[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an integrated device for riveting and positioning motor cores, including a workbench 1, a support rod 2 fixedly connected to the upper surface of the workbench 1, a top plate 3 fixedly connected to the upper surface of the support rod 2, a positioning mechanism 4 provided on the upper surface of the workbench 1, and a riveting mechanism 5 provided on the lower surface of the top plate 3.

[0022] The positioning mechanism 4 includes a fixed block 401, a base 402, a motor 403, a threaded rod 404, a helical side toothed block 405, a sliding block 406, a sliding groove 407, a gear 408, a rotating shaft 409, a rotating groove 410, a toothed block 411, a limiting block 412, a limiting plate 413, a moving groove 414, a limiting groove 415, a clamping block 416, and an iron core placement plate 417. The fixed block 401 is fixedly connected to the upper surface of the worktable 1. The base 402 is fixedly connected to the inner surface of the fixed block 401. The motor 403 is fixedly connected to the upper surface of the base 402. A threaded rod 404 is fixedly connected to one end of the motor 403. A helical side toothed block 405 is threadedly connected to the outer surface of the threaded rod 404. The lower surface of the helical side toothed block 405... A sliding block 406 is fixedly connected. A sliding groove 407 is formed on the upper surface of the base 402. A gear 408 meshes with one side surface of the helical-knotted toothed block 405. A rotating shaft 409 is fixedly connected to the lower surface of the gear 408. A rotating groove 410 is formed on the upper surface of the base 402. A toothed block 411 meshes with the upper surface of the helical-knotted toothed block 405. A limiting block 412 is fixedly connected to one side surface of the toothed block 411. A limiting plate 413 is slidably connected to the outer surface of the limiting block 412. A moving groove 414 is formed on the inner surface of the limiting plate 413. A limiting groove 415 is formed on the inner surface of the moving groove 414. A clamping block 416 is fixedly connected to one end surface of the toothed block 411. A core placement plate 417 is fixedly connected to the inner surface of the fixing block 401. Through the arrangement of a fixed block 401, a base 402, a motor 403, a threaded rod 404, a helical side toothed block 405, a sliding block 406, a sliding groove 407, a gear 408, a rotating shaft 409, a rotating groove 410, a toothed block 411, a limiting block 412, a limiting plate 413, a moving groove 414, a limiting groove 415, a clamping block 416, and a core placement plate 417, in use, the motor core is first placed in the center of the core placement plate 417, then the motor 403 is started, driving the threaded rod 404 to rotate. Under the rotation of the threaded rod 404, the helical side toothed block 405 will move linearly along the threaded rod 404, and the sliding block 406 below the helical side toothed block 405 will slide smoothly along the sliding groove 407 on the base 402. A serrated block is provided on one side surface of the helical-patterned toothed block 405. This serrated block meshes with the gear 408. When the helical-patterned toothed block 405 moves linearly, it drives the meshing gear 408 to rotate. The rotating shaft 409 below the gear 408 rotates in the rotating groove 410. The rotation of the gear 408 drives the other two sets of helical-patterned toothed blocks 405 to move. The upper surface of the helical-patterned toothed block 405 is also provided with helical patterns and meshes with the toothed block 411. When the helical-patterned toothed block 405 moves, it pushes the toothed block 411 to move. The limiting block 412 on one side of the toothed block 411 slides in the moving groove 414 of the limiting plate 413. When the toothed block 411 moves, the clamping block 416 moves accordingly. The three sets of clamping blocks 416 move from different directions toward the center position of the iron core placement plate 417.Gradually approaching the motor core, the clamping mechanism 4 clamps and positions the core. Its compact structure and precise positioning ensure improved machining accuracy and quality of the motor core.

[0023] Furthermore, the helical side toothed block 405 forms a sliding structure through the motor 403 and the threaded rod 404. The outer dimension of the sliding block 406 matches the inner dimension of the sliding groove 407. The upper surface of the helical side toothed block 405 is provided with helical lines, and one side surface of the helical side toothed block 405 is provided with serrated blocks. Through the setting of the sliding block 406 and the sliding groove 407, during use, the sliding groove 407 limits the sliding block 406, and the sliding block 406 can only slide along the sliding groove 407, making the movement of the helical side toothed block 405 more stable and the direction more accurate.

[0024] Furthermore, the helical side tooth block 405 has three sets of teeth on the outer surface of the tooth block 411. The outer dimension of the rotating shaft 409 matches the inner dimension of the rotating groove 410. With the arrangement of the rotating shaft 409 and the rotating groove 410, when the helical side tooth block 405 moves and drives the gear 408 to rotate around the rotating shaft 409 during use, the rotating groove 410 can effectively limit the displacement of the rotating shaft 409, so that the gear 408 can only rotate on the predetermined axis, eliminating unstable situations such as shaking or deviation of the gear 408, ensuring the reliability of the entire transmission process, and enabling the power output from the motor 403 to be stably and efficiently transmitted to the clamping block 416.

[0025] Furthermore, the outer dimensions of the limiting block 412 match the inner dimensions of the moving groove 414. Two sets of limiting blocks 412 are symmetrically arranged around the central axis of the toothed block 411. With the setting of the limiting blocks 412, during use, two sets of limiting blocks 412 are symmetrically arranged around the central axis of the toothed block 411. This symmetrical structure can provide balanced support and guidance. The two sets of limiting blocks 412 work together to evenly distribute the force transmitted from the toothed block 405 and other components on the helical side, preventing the toothed block 411 from tilting or deforming due to excessive force on one side, so that the toothed block 411 moves smoothly and steadily.

[0026] Furthermore, the limiting plate 413 is fixedly connected to the fixing block 401, and the clamping block 416 is provided in three sets. With the clamping block 416, during use, the three sets of clamping blocks 416 can move towards the center of the iron core from three different directions at the same time, providing a more uniform and symmetrical clamping force, fixing the motor iron core in all directions, so that the position of the iron core is more accurate and stable in subsequent processing, and greatly improving the product processing quality.

[0027] Furthermore, the riveting mechanism 5 includes a cylinder 501, a lifting plate 502, a riveting block 503, a limiting rod 504, and a limiting post 505. The cylinder 501 is fixedly connected to the lower surface of the top plate 3. The lifting plate 502 is fixedly connected to one end surface of the cylinder 501. The riveting block 503 is fixedly connected to the lower surface of the lifting plate 502. The limiting rod 504 is slidably connected to the inner surface of the riveting block 503. The limiting post 505 is fixedly connected to one end surface of the limiting rod 504. Through the arrangement of the cylinder 501, lifting plate 502, riveting block 503, limiting rod 504, and limiting post 505, when the cylinder 501, lifting plate 502, riveting block 503, limiting rod 504, and limiting post 505 are used, the riveting mechanism 5 can achieve the desired riveting effect. When the positioning mechanism 4 has accurately positioned the motor core on the core placement plate 417, the cylinder 501 is activated. The piston inside the cylinder 501 pushes the lifting plate 502 connected to it to move downward. Since the riveting block 503 is fixed below the lifting plate 502, the riveting block 503 also moves downward synchronously, approaching the motor core to rivet it. During this process, the lifting plate 502 slides along the limit rod 504. The limit rod 504 provides precise guidance for the lifting and lowering movement of the riveting block 503, ensuring that the riveting block 503 can accurately align with the position to be riveted.

[0028] Furthermore, one end of the limiting rod 504 is fixedly connected to the iron core placement plate 417. Multiple sets of limiting rods 504 are provided on the inner surface of the lifting plate 502. The diameter of the limiting post 505 is larger than the diameter of the limiting rod 504. Through the setting of the limiting rods 504, during use, multiple sets of limiting rods 504 ensure that the lifting plate 502 and the rivet block 503 can move in a straight line. The setting of multiple sets of limiting rods 504 improves the stability and accuracy of the movement of the lifting plate 502 and prevents unstable phenomena such as tilting, deviation or shaking during the lifting process.

[0029] Working principle: First, the motor core is placed in the center of the core placement plate 417. Then, the motor 403 is started, driving the threaded rod 404 to rotate. Under the rotation of the threaded rod 404, the helical side tooth block 405 will move linearly along the threaded rod 404. The sliding block 406 below the helical side tooth block 405 slides smoothly along the sliding groove 407 on the base 402. A serrated block is provided on one side surface of the helical side tooth block 405, which meshes with the gear 408. When the helical-patterned toothed block 405 moves linearly, it drives the gear 408 meshing with it to rotate. The rotating shaft 409 below the gear 408 rotates in the rotating groove 410. The rotation of the gear 408 drives the other two sets of helical-patterned toothed blocks 405 to move. The upper surface of the helical-patterned toothed block 405 is also provided with helical patterns and meshes with the toothed block 411. When the helical-patterned toothed block 405 moves, it pushes the toothed block 411 to move. The limiting block 412 on one side of the toothed block 411 moves within the limiting plate 413. The moving slot 414 slides within the moving slot. When the toothed block 411 moves, the clamping block 416 moves accordingly. The three sets of clamping blocks 416 move from different directions toward the center of the iron core placement plate 417, gradually approaching the motor iron core to clamp and position it. The positioning mechanism 4 has a compact structure and precise positioning, which provides a guarantee for improving the processing accuracy and quality of the motor iron core. Then, the cylinder 501 is activated. The piston inside the cylinder 501 pushes the lifting plate 502 connected to it to move downward. Since the riveting block 503 is fixed below the lifting plate 502, the riveting block 503 also moves downward synchronously, approaching the motor iron core to rivet it. During this process, the lifting plate 502 slides along the limiting rod 504. The limiting rod 504 provides precise guidance for the lifting and lowering movement of the riveting block 503, ensuring that the riveting block 503 can accurately align with the position to be riveted, preventing instability such as tilting, offsetting, or shaking during the lifting and lowering process.
