[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a stator end plate auxiliary assembly structure with a positioning structure, including: a base 1;

[0029] A main support plate 2 is fixed to the top of the base 1. The base 1 supports the upper parts of the structure, while the main support plate 2 supports the stator end plate and stator core. A stator positioning rod 3 for precise positioning is provided on the rear top of the main support plate 2. The stator positioning rod 3 is used to clamp and position the stator end plate and stator core. A first support plate 4 and a second support plate 5 are rotatably mounted on the front area of ​​the main support plate 2. The first support plate 4 and the second support plate 5 are used to slide support the support block 6. A support block 6 is slidably mounted on the inner side of both the first support plate 4 and the second support plate 5. The top of these two support blocks 6 is also equipped with a stator positioning rod 3. When the lead screw 7 rotates, it will support the support block 6. The horizontal position of the support block 6 is adjusted so that the stator positioning rod 3 can position the stator end plate and the stator core. Two lead screws 7 are also rotatably installed on the inner side of the first support plate 4 and the second support plate 5. When the lead screws 7 rotate, they will adjust the horizontal position of the support block 6. A positioning plate 8 is firmly welded to one side of the first support plate 4 and the second support plate 5. The positioning plate 8 is used to support the positioning screw 9. A positioning screw 9 is installed on the positioning plate 8 by thread. After the first support plate 4 or the second support plate 5 is rotated and adjusted, the positioning screw 9 on the positioning plate 8 can be tightened. At this time, the positioning screw 9 will be in close contact with the top surface of the base 1, thus fixing the position of the first support plate 4 or the second support plate 5.

[0030] In this embodiment of the disclosure, such as Figures 1-5As shown, both the first support plate 4 and the second support plate 5 have a long strip opening at the top, and the stator positioning rod 3 at the top of the support block 6 can slide horizontally in the long strip opening. When the lead screw 7 rotates, it will adjust the horizontal position of the support block 6, so that the stator positioning rod 3 can position the stator end plate and the stator core. The long strip opening at the top of the first support plate 4 and the second support plate 5 can guide the stator positioning rod 3.

[0031] In this embodiment of the disclosure, such as Figures 3-5 As shown, a rectangular plate is provided at the end of the first support plate 4 and the second support plate 5 that are connected to the main support plate 2. The rectangular plates on the first support plate 4 and the second support plate 5 are staggered, so the first support plate 4 and the second support plate 5 are less likely to collide when rotating.

[0032] In this embodiment of the disclosure, such as Figures 1-3 and Figure 5 As shown, the bottom end of the positioning screw 9 can be tightly attached to the top surface of the base 1. Each support block 6 is provided with a threaded hole corresponding to the lead screw 7. After rotating and adjusting the first support plate 4 or the second support plate 5, the positioning screw 9 on the positioning plate 8 can be tightened. At this time, the positioning screw 9 will be tightly attached to the top surface of the base 1, thus fixing the position of the first support plate 4 or the second support plate 5. When the lead screw 7 is rotated, the horizontal position of the support block 6 can be adjusted.

[0033] In this embodiment of the disclosure, such as Figures 1-3 and Figure 6 As shown, a fan-shaped notch is provided on the bottom front side of the main support plate 2, and the thickness of the fan-shaped notch is equal to the total thickness of the rectangular plates on the first support plate 4 and the second support plate 5, so as to facilitate the rotation and adjustment of the first support plate 4 and the second support plate 5.

[0034] In this embodiment of the disclosure, such as Figure 5 As shown, a rectangular cavity is provided on the inner side of both the first support plate 4 and the second support plate 5. The outer wall of the support block 6 is in close contact with the inner wall of the rectangular cavity on the inner side of the first support plate 4 and the second support plate 5. When the lead screw 7 rotates, it will adjust the horizontal position of the support block 6. At this time, the support block 6 can slide stably in the rectangular cavity on the inner side of the first support plate 4 and the second support plate 5.

[0035] Example 2, based on Example 1, such as Figures 1-6 As shown, a hexagonal post is provided at one end of the lead screw 7. The top surfaces of the first support plate 4 and the second support plate 5 are on the same plane as the top surface of the main support plate 2. In use, the lead screw 7 can be rotated by using an Allen wrench in conjunction with the hexagonal post at one end of the lead screw 7. When the lead screw 7 rotates, it will adjust the horizontal position of the support block 6, thereby enabling the stator positioning rod 3 to position the stator end plate and the stator core. The first support plate 4 and the second support plate 5 can cooperate with the main support plate 2 to support the stator end plate and the stator core.

[0036] The working principle of this embodiment is as follows: When assembling the stator core and stator end plate using this structure, the base 1 can be placed on the processing table, then the stator core can be placed on top of the main support plate 2, and then the stator end plate can be placed on top of the stator core. One of the welding grooves on the outer side of the stator end plate and the stator core should be engaged with the stator positioning rod 3 on the rear side of the top of the main support plate 2. If the outer side of the stator end plate and the stator core has symmetrical welding grooves, then the first support plate 4 can be rotated to the front and the positioning screw 9 on the positioning plate 8 can be tightened. At this time, the positioning screw 9 will be in close contact with the top surface of the base 1, thus fixing the position of the first support plate 4. If the outer side of the stator end plate and the stator core does not have symmetrical welding grooves, then both the first support plate 4 and the second support plate 5 can be engaged. The stator is rotated and adjusted to align with the welding slots on the front side of the stator end plate and stator core. Then, the positions of support plate 4 and support plate 5 are fixed by positioning screw 9. At this point, the hexagonal post at one end of the lead screw 7 can be used to rotate the lead screw 7. When the lead screw 7 rotates, it will adjust the horizontal position of the support block 6, so that the stator positioning rod 3 on the top of the support block 6 can be moved synchronously and embedded into the welding slots on the front side of the stator end plate and stator core. This will accurately position and clamp the stator end plate and stator core. Then, the other exposed welding slots on the outside of the stator end plate and stator core can be welded to achieve assembly. After welding a part of the slots, the stator end plate and stator core can be disassembled. At this point, the two will be connected together, and then the welding of other slots can continue.
