Abstract

The invention discloses a motor rotor welding assisting device which comprises a first tool and a second tool. The bottom of the first tool is provided with a first groove matched with the top of a motor rotor, the top of the second tool is provided with a second groove matched with the bottom of the motor rotor, the first tool is arranged above the second tool, and the first groove and the secondgroove define a space for containing the motor rotor. According to the motor rotor welding assisting device, the motor rotor is positioned through the first groove and the second groove in the welding process, and thus the positioning firmness degree of the motor rotor can be improved, and the welding accuracy is guaranteed.

Description

technical field [0001] The invention relates to a welding aid, in particular to a motor rotor welding auxiliary device. Background technique [0002] With the strong development momentum of new energy vehicles, new energy vehicles have higher and higher requirements for power consumption performance. The high-speed and high-torque characteristics of high-performance motors will inevitably increase the working intensity of the motor rotor. [0003] In the prior art, the motor rotor is usually manufactured by stacking conventional segmented iron cores, only relying on the interference fit connection between the iron core and the bracket. When the working strength of the motor rotor increases, this structure is gradually difficult to meet the demand. Therefore, it is necessary to weld and strengthen the motor rotor. [0004] In order to ensure the welding accuracy of the motor rotor, it is necessary to provide a motor rotor welding auxiliary device. Contents of the inventio...
