Mechanism to lock two parts together

Anonymous — Mon, 09 Apr 2018 20:04:13 GMT

Hi everyone,

I am trying to lock two different boards so they are stuck as one piece but can be removed later. I am trying to make a sort of slide and lock mechanism between them but I haven't been able to make anything successful that works.

If anyone has any experience with this kind of problem or any ideas, I would appreciate it.

Thanks,

Daniel Wong

IMHO the best way to do this, is to use components and Assemble -> Join them. Using components is a good practice anyway (Rule #1).

I've created a simplified version of your design and you can see the join in the screencast.

If this doesn't fit to your problem you might want to share your design here.

I've missed to attach the sample project... stupid me 😉

Thanks for your input! Not quite what I was looking for, but it helped.

Think I'm going to mess around a bit more.

Regards,

You're welcome. If this is not exactly what your are looking for, what are you looking for?

My concern is that the two parts wont be locked in secure. I want to be
able to just pick up one side when they are interlocked and not worry about
it coming undone. I was hoping to constrain it multiple planes if that
makes sense.

Are you talking about a real world "pick up" or within fusion?

A Rigid Joint will lock two components together and maintain the relationship.

See if any of the joints in the attached will work for you!
Cheers

I am talking about in real world terms. I will be trying to print it out
and connecting them and the result hopefully, will be that they will be
pretty interlocked so that it doesn't come apart too easily.

I will be printing out with a CR10 3D printer. If that helps

thanks ive never seen this chart before. I will take a look at this and see if something here will work

@Anonymous: Those digital joints are IMHO more related to woodworking and CNC. I would guess, that you could getaway with dovetails more or less all the time.

@Anonymous: Another phrase than joint might be "3d printing snap fit design" you can google

@lichtzeichenanlage

I like the simple dovetail but it doesn't have vertical retention. So in order to meet the 'pick-up' requirement it would need glue of some kind. That's where the more complex solution comes in. Specifically I would consider the shouldered dovetail or double jigsaw to provide locking and vertical support. I haven't used these joints so a quick prototype would be in order to confirm. Thanks for linking to the higher res image. I was on my phone on the bus and...well...you know, it wasn't optimal. Opening up the design space a little more there are other options galore. Hinge type joint with a simple rod to tie the two together. Plastic cantilever/annular snap fit. I don't know how thick the two parts are but you could stake in a knurled threaded insert on one panel and use flush head fasteners to tie the two together.

Okay thanks for the help,

I am 3D printing a test piece to see if it will hold and will post my results when it is finished.

I would have liked to glued or just make it a single part but we wanted to make it so it could be in two parts that could be assembled and disassembled quickly.
