Need help with mechanical joints

ChroniC · 20 Jun 2017 at 11:24

I want to build a prototype idea I have for a very minimal cost, so am scrowing the internet for existing objects I can bodge together just to see if it works.

I need a joint or a combination of two working parts. As shown in the diagram it needs to have this ability.

I believe I can get the 180 degree movement with this joint, although there maybe be a better options (hence me asking)

However I would need to fix this to a swivel plate of some kind to then allow it to rotate 360°

Does anyone know of anything that combines these two things or the names of these particular joints and where I can go get them. Thanks

Dont know what going on with the images can't seem to embed them at all. Weird.

Is this what you're after?

Edit: Actually, it's not as it is, but if you then add something where it connects, and pivot that from the connections, then it should achieve what you're after. Or something similar at least!

Yes and no. It might end up with a small load on the joint so not sure how that would handle it.

That would do the job but it's a little small. I am looking at something like this

Just wondering if there is something a little tidier that could be had from somewhere like B&Q/Screwfix etc, I can't weld and I don't know how I'm going to fix these things together.

either the above or a pivot joint on a rotary bearing ?

Some sort of ball joint might work. Possibly too small range of movement though.

You could even make your own quite easily:

I was initially going with the ball joint route but could not find any with a range above about 45°. Your image might work but it needs to be free moving and I see that being quite rough.
Thanks though.

What's it for? going to have to hold?

It's not going to hold anything. It's for a device that will have a user rotate it, so will have some tension applied to it, but hopefully not to much.

If you want a fidget spinner just buy one you pleb

Trust me the actual useage, I have an entire store full of bits & bobs, I might be able to find something.

Ok What I am thinking now of doing is this.
M12 rod either side of this universal angle joint.

Connected into a 12mm bore rotary bearing. (Thanks Loam)

Is this for some sort of pleasure device??

ChroniC · 20 Jun 2017 at 15:30

No, but if it works and I become a millionaire inventor, maybe I'll make you a sexbot next.

I am such a loser because when I read the thread, I thought of something else

I thought the same.
