Description

Technical Field

[0001] This application belongs to the technical field of motors. More specifically, it relates to a welding tooling and a welding machine using the welding tooling. Background Art

[0002] After the flat wires are inserted into the stator of the motor, the ends of the flat wires need to be welded. Since there is a gap between two adjacent flat wires, a welding tooling is usually used to clamp the flat wires, thereby improving the welding quality of the flat wires.

[0003] Currently, the welding tooling usually uses two rotating disks to rotate relative to each other to clamp the flat wires. Specifically, through holes for the flat wires to pass through are respectively formed in the two rotating disks, and the two rotating disks rotate in opposite directions so that two adjacent through holes approach each other to clamp the flat wires. After welding, the two rotating disks rotate in the forward direction so that two adjacent through holes move away from each other to release the clamping of the flat wires. However, the relative rotation between the two rotating disks requires a large manual force, resulting in a poor clamping effect of the two rotating disks on the flat wires.
