3D welding tables rely on a standardized hole system and modular fixtures to realize fast tooling combination,which greatly shortens preparation time and improves production efficiency.
First,analyze the workpiece shape and positioning requirements.Clarify the datum plane,clamping points and welding direction to determine the layout of fixtures.This ensures accurate positioning and avoids interference during welding.
Second,place positioning pins and locking bolts into the D16 or D28 grid holes according to the workpiece size.Positioning pins provide accurate and consistent reference,while locking bolts fix fixtures firmly to the tabletop.
Third,install basic clamping modules such as angle blocks,V-blocks,pressure plates,support arms and stoppers.These standard parts can be combined freely to adapt to square,round,special-shaped and large structural workpieces.Quick‑clamp components further speed up installation.
Fourth,adjust and fix the tooling frame.Use extension arms and auxiliary supports to build multi‑station or three‑dimensional positioning structures for complex workpieces.Tighten all fasteners to ensure stability and prevent displacement during welding.
Fifth,perform trial positioning and verification.Place the actual workpiece on the assembled tooling to check alignment,gap and clamping reliability.Make micro‑adjustments if necessary to achieve ideal positioning.
With this method,tooling combination can be completed in minutes instead of hours.The reusable fixture system supports flexible switching between different workpieces,making it highly suitable for small‑batch,multi‑variety and customized welding production.
