Description

Technical Field

[0001] This utility model relates to the field of motor processing technology, and more specifically, to a flipping device for processing the stator of a three-phase asynchronous motor. Background Technology

[0002] An electric motor mainly consists of a stator and a rotor. The stator is the stationary part of the motor and is located outside the motor. The rotor is the rotating part of the motor and is located inside the stator. During the assembly of the motor stator, depending on the different installation requirements of each component, the motor stator needs to be flipped upside down and rotated at all angles within 360 degrees on the horizontal plane for assembly, in order to complete the next step of stator assembly.

[0003] The generator rotor turning device disclosed in application number CN202121273550.2 is also an increasingly mature technology. The limiting plate can effectively fix the generator rotor, making it convenient for workers to adjust the turning device according to different specifications of generator rotors, reducing the labor intensity of workers, improving the working efficiency of the turning device, and effectively meeting the needs of workers.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] This type of flipping device only addresses the spacing adjustment and clamping of the motor rotor, but does not perform the flipping operation, which prevents the flipping process from proceeding smoothly and reduces the efficiency of the operation. Utility Model Content

[0006] The purpose of this invention is to provide a flipping device for processing the stator of a three-phase asynchronous motor, so as to solve the problem that the flipping processing step mentioned in the background art cannot be carried out smoothly.

[0007] This utility model provides a flipping device for processing the stator of a three-phase asynchronous motor, including a flipping device, a clamping device, and a lifting device;

[0008] The flipping device includes a square plate, a micro motor is horizontally arranged in the middle of the front side of the square plate, the output end of the micro motor passes through the horizontal plate, and limit rods are horizontally arranged on both sides of the back side of the horizontal plate. The limit rods slide inside the limit groove opened in the outer sleeve of the micro motor.

[0009] The clamping device includes a gear located in the center of the front of a horizontal plate. The central shaft of the gear is connected to the output end of a micro motor. Fixed protrusions are located on both sides of the horizontal plate, and support rods are located between the fixed protrusions. A left movable base and a right movable base are slidably arranged between the two sides of the support rods. A left long plate and a right long plate are located on the front of the left and right movable bases, respectively. A left connecting plate and a right connecting plate are located at the far ends of the left and right long plates, respectively. An upper rack is mounted on the top of the left connecting plate by a pin, and a lower rack is mounted on the bottom of the right connecting plate by a pin. The gear meshes with and drives the upper and lower racks. A through slot is opened at the bottom of the left connecting plate and the top of the right connecting plate, and the upper and lower racks are inserted into the through slot. Clamping blocks are located at the opposite ends of the tops of the left and right long plates.

[0010] In this embodiment, the rotation of the micro motor output will drive the horizontal plate to rotate synchronously. The horizontal plate drives the limiting rod to rotate inside the limiting groove, thereby keeping the horizontal plate in a stable rotation. The rotation of the micro motor drives the gear, and the rotation of the gear will mesh with the upper and lower racks. When the left and right moving bases slide along the support rod and approach each other, the racks insert into the slot. When the left and right moving bases drive the long plate to approach each other, the two clamping blocks approach each other, thereby clamping the stator.

[0011] In one embodiment of this utility model, the lifting device includes a vertically arranged mounting plate. A threaded rod is provided in the middle of the interior of the mounting plate and passes through its top end to connect to the output end of the motor. Guide rods are provided on both sides of the outer side of the threaded rod. A lifting block is threadedly connected to the threaded rod and the guide rods. The front connection dimension of the lifting block is larger than the square plate of the lifting block.

[0012] In this scheme, the rotation of the threaded rod is driven by the motor, which causes the lifting block to move along the thread of the threaded rod and slide with the guide rod to move up and down. The guide rod is used to limit the rotation of the lifting block, and the lifting of the lifting block drives the square plate to move up and down synchronously.

[0013] In one embodiment of this utility model, the mounting plate is located at the top of the desktop, and the four corners of the desktop are provided with support legs. The top of the desktop is provided with a stator housing at the corresponding position of the clamping block, and the stator housing has a positioning groove inside.

[0014] In this design, the desktop provides support for the mounting plate and the stator housing, the support legs provide height and stability for the desktop, and the stator housing has positioning grooves to facilitate the stability of the stator.

[0015] In one embodiment of this utility model, a reinforcing block is provided on the back of each clamping block, and a rubber pad is provided on the opposite end of each clamping block.

[0016] In this design, the structural strength of the clamping block and the left and right long plates is increased by reinforcing blocks, and the rubber pads increase the friction between the clamping block and the stator to prevent slippage.

[0017] In one embodiment of this utility model, the threaded rod is fitted with a bearing sleeve outside the mounting plate, and the stator housing consists of three units arranged in a row.

[0018] In this solution, the friction and wear between the threaded rod and the mounting plate are reduced by using a bearing sleeve.

[0019] In one embodiment of this utility model, a switch panel is provided on one side of the top of the desktop, and a micro motor switch and a motor switch are respectively provided on the top of the switch panel. The switch panel is electrically connected to an external power supply.

[0020] In this solution, an external power supply is connected to the switch panel, and an independent switch provides independent protection for the electrical equipment.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The electric motor drives the rotation of the threaded rod, causing the lifting block outside the threaded rod to move along the thread of the threaded rod and slide down the guide rod. The guide rod is used to limit the rotation of the lifting block and keep the lifting block moving stably. The lifting of the lifting block drives the square plate to move synchronously. When the lifting block descends to the height that can clamp the stator, when the stator is flipped, the electric motor drives the threaded rod to rotate in the opposite direction, causing the lifting block to rise. When the micro motor starts to rotate, the rotation of the output end will drive the horizontal plate to move synchronously. The rotation of the horizontal plate will drive the limit rod to rotate inside the limit groove, thereby keeping the horizontal plate rotating stably. Attached Figure Description

[0032] Example

[0033] Please see Figures 1-3 This utility model provides a flipping device for processing the stator of a three-phase asynchronous motor, including a flipping device 100, a clamping device 200, and a lifting device 300;

[0034] Please refer to the details. Figure 2 The flipping device 100 includes a square plate 110. A micro motor 111 is horizontally arranged in the middle of the front side of the square plate 110. The output end of the micro motor 111 passes through a horizontal plate 112. Limiting rods 113 are horizontally arranged on both sides of the back side of the horizontal plate 112. The limiting rods 113 slide inside the limiting grooves 115 opened in the outer sleeve 114 of the micro motor 111.

[0035] In one specific embodiment, please refer to Figure 2 When the micro motor 111 is started, the rotation of the output end will drive the horizontal plate 112 to rotate synchronously. The rotation of the horizontal plate 112 will drive the limit rod 113 to rotate inside the limit groove 115, thereby keeping the horizontal plate 112 in a stable rotation.

[0036] Please see Figure 2The clamping device 200 includes a horizontal plate 112 with a gear 210 located in the center of its front side. The central shaft of the gear 210 is connected to the output end of a micro motor 111. Fixed protrusions 211 are located on both sides of the horizontal plate 112, and support rods 212 are positioned between the fixed protrusions 211. A left movable base 213 and a right movable base 214 are slidably positioned between the two sides of the support rods 212. A left long plate 215 and a right long plate 216 are respectively located on the front of the left movable base 213 and the right movable base 214. The far sides of the left long plate 215 and the right long plate 216 are... A left connecting plate 217 and a right connecting plate 218 are respectively provided at the ends. An upper rack 219 is installed at the top of the left connecting plate 217 by a pin, and a lower rack 220 is installed at the bottom of the right connecting plate 218 by a pin. The gear 210 meshes with the upper rack 219 and the lower rack 220 to drive them. A through slot 221 is provided at the bottom of the left connecting plate 217 and the top of the right connecting plate 218. The upper rack 219 and the lower rack 220 are inserted into the through slot 221. Clamping blocks 222 are provided at the opposite ends of the top of the left long plate 215 and the right long plate 216.

[0037] In one specific embodiment, please refer to Figure 2 The rotation of the micro motor 111 drives the gear 210, and the rotation of the gear 210 meshes with the upper rack 219 and the lower rack 220. Since the upper rack 219 and the lower rack 220 are connected to the left connecting plate 217 and the right connecting plate 218 respectively by pins, and the left moving base 213 and the right moving base 214 slide close to each other along the support rod 212, the racks are inserted into the slot 221 to maintain stability during the transmission. When the moving base drives the long plate close to each other, the two clamping blocks 222 close to each other, thereby clamping the stator. The fixed boss 211 is used to fix both sides of the support rod 212.

[0038] Please see Figure 3 The lifting device 300 includes a vertically arranged mounting plate 310. A threaded rod 311 is provided in the middle of the mounting plate 310 and passes through its top end to connect to the output end of the motor 312. Guide rods 313 are provided on both sides of the threaded rod 311. A lifting block 314 is threadedly connected to the threaded rod 311 and the guide rods 313. The front connection dimension of the lifting block 314 is larger than the square plate 110 of the lifting block 314.

[0039] In one specific embodiment, please refer to Figure 3 By starting the motor 312, the motor 312 drives the rotation of the threaded rod 311, causing the lifting block 314 outside the threaded rod 311 to move along the thread of the threaded rod 311 and slide up and down with the guide rod 313. The guide rod 313 is used to limit the rotation of the lifting block 314, so that the lifting block 314 maintains stable movement. The lifting of the lifting block 314 drives the square plate 110 to move synchronously.

[0040] Please see Figure 3 The mounting plate 310 is located at the top of the desktop 400. Support legs 410 are provided at the four corners of the desktop 400. The stator housing 411 is provided at the top of the desktop 400 at the corresponding position of the clamping block 222. The stator housing 411 has a positioning groove 412 inside.

[0041] In one specific embodiment, please refer to Figure 3 The desktop 400 provides support for the mounting plate 310 and the stator housing 411, the support leg 410 provides height and stability for the desktop 400, and the stator housing 411 has a positioning groove 412 to facilitate the stability of the stator and avoid displacement caused by other reasons.

[0042] Please see Figure 2 Each clamping block 222 has a reinforcing block 223 on its back side, and each clamping block 222 has a rubber pad on its opposite end.

[0043] In one specific embodiment, please refer to Figure 2 The structural strength of the clamping block 222 and the left and right long plates is increased by the reinforcing block 223, and the rubber pad increases the friction between the clamping block 222 and the stator to prevent slippage.

[0044] Please see Figure 3 The threaded rod 311 is fitted with a bearing sleeve on the outside of the mounting plate 310, and the stator housing 411 consists of three in a row.

[0045] In one specific embodiment, please refer to Figure 3 By using a bearing sleeve, friction and wear between the threaded rod 311 and the mounting plate 310 are reduced, ensuring stable operation of the threaded rod 311.

[0046] Please see Figure 3 A switch panel 413 is provided on one side of the top of the desktop 400. A micro motor switch and a motor switch are respectively provided on the top of the switch panel 413. The switch panel 413 is electrically connected to an external power supply.

[0047] In one specific embodiment, please refer to Figure 3 The device is connected to an external power supply via the switch panel 413, and the independent switch provides independent protection for the electrical equipment.

[0048] This utility model provides a flipping device for processing the stator of a three-phase asynchronous motor, and its specific usage is as follows:

[0049] Before use: Connect the external power supply through the switch panel 413, open the switch panel 413, and then turn on the micro motor switch and the motor switch in sequence. Place the stator into the positioning groove 412 inside the stator housing 411.

[0050] In use: The motor 312 drives the rotation of the threaded rod 311, causing the lifting block 314 outside the threaded rod 311 to move along the thread of the threaded rod 311 and slide down with the guide rod 313. The guide rod 313 is used to limit the rotation of the lifting block 314, so that the lifting block 314 maintains stable movement. The lifting of the lifting block 314 drives the square plate 110 synchronously. When the lifting block 314 descends to the height that can clamp the stator, the rotation of the micro motor 111 drives the gear 210. The rotation of the gear 210 will mesh with the upper rack 219 and the lower rack 220. Since the upper rack 219 and the lower rack 220 are respectively connected to the left connecting plate 217 and the right connecting plate 220 by pins. When the plates 218 are connected and the left movable base 213 and the right movable base 214 slide close to each other along the support rod 212, the rack passes through the slot 221 to maintain stability during transmission. When the movable base drives the long plates to move closer to each other, the two clamping blocks 222 move closer to each other, thereby clamping the stator. When the stator is flipped, the motor 312 drives the threaded rod 311 to rotate in the opposite direction, causing the lifting block 314 to rise. When the micro motor 111 starts to rotate, the rotation of the output end will drive the horizontal plate 112 to move synchronously. The rotation of the horizontal plate 112 will drive the limiting rod 113 to rotate inside the limiting groove 115, thereby keeping the horizontal plate 112 in a stable rotation.
