Description
Technical Field
The utility model relates to the field of aviation bushing disassembly and assembly, in particular to a bushing rapid disassembly tool.
Background
In the field of aviation, in order to improve local stress part strength and wear resistance, a lining with various functions is often pressed into a base body through a hole, and the lining needs to be detached and replaced along with long-time and high-frequency use. When the bushing is installed, the single part and the bushing are installed. The general method is to disassemble by applying the axial force of the bushing, the complicated hole disassembly is limited by the environment, the bushing is disassembled by adopting the general method, the risk of damaging the bushing base hole or scrapping the bushing exists, the time and the labor are wasted, and the disassembly cost is high. The positions of the holes of the bushing base body are different, the general method is relatively limited, and the disassembly and the assembly of the through holes are often limited, if the holes meet the limit of the installation space of the step holes, the blind holes or the bushing, the force cannot be applied and the disassembly can not be carried out.
Disclosure of Invention
The utility model aims at solving the problems in the background technology, and provides a bushing quick dismounting tool which can safely and laborsaving withdraw a bushing without being limited by a base hole of a base body and damaging the bushing and the base hole of the base body.
According to the technical scheme, the quick bushing dismounting tool comprises a nut, a cover plate and a pull rod; the pull rod comprises a screw rod part, a matching table part and a rod head part which are integrally formed and sequentially distributed; the nut is in threaded connection with the screw rod part; the cover plate is provided with a through hole for the screw rod part to pass through and an end face for the nut to abut.
Preferably, the mating land is a boss structure, and the mating land edge includes a circular arc edge distributed around the screw portion.
Preferably, the head of the rod is of a regular hexagonal boss structure.
Preferably, the cover plate is of a barrel-shaped structure, and the through hole is positioned at the barrel bottom of the cover plate.
Compared with the prior art, the utility model has the following beneficial technical effects:
the utility model can conveniently disassemble and assemble the bushing on the base body, and converts the axial force of the original bushing disassembly into torsion. The spanner stably applies a rotation moment to the pull rod, so that the pull rod is driven to axially move, the bushing is driven to axially displace, and the bushing is disassembled. The whole operation is not limited by the base holes of the base body and the base holes of the lining and the base body are not damaged.

Detailed Description
As shown in fig. 1 to 4, the quick bushing disassembling tool provided in this embodiment includes a nut 1, a cover plate 2 and a pull rod 4.
The pull rod 4 comprises a screw rod portion 41, a matching table portion 42 and a rod head portion 43 which are integrally formed and sequentially distributed, the matching table portion 42 is of a boss structure, the edge of the matching table portion 42 comprises an arc-shaped edge which is distributed around the screw rod portion 41, the rod head portion 43 is of a regular hexagon boss structure and can be clamped in by a wrench to rotate, and the rod head portion 43 can be designed into other types of structures which can be rotated by the wrench, such as a regular polygon boss structure, a regular octagon boss structure and the like, as long as two opposite planes which can be clamped in by the wrench are provided.
The nut 1 is screwed to the screw portion 41, and the nut 1 abuts against the cover plate 2.
The cover plate 2 is provided with a through hole 201 for the screw portion 41 to pass through and an end face for the nut 1 to abut, the cover plate 2 is of a barrel-shaped structure, the through hole 201 is positioned at the barrel bottom of the cover plate 2, the inner ring size of the cover plate 2 is larger than the outer diameter of the bushing 3, and the bushing 3 can enter the inner side of the cover plate 2 after being extruded, so that the bushing 3 can be detached more smoothly.
The embodiment can conveniently disassemble and assemble the bushing 3 on the base body 5, and converts the axial force originally disassembling the bushing 3 into torsion. The spanner stably applies a rotation moment to the pull rod 4, so that the pull rod 4 is driven to axially move, the bushing 3 is driven to axially displace, and the bushing 3 is dismounted.
In the case of the disassembly applied to the bush 3, since the bush 3 is installed at the base 5, the passage on the right side of the base 5 is narrow, and the passage on the left side of the base 5 is wide, the tie rod 4 cannot be inserted from the right side of the base 5, but should be inserted from the left side of the base 5, i.e., in the direction a, the tie rod 4 needs to be inserted through the bush 3 in an oblique direction when the tie rod 4 passes through the bush 3, and when the mating stage 42 is moved to the right side of the bush 3, the tie rod 4 is turned right, and then the mating stage 42 is abutted against the end face of the bush 3. The cover plate 2 is sleeved on the periphery of the screw portion 41, the nut 1 is screwed on the screw portion 41, the nut 1 presses the cover plate 2 on the base body 5, and the position of the nut 1 is fixed. When the bush 3 is removed, the wrench is caught at the head 43 and rotated so that the pull rod 4 is screwed to the left, and the fitting stage 42 of the pull rod 4 can push out the bush 3 from the inside of the base body 5. In the same way, the bushing 3 can be pressed into the base body 5 in the opposite direction when applied to the mounting of the bushing 3.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited thereto, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
