Description
Technical field
The present invention relates to liquid stop nuts to assemble application method, belongs to threaded connector field.
Background technology
In high-frequency vibration or impact device, need using stop nut connection fastening.Currently, common stop nut
Mechanical stop nut is mostly used greatly, and mechanical stop nut has the defect of the following aspects in use：
（1）When in use due to mechanical stop nut, the part of screw-thread fit is only threaded always is engaged on one side, this
For sample in prolonged high-frequency vibration operation process, nut still has the defect of loosening, can not play permanent anti-loosening purpose；
（2）Existing stop nut structure is all more complicated, and appearance and size is bigger, for the limited position of installation space
Requirement is just cannot be satisfied, adaptability is poor；
（3）Existing stop nut manufacturing cost is higher, for the field of employment of big demand, greatly increases whole equipment
Cost；
（4）There is inconvenience for existing stop nut assembly use.
Shear thickening liquid, English name Shear Thickening Fluid are risen in the U.S. and Britain at the beginning of 21 century and in
A kind of novel protective material that state further develops freely left floating many special particles in " shear thickening liquid ", he is included
Nanometer spherical particle be one of nonmetallic materials most hard in nature it flexibility is usually presented, and when being impacted
Robustness is presented.It is widely used in physical protection equipment currently as a kind of novel material.
Therefore, the application applies to shear thickening liquid on the basis of traditional nut in the stop nut of the application,
Play the locking purpose of good vibrationproof.
Invention content
It is an object of the present invention to provide a kind of liquid stop nut and assembly application methods, this liquid stop nut will be by that will cut
It cuts thickening liquid and nut assembly matches, be fixedly connected for bolt, ensure that bolt and nut cooperation by severe impact
Or when vibration, very locking purpose can be played.
In order to realize above-mentioned technical characteristic, the object of the present invention is achieved like this：Liquid stop nut, it includes using
In the nut glass holder for holding shear thickening liquid；It is equipped in the inner cavity of nut glass holder for being blocked to shear thickening liquid
Nut body；The outer cover of the nut body and nut glass holder is equipped with the locking mechanism for preventing the two from rotating；The nut
Glass holder, nut body and screw rod match constituted inside cavity and are contained with shear thickening liquid.
The nut glass holder uses the first outer-hexagonal prism, is machined with respectively inside the first outer-hexagonal prism and nut body
Matched first internal thread segment is machined with and matched second internal thread of screw rod in the cavity end of the first internal thread segment
Section.
The nut body includes the second outer-hexagonal prism, and the other end of the second outer-hexagonal prism is third outer-hexagonal rib
The other end of column, the third outer-hexagonal prism is the first threaded post；The second outer-hexagonal prism, third outer-hexagonal prism and
The center of first threaded post is machined with perforative third internal thread segment, and the third internal thread segment is matched with screw rod.
The appearance and size of the third outer-hexagonal prism is identical as the size of the first outer-hexagonal prism of nut glass holder.
The locking mechanism uses cylinder, and the first outer-hexagonal prism with nut glass holder is machined at the center of cylinder
Matched interior hexagonal through-hole, in the outer wall upper edge of cylinder, its radial equipartition is machined with multiple tightening screw holes, the clamp screw
Holding screw is installed on hole.
It is set with gasket on screw rod between nut glass holder and the turret head end face of screw rod.
The nut glass holder and the matched position of screw rod are provided with the raw material for being sealed to shear thickening liquid
Band.
The matched position of the first internal thread segment of the first threaded post and nut glass holder of the nut body, which is provided with, to be used for
The raw material band that shear thickening liquid is sealed.
The nut body and screw rod mated position are provided with the raw material band for being sealed to shear thickening liquid.
The assembly application method of liquid stop nut described in any one, it includes the following steps：
Step1：Screw rod is sequentially passed through to the through-hole for waiting for connecting elements, and gasket is sleeved on screw rod；
Step2：Nut glass holder is sleeved on screw rod, and makes the outward opening of the first internal thread segment；
Step3：Shear thickening liquid is positioned over inside the first internal thread segment of nut glass holder；
Step4：By nut body screw set on screw rod, and the first threaded post is made to be matched with the first internal thread segment；
Step5：Locking mechanism is mounted on outside nut glass holder and nut body, and the two is fixed.
The method have the advantages that：
1, effective anti-loosing effect can be played by using above-mentioned liquid stop nut, in use, do not had
Under the operating mode of impact or vibration, shear thickening liquid will be in inside nut body and the matched thread pitch of screw rod, and
It is in working fluid state always；When screw rod, nut glass holder or nut body impacted and vibration processes in, be packaged
The shear thickening liquid in portion is just being become tough and tensile incomparable by the moment impacted in the cavity, and can be fast along fabric by impact force
Speed spreads out, and then fills nut body and the matched thread pitch of screw rod, increases frictional force between the two；Finally,
Achieve the effect that locking.
2, by the cooperation between the nut glass holder and nut body can to the shear thickening liquid of inside cavity into
The effective sealing of row and encapsulation, make it be always positioned at nut body and the matched thread pitch of screw rod.
3, positioning can be matched with the end face of nut glass holder by the third outer-hexagonal prism being arranged on nut body.
4, it can easily be matched, and then ensure that nut with spanner by the second outer-hexagonal prism on nut body
Body carries out precession.
5, pass through the appearance and size of third outer-hexagonal prism energy identical as the size of the first outer-hexagonal prism of nut glass holder
It is enough that locking mechanism is easily set with outside it, and then simultaneously lock nut glass holder and nut body, prevent it from opposite turn occurs
It is dynamic, and loosen.
