Description

Technical Field

[0001] The present invention relates to the technical field of motor processing, in particular to a winding mechanism for winding a stator core. Background Art

[0002] The wound stator core is a relatively special type of motor stator core. Its manufacturing process is to feed the silicon steel sheet coil strip (width equal to the height of the finished core) into a high-speed punching stepper die, and continuously punch out square slots of equal width with single-sided piercing at set gradient intervals. Subsequently, the strip with the punched slots is tightly wound into a cylindrical shape by the winding mechanism, and the initial inner diameter of the winding is determined by the inner circle of the core. During the winding process, the winding mechanism controls the precise alignment of the pierced square slots at the same position of each winding layer. When the outer diameter of the winding reaches the required position of the core, the die cuts off the strip, and then the die stops punching, and the winding mechanism continues to work until the broken end of the strip is wound to just fit tightly against the outer surface of the reel, and then the broken end is welded firmly by an automatic welding gun, finally forming a wound stator core and completing a cycle.

[0003] In the existing wound stator core manufacturing process, there is a problem of inconvenient mold replacement, which results in a lot of time required for mold adjustment when producing different products, reducing production efficiency. Specifically, the existing equipment mostly adopts a complex fixing structure of a bolt-snap combination, and dozens of fasteners need to be manually disassembled. A single mold change takes as long as 30-60 minutes. In addition, the rigid connection between the mold support frame and the platform leads to a lack of adaptive adjustment capability. The position of the support frame needs to be repeatedly adjusted to match the new mold size. In order to solve the above problems, the present invention proposes a winding mechanism for a wound stator core. Summary of the Invention

[0014] Compared with the prior art, the present invention provides a winding mechanism for winding a stator core, which has the following beneficial effects:

[0015] 1. The winding mechanism of the stator core is able to quickly fix the core winding shaft through the coordinated work of the expansion and moving motor, reversing gearbox, bidirectional threaded screw and other components. The mechanical locking pre-fixation between the expansion moving block and the driving rotating plate, combined with the further locking of the extension fixing plate and the fixed plug rod, is simple to operate, greatly shortens the fixing time of the core winding shaft, improves the overall work efficiency, reduces the tedious installation steps and saves manpower and time costs compared with the traditional fixing method.

[0016] 2. Compared with the traditional rigid connection between the mold support frame and the platform, it lacks the ability to adapt to different mold sizes and needs to repeatedly adjust the position of the support frame, which is a cumbersome and time-consuming process. The winding mechanism of the stator core has adaptive adjustment capabilities. During the fixing process, the expansion moving block forms an extrusion force on the core winding shaft towards both ends, and the extension fixing plate cooperates with the annular fixing groove. When the core winding shaft is rotated, the extension fixing plate moves in the hexagonal groove, automatically adapting to the size of the new mold, and finally forming a snap connection with the annular fixing groove. The above-mentioned cooperation method of the expansion block and the annular fixing groove enables molds to accurately match different sizes without the need for manual repeated adjustment of the support frame position, which improves the flexibility and adaptability of the production process.

[0017] 3. The winding mechanism for the stator core, thanks to its unique combination of an extension block (extended fixing plate) and an annular fixing groove, allows for rapid removal and installation when changing molds by simply following specific steps. Compared to traditional rigidly connected mold supports, this significantly reduces the time required for mold changes, enabling faster switching between winding operations of different specifications, improving equipment flexibility and production efficiency.

[0030] Furthermore, a motor-driven lifting device 12 is fixedly connected to the extension base 2 just below the corresponding iron core winding shaft 6. A flattening roller 13 is fixedly connected to the top of the motor-driven lifting device 12. The flattening roller 13 is Y-shaped, and two metal rollers are rotatably connected to the top of the flattening roller 13. The motor-driven lifting device 12 is used to drive the flattening roller 13 to move up and down to adapt to different winding thicknesses and position requirements. The Y-shaped structure of the flattening roller 13 can press the strip material during the winding process to prevent wrinkles or offsets, ensuring that there is no misalignment between the winding layers. The two metal rollers rotatably connected to the top of the flattening roller 13 help reduce friction with the strip material, allowing the strip material to pass more smoothly.

[0031] Furthermore, the convenient fixed base 5 includes a mounting circular plate 14, an expansion and movement motor 15, a counterweight 16, a reversing gearbox 17, and a sliding seat 18. The drive shaft of the winding motor 4 extends to the other side of the stable mounting frame 3 and is fixedly connected to the mounting circular plate 14. One end of the mounting circular plate 14, which is close to the stable mounting frame 3, is fixedly connected to the expansion and movement motor 15, and the other end is fixedly connected to the counterweight 16. One side of the drive shaft of the expansion and movement motor 15 is fixedly connected to the reversing gearbox 17. The reversing gearbox 17 is fixedly plugged into the mounting circular plate 14 and extends to the other side of the mounting circular plate 14. The side of the mounting circular plate 14 away from the stable mounting frame 3 is fixedly connected to the sliding seat 18. The mounting circular plate 14 serves as the basic support component of the convenient fixed base 5 and is used to connect the drive shaft and other components of the winding motor 4. The expansion and movement motor 15 provides power for the movement of the expansion and movement block 20. The counterweight 16 is used to balance the weight of the expansion and support movement motor 15, ensuring uniform force on both sides of the mounting plate 14 and ensuring the stability of the device. The reversing gear box 17 is used to change the rotation direction of the expansion and support movement motor 15 and transmit power to the bidirectional threaded screw 19. The sliding seat 18 provides a moving track and support for the movable base 23 and the expansion and support movement block 20.

[0032] Furthermore, a bidirectional threaded screw 19 is rotatably connected to the sliding seat 18, and one end of the bidirectional threaded screw 19 is fixedly connected to the driving shaft on the side of the reversing gear box 17 away from the expansion movement motor 15. Both ends of the bidirectional threaded screw 19 are threadedly connected to a movable base 23, and the two movable bases 23 are movably clamped in the sliding seat 18. The front side surfaces of the movable bases 23 are fixedly connected to the expansion moving block 20, and the expansion moving block 20 is in the shape of a "7". The upper end of the expansion moving block 20 is fixedly connected with an arc-shaped tooth 22. The bidirectional threaded screw 19 rotates under the drive of the reversing gear box 17, and the threads at both ends of the bidirectional threaded screw 19 enable the two movable bases 23 to move away from or towards each other in the sliding seat 18. The movable base 23 drives the expansion movable block 20 to move. The expansion movable block 20 is used to be clamped in the clamping cavity formed between the driving rotating plate 33 and the connecting circular plate 34 to preliminarily fix the iron core winding shaft 6. The arc-shaped teeth 22 cooperate with the annular teeth 38 to achieve a pre-fixed state of mechanical locking.

[0033] Furthermore, the convenient fixed base 5 also includes a connecting rod 21, a base 24, and a fixed plug rod 25. The annular outer end of the front side of the mounting circular plate 14 is fixedly connected to a plurality of connecting rods 21, and the other end of the plurality of connecting rods 21 is fixedly connected to the base 24. The base 24 is cylindrical and has a circular through groove. The front side of the base 24 is movably connected to six fixed plug rods 25 distributed in an annular pattern and at equal intervals. The inner wall of the base 24 is provided with an annular fixed groove 26. The connecting rod 21 is used to connect the mounting circular plate 14 and the base 24, playing a supporting and fixing role. The base 24 provides an installation position for the fixation of the core winding shaft 6, and its circular through groove is used to place the fitting circular plate 32 and the connecting circular plate 34. The fixed plug rod 25 is used to finally fix the core winding shaft 6 to prevent it from loosening during the winding process. The annular fixed groove 26 cooperates with the extended fixing plate 35 to further enhance the fixing effect of the core winding shaft 6.

[0034] Furthermore, the base 24 has a front cavity 27 and a rear cavity 28 at the front and rear ends corresponding to the annular fixing groove 26, respectively. A clamping seat 29 is rotatably connected to the inner cavity of the rear cavity 28. The two clamping seats 29 are fixedly connected to the back surfaces of the two clamping seats 29. The other ends of the two clamping springs 30 are fixedly connected to the inner wall of the rear cavity 28. The two clamping springs 30 are positioned parallel to each other. One end of the fixed rod 25 is circular and can be movably connected between the two clamping seats 29. A return spring 31 is movably connected to the inner cavity of the front cavity 27 on the side of the expansion and movement motor 15. The front cavity 27 and the rear cavity 28 provide installation space for components such as the fixed rod 25 and the return spring 31. The clamping seat 29, under the action of the clamping spring 30, can clamp and fix the fixed rod 25, ensuring the stability of the fixed rod 25. The clamping spring 30 provides a clamping force for the clamping seat 29, so that the fixed rod 25 can be firmly fixed between the clamping seats 29. The reset spring 31 provides a reset force for the movement of the extension fixing plate 35 during the rotation of the core winding shaft 6, so that the extension fixing plate 35 can fit tightly with the annular fixing groove 26.

[0035] Furthermore, a fitting circular plate 32 is movably inserted into the circular through groove of the base 24, and the fitting circular plate 32 is recessed inward at one end away from the mounting circular plate 14 to form an inner mounting groove, in which six extended fixing plates 35 equidistantly distributed in an annular shape are placed. Six limiting slide grooves 39 equidistantly distributed in an annular shape are provided on the inner wall of the return spring 31, and the limiting slide grooves 39 are all distributed in an inclined shape. The side of the extended fixing plate 35 close to the mounting circular plate 14 is fixedly connected to the limiting rod, and the limiting rod is movably inserted in the limiting slide groove 39, and the other side of the multiple extended fixing plates 35 is fixedly connected to a strip slider 36, and the strip slider 36 is provided with a socket, and the diameter of the socket is larger than the diameter of the circular block at one end of the fixed plug rod 25. The front cavity 27 and the rear cavity 28 provide installation space for components such as the fixed plug rod 25 and the return spring 31. Clamping seat 29, under the action of clamping spring 30, clamps and secures fixed rod 25, ensuring the stability of fixed rod 25. Clamping spring 30 provides clamping force to clamping seat 29, so that fixed rod 25 can be firmly fixed between clamping seat 29. Restoration spring 31 provides restoring force for movement of extension fixing plate 35 during rotation of core winding shaft 6, so that extension fixing plate 35 can fit tightly with annular fixing groove 26.

[0036] Furthermore, a connecting circular plate 34 is fixedly connected to one side of the fitting circular plate 32. A driving rotating plate 33 is movably engaged with the connecting circular plate 34 and the side of the corresponding extended fixed plate 35 in the inner cavity of the fitting circular plate 32, away from the limiting sliding groove 39. A hexagonal groove 37 is provided on one side of the driving rotating plate 33. A plurality of bar sliders 36 are movably engaged in the hexagonal groove 37. A clamping cavity is formed between the driving rotating plate 33 and the inner wall of the connecting circular plate 34. The side of the connecting circular plate 34 away from the fitting circular plate 32 is fixedly connected to the iron core winding shaft 6. The connecting circular plate 34 is used to connect the fitting circular plate 32 and the iron core winding shaft 6. The driving rotating plate 33 cooperates with the bar sliders 36 through the hexagonal groove 37. When the iron core winding shaft 6 rotates, the driving rotating plate 33 remains stationary, allowing the bar sliders 36 to move in the hexagonal groove 37, thereby driving the extended fixed plate 35 to expand outward. The clamping cavity is used to cooperate with the expansion moving block 20 to achieve preliminary fixation of the iron core winding shaft 6.

[0037] Furthermore, an annular tooth 38 is provided on the inner side of the ring of the driving rotating plate 33, and the annular tooth 38 matches the arc-shaped tooth 22. The annular tooth 38 cooperates with the arc-shaped tooth 22 to achieve a pre-fixed state of mechanical locking when the expansion moving block 20 moves, thereby preventing the iron core winding shaft 6 from loosening during the initial fixation.

[0038] Working principle: When the core winding shaft 6 needs to be fixed, since the core winding shaft 6 and the convenient fixing base 5 are integrated, when the core winding shaft 6 needs to be fixed, the fitting circular plate 32 and the connecting circular plate 34 in the convenient fixing base 5 are placed in the circular through groove in the base 24, and the inner wall of the circular through groove of the base 24 is fixedly connected with a supporting tray near one end of the mounting circular plate 14, and the fitting circular plate 32 is placed against the supporting tray. At this time, the mounting inner groove of the fitting circular plate 32 can allow two expansion moving blocks 20 to be plugged in, and then the expansion moving motor 15 is started, and the rotation of the expansion moving motor 15 drives the reversing. The gear box 17 rotates, and the rotational force of the expansion and movement motor 15 is used to drive the bidirectional threaded screw 19 to rotate through the reversing gear box 17. The rotation of the bidirectional threaded screw 19 causes the movable bases 23 located at both ends thereof to move away from each other in the sliding seat 18. The two expansion moving blocks 20 are driven to move by the two movable bases 23, so that the card block at the upper end of the expansion moving block 20 is engaged in the card cavity formed between the driving rotating plate 33 and the connecting circular plate 34. At this time, the arcuate teeth 22 are against the annular teeth 38. In this process, the arcuate teeth 22 and the annular teeth 38 are initially meshed to form a pre-fixed state of mechanical locking.

[0039] The plurality of fixed insert rods 25 are pulled upward so that the circular quick release at one end of the fixed insert rod 25 is released from the clamping seat 29, and then the connecting circular plate 34 and the fitting circular plate 32 are driven to rotate by rotating the iron core winding shaft 6. Since the driving rotating plate 33 is clamped on the inner wall of the connecting circular plate 34, when the connecting circular plate 34 and the fitting circular plate 32 are rotated, the driving rotating plate 33 is clamped on the two arc-shaped teeth 22 and does not rotate. In contrast, the plurality of strip sliders 36 movably clamped in the hexagonal groove 37 are moved in the hexagonal groove 37 under the influence of the inner wall of the hexagonal groove 37 when rotating, so that the extended fixed plate 35 gradually moves outward. At the same time, it moves outward stably under the action of the limiting rod and the limiting slide groove 39. In the case of gradual rotation, The multiple extension fixing plates 35 rotate in the annular fixing groove 26. When the extension fixing plates 35 rotate, they squeeze the fixed rod 25 upwards. Finally, when the socket on the extension fixing plate 35 moves to the bottom of the circular block of the fixed rod 25, the fixed rod 25 moves to the rear cavity 28 under the push of the reset spring 31, and then the multiple fixed rods 25 are inserted into the clamping seat 29. At this time, the fixation is completed. At this time, the core winding shaft 6 is affected by the fitting circular plate 32 and the connecting circular plate 34, and is subject to the squeezing force of the two expansion moving blocks 20 to both ends and the clamping formed by the multiple extension fixing plates 35 and the annular fixing groove 26. At this stage, the synergistic effect of centrifugal expansion and elastic reset realizes the automatic matching of the mold size and closed-loop control of the positioning accuracy. Compared with the traditional rigidly connected mold support frame, the cooperation between the extension block 35 and the annular fixing groove 26 of this device greatly shortens the mold replacement time.

[0040] After the mold is fixed, the winding motor 4 drives the core winding shaft 6 to rotate through the convenient fixed base 5. At the same time, the winding mechanism controls the precise alignment of the square grooves at the same position of each winding layer. The Y-shaped structure of the flattening roller 13 continuously presses the strip material during the winding process to prevent wrinkles or offsets and ensure that there is no misalignment between the winding layers. When the winding outer diameter reaches the set value, the mold cuts the strip material, and the welding head 11 is accurately positioned to the fracture under the drive of the motor-driven lifting device 12 to complete automatic welding. During the welding process, the clamping spring 30 and the reset spring 31 of the fixed plug 25 work together to ensure that the mold remains stable under high-frequency vibration. Finally, the winding mechanism continues to work until the fracture is wound to the outer surface of the drum, and the welding gun completes the sealing welding to form a complete wound stator core.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
