Description

Technical Field

The equipment is usually composed of a gantry, a multi-axis welding robot, a control system and other parts, and can realize precise welding operations in three-dimensional space. Therefore, before welding the workpiece through the gantry-type multi-axis welding equipment, it is necessary to position and fix the workpiece through a fixing part to ensure the accuracy of the welding process. The existing gantry-type multi-axis welding equipment mostly adopts a slider-type structure to slide the fixing part in the T-slot of the workbench.
