Welding Table Screw Clamp 3D Welding Table Fixture Clamp
The Welding Table Screw Clamp is a manual screw-type clamping accessory designed specifically for 3D flexible welding tables. It generates mechanical pressure through the rotation of a threaded spindle to securely fasten the workpiece to the table's hole pattern, thereby preventing displacement or deformation during welding.
Core Structure
| Base / Mounting Post |
Inserts into standard D16 or D28 welding tables for quick positioning and flexible relocation. |
| Vertical Post / Support Rod |
Height-adjustable; supports the clamping arm. |
| Screw and T-Handle |
Rotating the handle drives the screw downward to generate strong clamping force (approx. 5 kN / 1,100 lbs); features a self-locking mechanism to prevent loosening. |
| Pressure Head (Clamping Jaw) |
Applies direct pressure to the workpiece; interchangeable heads (45°/90°/180°) accommodate flat surfaces, angle iron, and round tubing. |
| Nitrided Surface |
Features a nitrided surface finish that resists weld spatter adhesion, offers high wear resistance, and ensures a long service life |
Common Types
- 90° Screw Clamp: Vertical downward clamping; most common type, used for flat surfaces and plates.
- 45° Screw Clamp: Angled clamping; suitable for angle iron, trusses, and corner welds.
- 180° Screw Clamp: Horizontal push-pull action; used to pull workpieces against positioning blocks or to correct deformation.
- Variable Throat Screw Clamp: Adjustable throat depth; suitable for both long and short workpieces.
Maintenance and Service Life
- Routine Cleaning: Remove welding slag and metal filings after use to prevent debris from entering the threads and impairing smooth operation.
- Lubrication: Apply a small amount of anti-rust lubricant to the screw spindle monthly to ensure smooth clamping and extend service life.
- Storage: When not in use for extended periods, wipe dry, apply oil, and store in a dry place to prevent rust.
- Replaceable Parts: The pressure head and screw spindle can be replaced individually, eliminating the need to discard the entire welding table screw clamp and keeping maintenance costs low.
- Service Life under Normal Conditions: 5-10 years (based on 8 hours of daily use).
FAQ
Q: What is the maximum clamping force?
A: The maximum clamping force reaches 5kN (about 1100 lbs). The trapezoidal thread features self-locking performance, so it will not loosen under vibration.
Q: What material and surface treatment do you use?
A: The main body is made of high-strength alloy steel with forging and tempering treatment. The surface adopts plasma nitriding, which is heat-resistant, anti-rust and resistant to weld spatter adhesion.
Q: How is it different from ordinary C-clamps?
A: Unlike general C-clamps, our welding table screw clamp is specially designed for 3D welding tables. It combines positioning and clamping functions, with higher precision, better stability and longer service life.
Q: What is the normal service life?
A: With correct operation and regular maintenance, the service life can reach 5 to 10 years.
