[0002] In the production and manufacturing of high-efficiency explosion-proof motors, as a core component, the processing quality of stator coils directly affects the performance, safety, and service life of the motors. With the continuous improvement of industrial automation, the market demand for high-efficiency explosion-proof motors is increasing day by day, posing higher requirements for the processing accuracy, production efficiency, and specification adaptability of stator coils. A stator coil shaping device with high precision and high adaptability can not only ensure the stable operation of the motor but also reduce production costs.

[0003] When traditional stator coil shaping devices are in processing, they usually pre-set card slots of specific sizes on the placement table, and these card slots are designed according to the common stator coil sizes. When processing stator coils of corresponding specifications, the coils are directly placed into the corresponding card slots for positioning. By setting multiple manually movable positioning blocks and turning screws and other methods to fix the positions of the positioning blocks, it is ensured that the coils remain stable during shaping.

[0004] However, since the card slots are designed according to the common stator coil sizes, they can only adapt to stator coils with pre-designed sizes. Once encountering new specification coils, the device cannot be used for positioning and processing, and the fixing method is relatively cumbersome with poor stability. Summary of the Invention

[0027] The following describes the specific embodiments of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0028] As Figures 1 to 7As shown in the figure, an efficient shaping device for the stator coil of an explosion-proof motor includes a placement table 1, a positioning mechanism, and a shaping mechanism. The positioning mechanism is arranged on the placement table 1. A plurality of sliding grooves 11 are provided at the top of the placement table 1.

A rotary motor 2 is provided at the bottom of the placement table 1. The output end of the rotary motor 2 is connected with a second bevel gear 21. The first bevel gear 13 and the second bevel gear 21 are meshed with each other. A coil body 3 is arranged on the placement table 1. The slider 14 is used to position the circular ring at the center of the coil body 3. The shaping mechanism is used to shape the coil body 3.

[0029] An installation plate 4 is provided at the bottom of the placement table 1. A support frame 5 is provided at the bottom of the installation plate 4. The support frame 5 is fixedly arranged on the ground. The installation plate 4 is slidably arranged on the support frame 5. The rotary motor 2 is fixedly arranged at the bottom of the installation plate 4.

[0030] The bottom of the installation plate 4 is slidably connected with the support frame 5. A second lead screw 52 is rotatably arranged in a moving groove 51 on the support frame 5. A moving block 41 at the bottom of the installation plate 4 is matched with the second lead screw 52. When a stepping motor 53 drives the second lead screw 52 to rotate, the moving block 41 drives the installation plate 4 to move on the support frame 5, so as to realize the position adjustment of the placement table 1; it is convenient to transfer the coil body 3 on the placement table 1 to below the shaping mechanism, making the shaping operation more convenient and efficient, and improving the coherence of the work process.

[0031] The shaping mechanism includes a shaping box 6, a telescopic motor 61, and a shaping plate 62. The shaping box 6 is arranged at the end of the support frame 5. The telescopic motor 61 is arranged at the top of the shaping box 6, and its output end is connected with the shaping plate 62. The shaping plate 62 is used to perform shaping work on the coil body 3.

[0032] The telescopic motor 61 is installed at the top of the shaping box 6. After starting, its output end drives the shaping plate 62 to descend. A positioning ring 64 on the shaping plate 62 is adapted to the circular ring at the center of the coil body 3, ensuring that the shaping plate 62 accurately aligns with the coil body 3; a second shaping cavity 63 performs shaping operations on the top of the winding of the coil body 3; realizing precise shaping of the top of the winding of the coil body 3, improving the shaping quality of the stator coil, and the positioning ring 64 ensures the accuracy of the shaping position.

[0033] The support frame 5 is provided with a moving groove 51, a second lead screw 52 is rotatably arranged in the moving groove 51, a moving block 41 is arranged at the bottom of the mounting plate 4, the moving block 41 is arranged on the second lead screw 52, and a stepping motor 53 is arranged on the side wall of the support frame 5. The output end of the stepping motor 53 is connected to the second lead screw 52. The size of the moving block 41 is adapted to the moving groove 51.

[0034] After the stepping motor 53 is started, the output end drives the second lead screw 52 to rotate in the moving groove 51. The moving block 41 at the bottom of the mounting plate 4 cooperates with the second lead screw 52. As the lead screw rotates, the moving block 41 drives the mounting plate 4 and the placing table 1 to move on the support frame 5. The position of the placing table 1 can be flexibly adjusted, so that the coil body 3 can be accurately moved below the shaping mechanism, facilitating the shaping work, and improving the flexibility and practicability of the device.

[0035] A plurality of first shaping cavities 15 are arranged on the placing table 1, and the first shaping cavities 15 are used for shaping the bottom of the winding of the coil body 3. A plurality of second shaping cavities 63 are arranged at the bottom of the shaping plate 62, and the second shaping cavities 63 are used for shaping the top of the winding of the coil body 3.

[0036] During the shaping process, the first shaping cavities 15 on the placing table 1 shape the bottom of the winding of the coil body 3, and cooperate with the second shaping cavities 63 on the shaping plate 62 to realize the simultaneous shaping of the upper and lower parts of the winding of the coil body 3. The coil body 3 is shaped in all directions, ensuring the overall shape and dimensional accuracy of the coil body 3 and improving the quality of the stator coil. When the shaping plate 62 descends, the second shaping cavity 63 contacts the top of the winding of the coil body 3, and under the push of the telescopic motor 61, the top of the winding is extruded and shaped to make it reach the required shape. The shape of the top of the winding of the coil body 3 is accurately shaped, ensuring that the stator coil meets the design requirements and improving the accuracy and reliability of the shaping.

[0037] A positioning ring 64 is arranged at the bottom of the shaping plate 62, and the size of the positioning ring 64 is adapted to the ring at the center of the coil body 3.

[0038] During the descent of the shaping plate 62, the positioning ring 64 first adapts to the central ring of the coil body 3 to determine the accurate position of the shaping plate 62, providing a reference for subsequent shaping operations. It ensures the accurate relative position between the shaping plate 62 and the coil body 3, avoids shaping deviation, and improves the shaping accuracy and product quality.

[0039] A telescopic block 7 is provided on the top of the slider 14. The telescopic block 7 slides into the slider 14, and a spring 71 is arranged inside the slider 14. One end of the spring 71 is connected to the inside of the slider 14, and the other end is connected to the telescopic block 7. The telescopic block 7 is used to buffer the positioning ring 64.

[0040] During the shaping process, when the shaping plate 62 applies pressure to the coil body 3, the positioning ring 64 transmits the pressure to the telescopic block 7, and the telescopic block 7 compresses the spring 71. Under the elastic action of the spring 71, it plays a buffering role for the positioning ring 64 and the coil body 3; effectively reducing the impact force on the coil body 3 during the shaping process, preventing the coil body 3 from being damaged due to excessive force, and protecting the integrity and performance of the coil body 3.

[0041] The high-efficiency explosion-proof motor stator coil shaping device mainly consists of a placement table 1, a positioning mechanism, and a shaping mechanism. The bottom of the placement table 1 is connected to the support frame 5 through the mounting plate 4. The mounting plate 4 can slide on the support frame 5, and the support frame 5 is fixed to the ground. A chute 11 is provided on the top of the placement table 1, and an installation cavity is provided inside. A first lead screw 12 is rotatably arranged in the installation cavity, and one end of the first lead screw 12 is connected to a first bevel gear 13. The output end of the rotary motor 2 at the bottom of the placement table 1 is connected to a second bevel gear 21, which meshes with the first bevel gear 13. The bottom of the slider 14 is placed on the first lead screw 12, and the top is slidably matched with the chute 11, and is used to position the central ring of the coil body 3. The shaping mechanism includes a shaping box 6, a telescopic motor 61, and a shaping plate 62. The shaping box 6 is arranged at the end of the support frame 5. The telescopic motor 61 is installed on the top of the shaping box 6, and the output end is connected to the shaping plate 62. The shaping plate 62 is provided with a second shaping cavity 63 and a positioning ring 64. In addition, a first shaping cavity 15 is provided on the placement table 1, a telescopic block 7 with a spring 71 is provided on the top of the slider 14, a moving groove 51 is opened on the support frame 5 and a second lead screw 52 is provided, which is driven by a stepping motor 53. The moving block 41 at the bottom of the mounting plate 4 is matched with the second lead screw 52.

[0042] Working principle of the present invention: Place the coil body 3 on the placement table 1, start the rotary motor 2 to drive the second bevel gear 21 to rotate. Through gear meshing, the first bevel gear 13 drives the first lead screw 12 to rotate, and then the slider 14 moves in the chute 11 to position the central ring of the coil body 3. After positioning, start the stepper motor 53 to drive the second lead screw 52 to rotate, so that the mounting plate 4 and the placement table 1 move on the support frame 5, and move the coil body 3 below the shaping mechanism. Then start the telescopic motor 61 to push the shaping plate 62 to descend. The positioning ring 64 on the shaping plate 62 is adapted to the central ring of the coil body 3 to ensure accurate shaping position. The second shaping cavity 63 on the shaping plate 62 shapes the top of the winding of the coil body 3, and the first shaping cavity 15 on the placement table 1 shapes the bottom of the winding, realizing the all-round shaping of the coil body 3. During this process, the telescopic block 7 on the top of the slider 14 plays a buffering role on the positioning ring 64 under the action of the spring 71, avoiding damage to the coil body 3 during the shaping process.

[0043] The above only discloses several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
