Brushless motor rotor core shaft pressing tool

The utility model discloses a brushless motor rotor core shaft pressing tool, which comprises a lower die sleeve and a pressing head, and is characterized in that two T-shaped grooves are symmetrically arranged on two sides of a central hole of the lower die sleeve, and positioning magnetic steels are respectively embedded in the two T-shaped grooves and are used for positioning a rotor core inserted into the lower die sleeve; elastic pressing blocks are symmetrically arranged at the lower end of the pressing head in the radial direction, the center line of each elastic pressing block is parallel to the center connecting line of the two pieces of positioning magnetic steel, and the inner end of each elastic pressing block is inserted into a center hole of the pressing head and used for achieving circumferential positioning of the iron core shaft. The press-fitting device has the advantages that automatic circumferential positioning after the iron core shaft is inserted can be achieved through the elastic pres
