Double-sided adsorption motor iron core lower die fixing tool

The utility model provides a double-sided adsorption motor iron core lower die fixing tool, which is characterized in that an upper accommodating cavity and a lower accommodating cavity are arranged in a support shell, the two accommodating cavities respectively correspond to two mutually independent magnetic seats, and the two magnetic seats are respectively controlled by two control parts on a control panel; the bottom surface of the supporting shell is sucked with a machining table surface of a punching machine, so that the device is fixed on the machining table surface of the punching machine; when the magnetic base arranged on the upper portion works, the supporting plate and the lower die are attracted, so that the lower die is fixed only under the condition that acting force is exerted on the lower portion, and changes of the perpendicularity of a characteristic hole are reduced. The upper end face of the supporting shell is provided with a supporting plate, the supporting plate comprises a fine grindi
