Four-way spherical multifunctional high-lock nut and machining method thereof

Abstract

The invention discloses a four-way spherical multifunctional high-lock nut and a machining method thereof. The four ends of a square body (4) are each provided with a nut body, each nut body is locked through pressing deformation of threads of the nut body, each nut body is provided with a neck breaking groove to be assembled, each nut body is provided with a spherical gasket used for seal, and through the mutual effect between the nut bodies and the spherical gaskets, the free rotation effect is achieved; one high-lock nut is machined, after assembly, four high-lock nuts with different specifications can be separated, the mutual effect between the nut bodies and the spherical gaskets can achieve the free rotation effect, the cost is saved, the material utilization rate is effectively controlled, safety and reliability are high, mechanical performance is stable, and maintaining is convenient. The high-lock nut is particularly suitable for being used for assembly connection of two connecting parts with the high relative position precision requirement.

Description

technical field [0001] The invention belongs to the technical field of fastener processing, in particular to a four-way spherical multifunctional high-lock nut and a processing method thereof. Background technique [0002] The main difference between the high lock nut and the ordinary nut is that the high lock nut can obtain the specified locking torque and loosening torque after installation, and it is not easy to loosen and fall off during use, which has high safety. Therefore, high lock nuts are widely used in aerospace products. Usually, the expected locking torque and loosening torque of high lock nuts are obtained through the closing process. The closing process is a process that must be carried out for high lock nuts. When the closing machine is working, the sliding tapered sleeve slides upwards vertically to the worktable surface, thereby pushing the indenter to advance horizontally to the central axis of the workpiece. When the indenter squeezes the outer circle o...

Problems solved by technology

At present, self-locking nuts have played a very important role in the connection of two parts in the aerospace field. Nearly 40% of the parts on the aircraft are high-locking nuts. In today's countries where the industrial system is gradually becoming stronger, on some parts Develop new technologies 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 current existing technologies are still not ideal
