Product Description

Modular welding table 3D welding fixture table With D28 Adjustable clamping

The modular 3D welding fixture workbench (D28 system) is an industrial - grade precision welding platform. It adopts a 28mm standard hole - pitch system and is equipped with adjustable fixtures. It is specifically designed for heavy - duty welding, large - scale structural component assembly, and complex tooling manufacturing. Its core advantages lie in high load - bearing capacity, modular expandability, and a three - dimensional adjustable fixture system, which can significantly improve welding accuracy and efficiency.

Core features

(1) D28 Modular Hole System
• 28mm Standard Hole Spacing: The worktable is covered with precisely machined positioning holes (usually Φ28mm or with M16 threads), with a spacing of 28mm, balancing strength and flexibility.
• Heavy-duty Load-bearing: The load-bearing capacity of a single unit can reach over 5000kg, suitable for heavy welding of large steel structures, construction machinery, etc.
• Expandable and Splicable: Multiple units can be spliced horizontally/vertically to form a larger working area (such as an automobile body welding line).
(2) 3D Adjustable Fixture System
• Omni-directional Clamping: The fixture can be fixed at any position in the X/Y/Z three directions, supporting:
Vertical/horizontal clamping
Angle adjustment (0° - 360°)
Cantilever extended clamping (for special-shaped parts)

• Quick Replacement: The fixture (such as lever fixture, pneumatic fixture, etc.) can be disassembled/installed without tools.

(3) High-strength structural design
• Tabletop material:
Cast iron tabletop (HT300 grade, surface quenched and hardened) - High shock resistance, suitable for arc welding.
Steel tabletop (Q235/S355JR, precision ground) - Lightweight, suitable for robotic welding.
• Support frame: Heavy-duty steel base (square tube ≥100×100mm), with options of fixed type or with brake casters.
(4) Intelligent adaptation
• Automated integration: Can be connected to welding robots, AGV conveyor lines, and some models support CNC programming to control fixtures.
• Digital management: Mark the fixture positions through QR codes/RFIDs to achieve rapid production changeover.

Selection and Maintenance Suggestions

(1) Selection Points
• Tabletop Dimensions: It is recommended to add 300mm to both the length and width of the maximum workpiece size (to facilitate fixture arrangement).
• Fixture Configuration: Hydraulic/pneumatic fixtures should be selected for heavy workpieces, and magnetic fixtures can be additionally configured for thin sheet workpieces.
• Expansion Requirements: If future automation upgrades are needed, electrical interfaces should be reserved.

(2) Maintenance
• Daily Inspection: Clean welding slag (especially in holes) and check the fixture locking mechanism.
• Quarterly Maintenance: Recalibrate the tabletop level and lubricate moving parts.
• Long - term Protection: The cast iron tabletop should be regularly coated with anti - rust oil to avoid long - term immersion in coolant.

After Sales Service

Standard Warranty: 12 months or 2,000 operating hours (whichever comes first).
Extended Warranty: Optional coverage up to 36 months.
Global Support: 24/7 technical assistance and spare parts supply.
Training: On-site or remote operation/maintenance training.
