[0028] A type of wound stator assembly, such as Figures 1-7 As shown, the stator core 1 includes a stator core 1 with several wire-inserting grooves 2 on its inner wall. Several winding bodies 24 are formed between the wire-inserting grooves 2. A coil group 3 is wound between two winding bodies 24. Fixed rings 4 are fixedly installed on the outer wall of the stator core 1 near both ends. Movable rings 5 are movably installed at both ends of the stator core 1. Several connecting mechanisms are provided between the outer wall of the movable rings 5 and the fixed rings 4. Several auxiliary mechanisms are provided on the side of the movable rings 5 near the stator core 1. The auxiliary mechanisms include a base plate 6, which is fixedly connected to the outer wall of the movable rings 5. Two vertical plates 8 are fixedly installed on the upper surface of the base plate 6. Connecting shafts 9 are rotatably connected to the outer walls of the two vertical plates 8. A rhombus-shaped block 7 is fixedly installed between the two connecting shafts 9. Rollers 10 are rotatably connected to the upper and lower ends of the rhombus-shaped block 7.
[0029] A vertical rod 12 is fixedly installed on one side of the upper surface of the base plate 6. A pressure block 11 is sleeved on the outside of the vertical rod 12. A support spring is sleeved on the outside of the vertical rod 12 and between the pressure block 11 and the base plate 6. Slide rods 18 are fixedly installed on both outer walls of the base plate 6. Pull rods 17 and return springs are sleeved on the outside of the two slide rods 18. A pull plate 13 is movably installed on one side of the base plate 6. The pull plate 13 is fixedly connected to one end of the two pull rods 17. The rhombus block 7 is initially vertical, with both ends abutting against the pressure block 11 and the base plate 6 respectively. The pressure block 11 is away from the base plate 6, and the support spring is stretched. When the pressure block 11 is released and the rhombus block 7 is rotated 90° to a horizontal position, the pressure block 11 can be moved down along the vertical rod 12 under the action of the support spring.
[0030] The outer wall of the pull plate 13 is fixedly connected to the second fixing rod 16 and the first fixing rod 15. The outer wall of the connecting shaft 9 is fixedly connected to the connecting plate 14. The outer wall of the connecting plate 14 is provided with a first fixing hole, and the first fixing hole is matched with one end of the first fixing rod 15. The outer wall of the vertical rod 12 is provided with a second fixing hole, and the second fixing hole is matched with one end of the second fixing rod 16.
[0031] In use, the coil group 3 is wound outside the winding body 24 formed by the plurality of embedded slots 2, and the coil group 3 is located between the bottom plate 6 and the pressing block 11 and closely adheres to the upper surface of the bottom plate 6. After winding, the pull plate 13 is pulled away from the bottom plate 6, and the two pull rods 17 slide along the slide rod 18 following the pull plate 13. The reset spring is pressed, which can drive the fixed rod one 15 and the fixed rod two 16 to move out of the fixed hole one and the fixed hole two, respectively, and release the fixing of the diamond block 7 and the pressing block 11, respectively. Then the diamond block 7 is rotated 90° through the connecting shaft 9, so that the two rollers 10 are tightly attached to the bottom surface of the pressing block 11 and the upper surface of the bottom plate 6, respectively. The distance between the pressing block 11 and the bottom plate 6 is reduced, so that the pressing block 11 can slide along the outside of the vertical rod 12 to press the coil group 3, and the thickness of the coil group 3 can be limited. Then the pull plate 13 is loosened, and under the action of the reset spring, the pull rod 17 moves along the slide rod 18 to the initial position, and the fixed rod one 15 is inserted into the fixed hole one in the abutment plate 14, and the fixed rod two 16 is inserted into the fixed hole two through the pressing block 11.

One end of the pull spring is fixedly connected with the clamping block 22, and the other end of the pull spring is fixedly connected with the movable block 20.
[0033] Specifically, the clamping block 22 is moved away from the movable block 20, so that the end of the clamping block 22 moves out of the clamping groove 23, the telescopic connecting rod 21 is elongated, and the pull spring is stretched. Then the clamping block 22 is rotated 90° around the connecting position between the movable block 20 and the L-shaped connecting block 19, so as to release the fixing between the fixed ring 4 and the movable ring 5. At this time, the movable ring 5 can be taken out from one end of the stator core 1, so as to take out each bottom plate 6 from the inside of the stator core 1, thereby facilitating the workers to remove each bottom plate 6 as a whole. Not only is it convenient to overhaul the inside of the stator core 1, but also it is convenient to overhaul each auxiliary mechanism.
