Automatic Welding Fixture for Special Purpose Mechanism

Abstract: In recent times, manufacturing industries have increasingly prioritized automation to enhance efficiency and precision. This project focuses on designing a fixture for a rotary welding machine using a Special Purpose Machine (SPM) to improve accuracy and productivity in mass production. The fixture is specifically designed to secure components while performing rotary welding of a circular rod over a lever. Maintaining high accuracy in manual welding processes is challenging, particularly in mass production. This project addresses that challenge by introducing a new fixture design that ensures precise angular positioning and rotary movement, achieving an accuracy of 0.1 mm—all without the use of robotic automation. In the field of welding engineering, where high-quality, cost-effective production with maximum efficiency is crucial, this fixture-based approach offers a reliable, scalable, and economical alternative to robotic welding systems. The proposed design ensures consistent weld quality while reducing manual errors, making it an ideal solution for industrial welding applications
