Week 14 challenge

After the design, all the models should assemble with appropriate constraints. The assembly is created by first placing the body in position and mating other parts to it with the application of different joints provided in NX. First, the shaft and disc are joined together with the screws in place to create a sub-assembly which is then joined to the body in position. The retainer plate is then mated with the body and screws are used to fix them. After that, the lever is mated to the shaft in a position that is then fixed after the nut is mated with the shaft.

Features used to Assembly:

• Infer Axis/center

• Touch Align

• Concentric

• Move Component

Methodology:

The Assembly file is opened in NX CAD.

The above parts are added to the assembly file.

Now, one by one part is assembled using the Move part command and assembly constraint command.

Different constraints are used to assemble butterfly valve, such constraints are Infer Axis, Touch, Align.

Finally, the assembly of the butterfly valve is saved in the folder where all the other parts are saved.
