BOLT ASSEMBLY REDUCTION

This disclosure relates to inserting bolts which are bigger than the hole they are meant to be fitted in (interference fit). 

Shrinking a bolt before it is to be fitted will reduce any:

·         Damage to the hole and bolt surface as the bolt is dragged into the hole, whether pulled or knocked in. 

·         Insertion into the hole without creating any excessive noise, from example from a rivet gun.

·         A reduction in present PPE wearing lower ear protection and no anti-vibration gloves.   

·         Reduction in compressed air usage.

·         Reduction in damage to the panel from the rivet guns.

The diameter of the interference bolts may be reduced using the likes of liquid nitrogen or gas nitrogen in a controlled unit. 

Firstly with the bolt being reduced in diameter, there would be less friction inserting it through the previously drilled hole, thereby reducing noise levels and HAVS through using rivet guns, which can also lead to damage of the face of the product. 

There are currently on the market screw/bolt/nail feeder guns, such as nail guns, and if such a machine can feed a bolt from a cartridge with either gas nitrogen or liquid nitrogen reducing the diameter of the bolt as or before the bolt is fed, the bolt could be inserted fully, straight up to the head without noise or effort. 

By having a sealed cartridge containing liquid nitrogen or gas nitrogen packaged with the gun magazine, during a production process, interference bolts can be exposed to the liquid ...
