Abstract
The invention discloses a light thin-wall lining plate self-locking nut assembly and a manufacturing method thereof. The nut assembly comprises a lining plate and a riveting shaft nut, the lining plate is provided with a riveting hole allowing the riveting shaft nut to penetrate through, the riveting shaft nut comprises a body and a threaded hole formed in the body, and the threaded hole and the body are coaxial. A step-shaped punching and riveting part is arranged on the periphery of one end of the body, a closing-up part is arranged on the periphery of the other end of the main body, the closing-up part is riveted in the riveting hole, the diameter of the closing-up part is smaller than that of the punching and riveting part, and a connecting part is arranged between the closing-up part and the punching and riveting part; and the connecting part is used for smooth connection between the closing-up part and the punching and riveting part. The manufacturing method of the nut assembly comprises the following steps that firstly, the rivet shaft nut is machined; secondly, the lining plate is machined; and thirdly, assembling is conducted. The light thin-wall lining plate self-locking nut assembly meets the specified thrust requirement, the closing-up part is stable, installation is reliable, and bending can be avoided.
Description
technical field [0001] The invention belongs to the technical field of mechanical component manufacturing, in particular to a light-duty thin-wall liner self-locking nut assembly and a manufacturing method thereof. Background technique [0002] The mechanical connection method of this kind of light-weight thin-walled liner self-locking nut is used to connect some important parts in various aircrafts, ships and some civil aviation. There are specified requirements. In particular, the riveting shaft nut cannot be deformed when it is installed in the thin-walled liner, and the verticality after assembly is 0.1mm. Next, a push-off test is required to ensure that the unscrewing torque is not less than 3N mm, and the riveting shaft nut cannot fall off the thin-walled liner under 450N. liner. The existing rivet nuts cannot meet the above requirements, so it is urgent to design a new rivet nut structure. Contents of the invention [0003] The present invention intends to provid...
