Definition & Overview

A Two-Axis Positioner is an external robot axis device used in welding, assembly, or machining processes to achieve multi-angle rotation and tilting of workpieces. Through two independently moving axes (typically a rotary axis and a tilting axis), it enables precise positioning of the workpiece in space, ensuring the weld seam or machining area is always in the optimal position.

● Core Function: Synchronized operation with robots to achieve all-position welding, suitable for complex weld seams (e.g., curves, inclined surfaces, polyhedrons).

● Typical Structure: Comprises a base, tilting mechanism, worktable, and servo drive system.

Customer Pain Points & Solutions

Structural Design & Key Technologies

1. Main Structure

● Rotary Mechanism: Uses RV reducer + AC servo motor, ensuring smooth rotation and precise positioning (accuracy ≤ ±0.1°).

● Tilting Mechanism: C-type frame supports the workpiece; rigid steel plate welded frame prevents deformation; load capacity ranges from 1 to 20 tons.

● Worktable: Surface machined with standard threaded holes (e.g., M20), supporting quick fixture installation; black oxide anti-rust treatment suits the welding environment.

2. Power & Control System

● Servo Drive: Responds to commands from the main robot controller, enabling synchronized and coordinated operation (e.g., synchronized start/stop with the welding robot).

● Current Conduction Device: Brass conduction mechanism avoids interference from welding current; equipped with quick-connect couplings for simplified utility (water/air/electric) line connection.

3. Safety Features

● Enclosed Protection: Prevents ingress of welding spatter into core components.

● Self-Locking Function: Brake motor can lock at any angle, ensuring safety under heavy loads.

Product Advantages

Efficiency Improvement

● Non-Stop Operation: Through synchronized robot control, reduces workpiece reloading time, increasing productivity by 30%-50%.

● Multi-Station Configuration: Can be expanded into a dual-station three-axis positioner, enabling parallel loading/unloading and processing operations.

Quality Assurance

● All-Position Welding: Maintains the optimal angle between the torch and weld seam, reducing defects like porosity and lack of fusion.

● Rigidity & Vibration Damping: High stiffness structure reduces vibration during tilting, avoiding welding deformation.

Cost Optimization

● Reduces Auxiliary Equipment: Replaces traditional crane flipping and manual positioning, reduces jig usage (saving 5%-15% on materials compared to traditional processes).

Summary

The Two-Axis Positioner addresses the pain point of difficult positioning for complex workpiece welding in heavy industries through coordinated dual-degree-of-freedom movement. It is particularly suitable for scenarios like ship block assembly, special-shaped steel structures in construction, and pipeline systems. Its seamless integration with robot systems provides key technical support for companies moving towards "lights-out manufacturing".
