Abstract
Description
Technical Field
[0001] This invention relates to the field of magnetization technology, specifically to a horizontal magnetizer and its magnetization method. Background Technology
[0002] During the manufacturing process of an electric motor rotor, a magnetizing device is required to magnetize the rotor and impart it with magnetism. Currently, the most common type of magnetizer is the vertical magnetizer, which facilitates the support and positioning of the rotor. Specifically, the magnetizer includes a magnetizing cylinder and a support column that can be raised and lowered within the magnetizing cylinder. During magnetization, the support column extends out of the magnetizing cylinder to support the rotor. Then, the support column descends, pulling the rotor down to a preset height position within the magnetizing cylinder. The magnetizing cylinder is then opened to magnetize the rotor. After magnetization is complete, the support column extends again to push the rotor out of the magnetizing cylinder. After magnetization, the magnetic flux of the magnetized rotor is measured by a magnetization detection mechanism located at the top or upper part of the magnetizing cylinder. Therefore, the vertical magnetizer provides convenient support for the rotor and facilitates the positioning and magnetization of the rotor within the magnetizing cylinder. However, some equipment in the industry requires long rotors, such as rotors several meters long used in wind power generation. Using a vertical magnetizing device is not suitable for magnetizing such rotors. Vertical magnetizing devices are not convenient for feeding the rotor into the magnetizing device, and the overall height of the vertical magnetizing device is also required to be several meters high. In some sites, the height is limited, and the weight corresponding to the long rotor is also large. Furthermore, using support columns, such as those similar to those in small vertical magnetizing devices, to support the rotor to be magnetized presents technical issues that require further consideration regarding the stability of the rotor support and the design of the magnetizing cylinder. Summary of the Invention
[0003] In view of the above, it is necessary for the present invention to provide a horizontal magnetizer, so that the rotor can be placed horizontally inside the magnetizer, which facilitates the installation of long rotors and also benefits the spatial arrangement of the magnetizer.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A horizontal magnetizer includes a machine base, a clamping seat structure, a supporting seat structure, a magnetizing mechanism, a lifting mechanism, and a magnetizing detection mechanism. The machine base is equipped with a guide rail. The clamping seat structure includes a chuck seat, the supporting seat structure includes a top support, and the magnetizing mechanism includes a magnetizing cylinder. The chuck seat, top support, and magnetizing cylinder are slidably mounted on the guide rail. The chuck seat and top support are used to support both ends of the rotor. The magnetizing cylinder is located between the chuck seat and the top support for magnetizing the rotor. The lifting mechanism includes a support bracket, which is vertically and vertically mounted between the chuck seat and the top support for supporting the rotor during installation. The magnetizing detection mechanism includes a detection element, which is slidably mounted on the machine base and moves along the outside of the guide rail for detecting the magnetic flux of the magnetized rotor.
[0006] In addition, the present invention needs to provide a magnetization method having the aforementioned horizontal magnetizer.
[0007] A magnetization method for a horizontal magnetizer includes the following steps:
[0008] Move the chuck seat and the abutment seat to the preset distance;
[0009] The lifting mechanism is activated, and the support of the lifting mechanism is raised between the chuck seat and the abutment seat. The rotor is sent onto the support seat using external tools. Then, the height of the rotor is finely adjusted so that the center of both ends of the rotor is aligned with the chuck seat and the abutment seat.
[0010] When the pusher seat is activated, it slides toward the chuck seat, causing the rotor to press tightly against the pusher seat and the chuck seat. The support bracket moves horizontally together with the rotor. After one end of the rotor pushes against the chuck seat, the chuck seat clamps one end of the rotor.
[0011] The lifting mechanism's support bracket descends, moves horizontally to its reset position, and then descends to a slide rail below the machine platform surface.
[0012] The magnetization mechanism is activated, and the magnetizing cylinder moves along the slide rail, magnetizing the rotor segment by segment. After magnetization is completed, the magnetizing cylinder returns to its original position.
[0013] The magnetization detection mechanism is started, the rotor rotates, and the detection component moves gradually along the rotor's axial direction on the outer periphery of the rotor to detect the rotor segment by segment. After the detection is completed, the detection component returns to its original position.
[0014] The lifting mechanism supports the rotor, the chuck releases the rotor, and the chuck and the abutment move in opposite directions to loosen the clamping on the rotor. The magnetized rotor is then removed using external tools.
[0015] The beneficial effects of this invention are as follows:
[0016] The horizontal magnetizer provided by this invention supports the rotor during installation via a lifting mechanism and pushes the rotor axially via a support seat, facilitating the clamping of the rotor between the chuck seat and the support seat. During magnetization, the lifting mechanism descends, the magnetizing cylinder of the magnetizing mechanism is fitted onto the rotor, and the cylinder moves gradually to magnetize the rotor segment by segment. After magnetization, the chuck seat drives the rotor to rotate, and the magnetization detection mechanism moves step by step to detect the magnetic flux of the rotor segment by segment. After the detection is completed, the lifting mechanism is raised again to support the rotor, the chuck of the chuck seat is released, and the chuck seat and the support seat move in opposite directions to facilitate the removal of the rotor. The horizontal magnetizer provided by this invention allows for horizontal placement of the rotor during magnetization, which is beneficial for the placement of the rotor during magnetization and the removal after magnetization and detection. It also facilitates the site layout of the magnetizer, thus enabling convenient magnetization and detection of long rotors. Attached Figure Description

Detailed Implementation
[0036] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0037] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides a horizontal magnetizer, including a machine base 10, a clamping seat structure 20, a supporting seat structure 30, a magnetizing mechanism 40, a lifting mechanism 50, and a magnetizing detection mechanism 60. A guide rail 11 is provided on the machine base 10. The clamping seat structure 20 includes a chuck seat 21, the supporting seat structure 30 includes a supporting seat 31, and the magnetizing mechanism 40 includes a magnetizing cylinder 41. The chuck seat 21, the supporting seat 31, and the magnetizing cylinder 41 are slidably mounted on the guide rail 11. The chuck seat 21... 1. The abutment 31 is used to abut both ends of the rotor. The magnetizing cylinder 41 is located between the chuck seat 21 and the abutment 31 and is used to magnetize the rotor. The lifting mechanism 50 includes a support 51, which is located below the guide rail 11 and can be raised to be installed between the chuck seat 21 and the abutment 31 to support the rotor when it is installed. The magnetization detection mechanism 60 includes a detection element 61, which is slidably installed on the machine base 10 and moves along the outside of the guide rail 11 to detect the magnetic flux of the magnetized rotor.
[0038] The guide rail 11 has two parallel rails. The abutment 31 and the magnetizing cylinder 41 are slidably connected to the guide rail 11 and located on the upper side of the guide rail 11. The lifting mechanism 50 is installed below the guide rail 11. Preferably, the lifting mechanism 50 is slidably connected to the lower side of the guide rail 11, and the sliding of the abutment 31 and the magnetizing cylinder 41 on the upper side of the guide rail 11 and the sliding of the lifting mechanism 50 on the lower side of the guide rail 11 do not interfere with each other. Understandably, the middle part of the machine base 10 corresponding to the area below the guide rail 11 is a hollow space to accommodate the lifting mechanism 50 and the sliding space.
[0039] Please refer to Figure 3 , Figure 4 The chuck holder 21 includes a chuck 211 and a base 212. One end of the chuck 211 is a clamping head with a clamping opening that can be closed or opened to clamp one end of the rotor. The opening and closing of the clamping head is common in the industry, and its structure will not be described here. The other end of the chuck 211 is rotatably fitted onto the base 212 and extends out of the base 212. It is mounted on the base 212 via bearings. The base 212 is slidably mounted on the guide rail 11.
[0040] The chuck holder structure 20 includes a drive assembly 22 for driving the chuck 211 to rotate relative to the base 212 and for braking at any time. The drive assembly 22 includes a drive motor and a transmission belt. The drive motor is mounted on the base 212, and the output shaft of the drive motor is connected to the chuck 211 via the transmission belt, thereby driving the chuck 211 to rotate.
[0041] The chuck holder structure 20 includes a displacement adjustment mechanism 23, which includes an adjustment shaft 231 and a limiting seat 232. The end of the chuck 211 has a threaded hole of a preset length. The adjustment shaft 231 has a lead screw section that engages with the threaded hole of the chuck 211. The limiting seat 232 is fixed to the machine base 10 to block or install the adjustment shaft 231, restricting its axial movement. A handle is provided on the adjustment shaft 231. Rotating the handle causes the chuck 211, along with the seat body 212, to move along the slide rail 231. In this embodiment, the displacement adjustment mechanism 23 enables a short-distance displacement of the chuck 211 and cannot perform long-distance adjustments. It is mainly used to remove the chuck 211 from one end of the rotor when the rotor is released after magnetization.
[0042] Please see Figure 5The abutment seat 31 includes an abutment shaft 311 and a mounting body 312. The abutment shaft 311 is horizontally fixed on the mounting body 312 and is used to abut one end of the rotor. Specifically, a tapered tip is formed at the center of one end of the abutment shaft 311 to be aligned with the center point of the rotor end (usually the center point of the rotor end has a center hole or recess for fitting the tip). A guide (not shown) is formed on the bottom surface of the mounting body 312 to cooperate with the guide rail 11, so that the abutment seat 31 is slidably mounted on the guide rail 11.
[0043] The abutment structure 30 includes a drive assembly 32 for driving the abutment 31 to slide along the guide rail 11. The drive assembly 32 includes a motor and a lead screw. The motor is fixed on the machine base 10, and the lead screw is connected to the output shaft of the motor. The lead screw is arranged parallel to the guide rail 11. The bottom surface of the mounting body 312 has a threaded sleeve 3121 that cooperates with the lead screw. Thus, by driving the lead screw to rotate through the motor, the mounting body 312 is driven to move along the length of the lead screw, that is, the abutment 31 is driven to slide along the guide rail 11.
[0044] Thus, the chuck 211 of the chuck seat 21 clamps one end of the rotor, and the abutment shaft 311 of the abutment seat 31 abuts the other end of the rotor, so that the rotor can be suspended between the chuck seat 21 and the abutment seat 31, and the chuck 211 can be driven to rotate by the drive assembly 22, which can drive the rotor to rotate.
[0045] Please see Figure 6 The magnetizing cylinder 41 includes a cylinder base and a central channel 411 penetrating both ends of the cylinder base. The radial dimension of the central channel 411 is larger than that of the rotor to allow the rotor to pass through. A magnetizing device is provided on the cylinder base so that after the magnetizing cylinder 41 is fitted onto the rotor, the magnetizing device is activated to magnetize the rotor. Similarly, a guide member (not shown) is formed on the bottom surface of the cylinder base to cooperate with the guide rail 11, so that the magnetizing cylinder 41 can be slidably mounted on the guide rail 11.
[0046] The magnetizing mechanism 40 includes a moving component 42 for driving the magnetizing cylinder 41 to move along the guide rail 11. The moving component 42 has the same structure as the driving component 32, and is driven by a motor lead screw, which will not be described further here.
[0047] When the magnetizing mechanism 40 is used to magnetize the rotor, the magnetizing cylinder 41 is sleeved on the rotor. Since the length of the rotor is greater than the length of the magnetizing cylinder 41, the magnetizing cylinder 41 can only be moved step by step to magnetize the rotor segment by segment. The magnetizing cylinder 41 magnetizes the rotor segment corresponding to its cylinder length. After the magnetization is completed, the magnetizing cylinder 41 moves another cylinder length to magnetize the next rotor segment. This is done step by step until the entire length of the rotor is magnetized. The movement of the magnetizing cylinder 41 is driven by the moving component 42.
[0048] Please see Figures 7-12The lifting mechanism 50 supports the rotor when it is installed on the machine base 10, so that the chuck seat 21 and the abutment seat 31 can smoothly abut the two ends of the rotor. Usually, in the magnetization workshop, the rotor is hoisted and placed on the lifting mechanism 50 by a crane rope. The support bracket 51 of the lifting mechanism 50 supports the rotor and can move with the rotor (i.e., move axially). After the chuck seat 21 and the abutment seat 31 are abutted, the support bracket 51 of the lifting mechanism 50 is lowered and lowered below the plane of the guide rail 11, so that the magnetizing cylinder 41 can slide along the guide rail 11 to magnetize the rotor.
[0049] The lifting mechanism 50 includes a main lifting component 52, a lifting seat 53, a translation structure 54, a translation plate reset structure 55, and a secondary lifting component 56. The main lifting component 52 is installed inside the machine base 10 and is used to drive the lifting seat 53 to rise and fall. The translation structure 54 includes a translation plate 541, which is slidably installed on the lifting seat 53. The translation plate reset structure 55 is used to reset the translation plate 541 after translation. The secondary lifting component 56 is installed on the translation plate 541, and the support bracket 51 is installed on it for fine adjustment of the height of the support bracket 51.
[0050] When the rotor is installed on the machine base 10, the main lifting assembly 52 drives the lifting seat 53 to rise to a preset height, that is, the translation plate 541, translation plate reset structure 55, secondary lifting assembly 56, and support bracket 51 set on the lifting seat 53 all rise to the preset height; then the rotor is placed on the support bracket 51, and then the secondary lifting assembly 56 is activated, driving the support bracket 51 to rise and fall slightly, so that the two ends of the rotor are aligned with the chuck seat 21 and the abutment seat 31; then the abutment seat 31 is activated, moving towards the chuck seat 21, and the tip of the abutment seat 31 abuts the rotor, driving the rotor to translate, which will also drive the support bracket 51 supporting the rotor to translate, and the other end of the rotor enters the clamping head of the chuck seat 21, and the clamping head clamps the other end of the rotor; in this way, the rotor is stably clamped between the chuck seat 21 and the abutment seat 31. When the support bracket 51 translates, the support bracket 51, together with the secondary lifting assembly 56 and the translation plate 541, translates relative to the lifting seat 53. After the rotor is stably clamped, the secondary lifting assembly 56 drives the support bracket 51 to descend, disengaging from the rotor and thus freeing it from the rotor's pressure. Under the action of the translation plate reset structure 55, the translation plate 541, together with the secondary lifting assembly 56 and the support bracket 51, returns to its original position on the lifting seat 53.
[0051] The main lifting assembly 52 includes a fixed frame 521, a lifting drive motor 522, a vertical shaft 523, and a threaded sleeve 524. The fixed frame 521 is slidably connected to the bottom surface of the guide rail 11. The lifting drive motor 522 is fixedly mounted horizontally within the fixed frame 521. The vertical shaft 523 is rotatable around its axis and fixedly mounted axially within the fixed frame 521. The outer circumferential surface of the vertical shaft 523 is threaded. The threaded sleeve 524 is fitted onto the vertical shaft 523 and threadedly engages with it. The output shaft of the lifting drive motor 522 meshes with the spur gear of the vertical shaft 523, thereby driving the vertical shaft 523 to rotate via the lifting drive motor 522.
[0052] The lifting seat 53 includes a main frame 531 and a fixed plate 532 fixedly connected to one side of the main frame 531. The fixed plate 532 is fixedly connected to a threaded sleeve 524, so that the threaded sleeve 524 can be raised and lowered along the vertical shaft 523 by rotating the vertical shaft 523, thereby driving the main frame 531 to rise and fall. Understandably, a guide rail structure is also provided between the fixed plate 532 and the fixed frame 521 to guide the main frame 531 to rise and fall along the fixed frame 521. In this embodiment, the fixed frame 521 is provided with a guide rail, and a slider is provided on the guide rail. The slider is fixedly connected to the fixed plate 532.
[0053] The translation structure 54 is used to allow the support bracket 51 and the rotor to move along the rotor axis when they are assembled. Otherwise, if the support bracket 51 cannot move, only the rotor will move, which will cause friction damage to the rotor surface.
[0054] The translation structure 54 includes the translation plate 541 and a guide structure. The translation plate 541 is slidably mounted on the top surface of the main frame 531, and the translation plate 541 and the main frame 531 are connected by the guide structure. Specifically, a guide strip 5311 is fixedly provided on the top surface of the main frame 531, and a sliding block 5312 that can slide along the guide strip 5311 is sleeved on the guide strip 5311. The sliding block 5312 is fixedly connected to the bottom surface of the translation plate 541.
[0055] The translation plate reset structure 55 includes a guide rod 551, a spring 552, and a sliding sleeve 553. The guide rod 551 is mounted on the top surface of the main frame 531 through end seats at both ends, and is parallel to the sliding direction of the translation plate 541. The spring 552 is sleeved on the guide rod 551 and is elastically compressed, and can be held between the two end seats. The sliding sleeve 553 is sleeved on the guide rod 551 and connected to the spring 552, preferably located in the middle of the guide rod 551. The sliding sleeve 553 is fixed to the bottom surface of the translation plate 541. Thus, when the translation plate 541 moves, it will drive the sliding sleeve 553 to move, causing the spring 552 to deform. The spring 552 will provide the elastic force to reset the sliding sleeve 553.
[0056] Preferably, in order to facilitate the uninterrupted sliding of the sliding sleeve 553, a clearance groove 5313 is provided on the top surface of the main frame 531, which allows the lower end of the sliding sleeve 553 to extend into the clearance groove 5313, facilitating the sliding of the sliding sleeve 553 and providing a certain guiding effect for the sliding of the sliding sleeve 553.
[0057] The secondary lifting assembly 56 is mounted on the translation plate 541 and is used for fine-tuning the lifting height of the support bracket 51. The secondary lifting assembly 56 includes a lifting frame 561, a lifting rod 562, and a drive assembly 563. The lifting frame 561 is movably mounted on the translation plate 541, and its top end is connected to the support bracket 51. The lifting rod 562 is fixedly mounted on the lifting frame 561. The drive assembly 563 is mounted on the translation plate 541 and engages with the lifting rod 562 to drive the lifting rod 562 to rise and fall, thereby driving the lifting frame 561 to rise and fall accordingly.
[0058] The lifting frame 561 includes a top plate 5611 and a plurality of lifting guide columns 5612 fixedly connected to the bottom surface of the top plate 5611. The lifting guide columns 5612 can be vertically moved through a translation plate 541. Understandably, the translation plate 541 is provided with guide sleeves that cooperate with the lifting guide columns 5612 to ensure stable lifting of the lifting guide columns 5612. Furthermore, the bottom ends of the plurality of lifting guide columns 5612 are fixedly connected to a fixing plate to stabilize the relative positions of the lifting guide columns 5612, thereby improving the lifting stability of the entire lifting frame 561.
[0059] The lifting rod 562 is fixedly connected to the lifting frame 561. In this embodiment, the lifting rod 562 is securely connected to the top plate 5611 of the lifting frame 561 via a lower connecting plate 502 and an upper connecting plate 503. The connection method of the upper connecting plate 503 and the lower connecting plate 502 can improve the stability of the connection and the distribution of the lifting force area. Specifically, a central hole 501 is provided on the top plate 5611. The lower connecting plate 502 is connected to the top of the lifting rod 562. The size of the lower connecting plate 502 roughly corresponds to the size of the central hole 501 and is accommodated in the central hole 501. The size of the upper connecting plate 503 is larger than the size of the lower connecting plate 502. The upper connecting plate 503 covers the central hole 501 and is fixed to the top plate 5611 by a pin, and is also fixed to the lower connecting plate 502 by a pin. Thus, the lifting rod 562 is stably connected to the top plate 5611, and when the lifting rod 562 is pushed up, the force on the top plate 5611 is uniform.
[0060] The drive assembly 563 includes a connecting seat 5631 and a power component 5632. The connecting seat 5631 is fixedly connected to the bottom surface of the translation plate 541, and the power component 5632 is fixedly connected to the connecting seat 5631. The power component 5632 is a motor. The connecting seat 5631 is provided with a vertical channel structure so that the lifting rod 562 can pass vertically through the connecting seat 5631 and upward through the translation plate 541 to be fixedly connected to the lower connecting plate 502. The output shaft of the power component 5632 is perpendicularly engaged with the lifting rod 562 to drive the lifting rod 562 to rise and fall.
[0061] The support bracket 51 has a V-shaped lifting opening on its top surface to support the rotor. The support bracket 51 is fixedly mounted on the top plate 5611 of the lifting frame 561 and rises and falls together with the lifting frame 561. In this embodiment, the bottom surface of the support bracket 51 has a receiving groove to accommodate the upper connecting plate 503, so that the bottom surface of the support bracket 51 and the top surface of the top plate 5611 are in planar contact, improving the uniformity of the lifting force on the support bracket 51.
[0062] Understandably, in order to accurately determine the lifting height of the support 51, the lifting mechanism 50 further includes a height detection structure 57, which determines the position or height of the support 51 in real time. The height detection structure 57 includes a lifting shaft 571 and a detection body 572. The lifting shaft 571 is vertically connected to the lifting frame 561, and its lifting is driven by the lifting of the lifting frame 561. The detection body 572 detects the height of the lifting shaft 571 in real time and provides feedback. In this embodiment, the height detection structure 57 uses an electric cylinder structure capable of detecting piston height. A mounting plate 573 is installed on the bottom surface of the translation plate 541, and the electric cylinder body is mounted on the mounting plate 573. The piston rod of the electric cylinder passes through the translation plate 541 and connects to the top plate 5611 of the lifting frame 561.
[0063] Understandably, for rotors of the same length, there is no need to adjust the position of the lifting mechanism 50 on the guide rail 11. However, for the installation of different types of rotors, such as rotors of different lengths, it is necessary to adjust the position of the lifting mechanism 50 on the guide rail 11 so that the lifting mechanism 50 is supported at the center of the rotor. Thus, it is necessary to move the lifting mechanism 50 on the guide rail 11.
[0064] The lifting mechanism 50 further includes a translation drive mechanism 58, which includes a lead screw 581, a guide block 582 slidably sleeved on the lead screw 581, and a handwheel transmission structure 583 for driving the lead screw 581 to rotate. The lead screw 581 is parallel to the guide rail 11 and is mounted on the machine base 10. The guide block 582 is fixed to the top surface of the fixed frame 521. The handwheel transmission structure 583 has a handwheel. By holding the handwheel and rotating it, the lead screw 581 is driven to rotate, which in turn drives the guide block 582 to move on the lead screw 581, and correspondingly drives the fixed frame 521 to move, thereby adjusting the position of the lifting mechanism 50 on the guide rail 11.
[0065] Please see Figure 13 , Figure 14 The magnetization detection mechanism 60 includes a mounting base 62, a driving mechanism 63, and a guide rail 64. The mounting base 62 is used to mount the detection component 61, so that after the detection component 61 is installed, its detection head faces the outer periphery of the rotor and maintains a preset distance from the outer periphery of the rotor. The driving mechanism 63 is used to drive the mounting base 62 to move, and can be driven by a cylinder or a motor. In this embodiment, a motor screw structure is used, including a magnetization detection motor 631, a screw 632 connected to the output end of the magnetization detection motor 631, and a bushing 633 sleeved on the screw 632. The magnetization detection motor 631 is mounted on the machine base 10, and the screw 632 is mounted on the table surface of the machine base 10, located outside the guide rail 11 and parallel to the guide rail 11. The bushing 633 is fixedly connected to the mounting base 62. The magnetizing detection motor 631 drives the lead screw 632 to rotate, causing the bushing 633 to move along the lead screw 632, thereby causing the mounting base 62 to move along the outer side of the guide rail 11. This enables the detection element 61 to move axially along the rotor, performing magnetic flux detection on the outer circumference of the rotor. Understandably, during detection, the rotor rotates, and the detection element 61 moves gradually to detect the rotor segment by segment.
[0066] The guide rail 64 and the parallel guide rail 11 are set on the table of the machine base 10. The guide rail 64 cooperates with the sliding groove set at the bottom of the mounting base 62 to support the mounting base 62 together with the bushing 633, improve the stability of the mounting base 62, and guide the mounting base 62 to slide.
[0067] Understandably, the horizontal magnetizer also includes a control panel 70, which has a control system and a control panel for controlling the operation of the support structure 30, the magnetizing mechanism 40, the lifting mechanism 50, and the magnetizing detection mechanism 60.
[0068] Please see Figures 15-17 When using the horizontal magnetizer of this invention to magnetize the rotor, the magnetization method is as follows:
[0069] Move the chuck seat 21 and the abutment seat 31 to the preset distance;
[0070] The lifting mechanism 50 is activated; the support 51 of the lifting mechanism 50 is raised between the chuck seat 21 and the abutment seat 31. The rotor is sent to the support 51 by external tools. The height of the rotor is finely adjusted according to the diameter of the rotor so that the center of both ends of the rotor is aligned with the chuck seat 21 and the abutment seat 31.
[0071] When the abutment 31 is activated, the abutment 31 slides toward the chuck seat 21, so that the rotor is pressed tightly between the abutment 31 and the chuck seat 21. The support 51 moves horizontally together with the rotor. After one end of the rotor is pushed into the chuck seat 21, the chuck seat 21 clamps one end of the rotor.
[0072] The support 51 of the lifting mechanism 50 descends, the support 51 moves horizontally to reset, and the support 51 descends to the guide rail 11 below the surface of the machine platform 10.
[0073] When the magnetization mechanism 40 is started, its magnetization cylinder 41 moves along the guide rail 11, magnetizing the rotor segment by segment. After magnetization is completed, the magnetization cylinder 41 returns to its original position.
[0074] The magnetization detection mechanism 60 is started, the rotor rotates, and the detection element 61 moves gradually along the axial direction of the rotor to detect the rotor segment by segment. After the detection is completed, the detection element 61 returns to its original position.
[0075] The support 51 of the lifting mechanism 50 is raised to support the rotor. The chuck seat 21 and the abutment seat 31 move in opposite directions to loosen the clamping on the rotor. The magnetized rotor is then removed using an external tool.
[0076] Understandably, when changing rotors of different lengths, it further includes adjusting the initial distance between the chuck seat 21 and the abutment seat 31, and adjusting the position of the lifting mechanism 50 on the guide rail 11. By moving the lifting mechanism 50 on the guide rail 11, the support bracket 51 is supported at the center position of the rotor of the corresponding length.
[0077] In summary, the horizontal magnetizer of the present invention supports the rotor during rotor installation via a lifting mechanism 50 and tightens the rotor axially via a support seat. The two ends of the rotor are respectively supported between the chuck seat 21 and the support seat 31. The magnetizing cylinder 41 of the magnetizing mechanism 40 is fitted onto the rotor and moves step by step to magnetize the rotor segment by segment. After magnetization, the rotor is rotated by the chuck seat 21, and the detection element 61 of the magnetization detection mechanism 60 moves step by step to detect the magnetic flux of the rotor segment by segment. In this way, it is convenient to magnetize and detect long rotors. The horizontal magnetizer of the present invention allows the rotor to be placed horizontally for magnetization, which is beneficial for the placement of the rotor during magnetization and for the site layout of the magnetizer, greatly facilitating the magnetization of long rotors.
[0078] The embodiments described above merely illustrate implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
