Abstract
A clamping device performs a clamping action when performing laser welding to join a first stripped portion, where a coating is absent from a first end, and a second stripped portion, where a coating is absent from a second end. A second claw extends in a radial direction of a second shaft. In a state in which a first shaft and the second shaft are moved toward a stator core such that the first end and the second end are sandwiched between the first shaft and the second shaft, and the first shaft is pressed against a second curved portion and the second shaft is pressed against a first curved portion, the clamping device performs the clamping action by rotating the second shaft about a center axis of the second shaft until the second claw comes into contact with the second end.
Claims7
A clamping device configured to hold a first coil segment and a second coil segment that are arranged on a stator core and coated with an insulative coating, wherein the clamping device is used when performing laser welding to join a first stripped portion, where the coating is absent from a first end of the first coil segment, and a second stripped portion, where the coating is absent from a second end of the second coil segment, the clamping device comprising:
- a first shaft arranged to extend in a radial direction of the stator core;
- and
- a second shaft arranged to extend in the radial direction of the stator core, wherein:
- the first shaft and the second shaft are spaced apart from each other in a circumferential direction of the stator core so that in a state in which the first shaft is pressed against the second coil segment and the second shaft is pressed against the first coil segment, the first shaft and the second shaft sandwich the first end and the second end and hold the first end and the second end in position in the circumferential direction of the stator core;
- and
- the clamping device is configured to clamp the first end and the second end in a state in which the first end and the second end are held in position in the circumferential direction of the stator core.
