[0041] Reference Figure 8 and Figure 9 When the roller 99 is located at the front end of the first horizontal slot 95, the clamp 94 is in a vertical position, used to clamp the horizontal rotor core. After the clamp 94 clamps the rotor core, the rodless cylinder 31 drives the clamp mounting block 92, the clamp mounting seat 93, and the clamp 94 to move backward. When the roller 99 reaches the inclined slot 96, the clamp mounting seat 93 and the clamp 94 begin to rotate. When the roller 99 reaches the second horizontal slot 97, the clamp mounting seat 93 and the clamp 94 rotate 90 degrees, the clamp 94 is in a horizontal position, and the rotor core is in a vertical position. Similarly, when the clamp mounting block 92, the clamp mounting seat 93, and the clamp 94 move forward, the clamp 94 returns to its vertical position.

[0042] Reference Figure 1 、 Figure 3 、 Figures 5 to 10The design principle of the present invention is as follows: the clamp 94 clamps the rotor core 34, the clamp mounting block 92, the clamp mounting seat 93 and the clamp 94 move backward to send the rotor core 34 to the top of the core tooling 7, and then the core tooling 7 rises to receive the rotor core 34. After the core tooling 7 completes receiving the rotor core 34, it is lowered so that the rotor core 34 is located in the space surrounded by the seven partition blocks 5. At the same time, the clamp mounting block 92, the clamp mounting seat 93 and the clamp 94 are reset, and then the pressing cylinder 8 is lowered and drives the seven pressing plates 6 to move inward, so that the seven pressing plates 6 simultaneously close and flatten the seven horn protrusions 39, and then the pressing cylinder 8 is raised, the seven pressing plates 6 are reset, and the core tooling 7 rotates a certain angle, and the pressing cylinder 8 is lowered again to continue to close and flatten the next group of seven horn protrusions 39. The pressing cylinder 8 is repeatedly lowered and raised to achieve the closing and flattening of all the horn protrusions 39 of the rotor core 34. In this embodiment, the seven pressing plates 6 only need to move inward three times to complete the closing and flattening of all the horn protrusions 39 of the rotor core 34 .

[0043] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
