Problems solved by technology

[0002] When the compressor uses copper-aluminum composite rotors, the end rings are copper end rings, and the rotor guide bars are aluminum bars. During the manufacturing process, the copper end rings are easy to move, which affects the circulation of the aluminum liquid, and eventually leads to broken bars after the rotor is cooled. problem, increase in defect rate

Abstract

The invention discloses a rotor machining method that includes the following steps of: S10, fixing two end rings to the two axial sides of a rotor core respectively by connecting members, wherein therotor is provided with multiple rotor slots arranged at intervals, the two end rings are provided with through holes, and each rotor slot on the rotor core has corresponding communicating through holes on at least one of the two end rings after the fixation; S20, placing the fixed two end rings and the rotor core in a casting mold provided with a casting port rightly facing at least one through hole; and S30, pouring a metal solution into the through hole and a rotor slot communicating with the through hole from the casting port, and enabling the metal solution to form a first rotor bar aftercooling. According to the rotor machining method, when the rotor bar are casted, the two end rings do not move so that the fluidity of the metal solution is improved, and the defective rate of the cooled first rotor bars is reduced.

Description

Technical field [0001] The present invention relates to the technical field of motors, in particular to a method for processing a rotor. Background technique [0002] When the compressor uses a copper-aluminum composite rotor, the end ring is a copper end ring, and the rotor guide bar is an aluminum bar. During the manufacturing process, the copper end ring of the lead wire is easy to clump, which affects the liquidity of the aluminum liquid, and finally causes the rotor to break after cooling Problem, the defect rate has increased. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention provides a rotor and a processing method. The rotor is processed by the processing method, and the rotor guide bar is not easy to break and the defective rate is low. [0004] The method for processing a rotor according to an embodiment of the present invention includes the follow...
