Abstract
The invention discloses a miniature bearing wedge squeezing hook extractor. The miniature bearing wedge squeezing hook extractor comprises two floating plywoods which are capable of wrapping tightly an airplane electric part, a wavy spring sheet is connected to the outer wall of a butt-joint end port of the two floating plywoods, a cap-shaped buckle cover is upwards installed in a clamping opening of the two floating plywoods by using an up-down clamping platform, a hook cover is installed downwards from the top center hole inside the buckle cover, a nut is installed in the position, higher than the buckle cover, of the hook cover, a gasket is installed between the nut and the buckle cover, a wedge with a big bottom and a small end is internally arranged in a via-hole of the hook cover and an inner cross plate of the buckle cover, a bolt which faces the top face of the wedge is installed in the top hole of the hook cover, a small spring is connected between the hook cover and the wedge, and a transparent observation window is arranged on the outer wall of the buckle cover. The miniature bearing wedge squeezing hook extractor has the advantages of being simple in structure, convenient to operate, reliable in clamping, and is capable of effectively improving the extraction efficiency of a miniature bearing and protecting parts at the same time.
Description
Technical field
The present invention is that a kind of miniature bearing wedge taken out to miniature bearing suitable for high-accuracy mechanical field squeezes hook and pulls out device.
Background technology
On aircraft in some precision gear components, miniature bearing is installed on part in blind hole, the working time needs long
Bearing is changed, because miniature bearing internal diameter is especially little, bearing puller cannot work present on current market.These installations are micro-
The part that profile shaft holds, such as accurate planetary gear set price is very expensive, can not have to part when it requires and choosing bearing
Any microlesion, at present, conventional bearing method of choosing be with pad mouth method clamping gear, make it is multiple draws hook, with draw hook according to
Secondary drawing 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 technical requirements of operator, but also may be by damage parts, dangerous.
The content of the invention
It is an object of the invention to provide one kind ensure that the stable clamping of part, simple structure, it is easy to use, do not damage zero
The miniature bearing wedge of part squeezes hook and pulls out device.
The technical scheme is that what is completed as follows, miniature bearing wedge squeezes hook and pulls out device, it is characterised in that：Have two
The floating clamping plate that block can pack tightly aircraft electric parts, on a craft port outer wall of two pieces of floating clamping plates one is connected with
Wave type springs piece, uses low fastening station to be provided with a support buckle closure upwards, in buckle closure in the jaws of two pieces of floating clamping plates
From top center hole it is inside under a rhampotheca is installed, one nut is installed higher than buckle closure on rhampotheca, in nut and buckle closure
Between packing ring is installed, a up big and down small chock is provided with the via of rhampotheca and buckle closure inner horizontal plate, in rhampotheca apical pore
One screw is installed to chock top surface, a little spring is connected between rhampotheca and chock, be provided with buckle closure outer wall
Bright observation window.
The present invention can effectively improve miniature bearing while having simple and direct, easy to operate structure, clamping reliability, protection parts
The advantage of efficiency of choosing.

Specific embodiment
Embodiment is described in detail with reference to the figures above, it includes two pieces of floating clamping plates that can be packed tightly aircraft electric parts
1, a wave type springs piece 2 is connected with a craft port outer wall of two pieces of floating clamping plates, in two pieces of floating clamping plates
One support buckle closure 3 is installed upwards with low fastening station in jaws, in buckle closure from top center hole it is inside under be provided with one
Rhampotheca 4, a nut 9 is provided with rhampotheca higher than buckle closure, and packing ring 8 is provided between nut and buckle closure, in rhampotheca and button
A up big and down small chock 6 is provided with the via of lid inner horizontal plate, one screw is installed to chock top surface in rhampotheca apical pore
7, a little spring 5 is connected between rhampotheca and chock, transparent windows 10 are provided with buckle closure outer wall.
As when the planetary gearsets need to take out miniature bearing therein in aircraft, the part being put in the middle of floating clamping plate
Afterwards, floating clamping plate is clamped with vice, the main vice of upper boss card of floating clamping plate prevents frock from deviating from, and lower boss holds zero
Part, prevents part from deviating from, and two pieces of floating clamping plates are combined by Wave shape spring reed, by part comprising wherein, realizes five point locations,
Ensure that part is injury-free during repairing.Then rhampotheca is goed deep in miniature bearing, screw, screw bottom top is turned downwards
Chock and be pressed down against rhampotheca, the hook of rhampotheca bottom is expressed to into 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, pad is put, nut is screwed on rhampotheca.Finally turn
The nut on dynamic rhampotheca top, by the overall turn upwards of rhampotheca, so as to move upwards with bearing, four window observables on buckle closure
Working condition.For the stationarity for ensureing to choose upwards, the correspondence position of gib head and chock is can adjust, so as to bearing be taken out.Should
There is device clamping to stablize, and high working efficiency and ensure the advantage of part integrity.
