Description

Technical Field

[0001] This application relates to the field of stator winding shaping technology, specifically a stator winding shaping device for new energy vehicle motors. Background Technology

[0002] Stator shaping is a key process in motor manufacturing where the ends of the stator windings are precisely trimmed. It aims to ensure the precise spatial position of the coil ends, improve insulation reliability, reduce friction to enhance motor durability, and create favorable conditions for subsequent assembly.

[0003] However, in actual operation, power lines are usually connected to the stator windings. When the forming wheel squeezes the windings, the power lines and their lugs are easily squeezed, which can lead to damage to the power lines and deformation of the lugs, affecting the electrical connection performance of the motor and even causing safety hazards.

[0004] To address this issue, during stator shaping, workers typically need to manually hold the power cord to keep it vertically upward, thus preventing the power cord and lugs from being squeezed by the shaping rollers. However, new problems arise during the stator shaping rotation process. This not only greatly increases the labor intensity for workers, making the shaping work cumbersome and inefficient, but also makes workers prone to operational errors due to fatigue during prolonged operation, further increasing safety hazards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a stator winding shaping device for new energy vehicle motors, which has advantages such as preventing power line compression and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a stator winding shaping device for a new energy vehicle motor, comprising a worktable, two shaping shafts rotatably connected above the worktable, two shaping wheels fixedly connected to the outer surface of each shaping shaft, a fixing component provided above the worktable, the fixing component including a support frame, a fixing column rotatably connected to the top of the support frame, two socket plates fixedly connected to the outer surface of the fixing column, and a driving mechanism for driving the fixing component to move linearly above the worktable;

[0007] The top of the fixing column has a slot along its axial direction. The inner wall of the slot is provided with two symmetrical wire harness fixing components. The two wire harness fixing components are arranged horizontally along the radial direction of the fixing column. The wire harness fixing components include a fixing block. The fixing block is fixedly connected to the two inner side walls of the slot. Two elastic plates are fixedly installed on the side of the fixing block away from the fixing column. The two elastic plates are arranged in an arc shape and are symmetrical.

[0008] Furthermore, the driving mechanism includes two guide rods, each end of which is fixedly connected to a mounting block. Each mounting block is fixedly connected to the upper surface of the worktable, and the support frame is slidably connected to the two guide rods.

[0009] The driving mechanism also includes a cylinder, which is fixedly connected to the worktable, and the output end of the cylinder is fixedly connected to the support frame.

[0010] Through the above scheme, the cylinder can stably drive the support frame to move linearly along the guide rod, thereby driving the fixed column to move closer to or away from the shaping axis, realizing the precise shaping operation of the stator winding. Moreover, the setting of the guide rod ensures the smoothness and straightness of the support frame movement, improving the shaping accuracy.

[0011] Furthermore, two cleaning shafts are rotatably connected to the upper surface of the workbench, and cleaning cotton is fixedly connected to the outer surface of each of the two cleaning shafts. The two cleaning cottons are in contact with their corresponding shaping wheels.

[0012] With the above solution, the cleaning cotton can clean the surface of the shaping wheel in real time during the rotation of the shaping wheel, removing impurities, winding debris and other contaminants that may be attached to the surface of the shaping wheel, ensuring the cleanliness of the surface of the shaping wheel, thereby ensuring that the squeezing effect of the shaping wheel on the winding is uniform and consistent, and improving the shaping quality.

[0013] Furthermore, two scrapers are fixedly connected to the upper surface of the workbench, with each scraper distributed along the height of the workbench and in contact with its corresponding cleaning cotton.

[0014] Through the above solution, as the cleaning cotton rotates with the cleaning shaft, the scraper can remove larger particles and excess stains adsorbed on the cleaning cotton, preventing these impurities from re-adhering to the shaping wheel, further ensuring the effective cleaning of the shaping wheel by the cleaning cotton, extending the service life of the cleaning cotton, and maintaining the good operating condition of the shaping device.

[0015] Furthermore, a first gear is fixedly connected to the bottom end of each of the two shaping shafts, a power shaft is rotatably connected to the bottom of the worktable, a second gear is fixedly connected to the outer surface of the power shaft, the two first gears and the two second gears mesh with each other, and the bottom end of the power shaft is fixedly connected to the external motor output end.

[0016] With the above scheme, an external motor drives the power shaft to rotate, and the second gear on the power shaft drives the two first gears to rotate, thereby making the two cleaning shafts rotate synchronously, so as to achieve continuous cleaning of the shaping wheel by the cleaning cotton. This ensures that the cleaning shafts rotate according to the set speed and direction, meeting the cleaning requirements of the shaping device.

[0017] Furthermore, each of the shaping wheels has an anti-slip textured layer on its outer surface.

[0018] By implementing the above solution and setting an anti-slip textured layer, the friction between the forming wheel and the winding can be increased during the contact and rotation of the forming wheel with the stator winding, preventing slippage during the forming process. This ensures that the forming wheel can apply pressure to the winding stably and effectively, achieving more precise and efficient winding forming operations.

[0019] Furthermore, a set of casters is installed at the bottom of the workbench.

[0020] The above solution, by installing casters, allows staff to flexibly move the entire stator winding shaping device of the new energy vehicle motor according to actual usage scenarios and needs.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This new energy vehicle motor stator winding shaping device effectively fixes the power wire harness during stator winding shaping by setting a fixing component and a wire harness fixing component. During shaping, the stator is fitted into the fixing post, and two sleeve plates are used to make close contact with the inner wall of the stator. Then, the fixing component is driven by the drive mechanism to move closer to the shaping shaft, so that the stator winding contacts the shaping wheel for shaping. The power wire harness is fixed between two symmetrical, arc-shaped, X-shaped elastic plates in the slot of the fixing post. The wire harness squeezes the contact points of the elastic plates to make them move away from each other and enter the interior. The elastic plates reset and firmly fix the wire harness. This avoids the shaping wheel squeezing the power wire and wire lug during the winding shaping process, ensuring the smooth progress of the shaping process. It solves the problems of high labor intensity, cumbersome and inefficient operation, and easy operation errors and safety hazards caused by workers manually holding the power wire in the traditional method.

[0023] By incorporating a cleaning shaft, cleaning cotton, and scraper, the cleaning cotton continuously cleans the surface of the shaping wheel during its rotation, removing any impurities and winding debris that may adhere to it. This ensures the cleanliness of the shaping wheel surface, guarantees a uniform and consistent compression effect on the winding, and improves the shaping quality. The scraper removes larger particles and excess dirt adsorbed on the cleaning cotton as it rotates with the cleaning shaft, preventing impurities from re-adhering to the shaping wheel. This further ensures effective cleaning of the shaping wheel by the cleaning cotton, extends its service life, and maintains the good operating condition of the shaping device.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Please see Figures 1-6This embodiment of a new energy vehicle motor stator winding shaping device includes a worktable 1. Two shaping shafts 2 are rotatably connected above the worktable 1. Two shaping wheels 3 are fixedly connected to the outer surface of each shaping shaft 2. A fixing assembly 4 is provided above the worktable 1. The fixing assembly 4 includes a support frame 401. A fixing column 402 is rotatably connected to the top of the support frame 401. Two socket plates 403 are fixedly connected to the outer surface of the fixing column 402. A driving mechanism 5 is provided above the worktable 1 to drive the fixing assembly 4 to move linearly. Through the driving mechanism 5, the fixing column 402 can be driven to move closer to the shaping shaft 2. In use, the stator is fitted into the fixing column 402, and the outer surfaces of the two socket plates 403 are in close contact with the inner wall of the stator. After installation, the driving mechanism 5 drives the fixing assembly 4 to move closer to the shaping shaft 2, so that the top and bottom windings of the stator are distributed on the two shaping wheels of the two shaping shafts 2. The winding is shaped by the rotation and compression of the shaping wheel 3. Simultaneously, friction drives the stator and fixed column 402 to rotate, achieving uniform pressure and efficient shaping of the winding. The drive mechanism 5 includes two guide rods 501, each with a mounting block 502 fixedly connected to both ends. Each mounting block 502 is fixedly connected to the upper surface of the worktable 1. The support frame 401 is slidably connected to the two guide rods 501. The drive mechanism 5 also includes a cylinder 503, which is fixedly connected to the worktable 1. The output end of the cylinder 503 is fixedly connected to the support frame 401. The cylinder 503 can stably drive the support frame 401 to move linearly along the guide rods 501, thereby causing the fixed column 402 to move closer to or further away from the shaping shaft 2, achieving precise shaping of the stator winding. The guide rods 501 ensure the smoothness and straightness of the support frame 401's movement, improving shaping accuracy.

[0039] The top of the fixing post 402 has a slot 6 along its axial direction. Two symmetrical wire harness fixing assemblies 7 are arranged on the inner wall of the slot 6. The two wire harness fixing assemblies 7 are arranged horizontally along the radial direction of the fixing post 402. Each wire harness fixing assembly 7 includes a fixing block 701, which is fixedly connected to the two inner side walls of the slot 6. Two elastic plates 702 are fixedly installed on the side of the fixing block 701 away from the fixing post 402. The two elastic plates 702 are integrally formed from spring steel, possessing good elasticity and resistance to deformation. The two elastic plates 702 are arranged in an arc shape, and the two... The elastic plates 702 are symmetrically arranged, with the two elastic plates 702 forming an X shape. During the shaping process, by fixing the power cable harness between the two sets of elastic plates 702, the shaping wheel 3 can be prevented from squeezing the power cable and the wire lug during the winding shaping process. When fixing the cable harness, due to the X-shaped arrangement of the elastic plates 702, the cable harness can squeeze the contact points of the two elastic plates 702, causing the two elastic plates 702 to move away from each other and then enter the interior of the two elastic plates 702. After entering, the elastic plates 702 return to their original position, thereby firmly fixing the cable harness and ensuring the smooth progress of the shaping process.

[0040] Two cleaning shafts 8 are rotatably connected to the upper surface of the workbench 1. Cleaning cotton 9 is fixedly connected to the outer surface of each of the two cleaning shafts 8. The two cleaning cotton 9s are in contact with their corresponding shaping wheels 3. During the rotation of the shaping wheels 3, the cleaning cotton 9 can clean the surface of the shaping wheels 3 in real time, removing impurities, winding debris, etc. that may be attached to the surface of the shaping wheels 3, ensuring the cleanliness of the surface of the shaping wheels 3, thereby ensuring that the extrusion effect of the shaping wheels 3 on the windings is uniform and consistent, and improving the shaping quality. Two scrapers 10 are fixedly connected to the upper surface of the workbench 1. The two scrapers 10 are distributed along the height of the workbench 1, and each scraper 10 is in contact with its corresponding cleaning cotton 9. During the rotation of the cleaning cotton 9 with the cleaning shafts 8, the scrapers 10 can scrape off larger particles of impurities and excess stains adsorbed on the cleaning cotton 9, preventing these impurities from re-adhering to the shaping wheels 3, and further ensuring the effective cleaning of the shaping wheels 3 by the cleaning cotton 9.

[0041] Two shaping shafts 2 are each fixedly connected to a first gear 11 at their bottom ends. A power shaft 14 is rotatably connected to the bottom of the worktable 1. A second gear 12 is fixedly connected to the outer surface of the power shaft 14. The two first gears 11 and the two second gears 12 mesh with each other. The bottom end of the power shaft 14 is fixedly connected to the output end of an external motor. The external motor drives the power shaft 14 to rotate, and the second gear 12 on the power shaft 14 drives the two first gears 11 to rotate, thereby causing the two cleaning shafts 8 to rotate synchronously. This enables the cleaning cotton 9 to continuously clean the shaping wheel 3, ensuring that the cleaning shaft 8 rotates according to the set speed and direction, thus satisfying the cleaning requirements. To meet the cleaning requirements of the shaping device, each shaping wheel 3 has an anti-slip textured layer on its outer surface. By setting the anti-slip textured layer, the friction between the shaping wheel 3 and the winding can be increased during the contact and rotation of the shaping wheel 3 with the stator winding, preventing slippage during the shaping process. This ensures that the shaping wheel 3 can stably and effectively apply pressure to the winding, achieving more precise and efficient winding shaping operations. A set of universal wheels 13 is installed at the bottom of the workbench 1. By installing the universal wheels 13, it is convenient for the staff to flexibly move the entire new energy vehicle motor stator winding shaping device according to the actual usage scenario and needs.

[0042] The working principle of the above embodiment is as follows: The worker puts the new energy vehicle motor stator to be shaped onto the fixing post 402 of the fixing assembly 4. The two sockets 403 on the outer surface of the fixing post 402 will be in close contact with the inner wall of the stator. At the same time as the stator is put into the fixing post 402, the power harness connected to the stator needs to be fixed. The worker places the power harness between two elastic plates 702. The harness squeezes the contact point of the two elastic plates 702, so that the two elastic plates 702 move away from each other, and the harness can enter the interior of the two elastic plates 702. After entering, the elastic plates 702 rely on their own elasticity to reset, thereby firmly fixing the harness, avoiding the shaping wheel 3 from squeezing the power wire and wire lug during the subsequent winding shaping process, and ensuring the smooth progress of the shaping process.

[0043] After the stator installation and wiring harness fixing are completed, the drive mechanism 5 is started. After the cylinder 503 is started, the output end pushes the support frame 401 to move linearly along the guide rod 501. Since the fixed column 402 is installed at the top of the support frame 401, the fixed column 402 will move closer to the shaping shaft 2 along with the support frame 401. As the fixed column 402 moves closer to the shaping shaft 2, the top winding and bottom winding of the stator contact the two shaping wheels 3 on the two shaping shafts 2 respectively.

[0044] An external motor drives the power shaft 14 to rotate. A second gear 12 is fixedly connected to the outer surface of the power shaft 14. A first gear 11 is fixedly connected to the bottom end of each of the two shaping shafts 2. The two first gears 11 mesh with the two second gears 12. When the power shaft 14 rotates, the two first gears 11 are driven to rotate through the second gears 12, thereby causing the two shaping shafts 2 to rotate synchronously. The shaping wheel 3 on the shaping shaft 2 also rotates accordingly. During the rotation, the shaping wheel 3 squeezes the stator winding to achieve the purpose of shaping the winding. At the same time, due to the friction between the shaping wheel 3 and the winding, the stator and the fixed column 402 will rotate, so that the winding can be evenly compressed.

[0045] Two cleaning shafts 8 are rotatably connected to the upper surface of the workbench 1. Cleaning cotton 9 is fixedly connected to the outer surface of each of the two cleaning shafts 8, and each cleaning cotton 9 contacts its corresponding shaping wheel 3. During the rotation of the shaping wheel 3, the cleaning cotton 9 cleans the surface of the shaping wheel 3 in real time, removing any impurities, winding debris, etc., that may adhere to the surface of the shaping wheel 3, ensuring the cleanliness of the surface of the shaping wheel 3. Two scraper blades 10 are fixedly connected to the upper surface of the workbench 1, and are set along the height of the workbench 1. Each scraper blade 10 contacts its corresponding cleaning cotton 9. As the cleaning cotton 9 rotates with the cleaning shafts 8, the scraper blades 10 can scrape off larger particles and excess dirt adsorbed on the cleaning cotton 9, preventing these impurities from re-adhering to the shaping wheel 3, further ensuring the effective cleaning of the shaping wheel 3 by the cleaning cotton 9, extending the service life of the cleaning cotton 9, and maintaining the good operating condition of the shaping device.
