D28/D16 Multifunctional Modular Welding Table
D28/D16 Multifunctional Modular Welding Table is a high-precision modular welding table that combines two standard hole systems, D28 (28mm hole spacing) and D16 (16mm hole spacing). It supports three-dimensional (3D) positioning and is suitable for welding, assembly and inspection of complex workpieces. Its core advantages lie in flexibility and versatility, and it can adapt to workpieces of different sizes and shapes.
Core Features
(1) Dual standard hole system design
D28 hole system (28mm spacing):
Suitable for medium and large workpieces (such as automobile chassis, steel structures).
Provide stronger fixture load capacity (such as hydraulic fixtures).
D16 hole system (16mm spacing):
Suitable for small precision workpieces (such as electronic parts, sheet metal parts).
Higher positioning density, accuracy can reach ±0.02mm.
(2) 3D modular function
Three-dimensional spatial positioning: Through support columns, angle adjusters and other accessories, X/Y/Z axis can be fixed in any direction.
Quick reconstruction: No need to customize tooling, just replace the fixture to adapt to new workpieces.
(3) Material and durability
Tabletop material:
Nitriding steel: Surface hardness HRC 60+, wear resistance, welding spatter resistance.
Alloy steel: Economical choice, requires regular maintenance.
Surface treatment: Rust-proof, high temperature resistant, some models with coolant tank design.
(4) Multifunctional expansion
Compatible fixture types:
Quick clamp, magnetic mount, vacuum suction cup (for non-metallic parts).
Universal angle gauge, extension arm (for complex structure welding).
Optional automation interface: docking with robot arm and AGV trolley to support intelligent production.

1.Modular Quick Changeover
The second - level installation of fixtures and positioning pins is achieved through the standard hole system, reducing the die - changing time by 80%.
Supports three - dimensional space combination (such as vertical brackets expanding the vertical working surface).
2. High Rigidity and Anti - Deformation
The tabletop thickness is 100 - 200mm. The static load can reach 2 tons/m² for D16 and 10 tons/m² for D28.
High - temperature resistant design (locally withstands 600ºC instantaneously).
3. Compatible with Automation
Integrated with robot welding arms and visual positioning systems (the RFID fixture identification module needs to be selected).

Selection and Usage Suggestions
1. Selection Principles
Precision First: Choose D16 (such as for the assembly of laser - cut parts).
Heavy - load Requirements: Choose D28 (such as for the welding of hydraulic press frames).
2. Maintenance Key Points
Regularly clean the oil stains inside the holes with alcohol to avoid fixture loosening.
For heavy workpieces, the load should be evenly distributed to prevent local deformation.
