Turbo Installation Manipulator Final Design Review Sponsor: Brent E. Nelson with Caterpillar Inc. Faculty Advisor: Dr. Casey Smith

Project Overview Currently, the system involves interchangeable pucks. The main goal of our project is to make sure the wrong puck cannot be installed. To do this we have designed a one size fits all device to replace the pucks. State the problem and the project in clear terms. Use a graphic if at all possible.

Project Motivation The problem: Pucks do not have a footprint or designated area Each puck is sized to only a few turbo part numbers If no stretch goals then delete the text box on the right, and expand the one on the left. DO NOT ELABORATE ON THE GOALS, JUST STATE THEM QUICKLY AND MOVE ON!!!

Top-Level Block Diagram Engine arrives at work station Team member uses GCI arm to lift the turbo Team member moves turbo to the engine Turbo is attached to engine and released from arm. Put in a readable top-level block diagram to show what your project does and how it fits in to the system.

Design-Level Block Diagram Swing Arm closed and pressure plate depressed Moves GCI arm to turbo Gripper is expanded pneumatically Put in a block diagram – or flow chart – of your design. Highlight in yellow the blocks that the team will be designing. Turbo is moved to the engine and installed GCI arm is moved back to the home Release the turbo

Results Air bladder design was dropped and a new mechanical linear actuator gripper was designed and prototyped Air logic was incorporated with PLC logic Concisely state the feature/approach changes made since the Initial Design Review. Keep it a minute or less.

Results Cont. Prototype provides proof of concept (Adjustable to all diameter ranges) Max Diameter of Turbos: 137mm Min Diameter of Turbos : 65mm Max Diameter of Gripper: 148mm Min Diameter of Gripper: 62mm Fits depth of all turbos: 10-25mm Insert a tabular form of Section 4.1 from the Characterization Report.

Future Work Changes Reasoning Use of nuts, bolts, and sleeves to hold the elements of the gripper together. This would make the device more stable and reliable Prototype design using a metal or high strength material Prototype would be a proof of concept using a new manufacturing method. Modify particular dimensions of gripper for manufacturing into a new material This would need to be done in order to satisfy metal manufacturing which is completed using a different process as well as strength of material Move the holes in which the nuts and bolts will be inserted, farther away from any edges Allow for less force to be exerted towards breaking points. Design a pressure plate Plate would control a sensor that would not expand until gripper is a minimum distance inside the turbo Insert a tabular form of Section 4.3 from the Characterization Report.
