Description

Technical Field

[0001] This invention relates to the field of motor maintenance technology, and in particular to a maintenance device for permanent magnet motors that is easy to maintain. Background Technology

[0002] Permanent magnet motors are widely used in industrial drives, new energy vehicles, and rail transportation due to their high efficiency and power density. As the core rotating component of a permanent magnet motor, the bearing's operating condition directly affects the motor's stability and lifespan. After long-term operation, bearings are prone to eccentricity due to wear, installation misalignment, etc. If not inspected and repaired in time, this may lead to increased motor vibration, increased noise, or even shutdown, increasing maintenance costs.

[0003] Current methods for inspecting permanent magnet motor bearings often rely on manual visual inspection or simple tool measurements. This approach has several drawbacks: low inspection accuracy (manual observation makes it difficult to quantify the degree of eccentricity and relies on experience, which can easily lead to misjudgments); cumbersome operation (if the bearing needs to be disassembled after inspection, additional tools such as pullers are required, making the process complex and potentially damaging the motor shaft or bearing due to improper operation); and efficiency needs further improvement (the inspection and disassembly processes are separate, requiring multiple adjustments to the motor position, which is time-consuming). Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art by providing a maintenance device for a permanent magnet motor that is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A maintenance-friendly permanent magnet motor repair device includes a repair platform fixedly connected to a bracket, a mounting plate for mounting the motor fixedly connected to the repair platform, and further includes: The slide plate is slidably connected to a groove opened in the inspection table; A support plate is rotatably connected to a slide plate. A camera is fixedly connected to one side of the support plate, and a detection sleeve is rotatably connected to the other side of the support plate. The detection sleeve is a double-layered sleeve; Multiple sets of first detection bladders are fixedly connected to the outer shell of the detection sleeve, and a first pressure sensor is fixedly connected to each of the first detection bladders. Multiple sets of second detection bladders are fixedly connected to the inner shell of the detection sleeve, and a second pressure sensor is fixedly connected to each of the second detection bladders. The motor is fixedly mounted on the mounting plate. After removing the protective shell, the bearing inside the motor is exposed. The camera is aimed at and photographed, and the photographed information is uploaded to the computer platform. The computer platform analyzes and compares the bearing eccentricity distance. The support plate rotates 180° so that the detection sleeve faces the motor. The slide plate slides so that the detection sleeve wraps around the bearing. The first and second detection bladders are inflated. The detection sleeve rotates 360°. Each set of first and second pressure sensors uploads pressure signals to the computer platform in real time. The computer platform then analyzes and compares the bearing's eccentricity distance and eccentricity position.

[0006] Preferably, a drive cylinder is fixedly connected to the detection sleeve, a slide plug is slidably connected to the drive cylinder, an elastic pull rod is fixedly connected to the slide plug, and a guide plate is rotatably connected to the detection sleeve via a rotating shaft. When the slide plug drives the elastic pull rod to move, the guide plate squeezes and limits the elastic pull rod, causing the elastic pull rod to deform and tilt upwards. The top of the tilted elastic pull rod extends into and hooks the bearing.

[0007] Furthermore, the detection sleeve has a first connecting cavity and a second connecting cavity, and a first connecting pipe and a second connecting pipe are fixedly connected to the detection sleeve. One end of the first connecting pipe is connected to the first connecting cavity, and the other end of the first connecting pipe is connected to the first detection capsule. One end of the second connecting pipe is connected to the second connecting cavity, and the other end of the second connecting pipe is connected to the second detection capsule.

[0008] Furthermore, the detection sleeve has an air supply chamber, and a first air supply pipe, a second air supply pipe, and a third air supply pipe are fixedly connected to the detection sleeve. The first air supply pipe, the second air supply pipe, and the third air supply pipe are all connected to the air supply chamber. The first air supply pipe is connected to the second connecting cavity, the second air supply pipe is connected to the drive cylinder, and the third air supply pipe is connected to the first connecting cavity.

[0009] Furthermore, the support plate has an air storage chamber, and a sealing tube is rotatably connected to the support plate. The sealing tube is fixedly connected to the detection sleeve, and the sealing tube connects the air storage chamber and the air delivery chamber.

[0010] Furthermore, a filling bladder is fixedly connected to the detection sleeve, and an air supply pipe is fixedly connected to the second detection bladder. The air supply pipe is connected to the filling bladder. When the second detection bladder deflates, the filling bladder bulges and pushes up the guide plate.

[0011] Furthermore, an iron ring is fixedly connected to the slide plug, and an electromagnet is fixedly connected to the drive cylinder, with the iron ring attracting the electromagnet.

[0012] Furthermore, a tension spring is fixedly connected to the slide, and the end of the tension spring away from the slide is fixedly connected to the inner wall of the drive cylinder.

[0013] Furthermore, a first driving unit is fixedly connected to the support plate, a first gear is fixedly connected to the driving end of the first driving unit, and a second gear is fixedly connected to the detection sleeve, wherein the first gear meshes with the second gear.

[0014] Furthermore, both the first and second detection capsules are elastic wear-resistant capsules.

[0015] Compared with the prior art, the present invention provides a maintenance device and switching control method for a permanent magnet motor that is easy to maintain, and has the following beneficial effects: This invention uses an image analyzer to make a preliminary judgment on bearing eccentricity. When the multiple sets of first and second detection chambers of the detection sleeve rotate 360° with the sleeve, pressure signals are collected in real time by pressure sensors. The computer platform combines multiple sets of data for comparison to accurately quantify the eccentricity distance and position, avoid human misjudgment, and effectively improve the detection accuracy.

[0016] This invention enables rapid switching between shooting detection and sleeve detection and disassembly modes by rotating the support plate, eliminating the need for repeated adjustments to the motor position. When severe bearing eccentricity is detected, the drive cylinder drives the elastic pull rod to hook the bearing, and the slide plate resets to complete the disassembly, saving additional tools, simplifying the operation process, and improving maintenance efficiency.

[0017] In this invention, the detection data is uploaded to a computer platform in real time, and automated analysis replaces manual judgment, reducing interference from human factors. All actions are automatically executed by electric push rods, drive units, etc., reducing the difficulty of operation and making it suitable for batch motor maintenance scenarios, further improving maintenance efficiency and accuracy.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: Refer to Figures 1-15 A maintenance device for a permanent magnet motor, which is easy to maintain, includes a maintenance platform 101 fixedly connected to a bracket 1, a mounting plate 1011 for mounting a motor 2 fixedly connected to the maintenance platform 101, and further includes: The slide plate 4 is slidably connected to the slide groove 102 opened on the inspection table 101; Support plate 401 is rotatably connected to slide plate 4. A camera 4011 is fixedly connected to one side of support plate 401, and a detection sleeve 3 is rotatably connected to the other side of support plate 401. Detection sleeve 3 is a double-layer sleeve; Multiple sets of first detection bladders 7 are fixedly connected to the outer shell of the detection sleeve 3. A first pressure sensor 701 is fixedly connected in the first detection bladder 7. Multiple sets of second detection bladders 8 are fixedly connected to the inner shell of the detection sleeve 3. A second pressure sensor 802 is fixedly connected in the second detection bladder 8. Motor 2 is fixedly mounted on mounting plate 1011. After removing the protective shell, bearing 201 inside motor 2 is exposed. Camera 4011 is aimed at and photographed bearing 201 and motor 2, and the photographed information is uploaded to computer platform. Computer platform analyzes and compares the eccentricity of bearing 201. The support plate 401 rotates 180° so that the detection sleeve 3 faces the motor 2. The slide plate 4 slides so that the detection sleeve 3 wraps around the bearing 201. The first detection bladder 7 and the second detection bladder 8 are inflated. The detection sleeve 3 rotates 360°. The first pressure sensor 701 and the second pressure sensor 802 of each group upload the pressure signal to the computer platform in real time. The computer platform analyzes and compares the eccentric distance and eccentric position of the bearing 201 again.

[0022] Reference Figure 3 , Figure 5 , Figure 8 In specific implementation, an electric push rod 103 is fixedly connected to the inspection platform 101. The drive end of the electric push rod 103 is fixedly connected to the slide plate 4. A second drive unit 402 is fixedly connected to the bottom of the slide plate 4. A drive rod 4021 is fixedly connected to the drive end of the second drive unit 402. The drive rod 4021 is fixedly connected to the support plate 401.

[0023] Reference Figure 7 , Figure 14 A first pressure relief valve 702 is fixedly connected to the first detection bladder 7, and a second pressure relief valve 801 is fixedly connected to the second detection bladder 8. In practice, both the first pressure relief valve 702 and the second pressure relief valve 801 are commercially available solenoid valves.

[0024] A drive cylinder 6 is fixedly connected to the detection sleeve 3. A slide plug 602 is slidably connected to the drive cylinder 6. An elastic pull rod 605 is fixedly connected to the slide plug 602. A guide plate 9 is rotatably connected to the detection sleeve 3 via a rotating shaft 901. When the slide plug 602 drives the elastic pull rod 605 to move, the guide plate 9 presses and limits the elastic pull rod 605. The elastic pull rod 605 deforms and tilts up. The top of the tilted elastic pull rod 605 extends into and hooks the bearing 201.

[0025] The detection sleeve 3 has a first connecting cavity 305 and a second connecting cavity 307. A first connecting pipe 3051 and a second connecting pipe 804 are fixedly connected to the detection sleeve 3. One end of the first connecting pipe 3051 is connected to the first connecting cavity 305, and the other end of the first connecting pipe 3051 is connected to the first detection capsule 7. One end of the second connecting pipe 804 is connected to the second connecting cavity 307, and the other end of the second connecting pipe 804 is connected to the second detection capsule 8.

[0026] An air supply chamber 301 is provided in the detection sleeve 3. A first air supply pipe 302, a second air supply pipe 303 and a third air supply pipe 304 are fixedly connected to the detection sleeve 3. The first air supply pipe 302, the second air supply pipe 303 and the third air supply pipe 304 are all connected to the air supply chamber 301. The first air supply pipe 302 is connected to the second connecting chamber 307. The second air supply pipe 303 is connected to the drive cylinder 6. The third air supply pipe 304 is connected to the first connecting chamber 305.

[0027] A gas storage chamber 403 is provided in the support plate 401. A sealing tube 404 is rotatably connected to the support plate 401. The sealing tube 404 is fixedly connected to the detection sleeve 3 and connects the gas storage chamber 403 and the gas delivery chamber 301.

[0028] Reference Figure 4 , Figure 9 An air pump 5 is fixedly connected to the support plate 401, and an air supply pipe 501 is fixedly connected to the air outlet end of the air pump 5. The air supply pipe 501 is connected to the air storage chamber 403. Reference Figure 6 In practice, one-way valves are installed on the sealing pipe 404, the first air supply pipe 302, the second air supply pipe 303, and the third air supply pipe 304.

[0029] A filling bladder 10 is fixedly connected to the detection sleeve 3, and an air supply pipe 803 is fixedly connected to the second detection bladder 8. The air supply pipe 803 is connected to the filling bladder 10. When the second detection bladder 8 deflates, the filling bladder 10 bulges up and pushes up the guide plate 9.

[0030] Reference Figure 1 , Figures 5-15 In practical use, the permanent magnet motor 2 to be inspected is fixedly installed on the mounting plate 1011 of the inspection platform 101, the protective shell of the motor is removed to expose the bearing 201 inside the motor; the electric push rod 103 is controlled to drive the slide plate 4 to slide, so that the camera 4011 is aligned with the bearing 201 and the motor 2. The camera 4011 uploads the image information to the computer platform, and the computer platform analyzes and compares the eccentricity distance between the bearing 201 and the drive shaft of the motor 2 to complete the preliminary inspection. Then, the second drive unit 402 is activated, and the support plate 401 is rotated 180° by the drive rod 4021, so that the detection sleeve 3 faces the motor 2; the electric push rod 103 is controlled again to drive the slide plate 4 to slide, so that the detection sleeve 3 wraps around the bearing 201. When the air pump 5 is started, gas enters the gas storage chamber 403 through the gas supply pipe 501, and then flows to the first detection bladder 7 and the second detection bladder 8 through the sealing pipe 404, the gas delivery chamber 301, the first connecting pipe 3051, and the second connecting pipe 804, respectively, causing the first detection bladder 7 and the second detection bladder 8 to inflate. At this time, the first drive unit 405 is started, which will drive the first gear 4051 to rotate. The first gear 4051 will drive the second gear 306 meshing with it to rotate. When the second gear 306 rotates, it will synchronously drive the detection sleeve 3 to rotate. When the detection sleeve 3 rotates, the first detection bladder 7 and the second detection bladder 8 on the detection sleeve 3 will detect the eccentricity of the bearing 201. When the bearing 201 is eccentric, the eccentric side will squeeze the first detection bladder 7 and the second detection bladder 8. At this time, the pressure in the first detection bladder 7 and the second detection bladder 8 will increase. After the detection sleeve 3 rotates one revolution, the first pressure sensor 701 and the second pressure sensor 802 will upload the pressure signal to the computer platform in real time. The computer platform will analyze and compare the eccentricity distance and eccentricity position of the bearing 201.

[0031] It should be noted that when the detection sleeve 3 rotates, the bearing 201 is fixed to ensure that the first detection chamber 7 and the second detection chamber 8 on the detection sleeve 3 can stably detect the outer and inner rings of the bearing 201.

[0032] It should also be noted that by performing rotation detection through multiple sets of first detection capsules 7 and second detection capsules 8, the first detection capsules 7 and second detection capsules 8 can pass through the eccentric position multiple times. By analyzing and comparing multiple sets of detection data, the detection accuracy can be improved and detection deviations can be prevented.

[0033] Reference Figure 6 An electromagnetic control valve is fixedly connected to the second air supply pipe 303.

[0034] When the bearing 201 is found to be severely eccentric, it needs to be removed. At this time, the electromagnetic control valve opens, and the gas in the air supply chamber 301 enters the drive cylinder 6 through the second air supply pipe 303. The input gas compresses and pushes the slide plug 602 to slide, thereby driving the elastic pull rod 605 to move. At the same time as the slide plug 602 moves, the gas in the second detection bladder 8 flows into the filling bladder 10 through the air supply pipe 803. At this time, the filling bladder 10 will push up the guide plate 9. The guide plate 9 will then compress the elastic pull rod 605, causing it to deform and tilt upwards. The tilted rod head extends into the gap between the inner and outer rings of the bearing 201, and the bent rod head will hook onto the outer ring wall of the bearing 201. At this time, the electric push rod 103 pulls the slide plate 4 to reset, thereby pulling the bearing 201 off the motor 2.

[0035] When the eccentricity of the bearing 201 is not severe and does not affect normal use, the solenoid control valve does not open. At this time, the first pressure relief valve 702 on the first detection chamber 7 opens and the second pressure relief valve 801 on the second detection chamber 8 opens, thereby completing the pressure relief of the first detection chamber 7 and the second detection chamber 8 for the next use.

[0036] An iron ring 6021 is fixedly connected to the slide plug 602, and an electromagnet 601 is fixedly connected to the drive cylinder 6. The iron ring 6021 and the electromagnet 601 are attracted to each other.

[0037] Reference Figure 13 After the slider 602 slides a certain distance, the electromagnet 601 is energized, and the iron ring 6021 on the slider 602 is attracted to the electromagnet 601. By attracting the iron ring 6021 through the electromagnet 601, the pull rod 605 can ensure the stability of the slider 602 when pulling the bearing 201.

[0038] Reference Figure 10 A tension spring 603 is fixedly connected to the slide plug 602, and the end of the tension spring 603 away from the slide plug 602 is fixedly connected to the inner wall of the drive cylinder 6.

[0039] In practical implementation, a pressure relief pipe 604 is fixedly connected to the side wall of the drive cylinder 6, and a one-way valve is installed on the pressure relief pipe 604.

[0040] With the tension spring 603 in place, when the drive cylinder 6 is depressurized, the tension spring 603 can quickly pull the slide plug 602 to reset.

[0041] A first drive unit 405 is fixedly connected to the support plate 401, and a first gear 4051 is fixedly connected to the drive end of the first drive unit 405. A second gear 306 is fixedly connected to the detection sleeve 3, and the first gear 4051 and the second gear 306 mesh with each other.

[0042] In practice, both the first drive unit 405 and the second drive unit 402 use commercially available servo motors.

[0043] Both the first detection capsule 7 and the second detection capsule 8 are elastic and wear-resistant capsules.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
