Coupling for Samsung CP40 nozzle holder to NEMA 8 motor

[Lance Endres]

The conversations about the history of Juki versus Samsung nozzle adaptors have me thinking about using the CP40 Samsung nozzle adaptor on a NEMA 8 motor.

My friend and I have been discussing this and we came up with a basic coupling design.  We want to manufacture a couple and test them, but before we do that we'd like feedback from the community.

The idea is based on the pneumatic coupling that came with the pre-assembled head unit I bought.  The coupling has a slip fit for the NEMA 8 motor and an M5 on the other side; which is exactly what the CP40 nozzle adaptor needs.  There is an o-ring that sits between the faces of the motor and the pneumatic connector to seal create a seal.

We would lengthen the coupling as much as possible and tighten tolerances to get more accuracy.  The drawings are below.

We'd really appreciate any feedback/advice on having these manufactured.  I think our biggest concern is the tolerances on the nozzle slip/press fit on the motor side.

General comments would also be welcome.  Would there be interest in these couplings?  Does this seem like a reasonable approach?  Et cetera.

Thanks,

Lance
