Description

[0002] The pole core is made of multiple layers of silicon steel sheets, and multiple pole cores are evenly distributed on the circumference of the rotor yoke at a specific interval. In order to fix the pole core to the rotor yoke, it is necessary to drill holes on the bottom of the pole core and fasten it to the rotor yoke with bolts. However, the pole core has an irregular shape and is difficult to clamp. It is necessary to design a special drilling tool to ensure processing accuracy and improve production efficiency.

[0003] To this end, the patent specification with the publication number CN213225221U discloses a pole core drilling tool, including a bottom plate, a pressure plate and a positioning plate, the bottom plate is provided with a supporting positioning structure for supporting the pole core; the pressure plate includes at least two groups, and is fixed on the bottom plate at intervals, the pressure plate is provided with a positioning groove for the pole core to pass through and longitudinally position, and the pressure plate longitudinally positions the pole core from both sides of the pole core; the positioning plate is supported on the pressure plate, the positioning plate includes a hole template and a transverse positioning structure provided at both ends of the hole template, the hole template is provided with a positioning hole for the drill bit to pass through when drilling a hole in the pole core, and the transverse positioning structure is pressed on both ends of the pole core to transversely position the pole core.

Therefore, it is necessary to optimize and improve its structure. Utility Model Content
