Activity 7.4 Assembly Models Introduction Have you ever pieced together a jigsaw puzzle? The individual puzzle pieces have to be rotated and sometimes flipped around. A piece that makes up an outside edge of the puzzle must have its flat edge flush with other pieces of that side. Pieces that have exterior protrusions must be mated to their counterpart interior recesses. The process of putting a jigsaw puzzle together is very similar to building an assembly of components in a CAD program. In this activity you will develop your knowledge of CAD assembly modeling by first practicing on a relatively simple mechanical device called a Jack Lift. This will include performing an interference analysis to determine if any unnecessary overlaps occur between the various components. Next, you will apply your skills to assemble an Automoblox toy vehicle. Equipment Engineering notebook Pencil Jack Lift CAD files: Base Wedge Wedge Screw (Optional) Automoblox CAD files: T9 Axle T9 Bed T9 Connector T9 Front T9 One Block Socket T9 Passenger Base T9 Passenger Section T9 Tire T9 Two Block Socket T9 Wheel Procedure Part I. Use the CAD modeling software to create an assembly of the Jack Lift. You will need access to the five parts of the machine: Base, Wedge, and Wedge Screw. Create a new assembly file titled Jack Lift and save it to your student folder.
