Description
Technical field
The application is related to guider during a kind of aircraft manufacturing field, specifically motor power bearing pin installation, especially
Suitable for lacking the step diameter of axle of chamfering in the guider do not installed in wide open space.
Background technology
Aircraft general assembly is in aircraft manufacturing flow and its important link, because aircraft general assembly work-in-process is empty
Between it is limited, assembly process is complicated, assembly difficulty is big, especially the assembling quality of the high Core Value part such as engine and assembling week
Phase will directly affect delivery quality and the cycle of aircraft.
Aircraft engine carries aircraft whole thrust by thrust pin bearing, and thrust pin coordinates with anchor bearing to be excessive, peace
It is high to fill precision, difficulty when bearing pin enters, lacks applicable guider.The guider that presently, there are is broadly divided into two major classes,
General monoblock type chamfering/rounding formula guide collar, such guider need the other end taking-up from product, are only applicable after being oriented to
Installed in part bearing pin；Another kind of is breakdown guider, and guider is spliced by several parts, entered by fastener
Row is fixed, and is decomposed after correcting, and because manipulation space is not open, difficulty is decomposed after correcting, and operating efficiency is low, especially inapplicable
The complicated Short Axis Kind of the mounting structures such as motor power pin uses.
The content of the invention
In order to lack accurate guiding when solving the installation of motor power bearing pin, easily there is product bump injury, enter position difficulty etc.
Problem, a kind of quick correcting when the application provides achievable motor power bearing pin installation, precisely enter position, protection in place, behaviour
Make easily installation method and guider, and different diameters of axle installations can be realized by changing the guide collar of different size
When guiding work.
A kind of motor power bearing pin installation and guide device, contains first assembly and the second component, it is characterised in that first
Component and the second component are symmetrical, are made up of respectively the semicircular guide collar of front end and the handle of rear end, described guide collar
Upside inner edge be an arc angling extended out；The downside of described guide collar is provided with locating slot, and described middle handle has
The flex point of protrusion, left and right handle are hinged at flex point, and forming a front end has the forceps-like arrangement of openings lead circle, in the handle of left and right
Between have back-moving spring connection, the internal diameter of the guide collar matches with the external diameter of motor power bearing pin.
In order to avoid motor power bearing pin and guide collar contact-impact and contact friction force is reduced, in the arc of guide collar
Directive wheel is also embedded with chamfering.
In use, above-mentioned guider is placed in the mounting seat of motor power bearing pin, on the downside of guide collar
Locating slot is directed to the center of circle and the center superposition of mounting seat upper installing hole and positioning；Motor power bearing pin is passed through into guiding
In the mounting hole of circle insertion mounting seat；The handle move toward one another of device is directed to, guide collar is opened and withdraws motor power pin
Axle.
The beneficial effect of the application is：Simple and reasonable, simple operation, it is directed to circle and is combined with handle mechanism,
The quick installation that common guide collar can not be realized, the guider decomposed are realized, and can be realized specific with reference to not wide open space
The shape of situation adaptability change handle etc., the fast and accurate installation for carrying out the complicated axle classes such as motor power pin of energy,
It is the large-scale apparatus assembling such as aircraft, the indispensable instrument of maintenance.According to the difference of motor power pin diameter, by transferring, pin can
To change the installment work that the guide collar of different-diameter carries out different size thrust pin.
The application is described in further detail with reference to embodiments：
Brief description of the drawings
Fig. 1 is the application motor power bearing pin guider structural representation.
Fig. 2 is motor power bearing pin installation method schematic diagram.
Explanation is numbered in figure：1 first assembly, 2 second components, 3 guide collars, 4 handles, 5 bearing pins, 6 arc anglings, 7 are oriented to
Wheel, 8 locating slots, 9 connecting pins, 10 back-moving springs, 11 motor power bearing pins, 12 mounting holes, 13 mounting seats.
Embodiment
Referring to accompanying drawing, the aircraft engine thrust bearing pin installation and guide device of the application, contain first assembly 1 and second group
Part 2, the component 2 of first assembly 1 and second is symmetrical, is made up of respectively the semicircular guide collar 3 of front end and the handle 4 of rear end.
In implementation, guide collar 3 and handle 4 can be integrative-structures, can also Split type structure as depicted.Guide collar 3 and handle 4
Between by connection pin connection.The advantages of Split type structure be can according to the different diameters of axle of motor power bearing pin it is convenient more
The guide collar of corresponding internal diameter is changed, facilitates the use of production scene.
The upside inner edge of guide collar 3 is an arc angling extended out 6, the internal diameter of its guide collar is divided into guide portion with leading
Straight area, play guiding and directly enter position effect with leading.Several directive wheels 7 are embedded with arc angling, directive wheel 7 is built in arc angling
On mounting groove in, can be formed, be symmetrically distributed in around the rubber wheel that own torque rotates by symmetrical three groups in embodiment
On the guide portion arc angling 6 of guide collar 2；The downside of described guide collar 3, that is, the another side of guide collar 3 are provided with
Locating slot 8, the locating slot 8 are engaged with the interface of the mounting seat 13 of motor power bearing pin 11；The described middle part of handle 4 has
The flex point of protrusion, be hinged by bearing pin 5 at the flex point of left and right handle, forming a front end has the forceps-like arrangement of openings lead circle,
There is back-moving spring 10 to connect among the handle of left and right, the internal diameter of the guide collar 3 matches with the external diameter of motor power bearing pin 11.
In use, above-mentioned guider is placed in the mounting seat 13 of motor power bearing pin 11, pass through guide collar 3
The locating slot 8 of downside is directed to the center of circle 3 and the center superposition of the upper installing hole 12 of mounting seat 13 and positioning；Pass through engine
Crane is installed aircraft engine is close to aircraft matrix, motor power bearing pin 11 is aligned installation and guide device；It will start
Machine thrust bearing pin 11 is inserted by guide collar 3 in the mounting hole 12 of mounting seat 13；The handle 4 for being finally directed to device closes in opposite directions
Motion, open guide collar 3 and the guider is withdrawn motor power bearing pin 11.
