[0002] At present, in the motor manufacturing process, the motor stator coil winding is a very critical component. After the traditional motor stator coil winding is wound, there are often some redundant parts. If these redundant parts are not properly handled, they will affect the performance and quality of the motor.

[0003] In the traditional production process, the excess part of the motor stator coil winding is usually cut manually using tools such as scissors or knives. This method has many disadvantages. First, manual operation is prone to errors, and inconsistent cut lengths may cause some windings to be too long or too short, affecting the electrical performance and operating stability of the motor. Second, manual operation is inefficient, consumes a lot of manpower and time costs, and is difficult to meet the needs of large-scale industrial production.

[0004] In order to solve these problems, there is an urgent need for a special excess part shaping and cutting device for motor stator coil windings, which can accurately and efficiently complete the removal of excess parts, ensure that the length of each winding meets the standard requirements, improve the production quality and efficiency of the motor, reduce the errors and labor intensity caused by manual operation, and adapt to the needs of modern large-scale motor production.

[0014] The present invention provides a device for shaping and removing excess parts of motor stator coil windings. It has the following beneficial effects: 1. The excess part shaping and cutting device for the motor stator coil winding can gather multiple bundles of motor stator coils together for unified excess part shaping and cutting operations through the setting of the opening and closing components. In this way, multiple coils can be processed simultaneously in one processing process, which greatly improves production efficiency, avoids the tediousness and time waste caused by operating each bundle of coils separately, and meets the needs of large-scale production. By closing multiple bundles of coils together and using the opening and closing components for cutting, it can be ensured that each bundle of coils is subjected to relatively consistent operating conditions and parameters when cutting the excess parts, so that the excess part cutting effect of each bundle of coils is highly consistent, ensuring the consistency and stability of product quality. When the motor provides a counterclockwise rotation force, the fixed plate performs an outward opening movement, and the distance between the fixed plates becomes larger, which is convenient for the loading of the coils. When the motor provides a clockwise rotation force, the fixed plate performs an inward closing movement, and the distance between the fixed plates becomes smaller, which is convenient for the unified cutting of multiple bundles of coils.

[0015] 2. The excess part shaping and cutting device for the motor stator coil winding can firmly fix the motor stator coil winding of the excess part to be cut off at a specific position through the setting of the fixing mechanism to prevent the coil winding from moving, shaking or rotating during the cutting process. This is the basis for ensuring that the cutting operation can be carried out accurately. Only when the coil position is fixed can the cutting tool accurately cut off the excess part to avoid cutting errors caused by inaccurate coil position and ensure the cutting quality. The fixing mechanism has a certain adaptability and can adapt to motor stator coils of different sizes. It can be compatible with large and small coils through the elastic force of the support spring, so that the device can be used in different production scenarios, with strong versatility and flexibility. When the operator sets the stator coil on the surface of the first fixed block and the second fixed block, the support spring is compressed to achieve the compatibility of the coil, and then the excess part of the coil is inserted into the locking clamp, and the elastic strip squeezes the coil to achieve the fixation of the excess part of the coil.

[0016] 3. The excess part shaping and cutting device for the motor stator coil winding can be opened and closed in the best way according to the specific shape of the winding by rotating to a suitable angle through the setting of the cutting component, so as to better fit the contour of the coil and realize effective cutting of the excess parts of coils of various shapes, thereby enhancing the adaptability and versatility of the device to coils of different shapes. In the process of rotating opening and closing, the cutting operation of the excess parts of coils in multiple positions can be completed at one time. Compared with the traditional linear cutting method which requires multiple tool movements, the cutting component can cover a wider cutting area in one rotating opening and closing action, greatly reducing the number and time of cutting operations and significantly improving the cutting efficiency. When the rotating shaft rotates counterclockwise, the cutting blade opens outward, and when the rotating shaft rotates clockwise, the cutting blade closes inward, and the cutting blades gradually come into contact to realize the cutting of the excess parts of the coil.

[0017] 4. The excess part shaping and cutting device for the motor stator coil winding has an extrusion mechanism. When the rotating shaft rotates clockwise, the cutting blade gradually contacts the excess coil. At this time, the cylinder is opened, the extrusion block moves downward, and the convex block squeezes the excess coil, so that multiple bundles of coils are at the same cutting height, ensuring the consistency and stability of product quality and improving the overall working efficiency and cutting effect of the device.

[0023] The opening and closing assembly 24 includes a first fixed plate 241, which is fixedly mounted on the outer surface of the rotating shaft 23.

The cutting blade 252 gradually contacts to achieve the cutting of the excess part of the coil.

[0026] The third embodiment is based on the first and second embodiments. Figures 1 to 7 As shown, the fixing mechanism 3 includes a first fixing block 31 and a second fixing block 33.

[0027] The fourth embodiment is based on the second and third embodiments. Figures 1 to 8As shown, the extrusion mechanism 4 is arranged just above the opening and closing cutting mechanism 2, and the extrusion mechanism 4 includes a cylinder 41 and a fixing frame 43.
