[0037] At present, the manufacturing process of stator coils is complicated, and the quality of the finished stator coils has a great impact on the quality of motor products. The cold pressing of the coil is the last step in the stator coil manufacturing process. Whether the cold pressing can meet the quality requirements is crucial to the quality of the whole machine. The existing cold pressing of stator coils usually adopts a single-sided forming process, which requires manual holding of one side of the stator coil to cold press the other side of the stator coil. During the cold pressing process, the front and back sides of the stator coil need to be cold pressed separately, which requires a long time and low efficiency.

[0038] In view of this, the utility model provides a stator coil shaping device, which aims to solve the problem that the existing stator coil unilateral shaping method is time-consuming and inefficient.

[0040] In the technical solution of the utility model, the mounting frame 1 is provided so as to install the clamping assembly 2, and the two clamping structures 21 are provided to correspond to the two side edges of the stator coil 200 so as to clamp the two side edges of the stator coil 200 at the same time, and the movable clamping part 211 is movable so as to enable the two clamping parts to clamp the corresponding side edges of the stator coil 200 so as to perform cold pressing on the corresponding side edges of the stator coil 200. Thus, by providing the clamping structure 21, the stator coil shaping device 100 can perform cold pressing and shaping on the corresponding side edges of the stator coil 200, and by providing the two clamping structures 21, the stator coil shaping device 100 can perform cold pressing and shaping on the two side edges of the stator coil 200 at the same time, thereby solving the problem that the existing single-side forming method of the stator coil 200 is time-consuming and inefficient.

[0041] It should be noted that when the shaping coil of the stator coil 200 shapes the two sides of the stator coil 200, the front and back sides of the two sides may be the same or different. For example, both sides may be the front side at the same time, or the back side at the same time, or one side may be the front side and the other side may be the back side. The present invention does not limit this.

[0042] In order to enable the clamping structure 21 to clamp the side of the stator coil 200, in this embodiment, the movable clamping portion 211 is rotatably mounted on the mounting frame 1 along an axis extending horizontally, so that the spacing between the two clamping portions can be adjusted by rotating the movable clamping portion 211, so that the clamping structure 21 can clamp the side of the stator coil 200. Of course, in other embodiments, the movable clamping portion 211 can also clamp the stator coil 200 along a straight line, etc., and the utility model does not limit this.

[0044] In some embodiments of the utility model, the clamping structure 21 further includes a rotating member 212 and a first linear driving structure 213, the middle part of the rotating member 212 is rotatably mounted on the mounting frame 1 along an axis extending horizontally, one end of the rotating member 212 is hinged to the movable clamping portion 211, and the first linear driving structure 213 has a first driving end and a first fixed end opposite to each other, the first driving end is hinged to the other end of the rotating member 212, and the first fixed end is mounted on the mounting frame 1, so that the first linear driving structure 213 is provided to drive one end of the rotating member 212 to rotate, and the rotating member 212 is provided to convert the linear movement of the first linear driving structure 213 into rotation, so that the first linear driving structure 213 can drive the rotating member 212 to rotate, so as to drive the movable clamping portion 211 to rotate and clamp the stator coil 200. Of course, there are many ways to drive the movable clamping portion 211 to rotate. In other embodiments, the movable clamping portion 211 can also be driven by a motor, etc., which is not limited by the utility model. It is understandable that the first linear driving structure 213 may be a driving cylinder or a driving oil cylinder, etc., and the present invention does not limit this.

[0046] In some embodiments of the utility model, the clamping portion is provided with a clamping groove 2113 for installing the stator coil 200. Thus, by providing the clamping groove 2113, it is convenient to place the stator coil 200, and the clamping portion can be completely fitted with the side of the stator coil 200, thereby helping to improve the cold pressing shaping effect of the clamping structure 21. Furthermore, the clamping groove 2113 has a variety of shapes, for example, the clamping groove 2113 can be L-shaped or arc-shaped, etc., and the utility model does not limit this. Specifically, in this embodiment, the clamping groove 2113 is L-shaped, so that the clamping groove 2113 can be adapted to the shape of the stator coil 200, thereby helping the clamping structure 21 to clamp and shape the side of the stator coil 200.

[0047] Furthermore, since different stator coils 200 have different shapes of their sides, in this embodiment, please refer to Figure 1 and Figure 4The clamping part includes a positioning clamping part fixedly arranged on the mounting frame 1, and the positioning clamping part includes a clamping body 2111 and a mounting body 2112 detachably mounted on the clamping body 2111, wherein the clamping groove 2113 is arranged on the mounting body 2112. In this way, a detachable connection structure is adopted so that the mounting body 2112 can be replaced as needed, so that the clamping groove 2113 can be adapted to the shape of the stator coil 200, so that the clamping structure 21 can clamp different stator coils 200, thereby helping to improve the versatility of the stator coil shaping device 100. It can be understood that there are many types of detachable connection structures, which can be bolt connection structures, buckle connection structures, etc., and the utility model does not limit this.

[0048] For different stator coils 200, the requirements for the spacing between the two sides of the stator coil 200 during cold pressing are also different. Therefore, in this embodiment, please refer to Figure 1 and Figure 2 The distance between the two clamping structures 21 is adjustable. Thus, by adjusting the distance between the two clamping structures 21, the requirements for the distance between the two sides of the stator coil 200 can be met, so that the stator coil shaping device 100 can simultaneously perform cold pressing shaping on the two sides of the stator coil 200.

[0049] Furthermore, there are many ways to adjust the distance between the two clamping structures 21. For example, the distance between the two clamping structures 21 can be adjusted by adjusting the position of one of the clamping structures 21, or the distance between the two clamping structures 21 can be adjusted by adjusting the positions of the two clamping structures 21 at the same time. The present invention does not limit this. Specifically, in this embodiment, at least one of the two clamping structures 21 is a movable clamping structure 22.

[0050] In some embodiments of the utility model, the position adjustment structure 23 also includes a first guide structure 233, the first guide structure 233 includes a first slide rail and a first slide groove that slide in cooperation with each other, one of the first slide rail and the first slide groove is provided on the movable clamping structure 22, and the other is provided on the mounting frame 1, so that by providing the first slide rail and the first slide groove that cooperate with each other, the movable clamping structure 22 can move in a horizontal straight line, reducing the probability of the movable clamping structure 22 shaking, thereby helping to improve the stability of the movable clamping part 211. Further, two first guide structures 233 are provided, and the two first guide structures 233 are spaced apart on the mounting frame 1 to improve the stability of the movable clamping structure 22.
