Part to be crushed in Assembly

Hi there!

So I am working on a part that comes in like the picture with the black background, but in the actual assembly process, the part is crushed on the bottom end to hold another part in place see the picture with the model of it crushed. I am looking for any tips or advice that will let get out of having a model of how it purchased and another being crushed, or the crushed having a bill of material of the purchased part. Thanks

How about using Simplify Part to create the other state of the model?

Adjustable Part may possible as well.

As long as the rivet is rolled the same way in every hole and every assembly it is applied, then the simplified part would work.

 

Combining simplified part with adjustable part (to allow for varying throat lengths) may allow for different clamp lengths of the rivet, but the rolled end will still be exactly the same, which is not perfectly accurate, but may be good enough.

 

A drawing of the rivet can be shown as designed or as simplified, so any drawing view can be adjusted to display the correct version, but that will take a lot of manual intervention to keep up-to-date.  Display configurations could help.

 

Using the Simplified representation as a "poor man's" part configuration could be a workable solution.  But, I anticipate a lot of difficulty in making sure the correct version is being shown at the correct place when multiple simplified parts are used.

Thanks! The Simplified part works perfectly for this.

We only usually use the pre-installed version, and accept that it possibly looks odd in a drawing.

Messing around with adjustable parts for things like rivets is really not worth the effort (and they don't pattern as the original). Many of these are blind fasteners so we need to know there is sufficient clearance behind for fitting.

 

We do use adjustable parts for some things like jubilee clips.

We create a mess.

 

For every soft good, we have the as-purchased version that defines the nominal product and is used on the drawing for the item.  The filename will be the item number and revision (ex. P1-1^A.par, where P1 is the base number, -1 is the configuration, and ^A is the revision)

 

When that soft good is used in an assembly (let's say assembly A1, whose filename is A1-1^A.asm), we include the P1-1 part, usually grounded to the origin, then hide it.

 

Next, we create an as-designed version of that soft good.  It's filename is A1-P1-1^A.par.  In other words, the assembly the part is used on (unique to), followed by the actual part number, and revision.

 

The trick to the whole system, besides the PITA to manage all these links: OCCURENCE PROPERTIES.

We could very easily ignore this hassle and only insert the as-designed version into the assembly, with its unique filename.  In the file properties, we would simply call out the as-purchased part number (and other information).  The drawback of doing that is then we don't get a complete "where used" on the actual purchased part since only the as-designed file would be referenced in assemblies.

The Simplified part works perfectly for us since the rivet is crushed to the same dimension every time. Pic Rivet1 is our purchased part placed into an assembly and what we keep up to date with its own drawing. Pic Rivet2 is when we convert it to the simplified part after it has been placed.
