Abstract
The invention provides an internal-hexagonal anti-rotation self-locking retainer ring and belongs to the technical field of self-locking threaded connection. The internal-hexagonal anti-rotation self-locking retainer ring comprises a part body (1) which is in the shape of a short pipe with one end sealed. An internal-hexagonal hole (2) coinciding with the short pipe in central axis is formed in the sealed end of the short pipe. An external thread (4) is arranged on the outer cylindrical face of the short pipe. Concave deformed pits (3) evenly distributed along the circumference are formed in the inner wall of the short pipe. Screwing notches (5) evenly distributed along the circumference are formed in the end face of the non-sealed end of the short pipe. The internal-hexagonal anti-rotation self-locking retainer ring not only has the advantage of a self-locking function, but also has the advantage of the capacity of preventing rotation. The internal-hexagonal anti-rotation self-locking retainer ring is high in strength, firm and reliable and connection and especially suitable for limiting the axial position of a part in a hole after the part in the hole is assembled, and can be used for other occasions where axial loads are large.
Description
Technical field
The present invention relates to six side's anti-rotation self-locking back-up rings in one, belong to self-locking thread connection technology field.
Background technology
In hole after part assembling, it will usually use circlip for hole to carry out spacing to part axial location in hole, owing to existing circlip for hole wall is thin, intensity is low, easily lost efficacy under the effect of axial impact force.Therefore, when axial load is bigger, use existing circlip for hole that the axial location of part in hole is carried out spacing mode and can not meet the needs of use.
Summary of the invention
It is an object of the invention to: provide a kind of the axial location of part in hole can be carried out spacing, intensity is higher, prevent part rotation and can bear axial load impact a kind of in six side's anti-rotation self-locking back-up rings, thus overcome the deficiencies in the prior art.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
Six side's anti-rotation self-locking back-up rings in a kind of, including part noumenon, the short tube shape being shaped as one end closing of described part noumenon, short tube is closed one end and is provided with the interior hexagonal hole overlapped with short tube axis, the external cylindrical surface of short tube is provided with external screw thread, and the inwall of short tube is provided with the depressed deformation hole being uniformly distributed along the circumference；The end face of the unclosed one end of short tube be provided be uniformly distributed along the circumference screw breach.
In aforementioned in six side's anti-rotation self-locking back-up rings, described depressed deformation hole is circumferentially uniformly distributed 2～4, and depressed deformation hole is spheroid impression, forms local crowning deformation at the external screw thread that depressed deformation hole is corresponding.
In aforementioned in six side's anti-rotation self-locking back-up rings, end face inner bore and the outer bore edges of the unclosed one end of described short tube are equipped with chamfering.
In aforementioned in six side's anti-rotation self-locking back-up rings, described short tube is closed the interior outer bottom edge of one end and is equipped with arc chord angle.
The beneficial effect of employing technique scheme:
1
, compared with prior art, the present invention takes to produce bulge-structure outside at 2～4 in external screw thread circumference on the back-up ring of hole, there is the deformed threads of little scope in the external screw thread making hole back-up ring, when the external screw thread after deformation is screwed into the base part of band internal thread hole, the female thread of base part tightly embraces the hole back-up ring that external screw thread is slightly deformed, so that it is interior, externally threaded junction produces locking torque, the base part making band internal thread hole is firmly connected with six side's anti-rotation self-locking back-up rings in one, the most both good locking effect can have been played, it is achieved thereby that auto-lock function, and the interior hexagonal hole of part prevents the rotation of part, moving axially of anti-Sealing shield ring part；Owing to interior six side's anti-rotation self-locking back-up rings are to threaded with matrix, it is possible to ensure that it has enough intensity to bear going out of axial load.
2
, compared with prior art, the present invention not only has an advantage of auto-lock function, but also has the advantage of ability preventing from rotating.
3
, compared with prior art, intensity of the present invention is high, firm and reliable connection, is particularly suitable in hole, after part assembling, carrying out spacing to part axial location in hole, and can be used for other and have the larger axis occasion to load.

Detailed description of the invention
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as any limitation of the invention.
As shown in Figure 1, six side's anti-rotation self-locking back-up rings in a kind of, including part noumenon 1, the short tube shape being shaped as one end closing of described part noumenon 1, short tube is closed one end and is provided with the interior hexagonal hole 2 overlapped with short tube axis, the external cylindrical surface of short tube is provided with external screw thread 4, and the inwall of short tube is provided with the depressed deformation hole 3 being uniformly distributed along the circumference；The end face of the unclosed one end of short tube be provided be uniformly distributed along the circumference screw breach 5.Depressed deformation hole 3 is circumferentially uniformly distributed 2～4, and depressed deformation hole 3 is spheroid impression, cheats at depressed deformation and forms local crowning deformation 6 at the external screw thread 4 of 3 correspondences.End face inner bore and the outer bore edges of the unclosed one end of short tube are equipped with chamfering 7.Short tube is closed the interior outer bottom edge of one end and is equipped with arc chord angle 8.
Embodiment
When implementing the present invention, first processing part noumenon 1, then threading 4 on the cylindrical of part noumenon 1, and part noumenon 1 center process in hexagonal hole 2, then existing flaring or impact style is used to extrude 2～4 depressed deformation holes 3 on the inwall at the external screw thread place of part noumenon 1, the external screw thread on part noumenon 1 outer surface is made to produce local crowning deformation 6 by depressed deformation hole 3, deformation is as shown in Figure 2, from Figure 2 it can be seen that externally threaded tooth depth is raised up δ highly by original height (in figure shown in dotted line).Owing to creating local crowning deformation on screw thread, self-locking moment during connection, can be produced；Interior hexagonal hole has the effect preventing rotating.For convenient disassembly in use, 2～8 can be processed on the end face of part noumenon 1 and screw breach, it is simple to by six side's anti-rotation self-locking back-up rings in instrument handling.
In order to prevent part from cracking at wedge angle when heat treatment process, the sharp corner at part noumenon 1 uses chamfering 7 or arc chord angle 8 transition。
