3D Modular Welding Table System

1. Workbench surface (platform)
◦ Material: Usually made of high-strength cast iron or high-quality steel, subjected to stress relief and precision machining to ensure long-term dimensional stability and flatness.
◦ Hole system: The workbench surface is covered with standardized, high-precision grid holes. The most common hole diameters are Φ28mm (D28 system) and Φ16mm (D16 system), etc. The inner walls of the holes are quenched and ground, featuring high hardness and wear resistance.
◦ Grid spacing: There is a fixed and precise distance between holes (such as 100mm, 50mm), which provides a reference for positioning.
2. Functional modules (accessories)
This is the soul of the system, with an extremely rich variety, mainly including:
◦ Positioning blocks/support blocks: Used to support workpieces, available in various heights and sizes.
◦ Angle devices: Provide fixed angles such as 90 degrees, 45 degrees, 30 degrees, etc., for positioning workpieces with angle requirements.
◦ Clamps: Quick clamps, bolt pressure plates, etc., used to firmly clamp the workpiece on the support.
◦ Locating pins/locating bolts: Inserted into the platform holes, serving as precise reference points for workpieces or other accessories.
◦ V-blocks: Used to clamp cylindrical workpieces.
◦ Extension plates/connecting plates: Used to connect multiple workbenches together to expand the working area.
3. Fastening elements
◦ Mainly refer to high-strength double-ended bolts, nuts and washers. They pass through the platform holes and the holes on the functional modules to firmly lock all components together.
