Description

Technical Field

[0003] Welding is an important step in metal processing. When welding metal parts, the two parts to be welded will be clamped through a docking and positioning device so that the contact surfaces of the two metal parts are in contact with each other for easy welding. However, the two metal parts are prone to misalignment after clamping, but it is not convenient to change the relative positions of the parts during clamping. Moving the parts after loosening and clamping again can easily cause the two metal parts to be misaligned again. At the same time, since the welding surface is often a complete surface, after the existing device is clamped, it is not convenient for the staff to perform processing operations on different welding surfaces of the metal product, thereby increasing the possibility of multiple clamping by the staff and the existence of welding dead angles. At the same time, the placement and installation position of the welding table device in the workshop are different, resulting in the fixed installation holes on the welding table often not matching, affecting the use of the staff.
