A Comprehension of Welding Positioners

For achieving optimal joint quality and accessibility during welding procedures, welding positioners are indispensable. In order to accommodate a wide range of applications, the EVS-SWP-ZW series consists of numerous models with burden capacities between 500kg and 1200kg. Integrated with an AC servo motor and RV precise reducer are the gyration main spindle case, tail case, and welding gyration frame of these positioners. Precise positioning and high gyration stability are vital for complex welding tasks and are guaranteed by this configuration. For instance, the construction of the single axis servo positioner involves the utilization of stress relief annealing on premium sections to guarantee both longevity and steadfastness. The welding positioners‘ precise motion control, which ensures accurate and stable workpiece handling with repeat positioning accuracies of up to ±0.10mm, significantly improves the performance of laser welding robots.

Positioner Integration with Laser Welding Robots

The integration of the EVS-SWP-ZW series Welding Positioners with the QJR6-2000H Laser Welding Robot produces a synergistic effect that effectively amplifies the welding procedure. This integration facilitates accurate workpiece positioning, a critical factor in attaining welds of superior quality. By coordinating the motion of the welding positioner and laser welding robot, each weld is executed at the optimal speed and in the proper alignment, thereby enhancing the welding process’s overall effectiveness and quality. Industries where production speed and repeat accuracy are of the utmost importance place a premium on this coordination.

Case Study: Manufacturing Application in Practice

An instance of this technology in action was witnessed in a project where a single robot control cabinet regulated the integration of a six-axis QJRH4-1 robot, a single-axis positioner, and a robot walking rail. In addition to conserving space, this configuration substantially enhanced efficiency. The QJRH4-1 robot, which is renowned for its dependable operation and superior weld quality, collaborated without difficulty with other machines. The versatility of laser welding robots, in conjunction with effective welding positioners, is exemplified by their compatibility with conventional welding machinery.
