[0030] Fabricate the stator body and insert the short-circuit ring into the stator body;

[0031] S1. Stamping: The stator body is placed on the surface of the stamping machine conveyor plate. Then, the atomizing nozzle sprays oil onto the surface of the stator body.

[0036] S6. Welding: The stator body with the short-circuit ring inserted enters the guide frame of the welding machine. Then, the position sensor detects the stator body, and the welding gun is used to connect the short-circuit ring and the stator body more firmly.

[0037] S7. Oiling: After welding, the stator body enters the guide frame of the oiling machine, and oil is added to the inner tank. Then the stator body will be immersed in the inner tank, thus completing the oiling operation.

[0070] This application also discloses a manufacturing process for an electric motor stator, including the following steps:

[0071] Fabricate the stator body 1 and insert the short-circuit ring 2 into the stator body 1;

[0072] S1. Stamping: The stator body 1 is placed on the surface of the stamping machine conveyor plate 35. Then, the atomizing nozzle 34 sprays oil onto the surface of the stator body 1. Then, the stamping plate 310 stamps the stator body 1 to make the connection between the rivet and the stator body 1 more compact.

[0073] S2, Orientation: After stamping, the stator body 1 enters the guide frame 41 and moves to the surface of the connecting plate 46 under the action of the first automatic push plate 43. Then, the laser range sensor 47 detects the placement direction of the stator body 1, and the drive motor 45 drives the rotation of the connecting plate 46 to complete the orientation.

[0074] S3, Shaping: After the stator body 1 is adjusted, it enters the interior of the shaping machine guide frame 52. Then the impact plate 56 squeezes the stator body 1 to make the surface of the stator body 1 smoother.

[0075] S4. Thickness detection: After the stator body 1 is shaped, it enters the interior of the inspection machine guide frame 61. The height of the mounting plate 66 is adjusted. If the stator body 1 is compliant, it slides inside the inspection machine guide frame 61. If it is not compliant, it will touch the pressure sensor 67 and then trigger the alarm light 68.

[0076] S5, Inserting the short-circuit ring: After the thickness detection is completed, the stator body 1 enters the insertion ring guide plate 71. By adjusting the first hydraulic cylinder 72 and the second hydraulic cylinder 73, the locking block 75 is moved, which in turn moves the stator body 1. The automatic lifting device 78 drives the automatic mechanical claw 79 to grab the short-circuit ring 2. Then the automatic mechanical claw 79 moves to the upper part of the stator body 1, so that the short-circuit ring 2 is inserted into the stator body 1.

[0077] S6. Welding: The stator body 1 with the short-circuit ring 2 inserted enters the welding machine guide frame 83. Then, the position sensor 84 detects the stator body 1 and uses the welding gun 86 to connect the short-circuit ring 2 and the stator body 1 more firmly.

[0078] S7. Oiling: After welding, the stator body 1 enters the guide frame 92 of the oiling machine, and oil is added to the inner tank 93. Then the stator body 1 will be immersed in the inner tank 93, thus completing the oiling operation.

[0079] In use, the stator body 1 is first placed on the surface of the conveyor belt 37 of the stamping unit 3. Then, the micro-control motor 36 drives the conveyor belt 37 to rotate, which allows the stator body 1 to move. The atomizing nozzle 34 sprays oil from the oil tank 33. The stator body 1 then moves to the lower part of the atomizing nozzle 34, and the atomizing nozzle 34 sprays oil onto the stator body 1. The stator body 1 then moves to the lower side of the stamping plate 310. Because the hydraulic cylinder 38 of the stamping machine drives the stabilizing plate 39 to move downward, the stabilizing plate 39 contacts the buffer pad 311, which can squeeze the stamping plate 310. The stamping plate 310 then squeezes the stator body 1, which can fix the stator body 1 and the inserted rivets together. After the stamping is completed, the stator body 1 continues to move and enters the steering unit 4.

[0080] First, the stator body 1 slides to the right along the directional guide frame 41. Then, the directional hydraulic cylinder 42 lifts the stator body 1 upward so that the stator body 1 and the connecting frame 44 are at the same height. Then, the first automatic push plate 43 pushes the stator body 1 onto the surface of the connecting plate 46. The laser range sensor 47 detects the distance between the stator body 1 and the laser range sensor 47. When the distance is large, the drive motor 45 drives the connecting plate 46 to rotate 90° until the stator body 1 rotates to the appropriate angle. Then, the second automatic push plate 48 pushes the stator body 1 onto the sliding frame 49, and then it enters the shaping unit 5.

[0081] The stator body 1 enters the guide frame 52 of the shaping machine and continues to slide. When the stator body 1 is located under the impact plate 56, the shaping hydraulic cylinder 53 pushes the push plate 54 downward. Then the push plate 54 will press the impact plate 56 downward, so that the impact plate 56 can press the surface of the stator body 1, ensuring that the surface of the stator body 1 is smoother. Then the shaping hydraulic cylinder 53 rises, and the impact plate 56 will rise upward under the action of the reset device 55, so that the stator body 1 continues to slide and enters the interior of the thickness detection unit 6.

[0082] The device then rotates the threaded rod 64, which, due to the threaded connection between the threaded rod 64 and the nut sleeve 65, can drive the mounting plate 66 to rise and fall, thereby adjusting the height of the mounting plate 66. When the stator body 1 contacts the pressure sensor 67, the alarm light 68 will sound. The operator only needs to remove the non-compliant stator body 1, and the device can continue to work. Afterward, the compliant stator body 1 enters the ring inserter unit 7.

[0083] When the stator body 1 moves to the insert ring guide plate 71, as Figure 11 As shown, adjusting the first hydraulic cylinder 72 will drive the second hydraulic cylinder 73 to move to the left, which will drive the locking block 75 to move to the left. Then the stator body 1 will be fixed inside the locking block 75. Then the second hydraulic cylinder 73 will drive the inner plate 74 to move forward, so that the stator body 1 can move. At this time, the rotating motor 76 drives the rotating plate 77 to rotate, so that the automatic mechanical claw 79 is located above the placed short-circuit ring 2. Then the automatic mechanical claw 79 will grab the short-circuit ring 2. The automatic lifting device 78 will drive the automatic mechanical claw 79 to move upward. Then, through the rotation of the rotating plate 77, the automatic mechanical claw 79 can be located on the upper side of the stator body 1. Then the short-circuit ring 2 will be inserted into the interior of the stator body 1, and the stator body 1 will continue to move, so that the stator body 1 enters the welding unit 8.

[0084] After the stator body 1 moves to the position sensor 84, the welding hydraulic cylinder 85 is then activated, causing the welding gun 86 to move downward, thereby welding the stator body 1 and the short-circuit ring 2 together.

[0085] After welding, the stator body 1 enters the guide frame 92 of the oiling machine. Since the oil is added in the inner tank 93, the movement of the stator body 1 will immerse it in the inner tank 93, thereby completing the oiling process of the stator body 1. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.
