Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet motor installation, specifically to a permanent magnet motor assembling machine and an assembling method. Background Technique

[0002] A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field, and has the characteristics of simple structure, high reliability, and high efficiency. A permanent magnet motor usually consists of a stator, a rotor, and a control device.

[0003] When installing the stator and rotor inside a permanent magnet motor, machines are usually needed for installation. However, the existing permanent magnet motor assembling machines lack a limiting mechanism when installing the stator and rotor. During the installation process, if the stator and rotor are not coaxial and the clearance between them is small, the rotor will encounter a large resistance during installation. If the installation mechanism is not limited and the installation continues regardless of the installation resistance, the rotor and stator will adsorb to each other, causing damage to the stator and affecting the assembling effect. Moreover, after the stator and rotor are installed, the rotor is usually rotated for testing to see if it is coaxial with the stator. If there is a slight deviation between the axes of the two, the rotor will vibrate during rotation and generate friction with the components around the stator, such as bearings and sealing rings, thus generating heat on the surface of the rotor. When the rotor is pulled out and reinstalled, if the rotor is not cooled down, it may cause thermal deformation of the rotor and affect the installation effect. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: Please refer to Figure 1 - Figure 9 , a permanent magnet motor assembling machine, including an equipment main body 1, an inner groove 10 is arranged on the equipment main body 1, an installation table 2 is installed inside the inner groove 10, an outer shell 3 is installed on the installation table 2, a stator 4 is installed inside the outer shell 3, a forward and reverse motor 51 is fixedly connected to the side wall of the equipment main body 1, a threaded rod 9 is arranged at the output end of the forward and reverse motor 51, the threaded rod 9 slides through to the inside of the inner groove 10, a pushing table 5 is threadedly sleeved on the outside of the threaded rod 9, a jacking rod 7 is slidably arranged inside the pushing table 5, a mechanical claw is arranged at one end of the jacking rod 7 away from the pushing table 5, a rotor 8 is arranged on the mechanical claw, and an elastic assembling mechanism is arranged inside the jacking rod 7; the elastic assembling mechanism includes swing arms 13 rotatably connected to both sides of the end of the jacking rod 7, slide rails 12 are arranged on both sides inside the pushing table 5, a pushing member 16 is slidably connected to the inner side wall of the slide rail 12, and one end of the swing arm 13 away from the jacking rod 7 is rotatably connected to the outer side wall of the pushing member 16.

[0034] A push rod 17 is fixedly connected to the outer side wall of the driving member 16. The push rod 17 slidably penetrates to the outside of the push table 5. A compression spring 15 is sleeved on the outer side wall of the push rod 17. One end of the push rod 17 away from the driving member 16 is fixedly connected to a friction contact plate 14. A pressure sensor is arranged inside the friction contact plate 14. A compression spring 11 is sleeved on the end of the ejector rod 7 located inside the push table 5.

[0035] Side rods 6 are fixedly connected to both sides of the equipment main body 1. A plurality of card slots 50 are arranged at the front end of the side rod 6. A cold air box 49 is arranged on the outer side wall of the side rod 6. A rotor processing mechanism is arranged on the outer side wall of the side rod 6. The rotor processing mechanism includes an outer ring 18 arranged between the two side rods 6. Fixed rods 19 are fixedly connected to both sides of the outer ring 18. The ends of the fixed rods 19 are fixedly connected to the side rods 6. A plurality of sector plates 20 are slidably connected inside the outer ring 18. Cleaning brushes 48 are arranged on the outer side walls of the plurality of sector plates 20.

[0036] In this actual example, when in use, first, the rotor 8 to be installed can be placed on the mechanical claw and fixed by the mechanical claw. After the position of the rotor 8 is fixed, the housing 3 to be assembled can be placed on the installation table 2 to align the axis of the stator 4 and the rotor 8. When the positions of the stator 4 and the rotor 8 are fixed, at this time, the operator can turn on the forward and reverse motor 51 to drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it will push the ejector rod 7 and the rotor 8 to move towards the housing 3 through the push table 5. During the process of the ejector rod 7 pushing the rotor 8 into the housing 3, the rotor 8 will pass through the outer ring 18. During the process of the rotor 8 passing through the outer ring 18, the cleaning brush 48 will scrape the surface of the rotor 8 in contact with it to scrape and clean impurities such as dust and dirt on the surface of the rotor 8. After the rotor 8 passes through the outer ring 18, it will enter the housing 3 to assemble the rotor 8 and the stator 4. When the rotor 8 and the stator 4 are assembled, if the fitting gaps between them are relatively average at this time, the attractive magnetic force of the stator 4 on the ejector rod 7 is relatively small. At this time, the pushing resistance of the rotor 8 is also relatively small. Under the relatively small resistance, the ejector rod 7 will smoothly push the rotor 8 into the stator 4 for assembly.

[0037] Example two: Please refer to Figure 1 - Figure 9 A pressure rod 22 is fixedly connected to the outer side wall of each of the plurality of sector plates 20. The pressure rod 22 penetrates to the outside of the outer ring 18. A return spring 25 is sleeved on one end of the pressure rod 22 located outside the outer ring 18. A convex block 23 is fixedly connected to the end of the pressure rod 22 away from the sector plate 20.

[0038] On both sides of the outer side wall of the outer ring 18, limit rods 33 are fixedly connected. A back ring 21 is slidably connected to the outside of the two limit rods 33 on both sides. An adsorption magnet 38 is arranged at the bottom of the back ring 21. A tension spring 29 is arranged on the outer side wall of the back ring 21. A plurality of pressing plates 24 are fixedly connected to the outer side wall of the back ring 21. One end of the plurality of pressing plates 24 away from the back ring 21 is in sliding contact with the convex block 23.

[0039] An airbag 37 is installed on the outer ring 18. A pressure plate 27 is in contact with the outside of the airbag 37. A return spring 28 is fixedly connected to the outer side wall of the pressure plate 27. The other end of the return spring 28 is connected to the outer ring 18. A trigger magnet 32 is fixedly connected to the outer side wall of the pressure plate 27. A jet pipe 34 and a suction pipe 26 are communicated inside the airbag 37. One end of the suction pipe 26 away from the airbag 37 is communicated to the inside of the cold air box 49. An air ring 35 is arranged outside the back ring 21. A plurality of jet holes 36 are opened inside the air ring 35. One end of the jet pipe 34 away from the airbag 37 is communicated to the inside of the air ring 35.

[0040] The end of the threaded rod 9 is connected to a driving rod 30 through a jaw disc. A belt 31 is sleeved on the outer side wall of the driving rod 30. A driven rod 40 is rotatably connected to the outer side wall of the outer ring 18. The other end of the belt 31 is sleeved on the outer side wall of the driven rod 40. A connecting wheel 44 is arranged at the end of the driven rod 40. A plurality of baffles 46 are rotatably connected inside the connecting wheel 44. A plurality of pressing springs 47 are respectively fixedly connected to the outer side walls of the plurality of baffles 46. One end of the pressing spring 47 away from the baffle 46 is fixedly connected to the inner side wall of the connecting wheel 44. A one-way tooth disc 45 is sleeved on the outside of the driven rod 40. The one-way tooth disc 45 is in sliding connection with the baffle 46. A runner 39 is arranged outside the connecting wheel 44. A plurality of sliding frames 41 are arranged on the runner 39. A sliding rod is fixedly connected inside each of the plurality of sliding frames 41. A pressing magnet 42 is slidably connected to the outer side wall of the sliding rod. The magnetic pole of the pressing magnet 42 is opposite to that of the adsorption magnet 38 and the same as that of the trigger magnet 32. A sleeve spring 43 is arranged on the outer side wall of the sliding rod.

[0041] In this embodiment, on the contrary, during the installation process, due to dimensional deviations of components or other circumstances, if the rotor 8 and the stator 4 are not coaxial, when the ejector rod 7 pushes the rotor 8 into the stator 4, the clearance between them will be uneven at this time, resulting in larger and smaller clearances. At this time, under the suction force of the stator 4, the pushing resistance of the rotor 8 will increase. In the case of a large pushing resistance, the pressing spring 11 will contract over a large distance. While the pressing spring 11 contracts over a large distance, the swing arm 13 will also deflect to both sides of the slide rail 12, and the push rod 17 will be pushed to move towards both sides of the push table 5 through the pusher 16. When the push rod 17 moves towards both sides of the push table 5, it will push the friction contact plate 14 into the card slot 50 inside the side rod 6, thereby fixing and limiting the position of the push table 5, preventing the push table 5 from continuing to push, and avoiding the ejector rod 7 from continuing to push, which may cause the deviation between the rotor 8 and the stator 4 to become larger and larger until the rotor 8 and the stator 4 are adsorbed to each other. When the friction contact plate 14 is inserted into the card slot 50, the pressing sensor inside the friction contact plate 14 will also be triggered, causing the forward and reverse motor 51 to stop rotating. After the forward and reverse motor 51 stops rotating, at this time, the operator can reverse the threaded rod 9 through the forward and reverse motor 51 to move the push table 5 back to the outside of the equipment main body 1 and extract the rotor 8 from the stator 4.

[0042] After installation is completed under a relatively small resistance and during testing, there are still two situations. The first one is that after the rotor 8 is completely installed in the stator 4, at this time, the operator can drive the mechanical claw to drive the rotor 8 to rotate inside the stator 4 (this is prior art and will not be elaborated too much). When the rotor 8 rotates inside the stator 4, if the rotation state of the rotor 8 is normal, it means that the rotor 8 and the stator 4 are in a completely coaxial state. At this time, the mechanical claw can be released to let the rotor 8 stay in the stator 4 for the next assembly step.

[0043] Second type: If there is still slight jitter when the rotor 8 is rotating, it means that there is still a very slight deviation between the axes of the rotor 8 and the stator 4 at this time. This very slight deviation will cause friction between the rotor 8 and the components around the stator 4, such as bearings and sealing rings, when the rotor 8 rotates inside the stator 4, generating heat on the surface of the rotor 8. After the slight deviation exists, the operator can reverse the threaded rod 9 by rotating the forward and reverse motor 51 at this time. When the threaded rod 9 rotates in reverse, it will cause the push table 5 to move outward again towards the outside of the equipment main body 1, pulling out the rotor 8 from the stator 4. When the rotor 8 rotates in reverse, it will also drive the drive rod 30 to rotate in reverse through the jaw clutch. When the drive rod 30 rotates in reverse, it will drive the driven rod 40 and the one-way tooth disc 45 at its end to rotate synchronously through the action of the belt 31. When the one-way tooth disc 45 rotates in reverse, the baffle 46 will press against the right-angle side of the one-way tooth disc 45 at this time, thereby driving the runner 39 to rotate synchronously. When the runner 39 rotates, under the action of centrifugal force, the pressing magnet 42 will be thrown to the outside of the sliding frame 41 against the elastic force of the socket spring 43. When the pressing magnet 42 located outside the sliding frame 41 just lies on the front side of the adsorption magnet 38, at this time, under the action of the attracting magnetic force, the back ring 21 will move towards the direction close to the runner 39 against the pulling force of the tension spring 29. Correspondingly, the multiple pressing plates 24 connected to the back ring 21 will also move with the back ring 21, disengaging from the contact with the convex blocks 23. At this time, without the pressing of the pressing plates 24, under the elastic force of the return spring 25, the sector plate 20 will drive the cleaning brush 48 to contract into the outer ring 18. When the pressing magnet 42 located outside the sliding frame 41 rotates, it will intermittently lie on the front side of the trigger magnet 32. Under the action of the intermittent magnetic force and the elastic force of the return spring 28, the pressure plate 27 will press the airbag 37 reciprocally. When the airbag 37 is pressed reciprocally, it will first suck the cold air processed in the cold air box 49 into its interior through the suction pipe 26, and then spray it through the multiple air spray holes 36. When the cold air is sprayed from the air spray holes 36, when the ejector rod 7 drives the rotor 8 to move back and pass through the outer ring 18 again, the cold air sprayed by the outer ring 18 will cool down the high temperature on the surface of the rotor 8, preventing the rotor 8 from undergoing thermal deformation due to excessive temperature.

[0044] The assembling method of a permanent magnet motor assembling machine, the method comprising the following steps;

[0045] S1: When in use, first, the rotor 8 to be installed can be placed on the mechanical claw and fixed by the mechanical claw. After the position of the rotor 8 is fixed, the housing 3 to be assembled can be placed on the installation table 2 to align the axes of the stator 4 and the rotor 8;

[0046] S2: When the positions of the stator 4 and the rotor 8 are fixed, the operator can turn on the forward and reverse motor 51 at this time to drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it will push the ejector rod 7 and the rotor 8 towards the direction of the housing 3 through the push table 5 for installation.

[0047] S3: During the installation process, the elastic assembling mechanism will conduct an assembling determination in advance. If the resistance is small, normal assembling can be carried out.

[0048] S4: If the elastic assembling mechanism senses a large resistance, the entire ejector rod 7 will stop assembling at this time.

[0049] It should be noted that when the rotor 8 and the stator 4 are aligned axially in advance and a small deflection occurs, the deflection angle is usually small at this time and will not adsorb and contact the inner wall of the stator 4 when the rotor 8 is just inserted into the stator 4. In the technical solution of the present invention, when the rotor 8 is inserted with a large resistance, it is in a state where the rotor 8 and the stator 4 are not adsorbed, and there is still a gap between the two. When the axis deflects and there is still a gap between the rotor 8 and the stator 4, the insertion of the rotor 8 can be locked to avoid the stator 4 and the rotor 8 from adsorbing to each other. When a large deflection occurs during the insertion process and the stator 4 and the rotor 8 adsorb, professional equipment needs to be used for removal at this time. This is the prior art and will not be elaborated too much.

[0050] It should also be noted that check valves are provided inside both the suction pipe 26 and the airbag 37, which can ensure that the suction pipe 26 only sucks air and the air jet pipe 34 only jets air.

[0051] It should also be noted that when the runner 39 drives the pressing magnet 42 to rotate, the adsorption magnet 38 will always be in an adsorbed state at this time, because Figure 7 seen from the perspective, the adsorption magnet 38 is larger in size and covers the two sliding frames 41. Therefore, when the runner 39 drives the sliding frame 41 to rotate, there will always be a pressing magnet 42 on the side of the adsorption magnet 38. Therefore, when the high-temperature rotor 8 is pulled out, affected by the magnetic force, the cleaning brush 48 is always stored in the outer ring 18 to avoid the cleaning brush 48 contacting the high-temperature outer ring 18 and causing damage to the cleaning brush 48.

[0052] It should be noted that referring to Figure 9 , in the technical solution of the present invention, the forward rotation of the one-way gear disk 45 is counterclockwise rotation, and the reverse rotation is clockwise rotation.

[0053] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0054] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
