D28 3D Welding Table System for Flexible Jig and Fixture Setups

Our D28 3D Welding Table System for Flexible Jig and Fixture Setups is a modular 5-face 3D welding fixture solution with Φ28 H7 hole system on 100×100 mm grid. It enables fast flexible jig and fixture setups without custom tooling. Stress-relieved base material plus plasma nitriding guarantees high precision, anti-spatter performance and heavy-load capacity. Widely applied for chassis, heavy structural fabrication and robot welding stations, the system supports table splicing and full-range standard accessories for flexible production.

• D28 Welding Table Body: 5 sides with standard D28 grid holes; X/Y millimeter graduations on the table surface for easy reading and positioning.
• Support Leg Assembly: Adjustable horizontal support legs; adjusts the table height by 800-900mm; adjusts the platform surface.
• Complete Set of Modular Fixture Accessories (Core Flexible Tooling):
  • Positioning: Positioning pins, V-blocks, right-angle rulers, stops, positioning supports
  • Clamping: Quick-locking pins, screw clamps, toggle clamps, pneumatic/hydraulic clamping modules
  • Support Adjustment: Adjustable support blocks, height-increasing pads, angle adjustment blocks
  • Connecting Splicing Components: Splicing pins, connecting plates, enabling expansion by splicing multiple worktables.
• Optional Expansion: Robot base interface, flip tooling, rotary worktable.

• Flexibility and Cost-Effective Tooling: No need for individual welding molds for each workpiece; standard components can be reassembled, and new product tooling can be switched, completing the process within hours.
• 3D Spatial Clamping (3D Core): Holes on all four sides, not just the table surface, allow for multi-angle positioning and clamping of the workpiece in the side and height directions, enabling welding of complex steel structures and frame-like workpieces.
• Heavy-Duty and High Rigidity: The D28 welding table has large apertures and strong locking force, making it suitable for heavy-duty welding of large steel structures, engineering machinery, vehicle frames, containers, pressure vessels, etc.
• Stable Precision: Aging stress relief + nitriding wear resistance ensures high repeatability and positioning accuracy even after repeated fixture disassembly and assembly, reducing welding misalignment and dimensional errors.
• Automation Compatibility: Perfectly integrates with robotic welding workstations and can be programmed with measurement protocols for use in automated production lines.
