In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1-5 As shown, a motor shaft pressing device includes a punching machine 1, the punching machine 1 includes an operating table 2 and a punching head 3 located above the operating table 2, the operating table 2 is provided with a rotor positioning mold 4, the middle of the rotor positioning mold 4 is provided with a positioning groove 6 for inserting the power supply motor shaft 5, and the positioning groove 6 is provided with a plurality of positioning plates 9 for inserting the winding groove 8 of the rotor 7, and the positioning plates 9 are rotated on the rotor positioning mold 4, and the lower end of the punching head 3 is detachably connected with a pressing rod 10, and the lower end of the pressing rod 10 has a pressing groove 11 for inserting the power supply motor shaft 5, and the pressing groove 11 is provided with an upper magnet 12. During operation, the upper end of the motor shaft 5 is inserted into the pressing groove 11 of the pressing rod 10, and the motor shaft 5 is attracted by the upper magnet 12. The rotor 7 is placed on the rotor positioning mold 4, and the positioning plate 9 on the rotor positioning mold 4 is inserted into the winding groove 8 of the rotor 7 to achieve the positioning of the rotor 7. The punching machine is started, and the punching head 3 is lowered to insert the motor shaft 5 into the shaft hole of the rotor 7. After the lower end of the motor shaft 5 reaches the bottom of the positioning groove 6 , the punch head 3 rises, and the motor shaft 5 is separated from the pressure rod 10 .

[0020] Furthermore, the operating table 2 is provided with an initial positioning plate 13, which is detachably fixed on the operating table 2, and is provided with a positioning circular groove 14. The outer side of the initial positioning plate 13 is provided with a notch 15 connected to the positioning circular groove 14, and a positioning round table 16 is provided in the positioning circular groove 14. The upper surface of the positioning round table 16 is provided with an automatic adjustment groove 17, and the rotor positioning mold 4 is placed in the automatic adjustment groove 17. When the rotor positioning mold 4 is installed, the initial positioning plate 13 and the positioning round table 16 play a role in positioning the rotor positioning mold 4. The inner diameter of the automatic adjustment groove 17 is slightly larger than the outer diameter of the rotor positioning mold 4, so that the rotor positioning mold 4 has a certain activity space on the plane. When the motor shaft 5 is lowered, if there is a deviation between the motor shaft 5 and the shaft hole of the rotor 7 on the rotor positioning mold 4, the chamfering of the lower end of the motor shaft 5 is used to make the rotor positioning mold 4 automatically adjust its position on the horizontal plane and automatically calibrate. In this way, the motor shaft 5 and the rotor 7 are not damaged, and the quality of the motor is ensured. When the motor shaft insertion production is not needed, the initial positioning plate 13, the rotor positioning die 4 and the pressing rod 10 are disassembled, and the punching machine can be used for other punching production work.

[0021] Furthermore, a lower magnet 18 is provided at the bottom of the automatic adjustment groove 17, and the rotor positioning mold 4 can be attracted by the lower magnet 18. The lower magnet 18 prevents the rotor positioning mold 4 from moving randomly in the automatic adjustment groove 17 due to equipment vibration, etc. The rotor positioning mold 4 can overcome the magnetic force of the lower magnet 18 when automatically adjusting its position on the horizontal plane.

[0022] Furthermore, a lower copper plate 19 is provided in the automatic adjustment groove 17, the lower copper plate 19 is located above the lower magnet 18, and the lower copper plate 19 is movably placed in the automatic adjustment groove 17, and an upper copper plate 20 is fixed to the lower end of the rotor positioning mold 4. The cooperation of the lower copper plate 19 and the upper copper plate 20 reduces the friction between the rotor positioning mold 4 and the bottom of the automatic adjustment groove 17, ensuring that the rotor positioning mold 4 can smoothly adjust its position in the automatic adjustment groove 17.

[0023] Furthermore, a calibration die 21 is included, and a central hole 22 is provided on the calibration die 21 for inserting the motor shaft 5, and a plurality of calibration holes 23 are provided around the central hole 22 for respectively passing the positioning plate 9. When the initial positioning plate 13, the rotor positioning die 4, the pressure rod 10, etc. are just installed on the punching machine, the calibration die 21 is used to replace the rotor 7 for trial production to avoid the rotor 7 with a higher cost being damaged due to excessive error.

[0024] Furthermore, the upper end of the positioning plate 9 has a pointed portion 24. The pointed portion 24 can facilitate and quickly place the rotor 7 on the rotor positioning mold 4, thereby improving production efficiency.

[0025] The punching machine in the present application is a conventional small punching machine. The initial positioning plate 13 is installed on the operating table 2 by screws, and then the positioning table 16 is inserted into the positioning circular groove 14 from the notch 15, so that the positioning table 16 is close to the inner wall of the positioning circular groove 14, and the rotor positioning mold 4 is placed in the automatic adjustment groove 17 of the positioning table 16, and then the calibration mold 21 is installed on the rotor positioning mold 4, so that the positioning plates 9 of the rotor positioning mold 4 are respectively inserted into the calibration holes 23 of the calibration mold 21, and finally the punching head 3 of the punching machine is lowered, and the motor shaft on the punching head 3 can be smoothly inserted into the center hole 22 of the calibration mold 21 to complete the calibration, remove the calibration mold 21 and replace it with the rotor, and normal production can be carried out.
