40% Reduction in cycle time vs. manual bolting process
3-axis Motion via pneumatic cylinders + linear rails
Approved Signed off for fabrication and production integration
Overview
  • Custom pneumatic assembly that automatically torques bolts in a live production environment
  • Designed for high cycle repeatability — eliminates operator variance across every bolt in the sequence
  • Compact envelope meeting client's integration constraints within existing tooling cell footprint
Engineering
  • Full fixture modeled in SolidWorks — pneumatic cylinders, linear rails, and a custom torque head integrated into a single assembly
  • Validated fit within full production cell assembly model before fabrication approval
  • Compact design compatible with existing tooling constraints on the shop floor
Outcome
  • Reduced cycle time by an estimated 40% and eliminated manual handling of the torque tool per cycle
  • Torque applied consistently within ±2 Nm of spec every cycle
  • Improved operator safety by removing repetitive high-torque manual operations from the workflow
  • Approved for fabrication and integration — delivered on schedule within co-op term
