Description
Technical Field
The invention relates to the field of explosion-proof motors, in particular to an explosion-proof motor stator welding device.
Background
The explosion-proof motor does not generate electric sparks during operation, and is a motor used in flammable and explosive places.
The stator is the stationary part of the motor or generator. The stator consists of three parts, namely a stator iron core, a stator winding and a machine base.
After the existing stator is assembled, a reserved wiring harness on a coil needs to be externally connected with a patch cord, and the combination of the wiring harness and the patch cord is generally called as a combined wire; the wire head position needs to be welded after the external transfer line is connected; during welding, the stator is placed on the roller frame, and the roller frame and the stator are moved to a welding position through the conveying belt to be manually welded;
the existing method is that a single person generally holds a left-hand clamp and a right-hand oxyhydrogen welding gun for matching welding; in the welding process, a welding worker holds the position, close to the oxyhydrogen welding position of the wire head, of the adapter wire of the combined wire by a pair of pliers, and twists the adapter wire of the combined wire by the pliers after clamping to adjust the position of the wire head, wherein the adapter wire of the combined wire has a thicker diameter opening and different linear deformation twists; meanwhile, the left hand is generally a non-conventional hand, when the patch cord of the combined conductor is twisted by a pliers, the slip phenomenon is easy to generate, so that the patch cord of the combined conductor needs to be loosened and clamped for many times to match with the adjustment of a wire end, and a human body can involuntarily move along with the twist phenomenon, so that the flame of a hydrogen-oxygen welding gun held by the right hand is easy to contact with the patch cords of other combined conductors or insulating paper, and the patch cord rubber sleeve layer of the combined conductor is melted or the insulating paper is damaged;
furthermore, as the patch cord of the external combined conductor has fixed length and thick diameter, the patch cord of the combined conductor can generate drooping gravity, and welding personnel can easily clamp and separate when twisting the patch cord of the combined conductor; resulting in inefficient welding.
