[0002] At present, motor rotors mostly use magnetic steel sheets, and the magnetic steel sheets need to be pressed into the slots on the rotor one by one. The current existing magnetic steel press-fitting production method is to manually install the N-pole and S-pole magnetic steel sheets into the corresponding slots of the rotor core one by one, and move the rotor to a manually operated pressing jig, and then the workers manually operate the jig to press the magnetic steel sheets into the rotor. At present, this manual pressing method is inefficient and not conducive to production. In order to meet the needs of automatic pressing of motor magnetic steel sheets, it is necessary to develop a device suitable for automatically pressing magnetic steel sheets into the rotor core.

The pressing seat 60 is arranged below the magnetic steel pressing part 20. Specifically, the magnetic steel pressing part 20 is rectangular and arranged vertically, and the magnetic steel pressing part 20 is provided with multiple magnetic steel sheets corresponding to the multiple magnetic steel sheets on the motor rotor A1. The upper surface of the pressing seat 60 is provided with a first guide mechanism 80 to prevent the magnetic steel pressing part 20 from being deflected, and the second lifting mechanism 70 is arranged on the work station 10. During operation, the press-fitting table 40 is moved out from under the magnetic steel pressing part 20 through the transverse movement mechanism 50, and the worker installs the motor rotor A1 onto the press-fitting table 40, and further inserts the magnetic steel sheet A2 into the groove A3 on the motor rotor A1. After assembly, the rotor on the press-fitting table 40 is moved again to under the first lifting mechanism 30 through the transverse movement mechanism 50. After it is in place, the pressing seat 60 is driven by the second lifting mechanism 70 to press the rotor of the motor to prevent shaking. The magnetic steel pressing part 20 is further lowered through the first lifting mechanism to press the magnetic steel into the groove on the rotor. During the pressing process, the magnetic steel pressing part 20 is guided by the first guide mechanism 80. After pressing, it is reset and moved out of the press-fitting table 40 through the transverse movement mechanism 50. The pressing process is completed automatically. Compared with the traditional method of manually operating the jig, the efficiency can be further improved, the quality of pressing can be guaranteed, and the labor intensity of the workers is also reduced.

[0029] In this embodiment, the press machine also includes a second guide mechanism 90 for guiding the up and down movement of the pressing seat 60 to ensure the operational stability of the pressing seat 60.

Specifically, the pressing seat 60 is disc-shaped, and the sleeves 92 on the plurality of guide posts 91 are all connected to the pressing seat. The disc-shaped pressing seat 60 can ensure that its up and down movement process is synchronized with the connection position of the plurality of guide posts 91, thereby improving stability and facilitating seating.

[0030] In this embodiment, the first guiding mechanism 80 includes a cylindrical body 81, the lower end of the cylindrical body 81 penetrates into the lower surface of the pressing seat 60, and the upper end surface of the cylindrical body 81 is longitudinally penetrated by a guide hole 110 for the magnetic steel pressing part 20 to move up and down, so as to prevent the magnetic steel pressing part 20 from bending during the pressing process.

The cylindrical body 81 and the pressure seat 60 are both detachably connected to the fixed plate 120.

The fixed plate 120 is provided with an avoidance hole 130 for the magnetic steel pressing part 20 to pass through. The fixed plate 120 not only serves to fix the cylindrical body 81 on the pressure seat 60, but also cooperates with the pressure seat 60 to press the motor rotor.

There are two guide rails 150, both of which are fixed on the work station 10 and parallel to the moving direction of the active end of the transverse movement mechanism 50, so as to assist the sliding of the mounting seat 41. In addition, it also prevents the downward pressure of the first lifting mechanism 30 from being directly transmitted to the transverse movement mechanism 50, causing the parts to be damaged by pressure.

[0034] In this embodiment, the first lifting mechanism 30 is a screw motor module to achieve high-precision pressure control. The second lifting mechanism 70 and the lateral movement mechanism 50 are both cylinders, which are easy to control and only need to ensure that the press-fitting table 40 moves back and forth between two positions.
