Abstract
An axial compression thread self-locking nut comprises a nut wrenching section and a nut closing-in section, wherein more than two axial partition grooves are formed in the nut closing-in section, and a press groove is formed in the inner side of the end face of the nut closing-in section between every two partition grooves. The formed press groove enables inner threads of the nut adjacent to the press groove to produce same-direction slight deformation and meanwhile enables the nut closing-in section where the press groove is located to slightly deform towards the axis of the nut. According to a closing-in method of the axial compression thread self-locking nut, a stamping groove is formed in each partition end face through axial partition of the closing-in section of the self-locking nut, so that the inner threads of the nut adjacent to the press groove produces same-direction slight deformation and meanwhile the nut closing-in section where the press groove is located slightly deforms towards the axis of the nut. Compared with a transitional self-locking nut closing-in mode, deformation at the closing-in position is convenient to master and control, closing-in deformation degree can be also well mastered even if the outer wall of the nut is thick, and product quality is very stable.
Description
Technical field
The present invention relates to a kind of self-locking nut and closing method thereof, be specifically related to a kind of axial compression screw thread self-locking nut.
Background technique
In self-locking nut field, usually adopt elliptic or rectangular to close up and reach nut self-locking effect, large for excircle dimension, the nut of wall thickness, the size of bad control coupling mechanism force that its elliptic closes up or rectangular closes up.Especially for fluting self-locking nut, closing in distortion place is bad control especially, and when doing locking test, plug is scraped a large amount of iron filings by distortion place of nut fluting, and fluting distortion place is easily killed test plug, thus nut lost efficacy in process of the test.Therefore a kind of new-type self-locking nut of exploitation and closing method thereof is needed.
Summary of the invention
The object of this invention is to provide a kind of by axial compression screw thread self-locking nut and closing method thereof.
In order to achieve the above object, the technological scheme adopted is: a kind of axial compression screw thread self-locking nut, comprise nut twisting section and nut crimping section, described nut crimping section is provided with plural axial partition grooves, is provided with indent inside the end face of the nut crimping section between every two partition grooves; The formation of indent makes the nut inner thread generation slightly distortion be in the same way adjacent, and makes the nut crimping section at indent place slightly be out of shape to nut axis simultaneously.
Described partition grooves is six.
Described partition grooves is centrosymmetric arrangement.
The width of described partition grooves meets the nut crimping section be cut off and does not contact.
A closing method for axial compression screw thread self-locking nut, is divided into following a few step:
A, offer partition grooves, offer the centrosymmetric axial partition grooves of two or more in the closing in section of nut, partition grooves makes nut crimping section axially cut off, and is only connected with nut twisting section;
B, nut crimping section end face stamped groove, position stamped groove in the inner part in the middle part of the end face of the nut crimping section axially disconnected, the size of indent and dynamics demand fulfillment two point: the nut inner thread that one, makes indent adjacent produces and its slightly distortion in the same way, two, the nut crimping section at indent place is slightly out of shape to nut axis.
Partition grooves width in its steps A meets the nut crimping section be cut off and does not contact.
The beneficial effect of employing technique scheme is: the closing in section of self-locking nut is axially cut off by this axial compression screw thread self-locking nut and closing in mode, and stamped groove is provided with on each partition end face, the nut inner thread that makes indent adjacent produces and its slightly distortion in the same way, make the nut crimping section at indent place slightly be out of shape to nut axis simultaneously, reach the auto-lock function of nut, more traditional self-locking nut crimping mode, closing in place deformation power is convenient to grasp and control, it is easier to process, even if the thicker nut of outer wall is also by the good like this object reaching closing in self-locking, nut thread and plug bolt also can be avoided to kill phenomenon, reduce assembling difficulty or assemble the phenomenons such as not tight.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of axial compression screw thread self-locking of the present invention nut;
Fig. 2 is the A-A sectional view of Fig. 1;
In figure, 1-nut twisting section, 2-nut crimping section, 3-partition grooves, 4-indent.
Embodiment
Below in conjunction with drawings and Examples, the present invention is explained.
A kind of axial compression screw thread self-locking nut, comprise nut twisting section 1 and nut crimping section 2, described nut crimping section 2 is provided with plural axial partition grooves 3, is provided with indent 4 inside the end face of the nut crimping section 2 between every two partition grooves 3; The formation of indent 4 makes the nut inner thread generation slightly distortion be in the same way adjacent, and makes the nut crimping section 2 at indent 4 place slightly be out of shape to nut axis simultaneously.
Described partition grooves 3 is six.
Described partition grooves 3 is centrosymmetric arrangement.
The width of described partition grooves 3 meets the nut crimping section 2 be cut off and does not contact.
Above-mentioned indent 4, two effects: one, the slightly distortion of nut inner thread that produces of indent 4, be mainly manifested in the closing in end side of internal thread, when nut screws in, internal thread distortion side is interfered less with bolt thread, and installation is easy; When nut screws out, nut inner thread distortion place and bolt thread are interfered greatly, screw out frictional force and increase.Two, indent 4 makes the nut crimping section 2 at place slightly be out of shape to nut axis, and when nut screws in, nut crimping section 2 can outwards slightly be upspring, and nut inner thread and bolt snap-in force can not increase, and installs easily; When nut screws out, because nut crimping section 2 slightly bends to the inside, amount of bow can increase, and nut inner thread and bolt snap-in force also can increase, and make nut reach auto-lock function.Compared with rectangle or the oval self-locking nut crimping mode of conventional art, distortion dynamics will be caused wayward because the outer wall of nut is thicker, not easily occur that nut and bolt are killed, assemble difficulty, assemble the phenomenons such as not tight.
As the closing method of above-mentioned axial compression screw thread self-locking nut, be divided into following a few step:
A, offer partition grooves, offer the centrosymmetric axial partition grooves of two or more in the closing in section of nut, partition grooves makes nut crimping section axially cut off, and is only connected with nut twisting section;
B, nut crimping section end face stamped groove, position stamped groove in the inner part in the middle part of the end face of the nut crimping section axially disconnected, the size of indent and dynamics demand fulfillment two point: the nut inner thread that one, makes indent adjacent produces and its slightly distortion in the same way, two, the nut crimping section at indent place is slightly out of shape to nut axis.
Partition grooves width in its steps A meets the nut crimping section be cut off and does not contact.
