Typical application scenarios
1.Automobile manufacturing: Body welding, chassis parts fixing
2.Construction machinery: Welding of structural parts of excavators and cranes
3.Rail transit: Welding of high - speed rail/subway car bodies
4.Aerospace: Assembly and inspection of aircraft parts
5.Mold industry: Positioning and adjustment of large - scale molds
Advantages
(1) Design of D28 Standard Hole System
Use a positioning hole with a diameter of 28mm, and cooperate with a special locking pin and fixture to achieve rapid positioning and fixation.
The hole pitch usually follows a grid layout of 50×50mm or 100×100mm, adapting to the clamping requirements of workpieces of different sizes.
(2) Three - dimensional Flexible Adjustment
The position of the workpiece can be freely adjusted in the X/Y/Z three directions, which is suitable for welding complex structures.
It is equipped with a variety of adjustable fixtures, support blocks, and angle adjusters to meet the welding requirements at different angles.
(3) Modular Combination
The platform can be used individually or spliced together in multiple pieces to expand the working area (such as 3000×2000, etc.).
It supports standardized accessories (such as clamps, locating pins, universal wheels, etc.) to improve the efficiency of tooling.
(4) High Precision & High Rigidity
It is made of high - strength cast iron/alloy steel, and has undergone aging treatment to ensure no deformation during long - term use.
After precision grinding, the flatness error is ≤0.05mm/m², ensuring welding accuracy.
(5) Domestic Advantages
Direct sales from Chinese factories, with high cost performance.
