Assembly Question

[Anonymous]

Hey guys. I am working on a project where I have to invent a new product with specific constraints, which you will see in the first doc., and I decided to do a candy dispenser. We have to Assemble our product and then show it in Presentation mode. However, my partner and I encountered two problems.

1. We are creating a slider to allow the candy to fall down into the capsule, (you'll see it in the Assembly file), but we don't know how to get the slider through the slot in the main connector. We don't want to Free Rotate it because we can't get it to be exact. How do we get it to be exact?

2. In Presentation mode, how do we show the tube spin to lock in place with the main connector (like a bottle cap)?

I will later on ask if anybody might be able to check my drawing files to make sure I properly baseline dimensioned. I really want to do good on this prject. You guys are my lifesavers. #The AutodeskCommunityLifeSavers

If you have any questions, please let me know. Thanks a million

First of all if you provide an assembly you need to provide all the components that are assoicated to it.  No one will be able to open your assembly.

oops. Sorry. Give me one moment

Here are the first 3 parts

Here are the remaining parts:

As I go through the parts -

classic beginner mistake in part Main Connector.  The hole for the 2-4.5 UNC is wrong size - there will not be any material for threads.

Ask your instructor about "tap-drill sizes".

Rather than use Extrude-cut and then Thread to create that hole - use the Hole feature with Threaded option.  Inventor will create the correct size hole for your thread.

In the part "Capsoules" you have an invalid fillet that goes into your Shell.  In a case like this - Inventor should return an error, but doesn't.  In the feature tree drag Fillet1 and 2 above Shell1.

In your assembly you do not have any Grounded components?

And your parts are not assembled?

Did your instructor cover the topic of assembly constraints?

Hi! I must have missed something. I am sorry to say even with the assembly files and document you provided, I still have hard time understanding what the design intent is. For the sliding behavior, I guess you can try using Transitional constraint. If you can provide a more specific example, I can show you exactly what needs to be done to make it happen.

Thanks!

So , basically, my partner and I are making it where candy is in the tube.
The slider prevents the candy from going down. We want it where, since
gravity pulls, it will pull the candy, allowing it to drop in the capsule
piece and exit out the cut door. When you pull the slider, we want the
candy to fall out. So, in assembly, we were trying to get the slider to be
aligned with the slot. I kind of got it now. But in presentation, how do I
show the tube twisting into the main connector piece lime a bottle cap? I
apologize if I still am not clear. I appreciate you helping me out however.

I can show you the next steps once you attach the new files correcting the issues I indicated earlier (with the threaded hole size and fillet anomaly).

I agree with JD that there are some more immediate and easily fixed issues that you should probably knock out first but if I'm being completely honest then I would say that I'm not so sure that this can be done in an *.ipn if that is the filetype you're trying to work in.

Are you required to use an *.ipn as well as show rotation in your presentation?

There are several ways to present a product in Inventor. If an *.ipn is not required, there may be better options available.

It can be done in ipn, but I would probably do in Environments>Inventor Studio instead, or if realistic bounce needed - in Dynamic Simulation, but that is probably overkill for a beginner.

[Anonymous]

Yeah, that would. My instructor only has Autodesk variations installed on
her computers for us. And when I have to present it, it will most likely be
on her computer.

Is there anyway you can explain to me exactly what you mean, like a
Screencast? My partner and I were confused in attempting to adjust the hole.

Inventor Studio and Dynamic Simulation is part of Inventor under the Environments tab.

I can post a video later (it is supper time here).

Ok. Thank you. For me, it's lunch time right now.

I guess I just don't use ipns enough. I typically opt for studio when given the option.

engineeringkid,

When you say you're confused about resizing the hole, do you understand why the hole is sized incorrectly in the first place? What JD is suggesting is that you have a solid cylinder there (no threaded hole nor hole at all) and then you use the "Hole" command and change the type to the threaded option and proceed to make the depth appropriate and so on. That way inventor will apply the appropriate minor diameter for the thread size.

[Anonymous]

So, why is there a hole then? I'm sorry if I seem redundant, but I am
beginner with Autodesk, and a lot of the commands I am using are new to my
instructor, who didn't learn some of these things from training.
