Description
Technical field
The utility model relates to machine field, refers to a kind of motor rotor core dislocation device especially.
Background technology
Composite stepper motor rotor is made up of major parts such as rotor core, rotating shaft, magnet steel, and rotor must stagger between every adjacent rotor iron core an angle, and angular dimension is the half of often adjacent two bottom angles on rotor punching.And rotor only relies on naked eyes to be difficult to the precision of precise control in the fabrication process, once the angular error staggered is larger, just have a strong impact on motor to be in operation and to exert oneself, cause output drop, motor running noises is large, the generation of energy imbalance, even motor is scrapped, and reduces rate of finished products, improves production cost.Publication number is that the Chinese patent of 202798371U discloses a kind of motor rotor core dislocation frock, adjacent rotor core can stagger an angle by this device easily, but rotor concave station must be set to dismountable two halves could be taken out rotor, and this adds workload undoubtedly.
Utility model content
The utility model proposes a kind of motor rotor core dislocation device, adjacent rotor core can to stagger when assembling an angle by this device easily, and when assembling completes and can be taken out by rotor easily.
The technical solution of the utility model is achieved in that a kind of motor rotor core dislocation device, in order to the first rotor iron core adjacent in the rotating shaft of rotor and the dislocation of the second rotor core are assembled, it is characterized in that, comprise cylinder, described cylinder bottom is provided with the first location plug-in unit matched with the inter-tooth slots of the first rotor iron core, described cylinder top is provided with the second location plug-in unit matched with the inter-tooth slots of the second rotor core, described second location plug-in unit may contract among cylinder inner wall, described first location plug-in unit and the second location plug-in unit are provided with dislocation angle.
Further, be provided with a spring in described cylinder inner wall, described second location plug-in unit is connected with described spring and is connected with the spreader that reaches cylinder outer wall, and described spreader end is connected with block.
Further, also slide block is provided with at cylinder outer wall above described cylinder outer wall block.
The beneficial effects of the utility model are: after adopting the motor rotor core dislocation device of this structure, can be staggered adjacent rotor core when assembling an angle easily, because the second location plug-in unit may contract in cylinder inner wall, so can be taken out by rotor easily.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1 to Fig. 3, a kind of motor rotor core dislocation device, in order to assembling that the first rotor iron core 7 adjacent in the rotating shaft of rotor and the second rotor core 8 are misplaced, it is characterized in that, comprise cylinder 1, described cylinder 1 bottom is provided with the first location plug-in unit 3 matched with the inter-tooth slots 9 of the first rotor iron core 7, described cylinder 1 top is provided with the second location plug-in unit 6 matched with the inter-tooth slots 9 of the second rotor core 8, described second location plug-in unit 6 may contract among cylinder 1 inwall, and described first location plug-in unit 3 and the second location plug-in unit 6 are provided with dislocation angle.
Further, be provided with a spring 5 in described cylinder 1 inwall, described second location plug-in unit 6 is connected with described spring 5 and is connected with the spreader 4 that reaches cylinder 1 outer wall, and described spreader 4 end is connected with block 2.
Further, slide block 10 is also provided with at cylinder 1 outer wall above described cylinder 1 outer wall block 2.
The utility model when in use process is as follows: be first fixedly installed on by the first rotor iron core 7 (being generally be fixed on rotating shaft iron core shelves by rotor core by anaerobism glue) in rotating shaft, after fixedly completing, then rotating shaft is put among this motor rotor core dislocation device, the process put into, first outwards hold block 2, be stuck between block 2 and cylinder 1 outer wall when slide block 10 can be used after pulling open, make it can not stop the movement of the first rotor iron core 7, then make the inter-tooth slots 9 of the first location plug-in unit 3 and the first rotor iron core 7 match; Pull out slide block 10 subsequently, the second location plug-in unit 6 is allowed to eject, along the position of the second location plug-in unit 6, second rotor core 8 is put into, after having put into, the first rotor iron core 7 and the second rotor core 8 will stagger an angle, now again anaerobism glue is set between the second rotor core 8 and rotating shaft, makes it fix, after fixing, again the second location plug-in unit 6 is reduced among cylinder 1 inwall, whole rotor is taken out.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
