Abstract

The invention relates to a glue filling device for magnetic steel sealing of a motor rotor of a hybrid electric vehicle and a glue filling method thereof. Compared with the prior art, the defect that the magnetic steel is difficultly sealed in the motor rotor can be solved. A runner plate is circular, the bottom of the runner plate is provided with a key groove, a glue inlet and a plurality of runners are installed at the center of the upper surface of the runner plate, the runners are distributed around the glue inlet in the shape of center divergency, one end of the runner is communicated with the glue inlet, the other end of the runner is provided with a glue filling opening, the runner plate is installed on a rotor core and the key groove of the runner plate is matched with the key of the rotor core. When the runner plate is installed on the rotor core, a plurality of the glue filling openings are respectively positioned above a plurality of sealing clearances of the rotor core. The glue filling device is capable of conveniently and efficiently pressing the thermocuring material into the sealing clearances of the magnetic steel, and effectively and stably fixing the magnetic steel on the motor rotor.

Description

technical field [0001] The invention relates to the technical field of motor rotors, in particular to a glue filling device and a glue filling method for the magnetic steel bundle seal of a hybrid electric vehicle motor rotor. Background technique [0002] Hybrid electric vehicles are now widely used in daily life. The spatial layout of hybrid electric vehicle motors is very compact, and its rotor adopts a structure without a pressure plate, which is different from the pressure plate structure of the traditional pure electric vehicle motor rotor. The risk of falling off is increased during the process, which puts forward higher requirements for the bundle seal of the rotor magnet. At the same time, the motor rotor of hybrid electric vehicles adopts the form of 4-stage lamination, which requires seamless press-fitting, which puts forward higher requirements for the surface flatness of the rotor core. After the rotor magnetic steel beam is sealed, there should be no protrud...
