Abstract
The utility model relates to a self-lock nut. The self-lock nut comprises a nut body, a lock part, a twist-off part and a wrenching part; the twist-off part and the wrenching part are located at one end of the lock part and integrated with the lock part and the nut body; the lock part and the wrenching part are connected through the twist-off part; the lock part is located between the twist-off part and the nut body; the wrenching part is screwed to wrench the self-lock nut in place during installing and connecting, and finally the wrenching part and the twist-off part are integrally twisted off from the end part of the lock part of the self-lock nut after overall connection. According to the self-lock nut disclosed by the utility model, the lock moment of the self-lock nut is controlled by increasing wrenching force on a common self-lock nut, so hat the installation reliability is ensured and simultaneously the installation efficiency is improved.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of self-locking nut.
Background technique
In the Aero-Space industry, many structures need nut to connect, and these connection parts are had relatively high expectations to the locking torque control of nut, and large usage quantity adopts common self-locking nut installation efficiency low simultaneously, and locking torque is wayward simultaneously.Therefore the self-locking nut that needs a kind of locking torque to control connects, and guarantees locking torque in claimed range, adopts the common instrument of twisting of pulling to install simultaneously, can improve installation efficiency greatly.
The model utility content
The technical problem that the utility model will solve provides a kind of be convenient to control locking torque and self-locking nut easy for installation.
A kind of self-locking nut, this self-locking nut have nut body, locking position, twist into two parts the position, pull stubborn position; Twist into two parts the position, pull and twist the end that the position is positioned at the locking position, with locking position, nut body be one; The locking position is twisted the position and is connected through twisting into two parts the position with pulling, and locks the position and is twisting into two parts between position and the nut body;
When connection is installed, turn and pull stubborn position, self-locking nut is pulled is screwed to the position, treat that integral body connects after, will pull stubborn position at last, twist into two parts position integral body and twist into two parts from the end at the locking position of self-locking nut.
The utility model self-locking nut is twisted into two parts the locking torque of having controlled self-locking nut through on common self-locking nut, increasing to pull, and has both guaranteed installation reliability, has improved installation efficiency simultaneously again.
Description of drawings
Fig. 1 is the structural representation of the utility model self-locking nut;
Embodiment
The purpose of the utility model is; On common self-locking nut, increasing by one pulls and twists section and fuse with self-locking nut; Pull stubborn section and process outer-hexagonal, can process the self-locking nut of the locking torque of different intensity grades, guarantee that the locking torque full accuracy reaches the 0.07N.m scope through adopting different materials; Pull after the installation and twist the position, do not increase overall weight as the removal of mounting process piece.
As shown in Figure 1, this self-locking nut comprises: nut body 1, locking position 2, twist into two parts position 3, pull and twist position 4.Twist into two parts position 3, pull and twist the end that position 4 is positioned at locking position 2, with locking position 2, nut body 1 be one.Locking position 2 is twisted position 4 and is connected through twisting into two parts position 3 with pulling, and locks position 2 and is twisting into two parts between position 3 and the nut body 1.When connection is installed, turn to pull and twist position 4, self-locking nut is pulled is screwed to the position, treat that integral body connects after, will pull at last and twist position 4, twist into two parts position 3 integral body and twist into two parts from the end at the locking position 2 of self-locking nut.Twist into two parts the size at position 3, can confirm according to the size of locking torque.
This self-locking nut can be selected different materials for use as required, pulls to twist position 4 and process hexagon head, and the hole is greater than the bolt that uses, to locking torque require not too high (0.07~0.5N.m) self-locking nut, twisting into two parts position 3 can processing before heat treatment; To the self-locking nut that locking torque is had relatively high expectations, twist into two parts position 3 and can after heat treatment, process, twist into two parts position 3 size Control through adjustment and twist into two parts moment, thus the locking torque of control self-locking nut.
Compare with common self-locking nut technology, the utility model is twisted into two parts the locking torque of having controlled self-locking nut through on common self-locking nut, increasing to pull, and has both guaranteed installation reliability; Improve simultaneously installation efficiency again, setting tool is required to reduce, need not carry out Measuring and testing; Simplified working procedure; Many important connection parts are had very high application prospect, and especially Aero-Space and nuclear industry field can be widelyd popularize, and have good economic benefit and social benefit.
Claims (1)
1. self-locking nut, this self-locking nut has nut body (1), it is characterized in that: said self-locking nut also comprises: locking position (2), twist into two parts position (3), pull stubborn position (4); Saidly twist into two parts position (3), pull the end that stubborn position (4) is positioned at locking position (2), with locking position (2), nut body (1) be one; Locking position (2) with pull stubborn position (4) and be connected through twisting into two parts position (3), lock position (2) and be positioned at and twist into two parts between position (3) and the nut body (1); When connection is installed, turn and pull stubborn position (4) and self-locking nut is pulled be screwed to the position, treat that integral body connects after, twist into two parts the end of will pull stubborn position (4) at last, twisting into two parts whole locking position (2) from self-locking nut, position (3).
