The invention discloses a drive motor stator shrinkage fit device which comprises a rack, a Y-direction moving tray mechanism, an X-direction moving tray mechanism, a heating mechanism and a press fitting mechanism. The Y-direction moving tray mechanism is arranged on the rack in the mode that the Y-direction moving tray mechanism can move in the Y direction, and the X-direction moving tray mechanism is arranged on the Y-direction moving tray mechanism in the mode that the X-direction moving tray mechanism can move in the X direction. The heating mechanism comprises a first fixing frame and a heating assembly capable of heating a motor shell, the press-fitting mechanism comprises a second fixing frame and a press-fitting assembly capable of fixing a stator assembly, and the first fixing frame and the second fixing frame are fixed to the rack in the X direction at intervals. The heating assembly is arranged on the first fixing frame in the mode that the heating assembly can move in the Z direction, and the press-fitting assembly is arranged on the second fixing frame in the mode that the press-fitting assembly can move in the Z direction. According to the invention, the coaxiality of the stator assembly and the motor shell can be ensured, and the assembly quality is ensured.
Description
technical field [0001] The invention relates to the assembly of a driving motor, in particular to a shrink-fitting device for a stator of a driving motor. Background technique [0002] With the rapid development of the new energy vehicle industry, car companies are gradually deepening the research and development and production of key components, and the core products are completely self-integrated and self-made. Such as figure 1 As shown, the drive motor 1 includes a positioning assembly 11 and a motor housing 12. Under the condition of small batch production, the traditional stator shrink-fit assembly process is manually assembled. First, the motor housing 1 is heated to expand it. Then use the hoisting machine to shrink fit the stator assembly 11 into the motor casing 12. During the shrink fit, it needs to be installed in place at one time in time, which puts forward very high requirements on the efficiency and success rate of assembly. Since the stator assembly 11 and ...
