3. Structural Design and Technical Features
3.1 High-Rigidity Structure for Stable Operation
The single-axis travel rail adopts a welded structure made of high-quality profiles and steel plates. After professional heat treatment, precision machining, and subsequent surface processing, the system ensures excellent rigidity, long-term stability, and durability under continuous operation and heavy-load conditions.
The surface is coated with anti-rust primer and industrial paint, providing both corrosion resistance and a clean, professional appearance suitable for industrial environments.
3.2 Precision Servo Drive System with High Positioning Accuracy
The drive system consists of an AC servo motor combined with a precision planetary gearbox. Power is transmitted through high-precision helical rack and pinion gears, while motion guidance is ensured by high-quality linear guide rails and matching sliders.
This configuration guarantees smooth motion and accurate positioning, achieving a repeat positioning accuracy of ±0.10 mm, which fully meets the stringent requirements of high-quality welding processes.
3.3 Automatic Lubrication System for Reduced Maintenance
The travel rail is equipped with an automatic lubrication system, which periodically supplies lubricant to the linear guide rails and rack-and-pinion components. This effectively reduces wear, extends service life, and significantly lowers routine maintenance frequency and cost.
3.4 Semi-Enclosed Protective Design
A sheet-metal bent protective cover with powder-coated surface is adopted. The cover is robust, resistant to deformation, and effectively protects the internal motion components from welding spatter and dust, while maintaining a neat and industrial-grade appearance.
