Description
Technical field
The present invention is a kind of to squeeze hook to the miniature bearing wedge that miniature bearing takes out suitable for high-accuracy mechanical field and pull out device.
Background technology
On aircraft in certain precision gear components, miniature bearing is installed on part in blind hole, the working time needs long
Bearing is replaced, since miniature bearing internal diameter is especially small, existing bearing puller can not work on the market at present.These installations are micro-
The part that profile shaft is held, such as accurate planetary gear set price are very expensive, cannot have when it requires and choosing bearing to part
Any microlesion, at present, common bearing method of choosing be with pad mouth method clamping gear, make it is multiple draws hook, with draw hook according to
Secondary draw takes bearing inner ring, ball, outer shroud, then repairs remaining outer race in gear with carbide drill, and such dismounting is not
But it is high to the technology requirement of operating personnel, but also may be by damage parts, dangerous.
Invention content
The object of the present invention is to provide one kind can ensure part stablize clamping, it is simple in structure, easy to use, do not damage zero
The miniature bearing wedge of part squeezes hook and pulls out device.
The technical scheme is that complete as follows, miniature bearing wedge squeezes hook and pulls out device, it is characterised in that：Have two
Block can be by the floating clamping plate that aircraft electric parts packs tightly, on a craft port outer wall of two pieces of floating clamping plates there are one connections
Wave type springs piece, with low fastening station, installation is there are one support buckle closure upwards in the clamping opening of two pieces of floating clamping plates, in buckle closure
From top center hole, inwardly lower installation is there are one rhampotheca, higher than buckle closure installation there are one nut on rhampotheca, in nut and buckle closure
Between washer is installed, set in the via of rhampotheca and buckle closure inner horizontal plate there are one up big and down small chock, in rhampotheca apical pore
To the installation of chock top surface, there are one screws, and there are one little springs for connection between rhampotheca and chock, are equipped on buckle closure outer wall saturating
Bright observation window.
The present invention have structure is simple and direct, easy to operate, clamping is reliable, protection parts while can effectively improve miniature bearing
The advantages of efficiency of choosing.

Specific embodiment
Embodiment is described in detail with reference to the figures above, it includes two pieces can be by floating clamping plate that aircraft electric parts packs tightly
1, connection is there are one wave type springs piece 2 on a craft port outer wall of two pieces of floating clamping plates, in two pieces of floating clamping plates
In clamping opening with low fastening station upwards installation there are one support buckle closure 3, in buckle closure from top center hole inwardly it is lower install there are one
Rhampotheca 4, higher than buckle closure installation, there are one nuts 9 on rhampotheca, and washer 8 is equipped between nut and buckle closure, in rhampotheca and button
Up big and down small chock 6 there are one being set in the via of lid inner horizontal plate, to the installation of chock top surface, there are one screws in rhampotheca apical pore
7, there are one little springs 5 for connection between rhampotheca and chock, and transparent windows 10 are equipped on buckle closure outer wall.
As when the planetary gear set needs to take out miniature bearing therein in aircraft, which is put among floating clamping plate
Afterwards, floating clamping plate is clamped with vice, the main vice of upper boss card of floating clamping plate prevents tooling from deviating from, lower boss holds zero
Part prevents part from deviating from, and two pieces of floating clamping plates are combined by Wave shape spring reed, and part is included wherein, realizes five point locations,
Ensure that part is injury-free in repair procedures.Then rhampotheca is goed deep into miniature bearing, turns screw, screw bottom top downwards
It chock and is pressed down against rhampotheca, the hook of rhampotheca bottom is expressed to miniature bearing lower end, bearing is hooked, the effect of little spring is
Chock is tied up in rhampotheca bottom, in case chock slides.Then buckle closure is covered, puts gasket, nut is screwed on rhampotheca.Finally turn
The nut on dynamic rhampotheca top, by rhampotheca integrally upward turn, so as to be moved upwards with bearing, four window observables on buckle closure
Working condition.For the stationarity for ensureing to choose upwards, the corresponding position of gib head and chock is can adjust, so as to which bearing be taken out.It should
Device is stablized with clamping, and working efficiency is high and the advantages of ensureing part integrity.
