The invention provides a process and a device thereof for sticking magnetic steel on a rotor of a high-power
permanent magnet motor for vehicles, relating to a
permanent magnet motor, in particular to a process device and a process for sticking the magnetic steel on the rotor of the
permanent magnet motor. The device comprises a support, a press plate, supporting sleeves, an auxiliary guide supporting block, a mold sleeve, a guide supporting sleeve, a nut pushing block and a locking screw. The process comprises the following steps of: assembling a motor rotor to be stuck with the magnetic steel with the left supporting sleeve, the right supporting sleeve, the auxiliary guide supporting block, the mold sleeve, the guide supporting sleeve and the nut pushing block into a whole in the process for sticking the magnetic steel on the rotor of the permanent
magnet motor and then supporting on the support; and
coating viscose glue on an opening of the mold sleeve, placing the magnetic steel in an axial positioning slot, rotating the nut pushing block, then pushing the mold sleeve and the magnetic steel to move ahead, and then sticking the magnetic steel on the outer circle of the motor rotor to form
magnetic poles. The device has the advantages of novel concept, compact structure, easy fabrication and convenient use, and 36 blocks of magnetic steel are stuck once so that the sticking process is simplified, the sticking quality is improved, the efficiency is improved, the cost is reduced, and the process and the device are suitable for
batch production. The invention can be widely applied to production enterprises of the permanent
magnet motor.
