C Type Two Axis Servo Welding Positioner for Accurate Workpiece Manipulation
Overview
The C Type Two Axis Servo Welding Positioner for Accurate Workpiece Manipulation is a servo-driven positioning device designed to provide stable, controlled, and precise workpiece orientation for welding applications. Featuring an open C-type structure and dual-axis rotation, this positioner allows weld seams to remain in optimal positions throughout the welding process, improving welding quality, consistency, and production efficiency. It is suitable for both manual welding stations and robotic welding cells.
Key Features
lOpen C-type structure for easy loading and excellent accessibility
lTwo-axis servo-driven rotation for controlled workpiece positioning
lSmooth and stable motion with RV precision reducer
lReliable conductive system designed for welding applications
lPLC-based electrical control for stable and long-term operation


Structure and Mechanical Design
The positioner is built on a welded integral frame made of high-quality structural steel profiles. After welding, the frame undergoes stress-relief annealing followed by precision machining, ensuring high dimensional accuracy and long-term stability at critical load-bearing and installation positions. The frame surface is finished with anti-corrosion industrial paint, providing durability and a clean appearance. Frame color can be customized according to customer requirements.
The welding positioning frame is fabricated from premium structural steel sections and precision-machined after welding. Standard threaded mounting holes are provided on the surface to facilitate the installation of fixtures and tooling. The positioning frame is treated with painting and black oxide anti-rust processes to enhance corrosion resistance and extend service life.
Dual-Axis Servo Drive System
The C Type Two Axis Servo Welding Positioner adopts AC servo motors combined with RV precision reducers as its drive system. This configuration ensures smooth rotation, accurate positioning, and stable operation during welding processes.
The dual-axis design enables flexible workpiece manipulation:
lAxis 1 provides controlled tilting of the workpiece
lAxis 2 offers continuous 360° rotation for circumferential and complex weld seams
This reduces manual repositioning, improves weld consistency, and supports automated welding operations.

Conductive and Electrical Control System
A brass conductive mechanism ensures reliable current transmission during welding. The conductive base features a fully insulated design, effectively protecting servo motors, welding robots, and welding power sources from electrical interference or potential damage, enhancing operational safety and system reliability.
The electrical control system is based on a Japanese OMRON PLC, delivering stable performance and low failure rates. All electrical components are selected from well-known domestic and international brands to ensure long-term reliability and consistent operation.
