Week 14 challenge

KIND NOTE : I have few Glitches while using Drafting with the NX software I use. I cannot click the point or face of the part. so i have drawn line and circles approximately near to the feature. I also cannot locate the exact terminating points so i have drawn lines to locate the faces. I also cannot move the geomentry i drawn. I have contacted a mentor (ankit) and he asked to mention the problem in the report. so kinly consider.

AIM: To Assemble the Butterfly valve parts and apply GD & T Symbols.

Step 1: Open the NX software and open new assembly.

Step 2: Add the components which we have modeled earlier.

Step 3: Fix the body and move all other components away.

Step 4: assemble the shaft/stem with the plate along with the bolts we created. We use align axis to axis, Distance between faces and Touch constraints to make this sub assembly.

Step 5: Align the shaft/stem to the body hole axis and use touch constraint to locate the body with the shaft

Step 6: Locate the retainer plate as such all the three holes mate with eachother and the faces are constrainded. Align axis and distance constraits are given here.

Step 7: Bolts are added to the holes which holds the body and reatiner.  Align axis and distance constraits are given here.

Step 8: Handle is placed on the retainer. we also align accordingly the key way on the stem and handle is parallel. Align axis, Parallel and distance constraits are given here.

Step 9: Nut is placed on the handle to lock it in place.  Align axis and distance constraits are given here.

Thus we finish the assmbling of the butterfly valve.

This is the extra screw bolt we created to use in the plate and shaft

This is the screw bolt we created to lock retainer and body

We then do the drafting.

A1, A2 and A3 is taken as one end of the three holes that will join the pipe. Flatness is given to it.

B and C datums are the Holes on the same faces that are located with perpendicularity and Position geomentric characteristic. Datums are taken as reference.

Body breath is controlled with profile of surface with A datum as reference.

The other side of holes are controlled with the opposite holes as datums.

And thus we done the GD & T for the Body of the butterfly valve assembly.

I have attached the files in the attachment. I have attached the all parts folder to avoid issue while doing assembly. so kindly look for Butterfly valve in it.
