Jig & fixture for automotive part assembly

The old fixture did not locate the part repeatably, so weld positions drifted and parts had to be reworked. Scrap was highest at the start of a shift, before the machine had warmed up.

• Measured real parts and traced the drift back to specific clamping points before redesigning anything
• Designed five locating points with pneumatic clamps, shaped so the part cannot be loaded the wrong way round
• CNC machined with ±0.02 mm control at the datum features
• Every set inspected before shipping, with a dimensional report against the drawing

• Weld positions now repeat on every part, cutting rework
• New operators are productive immediately because the part physically cannot be loaded incorrectly
• The dimensional report serves as evidence at incoming inspection
