[0050] The implementation principle of a new energy high-power motor rotor shaft processing device of this embodiment is as follows:

[0051] First, the staff places the two motor rotor shafts in the inner cavities of the first mounting ring 102, the first fixing plate 1022, the second mounting ring 1021 and the second fixing plate 1023 respectively (thereby the placed motor rotor shafts can be initially limited by the clamping plate 204, because one end of the clamping plate 204 is inserted into the third sliding rod 2043 in the circular mounting cylinder 2041, which can be moved with the assistance of the third sliding groove 2042 and the return spring 2045, so as to initially limit the motor rotor shaft). When the placement is completed, the staff controls the servo motor 1021 to move the motor rotor shaft 1023 by the controller. The servo motor 201 is in operation. When the servo motor 201 is in operation, it can drive the first threaded rod 2011 and the second threaded rod 2012 to rotate. When the first threaded rod 2011 and the second threaded rod 2012 rotate, it can drive the first threaded sleeve 2013 and the second threaded sleeve 2014 to move horizontally with the assistance of the first slide groove 2015 and the first slider 2016 (because the first threaded rod 2011 and the second threaded rod 2012 have opposite thread directions, they can drive the first threaded sleeve 2013 and the second threaded sleeve 2014 to move horizontally relative to each other);

[0052] When the first threaded sleeve 2013 and the second threaded sleeve 2014 move horizontally relative to each other, the placement plate 202 can be driven to move horizontally relative to each other. When the placement plate 202 moves horizontally relative to each other, the first mounting ring 102 and the second mounting ring 1021 can be driven to move relative to each other. When the first mounting ring 102 and the second mounting ring 1021 move, they can respectively squeeze the two motor rotor shafts to move relative to each other, thereby aligning the two motor rotor shafts with each other.

[0053] When the first threaded sleeve 2013 and the second threaded sleeve 2014 move horizontally, they can drive the connecting plate 2017 to move horizontally. When the connecting plate 2017 moves horizontally to a certain position, it can squeeze the wedge block 203 to move vertically up and down with the assistance of the second slide groove 2031 and the second slider 2032. When the wedge block 203 moves vertically upward, it can drive the top block 2033 to move vertically upward.

[0054] When the top block 2033 moves vertically upward, it will be able to squeeze the first movable plate 301 to move vertically upward with the assistance of the fourth slide groove 3011 and the fourth slider 3012. When the first movable plate 301 moves vertically upward, it will be able to squeeze the flip plate 302 to flip with the assistance of the rotating rod 3022. When the flip plate 302 flips, it will be able to drive the second movable plate 3015 to move vertically downward with the assistance of the fifth slide groove 3013 and the fifth slider 3014 through the slide rail 3016. Therefore, the placed motor rotor shaft can be clamped and positioned by the first movable plate 301 and the second movable plate 3015.

[0055] When the flip plate 302 flips, it can drive the lower sliding plate 3031 and the upper sliding plate 3034 to move vertically up and down with the assistance of the guide rod 303. When the lower sliding plate 3031 and the upper sliding plate 3034 move vertically up and down, they can drive the L-shaped mounting plate 3035 to move through the guide slider 3033. When the L-shaped mounting plate 3035 moves, it can drive the lower positioning rod 3036 and the upper positioning rod 3037 to move relative to each other, so as to position and clamp the placed motor rotor shaft.

[0056] When the motor rotor shafts are positioned, the staff can control the welding assembly 402 through the controller to weld the middle of the two motor rotor shafts.
