Quick release mechanism electrically operated? 3

Hi there

I've come here after a heavy unlucky browsing looking for a quick release mechanism. Any hints are most welcomed, honestly I do not know where to look. It's not something complicated, but it has gave me a lot of hard time. I've searched the forum for some ideas, but nothing to fit the profile.

Basically the application involves a linear motor that needs to be coupled to an axle. The axle has at one end an compression spring. After the linear motor and the axle have been coupled, the spring is compressed.

An now it's the problem: I want to release the axle at various spring loads, so I guess a quick release mechanism electrically operated will do the job. But I haven't found any, well almost any...

The beneficiary of this mechanism will be a mobile robot, that will be more than happy to finally be able to walk or better say jump :)

The actual solution involves a quick release mechanism for hydraulic fittings (see the pic, only that it's modified a bit to need less coupling force) , but the release it's possible in just one position (where I put the limit claw that makes the coupling to be separated)

The spring will have maximum load around 40N and the coupling mechanism should be light and at most 20mm diameter.

I've tried to use an electromagnet, but for this holding force is too bulky and heavy. Honestly now I'm working at a solution that will make Frankenstein proud: to actuate the quick release in the pic with a little servo used in hobby RC servo

I find it a little odd to find all kind of solutions coupling circular moment, but very few regarding linear movement. Just point me into the right direction, 'cose for sure these days had made me crazy

Oh, it' just like a man want to buy shoes in mall: only women sandals are there :D

If you know companies that build such devices write a PM is cannot be put on the forum.


Thanks for taking the time reading this!

@waross the system is similar with the automatic center punch as zekeman was proposed?

I've uploaded one patent I've found regarding what you've said. It looks like the one you are talking about? I'm from Romania so for sure the designs could vary for those circuit breakers.

The design looks similar to this?


All the best!
