Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1 As shown, the assembly equipment for the starter rotor includes a frame 1, on which a slide plate 2 is slidably connected, and on the slide plate 2 are a plurality of positioning shafts 21 for positioning the rotor core 5.

[0030] Specifically, such as Figures 1-4 As shown, this assembly equipment also includes a lifting plate 3 and a pressure plate 4 that are mounted on the frame 1 and can be raised and lowered independently. The lifting plate 3 is located between the pressure plate 4 and the slide plate 2. A guide sleeve 31 is vertically fixed on the lifting plate 3. A top pressure rod 32 is slidably inserted into the guide sleeve 31. When the lifting plate 3 descends, the guide sleeve 31 can be fitted onto the rotor shaft 6 so that the top pressure rod 32 is pushed out by the rotor shaft 6 inside the rotor core 5. When the pressure plate 4 descends, it can press the top pressure rod 32 downward.

[0031] Working principle: By sliding a slide plate 2 on the frame 1, the rotor core 5 can be positioned within multiple positioning shafts 21, thus achieving the positioning of the rotor core 5. Then, the lower end of the rotor shaft 6 is manually inserted into the rotor core 5. Sliding the slide plate 2 so that it is positioned below the lifting plate 3, when the lifting plate 3 descends, the guide sleeve 31 can be fitted onto the rotor shaft 6, causing the top pressure rod 32 to push upward under the resistance of the rotor shaft 6. The guide sleeve 31 moves downward along the top pressure rod 32, and the guide sleeve 31 can be fitted onto the rotor shaft 6. The pressure plate 4 descends and presses down the top pressure rod 32, which presses the rotor shaft 6 into the rotor core 5. Inside, the top pressure rod 32 is limited by the inner wall of the guide sleeve 31, thus ensuring that there is no displacement deviation in the left and right directions during the pressing process. This avoids the low efficiency of assembling the rotor core 5 onto the rotor shaft 6 as in existing methods. Instead, the rotor shaft 6 is directly inserted. By adding a lifting plate 3 between the pressure block and the slide plate 2, and through the cooperation of the guide sleeve 31 and the top pressure rod 32 on the lifting plate 3, the guide sleeve 31 can limit the top pressure rod 32 and also initially limit the rotor shaft 6, improving the stability of the pressing process. This improves assembly efficiency while ensuring assembly quality.

[0032] The rack 1 is provided with a driving part one 7 for driving the lifting plate 3 to lift and a driving part two 8 for driving the pressing plate 4 to lift.

[0033] The driving part one 7 and the driving part two 8 can be oil cylinders or air cylinders.

[0034] The lifting plate 3 and the pressing plate 4 can also be manually pushed.

[0035] As shown in Figure 3 , Figure 4 the upper end of the top pressing rod 32 always extends out of the guide sleeve 31, the upper end of the top pressing rod 32 is provided with a limiting shoulder 32a in the shape of a round plate, the limiting shoulder 32a always locates outside the guide sleeve 31, the lower side of the pressing plate 4 is fixed with a pressing head 41, the pressing head 41 can press on the limiting shoulder 32a, and the diameter of the pressing head 41 is smaller than the diameter of the limiting shoulder 32a.

[0036] As shown in Figure 1 , Figure 3 and Figure 4 , the lower end face of the lifting plate 3 is provided with a positioning hole 33 corresponding to the positioning shaft 21, the positioning shaft 21 can be inserted into the corresponding positioning hole 33, and the rack 1 is provided with a plurality of guide columns 11, the guide columns 11 are inserted into the lifting plate 3 and the lifting plate 3 can lift along the guide columns 11.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
