Wheel Hub Stud Insertion and Test Machine

Metaldyne required a machine to insert splined and threaded wheel studs into hubs while monitoring the force and stroke required to correctly insert the stud into the hub.

Studs are sorted in a vibratory bowl and brought to the machine via a linear slide. Once at the machine, the stud is ‘blow-piped’ into the blank hub. An Indexer rotates the hub after each stud is inserted while a precision instrument monitors the force and stroke using a LVDT and precision load cell.

An air-over-hydraulic Intensifier is utilized to produce the press forces required.
