[0002] The stator copper wire laser welding manual clamping fixture is a support device for positioning stator copper wire laser welding. It is a fixture for clamping the Xpin stator copper wire of new energy electric drive. When welding the Xpin stator copper wire, it is necessary to clamp and position the two sets of Xpin stator copper wires first. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of stator copper wire laser welding manual clamping fixture.

[0003] Existing manual clamping fixtures for stator copper wire laser welding have certain drawbacks.
