Embodiment Construction

[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Embodiments of the invention: see figure 1 and figure 2 , a multifunctional self-locking nut of the present invention, comprising a nut body 1 ， The lower end of the nut body 1 is provided with an internal thread 2, and the upper end of the nut body 1 is provided with a flaring section 5. On the outer wall of the nut body 1, 6 external teeth 3 are uniformly arranged, and between adjacent external teeth 3 There is an upwardly protruding riveting surface 4, and the cross-section of the riveting surface 4 is a right triangle that gradually becomes thinner from bottom to top.

[0016] At the same time, the present invention also provides a method for making the above-mentioned multifunctional self-locking nut. In the method, firstly, the sha...

Abstract

The invention discloses a multifunctional self-locking nut and a manufacturing method thereof. The self-locking nut comprises a nut body, wherein the lower end of the nut body is provided with an internal thread; the upper end of the nut body is provided with a flared section; the outer wall of the nut body is uniformly provided with more than two external teeth; and a riveting surface which bulges upwards is arranged between every two adjacent external teeth. The flared self-locking nut changes the single locking structure of the traditional self-locking nut, implements the diversified functions of the self-locking nut, and has the functions of locking, flaring, rivet turning and rotation prevention, thereby satisfying different assembly demands and enhancing the assembly efficiency.

Description

technical field [0001] The invention relates to a multifunctional self-locking nut and a manufacturing method thereof, belonging to the technical field of standard part manufacturing. Background technique [0002] At present, self-locking nuts have played a very important role in the aerospace field, and nearly 40% of the parts on the aircraft are self-locking nuts. In countries where the industrial system is gradually becoming stronger today, new technologies are developed on certain parts, so that one part can have multiple functions at the same time, which not only saves production costs, but also effectively controls the weight. However, the existing self-locking nuts only have a self-locking function. When assembling parts, sometimes the self-locking nuts are required to have the functions of flaring, riveting and anti-rotation to meet different assembly requirements. Contents of the invention [0003] The object of the present invention is to provide a multifunction...
