[0002] Stator core shaping is the process of machining and adjusting the stator core of the motor to ensure that its shape, size and performance meet the design requirements, thereby improving the accuracy of stator matching and the stability of subsequent operation when the motor is subsequently assembled.

[0003] For example, the utility model patent disclosed in the publication number CN215300432U is a pressing mechanism of a shaping device for a stator core, including a base plate, a support frame, a bracket, a top plate, a cylinder, a guide rod, a lower mold mounting plate and an auxiliary device. The utility model is provided with an auxiliary device installed just behind the base plate, and a push-out mechanism is provided in the auxiliary device. The motor drives the internal pulley transmission to drive the cam to move, so that the front push-out rod pushes the supporting member to contact the stator core and push it into the pressing position, with good automation effect, avoiding damage caused by incorrect position during pressing; a rotating mechanism is provided at the bottom of the pushing mechanism, and the rotating mechanism is driven by an independent motor to drive the internal toothed belt pulley group to move, so that the pushing mechanism is rotated when adjusting the front and rear positions of the stator core, thereby realizing the left and right position adjustment of the stator core, making the pressing position more accurate.

[0025] The transmission device 4 includes a support guide seat 42 , a servo motor 41 is arranged near the middle of the upper end surface of the support guide seat 42 , an open disc 43 is fixedly arranged at the output end surface of the servo motor 41 , and a fixed lever 44 is arranged at the upper end surface of the open disc 43 .

[0026] The material guiding device 5 comprises a guide turntable 54, and eight groups of limit slots 55 are equidistantly provided on the upper end surface of the guide turntable 54 near the edge, and a positioning turntable 53 for positioning is provided on the upper end surface of the guide turntable 54, a transmission groove wheel 52 is provided on the upper end surface of the positioning turntable 53, and eight groups of groove wheel sliding grooves 51 are equidistantly provided on the inner end surface of the transmission groove wheel 52.

[0027] The side end surface of the transmission groove wheel 52 is equidistantly provided with eight groups of clamping grooves, and the clamping grooves are rotationally clamped with the open disk 43. The rotational clamping of the clamping grooves and the open disk 43 can provide sufficient time and limiting basis for the subsequent shaping mold 8 to shape the stator core 2.

[0028] The fixed lever 44 is rotatably engaged with the groove wheel slot 51 , and the shaping mold 8 is coaxially aligned with the stator core 2 , which can effectively improve the accuracy of subsequent shaping of the stator core 2 by the shaping mold 8 .

[0029] The inner wall of the stator core 2 is fitted and connected to the inner wall of the limiting slot 55, and the outer wall of the stator core 2 is fitted and connected to the inner wall of the guide slip ring 6. The guide slip ring 6 and the limiting slot 55 can jointly limit the outside of the stator core 2, which can not only ensure that the stator core 2 is limited inside the guide turntable 54, but also improve the stability of the stator core 2 when guiding.

[0030] Working principle: Before use, the user can position the external loading module to the loading guide plate 1, and then position the unloading module to the second opening of the guide slip ring 6, so as to facilitate the subsequent rapid unloading operation of the stator core 2 after the shaping is completed. When the stator core 2 is cyclically shaped, the external loading module can guide the stator core 2 into the limiting slot 55 through the loading guide plate 1, and then the servo motor 41 is started. The servo motor 41 can synchronously drive the opening disc 43 and the fixed lever 44 to rotate one circle. At this time, the opening disc 43 can be limited with the side of the transmission groove wheel 52. When the opening disc 43 rotates to the transmission groove wheel 52, the opening disc 43 releases the limit on the transmission groove wheel 52, and at the same time, the fixed lever 44 can drive the transmission groove wheel 52 to rotate one-eighth of a circle through the groove wheel slide groove 51, and the cycle is repeated until the stator core 2 inside the limiting slot 55 is positioned to the bottom of the shaping mold 8. At this time, the stamping cylinder 3 can drive the shaping mold 8 to move downward, thereby cooperating with the positioning of the positioning turntable 53 to press and shape the stator core 2. Subsequently, when the shaped stator core 2 rotates to the unloading module, the unloading module can guide the stator core 2 out.
