Improvements to a Welding Manipulator

• Client & Funding: Wendland Manufacturing Corporation, San Angelo, TX
• Student: Lindsay Barnes, Alan Backlund, Joseph Gomez
• Duration: Fall 2020 - SP 2021 (MENG 4279 and MENG 4380 ME Senior Design I and II)

Abstract:
As part of the new Mechanical Engineering program at Angelo State University, senior-level capstone students partnered with Wendland Manufacturing, to develop a new concept design to improve upon the existing design of a custom-built pressure vessel welder manipulator located at their production facility. Two main problems were presented by the client related to the existing design. The first problem was related to the safety of the operator and bystanders while the machine is in use. The second problem was related to the need for physical manipulation of the machine by the operator. The existing design presented multiple inefficiencies that could be addressed by developing new design solutions. These solutions were focused on adding mechanical systems to improve the raising and lowering movements as well as the rotational movements of the machine. Each design solution integrated new safety measures aimed at preventing injury to not only the operator but also the machine itself. Utilizing mechanical, structural, electrical, and industrial engineering theory, concept solutions are proposed that meet the requirements set forth by the client. Gearmotors, sprockets, roller chains were determined to be the best solution for handling the movement of the machine. Limit switches and a safety latch mechanism using shock absorbers were determined to be the best solutions to improving the safety of the machine and the operator. BGB Mechanical developed the proposed solutions with the help of Angelo State University faculty, industry professionals at Wendland Manufacturing and Indeco Industrial Electric, as well as help from other students at Angelo State University.
