D16/D28 3D Modular Fixture Welding Tables and Clamping Systems
Core Composition of the System
1. Workbench Body
• Material:
Tabletop: Q355B high-strength steel (or upgraded to Q460), with hard chromium plating/sandblasting for rust prevention on the surface.
Base: Welded steel structure (cast iron shock-absorbing base is optional).
• Hole System Standards:
D16: Holes with a diameter of 16mm, arranged in a 50mm×50mm grid, with a positioning accuracy of ±0.05mm.
D28: Holes with a diameter of 28mm, arranged in a 100mm×100mm grid, with stronger load-bearing capacity.
• Dimension Specifications:
Standard single table size: 1200×800mm, 2000×1000mm (multiple tables can be spliced for expansion).
2. Fixture System
• Mechanical Fixtures: Lever quick clamps, screw pressure plates (suitable for D16/D28 hole systems).
• Hydraulic/Pneumatic Fixtures: Automatic locking, adjustable pressure (external power unit required).
• Special Modules: Angle adjustment blocks, V-shaped positioning seats, universal ball tables, etc.
| Aspect |
Cast Iron |
Q355 (Structural Steel) |
| Material Category |
Iron-carbon alloy with high carbon content (2-4%), produced by casting. |
Low-alloy high-strength structural steel (GB/T 1591-2018), produced by rolling/forging. |
| Common Types |
Gray Iron, Ductile Iron. |
Replaces the old grade Q345. |
| Key Composition |
High carbon (2-4%), high silicon (1-3%), low manganese (0.1-1%). |
Low carbon (≤0.24%), low silicon (≤0.55%), manganese (1.0-1.6%), with microalloys (Nb, V, Ti). |
| Mechanical Properties |
- Tensile Strength: 120-400 MPa (low) |
- Tensile Strength: ≥355 MPa (actual: 470-630 MPa) |
| - Brittle, low toughness |
- High toughness, impact resistance |
| - High hardness (HB 150-300) |
- Moderate hardness (HB 130-180) |
| - Poor weldability. |
- Excellent weldability. |
| Manufacturing Process |
Casting (molten metal poured into molds). Ideal for complex shapes. |
Hot/cold rolling, forging. Easy to cut, weld, and machine. |
| Applications |
Engine blocks, machine tool bases, pipes, cookware (e.g., cast iron pans). |
Structural frameworks (buildings, bridges), ships, pressure vessels, machinery. |
| Advantages |
Cost-effective, wear-resistant, good vibration damping. |
High strength-to-weight ratio, ductile, suitable for dynamic loads. |
| Limitations |
Brittle, difficult to machine post-casting. |
Requires corrosion protection in harsh environments. |

D16/D28 3D Modular Fixture Welding Tables and Clamping Systems
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 - 150mm. 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.
Q: What's the lead time for custom configurations?
A: Standard units ship in 3-5 business days. Custom builds require 2-3 weeks for production.
