Embodiment 1

[0066] Such as figure 1 , image 3 , Figure 5 with Figure 8 As shown, the lock nut includes a nut body 1 and a washer 2. The washer 2 is movably connected to the nut body 1. The lock nut also includes a locking ring 3 that is an opening. The screw shaft passes through the locking ring 3 and is locked. The ring 3 is connected with the lock nut, and the inner size of the locking ring 3 can be enlarged or reduced after being subjected to an external force. The nut body 1 has internal threads and is threaded on the screw shaft. The bottom of the nut body has a bent stop 1a. The stop 1a is used to limit the axial movement of the washer 2. The washer 2 can realize circumferential rotation. The nut body After 1 and washer 2 are installed to the preset position of the screw shaft, clamp the lock ring 3 with the clamping device until the lock ring 3 fits firmly with the screw shaft and tightens the lock ring 3 to the screw shaft. Realize the overall anti-loosening function of the ant...

Embodiment 2

[0075] Such as figure 1 , image 3 , Image 6 with Figure 8 As shown, the difference between this embodiment and the first embodiment is: the locking ring 3 is connected to the washer 2, the top of the washer 2 is the connecting portion 2b, the bottom of the washer 2 is connected to the locking ring 3 and a deformation gap is formed between the two 4. The gasket 2 has an opening structure and the opening position is the same as the locking ring 3. In this solution, the washer 2 and the locking ring 3 are both open structures, and the limiting portion 1a on the nut body 1 is formed first, and then the inner diameter of the washer 2 is expanded through the opening 2a structure of the washer so that the connecting portion 2b is sleeved in the limiting On the position 1a, the mouth can be closed at the end. This solution does not require punching and is easy to process.

[0076] The assembly method of the lock nut component in the above scheme includes the following steps:

[0077] ...

Embodiment 3

[0081] Such as figure 2 , Figure 4 , Figure 7 with Figure 8 As shown, the difference between this embodiment and the first embodiment is that the locking ring 3 is located on the nut body 1, an extension portion 1b extends from the top of the nut body 1, and the bottom end of the extension portion 1b is integrated with the nut body 1, and the extension portion 1b The top end is connected with the locking ring 3 and a deformation gap 4 is formed between the two. In this solution, similarly, the extension portion 1b and the locking ring 3 are connected by a connecting section 5, and the locking ring 3 can be obtained by processing the extension portion 1b. This solution allows the washer 2 to maintain the traditional structure, and is improved on the self-contained structural extension 1b of the traditional locknut, making full use of the existing structure to achieve corresponding functions.

Abstract

The invention provides a locknut and a using method thereof as well as a part assembling method, and belongs to the field of machinery. The locknut comprises a nut body and a gasket, and the gasket ismovably connected with the nut body; the locknut further comprises a locking ring with an opening; and a screw shaft penetrates through the locking ring, so that the locking ring is connected with the locknut, and the internal size of the locking ring becomes larger or smaller after the locking ring is subjected to external force. The locknut is beneficial to subsequent disassembly and protectionof the screw shaft. The using method of the locknut comprises the steps of pre-mounting, clamping and dismounting, any violent dismounting step does not exist by clamping and pulling the locking ring, and the screw shaft is fully protected. The part assembling method comprises the steps of flaring sleeving and necking closing, the design is novel, the yield is high, and processing is convenient.

Description

Technical field [0001] The invention belongs to the field of machinery, and relates to a lock nut, a method of use thereof, and a method of assembling components. Background technique [0002] Locknuts are widely used in the field of automobile fastening and mechanical fastening. Its fundamental function is to enhance the axial limiting force when the nut is tightened and prevent the nut from axial loosening. At present, there are many types of locknuts and more combined types. Is universal. [0003] For example, the application number is 2018201266082, the application date is 2018.1.25, and the name is a utility model patent for a locknut and threaded connection, which records a locknut, including a nut body, and the nut body is threaded to connect bolts and bolts. The thread section is provided with a groove along the axial direction, and the end of the nut body is also provided with an extension section. The extension section has a hollow cylindrical structure. The nut body and...
