Description

technical field [0001] The invention relates to the technical field of nut manufacturing, in particular to a production line for hexagon lock nuts with positionable inserts. Background technique [0002] A nut is a mechanical part that has an internal thread and is used in conjunction with a screw to transmit motion or power. In component assembly, bolts and nuts are usually used to fix the two components together. The anti-loosening of nuts during the long-term use of components has always been an important research topic for threaded connections. [0003] Insert slotted self-locking lock nut is a kind of fastener with high anti-vibration and anti-loosening, which can be used in various machine and electrical components in the fields of aviation, spaceflight, and machinery with an operating temperature of -50°C to 100°C. The working principle of locking is as follows: during the installation process of the thread pair, the thread of the bolt squeezes the insert embedded i...

AI Technical Summary

Problems solved by technology

It is difficult to ensure that the feeding speed and the pressing speed of the insert nut pressing device maintain accurate stepping motion by manually loading the insert, which affects the production efficiency of the insert pressing

At the same time, when the insert is manually loaded, the position of the insert will inevitably produce errors; after the insert is manually loaded, the position of the insert will also move when it is placed in the insert nut pressing device, all of which will affect the insert Production quality of installation

[0005] The traditional manual installation method will not only affect the pressing quality of the inserts by artificial factors, but also make it difficult for the insert nut pressing device to press the nut and the insert to the specified state when the insertion position is unqualified

Moreover, manual feeding requires a lot of manpower, equipment and space. Compared with mechanical automatic feeding, the production efficiency is low and the production cost is increased.
