[0034] Further, by Figure 1 and Figure 5-Figure 8 As shown, in order to increase the service life of the hollow rotating platform 19, the buffer portion includes a movable plate 14, a fixed plate 15, a plurality of slide bars 16 and buffer springs 17 corresponding to the slide bars 16 one by one; The fixed plate 15 is fixedly connected to the output end of the hollow rotating platform 19, and the sliding rods 16 are slidably arranged around the fixed plate 15. The upper end of each sliding rod 16 is fixedly connected to the bottom of the movable plate 14, and each buffer spring 17 is sleeved on the outer side of the corresponding sliding rod 16. The two ends of the buffer spring 17 are respectively abutted against the upper side of the fixed plate 15 and the lower side of the movable plate 14, and the receiving seat 46 is fixedly connected to the movable plate 14; In this embodiment, the number of the sliding bars 16 is four; It should be further explained that the bottom of the rotor shaft 8 has two symmetrically distributed opening grooves 50. In order to prevent the rotor shaft 8 inserted in the connecting member 47 from shaking and misaligning during rotation, the end of the positioning block 48 close to the opening groove 50 is provided with a protrusion integrally formed with the positioning block 48. When the rotor shaft 8 is inserted into the connecting member 47, the two opening grooves 50 at the bottom of the rotor shaft 8 are just engaged with the protrusions of the positioning block 48 at the corresponding positions, thereby realizing the positioning of the rotor shaft 8. When in use, the rotor shaft 8 is inserted into the interior of the connecting piece 47 through the receiving seat 46. In order to ensure that the key slots 10 of multiple magnetic steel blocks 12 are misaligned at a certain angle, the hollow rotating platform 19 drives the fixed plate 15, the sliding rod 16 and the movable plate 14 to drive the receiving seat 46 to rotate, and then drives the rotor shaft 8 to rotate through the connecting piece 47 and the positioning block 48 to ensure precise misalignment; in the process of pressing the end plate 13 and the magnetic steel block 12, the buffer spring 17 buffers part of the pressure to reduce the extrusion on the hollow rotating platform 19.

The staff aligns any end groove 9 on the first end plate 13 with the lower end of the square block 39. When the staff pushes the end plate 13 upward to engage with the square block 39, the end plate 13 pushes the support column 31 upward. When the diffuse reflection photoelectric 35 senses the upper end of the support column 31, the diffuse reflection photoelectric 35 gives a signal, and the clamping claw cylinder 42 starts the two clamping plates 43 to move closer to each other, thereby clamping the end plate 13. Subsequently, the servo electric cylinder 20 pushes the assembly plate 25 downward until the first end plate 13 is press-fitted onto the rotor shaft 8, thereby achieving press-fitting of the first end plate 13; Next, the servo electric cylinder 20 moves the clamping and positioning assembly 2 up to the original position, the staff places the magnetic steel block 12 under the pre-positioning plate 45, and the thin cylinder 2 30 pushes the limit column 34 down, so that the lower end of the limit column 34 extends to the bottom of the pre-positioning plate 45. The staff aligns the already determined adapter hole 11 on the magnetic steel block 12 with the lower end of the limit column 34. When the staff pushes the magnetic steel block 12 up to engage with the limit column 34, the magnetic steel block 12 pushes the stop column 31 upward. When the diffuse reflection photoelectric 35 senses the upper end of the stop column 31, the diffuse reflection photoelectric 35 gives a signal, and the clamping claw cylinder 42 starts the two clamping plates 43 to move closer to each other, so as to clamp the magnetic steel block 12. Then, the servo electric cylinder 20 pushes the assembly plate 25 downward until the magnetic steel block 12 is pressed onto the rotor shaft 8, thereby realizing the press-fitting of the magnetic steel block 12; Furthermore, when the magnetic steel block 12 is continuously pressed, in order to make the key slots 10 on the peripheral sides of the plurality of magnetic steel blocks 12 form a certain angle of misalignment, before the press-fitting, the hollow rotating platform 19 drives the rotor shaft 8 to rotate at a certain angle; Furthermore, in order to ensure that the key slots 10 on the plurality of magnetic steel blocks 12 are in the same viewing direction, when clamping the magnetic steel blocks 12, the position where the next magnetic steel block 12 is engaged with the limiting column 34 (i.e., the engagement of the adapting hole 11 with the limiting column 34) is determined according to the pressed magnetic steel block 12 until the press-fitting of the plurality of magnetic steel blocks 12 is completed; Finally, the tooling personnel places the second end plate 13 below the pre-positioning, and the thin cylinder 1 36 pushes the square block 39 downward, so that the lower end of the square block 39 extends to the bottom of the pre-positioning plate 45. The staff aligns any end groove 9 on the first end plate 13 with the lower end of the square block 39, and then repeats the steps of press-fitting the first end plate 13; The above process realizes the press-fitting of the rotor.

[0036] The present invention has a novel structure, an ingenious conception, and is simple and convenient to operate.
