Abstract
The invention relates to a self-locking threaded sleeve which comprises a nut main body, wherein an external thread part is arranged on the exterior of the nut main body; an internal thread part is arranged on the interior of the nut main body; an interference thread is arranged on the external thread part; a mounting technical block is arranged at one end of the external thread part; the mounting technical block and the nut main body are integrally formed; a locking part is arranged on the external thread part; a closing section is arranged on the locking part of the external thread part; the closing section and the external thread part form the exterior of the self-locking threaded sleeve. According to the self-locking threaded sleeve provided by the invention, the mounting technical block and the locking part are arranged, a threaded sleeve is mounted in a substrate and a locking torque is generated by the internal thread part under the actions of an axial force and the locking part, so that a mounting self-locking function is achieved, no special mounting tool is required, the mounting efficiency is increased, the structure is simple, the use is convenient, the reliability is high, the automatic assembling is realized and the self-locking threaded sleeve can be widely applied to the assembling for the aerial and automobile engine structural components.
Description
Technical field
The invention belongs to mechanical manufacturing field, specifically relate to a kind of self-locking thread insert.
Background technique
At present, in the many structural members of machinery industry connect, threaded swivel nut is usually adopted to connect.And nut is mechanical connecting structure conventional in prior art, be widely used in various machinery industry, particularly in aviation and automobile industry engine design manufacture process, along with continuous renewal and the development of technology, a large amount of use magnalium matrix is started in prior art, use interference nut in a large number during assembling simultaneously, adopt interference nut can damage matrix because mounting torque is excessive when mounted, simultaneously can only once mounting.Must tapped hole be strengthened when needs are ressembled, adopt simultaneously and strengthen interference nut, and repeat at most assembling once.Like this great difficulty is brought to maintenance, even cause changing matrix.Therefore, the Placement that a kind of anti-loosing effect is good, installation efficiency is high is needed to be current problem demanding prompt solution.
Summary of the invention
The technology that the present invention will solve is for deficiency of the prior art, there is provided a kind of structure simple, stable performance, there is installation locking torque, mounting point reliability can be ensured, swivel nut in installation process can also be avoided to rotate the swivel nut that can not damage and install matrix, specifically a kind of self-locking thread insert simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of self-locking thread insert, comprise nut body, described nut body outside is outside thread part, inside is internal thread part, described outside thread part is set to interference thread, described outside thread part one end is provided with mounting process block, described mounting process block and nut body are formed in one, described outside thread part is provided with locking position, described locking position for being provided with closing in section in described outside thread part, and described closing in section and outside thread part form the outside of self-locking thread insert.
Further, described closing in section is arranged at outside thread part middle part.
Further, in described closing in section outer cover, seal ring is housed.
Adopt a kind of self-locking thread insert of the present invention, its beneficial effect is: owing to being provided with mounting process block and locking position on swivel nut, swivel nut is arranged in matrix, under the effect of axial force with locking position, internal thread part produces locking torque, thus has installation auto-lock function, does not need special installation tool simultaneously, thus improve installation efficiency, its structure is simple, easy to install, and reliability is high, can realize automatic assembling.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Structural representation when Fig. 2 is using state of the present invention.
Shown in figure: 1-outside thread part, 2-internal thread part, 3-mounting process block, 4-closing in section, 5-seal ring, 6-matrix.
Embodiment
As shown in Figure 1, a kind of self-locking thread insert of the present invention, comprise nut body, described nut body outside is outside thread part 1, inside is internal thread part 2, described outside thread part 1 is set to interference thread, described outside thread part 1 one end is provided with mounting process block 3, described mounting process block 3 is formed in one with nut body, described outside thread part 1 is provided with locking position, described locking position for being provided with closing in section 4 in described outside thread part 1, and described closing in section 4 forms the outside of self-locking thread insert with outside thread part 1.
Further, described closing in section 4 is arranged in the middle part of outside thread part 1.
Further, in described closing in section 4 outer cover, seal ring 5 is housed.
In actual fabrication process, different metal can be selected as swivel nut material according to different needs, preferably select stainless steel material to carry out processing and fabricating, mounting process block 3 controls according to the matrix 6 of different size and usage requirement adding man-hour.Simultaneously coating dry lubricant in the internal thread part 2 of the good self-locking thread insert inside of processing and fabricating can prevent rotation from killing situation.As shown in Figure 2, in as installed using process, be first screwed into by swivel nut in matrix 6, then twisted into two parts by mounting process block 3, then swivel nut is fixed in matrix 6 safely and reliably.Owing to being provided with locking position, in closing in section 4 outer cover, seal ring 5 is housed simultaneously, so just can effectively prevents swivel nut from loosening.In addition, because swivel nut outside thread part 1 adopts interference thread, external thread part part 1 is provided with closing in section 4, under the effect of axial force, makes inner internal thread part 2 produce locking torque by closing in section 4, thus realize auto-lock function.As long as common stud is screwed into this self-locking thread insert can normally assemble.As can be seen here, adopt self-locking thread insert of the present invention, its structure is simple, easy to install; reliability is high; there is installation auto-lock function, play the effect of location simultaneously, mounting point reliability can be ensured; also can protect matrix 6 simultaneously; in installation process, swivel nut rotates to damage and installs matrix 6, thus can not damage by available protecting matrix 6, extends the service time of matrix 6; self-locking thread insert of the present invention does not need special installation tool, easily realizes assembling automatically.Thus improve installation efficiency, extensively can promote the use of in the assembling of aviation and Vehicle Engine Structure part, there is good economic benefit and social benefit.
Protection scope of the present invention is not limited only to the technological scheme disclosed in embodiment; the foregoing is only better embodiment of the present invention; not in order to limit the present invention; every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
