Space buttons are integral components in large-scale construction projects, often requiring precise machining. While CNC milling machines offer high accuracy, their significant investment cost can limit their economic viability for all production scenarios. This paper addresses the critical need for a cost-effective alternative by focusing on the design and fabrication of a specialized jig for processing these space buttons on readily available universal vertical milling machines. Such an innovation is crucial for maximizing the utility of existing machinery, ensuring the required technical accuracy of components, and ultimately enhancing production efficiency and adherence to schedules. The inherent complexity of machining space buttons, which demands processing at multiple angles, underscores the necessity for a jig capable of complex, synchronized movements.

Engineers, researchers, and students in mechanical engineering, manufacturing technology, and industrial design fields, particularly those specializing in jig and fixture design, machining processes, and production optimization.

This paper meticulously presents the calculation and comprehensive design of a specialized jig developed for processing space buttons on a universal vertical milling machine. The research method involved several key stages: firstly, detailed calculations and rigorous durability tests were conducted for critical sub-assemblies, including rotating mechanisms, indexing devices, and auxiliary clamping systems. Following this, the structural design of these components was meticulously outlined. A crucial aspect of this study was the application of Inventor software, not only for simulating the operational process during the jig's machining phase but also for visualizing the entire jig assembly. The findings confirm the successful development of a robust and effective jig structure, complete with precise component design and assembly procedures, validated through sophisticated simulation. This work offers a practical and economically viable solution for manufacturers, enabling them to produce complex space button components with high precision by fully utilizing existing universal machine infrastructure. The jig's design specifically addresses the challenge of multi-angle machining, which is essential for space buttons. Furthermore, the study identifies avenues for future enhancements, focusing on improving the overall rigidity and machining accuracy of the jig system, alongside establishing comprehensive maintenance protocols to ensure long-term performance and reliability.
