Therefore, they are designed with high-rigidity bases, precision bearing systems, robust servo drives, and reliable protective structures to ensure positioning accuracy, repeatability, and long service life.

These positioners are widely used in various welding automation applications including long or medium-to-large weldments, light-duty welding lines, electric vehicle welding and assembly positioning, large steel structures, and construction machinery.

Heavy-duty welded steel structures are used as the main frame for single axis rotary positioners.

Structure of a Single Axis Rotary Positioner

A typical single axis rotary positioner consists of several key components:

• High-precision servo rotary drive system
• Heavy-duty precision bearing system
• Worktable (rectangular or circular)
• High-rigidity base structure
• Robot external axis interface
• Control system with position feedback
