[0002] In the field of machine tool protection, electrical control cabinets with various frame and skeleton structures are designed. Conventional technology often uses welding for rapid assembly of these frames or skeletons. However, welding has several drawbacks: first, welding deformation. High temperatures cause square tubes to twist, requiring additional correction and subsequent polishing, which is time-consuming and labor-intensive. Second, it is costly, requiring specialized welders and welding equipment, resulting in high energy consumption and low efficiency. Third, it is non-detachable. The welded frames cannot be adjusted or reused, making maintenance difficult. Existing bolted connection solutions also suffer from exposed connectors, cumbersome assembly, and weak torsional resistance. Summary of the Invention

[0003] Based on this, it is necessary to provide a processing method for detachable tooling based on mortise and tenon structure to address the problems of non-disassembly and difficult maintenance in the existing technology when frame or skeleton structures are spliced ​​by welding and screwing. The frame or skeleton structure processed by this method does not require welding and can be assembled by quick plugging and unplugging, with precise positioning, high-strength self-locking, and can be repeatedly disassembled and assembled, making it easy to transport and maintain.
