The assembly mechanism can be horizontally rotated to above the placement seat 2 and the bushing guide assembly.

[0018] As a further improvement of this embodiment, the bushing guide assembly includes four guide cylinders 3 circumferentially distributed around the placement seat 2, four guide rods 4 arranged in the four guide cylinders 3 and slidable up and down, and reset springs 5 ​​surrounding the guide rods 4 are arranged inside the four guide cylinders 3. Two limit rings 6 are arranged on the upper and lower sides of the guide rods 4 inside the four guide cylinders 3, and the two ends of the reset springs 5 ​​in the four guide cylinders 3 are abutted on the two limit rings 6. The diameter of the guide rod 4 is smaller than the inner diameter of the bushing, and the guide rod 4 plays a role in providing guidance when the bushing is pressed.

[0019] As a further improvement of this embodiment, the assembly mechanism includes a rotating seat 7 arranged on the operating machine 1, a rotating column 8 installed on the rotating seat 7, and a mounting plate 9 fixedly connected to the top of the rotating column 8. The mounting plate 9 is provided with four through holes 10 corresponding to the upper and lower positions of the four guide rods 4, and the four through holes 10 are provided with filling components and press-fitting components. A rotation limit groove 11 is provided inside the rotating seat 7, and a rotation limit block 12 fixedly connected to the rotating column 8 is provided in the rotation limit groove 11. The rotation limit groove 11 is a semi-annular structure, that is, it provides a 180° rotation range for the rotation limit block 12; a rotating handle 13 is provided on the top of the rotating column 8 to facilitate the rotation of the rotating column 8.

[0020] As a further improvement of this embodiment, the filling assembly includes four material storage boxes 14 arranged on the mounting plate 9, four material pusher plates 15 arranged on one side of the four material storage boxes 14, and a material pusher cylinder 16 arranged on the outer box wall of the four material storage boxes 14 and connected to the four material pusher plates 15. The four material storage boxes 14 are all rectangular structures, and four drop holes 17 are arranged on the bottom of the box on one side of the four material storage boxes 14 away from the pusher plates 15. The four drop holes 17 correspond to the four through holes 10 one by one and have matching sizes. The material storage boxes 14 are used to store bushings, and each material storage box 14 can store a plurality of bushings.

[0021] As a further improvement of this embodiment, the press-fit assembly includes four guide posts 18 arranged on the mounting plate 9 and distributed circumferentially, four press-fit springs 19 arranged on the four guide posts 18, a press-fit plate 20 slidably connected to the four guide posts 18 and having its bottom abutted against the four press-fit springs 19, and four press-fit terminals arranged at the bottom of the press-fit plate 20. A pressing terminal 21 is arranged at the middle position of the press-fit plate 20, and the four press-fit terminals are located directly above the four through holes 10. The four press-fit terminals each include a connecting post 22 connected to the bottom of the press-fit plate 20, and a press-fit sheet 23 arranged at the bottom of the connecting post 22. The press-fit sheet 23 is a circular structure, and its diameter size is adapted to the diameter size of the through hole 10.

[0022] The working principle and use process of the present invention:

[0023] When in use, the motor is placed on the placement seat 2, and the guide rod 4 is required to pass through the mounting hole on the motor housing, and then the pump housing is pre-installed on the motor. At the same time, the guide rod 4 is also required to pass through the mounting hole on the pump housing. Then, by turning the handle 13, the rotating column 8 is rotated 180°, and the mounting plate 9 is located directly above the placement seat 2. Then, the pushing cylinder 16 on the four storage boxes 14 pushes the bushing to the drop hole 17 through the pushing plate 15, so that it passes through the through hole 10 and penetrates into the four guide rods 4, and then Afterwards, the pressing plate 20 is pressed downward by pressing the end head 21. Under the action of the guide column 18, the pressing plate 20 drives the four pressing ends vertically downward, passes through the drop hole 17 and the through hole 10, and presses the bushing into the mounting through hole of the motor and the pump casing to realize the bushing assembly; during the pressing process, the guide rod 4 is forced to move downward, and the reset spring 5 is compressed. After assembly, the pressing plate 20 is reset under the action of the press spring 19, and the electronic water pump with the bushing assembled is removed, and the guide rod 4 is reset under the action of the reset spring 5.
