Description

Technical Field

[0001] This utility model relates to the field of motor stator technology, specifically to a motor stator coil shaping device. Background Technology

[0002] The stator of a motor consists of an iron core and coils wound around the iron core. Because the coils exposed above and below the iron core are irregularly shaped, it is not conducive to the installation of the rotor when the stator is installed. Therefore, the iron core must be shaped after each coil is wound.

[0003] Chinese Patent No. CN216959598U discloses a motor stator coil shaping device, specifically relating to the field of motor stators. The device includes a chassis with multiple inner shaping plates arranged in a circular array on the top of the chassis. These inner shaping plates are slidably connected to the chassis. An inner drive mechanism is located at the bottom of each inner shaping plate. Corresponding outer shaping plates are arranged on the outer sides of the inner shaping plates, and these outer shaping plates are slidably connected to the chassis. An outer drive mechanism is located at the bottom of each outer shaping plate. The inner drive mechanism includes multiple inner sliding plates radially distributed about the center of the chassis. These inner sliding plates are located at the bottom of the inner shaping plates and are fixedly connected to them. An inner drive plate is located at the bottom of each inner sliding plate. This invention uses a worm gear and worm shaft to drive an internal gear and an external gear ring to rotate, thereby causing the inner and outer drive mechanisms to move the inner and outer shaping plates to clamp the coil, shaping the outer ring of the inner coil.

[0004] However, in the above technical solution, the internal gear and external gear ring are driven to rotate by setting a worm gear and worm shaft, so that the internal drive mechanism and the external drive mechanism drive the internal shaping plate and the external shaping plate to clamp the coil and shape the outer ring of the inner ring of the coil. However, this structure relies on the precise cooperation of multiple transmission components such as worm gear, worm shaft, internal gear, and external gear ring. The long transmission chain leads to an increase in accumulated error, making it difficult to ensure the absolute synchronization of the movement of all internal and external shaping plates. Slight asynchrony will cause shearing force to be generated on the coil during the shaping process, which can easily scratch or even cut the insulation layer of the wire, causing fatal inter-turn short circuit.

The frame 1 is connected to the first telescopic device 2. The first telescopic device 2 is selected from, but is not limited to, a hydraulic cylinder, which is connected to hydraulic equipment provided in the factory. The telescopic end of the first telescopic device 2 is connected to the connecting frame 3. The connecting frame 3 is composed of a plate and multiple rods, and there is a gap between the plate and the mounting plate 4 to accommodate the upper mold 5. The mounting plate 4 is connected to the connecting frame 3. The frame 1 consists of a base plate 13, a top plate 14 and support rods 15. The two ends of the multiple support rods 15 are respectively connected to the base plate 13 and the top plate 14, and the first telescopic device 2 is connected to the top plate 14. The frame 1 is connected to symmetrically arranged positioning rods 16. The two ends of the positioning rods 16 are connected to the top plate 14 and the bottom plate 13 respectively. The mounting plate 4 is slidably sleeved on the outside of the positioning rods 16. The positioning rods 16 serve as guides. A self-lubricating sleeve is installed on the positioning rods 16 to reduce wear. The sleeve is connected to the mounting plate 4. There are two shaping components, which are set on the frame 1 and the mounting plate 4. The shaping components are connected to the upper mold 5 and the lower mold 6. The shaping components include a second telescopic device 11 and an adjusting plate 12. The telescopic end of the second telescopic device 11 is connected to the frame 1 or the mounting plate 4. The second telescopic device 11 is selected from, but is not limited to, a hydraulic cylinder, which is connected to the hydraulic equipment provided in the factory. The telescopic end of the second telescopic device 11 is connected to the adjusting plate 12. The adjusting plate 12 has a guide groove with a V-shaped cross section. The guide groove has an inclined surface that contacts the inner shaping plate 7 and the outer shaping plate 8, pushing them to slide along the guide rod 9 and move closer to each other.

[0017] Example 2, as Figures 2-4 As shown, the present invention proposes a motor stator coil shaping device. Compared with Embodiment 1, this embodiment describes the detailed structure of the mold body. The main body of the mold consists of an upper mold 5 and a lower mold 6. The upper mold 5 and the lower mold 6 have the same structure. The upper mold 5 and the lower mold 6 are respectively connected to the mounting plate 4 and the frame 1. The upper mold 5 consists of multiple inner shaping plates 7, outer shaping plates 8, guide rods 9 and mounting base 10 arranged in a circular array. The mounting base 10 has a cavity for receiving. Multiple guide rods 9 arranged in a circular array are connected in the cavity for receiving. Each guide rod 9 is provided with an inner shaping plate 7 and an outer shaping plate 8. The multiple inner shaping plates 7 and outer shaping plates 8 form a hollow cylindrical cavity for receiving. Both the inner shaping plate 7 and the outer shaping plate 8 are composed of an arc plate 17 and a sliding block 18. The sliding block 18 is slidably sleeved on the guide rod 9. The arc plate 17 is connected to the sliding block 18. The diameters of the arc plates 17 of the inner shaping plate 7 and the outer shaping plate 8 are different. When the arc plates 17 are spliced ​​together, they form a hollow cylinder to fit against the inner or outer wall of the coil for shaping. A support shaft is connected to the sliding block 18, and a roller 19 is rotatably connected to the support shaft. The roller 19 contacts the inclined surface of the guide groove. The roller 19 can reduce friction with the adjustment plate 12 and prevent subsequent movement from being unsmooth due to friction. An elastic element 20 is connected between the sliding blocks 18 of the inner shaping plate 7 and the outer shaping plate 8. The elastic element 20 is sleeved on the outside of the guide rod 9. The elastic element 20 is a spring. The setting of the elastic element 20 can make the two sliding blocks 18 quickly reset after losing external force, so as to facilitate the removal of the workpiece. Both the inner shaping plate 7 and the outer shaping plate 8 have elastic buffer pads connected to the side that contacts the coil. The elastic buffer pads are made of, but are not limited to, rubber, which can reduce the pressure of the arc plate 17 in the inner shaping plate 7 and the outer shaping plate 8 on the coil and prevent it from affecting its performance. The mounting base 10 consists of a fixed base 21 and a cover plate 22. The fixed base 21 is connected to the base plate 13 or the mounting plate 4. The cover plate 22 is detachably connected to the fixed base 21 by bolts. A cylindrical receiving cavity is formed between the cover plate 22 and the fixed base 21. The cover plate 22 is easy to disassemble for maintenance of the internal structure of the receiving cavity.

[0018] In summary, when using this utility model, the operator places the stator coil inside the lower mold 6 on the outside of the shaping plate 7. After starting the device or control equipment, the first telescopic device 2 moves the connecting frame 3 and the mounting plate 4 downwards. The mounting plate 4 moves vertically along the positioning rod 16 via a self-lubricating sliding sleeve, causing the upper mold 5 to approach the lower mold 6. After moving to the preset position, the first telescopic device 2 stops, and the second telescopic device 11 starts. The second telescopic device 11 moves the adjusting plate 12 vertically, and the inclined plate on the adjusting plate 12... The inner and outer shaping plates 7 and 8 are in contact with the rollers 19 connected to the sliding blocks 18. Under the action of force, the sliding blocks 18 will move along the central axis of the guide rod 9, compressing the length of the elastic element 20, so that the inner and outer shaping plates 7 and 8 are close to the inner and outer walls of the stator coil, thereby shaping. After completion, the second telescopic device 11 drives the adjusting plate 12 away from the inner and outer shaping plates 7 and 8. The inner and outer shaping plates 7 and 8 rebound and reset under the action of the elastic element 20, releasing the stator coil, which can then be removed by the operator.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
