The workstation is equipped with a seventh-axis linear traveling rail driven by high-precision rack and pinion transmission, which effectively extends the effective working radius of the robot. It fully covers all welding stations including ultra-long frame welds of machine tool beds, fillet welds of dense reinforcing ribs, and load-bearing splicing welds of bases. The equipment features smooth start-stop operation and high repetitive positioning accuracy. During the welding process, it can linkage with the robot body to fine-tune the welding posture in real time, always maintaining the optimal welding angle of the welding torch, and laying a solid foundation for the forming of large component welding from the hardware level. Compared with conventional fixed-station welding equipment, it eliminates the need for repeated workpiece moving and multiple fixture position adjustments, adapting to non-standard welding processing requirements of machine tool beds of various specifications, with greatly improved versatility and adaptability.

The core highlight of this demonstration is the standard intelligent teaching-free welding system. It frees operators from manually recording welding trajectories point by point, repeatedly debugging welding positions, and reprogramming and teaching for different batches of machine tool bed workpieces. It subverts the traditional robot welding operation mode that relies on professional programming technicians, time-consuming teaching and low efficiency of product changeover and debugging. Relying on intelligent visual recognition and automatic weld seam sensing technology, the equipment can independently scan and identify the outline of machine tool bed workpieces, accurately locate various weld seams to be welded, automatically match process parameters suitable for thick plate welding, and independently plan the optimal welding motion trajectory. Welding operations can be started directly after power-on, truly realizing immediate welding after loading, teaching-free operation and one-click welding execution.

During the welding operation, the seventh-axis ground rail operates in coordinated linkage and synchronous motion with the welding robot, achieving continuous and uninterrupted automatic welding throughout the whole process. Combined with real-time weld tracking and adaptive adjustment of welding parameters, it precisely controls welding heat input, ensuring uniform and qualified weld penetration as well as smooth and full weld bead formation. It reduces common welding defects such as welding deformation, porosity and slag inclusion of machine tool beds from the source, strictly guarantees the core structural rigidity and overall dimensional accuracy of machine tool beds, and meets the stringent production standards of high precision and high stability for machine tool equipment. The entire welding process requires no full-time manual on-duty intervention, which greatly lowers the threshold of manual operation and labor costs, and significantly shortens the product changeover and debugging time. It is suitable not only for mass standardized production welding of machine tool beds, but also for multi-variety and small-batch non-standard customized welding processing scenarios.

The entire demonstration intuitively presents the in-depth integration advantages of DELAMPS's seventh-axis traveling mechanism and teaching-free intelligent welding technology, fully demonstrating the enterprise's strong strength in providing hardcore solutions for automatic welding of heavy mechanical structural parts and core large machine tool components. With an intelligent, simplified and efficient welding mode, it helps manufacturing enterprises reduce costs, increase efficiency, improve quality and speed up production, and realize the intelligent upgrading and transformation of the welding process for machine tool beds.
