Description

Technical Field

[0001] This invention relates to the field of winding machines, and more specifically, to a winding device for stator and rotor production. Background Technology

[0002] When manufacturing a rotor, copper wire needs to be wound around the rotor surface. This operation is usually done using a rotor winding machine. The rotor winding machine is a key piece of equipment in motor manufacturing used to wind wound rotors or stator coils. Its function is to wind enameled copper wire into the slots of the rotor core according to a specific pattern and ensure the insulation, symmetry and precision of the winding.

[0003] Chinese patent CN105811689A discloses a rotor winding machine. The tension adjustment frame is also equipped with a knob adjustment wheel, which can perform a second-level adjustment to improve the adjustment accuracy. In addition, the tension adjustment frame of this invention also has a height adjustment function, which can be used by workers of different heights and can also play a certain role in tension adjustment. In short, this device can effectively prevent copper wire from breaking during the winding process.

[0004] While the aforementioned patents effectively prevent copper wire from breaking during the winding process, the winding process relies on pressing the copper wire down onto an arc-shaped guide plate. The copper wire slides onto the guide plate to the winding position on the rotor surface to achieve the winding effect. However, these guide plates can only be used with one type of rotor, resulting in a relatively small range of applications. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a winding device for stator and rotor production. By moving the slider, the guide plate moves up and down, facilitating control of the guide plate's position. The distance between the two guide plates is adjusted according to the rotor's height, ensuring the distance is the same as the rotor's height. This adjustment is tailored to the rotor's dimensions, broadening its applicability. The rotor is moved to the guide plate, positioning the rotor slot between the two guide plates. When the protective mechanism rotates with the copper wire, the copper wire contacts the arc surface of the guide plate. The arc surface guides the copper wire, allowing it to slide to the rotor's position, thus facilitating rotor winding.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A winding device for stator and rotor production includes a frame, a hydraulic cylinder fixedly connected to the top of one side of the frame, a rotating mechanism fixedly connected to the other side of the frame, a protective mechanism provided at the top of the rotating mechanism, and a wire guiding mechanism provided on one side of the frame.

[0008] The wire guiding mechanism includes a cylinder movably connected to the frame, a mounting block fixedly connected to the right side of the cylinder, and a slider slidably connected inside the mounting block.

[0009] Furthermore, a guide plate is slidably connected to the top of the slider, and the slider extends towards the mounting block near the mounting block to form a first extension block. A second groove is provided inside the mounting block corresponding to the position of the first extension block to accommodate the movement of the first extension block. A second spring is welded to the first extension block inside the second groove.

[0010] Furthermore, the mounting block is internally slidably connected to an extrusion rod, and extrusion blocks are fixedly connected to the top and bottom of the extrusion rod. An extrusion groove is provided inside the slider, and the cross-sectional shape of the extrusion groove is a right trapezoid.

[0011] Furthermore, a third limiting block is fixedly connected inside the mounting block, and a fourth spring, welded to the third limiting block, is provided inside the compression rod.

[0012] Furthermore, an arc-shaped plate is fixedly connected to the bottom right side of the guide plate. The contact surface between the arc-shaped plate and the rotor is an arc surface, and the width of the arc-shaped plate is smaller than that of the guide plate.

[0013] Furthermore, the guide plate extends towards the slider from the side near the slider to form a second extension block. A third spring is provided inside the slider and welded to the second extension block. The outer surface of the left side of the cylinder extends to form an outer ring. Multiple mounting holes arranged in a ring array are provided inside the outer ring.

[0014] Furthermore, the protection mechanism includes a connecting rod fixed to the rotating mechanism, a rotating rod rotatably connected to the right side of the connecting rod, and an elastic bead fixedly connected to one end of the rotating rod near the connecting rod.

[0015] Furthermore, a receiving hole is provided on the side of the rotating rod away from the connecting rod, and the elastic bead is a solid iron ball wrapped with rubber.

[0016] Furthermore, a second limiting block is fixedly connected to the rear side of the receiving hole, and a first limiting block is slidably connected to the left side of the second limiting block. A first sliding groove is provided inside the rotating rod to accommodate the movement of the first limiting block.

[0017] Furthermore, an adjusting block is fixedly connected inside the first chute, and a first spring is welded between the adjusting block and the first limiting block. The bottom of the first chute has multiple first fixing holes, and the adjusting block has a second fixing hole inside.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution uses a sliding block to move the guide plate up and down, facilitating control of the guide plate's position. The distance between the two guide plates is adjusted according to the rotor's height, ensuring the distance matches the rotor's height. This adjustment is adaptable to different rotor dimensions, broadening its applicability. Moving the rotor to the guide plate positions the rotor's slotted area between the two guide plates allows the copper wire to contact the arc surface of the guide plate as the protection mechanism rotates with the copper wire. The arc surface guides the copper wire, allowing it to slide to the rotor's position, making rotor winding more convenient.

[0020] 2. In this design, when the extrusion block moves within the extrusion groove, the top of the extrusion block presses against the inclined surface of the extrusion groove, causing the slider to move under pressure, thus facilitating the movement of the slider. During the movement of the extrusion rod, the extrusion rod and the third limiting block press against the fourth spring, causing the fourth spring to change from its naturally extended state to a taut state. After the extrusion block passes the slider, the slider, no longer obstructed by the extrusion block, moves under the action of the second spring, carrying the guide plate against the top and bottom of the rotor. After the rotor leaves, the extrusion rod returns to its original position under the action of the fourth spring. The side of the extrusion block away from the mounting block is an arc surface. The extrusion rod, carrying the extrusion block, presses against the slider, causing the slider to move again after being compressed, facilitating the return of the extrusion block and extrusion rod to their original positions.

[0021] 3. This design utilizes the arc surface of the arc plate to press against the rotor, facilitating the movement of the arc plate. The arc plate contacts the bottom of the rotor slot, and its movement causes the guide plate to move as well. This ensures that the right end of the guide plate is aligned with the bottom of the rotor slot, allowing the copper wire to slide off the guide plate surface and land at the bottom of the rotor slot. This design is suitable for rotors with varying slot depths and effectively prevents uneven winding. The arc plate is narrower than the guide plate, facilitating its entry into the rotor. The guide plate, constrained by the rotor, contacts it, making winding easier. By rotating the cylinder, the cylinder, mounting block, and guide plate rotate, adjusting the rotation angle of the slider. Bolts are then used to re-fix the frame to the cylinder. At this point, the two guide plates are inclined, facilitating winding at an angle in the rotor slots, thus broadening the applicability of the device.

[0022] 4. This solution uses a rotating rod to adjust the angle between the copper wire and the rotor, changing the shear force between them and reducing the tensile force on the copper wire. When the copper wire gets stuck in the device, the connecting rod continues to rotate, increasing the tensile force on the copper wire and its pull on the second limiting block. This causes the elastic bead to deform under excessive tension and detach from the connecting rod. As the rotating mechanism rotates the connecting rod, the rotating rod itself does not rotate, effectively preventing the device from breaking and damaging the device if the copper wire gets stuck.

[0023] 5. This solution works by pulling the copper wire when it gets stuck, making it difficult for the rotating rod to rotate with the wire. The wire then presses against the first limiting block, causing it to move within the receiving hole. This creates a gap between the first and second limiting blocks, allowing the copper wire to exit through the gap. At this point, the connecting rod rotates with the rotating rod without pulling the copper wire, effectively preventing the wire from getting stuck and breaking. This provides better protection for the device. The position of the adjusting block can be adjusted according to the thickness of the copper wire. The adjusting block is fixed by passing a bolt through the second fixing hole and then through the first fixing hole, changing the state of the first spring between the adjusting block and the first limiting block. This causes the first limiting block to be subjected to varying degrees of pressure, triggering its movement. This design has a wider range of applications. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 8A winding device for stator and rotor production includes a frame 1. A hydraulic cylinder 2 is fixedly connected to the top of one side of the frame 1, fixing the rotor to the output shaft end of the hydraulic cylinder 2. By controlling the hydraulic cylinder 2, the output end of the hydraulic cylinder 2 moves the rotor. A rotating mechanism 11 (which is prior art and will not be described here) is fixedly connected to the other side of the frame 1. A protective mechanism 3 is provided at the top of the rotating mechanism 11. Copper wire is passed through the protective mechanism 3. When the rotating mechanism 11 drives the protective mechanism 3 to rotate, the protective mechanism 3 rotates with the copper wire, facilitating the winding of the copper wire inside the rotor. A wire guiding mechanism 4 is provided on one side of the frame 1. The machine includes a cylinder 42 movably connected to the frame 1. A mounting block 41 is fixedly connected to the right side of the cylinder 42. A slider 43 is slidably connected inside the mounting block 41. The slider 43 is moved, and a guide plate 431 is slidably connected to the top of the slider 43. By moving the slider 43, the slider 43 moves up and down with the guide plate 431, which facilitates the control of the position of the guide plate 431. The distance between the two guide plates 431 can be adjusted according to the height of the rotor so that the distance between the two guide plates 431 is the same as the height of the rotor. This can be adjusted according to the size of the rotor, making it more widely applicable. The rotor is moved to the guide plate 431 so that the slotted position of the rotor is in the position of the two guide plates. Between the guide plates 431, when the protection mechanism 3 rotates with the copper wire, the copper wire contacts the arc surface of the guide plate 431. The arc surface of the guide plate 431 guides the copper wire, allowing it to slide to the rotor position, making it easier to wind the rotor. The slider 43 extends towards the mounting block 41 near the mounting block 41 to form a first extension block 433. During the movement of the slider 43, the slider 43 moves with the first extension block 433. The mounting block 41 has a second groove 411 inside corresponding to the position of the first extension block 433 to accommodate the movement of the first extension block 433. The first extension block 433 moves within the second groove 411, allowing the first extension block 433 to move. The movement of the extension block 433 is more convenient, and the movement direction of the first extension block 433 is restricted to prevent the shaking of the first extension block 433 from causing the guide plate 431 to shake, which would lead to the deflection of the winding. The second slide groove 411 is provided with a second spring 412 welded to the first extension block 433. When the slider 43 moves and moves the first extension block 433, the movement of the first extension block 433 compresses the second spring 412. After being compressed, the second spring 412 changes from its original naturally extended state to a taut state, which makes it easier for the slider 43 to return to its original position under the action of the second spring 412. This allows the movement of the guide plate 431 to be repeated, making it more widely applicable.

[0036] like Figures 1 to 8As shown, a pressing rod 44 is slidably connected inside the mounting block 41. When the hydraulic cylinder 2 moves the rotor towards the moving guide mechanism 4, the rotor presses the pressing rod 44, causing the pressing rod 44 to move into the mounting block 41. Pressing blocks 441 are fixedly connected to both the top and bottom of the pressing rod 44, facilitating the movement of the pressing rod 44 and its accompanying pressing blocks 441 into the mounting block 41. An pressing groove 434 is provided inside the slider 43. During the movement of the pressing rod 44, the pressing block 441 moves within the pressing groove 434. The pressing groove 434 has a right-angled trapezoidal cross-section, and its inclined surface is at the top of the pressing block 441. When the pressing block 441 moves within the pressing groove 434, its top presses against the inclined surface of the pressing groove 434, causing the slider 43 to move under pressure, thus facilitating its movement. The mounting block 41 is internally fixedly connected to a third limiting block 413. The pressing rod 44 is internally provided with a fourth spring 45 welded to the third limiting block 413. During the movement of the pressing rod 44, the pressing rod 44 and the third limiting block 413 press the fourth spring 45, causing the fourth spring 45 to change from its original naturally extended state to a taut state. When the pressing block 441 passes the slider 43, the slider 43, without the obstruction of the pressing block 441, presses against the top and bottom of the rotor under the action of the second spring 412, along with the guide plate 431. When the rotor leaves, the pressing rod 44 returns to its original position under the action of the fourth spring 45. The side of the pressing block 441 away from the mounting block 41 is an arc surface. The pressing rod 44, along with the pressing block 441, presses the slider 43, causing the slider 43 to move again after being pressed, making it convenient for the pressing block 441 and the pressing rod 44 to return to their original positions.

[0037] like Figures 1 to 8As shown, an arc-shaped plate 432 is fixedly connected to the bottom right side of the guide plate 431. When the guide plate 431 moves downward, it moves along with the arc-shaped plate 432. The bottom of the guide plate 431 contacts the end of the rotor, while the arc-shaped plate 432 enters the slot opened in the rotor. The contact surface between the arc-shaped plate 432 and the rotor is an arc surface. The arc surface of the arc-shaped plate 432 presses against the rotor, facilitating the movement of the arc-shaped plate 432. The arc-shaped plate 432 contacts the bottom of the rotor slot, and the movement of the arc-shaped plate 432 causes the guide plate 431 to move, ensuring that the right end of the guide plate 431 is on the same vertical plane as the bottom of the rotor slot. This design allows the copper wire to slide off the guide plate 431 and land at the bottom of the rotor slot, making it suitable for rotors of different slot depths and effectively preventing uneven winding. The arc plate 432 is narrower than the guide plate 431, facilitating its entry into the rotor. The guide plate 431, constrained by the rotor, contacts it, making winding easier. The guide plate 431 extends from the side of the slider 43 towards the slider 43 to form a second extension block 435. During the movement of the guide plate 431, it carries the second extension block 435. The slider 43 has internal features that interact with the second extension block 435. The welded third spring 436 is compressed by the movement of the second extension block 435, facilitating the return of the guide plate 431 to its original position under the action of the third spring 436. This makes the device more convenient to use. The arc-shaped part of the guide plate 431 is rotatably connected to the cuboid part. By rotating the arc-shaped part of the guide plate 431, the arc-shaped plate 432 can be rotated. When encountering a rotor with a small slot width, only the arc-shaped part of the guide plate 431 needs to be rotated, and the arc-shaped surface of the arc-shaped plate 432 guides the copper wire, effectively preventing the wire from winding into other slots. This broadens the applicability. The outer surface of the left side of the cylinder 42 extends into a shape... The outer ring 421 has multiple mounting holes 422 arranged in a ring array inside. When the rotor slot is oblique, the bolts in the mounting holes 422 are removed, changing the relationship between the cylinder 42 and the frame 1 from a fixed state to a rotatable state. By rotating the cylinder 42, the cylinder 42 rotates along with the mounting block 41 and the guide plate 431, adjusting the rotation angle of the slider 43. Then, the bolts are used to fix the frame 1 and the cylinder 42 again. At this time, the two guide plates 431 are in an inclined state, which facilitates winding the rotor slot when it is oblique, making the device more widely applicable.

[0038] like Figures 1 to 8As shown, the protection mechanism 3 includes a connecting rod 31 fixed to the rotating mechanism 11. A rotating rod 32 is rotatably connected to the right side of the connecting rod 31. An elastic bead 324 is fixedly connected to one end of the rotating rod 32 near the connecting rod 31. The elastic bead 324 extends into the interior of the connecting rod 31, allowing the rotating rod 32 to rotate on one side of the connecting rod 31. A receiving hole 323 is provided on the side of the rotating rod 32 away from the connecting rod 31. A copper wire passes through the receiving hole 323. The rotation of the connecting rod 31 causes the rotating rod 32 to rotate, which in turn causes the copper wire passing through the receiving hole 323 to rotate. This makes the rotor winding more convenient, and during the winding process, the rotating rod 32 can... The rotation adjusts the angle between the copper wire and the rotor, changing the shear force between them and reducing the tensile force on the copper wire. When the copper wire gets stuck in the device, the connecting rod 31 continues to rotate, increasing the tensile force on the copper wire and the tension on the second limiting block 34. The elastic bead 324, a solid iron ball wrapped in rubber, deforms under excessive tension and detaches from the connecting rod 31. This prevents the rotating rod 32 from rotating when the rotating mechanism 11 rotates with the connecting rod 31, thus preventing the device from breaking and damaging itself if the copper wire gets stuck.

[0039] like Figures 1 to 8As shown, a second limiting block 34 is fixedly connected to the rear side of the receiving hole 323, and a first limiting block 33 is slidably connected to the left side of the second limiting block 34. Since the opposing surfaces of the second limiting block 34 and the first limiting block 33 are inclined, the copper wire is kept between the opposing surfaces of the second limiting block 34 and the first limiting block 33. A first sliding groove 322 is provided inside the rotating rod 32 to accommodate the movement of the first limiting block 33. An adjusting block 36 is fixedly connected inside the first sliding groove 322. When the copper wire is stuck and the device continues to operate, the copper wire is pulled, making it difficult for the rotating rod 32 to rotate with the copper wire. The copper wire squeezes the first limiting block 33, causing the first limiting block 33 to move inside the receiving hole 323, making it easy for a gap to appear between the first limiting block 33 and the second limiting block 34, allowing the copper wire to leave through the gap. At this time, the connecting rod 31 rotates with the rotating rod 32 without rotating with the copper wire. The rotation effectively prevents the copper wire from getting stuck and breaking, providing better protection for the device. A first spring 35 is welded between the adjusting block 36 and the first limiting block 33. When the first limiting block 33 moves, it compresses the first spring 35, causing it to deform and allowing the first limiting block 33 to return to its original position, making the device reusable. The bottom of the first sliding groove 322 has multiple first fixing holes 321, and the inside of the adjusting block 36 has a second fixing hole 361. The position of the adjusting block 36 can be adjusted according to the thickness of the copper wire. The adjusting block 36 is fixed by passing a bolt through the second fixing hole 361 and then through the first fixing hole 321, which changes the state of the first spring 35 between the adjusting block 36 and the first limiting block 33, causing the first limiting block 33 to be subjected to different degrees of compressive force and triggering its movement. This makes the device more widely applicable.

[0040] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
