Description

Technical Field

[0001] The utility model belongs to the technical field of iron core processing, and particularly relates to a stator iron core processing and welding device. Background Art

[0002] In order to improve material utilization, a winding process is currently used to manufacture the stator core, which is called the "coiling process". The teeth are first punched out of the steel strip, and then the strip is wound into a spiral shape. The teeth of each layer of the strip overlap, and the strip is cut after reaching the required thickness, and finally welded into shape.

[0003] The existing core processing and welding device usually directly places the stacked cores on the workbench, and then welds the cores with a welding gun. However, after welding, this method needs to wait for a certain period of time for cooling. Then the staff takes out the cores and replaces the cores to be welded, which will consume a lot of time and reduce work efficiency. Therefore, we propose a stator core processing and welding device.

By setting a rotating seat, the iron core at the center of the lifting seat can be welded, and the staff can place the iron core to be welded on the placement boss on the side away from the lifting seat again, or take out the welded iron core for replacement, without having to wait for cooling time separately, thereby improving work efficiency.

[0035] A specific application of this embodiment is:

[0036] When in use, first rotate the threaded ring 235 counterclockwise to make it away from the limiting plate 232 to release the fixation of the welding gun 231, then push or pull the welding gun 231 to drive the supporting slider 233 to slide on the limiting plate 232, and adjust the position of the welding gun 231.
