Background
Factories are enhancing their assembly areas with handheld pulse tools to boost productivity. When used correctly, these tools offer ergonomic benefits, high tightening speeds, and reliability in manufacturing. Pulse tools combine the advantages of impact wrenches – they are nearly reaction-free, very fast, and easy to operate with one hand. Additionally, they provide high accuracy and significantly reduce noise and vibrations. However, in manufacturing, pulse tools are often used with an extension (placed between the tool's output and the socket) due to limited access to the threaded fastener joint. The installed torque may vary when using an extension, compared to the predetermined torque set on the tool. This thesis aims to gain a deeper understanding of the loss in pulse energy when using extensions of different lengths on a threaded fastener joint. This knowledge will help develop tightening strategies that compensate for these losses, ensuring better quality of the threaded fastener joint during manufacturing.
Objective
Investigate the impact of using extensions of different lengths on the installed torque and clamp force of a threaded fastener joint when tightened with a pulse tool at various power settings.
Methodology
Conduct experiments to collect and analyze data on the tightening process. This involves using a pulse tool with extensions of varying lengths to tighten different threaded fastener joints. Perform an in-depth analysis of the gathered data to understand the effects of extension length on the tightening outcomes.
