Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric drive assembly technology of electric vehicles, and in particular relates to an electric drive assembly jig and method for electric vehicles. BACKGROUND

[0002] At present, the electric drive assembly jigs in the prior art are mostly applied to automatic mass production lines with high precision and short tact time. In the process of flexible, economical and high-quality sample trial production and small batch trial production, the traditional electric drive assembly method adopts manual assembly. During the assembly process, a large magnetic pull force is generated between the stator and the rotor, and direct collision between the stator and the rotor is prone to occur, which causes scratches on the surface of the iron core or copper wire, affects the precision of the assembly process, and it is difficult to guarantee high quality requirements. Although the assembly jig suitable for automatic mass production lines can guarantee high quality requirements, the cost of the jig is relatively high, and the jig needs to be replaced in the product iteration process, which cannot meet the economic needs. At the same time, the jig cannot achieve the goal of flexible product trial production because it cannot produce multiple products alternately. SUMMARY

[0003] The purpose of the present application is to provide an electric drive assembly jig and method for electric vehicles. The feeding and assembly of the jig are divided into two parts, which do not affect each other. The reducer assembly, the rotor assembly and the stator shell assembly are connected by a sliding mechanism and are axially centered and assembled. This method effectively avoids the eccentric magnetic pull force caused by the eccentricity of the stator and rotor during assembly, which causes the stator and rotor to attract each other, resulting in quality problems such as winding insulation and bearing damage. The light-weight fast pull pin and locking mechanism are convenient to disassemble and adapt to the structure of the electric drive assembly jig in the trial production stage. When the product is changed, only the suspension point and bearing hole position of the different types of reducers need to be changed. The profiled lifting appliance can be changed according to the shape of the motor shell. The remaining structural components do not need to be changed, which has high economy and universality.
