PDKJ Three-Axis Platform Laser Welding Machine for Fan Blades

▷ Application Industry: Cooling Fan Manufacturing

▷ Workpiece: Fan Impellers / Fan Blades

In cooling fan manufacturing, the quality of the connection between fan blades and the rotor core is an important consideration in the welding process. For workpieces with specific structural features and welding position requirements, equipment design must account for workpiece positioning, welding trajectories, and production operations.

This case features the PDKJ Three-Axis Platform Laser Welding Machine for Fan Blades, developed and manufactured by PDKJ. Using a 1500 W laser welding system, the machine integrates three-axis motion control, positioning fixtures, and a rotary clamping mechanism to provide a customized welding solution for joining fan blades to rotor cores.

1. Project Background

This project was developed for the cooling fan manufacturing industry to address the welding requirements for connecting fan blades to rotor cores.

These workpieces have specific structural and assembly characteristics. During welding, manufacturers must consider not only weld quality but also workpiece positioning, welding locations, and the coordination of operations across multiple blades.

When using general-purpose welding equipment, the operating process may still require adjustments to accommodate the product structure. The customer therefore needed an equipment solution tailored to the characteristics of the workpieces and the specific welding operation.

To address these requirements, PDKJ designed a dedicated welding machine around the welding positions, motion paths, and clamping methods required for fan blades. By integrating laser welding with three-axis motion control and a rotary positioning mechanism, the equipment is designed to better match the processing requirements of the specific product.

2. Coordinating Welding Positions, Motion Paths, and Workpiece Positioning

For welding fan blades to rotor cores, the project focused on three main considerations.

① Welding the Connection Between Fan Blades and Rotor Cores

The machine is designed to weld the connection points between the fan blades and the rotor core. Welding paths and process parameters can be determined according to the actual workpiece structure to meet the corresponding joint requirements.

② Positioning Multiple Blades and Coordinating the Welding Sequence

Fan blades must be positioned according to the workpiece structure and welded in sequence. The equipment design needs to account for blade positioning, rotor clamping, and angular indexing after each weld, helping reduce repeated manual adjustments between welding positions.

③ Coordinating Welding Motion with the Operating Sequence

During welding, the laser welding head follows a programmed trajectory while working in coordination with the workpiece positioning and rotary mechanisms to complete welding at different locations. The machine structure and operating sequence must be planned together to meet the processing requirements of the specific product.

Based on these requirements, PDKJ adopted a solution combining a three-axis platform with a rotary clamping mechanism. Welding motion, workpiece positioning, and angular indexing are integrated into a unified equipment design.

3. Key Features of the PDKJ Three-Axis Laser Welding Machine for Fan Blades

This project uses a 1500 W laser welding system equipped with three-axis motion modules, dedicated workholding fixtures, a laser welding head, and a rotary clamping mechanism. The machine is specifically designed around the fan blade welding process.

3.1 Three-Axis Motion for Programmed Welding Trajectories

The machine uses X-, Y-, and Z-axis motion modules to guide the laser welding head along programmed welding paths.

For the connection points between fan blades and the rotor core, welding trajectories can be planned according to the specific workpiece structure. This reduces reliance on manual handheld welding operations.

3.2 Dedicated Positioning Fixtures for Workpiece Clamping

The machine is equipped with positioning fixtures manufactured to suit the workpiece, together with a rotary clamping mechanism for positioning and securing the components.

Proper fixture design helps establish consistent workpiece loading positions and provides a stable basis for subsequent welding. The actual positioning accuracy and applicable range need to be verified through testing based on workpiece dimensions and clamping conditions.

3.3 Rotary Mechanism for Welding Multiple Blades

According to the machine design, the rotary mechanism changes the workpiece angle to accommodate different blade welding positions. After one blade position is welded, the fixture rotates to a preset angle for the next welding operation, continuing until the required welding sequence is completed.

This design coordinates blade positioning, angular indexing, and welding operations, making it suitable for applications that require sequential welding at multiple locations.

3.4 Dual-Station Design for Welding and Loading/Unloading

The machine adopts a dual-station configuration. While welding takes place at one station, operators can load or unload workpieces at the other.

This layout is intended to improve coordination between welding and material handling while reducing equipment idle time. Actual cycle time and productivity must be verified according to product specifications, operator proficiency, and on-site production conditions.

4. From Equipment Configuration to Production Implementation

For customized welding equipment projects, delivery involves more than simply manufacturing the machine. The equipment must also be configured to address the customer’s products and production requirements.

The PDKJ Three-Axis Platform Laser Welding Machine for Fan Blades has been delivered and put into production at the customer’s facility. Its transition from equipment design to practical manufacturing demonstrates the value of dedicated welding equipment in specialized production processes.

For manufacturers, a suitable dedicated welding machine can help align production operations more closely with product processing requirements. Whether it improves production efficiency, enhances weld consistency, or reduces manual operations must be assessed using actual production data, process validation results, and equipment operating performance.

PDKJ remains focused on customers’ practical welding requirements, developing equipment solutions based on workpiece characteristics and specific production processes.
