing technology has the following deficiencies: Since the sealant is firmly bonded to the Hi-Lok nut and the part, it takes a lot of man-hours to remove it, and the removal is not clean, and it is also easy to damage the part surface, especially for composite materials. This kind of damage may directly lead to the scrapping of the part. Summary of the Invention

[0004] In order to overcome the deficiencies of the existing technology, the utility model provides a glue remover for removing the sealant of a Hi-Lok nut, which can be applicable to removing the sealant heads of Hi-Lok nuts of different sizes.

[0005] The technical solution of the utility model is as follows:

[0006] A glue remover for removing the sealant of a Hi-Lok nut includes a clamping mechanism and a glue removing mechanism; the glue removing mechanism is movably installed at the front end of the clamping mechanism;

[0007] The clamping mechanism includes symmetrically arranged first handle, second handle, compression spring, and spring positioning pin; the first handle and the second handle cross and are hinged to form a pliers structure, which is used to form a clamping part at the front end under the action of an external force, so as to provide a cutting force for the glue removing mechanism; the compression spring is fixedly arranged between the hand-held parts of the first handle and the second handle through the spring positioning pin, and is used to provide a reset force after cutting to make the sealant separate from the glue removing mechanism;

[0008] The degumming mechanism includes symmetrically arranged first cutting edges, second cutting edges, first translation limiting rods, second translation limiting rods, cutting edge mounting screws and several pins; the first cutting edge and the second cutting edge are respectively fixedly mounted at the front ends of the first translation limiting rod and the second translation limiting rod through the cutting edge mounting screws, and are used for cutting the sealant on the surface of the part; the first translation limiting rod and the second translation limiting rod are respectively movably mounted at the front ends of the first handle and the second handle through pins, ensuring that during the process of forming a clamping part at the front ends of the first handle and the second handle, the first translation limiting rod and the second translation limiting rod can only perform lateral translation movements, thereby ensuring that a cutting force along the surface direction of the part is provided to the degumming mechanism.

[0009] Further, in the clamping mechanism, the first handle and the second handle have the same structure; the front end of the handle is provided with a first pin hole, a second pin hole and a third pin hole; the middle of the handheld part at the rear end of the handle is provided with a fourth pin hole; the first handle and the second handle are cross-hinged and mounted together through the second pin hole at the front end of the handle to form a pliers body structure.

[0010] Further, in the clamping mechanism, spring positioning pins are fixedly arranged in the fourth pin holes in the middle of the handheld parts at the rear ends of the first handle and the second handle, and the two ends of the compression spring are respectively fixedly connected to the spring positioning pins of the first handle and the second handle.

[0011] Further, in the degumming mechanism, the first translation limiting rod and the second translation limiting rod have the same structure; the front end of the first translation limiting rod is provided with a fifth pin hole, the rear end is provided with a waist-shaped groove, and a cutting edge mounting screw hole is provided on the front end face; the first translation limiting rod is hinged to the first pin hole of the first handle through the fifth pin hole; the first translation limiting rod is hinged to the third pin hole at the front end of the first handle through the waist-shaped groove; the second translation limiting rod is symmetrically arranged with the first translation limiting rod, and the second translation limiting rod is mounted at the front end of the second handle, ensuring that during the process of forming a clamping part at the front ends of the first handle and the second handle, the first translation limiting rod and the second translation limiting rod can only perform lateral translation movements.

[0012] Further, in the degumming mechanism, the first cutting edge and the second cutting edge have the same structure; the front end of the first cutting edge is a horizontal cutting edge, and an installation round hole is provided at the rear end; the cutting edge mounting screw passes through the installation round hole at the rear end of the first cutting edge and is screwed into the cutting edge mounting screw hole on the front end face of the first translation limiting rod to fasten and mount the first cutting edge at the front end of the first translation limiting rod; the second cutting edge is symmetrically arranged with the first cutting edge, and the second cutting edge is mounted at the front end of the second translation limiting rod. After installation, it is ensured that the front cutting edge of the cutting edge is perpendicular to the direction of the translation limiting rod.

[0013] Further, each component of the clamping mechanism and the degumming mechanism is made of 45 steel.

[0014] When using the above degumming device to remove the seal on the Hi-Lok nut, the operator holds the handheld part of the handle, presses the cutting edge at the front end of the degumming device against the surface of the part, and positions the seal between the two cutting edges. Then, apply force to the handle. When the front end of the clamping mechanism clamps, the translation limiting rod translates horizontally close along the surface of the part, thereby driving the cutting edge to also translate horizontally close along the surface of the part, gradually cutting into the bottom of the seal. After clamping the seal, do not release the hand, keep the degumming device perpendicular to the surface of the part and rotate more than half a circle, and finally pull upward perpendicular to the surface of the part to remove the seal.

By setting the first handle and the second handle to clamp, it can adapt to Hi-Lok nut seals of different sizes; by setting the translation limiting rod to cooperate with the cutting edge, it can remove Hi-Lok nut seals of different sizes with high quality; because holding the first handle and the second handle to clamp is fast and stable, compared with the existing manual scraping method, the present utility model can greatly improve the removal efficiency of the Hi-Lok nut seal, and the removal is clean without damaging the surface of the part.
