The invention provides a magnetic pole iron core drilling die convenient to center, which comprises a support and a to-be-processed magnetic pole iron core 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 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 are achieved, and the production efficiency is improved. The problems that in the prior art, centering is not accurate, drilling quality is difficult to guarantee, and drilling efficiency is low due to the fact that the length of a magnetic pole iron core changes are solved.
Description
technical field [0001] The invention designs a drilling mold, in particular a magnetic pole iron core drilling mold which is convenient for centering, and belongs to the technical field of mold design and manufacture. Background technique [0002] The magnetic pole core is an important magnetic induction component that constitutes the excitation magnetic field of the generator and the synchronous motor. It is used to fix the magnetic pole coil after being connected with the motor yoke. The connection between the magnetic pole core and the magnetic yoke is generally done by bolts, T-slots, pigeon tail slots, etc. When assembling, it must be ensured that the length center of the magnetic pole core and the length center of the magnetic yoke are in the same position, otherwise the magnetic pole center will be inconsistent. Mechanical unbalance and electromagnetic unbalance, resulting in mechanical vibration and electromagnetic vibration. For the magnetic pole core connected wit...
