Rotary tool

dejan95 · Nov 30, 2020

Hello everyone,

I'm designing a toll to check the presence of two seals on a tube like part. I will check the presence with optical camera, but I need to make the tool which will turn the tube 360° (so I will be able to check the seals on the entire rim).

I lack the engineering experience so I'm wondering what do you suggest I use? I was checking some FESTO rotating engines, pneumatics rotary tables... What are some other options?

Thank you in advance!

Given that high quality cameras cost almost nothing these days I would be inclined to use 3 or 4 cameras and not move anything for the inspection process.

I don't know how automated you need things to be but something like a rotary stage meant for laser engraving could work well. That said, multiple cameras like MJ suggests is the simplest option.

Thank you both for answering.

Control camera will also check colour, correct position (if the square seals are twisted) and so on, so the camera is really not that cheap.

@hendersdc I appreciate your idea, the only problem is that the tube is a bit larger on one side (a bit of a cone).

if it is a cone you can modify the two rollers making them with cone shape (opposite to the external shape of the pipe) or, if possible, to displace the rollers so that they are not parallel but convergent

Dejan95,

Those roller sets are meant to engrave cone shaped objects like pint glasses and baseball bats, they can be modified to work with your parts by changing the spacing on one end as robyengIT said or you could create a custom set of rollers.

Use wheels instead of rollers.

Gear motor would be cheap. You'd have to come up with a way to attach the tube to the gearbox output shaft. You might also need a support on the other end of the tube. McMaster-Carr has quite a few gearmotors:
