Description

Technical Field

[0001] This utility model relates to the field of motor disassembly technology, and in particular to a motor disassembly device with real-time displacement monitoring function. Background Technology

[0002] When disassembling a motor rotor, in order to minimize damage to the motor rotor and stator, a motor disassembly device is generally used for auxiliary disassembly.

[0003] A search revealed a patent document with publication number "CN201994789U" disclosing a horizontal assembly and disassembly device for a permanent magnet synchronous motor stator and rotor. The device includes a base with rotor fixing platforms at both ends. One platform is a first rotor fixing platform with a fixing pin mounted on it; the other is a second rotor fixing platform with another long pin mounted on it. The long pin passes through the inner hole of the stator, and the rotor is clamped and fixed by the two pins. A moving guide rail is located in the middle of the base, and the stator fixing platform is mounted on the moving guide rail and can move along it. A stator positioning plate is mounted on the surface of the stator fixing platform, and a floating auxiliary platform is located between the stator and the platform. A screw-type moving mechanism is mounted under the stator fixing platform. The nut of the screw-type moving mechanism is mounted on the stator fixing platform, and the screw of the screw-type moving mechanism is mounted on the base, with one end connected to a drive motor.

[0004] Based on the above research and existing technology, it was found that the height of the ejector pin and positioning plate in existing motor disassembly devices is fixed. During the motor disassembly process, the outer wall of the rotor must not collide or scratch with the inner wall of the stator. It is necessary to ensure that the center line of the rotor, the center line of the stator, and the coaxial lines of the ejector pins on both sides of the disassembly device are aligned. This means that the motor must first be adjusted in height to ensure that the motor shaft is aligned with the axis of the ejector pin and positioning plate before disassembly can proceed. However, it is not easy to calibrate by adjusting the height, which can easily lead to certain deviations during disassembly, resulting in damage to the motor rotor or stator. Therefore, a motor disassembly device with real-time displacement monitoring function is needed. Utility Model Content

[0005] The purpose of this application is to provide a motor disassembly device with real-time displacement monitoring function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a motor disassembly device with real-time displacement monitoring function, including a base, a stator fixing platform fixed above the base, a sliding groove on the upper surface of the base, a sliding block slidably embedded in the sliding groove, and a drive mechanism for driving the sliding block to slide on the base.

[0007] Two retractable support columns are fixed at both ends of the slide and are symmetrically distributed along the middle of the slide. Both support columns extend vertically. Electric push rods are fixed at the upper ends of the telescopic columns of the two support columns. The two electric push rods are mirror images of each other and extend horizontally. The piston rod ends of the two electric push rods are close to each other and are fixed with top shafts.

[0008] An auxiliary calibration component is installed on one side of the stator fixing platform. The auxiliary calibration component can be lifted and installed on the stator fixing platform, and it can also slide horizontally along the stator fixing platform. The auxiliary calibration component is connected to the telescopic column through a linkage rod group, and the auxiliary calibration component and the telescopic column are raised and lowered synchronously.

[0009] A rotor support with its lower end fixed to the base is provided on one side of the stator fixing platform. Displacement sensors are fixed on the upper part of the stator fixing platform away from the rotor support and on the upper part of the rotor support near the stator fixing platform. The displacement sensors are electrically connected to the drive mechanism and the electric push rod.

[0010] Preferably, the auxiliary calibration assembly is located on the side of the stator fixing platform away from the rotor support, and the auxiliary calibration assembly includes a calibration block, a sliding block, and a lifting rod;

[0011] The calibration block has a calibration cone hole. The inner diameter of the calibration cone hole at the end near the rotor support is larger than the inner diameter of the end away from the rotor support. The sliding block is horizontally slidably installed on the stator fixing platform. The upper end of the lifting rod is fixed to the lower end of the calibration block. The lower end of the lifting rod slides through the sliding block and forms a connecting block fixed to the end of the linkage group. The lifting rod slides vertically.

[0012] Preferably, the linkage assembly includes a telescopic rod and a follower rod. One end of the telescopic rod is fixed to one of the telescopic columns, and the other end of the telescopic rod is fixed to a connecting block. The telescopic rod is located on the side of the stator fixing platform near the rotor support. One end of the follower rod is fixed to the side of the connecting block away from the telescopic rod, and the other end of the follower rod slides through another telescopic column.

[0013] Preferably, the stator fixing platform is provided with mounting holes and sliding holes, and the sliding block is slidably embedded in the sliding holes.

[0014] Preferably, a groove is also provided on the stator fixing platform, and a sliding bolt is slidably embedded in the groove;

[0015] The sliding block has a connecting hole for the sliding bolt to pass through, and a locking nut is screwed onto the sliding bolt. The lower end of the locking nut abuts against the upper surface of the sliding block.

[0016] Preferably, a flexible support is fixed to the upper end of the rotor support, and two flexible supports are provided for both the rotor support and the flexible support, which are located on the front and rear sides of the support column respectively.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. In this utility model, by setting up auxiliary calibration components and linkage rod groups, the purpose of aligning the top shaft with the motor rotor axis is achieved. Then, the electric push rod is activated to make the two top shafts clamp the two ends of the motor rotor shaft respectively. Then, the drive mechanism drives the slide to move to one side of the rotor support, so that the motor rotor moves accordingly. When the motor rotor moves to the rotor support, the electric push rod is activated again and the two top shafts are separated from the motor rotor shaft, thereby completing the disassembly of the motor rotor.

[0019] During operation, the displacement sensor can detect the displacement of the motor rotor in real time and control the drive mechanism to stop moving when the motor rotor deviates, thereby avoiding further damage to the motor rotor or stator during disassembly. The calibration function of the auxiliary calibration component enables the motor disassembly device to be used for disassembling motors of different sizes, thereby improving the flexibility of the motor disassembly device and making it more effective.

[0020] 2. In this utility model, by setting up an auxiliary calibration component, the calibration block only needs to be manually lifted so that it is fastened to the end of the motor rotor shaft and the end of the shaft is located in the calibration cone hole. Then, the calibration block is pressed against the shaft, so that the calibration block and the shaft are coaxial. During the lifting and lowering process of the calibration block, the calibration block drives the telescopic rod and the follower rod to lift and lower synchronously through the lifting rod, thereby driving the two telescopic columns to lift and lower synchronously, thus achieving the purpose of driving the two electric push rods to lift and lower synchronously. Finally, the adjusted top shaft and the rotor shaft are coaxial, which is suitable for the alignment of the rotor shaft of different models of motors. Attached Figure Description

[0028] 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.

[0029] Example: Reference Figures 1-5 The motor disassembly device shown includes a base 1 and a stator fixing platform 4 fixed above the base 1. A sliding groove 11 is provided on the upper surface of the base 1, and a slide block 12 is slidably embedded in the sliding groove 11. A drive mechanism 2 for driving the slide block 12 to slide is also installed on the base 1. The drive mechanism 2 consists of a motor and a drive screw. The drive screw passes through the slide block 12 and is adapted to it. After the motor is started, it drives the drive screw to rotate.

[0030] Two retractable support columns 3 are fixed at both ends of the slide block 12 and are symmetrically distributed along the middle of the slide block 12. Both support columns 3 extend vertically. Electric push rods 6 are fixed at the upper ends of the telescopic columns 31 of the two support columns 3. The two electric push rods 6 are mirror images and extend horizontally. The piston rod ends of the two electric push rods 6 are close to each other and are fixed with top shafts 61.

[0031] An auxiliary calibration component 5 is installed on one side of the stator fixing platform 4. The auxiliary calibration component 5 can be lifted and installed on the stator fixing platform 4, and the auxiliary calibration component 5 can also slide horizontally along the stator fixing platform 4. The auxiliary calibration component 5 is connected to the telescopic column 31 through the linkage rod group 9, and the auxiliary calibration component 5 and the telescopic column 31 are lifted and lowered synchronously.

[0032] A rotor support 7 with its lower end fixed to the base 1 is provided on one side of the stator fixing platform 4. Displacement sensors 8 are fixed on the upper part of the stator fixing platform 4 away from the rotor support 7 and on the upper part of the rotor support 7 near the stator fixing platform 4. The displacement sensors 8 are electrically connected to the drive mechanism 2 and the electric push rod 6.

[0033] Based on the above structure, the motor is first fixed to the stator mounting platform 4 with bolts. Then, the auxiliary calibration component 5 is moved so that it fits against the tail end cover of the motor rotor and coincides with the rotor axis of the motor. During this process, the auxiliary calibration component 5 drives the telescopic column 31 to rise and fall synchronously through the linkage rod group 9, thereby causing the electric push rod 6 and the top shaft 61 to rise and fall synchronously, so that the top shaft 61 coincides with the rotor axis of the motor. Then, the electric push rod 6 is activated so that the two top shafts 61 clamp the two ends of the motor rotor shaft respectively. Then, the drive mechanism 2 drives the slide 12 to move to one side of the rotor bracket 7, so that the motor rotor moves accordingly. When the motor rotor moves to the rotor bracket 7, the electric push rod 6 is activated again and the two top shafts 61 are separated from the rotor shaft of the motor, thus completing the disassembly of the motor rotor.

[0034] During operation, the displacement sensor 8 can detect the displacement of the motor rotor in real time, and control the drive mechanism 2 to stop moving when the motor rotor deviates, thereby avoiding further damage to the motor rotor or stator during disassembly. The calibration function of the auxiliary calibration component 5 enables the motor disassembly device to be used for disassembling motors of different sizes, thereby improving the flexibility of the motor disassembly device and making it more effective.

[0035] Furthermore, the auxiliary calibration component 5 is located on the side of the stator fixing platform 4 away from the rotor support 7, and the auxiliary calibration component 5 includes a calibration block 51, a sliding block 52 and a lifting rod 53;

[0036] The calibration block 51 has a calibration cone hole 511. The inner diameter of the calibration cone hole 511 near the rotor support 7 is larger than the inner diameter of the calibration cone hole 511 away from the rotor support 7. The sliding block 52 is horizontally slidably installed on the stator fixing platform 4. The upper end of the lifting rod 53 is fixed to the lower end of the calibration block 51. The lower end of the lifting rod 53 slides through the sliding block 52 and forms a connecting block 531 fixed to the end of the linkage rod group 9. The lifting rod 53 slides vertically.

[0037] Furthermore, the linkage assembly 9 includes a telescopic rod 91 and a follower rod 92. One end of the telescopic rod 91 is fixed to one of the telescopic columns 31, and the other end of the telescopic rod 91 is fixed to the connecting block 531. The telescopic rod 91 is located on the side of the stator fixing platform 4 near the rotor support 7. One end of the follower rod 92 is fixed to the side of the connecting block 531 away from the telescopic rod 91, and the other end of the follower rod 92 slides through another telescopic column 31.

[0038] After fixing the motor, the operator only needs to manually lift the calibration block 51 so that the calibration block 51 is engaged with the end of the motor rotor shaft and the end of the shaft is located in the calibration cone hole 511. Then, the calibration block 51 is pressed against the shaft to make the calibration block 51 coaxial with the shaft. During the lifting and lowering process of the calibration block 51, the calibration block 51 drives the telescopic rod 91 and the follower rod 92 to lift and lower synchronously through the lifting rod 53, thereby driving the two telescopic columns 31 to lift and lower synchronously. This achieves the purpose of driving the two electric push rods 6 to lift and lower synchronously, and finally makes the adjusted top shaft 61 coaxial with the rotor shaft, which is suitable for the alignment of the rotor shaft of different models of motors.

[0039] Furthermore, the stator fixing platform 4 is provided with mounting waist hole 41 and sliding hole 42, the sliding block 52 is slidably embedded in the sliding hole 42, and the stator fixing platform 4 is also provided with groove 43, in which sliding bolt 54 is slidably embedded.

[0040] The sliding block 52 has a connecting hole 521 for the sliding bolt 54 to pass through. A locking nut 55 is screwed onto the sliding bolt 54, and the lower end of the locking nut 55 abuts against the upper surface of the sliding block 52.

[0041] Before calibration, the operator needs to loosen the locking nut 55 so that the sliding bolt 54 can slide with the sliding block 52. After calibration, the operator only needs to tighten the locking nut 55 so that the lower end of the locking nut 55 abuts against the upper surface of the sliding block 52, which can limit the sliding block 52 and fix the horizontal position of the calibration block 51. Since the calibration cone hole 511 of the calibration block 51 abuts against the end of the rotor shaft at this time, the height of the calibration block 51 is limited, thereby fixing the position of the lifting rod 53.

[0042] Furthermore, a flexible support platform 71 is fixed to the upper end of the rotor bracket 7. Two rotor brackets 7 and two flexible support platforms 71 are provided and located on the front and rear sides of the support column 3 respectively. The flexible support platform 71 can provide flexible support for the disassembled electronic rotor, thereby protecting the disassembled motor rotor and keeping the motor rotor intact after disassembly.

[0043] The working principle of this utility model is as follows: In daily use, the motor is first fixed to the stator fixing platform 4 with bolts. Then, the operator needs to loosen the locking nut 55 so that the sliding bolt 54 can slide with the sliding block 52. At this time, the calibration block 51 is manually lifted so that the calibration block 51 is engaged with the end of the motor rotor shaft and the end of the shaft is located in the calibration cone hole 511. Then, the calibration block 51 is pressed against the shaft so that the calibration block 51 and the shaft are coaxial. The operator only needs to tighten the locking nut 55 so that the lower end of the locking nut 55 is pressed against the upper surface of the sliding block 52, which limits the sliding block 52 and fixes the horizontal position of the calibration block 51. Since the calibration cone hole 511 of the calibration block 51 is pressed against the end of the rotor shaft, the height of the calibration block 51 is limited, thereby fixing the position of the lifting rod 53.

[0044] During the lifting and lowering process of calibration block 51, calibration block 51 drives telescopic rod 91 and follower rod 92 to lift and lower synchronously through lifting rod 53, thereby driving two telescopic columns 31 to lift and lower synchronously, thus achieving the purpose of driving two electric push rods 6 to lift and lower synchronously. Finally, the adjusted top shaft 61 and the rotor shaft are made coaxial, which can adapt to the alignment operation of the rotor shaft of different models of motors. Then, the electric push rod 6 is started so that the two top shafts 61 clamp the two ends of the rotor shaft of the motor respectively. Then, the drive mechanism 2 drives the slide 12 to move to one side of the rotor support 7, so that the motor rotor moves accordingly. When the motor rotor moves to the rotor support 7, the electric push rod 6 is started again and the two top shafts 61 are separated from the rotor shaft of the motor, thus completing the disassembly operation of the motor rotor.

[0045] During operation, the displacement sensor 8 can detect the displacement of the motor rotor in real time, and control the drive mechanism 2 to stop moving when the motor rotor deviates, thereby avoiding further damage to the motor rotor or stator during disassembly. The calibration function of the auxiliary calibration component 5 enables the motor disassembly device to be used for disassembling motors of different sizes, thereby improving the flexibility of the motor disassembly device and making it more effective.

[0046] It should be further noted that the technical features such as the drive mechanism, electric push rod, displacement sensor, and telescopic rod involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
