Company Profile

D28 3D Welding Table Triangular Support Bracket

Product Introduction

The D28 3D Welding Table Triangular Support Bracket is a core load-bearing and positioning module within the D28-series 3D flexible welding fixture system. It is primarily used for the right-angle or multi-angle support, positioning, and fixture expansion of heavy workpieces, utilizing a rigid triangular structure to provide high stability and load-bearing capacity.

Dimensions and Specifications

Specifications (L × W × T)	Hole diameter	Hole spacing	Primary uses
175×175×50	φ28	50/100	Small and medium-sized frames, housings, and 90° positioning
225×225×50	φ28	50/100	Versatile core style, workwear staple
275×275×50	φ28	50/100	Large and medium-sized workpieces, heavy-duty support
175×175×100	φ28	50/100	Thickened, heavy-duty, and deformation-resistant
275×275×100	φ28	50/100	Heavy machinery and thick-plate structures (primary heavy-duty applications)
325×225×50	φ28	50/100	Workpieces with height differences; auxiliary support for inclined surfaces
425×225×50	φ28	50/100	Multi-point support for long members and long frames
300×275×100	φ28	50/100	Extended-height triangular support; heavy-duty frame and housing
600×375×100	φ28	50/100	Extra-large workpieces and construction machinery frames

Core Functions and Applications

90° Precision Positioning: Provides a vertical reference, ensuring right-angle accuracy and preventing welding deformation; ideal for welding frames, housings, columns, and similar structures.
Heavy-Duty Support: Triangular structure distributes stress with load-bearing capacity of 5-25 tons, suitable for supporting heavy workpieces or serving as primary fixture support.
3D Expansion: Clamps, angle irons, V-blocks, and other accessories can be mounted on the vertical face to extend workspace and facilitate complex, multi-sided welding.
Height Adjustment: Units can be stacked or combined with square blocks to flexibly adjust workpiece height and accommodate various welding positions.
Anti-Tipping & Vibration Resistance: Stable triangular geometry effectively withstands welding stresses and vibrations, preventing workpiece displacement.

Installation Method

Mounts directly onto tabletops or vertical columns using D28 quick-locking pins.
Triangular support brackets allow for double-sided or three-way connections to assemble 3D fixture frameworks.
Can be freely combined with D28 square blocks, angle blocks, clamps, and locating pins.
Tool-free, rapid changeover; ideal for small-batch, high-variety production.

Precautions for Use

When positioning, ensure the base sits flush against the welding table surface; avoid unsupported configurations that can cause deformation and compromise accuracy.
The locking pin must be fully inserted and locked; verify overall stability after clamping to prevent shifting during welding.
When stacking multiple brackets, manage total height; for tall assemblies, use support columns for reinforcement to prevent tipping.
Do not use as a tool for hammering or prying, as impact forces can damage mounting hole precision and surface flatness.
