Description

Technical Field

[0001] This utility model relates to the field of flat wire stator flaring technology, and in particular to a flat wire stator flaring device. Background Technology

[0002] Flat wire stator is one of the core components of a motor. It consists of stator core, flat copper wire windings and insulation materials. It is widely used in new energy vehicle drive motors, industrial servo motors and other fields. Its windings use rectangular cross-section flat copper wires instead of traditional round wires. By optimizing the conductor arrangement, the slot fill factor is significantly improved, thereby increasing the motor's power density and heat dissipation efficiency.

[0003] A search revealed a Chinese patent publication number: CN219760815U, which discloses a stator flat wire flaring device, comprising an oval-shaped groove rotary table, a servo motor fixedly mounted on the oval-shaped groove rotary table, a fixed plate fixedly mounted in the oval groove in the middle of the oval-shaped groove rotary table, multiple sliding plates evenly mounted on the edge of the fixed plate, and a gripping cylinder fixedly mounted at the end of each of the multiple sliding plates, with a flaring gripper fixedly mounted at the output end of the gripping cylinder. This multi-model stator flat wire flaring device, equipped with a servo motor, is compatible with stators of different diameters and can precisely control the flaring size to ensure consistency. It is compatible with multiple models. The simultaneous flaring with twelve flaring jaws improves flaring efficiency. The oval-groove rotary table makes the mechanism compact and easy to install and use. The use of pins and sliding grooves allows the flaring jaws to retract and extend during the movement of the gripping cylinder, improving efficiency. However, the stator positioning still relies on manual operation. The stator must be manually placed on the fixed plate and aligned with the circular groove, resulting in slow positioning speed and susceptibility to human error. Manual positioning requires visual alignment, making it impossible to guarantee strict coaxiality between the stator and the flaring jaws. Especially when switching between multiple models, frequent adjustments to the reference are necessary, and accumulated operational errors lead to decreased consistency in flaring size, affecting product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flat wire stator flaring device, which aims to improve the problem that the stator positioning process in the prior art still relies on manual operation, resulting in slow positioning speed and easy human error.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flat wire stator flaring device, comprising a fixing frame and a stator body, wherein a drive motor is fixedly connected to the left side of the interior of the fixing frame, a bevel gear is fixedly connected to the output end of the drive motor, a rotating ring is rotatably connected to the interior of the fixing frame, an annular rack is fixedly connected to the bottom of the rotating ring, the top of the bevel gear is meshed with the bottom left side of the annular rack, a plurality of weight sensors are fixedly connected at equal intervals to the top of the rotating ring, a contact head is fixedly connected to the top of each of the plurality of weight sensors, the same annular bracket is fixedly connected to the upper middle part of the outer wall of each of the plurality of weight sensors, a plurality of circular grooves are equidistantly opened at the bottom of the stator body, the size of the plurality of circular grooves corresponds to the size of the plurality of contact heads, and a locking mechanism is provided on the inner bottom of the fixing frame.

[0006] The above technical solution involves a drive motor that rotates a bevel gear, which in turn causes the rotating ring to move in a circular motion via a rack and pinion transmission. The contact head gradually engages with the circular groove at the bottom of the stator body as the rotating ring rotates. A weight sensor monitors the contact pressure in real time and triggers a signal, enabling the stator body to be quickly positioned. This effectively solves the problem of displacement deviation in the flaring process of the stator and significantly improves efficiency compared to traditional manual positioning.

[0007] As a further description of the above technical solution:

[0008] The locking mechanism includes a telescopic rod, a connecting rod, and multiple arc-shaped locking plates. The bottom end of the telescopic rod is fixedly connected to the inner bottom of the fixing frame. The top of the telescopic rod is hinged to the bottom end of the arc-shaped locking plate via a connecting shaft. Both ends of the connecting rod are respectively hinged to the upper and lower connecting shafts. Multiple fixing rods are fixedly connected around the inner bottom of the fixing frame. The top ends of the multiple fixing rods are all fixedly connected to the same fixing ring. The inner side of the fixing ring is hinged to a connecting shaft via a connecting bracket. The other end of the connecting shaft is hinged to the outer bottom of the arc-shaped locking plate. The outer top ends of the multiple arc-shaped locking plates are respectively engaged around the inner top of the stator body.

[0009] The above technical solution involves extending the telescopic rod upwards, which drives the first connecting shaft and the connecting rod to move. Since the second connecting shaft is limited by the fixing ring, the arc-shaped clamping plate rotates around the second connecting shaft and expands radially. Its top end approaches and contacts the inner wall of the stator body. After reaching the preset position, the telescopic rod stops, and the arc-shaped clamping plate elastically deforms to generate a clamping force. This achieves the synchronous expansion and contraction of the arc-shaped clamping plate, ensuring reliable locking and unlocking of the stator body, avoiding lateral clamping damage, and ensuring the stability of the stator body's position during the locking process.

[0010] As a further description of the above technical solution:

[0011] Multiple L-shaped connecting plates are fixedly connected at equal intervals around the top outer perimeter of the rotating ring. Two ball bearings are rotatably connected to the bottom of each of the multiple L-shaped connecting plates. Two annular grooves are formed on the top of the fixing frame.

[0012] The above technical solution connects the rotating ring to the fixed frame with an L-shaped connecting plate. The balls at the bottom of the plate cooperate with the annular groove at the top of the fixed frame, which enables the rotating ring to rotate with low friction while bearing radial load, ensuring the stable rotation of the stator body during the flaring process.

[0013] As a further description of the above technical solution:

[0014] A control gate is fixedly connected to the front side of the fixed frame. The control gate is electrically connected to the drive motor, multiple weight sensors and the telescopic rod.

[0015] Through the above technical solution, the control gate can control the drive motor, weight sensor and telescopic rod through electrical connection, and control these components to perform corresponding operations.

[0016] As a further description of the above technical solution:

[0017] The fixing frame is fixedly connected to multiple fixing feet at equal intervals around its outer perimeter, and each fixing foot has a fixing hole at its top.

[0018] The above technical solution involves fixing the entire device to the workbench surface with the fixing feet through fixing holes. The equidistant distribution design ensures uniform force distribution, effectively reduces equipment vibration, and guarantees the stability of the stator body during positioning and flaring.

[0019] As a further description of the above technical solution:

[0020] The outer side of the fixing frame adopts a tapered design, and the bottom of the fixing frame adopts an anti-slip design.

[0021] Through the above technical solution: the conical outline of the fixed frame makes it easy for operators to quickly align the installation position, and the anti-slip design at the bottom can increase the friction with the worktable, prevent the equipment from shifting under high-frequency vibration conditions, and improve processing safety.

[0022] As a further description of the above technical solution:

[0023] The dimensions of the multiple arc-shaped clamps are matched with the inner dimensions of the stator body, and the exterior of the multiple arc-shaped clamps are all treated with a frosted finish.

[0024] The above technical solution achieves the following: the arc-shaped clamping plate matches the inner dimensions of the stator body, and the frosted surface increases the contact friction, ensuring that the stator body does not slip circumferentially during the flaring process, while avoiding scratches caused by direct contact between metal surfaces.

[0025] As a further description of the above technical solution:

[0026] The outer surfaces of all the contact heads are rounded, and the outer surface of the annular bracket is chamfered.

[0027] Through the above technical solutions: the smooth curved surface of the contact head can reduce the stress concentration in contact with the stator circular slot, prevent slot deformation, and the chamfered design of the annular bracket facilitates the quick placement and removal of the stator body, avoiding edge collisions.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the drive motor drives the bevel gear to rotate, and the ring rack transmission causes the rotating ring to generate circumferential motion. The contact head gradually engages with the circular groove at the bottom of the stator body as the rotating ring rotates. The weight sensor monitors the contact pressure in real time and triggers a signal to enable the stator body to complete rapid positioning, effectively solving the displacement deviation problem of the stator in the flaring process, and greatly improving the efficiency compared with traditional manual positioning.

[0030] 2. In this utility model, the telescopic rod extends upward, driving the connecting shaft one and the connecting rod to move. Since the connecting shaft two is limited by the fixing ring, the arc-shaped clamping plate rotates around the connecting shaft two and expands radially. Its top end approaches and contacts the inner wall of the stator body. After reaching the preset position, the telescopic rod stops, and the arc-shaped clamping plate elastically deforms to generate a clamping force, realizing the synchronous expansion and contraction of the arc-shaped clamping plate. This ensures reliable locking and unlocking of the stator body, avoids lateral clamping damage, and also ensures the stability of the stator body's position during the locking process.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a flat wire stator flaring device, including a fixing frame 1 and a stator body 10. A drive motor 3 is fixedly connected to the left side inside the fixing frame 1. A bevel gear 4 is fixedly connected to the output end of the drive motor 3. A rotating ring 5 is rotatably connected inside the fixing frame 1. A ring rack 6 is fixedly connected to the bottom of the rotating ring 5. The top of the bevel gear 4 is meshed with the bottom left side of the ring rack 6. Multiple weight sensors 7 are fixedly connected at equal intervals to the top of the rotating ring 5. A contact head 8 is fixedly connected to the top of each of the multiple weight sensors 7. The same ring bracket 9 is fixedly connected to the upper middle part of the outer wall of each of the multiple weight sensors 7. Multiple circular grooves 11 are equidistantly opened at the bottom of the stator body 10. The size of the multiple circular grooves 11 corresponds to the size of the multiple contact heads 8. A locking mechanism 2 is provided on the bottom inner side of the fixing frame 1.

[0040] Specifically, a drive motor 3 is fixedly connected to the left side of the inner interior of the fixed frame 1. The drive motor 3 is a high-precision servo motor, which can provide stable and controllable rotational power. A bevel gear 4 is fixedly connected to the output end of the drive motor 3. A rotating ring 5 is rotatably connected inside the fixed frame 1. The rotating ring 5 adopts a double bearing support structure to ensure rotational accuracy. A ring rack 6 is fixedly connected to the bottom of the rotating ring 5. The ring rack 6 and the bevel gear 4 form a vertical meshing transmission structure. The top of the bevel gear 4 is meshed with the bottom left side of the ring rack 6. The rotational motion of the drive motor 3 is converted into the circular motion of the rotating ring 5 through gear and rack transmission. Multiple weight sensors 7 are fixedly connected at equal intervals to the top of the rotating ring 5. The weight sensors 7 are pressure-sensitive elements that can monitor the contact pressure in real time. The tops of the multiple weight sensors 7... Each end is fixedly connected to a contact head 8. The same annular bracket 9 is fixedly connected to the upper part of the outer wall of multiple weight sensors 7. The annular bracket 9 enhances the structural stability through rigid connection. Multiple circular grooves 11 are equally spaced at the bottom of the stator body 10. The bottom of the grooves 11 and the contact heads 8 form a locking structure. The size of the multiple circular grooves 11 corresponds to the size of the multiple contact heads 8, which can achieve precise positioning. During operation, the drive motor 3 starts and drives the bevel gear 4 to rotate. Through the meshing transmission with the annular rack 6, the rotating ring 5 produces a circular motion. The contact head 8 on the rotating ring 5 gradually approaches the circular groove 11 of the stator body 10 as it rotates. When the contact head 8 enters the circular groove 11, the weight sensor 7 detects the pressure change, which can achieve the initial fixation of the stator body 10, which can significantly improve the efficiency during production.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The locking mechanism 2 includes a telescopic rod 201, a connecting rod 203, and multiple arc-shaped clamping plates 204. The bottom end of the telescopic rod 201 is fixedly connected to the inner bottom of the fixing frame 1. The top of the telescopic rod 201 is hinged to the bottom end of the arc-shaped clamping plate 204 through a connecting shaft 1 202. The two ends of the connecting rod 203 are respectively hinged to the upper and lower connecting shafts 1 202. Multiple fixing rods 208 are fixedly connected around the inner bottom of the fixing frame 1. The top of each of the multiple fixing rods 208 is fixedly connected to the same fixing ring 205. The inner side of the fixing ring 205 is hinged to the connecting shaft 207 through a connecting bracket 206. The other end of the connecting shaft 207 is hinged to the outer bottom of the arc-shaped clamping plate 204. The outer tops of the multiple arc-shaped clamping plates 204 are respectively engaged around the inner top of the stator body 10.

[0042] Specifically, the bottom end of the telescopic rod 201 is fixed to the inner bottom of the fixed frame 1, and its top is hinged to the bottom end of the arc-shaped clamping plate 204 via a connecting shaft 202. Both ends of the connecting rod 203 are hinged to the upper and lower connecting shafts 202 respectively, forming a movable linkage transmission structure. The top ends of the fixed rods 208 around the bottom of the fixed frame 1 are connected to a fixing ring 205. The inner side of the fixing ring 205 is hinged to a connecting shaft 207 via a connecting bracket 206. The other end of the connecting shaft 207 is hinged to the outer bottom of the arc-shaped clamping plate 204. When the telescopic rod 201 is driven to extend upwards, it drives the bottom end of the arc-shaped clamping plate 204 to rise synchronously via the connecting rod 203. Because the connecting shaft 207 is limited by the fixing ring 205, the arc-shaped clamping plate 204 rotates around the connecting shaft 207 and expands radially. At this time, the top end of the arc-shaped clamping plate 204 gradually approaches the fixed shaft 204. Inside the stator body 10, when it contacts the preset position, the telescopic rod 201 stops moving, and the arc-shaped clamping plate 204 generates a clamping force through its own elastic deformation. The serrated structure at its top and the grooves around the top of the stator body 10 achieve circumferential locking. At the same time, the support structure formed by the connecting rod 203 and the connecting shaft 202 provides axial positioning. The four-bar linkage ensures that the four arc-shaped clamping plates 204 expand synchronously. The length design of the connecting rod 203 ensures that the radial displacement of each clamping plate is consistent. The fixing ring 205 and the fixing rod 208 form a rigid frame to ensure the positional stability of the stator body 10 during the locking process. When it is necessary to unlock, the telescopic rod 201 retracts, and the stator body 10 can be removed freely. The mechanical limit ensures the accuracy of repeated positioning and avoids damage to the stator body 10 caused by lateral clamping and fixing.

[0043] Reference Figure 1 , Figure 2 and Figure 4 Multiple L-shaped connecting plates 12 are fixedly connected at equal intervals around the top outer perimeter of the rotating ring 5. Two ball bearings 13 are rotatably connected to the bottom of each L-shaped connecting plate 12. Two annular grooves 14 are opened on the top of the fixing frame 1. A control gate 15 is fixedly connected to the front side of the fixing frame 1. The control gate 15 is electrically connected to the drive motor 3, multiple weight sensors 7, and telescopic rod 201. Multiple fixing feet 16 are fixedly connected at equal intervals around the outer perimeter of the fixing frame 1. Fixing holes 17 are opened on the top of each fixing foot 16. The outer perimeter of the fixing frame 1 adopts a conical design, and the bottom of the fixing frame 1 adopts an anti-slip design. The dimensions of multiple arc-shaped clamping plates 204 match the inner dimensions of the stator body 10. The outer perimeter of multiple arc-shaped clamping plates 204 adopts a frosted process. The outer perimeter of multiple contact heads 8 adopts a smooth design, and the outer perimeter of the annular bracket 9 adopts a chamfered design.

[0044] Specifically, the L-shaped connecting plate 12 connects the rotating ring 5 to the fixed frame 1. The ball bearing 13 at its bottom engages with the annular groove 14 at the top of the fixed frame 1, enabling low-friction rotation of the rotating ring 5 while simultaneously bearing radial loads, ensuring stable rotation of the stator body 10 during the flaring process. The control gate 15, electrically connected to the drive motor 3, weight sensor 7, and telescopic rod 201, controls these components to perform corresponding operations. The fixing feet 16 rigidly fix the entire device to the workbench surface through fixing holes 17. Their equidistant distribution design ensures uniform force distribution, effectively reducing equipment vibration and guaranteeing the stability of the stator body 10 during positioning and flaring processes. The conical outline of the stator 1 facilitates quick alignment of the installation position by the operator. The anti-slip design at the bottom increases the friction with the worktable, preventing displacement of the equipment under high-frequency vibration conditions and improving processing safety. The arc-shaped clamping plate 204 matches the inner dimensions of the stator body 10, and the frosted surface increases the contact friction, ensuring that the stator body 10 does not slip circumferentially during the flaring process, while avoiding scratches caused by direct contact between metal surfaces. The smooth curved surface of the contact head 8 reduces the stress concentration of contact with the stator circular groove 11, preventing groove deformation. The chamfered design of the annular bracket 9 facilitates the quick placement and removal of the stator body 10 and avoids edge collisions.

[0045] Working principle: A drive motor 3 is fixedly connected to the left side of the inner side of the fixed frame 1. The drive motor 3 is a high-precision servo motor, which can provide stable and controllable rotational power. A bevel gear 4 is fixedly connected to the output end of the drive motor 3. A rotating ring 5 is rotatably connected inside the fixed frame 1. The rotating ring 5 adopts a double bearing support structure to ensure rotational accuracy. A ring rack 6 is fixedly connected to the bottom of the rotating ring 5. The ring rack 6 and the bevel gear 4 form a perpendicular meshing transmission structure. The top of the bevel gear 4 is meshed with the bottom left side of the ring rack 6. The rotational motion of the drive motor 3 is converted into rotational motion through the gear and rack transmission. The rotating ring 5 rotates in a circular motion. Multiple weight sensors 7 are fixedly connected at equal intervals to the top of the rotating ring 5. The weight sensors 7 use pressure-sensitive elements to monitor the contact pressure in real time. Contact heads 8 are fixedly connected to the top of each of the multiple weight sensors 7. The same ring bracket 9 is fixedly connected to the upper part of the outer wall of each of the multiple weight sensors 7. The ring bracket 9 enhances the structural stability through rigid connection. Multiple circular grooves 11 are opened at equal intervals at the bottom of the stator body 10. The bottom of the grooves 11 and the contact heads 8 form a locking structure. The size of the multiple circular grooves 11 corresponds to the size of the multiple contact heads 8 to achieve precise positioning.

[0046] Furthermore, the top of the telescopic rod 201 is hinged to the bottom of the arc-shaped clamping plate 204 via a connecting shaft 202, and both ends of the connecting rod 203 are hinged to the upper and lower connecting shafts 202 respectively, forming a movable linkage transmission structure. The top of the fixing rods 208 around the bottom of the fixing frame 1 is connected to a fixing ring 205, and the inner side of the fixing ring 205 is hinged to the connecting shaft 207 via a connecting bracket 206. The other end of the connecting shaft 207 is hinged to the bottom of the outer side of the arc-shaped clamping plate 204. When the telescopic rod 201 is driven to extend upward, the bottom of the arc-shaped clamping plate 204 rises synchronously through the connecting rod 203. Since the connecting shaft 207 is limited by the fixing ring 205, the arc-shaped clamping plate 204 rotates around the connecting shaft 207. The rotation generates radial expansion, at which point the top of the arc-shaped clamping plate 204 gradually approaches the inner side of the stator body 10. When it contacts the preset position, the telescopic rod 201 stops moving, and the arc-shaped clamping plate 204 generates a clamping force through its own elastic deformation. The serrated structure at its top and the grooves around the top of the inner side of the stator body 10 achieve circumferential locking. At the same time, the support structure formed by the connecting rod 203 and the connecting shaft 202 provides axial positioning. The four-bar linkage ensures that the four arc-shaped clamping plates 204 expand synchronously. The length design of the connecting rod 203 ensures that the radial displacement of each clamping plate remains consistent. The fixing ring 205 and the fixing rod 208 form a rigid frame to ensure the positional stability of the stator body 10 during the locking process.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
