Vertical Workholding - Welding Torque Shells

Our customer welds torque converter shells.


The requirement is for a chuck to hold torque converter hubs while rotating them in a welding machine.

The challenge

is providing a completely sealed chuck to avoid damage from excess material and additionally one that can be vertically mounted whilst maintaining constant grip during the process.

To solve this

we customized a collet chuck by adding unique top tooling. As the chuck’s inner diameter collet expands, it also acts to pull the part down and onto the outer flange. This additionally serves repeatable locating onto the datum surface.
