    Spring Clip Compression

    Don Cheke

      I have a V-shaped spring clip that is placed between two sheets of glass that compresses to a U-shape. Is it possoible to use mates to compression the spring clip?

          Hello Don,

           

          I'm at home now and don't have SW here so I can't post an example, but I'll try to explain it.

           

          Assuming that the spring is modeled from a U or V-shaped extrude, I would place a construction line in the sketch connecting the ends of the straight sections (where it will contact the glass).  Constrain one end of this construction line but leave the other end un-constrained, and constrain the rest of the sketch so that when you drag the un-constrained end the sketch will move as desired.

           

          When you insert the spring into your assembly, mate the fixed end of the construction line to the glass and place other mates as needed to keep the spring from rotating.  Next, edit the spring within the assembly and make a coincident relation between the end of the construction line and the other piece of glass.  The spring may not move dynamically with the glass but it should update when you rebuild the assembly.

           

          While I'm writing this it occurs to me that it might work better to have the construction line as a seperate sketch in the part, with the sketch for the extrude below it in the tree and restrained to it, but I realy don't know which would work better.

           

          Good luck,

          Glenn

            Here is one example. You can also model the spring as seperate part and then add in context relation to it with the two side plate.

              Don,

               

              Did you get it to work?  Here is my example.  It's very similar to Deepak's, except my spring is a seperate part and his is virtual, and I did mine with SW2012.

                Thanks Glenn & Deepak for the help on this. Very much appreciated!
