Description
Technical field
The present invention relates to a kind of structure, more particularly to a kind of mounting structure of control board bracket.
Background technology
Top control board bracket is to be used to install control board component on aircraft（The man-machine interfaces such as integrated switch, knob, display
Face equipment）Body structure, top control board bracket on it is existing for install control board component guide rail, also have and aircraft
The interface of structure connection, top controls board bracket that the load for controlling board component to be subject to is reliably delivered into aircaft configuration.Therefore,
Bracket should have enough strength and stiffness with the connection of aircaft configuration, while needing the Simple convenient for considering to install and safeguard.
Because the arc of aeroplane nose structure is controlled, aircraft structure has special relative tertiary location with tray chamber,
Consider connection reliability, typically using gusset plate and the connected mode of pull bar, Fig. 1 shows the Tiebar structure that bracket is installed, bracket
Gusset plate 21' on 2' is connected by pull bar 3' with the gusset plate 11' on plane beam structural member 1', by the use of multigroup attachment structure
Realize the fixation of bracket.Such structure type has the disadvantages that：
1. bracket and plane beam relative tertiary location are special, and gusset plate shape differs, and design difficulty is big, and processing and manufacturing difficulty is bigger,
Intensity Design expends the time；
2. Hard link is carried out by bolt between structural member, mount stress is easily accumulated in installation process；
3. the stress corrosion of structural member is easily caused in use；
4. design margin and processing and manufacturing deviation accumulation, cause bracket uneven with inside gadget faying face gap；
5. installation difficulty is big, and the difference of erection sequence can cause the difference of pull bar stress, it may be necessary to which frock carries out auxiliary positioning.
The content of the invention
It is an object of the invention to provide a kind of mounting structure and installation method of new control board bracket, by using
Aligning oscillating bearing replaces Hard link and replaces Drag link using thread, overcomes gusset plate and pull bar in above-mentioned background technology
The shortcoming existed when line carrier installation is entered.
To achieve these goals, the technical scheme is that：
A kind of mounting structure of control board bracket, including tie component, the tie component include a drag link body and are placed in described
The left and right drag link end body at drag link body two ends, the drag link body is to be threadedly coupled with the connected mode of the left and right drag link end body, institute
State threaded connection and be provided with latch assembly；The connected mode of the gusset plate on the left and right drag link end body and aircraft and bracket is bearing
Connection.
Further, the bearing connection is provided with aligning oscillating bearing, and the outer ring of the aligning oscillating bearing is by tight
Cooperation is installed on gusset plate, and the drag link end body is provided with the groove and installation being engaged with the inner ring of the aligning oscillating bearing
Hole, the inner ring end face of the mounting hole, the medial surface of the groove and the aligning oscillating bearing is connected by flanged bushing, spiral shell
Bolt is fixed by the endoporus of the flanged bushing and the inner ring hole of aligning oscillating bearing with packing ring and self-locking nut, is realized
The connection of drag link end body and gusset plate.
Further, the left and right of the drag link body is respectively arranged at two ends with left hand thread pore structure and right-handed thread pore structure,
The shaft end that the left and right drag link end body is connected with the drag link body is respectively equipped with left hand thread and right-handed thread；Left and right drag link end body
It is fixed on when on bracket gusset plate or plane beam structural member gusset plate, rotating tension bar body, realizes drag link end body while being threaded in or out drawing
The body of rod, reaches the regulation of length.
Further, the middle part of the drag link body is provided with peep hole and instrument clamping face.
Further, the latch assembly includes lock washer group, nut and fuse；The lock washer group includes upper
Lock washer and lower lock washer.
Further, the left and right two ends of drag link body are provided with axial groove, the groove and institute on the upper lock washer
If ears structure be engaged；The screw thread of the drag link end body is provided with keyway, the radial direction boss phase with the lower lock washer
Coordinate；The contact surface of the upper lock washer and lower lock washer is provided with teeth engaging structure, and is compressed by the nut；
The fuse tightens the nut and the upper lock washer, the upper and lower lock washer is not relatively rotated,
It is achieved thereby that drag link body is not relatively rotated with drag link end body, play a part of locking fixation.
Further, the nut is provided with fuse hole, and the upper lock washer is provided with monaural perforate, the insurance
Silk passes through the fuse hole and the monaural perforate and tightens.
Further, the gusset plate is connected on plane beam structural member and bracket by way of riveting.
Technical scheme also includes：
A kind of installation method for controlling board bracket, between bracket and plane beam structural member at least one at be using described above
Mounting structure.
Tie component of the present invention is the structure of a kind of adjustable length, radially variable, in specific application, effectively
Reduce the design and manufacture difficulty of each connector.Specifically, the pull bar of circular cross-section has the pull bar than square-section
More preferable intensity and ability to bear, it is to avoid the mount stress that rigid connection is brought, reduce the corrosion of working stress；By
The pendulum angle of aligning oscillating bearing makes pull bar radially adjustable relative to gusset plate；The design that matching thread formula loosens pull bar is capable of achieving
The fine setting of pull bar length, reduces installation difficulty, can accurately adjust the locus of bracket.

Touch and hole alignment, be fitted close dextrorotation drag link end body and gusset plate 21 with bolt 308, packing ring 309, self-locking nut 310.Using phase
Same mode, remaining pull bar is connected with the gusset plate on control board bracket respectively, realizes the phase of control board bracket and aircraft girder
Fixation to position.
Adjusting yoke part, makes bracket reach accurate assembly position, and concrete operations mode is：It is rotated both clockwise and counterclockwise
Drag link body 302, the depth that drag link end body in left and right screws in drag link body can simultaneously diminish or become greatly, the length of pull bar or shorten；
Rotated using the axle center self adaptation of aligning oscillating bearing 312, the relative position and angle of bracket can be adjusted.Drawn by 8
The ears of upper lock washer 303 after the position of adjustment control board bracket reaches final Installation posture, are snapped in pull bar by the regulation of bar
In the fluting of the end of body 302, and the lower lock washer 304 of the keyway of drag link end body 307 will be stuck in it has been axially moveable, with upper locking
Packing ring 303 is engaged, and screws the nut 306 with fuse hole, tightly engages upper and lower lock washer；Again by fuse 305 successively
The hole on hole and the outside monaural of upper lock washer 303 through on fuse hole nut 306, tightens fuse, it is ensured that pull bar
It is locking between termination and drag link body, upper and lower lock washer.
Specific embodiment of the invention has been described in detail above, but it is intended only as example, and the present invention is not limited
It is formed on particular embodiments described above.To those skilled in the art, any equivalent modifications carried out to the present invention and
Replacement is also all among scope of the invention.Therefore, the impartial conversion made without departing from the spirit and scope of the invention and
Modification, all should be contained within the scope of the invention.
