Pole iron core drilling die convenient to center

The utility model provides a magnetic pole iron core drilling die convenient for centering, which comprises a support and a magnetic pole iron core to be processed arranged on the support, and is characterized in that a template with a plurality of hole dies is arranged on the support, two ends of the template are respectively provided with a positioning slide block which is in sliding fit with the template, and the two positioning slide blocks are connected with a moving mechanism arranged on the template. The positions of the two positioning sliding blocks are synchronously adjusted and fixed through the moving mechanism, so that the center position of the template is aligned with the center position of the magnetic pole iron core to be machined, and then needed holes can be synchronously machined in a plurality of magnetic pole iron cores which are stacked into a whole after an existing drilling device is aligned with a hole die on the template, so that rapidness, high efficiency, accuracy and reliability
