Description
Technical field
The utility model belongs to clamping device technical field, relates in particular to a kind of high locked bolts nut assembly installation folder
Tool.
Background technology
Bolt and nut component is very common in daily production process, and in aviation field, high locked bolts nut assembly
It is indispensable.There are the twistings driving parts such as hexagonal, 12 jiaos or cross recess, plain bolt, nut peace in plain bolt head
For twisting driving part respectively in the both sides of interlayer, it is more convenient to operate during dress.And the head of certain high locked bolts is without twisting device,
Only in tail portion there are one interior hexagonal hole, the twisting position both when high locked bolts, nut assembly are installed is located at the homonymy of interlayer,
The equipment such as torsion testing machine can not be used, it is necessary to could install using Special gun-type tool.And there is knot in existing specific purpose tool
Structure is complicated, inconvenient, stability is poor, the drawbacks such as inefficient, can not meet existing installation requirement.
Invention content
A kind of simple in structure, the easy to operate, stabilization provided the purpose of the utility model is to overcome disadvantages mentioned above can
It leans on, the high locked bolts nut assembly installs fixture of high-efficiency high-quality.
The utility model aim and its technical problem underlying is solved using following technical scheme to realize：
The high locked bolts nut assembly installs fixture of the utility model, including outer shaft, inner shaft, reducing sleeve, wherein：In outer shaft
Portion is separably set with inner shaft, and reducing sleeve is sleeved on by the interior hexagonal hole of end in the hexagonal prisms of inner shaft front end, inner shaft end
End is provided with screw thread, compressed spring is equipped between reducing sleeve and inner shaft, and compressed spring is placed in inside reducing sleeve, before reducing sleeve
Hexagon is connected in the square hole at end.
Above-mentioned high locked bolts nut assembly installs fixture, wherein：Inner shaft is mounted on the inside of outer shaft by bearing and baffle ring,
And bearing and baffle ring are placed in the end of outer shaft.
Above-mentioned high locked bolts nut assembly installs fixture, wherein：Hexagon is welded in the square hole of reducing sleeve front end.
The utility model compared with the existing technology has clear advantage and advantageous effect.By above technical scheme it is found that
In the high locked bolts nut assembly installs fixture of the utility model, inner shaft is separably set with inside outer shaft, inner shaft passes through axis
The inside that outer shaft is mounted on baffle ring is held, and bearing and baffle ring are placed in the end of outer shaft, realize outer shaft and are fixed on torsion test
It is rotated freely in machine host rack by motor through speed reducer driving energy both forward and reverse directions, and inner shaft is static；Interior shaft end is provided with spiral shell
Line is fixed on using nut on torsion testing machine main frame, reliable and stable；Compression bullet is installed between reducing sleeve and inner shaft
Spring, and compressed spring is placed in inside reducing sleeve, is eliminated the axial displacement generated when bolt, nut assembly installation, is worked well.When
During without using reducing sleeve, compressed spring, hexagon, torsion testing machine embodies its conventional torsion function；When use reducing sleeve,
High locked bolts, Closely locking nut component installation function can be realized after compressed spring, hexagon.In short, the utility model structure is simple
Single, easy to operate, reliable and stable, high-efficiency high-quality is suitble to promoting the use of for high locked bolts nut assembly installation.

Specific embodiment
Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes high locked bolts nut assembly installation folder
Have specific embodiment, structure, feature and its effect, be described in detail as after.
Referring to Fig. 1, the high locked bolts nut assembly installs fixture of the utility model, including outer shaft 1, inner shaft 2, reducing sleeve 3,
Wherein：Inner shaft 2 is separably set with inside outer shaft 1, reducing sleeve 3 is sleeved on 2 front end of inner shaft by the interior hexagonal hole of end
In hexagonal prisms, 2 end of inner shaft is provided with screw thread, compressed spring 4 is equipped between reducing sleeve 3 and inner shaft 2, and compressed spring 4 is put
Inside reducing sleeve 3, hexagon 5 is connected in the square hole of 3 front end of reducing sleeve.Pacified by bearing 6 and baffle ring 7 at 2 middle part of inner shaft
Mounted in the inside of outer shaft 1, and bearing 6 and baffle ring 7 are placed in the end of outer shaft 1.Hexagon 5 is welded on 3 front end square hole of reducing sleeve
It is interior.
In use, referring to Fig. 2, first outer shaft 1 is fixed on torsion testing machine and positive and negative through speed reducer driving energy by motor
Direction rotates freely, and 2 end of inner shaft is fixed on using nut on torsion testing machine main frame；High locked bolts are passed through into folder again
Layer, Closely locking nut with hand is screwed into high locked bolts until it is stubborn it is motionless until, high locked bolts bar tail portion is made to penetrate in hexagon 5,
Six side's twisting positions of Closely locking nut, axial movement torsion testing machine activity folder are clamped using the scroll chuck 8 of torsion testing machine
Head applies certain axial force to high locked bolts, Closely locking nut component；Then by torsion testing machine drive outer shaft 1 rotate and
Inner shaft 2 is static, and six side's twisting positions of Closely locking nut are twisted into two parts, and high locked bolts, Closely locking nut component is made to be mounted on interlayer i.e.
It can.The utility model is simple in structure, easy to operate, reliable and stable, high-efficiency high-quality, is suitble to pushing away for high locked bolts nut assembly installation
It is wide to use.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, it is any without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model to above example
Any simple modification, equivalent change and modification made, in the range of still falling within technical solutions of the utility model.
