[0031] This embodiment discloses a synchronous motor stator processing technology, as Figures 1-7 shown, including the following steps

[0032] S1: Cutting, cutting the cylindrical silicon steel coil into silicon steel sheets;

[0033] S2: Stamping, stamping the above-mentioned silicon steel sheets into punched sheets by using stamping equipment;

[0035] S4: Installing insulating paper, inserting insulating paper into the above-mentioned iron core;

[0036] S5: Threading, threading copper wires into the insulating paper of the above-mentioned iron core.

[0037] As Figures 2-3As shown, the stamping device includes a support table 4. A hollow mounting shell 1 is fixedly arranged on the support table 4. A power motor 5 is fixedly arranged inside the mounting shell 1. The upper side of the output end of the power motor 5 is connected to a power output shaft 6 through a bevel gear set. A turntable 8 is slidably arranged in the middle of the power output shaft 6. An amplitude adjustment component is arranged inside the turntable 8 for adjusting the position of the power output shaft 6 relative to the axis of the turntable 8. The outer side of the turntable 8 is rotatably connected to a crank 7. The lower side of the crank 7 is hinged to a pressure plate 17. Positioning components are arranged on both sides of the pressure plate 17 for assisting the pressure plate 17 to perform reciprocating motion in the up and down directions. The other side of the power output shaft 6 is fixedly provided with a driving gear 20. The driving gear 20 is meshed with a discharging component for removing the punched sheet after stamping. An installation hole is formed in the support table 4. A power disk 27 is rotatably arranged in the installation hole. A transmission component is arranged on the lower side of the power disk 27 for providing a power for the rotation of the power disk 27.

[0038] A stamping die adapted to the stamping of silicon steel sheets is installed on the lower side of the pressure plate 17 by screws. First, the silicon steel sheet to be stamped is conveyed to the support table 4 below the pressure plate 17 through an external conveying device including but not limited to a conveyor belt. According to the requirements of stamping the silicon steel sheet, the amplitude adjustment component is adjusted to adjust the power output shaft 6 to a suitable position relative to the turntable 8. Then, the power motor 5 and the transmission component work. The output end of the power motor 5 drives the power output shaft 6 to rotate through the bevel gear set, thereby driving the turntable 8 to perform an eccentric motion, and further driving the pressure plate 17 to perform reciprocating motion in the up and down directions through the crank 7, facilitating the stamping of the silicon steel sheet by the pressure plate 17, and discharging the punched sheet after stamping through the discharging component.

By rotating the adjustment rod, the adjustment rod drives the adjustment screw 24 to rotate, and the adjustment screw 24 drives the sliding plate 22 to move, thereby adjusting the sliding plate 22 to different positions relative to the axis of the turntable 8, facilitating the adjustment of the stroke of driving the crank 7 to perform reciprocating motion in the up and down directions through the rotation of the turntable 8, and facilitating the efficient stamping of silicon steel sheets with different thicknesses by the pressure plate 17.

[0040] As Figures 4-5As shown in the figure, the discharging component includes a transmission gear 19 meshed and connected with the driving gear 20.

A discharge plate groove is formed in one side of the lower part of the mounting shell 1. A discharge push plate 15 is inserted into the discharge plate groove. An auxiliary plate 28 is fixedly arranged on the side of the discharge push plate 15 close to the push rod 21. A groove is formed in the auxiliary plate 28. The lower side of the push rod 21 is located in the groove and is inserted into the groove. The driving gear 20 drives the transmission gear 19 to rotate. The transmission gear 19 drives the first transmission rod to rotate. The first transmission rod drives the second transmission rod 11 to rotate through the bevel gear set. The second transmission rod 11 drives the booster disk 13 to rotate. The booster disk 13 drives the push rod 21 to rotate. The push rod 21 drives the auxiliary plate 28 to make a reciprocating motion along the length direction of the power output shaft 6, so that the discharge push plate 15 moves the stamped silicon steel sheet away from the booster disk 13, facilitating the unloading of the punched sheet after stamping.

[0041] The positioning component includes rib plates 18 fixedly arranged on the upper side of the pressure plate 17, and insertion rods 16 symmetrically inserted on both sides of the rib plates 18, enabling the pressure plate 17 to freely move up and down along the insertion rods 16. A fixing plate 9 is fixedly arranged on the upper side of the insertion rods 16. The fixing plate 9 is fixedly arranged with the mounting shell 1. A limiting cap is fixedly arranged at the lower end of the insertion rods 16, used to limit the distance of the downward movement of the pressure plate 17.

[0042] The transmission component includes a servo motor 10 fixedly arranged on the lower side of the support table 4. The servo motor 10 here belongs to the prior art and will not be elaborated too much here. The output end of the servo motor 10 is connected with a short shaft 26 through a bevel gear set. The short shaft 26 is fixedly arranged with the power disk 27. By starting the servo motor 10 to drive the short shaft 26 to rotate, the silicon steel sheet placed on the power disk 27 is driven to rotate through the power disk 27, facilitating the stamping of the silicon steel sheet.

[0043] A support frame 2 is fixedly arranged on the lower side of the support table 4. The support frame 2 here has a supporting function. A sleeve plate 12 is fixedly arranged on one side of the mounting shell 1. The second transmission rod 11 is rotatably arranged with the sleeve plate 12, thus ensuring the stability of the rotation of the second transmission rod 11.

[0044] As Figure 7As shown, lifting screws are threadedly connected to the lower sides of the four peripheries of the support frame 2. An adjusting nut is fixedly connected to the lower part of the lifting screw. The lower end of the lifting screw is rotatably connected to a floor bolt 3. The floor bolt 3 at this position has a supporting function. By using a wrench to rotate the adjusting nut, the lifting screw rotates, thereby changing the distance between the floor bolt 3 and the bottom of the support frame 2, facilitating the placement of the stamping equipment on an uneven ground and ensuring the stability during the stamping of silicon steel sheets.

[0045] The lever 21 is located at a non - central position of the assisting disk 13, facilitating the assisting disk 13 to drive the auxiliary plate 28 to make a reciprocating motion along the length direction of the power output shaft 6 through the lever 21.
