[0002] Permanent magnet motors generate their magnetic field using permanent magnets, eliminating the need for excitation coils and current. This results in higher efficiency and power factor, while reducing energy consumption and operating costs in production. Furthermore, permanent magnet motors are simple in structure, highly reliable, and less demanding in terms of environment, operating in harsh conditions such as high and low temperatures, humidity, and dust. This makes them widely applicable across various industries and fields. Therefore, refurbishing three-phase asynchronous motors into permanent magnet motors has significant development potential. Currently, disassembling three-phase asynchronous motors requires workers to remove the end covers and rotor, but this process is time-consuming, labor-intensive, and inefficient due to the chaotic operating environment and the difficulty of disassembly.

[0009] A storage box is located below the workbench and corresponds to the material discharge hole; the storage box is used to store the disassembled rotor.

[0010] In one possible implementation, the first mounting position is located at one end of the workbench, and the workbench has two grooves located on both sides of the first mounting position, the grooves corresponding to the first mounting position; the grooves are for workers to enter to perform end cap removal operations.

The first mounting position and the second mounting position are both located on the tabletop, and the operating seat is slidably connected to the tabletop. The material discharge hole and the groove are both formed on the tabletop. The storage box is located below the tabletop and between the two legs.

[0012] In one possible implementation, the worktable is provided with two slide rails, and the two ends of the slide rails are respectively located in the first mounting position and the second mounting position; the lower end of the operating seat is provided with two sets of sliders that are slidably connected to the two slide rails respectively.

[0013] In one possible implementation, the operating seat is provided with two mounting slots, mounting holes formed on the bottom surface of the mounting slots, and two cover plates. The two mounting slots correspond one-to-one with the two sets of sliders. The mounting holes are arranged coaxially with the screw holes on the sliders and are fixedly connected by bolts.

The operator first removes the end cover of the three-phase asynchronous motor and rotates the outer shell of the three-phase asynchronous motor to a vertical position, with the center of the outer shell corresponding vertically to the through hole on the operating seat. Then, the operating seat and the outer shell are pushed together to the second mounting position on the workbench, with the outer shell located below the pushing mechanism and the through hole aligned with the discharge hole. The pushing mechanism is activated to move its free end downward, and the free end acts on the end of the rotor shaft, causing the entire rotor to move downward and detach from the outer shell.

In this way, the arrangement of the first and second mounting positions allows the disassembly of the motor to be carried out in two steps: end cover removal and rotor removal. This makes the operating environment neat and orderly, and the push mechanism accurately and quickly pushes the rotor out of the housing, making the disassembly of the motor easier and less labor-intensive, and improving disassembly efficiency.

[0033] Please see Figures 1 to 6The disassembly and assembly device for converting a three-phase asynchronous motor into a permanent magnet motor, provided by this utility model, will now be described. A disassembly and assembly device for converting a three-phase asynchronous motor into a permanent magnet motor includes a support frame 10, a pushing mechanism 20, a worktable 30, an operating seat 40, and a storage box 50. The support frame 10 has a mounting part 11 and an operating space 12 located below the mounting part 11. The pushing mechanism 20 is fixedly mounted on the mounting part 11, and the free end of the pushing mechanism 20 is located within the operating space 12. The worktable 30 is located within the operating space 12. The worktable 30 has a first mounting position 31 for removing the end cover and a second mounting position 32 for removing the rotor. The second mounting position 32 is located directly below the pushing mechanism 20 and has a discharge hole 33. The operating seat 40 is slidably connected to the worktable 30 and is used to be positioned on the first mounting position 31 and the second mounting position 32. The operating seat 40 has a through hole 41 for the rotor to pass through. The storage box 50 is located below the worktable 30 and corresponds to the discharge hole 33. The storage box 50 is used to store the disassembled rotor.

[0034] The present invention provides a disassembly and assembly device for converting a three-phase asynchronous motor into a permanent magnet motor. Compared with the prior art, when it is necessary to disassemble and assemble a three-phase asynchronous motor into a permanent magnet motor, the operating seat 40 is located on the first mounting position 31 on the workbench 30. A crane or similar device is used to place the three-phase asynchronous motor to be disassembled onto the operating seat 40. The operator first removes the end cover of the three-phase asynchronous motor and rotates the outer shell of the three-phase asynchronous motor to a vertical position, with the center of the outer shell corresponding vertically to the through hole 41 on the operating seat 40. Then, the operating seat 40 and the outer shell are pushed together to the second mounting position 32 on the workbench 30, with the outer shell located below the pushing mechanism 20 and the through hole 41 aligned with the discharge hole 33. The pushing mechanism 20 is activated to move its free end downward, and the free end acts on the end of the rotor shaft, causing the entire rotor to move downward and detach from the outer shell. The rotor passes through the through hole 41 and the discharge hole 33 and enters the storage box 50. In this way, the arrangement of the first mounting position 31 and the second mounting position 32 allows the disassembly of the motor to be carried out in two steps: end cover removal and rotor removal. This makes the operating environment neat and orderly. Furthermore, the push mechanism 20 accurately and quickly pushes the rotor out of the housing, making the disassembly of the motor easier and less labor-intensive, and improving the disassembly efficiency.

[0035] To ensure the efficiency and stability of the entire disassembly and assembly process, the push mechanism 20 employs an advanced hydraulic drive system. This hydraulic drive system can precisely control the moving speed and pressure of the free end of the push mechanism 20, avoiding unnecessary damage to the motor components during disassembly. Simultaneously, the surfaces of the worktable 30 and the operating seat 40 have undergone special anti-slip treatment to prevent the motor from slipping during operation, thus improving operational safety.

[0036] In addition, when using this disassembly and assembly device for installation, the operation is performed in reverse. That is, the rotor is first installed at the second mounting position 32 by using the pushing mechanism 20 to push the rotor into the housing, and then the operating seat 40 and the housing are moved to the first mounting position 31 to install the end cover.

[0037] Please see Figures 1 to 3 As a specific embodiment of the disassembly and assembly device for converting a three-phase asynchronous motor into a permanent magnet motor provided by this utility model, the first mounting position 31 is set at one end of the workbench 30, and two grooves 34 are respectively located on both sides of the first mounting position 31 on the workbench 30, the grooves 34 corresponding to the first mounting position 31; the grooves 34 are used for workers to enter to perform end cap disassembly operations; by arranging the first mounting position 31 at one end of the workbench 30, and by setting inwardly recessed grooves 34 on both sides of the workbench 30, the workers can stand in the grooves 34 on both sides of the workbench 30 and get closer to the operating seat 40 on the first mounting position 31, thereby performing operations conveniently and accurately. A tool rack is also provided on one side of the workbench 30, and the tool rack has multiple tool placement slots of different sizes, which makes it convenient for workers to neatly place various tools required for disassembling the end cap, such as screwdrivers, wrenches, etc., for easy access and to avoid tools being lost or affecting operational efficiency due to random placement.

A material discharge hole 33 and a groove 34 are both formed on the table plate 35. A storage box 50 is located below the table plate 35 and between the two support legs 36. That is, the workbench 30 has an inverted U-shaped structure, with the table plate 35 arranged horizontally and the support legs 36 on both sides arranged vertically, thus forming a stable workbench 30. The first mounting position 31 and the second mounting position 32 are both arranged on the table plate 35. The storage box 50 is located below the table plate 35 and between the two support legs 36.

When it is necessary to move the operating seat 40 to the first mounting position 31 and the second mounting position 32, simply push the operating seat 40 gently, and the sliders 38 will slide smoothly on the slide rails 37 until the operating seat 40 accurately reaches the first mounting position 31 or the second mounting position 32. Stops 47 are provided at the first mounting position 31 and the second mounting position 32 to prevent the operating seat 40 from moving too far.

The two cover plates 44 are respectively installed in the two mounting slots 42. During installation, the cover plates 44 are first opened so that the two sets of sliders 38 correspond vertically to the mounting slots 42. Then, bolts are used to thread the mounting holes 43 and the screw holes on the sliders 38 to achieve a fixed connection between the operating seat 40 and the sliders 38. Finally, the cover plates 44 are sealed in the mounting slots 42. In this way, the upper surface of the operating seat 40 is flat, which facilitates the disassembly of the motor.
