Design & Development of Short Benchtop Welding Positioner

Abstract

The spindle of a benchtop welding positioner is designed to meet a defined set of specifications. These particular specifications consist of dimensional optimizations for spindle height and thru bore diameter and performance requirements, such as speed. Preliminary static analyses are conducted on the subsystems with the heaviest design consideration to ensure they meet the spindle’s requirements. The design takes into account the spindle’s manufacturability, assemblability, components’ overall cost, bearing protection, grounding cable path, and more important aspects. Ultimately, a welding positioner spindle is designed, and a prototype is manufactured to investigate the outcome of the design.
