Description
Technical field
The invention belongs to mechanical manufacturing fields, more particularly to six side's anti-rotation self-locking baffle rings in one kind.
Technical background
In hole after component assembly, it will usually axial position of the part in hole is limited using circlip for hole,
Since existing circlip for hole wall is thin, intensity is low, easily fail under the action of axial impact force.Therefore in axial load
When larger, it cannot meet what is used in a manner that the axial position of part in existing circlip for hole device to hole is limited
It needs.
Invention content
To overcome drawbacks described above, the technical problem to be solved in the present invention is to provide a kind of part progress that can either be in device to hole
Axial limiting prevents parts turn, and higher with intensity, can bear the anti-rotation self-locking baffle ring of larger axial load impact.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
Six side's anti-rotation self-locking baffle ring in one kind, including part noumenon, the shape of the part noumenon is the cylinder of one end closing
Shape, cylinder enclosed one end are equipped with the interior hexagonal hole overlapped with cylinder center line, and the external cylindrical surface of cylinder is equipped with external screw thread, cylinder
Inner wall be equipped be uniformly distributed along the circumference depressed deformation hole, depressed deformation hole quantity be 2~4；The depressed deformation hole is
Sphere impression cheats in depressed deformation and local crowning deformation is formed at corresponding external screw thread；On the end face of the unclosed one end of cylinder
Notch is screwed equipped with what is be uniformly distributed along the circumference, the quantity for screwing notch is 2~4；Position of the depressed deformation hole with screwing notch
It puts interlaced.
The end face inner bore and outer bore edges of described unclosed one end of cylinder are equipped with chamfering, chamfering 1X450。
The inside and outside base of described cylinder enclosed one end is equipped with arc chord angle, arc chord angle R3.
Using the advantageous effect of above-mentioned technical proposal:
（1）, compared with prior art, the present invention hole with taken on baffle ring circumferentially generated in outer threaded circular it is outside at 2~4
Bulge-structure makes the external screw thread of hole baffle ring that small-scale deformed threads occur, when deformed external screw thread is screwed into interior spiral shell
During the base part of pit, the internal thread of base part tightly embraces the hole baffle ring that external screw thread is slightly deformed, so as in making,
Externally threaded junction generates locking torque, makes the base part with internal thread hole and six side's anti-rotation self-locking baffle rings in one kind secured
Connection can both play good anti-loose effect in this way, realize auto-lock function；The interior hexagonal hole of part prevents turning for part simultaneously
It is dynamic, so as to the axial movement of anti-Sealing shield ring part；Since the present invention with matrix is to be threadedly coupled, therefore it is enough to ensure that it has
Intensity bears going out for axial load.
（2）, compared with prior art, intensity of the present invention is high, firm and reliable connection, particularly suitable for component assembly in hole
Afterwards, axial position of the part in hole is limited, and available for other occasions with larger axial load.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, but not as any limitation of the invention.
As shown in Figures 1 to 3, six side's anti-rotation self-locking baffle rings in one kind, including part noumenon 1, the shape of the part noumenon 1
For the cylindrical shape of one end closing, cylinder enclosed one end is equipped with the interior hexagonal hole 2 overlapped with cylinder center line, the external cylindrical surface of cylinder
External screw thread 4 is equipped with, the inner wall of cylinder is equipped with the depressed deformation hole 3 being uniformly distributed along the circumference, and the quantity in depressed deformation hole 3 is 2~4
It is a；Depressed deformation hole 3 is sphere impression, is cheated in depressed deformation and local crowning deformation 6 is formed at 3 corresponding external screw threads 4.Cylinder is not
The end face of closing one end screws notch 5 equipped with what is be uniformly distributed along the circumference, and the quantity for screwing notch 5 is 2~4.Depressed deformation hole 3
It is interlaced with the position that screws notch 5.The end face inner bore and outer bore edges of the unclosed one end of cylinder are equipped with chamfering 7, chamfering 7
For 1X450.The inside and outside base of cylinder enclosed one end is equipped with arc chord angle 8, fillet R3.
Self-locking retaining ring of the present invention first processes part noumenon 1 in processing, is then processed in the outer circle of part noumenon 1 outer
Screw thread 4, and the hexagonal hole 2 in the processing of 1 center of part noumenon, then use on the inner wall where the external screw thread of part noumenon 14
Existing flaring or impact style extrude 2~4 depressed deformation holes 3, make 1 appearance of part noumenon by depressed deformation hole 3
External screw thread on face generates local crowning deformation 6, and deformation is as shown in Figure 4.From fig. 4, it can be seen that externally threaded tooth height is by original height
Degree（In figure shown in dotted line）Raise up δ height.Due to producing local crowning deformation on screw thread, when connection, can generate self-lock force
Square；Interior hexagonal hole has effects that prevent rotation.For convenient disassembly when in use, can be processed on the end face of part noumenon 1
Go out 2~4 and screw notch 5, convenient for passing through six side's anti-rotation self-locking baffle rings in tool handling.
Part is cracked in heat treatment process in wedge angle in order to prevent, and chamfering 7 is used in the sharp corner of part noumenon 1
Or 8 transition of arc chord angle.
