In order to achieve the above purpose, the present utility model provides the following technical solutions: the copper end ring structure for the motor rotor comprises an end ring and a conducting bar, wherein welding auxiliary mechanisms are arranged on the end ring and the conducting bar;

the welding auxiliary mechanism comprises a plug hole formed in the surface of the end ring, a clamping groove is formed in the inner side surface of the plug hole, a clamping spring is movably mounted in the clamping groove, an arc-shaped clamping block is fixedly mounted on one side surface of the clamping spring away from the clamping groove, bolts are fixedly mounted at two ends of the guide bar, and an annular groove is formed in the surface of the bolt.

Further, the number of the plug holes is ten, and the distances between every two adjacent plug holes are equal.

Further, the plug holes are matched with the bolts.

Further, the number of the arc-shaped clamping blocks is eleven, and the distances between every two adjacent arc-shaped clamping blocks are equal.

Further, the arc-shaped clamping block is matched with the annular groove.

Further, the bolt is arc-shaped at one end surface far away from the guide bar.

Compared with the prior art, the technical scheme of the application has the following beneficial effects:

this copper end ring structure for motor rotor through having seted up the spliced eye at the end ring surface, be equipped with the jump ring in the spliced eye, be equipped with the arc fixture block on the jump ring, be equipped with the bolt on the conducting bar, the ring channel has been seted up at the bolt surface, only need insert the spliced eye with the bolt during the use, make arc fixture block card go into in the ring channel can link together conducting bar and end ring, and then conveniently weld end ring and conducting bar, convenient to use is swift, the welding efficiency of end ring and conducting bar has been improved greatly, it is inconvenient to fix a position and temporarily fix between conducting bar and the end ring to have solved current end ring when the welding, so it is laborious to waste time when the welding, lead to the lower problem of packaging efficiency of end ring and conducting bar.
