D28 3D welding table with universal clamping jigs

D28 3D welding table with universal clamping jigs offers comprehensive welding solutions for industrial applications.

• 3D Flexible Universal Fit: Five-face system with complete universal fixtures; capable of clamping square tubes, round tubes, frames, boxes, chassis, and irregular structural parts. One worktable handles all products, eliminating repeated custom tooling.
• High Precision and Excellent Product Consistency: CNC precision machining with standard hole spacing positioning ensures uniform workpiece dimensions in batch welding, compatible with assembly and robotic welding stations.
• Time Saving and Efficiency Improvement: No marking lines, angle irons, or temporary spot welding required; fixtures assemble quickly with changeover adjustments completed in minutes, saving over 70% of clamping time.
• Deformation Resistance and High Welding Quality: High-strength table with sufficient rigidity and multi-point balanced clamping effectively offsets welding thermal stress, reducing workpiece deformation and correction processes.
• Durable and Maintenance-Free: Nitrided hardened surface resists high temperatures, weld slag impact, and rust; heat-treated fixtures resist breakage and wear with service life exceeding 10 years.
• Unlimited Expansion and Splicing: Multiple D28 workbenches freely splice and combine to meet assembly and welding needs for oversized steel structure workpieces.

(Custom configurations available upon request.)

• Main body material: HT300/Q355B/S355J2N low-alloy high-strength steel
• Optional material: HT250 cast iron
• Machining process: Overall welding → Stress-relief annealing → CNC gantry milling finishing → Precision boring
• Surface treatment: Gas nitriding
• Nitriding layer thickness: 0.3mm
• Surface hardness: HRC 20-25
• Characteristics: Anti-weld slag adhesion, wear-resistant, high temperature resistant, rust-proof, and not easily deformed

All fixtures are standardized and modular, made of high-strength tempered carbon steel, and compatible with D28 hole positions, allowing for arbitrary splicing and combination:

• Positioning and Locking Fixtures: Five-ball locking pins, quick-positioning pins, eccentric locking pins, locking bolts, positioning sleeves; quick installation and disassembly, high locking force, and strong shear resistance.
• Angle Positioning Fixtures: 90° right-angle positioning blocks, L-shaped stops, angle plates, adjustable angle supports, V-shaped positioning blocks (specifically for positioning round tubes, square tubes, and shaft-type workpieces).
• Support and Elevation Fixtures: Adjustable support columns, fixed support blocks, extended columns, multi-layer elevation blocks, extended crossbeams; suitable for leveling and supporting workpieces of different heights.
• Clamping and Pressing Fixtures: Vertical quick-release clamps, horizontal clamps, spiral pressure plates, heavy-duty pressing modules, chain tensioning clamps, corner clamps; enabling secure fixation of workpieces at multiple angles to prevent welding displacement.
• Connection and Adapter Products: Adapter blocks, extension connectors, connecting plates, and elbow connectors used to extend the tooling range and connect multiple workbenches for joint use.
