technical field

The utility model relates to the field of motor manufacturing, in particular to an embedded permanent magnet motor magnetic steel assembly device.

Background technique

At present, when assembling the magnetic steel of the embedded permanent magnet motor, a non-magnetic push rod is generally used to withstand the magnetic steel, and the other end uses a hand hammer to hit the push rod to push the magnetic steel into place. This assembly process is not only inefficient, but also difficult to guarantee product performance, because the material of the magnetic steel is brittle, frequent knocking will cause damage to the magnetic steel, and the damaged magnetic steel is not easy to replace, which will cause the loss of magnetic force of the magnetic steel and affect product performance, resulting in unnecessary loss. In addition, a plurality of magnetic steels of the same polarity are installed along the axial direction, and the magnetic steels of the same polarity repel each other, and the outermost magnetic steels are easily ejected, which poses a great potential safety hazard.

The purpose of the utility model is to overcome the above defects and provide a simple, safe and reliable embedded permanent magnet motor magnet assembly device.

The technical scheme of the utility model is: an embedded permanent magnet motor magnetic steel assembly device, which includes a motor rotor iron core, a motor rotor end plate, a non-magnetic push rod, and also includes a guide seat and a positioning plug-in. The positioning groove of the guide seat and the positioning slot of the positioning insert are arranged on the board. The positioning groove of the guide seat matches the positioning convex strip at the bottom of the guide seat. The design position matches, the guide seat is provided with a magnet steel channel matching the magnet steel block, the magnet steel channel matches the iron core groove, one or more magnet steels are placed in the guide seat magnet steel channel, no The magnetic push rod pushes the magnetic steel into the iron core slot of the motor rotor, and after the magnetic steel on the same bus is pushed into the iron core slot, the positioning insert is inserted into the positioning slot of the positioning insert on the end plate of the motor rotor.

In order to facilitate the alignment of the magnetic steel channel and the iron core groove as much as possible, a sample push plate is also included, the sample push plate is arranged between the non-magnetic push rod and the magnetic steel, and the sample push plate and the non-magnetic push rod are fixedly connected Together, the cross-sectional size of the model push plate is larger than the cross-sectional size of the magnetic steel and smaller than the cross-sectional size of the iron core slot.

In order to protect the magnetic steel from damage, it also includes a spacer, the spacer is provided with a surface on which the magnetic steel is supported, and the material of the spacer is nonmagnetic soft metal.

The beneficial technical effect of the utility model is that since the motor rotor iron core end plate is provided with a guide seat positioning groove and a positioning insert positioning groove, the positioning of the guide seat and the rotor iron core is reliable, and the magnetic steel guide seat can be verified by a sample push plate Whether the notch is aligned with the notch of the rotor iron core magnetic steel, the sample push plate is connected with the non-magnetic push rod, and the magnetic steel can be pushed into the iron core slot smoothly. After the magnetic steel on the same busbar is assembled, the positioning plug is inserted into the motor rotor The magnetic steel is fixed in the positioning groove of the positioning plug-in of the end plate, and the magnetic steel will not pop out, so it is safe and reliable.
