Abstract
The invention relates to an interference fit connection, in particular to an adjustable interference fit connecting piece. The connecting piece is composed of a conical bolt 1, a shear sleeve 2, a gasket 3, a nut 4 and a split pin 5. The mode of combining a hexagon head and an external thread cylinder head is adopted at one end of the conical bolt, and the mode of standard external thread is adopted at the other end of the conical bolt. The shear sleeve is of a hollow tubular structure with an axial gap and a conical internal diameter section. An unthreaded rod of the conical bolt is of the structure with a conical external diameter section, and is mounted in the shear sleeve. After the connecting piece is installed, different interference fit sizes can be obtained by adjusting the tightening torque of the bolt. By the aid of the adjustable interference fit connecting piece, the interference fit size of the adjustable interference fit portion of a plane can be adjusted conveniently, dismounting and mounting are easy, dismounting and mounting time of the connecting piece on the plane is effectively shortened, maintenance time is shortened, damage to lugs of the plane body is avoided, and safety, simpleness and swiftness are achieved.
Description
Technical field
The present invention relates to a kind of adjustable Interference Joints of aircaft configuration.
Background technique
Interference fit is one exemplary Connecting format, and airplane design has a wide range of applications, and particularly connects at wing body, undercarriage and body connection part, needs often to change, checks, the application of important connection part that Gao Cheng cuts is more general.Traditional interference fit structure comprises bolt, nut, pad, cotter pin.Need be installed by force by bolt by instrument during installation, easily cause Assembly of the parts to damage, interference fit size is fixed, and cannot carry out fit dimension adjustment according to real work situation.
Summary of the invention
The object of the invention is to solve conventional interference cooperating structure assembling easily damage, and the problem of amount of interference cannot be regulated, a kind of adjustable Interference Joints of aircaft configuration is provided.
Technical solution of the present invention is, a kind of adjustable Interference Joints, is characterized in that, comprises taper bolt 1, shears sleeve 2, packing ring 3, nut 4 and cotter pin 5; Taper bolt 1 polished rod adopts external diameter cross section to be the structure of taper, one end is the form of hexagon head and the combination of first two termination of outside thread cylinder, the other end adopts standard external, shearing sleeve 2 is hollow tubular structure, adopt the tapered bore section form of band axial slits, coordinate with taper bolt 1, sheared the axial slits size of sleeve 2 by nut extruding adjustable, and then the external diameter of sleeve 2 is sheared in adjustment, play the effect of adjustment amount of interference.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention, wherein, and taper bolt 1, shearing sleeve 2, packing ring 3, nut 4 and cotter pin 5.
Fig. 2 is the schematic diagram of taper bolt of the present invention, wherein, and hexagon head 6, socket cap 7, tapered cross-section 8, outside thread 9 and breaking pin hole 10.
Fig. 3 is the schematic diagram that the present invention shears sleeve; Wherein, small gaps 11, convex shoulder 12, tapered cross-section 13;
Fig. 4 is scheme of installation of the present invention, wherein, and the auricle 14 of band lining, the auricle 15 of band bearing.
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
This invention is made up of taper bolt 1, shearing sleeve 2, packing ring 3, nut 4 and cotter pin 5.As shown in Figure 1.
Taper bolt 1 polished rod partial design is tapered cross-section 8, and taper bolt 1 one end is designed with the bolt end form of hexagon head 6 and socket cap 7 combination, and socket cap 7 standard external processed, the other end is designed with standard external 9 and breaking pin hole 10, as shown in Figure 2.
Shear sleeve 2 and be designed with convex shoulder 12, internal surface is designed to tapered cross-section 13, and is shaped with small gaps 11, for regulating interference fit amount, as shown in Figure 3.
During installation, first will shear sleeve 2 successively through the auricle 14 of band lining and the auricle 15 of band bearing, with the hex head bolt head 6 of interior Hexagonal jacket clamping taper bolt 1, taper bolt 1 is installed to and shears in sleeve 2, then assemble pad 3, nut 4 and cotter pin 5, installation process is simple.
When needing larger interference fit size, increased by nut 4 screw-down torque, taper bolt 1 moves vertically, and the gap 11 of shearing sleeve 2 is increased, and shears sleeve 2 external diameter and expands, hold out against auricle 14,15, can reach and increase amount of interference requirement; When needing less interference fit size, reduced by nut 4 screw-down torque, taper bolt 1 moves vertically, and shearing sleeve 2 gap 11 is reduced, and shears sleeve 2 external diameter and shrinks, can reach and reduce amount of interference requirement.
When dismantling adjustable interference link, first by cotter pin 5, nut 4, after pad 3 is dismantled, be with externally threaded cylindrical bolt termination 7 to tighten with containing female installing sleeve and taper bolt 1, gently draw installing sleeve, after conical bolt 1 is dismantled, taken off by shearing sleeve 2, unloading process is convenient and swift, and is down to minimum to the damage of body auricle.
