Abstract
Description
Technical Field
[0001] This utility model relates to the field of stator and rotor lamination processing technology, specifically a generator stator and rotor lamination processing device. Background Technology
[0002] An electric motor is an electrical device widely used in industrial production and daily life. An electric motor includes components such as a stator, rotor, shaft, and end cover. The stator and rotor are manufactured by stacking and pressing stamped laminations. After stamping, the stator and rotor laminations are usually separated using a separation die. Then, the outer diameter of the rotor laminations is machined to leave an appropriate air gap between the rotor and stator after installation. However, the debris generated during the machining of the outer diameter of the rotor laminations can affect the quality of the die processing.
[0003] Existing technology, such as publication number CN214392070U, provides a composite stamping die for generator rotor laminations, including a mounting platform and casters fixed to the corner of the lower surface of the mounting platform. A lower die is fixed to the upper surface of the mounting platform, and reset components are fixed to both the front and rear ends of the upper surface of the mounting platform. A mounting plate is fixed to the upper surface of the reset components, and an upper die is fixed to the lower surface of the mounting plate. A scrap bin is movably fitted onto the right surface of the mounting platform, and a material collection component is fixed to the left surface of the mounting platform. Stabilizing components are movably fitted to both the front and rear ends of the lower surface of the mounting platform. This allows for the cleaning of debris generated during stamping, preventing debris from affecting the processing quality of the die. A cylinder pushes the debris into the scrap bin via a brush, facilitating the centralized cleaning of processing debris. The distance between the support base plate and the placement plane can be adjusted by rotating an adjustment block, allowing for the transfer or fixing of the device, increasing the flexibility of the device.
[0004] The current solution uses a cylinder to drive a brush for cleaning. However, due to the soft material of the brush and the gaps between the bristles, the cleaning efficiency is generally low. Therefore, we propose a generator stator and rotor lamination processing device. Utility Model Content
[0005] The purpose of this utility model is to provide a generator stator and rotor lamination processing device, which solves the problem that the debris generated during the processing of the outer diameter of the rotor lamination will affect the quality of the mold processing.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A generator stator and rotor lamination processing device includes a worktable, a fixing mechanism is provided on the top left side of the worktable, a cleaning mechanism is provided in the middle of the worktable, and a grinding assembly is provided on the top of the worktable between the cleaning mechanism and the fixing mechanism. The grinding assembly includes a linear motor, which is fixedly connected to the top of the worktable. A support rod is slidably connected to the top of the linear motor, and a cylindrical grinding stone is fixedly connected to the lower part of the top of the support rod.
[0008] The cleaning mechanism includes an air suction hood positioned outside the cylindrical polishing stone.
[0009] Preferably, the cleaning mechanism further includes a second gear, which is rotatably connected to the top of the workbench. A rotating cylinder is fixedly connected to the second gear, and a turbine is fixedly connected to the inner wall of the rotating cylinder. The rotating cylinder is connected to the suction hood through an air pipe, and the end of the rotating cylinder connected to the air pipe is rotatably connected and is provided with a sealing ring.
[0010] Preferably, a third gear is meshed with the right side of the second gear, and a servo motor for driving the third gear to rotate is provided above the third gear. The servo motor is fixedly connected to the top of the worktable through a support frame, and a brake is provided on the servo motor.
[0011] Preferably, the cleaning mechanism further includes a drawer box, which is slidably connected to the workbench, and the interior of the workbench is in communication with the interior of the rotating drum.
[0012] Preferably, the drawer has an exhaust vent on the front and an air filter inside.
[0013] Preferably, the fixing mechanism includes a first gear, which is rotatably connected to the top of the workbench and meshes with a second gear. A bidirectional threaded rod is rotatably connected to the top of the first gear. Threaded sleeves are threadedly connected to both sides of the outer wall of the bidirectional threaded rod. An inner liner is provided on the outer wall of the bidirectional threaded rod. The outer wall of the threaded sleeve is hinged to the inner liner at the corresponding position via a hinge rod.
[0014] Preferably, the top of the bidirectional threaded rod has a circular hole for inserting a lever to rotate the bidirectional threaded rod, and the top of the first gear has a limiting groove for sliding of the inner liner plate.
[0015] By employing the above technical solution, this utility model provides a generator stator and rotor lamination processing device. It possesses at least the following beneficial effects:
[0016] 1. This utility model starts the servo motor to drive the third gear to rotate, which in turn drives the turbine inside the rotating drum to rotate through the meshing second gear. This causes the air inside the rotating drum to flow from top to bottom, creating a negative pressure at the top of the drum. This facilitates the extraction of dust generated during the grinding of the cylindrical polishing stone through the air pipe and suction hood. While cleaning the surface of the punch, it also prevents dust from scattering and polluting the surrounding environment. Compared with the brush cleaning method in the comparative solution, it has a better cleaning effect and can clean while processing, effectively preventing dust from scattering.
[0017] II. This utility model, by setting a fixing piece for the inner liner plate, requires the fixing piece to be sleeved on the outside of the inner liner plate. By inserting a lever into the round hole, the double-threaded rod is rotated, and the inner liner plate is limited by the limiting groove, so that the threaded sleeve connected to the inner liner plate will not rotate axially on the outer wall of the double-threaded rod. This allows the spacing between the threaded sleeves to be adjusted when the double-threaded rod rotates. Since the threaded sleeve is connected to the inner liner plate by a hinge rod, when the position between the two threaded sleeves changes, the angle between the hinge rods will also change, thereby adjusting the range of inner diameter that the inner liner plate can support and fix. This facilitates fixing by the inner liner plate against the fixing piece, thereby increasing the applicability of the equipment and improving its practicality. 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] A generator stator and rotor lamination processing device, such as Figure 1 - Figure 4 As shown, the system includes a workbench 1, a fixing mechanism 2 located on the top left side of the workbench 1, a cleaning mechanism 4 located in the middle of the workbench 1, and a polishing assembly 3 located on the top of the workbench 1 between the cleaning mechanism 4 and the fixing mechanism 2. The polishing assembly 3 includes a linear motor 31, which is fixedly connected to the top of the workbench 1. A support rod 32 is slidably connected to the top of the linear motor 31, and a cylindrical polishing stone 33 is fixedly connected to the lower part of the top of the support rod 32. The cleaning mechanism 4 includes a suction hood 46 located outside the cylindrical polishing stone 33. The cleaning mechanism 4 also includes a second... Gear 42 is rotatably connected to the top of workbench 1. A rotating cylinder 43 is fixedly connected to the second gear 42. A turbine 44 is fixedly connected to the inner wall of the rotating cylinder 43. The rotating cylinder 43 is connected to the suction hood 46 through an air pipe 45. The end of the rotating cylinder 43 connected to the air pipe 45 is rotatably connected and is provided with a sealing ring. A third gear 47 is meshed with the right side of the second gear 42. A servo motor 48 for driving the rotation of the third gear 47 is provided above the third gear 47. The servo motor 48 is fixedly connected to the top of workbench 1 through a support frame 49, and a brake is provided on the servo motor 48.
[0026] In this embodiment, the servo motor 48 is started to drive the third gear 47 to rotate, and the meshing second gear 42 drives the turbine 44 inside the rotating drum 43 to rotate, so that the air inside the rotating drum 43 flows from top to bottom, creating a negative pressure at the top of the rotating drum 43. This facilitates the suction of dust generated during the grinding of the cylindrical polishing stone 33 through the air pipe 45 and the suction hood 46. While cleaning the surface of the lamination, it also prevents dust from scattering and polluting the surrounding environment. The linear motor 31 drives the cylindrical polishing stone 33 on the support rod 32 to approach the lamination for grinding, and processes the outer diameter of the rotor lamination so that an appropriate air gap is left between the rotor and the stator after installation.
[0027] like Figure 1 , Figure 2 As shown, preferably, the cleaning mechanism 4 also includes a drawer 41, which is slidably connected to the workbench 1. The interior of the workbench 1 is connected to the interior of the rotating drum 43. An exhaust hole 411 is provided on the front of the drawer 41, and an air filter 412 is provided inside the drawer 41.
[0028] In this embodiment, by setting the drawer 41 to connect with the rotating drum 43, the rotating drum 43 can draw in air containing dust, inject it into the drawer 41, and then discharge it from the exhaust port 411. The air is then filtered and intercepted by the air filter element 412, so as to facilitate the collection of dust and facilitate subsequent centralized processing.
[0029] like Figure 2 , Figure 4 As shown, preferably, the fixing mechanism 2 includes a first gear 21, which is rotatably connected to the top of the workbench 1 and meshes with a second gear 42. A bidirectional threaded rod 22 is rotatably connected to the top of the first gear 21. Threaded sleeves 23 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 22. An inner liner plate 24 is provided on the outer wall of the bidirectional threaded rod 22. The outer wall of the threaded sleeve 23 is hinged to the inner liner plate 24 at the corresponding position via a hinge rod 25. A round hole 26 is provided on the top of the bidirectional threaded rod 22 for inserting a lever to rotate the bidirectional threaded rod 22. A limiting groove 17 for sliding of the inner liner plate 24 is provided on the top of the first gear 21.
[0030] In this embodiment, by setting the inner liner plate 24 to fix the punch, the punch needs to be sleeved on the outside of the inner liner plate 24 during fixing. By inserting a lever into the round hole 26, the bidirectional threaded rod 22 is rotated. The inner liner plate 24 is limited by the limiting groove 17, so that the threaded sleeve 23 connected to the inner liner plate 24 will not rotate axially on the outer wall of the bidirectional threaded rod 22. This allows the spacing between the threaded sleeves 23 to be adjusted when the bidirectional threaded rod 22 rotates. Since the threaded sleeve 23 is connected to the inner liner plate 24 through the hinge rod 25, when the position between the two threaded sleeves 23 changes, the angle between the hinge rods 25 will also change, thereby adjusting the inner diameter range that the inner liner plate 24 can support and fix. This facilitates the fixing of the punch by the inner liner plate 24 against the punch. Furthermore, since the first gear 21 at the bottom of the bidirectional threaded rod 22 is meshed with the second gear 42, when the second gear 42 rotates, the punch fixed above the first gear 21 will also rotate together, which facilitates the grinding of the punch.
[0031] In use, the generator stator and rotor lamination processing device of this utility model fixes the laminations by setting an inner liner plate 24. During fixation, the laminations need to be sleeved on the outside of the inner liner plate 24. By inserting a lever into the round hole 26, the bidirectional threaded rod 22 is rotated. The limiting groove 17 limits the inner liner plate 24, preventing the threaded sleeves 23 connected to the inner liner plate 24 from axially rotating on the outer wall of the bidirectional threaded rod 22. This allows the spacing between the threaded sleeves 23 to be adjusted when the bidirectional threaded rod 22 rotates. Since the threaded sleeves 23 are connected to the inner liner plate 24 by hinge rods 25, when the position between the two threaded sleeves 23 changes, the angle between the hinge rods 25 also changes, thereby adjusting the range of the inner diameter that the inner liner plate 24 can support and fix. This facilitates the fixing of the laminations by the inner liner plate 24 against the laminations. The servo motor 48 is started to drive the third gear 47 to rotate, which in turn drives the inside of the rotating drum 43 through the meshing second gear 42. The rotation of the turbine 44 causes the air inside the rotating drum 43 to flow from top to bottom, creating a negative pressure at the top of the rotating drum 43. This facilitates the extraction of dust generated during the grinding of the cylindrical polishing stone 33 through the air pipe 45 and the suction hood 46. The dust-laden air is then drawn into the rotating drum 43, injected into the drawer 41, and discharged from the exhaust port 411. The dust is then filtered and intercepted by the air filter element 412 for easy collection and subsequent centralized processing. The linear motor 31 drives the cylindrical polishing stone 33 on the support rod 32 to approach the lamination for grinding, machining the outer diameter of the rotor lamination to leave an appropriate air gap between the rotor and stator after installation. Since the first gear 21 at the bottom of the bidirectional threaded rod 22 is meshed with the second gear 42, when the second gear 42 rotates, the lamination fixed above the first gear 21 also rotates, facilitating the grinding assembly 3 to grind the lamination.
