Description

Technical Field

[0001] The invention relates to the field of motor assembly equipment, in particular to a hollow shaft rotor and stator assembly guide device. Background Art

[0002] The motor mainly includes a stator and a rotor installed inside the stator, wherein the rotor includes a mounting portion for mounting a permanent magnet and a rotating shaft for outputting work to the outside. The hollow shaft rotor is a type of rotor, which is characterized by an inner hole opened along the axial direction of the rotor shaft for passing gas, liquid and other media, and is widely used in automated processing, medical equipment and other fields.

[0003] Both ends of the stator along the axial direction are provided with limiting structures, such as end covers, bearings, etc., which are used to support the rotation of the rotor and limit the rotor along the axial direction of the rotor. In the process of assembling the stator and the rotor, the limiting structure at one end of the stator is usually installed first, and then the rotor is placed into the stator from the other end of the stator. During installation, one end of the rotor shaft needs to pass through the through hole on the end cover. The stator initially supports the rotor through the installed end cover. At this time, the rotor shaft is coaxial with the inner circle of the stator. Finally, the limiting structures such as the bearings and end covers on the other side of the stator are installed, and the assembly of the stator and the rotor is completed.

[0004] With respect to the above-mentioned related technologies, the fitting clearance between the stator and the rotor is extremely small. For the surface-mounted permanent magnet motor, the permanent magnet steel on the rotor is located on the outer circle of the rotor mounting part. Due to the magnetic attraction of the magnet steel, when assembling the rotor and the stator, the rotor is easily adsorbed to the inner circle side wall of the stator under the action of the magnetic force. Dragging the rotor not only easily damages the coating on the surface of the magnet steel, but also when the magnet steel is damaged due to collision, the magnet steel on the inner ring of the stator needs to be disassembled. It takes time to clean up the magnet steel fragments and re-assemble the rotor, which affects the assembly efficiency of the stator and the rotor. Summary of the invention

[0005] In order to improve the working efficiency when assembling a rotor and a stator, the present application provides a hollow shaft rotor and a stator assembly guide device.

[0006] The present application provides a hollow shaft rotor and stator assembly guide device, which adopts the following technical solution: A hollow shaft rotor and stator assembly guide device, comprising a positioning base, a positioning hole is opened in the vertical direction of the positioning base, a positioning guide is provided in the positioning base, an end cover is installed on the side of the stator facing the positioning base, when the stator is placed on the positioning base, the positioning guide guides and positions the stator so that the stator and the positioning hole are coaxial; a handling member, comprising a suspension rod and a suspension plate, the diameter of the suspension rod is smaller than the inner hole diameter of the rotor shaft, when assembling the stator and the rotor, the suspension rod is passed through the inner hole of the rotor shaft, the suspension rod is arranged vertically when working, the suspension plate is detachably connected to the upper end of the suspension rod, the rotor is located below the suspension plate, and the upper end of the suspension rod is A connecting piece is provided at the part, which is used to push the hanger plate to fit together with the rotor shaft; a guide column is located at the end of the hanger rod away from the hanger plate and is coaxial with the hanger rod. The hanger plate and the guide column cooperate to clamp and position the end of the rotor axis. A coaxial positioning piece is provided at the end of the guide column close to the hanger rod. When the positioning piece is located in the inner hole of the rotor shaft, the guide column and the rotor shaft remain coaxial. When the guide column passes through the positioning hole, it is coaxial with the positioning hole and guides the rotor into the stator to complete the assembly; a hanging piece is arranged above the positioning base, and is used to move the hanger plate and the hanger rod horizontally and vertically. The moving trajectory of the hanger rod passes directly above the positioning hole.

[0007] By adopting the above technical solution, after installing the end cover at one end of the stator, the stator is placed on the positioning base, the positioning base supports the stator, and the positioning guide guides the stator so that the inner circle of the stator is coaxial with the positioning hole. The rotor is arranged vertically, and another set of end covers and bearing components are installed on the upper end of the rotor shaft. The suspension rod passes through the inner hole of the rotor shaft, and the guide column is fitted with the end of the rotor shaft away from the end cover. At this time, the positioning member is inserted into the inner hole of the rotor shaft and fits with the inner wall of the inner hole, so that the guide column and the rotor shaft are coaxial. At this time, the suspension rod presses the suspension plate to the end of the rotor shaft away from the guide column through the connecting member, and the suspension plate, suspension rod and guide column are lifted by the lifting member, so that the guide column and the suspension rod cooperate to lift the rotor, and the lifting member moves the rotor to the top of the positioning base. After that, lower the suspension rod and the rotor. The guide column first enters the inner circle of the stator, and passes through the through hole of the end cover below the stator to enter the positioning hole of the positioning base. The positioning base guides the guide column through the positioning hole, so that the guide column and the suspension rod cooperate to guide the rotor into the inner circle of the stator. The guide column limits the rotor through the positioning piece and the lifting plate to reduce the probability of the rotor being deflected when entering the inner circle of the stator. After the assembly of the rotor and the stator is completed, the end cover above the rotor is installed on the stator to complete the assembly of the stator and the rotor. After the assembly is completed, the suspension rod and the guide column are disassembled. When assembling the stator and the rotor, through the cooperation of the suspension rod, the guide column and the positioning base, the lateral displacement of the rotor is limited in the process of keeping the rotor and the stator coaxial, which is conducive to reducing the probability of collision between the magnetic steel of the rotor mounting part and the inner circle of the stator, thereby improving the assembly efficiency of the stator and the rotor.

[0008] Optionally, a support platform is fixedly provided at the lower end of the positioning base, and a rotor support plate is provided on the side of the support platform away from the positioning base. The moving trajectory of the boom passes directly above the rotor support plate. The rotor support plate is used to support the rotor and keep the rotor in a vertical state. The rotor support plate is vertically opened with an avoidance opening adapted to the guide column. A transport seat is provided at the lower end of the support platform, and the moving trajectory of the transport seat coincides with the moving trajectory of the frame. A clamping claw which reciprocates vertically is provided at the upper end of the transport seat, and the clamping claw is used to clamp the guide column. The transport seat is also provided with a disassembly and assembly mechanism for disassembling or assembling the guide column and the boom.

[0009] By adopting the above technical solution, the support platform supports the transport seat. In the initial state, the transport seat is directly below the rotor support plate, and the guide column is clamped and positioned by the clamping claw. At this time, the guide column is coaxial with the rotor support plate. The rotor is placed on the rotor support platform, and the rotor shaft passes through the avoidance port. After the rotor support platform supports the rotor, the rotor shaft is coaxial with the avoidance port, and the bearing, end cover and other components are installed on the upper end of the rotor shaft. The suspension rod is passed through the inner hole of the rotor shaft from top to bottom, so that the suspension plate contacts the upper end surface of the rotor shaft. At this time, the clamping claw drives the guide column to enter the avoidance port. When the positioning piece at the upper end of the guide column enters the inner hole of the rotor shaft, the guide column is assembled to the suspension rod through the disassembly mechanism. No manual work is required when assembling and disassembling the suspension rod and the guide column, which is conducive to further improving the convenience of assembling the rotor and the stator.

[0010] Optionally, a disassembly groove is provided at the lower end of the guide column, a rotating disk is provided in the disassembly groove, a threaded rod is coaxially fixed to the end of the rotating disk close to the suspension rod, a threaded hole matching the threaded rod is provided at the end of the suspension rod away from the suspension plate, the threaded rod passes through the guide column and cooperates with the threaded hole, a limit ring is provided in the disassembly groove, the limit ring is located on the side of the rotating disk away from the suspension rod, and is used to limit the axial displacement of the rotating disk in the disassembly groove.

[0011] By adopting the above technical solution, when the rotating disk is rotated, the rotating disk drives the threaded rod to rotate, and when the threaded rod is disengaged from the threaded hole, the guide column is separated from the suspension rod. The disassembly groove is used to avoid the disassembly mechanism, which is convenient for the disassembly mechanism to rotate the rotating disk. At the same time, the limit ring limits the displacement range of the rotating disk along the axial direction, thereby preventing the threaded rod from being completely disengaged from the guide column, reducing the probability of losing the threaded rod.

[0012] Optionally, the disassembly and assembly mechanism includes a vertical moving frame, a disassembly rod, a rotating part and a positioning spring. The vertical moving frame is vertically slidably connected to the transport seat, the clamping claw is located at the upper end of the vertical moving frame and moves synchronously with the vertical moving frame, and a lifting cylinder for pushing the vertical moving frame to move is fixed at the lower end of the vertical moving frame. The disassembly and assembly rod is vertically arranged at the upper end of the vertical moving frame and is rotatably connected to the vertical moving frame laterally. The rotating part is fixedly connected to the vertical moving frame, and is used to drive the disassembly and assembly rod to rotate around its own axis. The upper end of the disassembly and assembly rod is slidably connected to a polygonal plate along the axial direction. The positioning spring is located between the polygonal plate and the disassembly and assembly rod, and is used to push the polygonal plate away from the vertical moving frame. A disassembly groove adapted to the disassembly and assembly plate is provided at the lower end of the rotating disk.

[0013] By adopting the above technical scheme, the transport seat supports the vertical moving frame, and when the lifting cylinder drives the vertical moving frame to move, the vertical moving frame drives the clamping claw and the disassembly rod to move. When assembling or disassembling the guide column, the disassembly rod drives the polygonal plate to enter the disassembly groove. When the polygonal plate conflicts with the rotating disk, the rotating part drives the disassembly rod to rotate. When the polygonal plate is opposite to the disassembly groove, the polygonal plate directly drives the rotating disk to rotate. When the polygonal plate is not opposite to the disassembly groove, the polygonal plate conflicts with the rotating disk, and the positioning spring is deformed, which also makes the rotating part drive the polygonal plate to rotate. When the polygonal plate is opposite to the disassembly groove, the positioning spring pushes the polygonal plate into the disassembly groove, which is beneficial to improve the convenience of disassembling or assembling the guide column.

[0014] Optionally, a guide cylinder is provided at the upper end of the rotor support disk, which is coaxial with the avoidance opening and is used to guide the rotor shaft to enter the avoidance opening. A plurality of support blocks are provided along the circumferential direction at the upper end of the rotor support disk. When the rotor shaft is located in the avoidance opening, the support blocks support the end surface of the rotor mounting portion close to the support platform.

[0015] By adopting the above technical solution, when placing the rotor on the rotor support plate, the guide cylinder guides and limits the rotor shaft to accurately locate the initial position of the rotor, and the mounting part of the rotor is supported by the support block, which is beneficial to improving the placement stability of the rotor.

[0016] Optionally, the connecting member includes a screw rod and a positioning nut, wherein the screw rod is coaxially fixed to the suspension rod and passes through the suspension plate, and the positioning nut is located on a side of the suspension plate away from the suspension rod and is threadedly connected to the screw rod.

[0017] By adopting the above technical solution, the screw rod cooperates with the inner wall of the through hole to limit the position of the hanging plate, and the positioning nut cooperates with the hanging rod to limit the displacement of the hanging plate along the axis of the screw rod, so that the hanging plate fits with the rotor shaft.

[0018] Optionally, the positioning guide member includes a plurality of guide rods, which are parallel to each other and arranged vertically. The support platform is provided with a lifting platform for driving all the guide rods to move vertically. The end cover has a plurality of mounting holes opened vertically. The guide rods correspond to the mounting holes one by one. All the guide rods pass through the corresponding mounting holes and fit against the inner walls of the mounting holes.

[0019] By adopting the above technical solution, after the stator is placed on the positioning base, the lifting platform drives all the guide rods to rise, and then the guide rods pass through the corresponding installation holes, thereby realizing the positioning of the stator, making the axis of the inner circle of the stator coaxial with the axis of the positioning hole. At the same time, when placing the rotor, the guide rods also cooperate with the end cover on the rotor to guide the rotor, thereby further improving the accuracy of the assembly of the rotor and the stator.

[0020] Optionally, the diameter of the guide column is not larger than the diameter of the boom, and the positioning member includes a plurality of abutment blocks, which are slidably connected to the guide column along the radial direction of the guide column, and the guide column is provided with a driving member for driving all the abutment blocks to move. The guide column is also provided with a plurality of abutment plates along the circumference, and all the abutment plates are located at the lower end of the guide column. The plurality of abutment plates are evenly arranged along the circumference of the guide column, and all the abutment plates are hinged to the guide column vertically, and the driving member drives the abutment plates to rotate, and the abutment plates rotate closer to or away from the rotor shaft, and an annular groove for avoiding the abutment plates is provided on the inner wall of the positioning hole.

[0021] By adopting the above technical solution, the movement of the hanger directly drives the guide column to move. When the hanger passes through the rotor shaft, the guide column passes through the rotor shaft first, and all the abutment blocks are in the channel of the rotor shaft, and all the abutment plates are located below the rotor shaft. At this time, all the abutment blocks are driven by the driving member to approach the inner wall of the rotor shaft, and then the guide column is adjusted to a coaxial state with the rotor shaft. At this time, the driving rod also pushes the abutment plate to approach the lower end surface of the rotor shaft, so that the hanger plate and the abutment plate cooperate to clamp and position the rotor shaft. The guide column does not need to be disassembled, which further improves the convenience of assembling the hanger and the rotor.

[0022] Optionally, the driving member includes a threaded column, a driving block 1 and a driving block 2. The guide column is hollow, the threaded column is parallel to the guide column and is rotatably connected, the threaded column is divided into a screw 1 and a screw 2 from top to bottom along the axial direction, the pitch of the screw 1 and the screw 2 are different, the driving block 1 and the driving block 2 are both slidingly connected to the guide column along the axial direction of the guide column, the screw 1 passes through the driving block 1 and is threadedly connected to the driving block 1, the screw 2 passes through the driving block 2 and is threadedly connected to the driving block 2, all the abutment blocks are vertically hinged with a push rod 1, the end of the push rod 1 away from the abutment block is hinged to the driving block 1, all the abutment plates are vertically hinged with a push rod 2, and the push rod 2 is vertically hinged to the driving block 2.

[0023] By adopting the above technical solution, under the support of the guide column, when the threaded column is rotated, the lead screw 1 and the lead screw 2 both drive the corresponding drive block 1 and the drive block 2 to move, and the moving distances of the drive block 1 and the drive block 2 are different. When the drive block 1 moves, it drives the abutment block to move through the push rod 1, and when the drive block moves, it drives the abutment plate to move through the push rod 2.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. After installing the end cover on one end of the stator, place the stator on the positioning base. The positioning base supports the stator, and the positioning guide guides the stator so that the inner circle of the stator is coaxial with the positioning hole. Set the rotor vertically, install another set of end covers and bearing components to the upper end of the rotor shaft, pass the hanger through the inner hole of the rotor shaft, and make the guide column fit with the end of the rotor shaft away from the end cover. At this time, the positioning piece is inserted into the inner hole of the rotor shaft and fits with the inner wall of the inner hole, so that the guide column and the rotor shaft are coaxial. At this time, the hanger presses the hanger plate to the end of the rotor shaft away from the guide column through the connecting piece, and lifts the hanger plate, hanger and guide column through the lifting piece, so that the guide column and the hanger cooperate to lift the rotor, and the lifting piece moves the rotor to the top of the positioning base. After that, lower the suspension rod and the rotor. The guide column first enters the inner circle of the stator, and passes through the through hole of the end cover below the stator to enter the positioning hole of the positioning base. The positioning base guides the guide column through the positioning hole, so that the guide column and the suspension rod cooperate to guide the rotor into the inner circle of the stator. The guide column limits the rotor through the positioning piece and the lifting plate to reduce the probability of the rotor being deflected when entering the inner circle of the stator. After the rotor and stator are assembled, the end cover above the rotor is installed on the stator to complete the assembly of the stator and the rotor. After the assembly is completed, the suspension rod and the guide column are disassembled. When assembling the stator and the rotor, through the cooperation of the suspension rod, the guide column and the positioning base, the lateral displacement of the rotor is limited in the process of keeping the rotor and the stator coaxial, which is beneficial to reduce the probability of collision between the magnetic steel of the rotor mounting part and the inner circle of the stator, thereby improving the assembly efficiency of the stator and the rotor; 2. The support platform supports the transport seat. In the initial state, the transport seat is directly below the rotor support plate, and the guide column is clamped and positioned by the clamp. At this time, the guide column is coaxial with the rotor support plate. The rotor is placed on the rotor support platform, and the rotor shaft passes through the avoidance opening. After the rotor support platform supports the rotor, the rotor shaft is coaxial with the avoidance opening, and the bearings, end covers and other components are installed on the upper end of the rotor shaft. The suspension rod is passed through the inner hole of the rotor shaft from top to bottom, so that the suspension plate contacts the upper end surface of the rotor shaft. At this time, the clamp drives the guide column into the avoidance opening. When the positioning piece at the upper end of the guide column enters the inner hole of the rotor shaft, the guide column is assembled to the suspension rod through the disassembly mechanism. No manual work is required when assembling and disassembling the suspension rod and the guide column, which is conducive to further improving the convenience of assembling the rotor and the stator.

[0035] Reference Figure 1 and Figure 2 The positioning base 1 is provided with a positioning hole 11 in the vertical direction. Before assembling the stator 10 and the rotor 20, the end cover on one side of the stator 10 is installed. The stator 10 is placed on the positioning base 1 so that the side of the stator 10 where the end cover is installed contacts the positioning base 1. The positioning base 1 is provided with a positioning guide, which includes a plurality of guide rods 121 arranged vertically.

A lifting platform 54 is installed at the lower end of the support platform 5. The lifting platform 54 moves back and forth vertically. The support platform 5 is provided with a cylinder for driving the lifting platform 54 to move. All guide rods 121 are arranged at the upper end of the lifting platform 54.

[0036] Reference Figure 1 and Figure 2 When placing the stator 10, the lifting platform 54 is operated to drive all the guide rods 121 to rise. The end cover on the stator 10 is provided with mounting holes, and the guide rods 121 correspond to the mounting holes one by one. When placing the stator 10, the guide rods 121 are sequentially passed through the corresponding mounting holes and fit with the inner walls of the mounting holes. At this time, all the guide rods 121 cooperate to limit the stator 10. The positioning base 1 is provided with a positioning hole 11 in the vertical direction. When the stator 10 is positioned, the positioning hole 11 is coaxial with the positioning inner circle.

[0037] Reference Figure 1 and Figure 3 , a plurality of support blocks 512 are fixedly provided at the upper end of the rotor support disk 51 along the circumferential direction, and an escape opening is opened along the axial direction. When the rotor 20 is placed on the rotor support disk 51, the rotating shaft of the rotor 20 is located between all the support blocks 512, and the rotating shaft of the rotor 20 is located in the escape opening. The upper end surface of the support block 512 abuts against the lower end surface of the mounting portion of the rotor 20, thereby supporting the rotor 20 and making the rotor 20 in a vertical state. A guide cylinder 511 is provided at the upper end of the rotor support disk 51. The guide cylinder 511 is hollow and coaxial with the escape opening. The inner diameter of the guide cylinder 511 matches the outer diameter of the rotating shaft of the rotor 20.

The guide cylinder 511 limits and guides the rotating shaft of the rotor 20, so that the rotating shaft of the rotor 20 is coaxial with the escape opening.

[0038] Reference Figure 1 and Figure 3The transport member 2 includes a suspension rod 21 and a suspension plate 22. A connecting member 23 is provided at one end of the suspension rod 21 along the length direction. The connecting member 23 includes a screw 231 and a positioning nut 232. The screw 231 is coaxially fixed with the suspension rod 21, and the end of the screw 231 close to the suspension rod 21 is a bare rod. The suspension rod 21 is provided with a through hole adapted to the bare rod portion of the screw 231, and the screw 231 passes through the suspension plate 22 along the through hole. The positioning nut 232 is threadedly connected to the screw 231, and the suspension plate 22 is located between the positioning nut 232 and the suspension rod 21. The thickness of the suspension plate 22 is greater than the length of the bare rod portion of the screw 231, and when the positioning nut 232 is tightened, the positioning nut 232 pushes the suspension plate 22 to fit with the suspension rod 21.

[0039] Reference Figure 1 and Figure 3 In this embodiment, the hoisting member 4 is a crane. In other embodiments, the hoisting member 4 can also be a crane or other mechanism that can carry objects vertically and horizontally. There is no limitation here. The crane is set at the upper end of the support platform 5 and is provided with a cable for hoisting objects. The upper end of the hanging plate 22 is fixed with a lifting lug for connecting the cable. When the crane is working, the cable and the lifting lug cooperate to drive the hanging plate 22 and the hanging rod 21 to move.

[0040] Reference Figure 1 and Figure 3 In the initial state, the suspension rod 21 is directly above the rotor 20, and the end of the suspension rod 21 away from the suspension plate 22 is directly opposite to the rotor 20. Another set of end covers and bearings on the stator 10 are installed to the upper end of the rotor 20 shaft. At this time, the suspension rod 21 is driven downward by the hanging member 4, so that the lower end of the suspension rod 21 passes through the channel of the rotor 20 shaft, and the lower end of the suspension rod 21 is in the avoidance opening.

[0041] Reference Figure 1 and Figure 3 The lower end of the hanging plate 22 is fixed with a truncated cone that matches the inner hole of the rotating shaft of the rotor 20. The truncated cone is located in the inner hole of the rotating shaft of the rotor 20, so that the hanging rod 21 is coaxial with the rotating shaft of the rotor 20. At the same time, the lower end of the hanging plate 22 contacts the end cover above the rotor 20, thereby limiting the end cover.

[0042] Reference Figure 1 and Figure 3 The guide column 3 is a cylinder. In this embodiment, the diameter of the guide column 3 is larger than the outer diameter of the inner hole of the rotor shaft 20, and the outer diameter of the guide column 3 is matched with the inner diameter of the positioning hole 11. A disassembly groove 332 is provided at one end of the guide column 3 along the axial direction, and a rotating disk 33 is provided in the disassembly groove 332. The rotating disk 33 is slidably connected with the guide column 3 along the axial direction of the guide column 3. A threaded rod 331 is coaxially fixed at one end of the rotating disk 33, and a round hole matched with the threaded rod 331 is provided at the guide column 3.

[0043] Reference Figure 1and Figure 3 A stop ring 321 is also provided in the disassembly groove 32. The stop ring 321 is located on the side of the rotating disk 33 away from the threaded rod 331. The stop ring 321 cooperates with the guide column 3 to limit the displacement of the rotating disk 33 along the axial direction, so that the rotating disk 33 is always in the disassembly groove 32. A disassembly groove 332 is provided at one end of the rotating disk 33 away from the threaded rod 331. In this embodiment, the disassembly groove 332 is a cross groove, and the rotating disk 33 is easily rotated through the disassembly groove 332.

[0044] Reference Figure 1 and Figure 3 The lower end of the support platform 5 is connected to a transport seat 52 in a lateral sliding manner. The moving trajectory of the transport seat 52 is the same as the moving trajectory of the lifting member 4 in the lateral direction. In the initial state, the transport seat 52 is located directly below the rotor support plate 51. A disassembly and assembly mechanism is provided at the upper end of the transport seat 52. The disassembly and assembly mechanism includes a vertical moving frame 531, a disassembly and assembly rod 532, a rotating member 533 and a positioning spring 534. The vertical moving frame 531 is slidably connected to the transport seat 52 in the vertical direction. When the transport seat 52 moves, it drives the vertical moving frame 531 to move. A lifting cylinder for driving the vertical moving frame 531 to move is installed at the lower end of the transport seat 52. A clamping claw 521 is installed at the upper end of the vertical moving frame 531. The clamping claw 521 opens and closes in the lateral direction. In the initial state, the guide column 3 is located at the upper end of the vertical moving frame 531, and the guide column 3 is clamped by the clamping claw 521. At this time, the end of the guide column 3 with a circular hole is vertically facing upward.

[0045] Reference Figure 1 and Figure 3 The disassembly rod 532 is arranged vertically and is rotatably connected with the vertical moving frame 531. When the vertical moving frame 531 moves, the disassembly rod 532 is driven to be rotatably connected. The rotating member 533 is installed at the lower end of the vertical moving frame 531 to drive the disassembly rod 532 to rotate. When the clamping claw 521 holds the guide column 3 tightly, the disassembly rod 532 is located in the disassembly groove 32 and is coaxial with the guide column 3. The upper end of the disassembly rod 532 is slidably connected with a polygonal plate 535 along the axial direction, and the polygonal plate 535 is adapted to the disassembly groove 332. The positioning spring 534 is located between the polygonal plates 535, and one end of the positioning spring 534 is fixedly connected to the polygonal plate 535, and the other end is fixedly connected to the disassembly rod 532. When the positioning spring 534 is in a natural state, it applies an upward thrust to the polygonal plate 535.

[0046] Reference Figure 1 and Figure 3When placing the guide column 3, if the polygonal plate 535 is not directly opposite to the disassembly groove 332, the polygonal plate 535 and the disassembly rod 532 slide relative to each other along the axial direction, and the positioning spring 534 is in a deformed state. After the clamping plate presses the suspension rod 21 through the pressure wheel, the vertical moving frame 531 drives the guide column 3 to move upward, so that the guide column 3 enters the avoidance groove and approaches the suspension rod 21. The lower end of the suspension rod 21 is provided with a threaded hole 211 adapted to the threaded rod 331. When the guide column 3 contacts the lower end of the rotating shaft of the rotor 20, the upper end of the threaded rod 331 contacts the suspension rod 21, and the threaded rod 331 faces the threaded hole 211.

[0047] Reference Figure 1 and Figure 3 , a positioning member 31 is provided at the upper end of the guide column 3. In this embodiment, the positioning member 31 is a circular ring, and the outer diameter of the circular ring is adapted to the inner diameter of the rotating shaft of the rotor 20. After the guide column 3 contacts the rotating shaft of the rotor 20 under the action of the vertical moving frame 531, the positioning member 31 enters the inner hole of the rotating shaft of the rotor 20 and fits with the inner wall of the inner hole. At this time, the guide column 3 is coaxial with the rotating shaft of the rotor 20. The guide column 3 contacts the rotating shaft of the rotor 20, and the rotating member 533 drives the disassembly rod to rotate. When the polygonal plate 535 rotates to an angle directly opposite to the disassembly groove 332, the positioning spring 534 pushes the polygonal plate 535 into the disassembly groove 332. At this time, the polygonal plate 535 drives the rotating disk 33 and the threaded rod 331 to rotate.

[0048] Reference Figure 1 and Figure 3 , the threaded rod 331 gradually enters the threaded hole 211 when it rotates. When the upper end of the rotating disk 33 contacts the guide column 3, the guide column 3 is pushed to contact the rotating shaft of the rotor 20. At this time, the guide column 3 cooperates with the hanging plate 22 to clamp the rotor 20 vertically. The clamping jaws 521 are operated to release the clamping of the guide column 3 and reset the vertical displacement seat. At this time, the hanging rod 21 and the guide column 3 are driven upward by the hanging member 4. The hanging rod 21 drives the rotor 20 to rise vertically through the guide column 3. When the lower end of the guide column 3 is higher than the upper end of the stator 10, the hanging member 4 drives the rotor 20 to move to the upper end of the stator 10 through the hanging rod 21, and then the rotor 20 is lowered.

[0049] Reference Figure 2 and Figure 3 When the rotor 20 descends, the guide post 3 first enters the circular hole of the stator 10, passes through the end cover below the stator 10, and finally enters the positioning hole 11. The positioning base 1 limits the guide post 3 through the positioning hole 11, so that the guide post 3 is coaxial with the positioning inner circle, thereby ensuring that the rotor 20 is coaxial with the positioning. When the rotor 20 descends, the upper end mounting hole of the end cover of the upper end of the rotor 20 is directly opposite to the guide rod 121. At this time, the guide rod 121 passes through the mounting hole of the upper end cover of the rotor 20 again, and further guides the rotor 20 through the end cover.

[0050] Reference Figure 1 and Figure 3 When placing the rotor 20, the lateral displacement of the rotor 20 is limited by the action of the suspension rod 21, the guide column 3 and the guide rod 121, and while ensuring that the rotor 20 is coaxial with the stator 10, it is helpful to prevent the magnetic steel on the installation part of the rotor 20 from contacting the inner circle of the stator 10 due to the magnetic attraction, thereby reducing the probability of collision between the magnetic steel and the inner circle of the stator 10, which is beneficial to improve the work efficiency when assembling the stator 10 and the rotor 20.

[0051] Reference Figure 1 and Figure 3 When the end cover on the rotor 20 contacts the upper end surface of the stator 10, the end cover on the rotor 20 is installed on the stator 10 by screws or bolts, thereby completing the assembly of the rotor 20 and the stator 10. When the suspension rod 21 and the rotor 20 move in the horizontal direction, the transport seat 52 moves synchronously in the horizontal direction and finally stops just below the positioning base 1. After the rotor 20 and the stator 10 are assembled, the vertical moving frame 531 drives the disassembly rod 532 and the clamping claw 521 to move upward, and the clamping claw 521 clamps the outer circle of the guide column 3 again, and the disassembly rod 532 extends into the disassembly groove 32, so that the polygonal plate 535 contacts the rotating disk 33. At this time, the rotating member 533 drives the disassembly rod to rotate again, so that the disassembly rod drives the rotating disk 33 to rotate through the polygonal plate 535, thereby removing the threaded rod 331 from the threaded hole 211, and completing the removal of the guide column 3 and the suspension rod 21. After the guide column 3 and the suspension rod 21 are separated, the suspension rod 21 is operated to rise and the vertical displacement seat is lowered. After the suspension rod 21 is moved out from the rotating shaft of the rotor 20, the assembled stator 10 and rotor 20 are moved out, thereby completing the assembly of a set of stators 10 and rotors 20.

[0052] The implementation principle of Example 1 is as follows: the rotor 20 is limited by the cooperation of the suspension rod 21 and the guide column 3, so that the rotor 20 can be moved by the suspension member 4, and the guide column 3 is made coaxial with the rotor 20 by the positioning member 31. When the stator 10 and the rotor 20 are assembled, the positioning base 1 cooperates with the guide column 3 through the positioning hole 11 to guide and limit the rotor 20, so that the rotation axis of the rotor 20 is coaxial with the inner circle of the stator 10, and the displacement of the rotor 20 in the lateral direction is limited, which reduces the probability of the magnetic steel of the rotor 20 installation part contacting the inner circle of the stator 10 when the stator 10 and the rotor 20 are assembled, improves the assembly convenience, and then improves the working efficiency when the rotor 20 and the stator 10 are assembled.

[0053] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the connection method between the guide column 3 and the suspension rod 21 is different, and the clamp 521 does not need to be installed on the transport seat 52. In this embodiment, the diameter of the guide column 3 is not larger than the diameter of the suspension rod 21, and the guide column 3 is coaxially fixed with the suspension rod 21.

[0054] Reference Figure 5 and Figure 6 The positioning member 31 includes a plurality of abutment blocks 311, which are evenly arranged along the circumference of the guide column 3, and all the abutment blocks 311 are slidably connected to the guide column 3 along the radial direction of the guide column 3. The guide column 3 is also provided with a plurality of abutment plates 34 along the circumference, and the abutment plates 34 are located on the side of the abutment blocks 311 away from the suspension rod 21, and all the abutment plates 34 are hinged to the guide column 3 along the axial direction of the guide rod 121.

[0055] Reference Figure 5 and Figure 6 The guide column 3 is provided with a driving member 6 for driving the abutment block 311 and the abutment plate 34 to move. The driving member 6 includes a threaded column, a driving block 1 62 and a driving block 2 63. The guide column 3 is hollow. The driving block 2 63 and the driving block 2 63 are both located in the guide column 3 and are slidably connected with the guide column 3 along the axial direction of the guide column 3, and the driving block 2 63 is located on the side of the driving block 1 62 away from the suspension rod 21. The threaded column includes a mutually coaxial lead screw 1 611 and a lead screw 2 612. The lead screw 1 611 and the lead screw 2 612 are both located in the guide column 3 and are rotatably connected with the guide column 3. When the lead screw 1 611 rotates, the lead screw 2 612 is driven to rotate. The lead screw 2 612 is located at one end of the lead screw 1 611 away from the suspension rod 21, and the lead screw 2 612 passes through the guide column 3 and is fixedly connected with a disassembly head. The disassembly head is adapted to the disassembly mechanism. When the stator 10 and the rotor 20 are assembled, the disassembly head is driven to rotate through the disassembly structure. In the initial state, all the abutment blocks 311 and the abutment plates 34 are located close to the axis of the guide column 3. When assembling the suspension rod 21 and the rotor 20, all the abutment blocks 311 are located in the inner hole of the rotor 20 shaft, and all the abutment plates 34 are located below the rotor 20 shaft.

[0056] Reference Figure 5 and Figure 6 The lead screw 1 611 passes through the driving block 1 62 and is threadedly connected to the driving block 1 62. When the lead screw 1 611 rotates, it pushes the driving block 1 62 to move along the axial direction of the guide column 3. The lead screw 2 612 passes through the driving block 2 63 and is threadedly connected to the driving block 2 63. When the lead screw 2 612 rotates, it drives the driving block 2 63 to move. The lead screw 1 611 and the lead screw 2 612 have different pitches, so when the disassembly head rotates the same angle, the moving distances of the driving block 1 62 and the driving block 2 63 are different.

[0057] Reference Figure 5 and Figure 6All the abutment blocks 311 are vertically hinged with a push rod 312. One end of the push rod 312 away from the abutment block 311 is vertically hinged with a driving block 62. When the driving block 62 moves, the push rod 312 drives the abutment block 311 to approach the inner wall of the rotor 20 shaft. When the abutment block 311 contacts the inner wall of the rotor 20 shaft, the guide column 3 is connected to the suspension rod 21, and the guide column 3 is coaxial with the suspension rod 21. All the abutment plates 34 are vertically hinged with a push rod 2 341, and the push rod 2 341 is vertically hinged to the driving block 2 63. When the driving block 2 63 moves, the push rod 2 341 drives the abutment plate 34 to rotate, and then the abutment plate 34 flips vertically. When the abutment plate 34 contacts the lower end surface of the rotor 20 shaft, the hanging plate 22 cooperates with the abutment plate 34 to clamp the rotor 20 shaft vertically, so as to facilitate the movement of the rotor 20 shaft through the hanging component 4.

[0058] Reference Figure 5 and Figure 6 The upper end of the positioning base 1 is provided with an annular groove 111 connected with the positioning hole 11. When the guide column 3 enters the positioning hole 11, all the abutment plates 34 are located in the annular groove 111. When the positioning base 1 limits the guide column 3 through the positioning hole 11, the abutment plates 34 are avoided by the annular groove 111. In the process of assembling the stator 10 and the rotor 20, there is no need to repeatedly disassemble the guide column 3, and the guide column 3 and the rotor 20 shaft are kept coaxial by moving the abutment block 311, which is conducive to further improving the convenience of assembling the stator 10 and the rotor 20.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
