Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically an automated rotor high-efficiency winding machine. Background Technology

[0002] The rotor of an electric motor requires copper wire to be wound around the rotor core to form the rotor winding. This necessitates a specialized winding machine to achieve high-precision, high-speed winding of the motor rotor coils, widely used in household appliances (such as air conditioner compressors and washing machine motors), industrial motors, and new energy vehicle drive motors. However, a drawback is that while winding the rotor using a winding machine achieves higher production efficiency, the rotor clamping structure is not conducive to self-centering, and the clamping operation is cumbersome, resulting in low production efficiency. To address these shortcomings, existing technology (application number: 202120910026)... Chinese Patent No. 5, authorized on December 21, 2021, discloses a high-efficiency generator winding machine. It features a clamping assembly, a first pneumatic rod, a lifting plate, a pressure spring, and a pressure block for convenient clamping. Operation is simple and convenient. The clamping assembly, in conjunction with the conical groove of the pressure block, automatically centers and clamps the rotor, providing an automatic centering function. The pressure spring's elasticity prevents loosening, ensuring high clamping reliability. The machine also facilitates movement by incorporating a support column, a third pneumatic rod, a fixing plate, and casters. The retractable casters allow for easy movement by extending them and enhance stability by retracting them.

[0003] Existing technology uses clamping components to clamp and fix the rotor, and winding components to wind the rotor. However, existing rotor winding machines mostly use a single winding head, which requires winding slot by slot and cannot operate in parallel, resulting in low production efficiency. At the same time, it is difficult to support complex winding processes (such as fractional slot winding, multi-layer winding), and it is only suitable for simple centralized winding or distributed winding, resulting in limited winding types. Furthermore, the lack of limiting and fixing of the rotor core makes the rotor core prone to displacement during winding, affecting winding accuracy. Therefore, we propose an automated high-efficiency rotor winding machine that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automated high-efficiency rotor winding machine to solve the problems mentioned in the background art. Existing rotor winding machines mostly use a single winding head, which requires winding slot by slot and cannot operate in parallel, resulting in low production efficiency. At the same time, they are difficult to support complex winding processes (such as fractional slot winding, multi-layer winding), and are only suitable for simple centralized winding or distributed winding, resulting in a single winding type. Furthermore, the lack of limiting and fixing the rotor core makes the rotor core prone to displacement during the winding process, affecting the winding accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated rotor high-efficiency winding machine, comprising a frame, with movable seats provided on both the left and right sides of the upper surface of the frame, and a first motor mounted on the opposite face of each of the two movable seats, the output end of the first motor being rotatably connected to a winding head via a rotating shaft; further comprising: guide wheels rotatably connected at equal intervals at the top and bottom of the two winding heads via shafts, and limit blocks fixedly connected to the opposite face of each of the two winding heads; a support plate fixed on the upper surface of the frame, and a second motor mounted on the lower back of the support plate; a rotating cylinder and a small gear respectively provided on the front side of the support plate; clamping plates connected at equal angles to the front end of the rotating cylinder, and connecting rods fixedly connected to the opposite sides of the four clamping plates; a return spring installed between the outer side of the connecting rod and the inner wall of the rotating cylinder; and a large gear fixedly sleeved on the outer side of the rotating cylinder.

[0006] Preferably, both movable seats are slidably mounted on the upper surface of the frame via sliders, and the rotating shaft passes through the interior of the movable seats.

[0007] Preferably, the pinion is rotatably connected to the front of the support plate via a shaft, and the shaft end of the pinion passes through the interior of the support plate. The shaft end of the pinion is fixedly connected to the output end of the second motor, and the pinion and the large gear are meshed.

[0008] Preferably, the rotating cylinder bearing is connected to the front of the support plate, the end of the connecting rod away from the clamping plate extends out of the outer surface of the rotating cylinder, and the clamping plate is slidably connected to the inside of the rotating cylinder through the connecting rod.

[0009] Preferably, the support plate is rotatably connected to a transmission rod located below the pinion on its front side, and a sleeve is fitted on the outer side of the lower end of the transmission rod. A ratchet assembly is installed between the sleeve and the transmission rod. A turntable is fixedly fitted on the outer side of the sleeve, and the turntable is connected to both movable seats via movable plates.

[0010] Preferably, the top of the transmission rod is connected to the front end of the pinion shaft via a bevel gear set, and the sleeve forms a unidirectional rotating structure through a ratchet assembly, transmission rod, bevel gear set, and pinion.

[0011] Preferably, the two ends of the movable plate are hinged to the bottom of the turntable and the back of the movable seat, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This automated high-efficiency rotor winding machine, with its dual winding heads, can simultaneously wind two slots or different windings of the rotor core, thereby improving production efficiency and supporting complex winding processes. Furthermore, by utilizing the clamping plate, connecting rod, and return spring, the shaft end of the rotor core can be clamped and fixed, and the rotor core is limited and fixed by two limiting blocks moving relative to it, thus preventing the rotor core from shifting during winding and ensuring winding accuracy. The specific details are as follows:

[0013] (1) The second motor drives the small gear to rotate in the opposite direction, which in turn drives the meshing large gear to rotate. The bevel gear set drives the transmission rod to rotate, and the transmission rod drives the sleeve to rotate through the ratchet assembly. This causes the sleeve to rotate the turntable, and the two connecting plates pull the two movable seats to move relative to each other. At the same time, the two limit blocks limit and fix the rotor core, thereby preventing the rotor core from deviating during the winding process and ensuring winding accuracy. Furthermore, when the second motor drives the small gear to rotate in the forward direction, the sleeve will not rotate, causing the small gear to drive the meshing large gear to rotate. This causes the rotating cylinder to rotate the rotor core intermittently, thereby ensuring that the coils are neatly arranged and helping to maintain stable tension during the winding process, reducing damage to the enameled wire.

[0014] (2) When the shaft end of the rotor core is inserted into the rotating cylinder, it will squeeze the four clamping plates and cause them to move outward. Then, as the shaft end of the rotor core extends in, the four clamping plates clamp and fix the shaft end of the rotor core under the action of the connecting rod and the return spring, thereby ensuring the coaxiality and stability of the rotor core during the winding process.

[0015] (3) The two first motors drive the two winding heads to rotate at high speed around the rotor core through the rotating rod, thereby winding the rotor core, which can improve the working efficiency and make the rotor winding more efficient. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-7 The present invention provides the following technical solution: an automated rotor high-efficiency winding machine;

[0026] Example 1: To address the problem that existing rotor winding machines mostly use a single winding head 4, which requires winding slot by slot and cannot operate in parallel, resulting in low production efficiency, and are unable to support complex winding processes (such as fractional slot windings and multi-layer windings), they are only suitable for simple centralized or distributed windings, leading to a limited range of winding types. Furthermore, the lack of a mechanism to limit and fix the rotor core makes it prone to displacement during winding, affecting winding accuracy. Therefore, the following solution is disclosed. Please refer to the following for details. Figures 1-4 and Figure 6 and Figure 7As shown, the device includes a frame 1, with movable seats 3 on both the left and right sides of the upper surface of the frame 1. A first motor is installed on the opposite side of each of the two movable seats 3, and the output end of the first motor is rotatably connected to a winding head 4 via a rotating shaft 5. The two movable seats 3 are slidably mounted on the upper surface of the frame 1 via sliders, and the rotating shaft 5 passes through the interior of the movable seats 3. The device also includes: guide wheels 6 are rotatably connected at equal intervals above and below the interior of the two winding heads 4 via shafts, and limit blocks 7 are fixedly connected to the opposite sides of the two winding heads 4. A support plate 2 is fixed on the upper surface of the frame 1, and a second motor is installed on the lower back of the support plate 2. A rotating cylinder 10 and a small gear 12 are respectively provided on the front of the support plate 2. A large gear 11 is fixedly fitted on the outer side of the rotating cylinder 10. The small gear 12 is rotatably connected to the front of the support plate 2 via a shaft, and the shaft end of the small gear 12 passes through the interior of the support plate 2. The shaft end of the small gear 12 is fixedly connected to the output end of the second motor, and the small gear 12 and the large gear 11 are meshed.

[0027] In use, the shaft end of the rotor core is inserted into the rotating cylinder 10 and fixed by four clamping plates 16. Then, the second motor drives the pinion 12 to rotate in the opposite direction, causing the pinion 12 to drive the meshing large gear 11 to rotate. The bevel gear set drives the transmission rod 13 to rotate, and the transmission rod 13 drives the sleeve 9 to rotate via the ratchet assembly 14. This causes the sleeve 9 to drive the turntable 15 to rotate, and the two movable plates 8 pull the two movable seats 3 to move relative to each other. At the same time, the two limit blocks 7 limit and fix the rotor core, thereby preventing the rotor core from being... During the winding process, a deviation occurs to ensure winding accuracy. Then, the two first motors drive the two winding heads 4 to rotate at high speed around the rotor core via the rotating shaft 5, winding the rotor core, thereby improving work efficiency and making rotor winding more efficient. Afterwards, when the second motor drives the pinion 12 to rotate in the forward direction, the sleeve 9 does not rotate, causing the pinion 12 to drive the meshing large gear 11 to rotate, which in turn causes the rotating cylinder 10 to drive the rotor core to rotate intermittently, thereby ensuring that the coils are neatly arranged and helping to maintain stable tension during the winding process, reducing damage to the enameled wire.

[0028] Example 2: Unlike Example 1, this example uses a clamping plate 16 to clamp and fix the shaft end of the rotor core, ensuring the coaxiality and stability of the rotor core during winding. See details in the following example. Figure 5 As shown, clamping plates 16 are connected at equal angles to the front end of the inside of the rotating cylinder 10, and connecting rods 17 are fixedly connected to the opposite sides of the four clamping plates 16. A return spring is installed between the outer side of the connecting rod 17 and the inner wall of the rotating cylinder 10. The rotating cylinder 10 is connected to the front side of the support plate 2 by a bearing. The end of the connecting rod 17 away from the clamping plates 16 extends out of the outer surface of the rotating cylinder 10. The clamping plates 16 are slidably connected to the inside of the rotating cylinder 10 through the connecting rods 17.

[0029] When the shaft end of the rotor core is inserted into the rotating cylinder 10, it will squeeze the four clamping plates 16, causing them to move outward. Then, as the shaft end of the rotor core extends in, the four clamping plates 16, under the action of the connecting rod 17 and the return spring, clamp and fix the shaft end of the rotor core, thereby ensuring the coaxiality and stability of the rotor core during the winding process.

[0030] Example 3: Unlike Example 2, in this example, as the turntable 15 continues to rotate, the movable plate 8 drives the two movable seats 3 to move in opposite directions, thereby facilitating the removal of the wound rotor core. See details... Figure 4 , Figure 6 and Figure 7 As shown, the support plate 2 is rotatably connected to the transmission rod 13 below the pinion 12. A sleeve 9 is fitted on the outer side of the lower end of the transmission rod 13. A ratchet assembly 14 is installed between the sleeve 9 and the transmission rod 13. The top of the transmission rod 13 is connected to the front end of the shaft of the pinion 12 through a bevel gear set. The sleeve 9 forms a unidirectional rotation structure through the ratchet assembly 14, the transmission rod 13, the bevel gear set, and the pinion 12. A turntable 15 is fixedly fitted on the outer side of the sleeve 9. The turntable 15 is connected to both movable seats 3 through movable plates 8. The two ends of the movable plates 8 are hinged to the bottom of the turntable 15 and the back of the movable seat 3, respectively.

[0031] After the rotor core is wound, as the second motor drives the small gear 12 to continue rotating in the opposite direction, the small gear 12 drives the meshing large gear 11 to continue rotating, and uses the bevel gear set to drive the transmission rod 13 to rotate. At the same time, the transmission rod 13 uses the ratchet assembly 14 to drive the sleeve 9 to rotate, which in turn causes the sleeve 9 to drive the turntable 15 to rotate, and uses the two connecting plates to push the two movable seats 3 to move in opposite directions, so that the two limit blocks 7 move in opposite directions and no longer limit and fix the rotor core, thus making it easier for the staff to take out the wound rotor core.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
