It is an important part of the transformer steel structure. At present, in the process of processing the core clamp, it is necessary to drill circular holes with different diameters at different positions in the horizontal and vertical directions of the clamp so that the clamping screw and the tensioning screw pass through the clamp to clamp and compress. Therefore, positioning tooling is needed to locate the drilling position of the core clamp.
