Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, in particular to a clamp for assembling transformer cores. Background Art

[0002] The transformer core is composed of silicon steel sheets. To reduce heat loss in the core, the core is stacked with silicon steel sheets with a thickness of 0.23-0.5mm. The silicon steel sheets used in the transformer have a relatively high silicon content. Both sides of the silicon steel sheets are coated with insulating varnish, which can insulate the stacked silicon steel sheets from each other. The thickness of the insulating varnish is only a few microns. After the coil and core are completed, the next step in the transformer is assembly. To ensure its mechanical structure and achieve installation, it needs to be fixed using a clamping device. However, the existing transformer core processing clamping equipment generally uses a fixed plate for clamping. This clamping equipment has poor applicability and cannot meet the clamping needs of transformer cores of different sizes. Therefore, to address the above problems, it is now necessary to improve it.
