Abstract
The invention discloses a kind of part without twisting self-locking method and without twisting structure self-locking thread insert, it is outside anti-rotating hole at the internal thread circumferentially disposed 2~4 without twisting structure self-locking thread insert, the external screw thread of hole back-up ring is set to occur deformed threads, when the external screw thread after deformation is screwed into the base part with internal thread anti-rotating hole, the internal thread of base part tightly embraces the hole back-up ring that external screw thread is slightly deformed, so that the junction of internal and external screw thread produces locking torque.The present invention using without twisting design, three anti-rotating holes act on assembling during, spacing effect is played, internal thread is by deformation, heat treatment reinforcement, so that product, which is played, locks locking effect.
Description
Technical field
The invention belongs to self-locking thread connection technology field, more particularly to a kind of part without twisting self-locking method and
Without twisting structure self-locking thread insert.
Background technology
After component assembly, it will usually the effect tightened using twisting structure to product, but in currently available technology,
Also without the relatively good method tightened without twisting structure to product, therefore, it is necessary to carry out the research of this respect and open
Hair.
The content of the invention
It is an object of the invention to provide can carry out that spacing, intensity is higher, prevent zero by the axial location of part in device to hole
The rotation of part and the locking effect of locking, and can bear axial load impact a kind of part without twisting self-locking method and without pulling
Structure self-locking thread insert is twisted, so as to overcome the deficiencies in the prior art.
What the present invention was realized in：
A kind of part without twisting self-locking method, it using one kind without twisting structure self-locking thread insert, at this without twisting structure
Outside anti-rotating hole at the internal thread circumferentially disposed 2~4 of self-locking thread insert, makes the external screw thread of hole back-up ring occur deformed threads, when
When external screw thread after deformation is screwed into the base part with internal thread hole, it is light that the internal thread of base part tightly embraces external screw thread
The hole back-up ring of Light deformation so that internal and external screw thread junction produce locking torque, make the base part with internal thread hole with
This is firmly connected without twisting structure self-locking thread insert, realizes auto-lock function, while the rotation of part is prevented by the anti-rotating hole of part,
The axial movement of anti-Sealing shield ring part.
It is a kind of that without twisting structure self-locking thread insert, it includes part noumenon, and the part noumenon is provided with external screw thread and internal thread,
Internal thread is circumferentially with anti-rotating hole outside at 2~4, and deformed area is provided with the rear of internal thread.Wherein, the quantity of anti-rotating hole
For 3, along the circumferential uniform according to hexagonal angle spacing of internal thread.
Technical scheme is designed using twisting, three anti-rotating holes act on assembling during, play
Spacing effect, internal thread is by deformation, heat treatment reinforcement, so that product, which is played, locks locking effect.
Compared with prior art, the present invention not only has the advantages that auto-lock function to the present invention, but also with preventing rotation
Ability advantage.Intensity of the present invention is enough, firm and reliable connection, is particularly suitable in hole after component assembly, to part in hole
Interior axial location progress is spacing, and available for other occasions with larger axial load.
Brief description of the drawings
Fig. 1 is the present invention without twisting structure self-locking thread insert structural representation；
Fig. 2 is the left view in Fig. 1.
Description of reference numerals：1- part noumenons, 2- external screw threads, 3- internal threads, 4- anti-rotating holes, 5- deformed areas.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：
The present invention devises such a without twisting structure self-locking thread insert, and it includes part noumenon 1, and the part noumenon 1 is set
There are external screw thread 2 and internal thread 3, provided with the outside anti-rotating hole 4 being uniformly distributed along the circumference at 3 in internal thread 3, anti-rotating hole 4 is along interior spiral shell
The circumference of line 3 is uniform according to hexagonal angle spacing.Deformed area 5 is provided with the rear of internal thread 3.
The present invention is implemented, and the present invention takes outside bulge-structure at the circumferential generation 2~4 of internal thread 3
Anti-rotating hole 4, makes the external screw thread 2 of hole back-up ring occur the deformed threads of small range, and the external screw thread 2 after deformation is screwed into interior spiral shell
During the base part of pit, the internal thread of base part tightly embraces the hole back-up ring that external screw thread 2 is slightly deformed, so that
The junction of internal and external screw thread produces locking torque, makes the base part with internal thread hole with the present invention without twisting structure self-locking
Swivel nut is firmly connected, and so can both play good locking effect, it is achieved thereby that auto-lock function, and three anti-rotating holes of part
4 prevent the rotation of part, the axial movement of anti-Sealing shield ring part.Because self-locking thread insert and matrix are to be threadedly coupled, Neng Goubao
Demonstrate,proving it has enough intensity to bear going out for axial load.
Certainly, it is the concrete application example of the present invention above, the present invention also has other embodiments, all using equivalent
Replacement or the technical scheme of equivalent transformation formation, all fall within protection domain of the presently claimed invention.
Claims (3)
