Description

Technical Field

[0002] At present, the existing stator welding equipment is a single-gun single-weld mode equipment, which cannot weld all welding positions of the workpiece at the same time. The welding efficiency is low and the speed is slow. The clamping mechanism cannot maintain a constant and uniform clamping force when the workpiece is rotating. The welding effect is uneven and the welding quality cannot be guaranteed. The flatness error of the workpiece surface after welding will be very large. After a period of use, the accuracy of the welding position will be greatly reduced due to too frequent rotation of the workpiece.
