Description

Technical Field

[0001] The invention relates to the technical field of magnetization, in particular to a horizontal magnetizer and a magnetization method thereof. Background Art

[0002] During the manufacturing process of the motor rotor, a magnetizing device is required to magnetize the rotor to make it magnetic. The most common magnetizing machine at present is a vertical magnetizing machine, which can facilitate the bearing and positioning of the rotor. Specifically, the magnetizing machine includes a magnetizing cylinder and a support column that can be lifted and lowered in the magnetizing cylinder. During magnetization, the support column extends out of the magnetizing cylinder to receive the rotor, and then the support column descends, driving the rotor to descend to a preset height position in the magnetizing cylinder. The magnetizing cylinder is opened to magnetize the rotor. After the magnetization is completed, the support column is extended again to push the rotor out of the magnetizing cylinder. In this way, the magnetization is completed. After magnetization, the magnetization detection mechanism set at the top or upper part of the magnetizing cylinder is used to detect the magnetic flux of the magnetized rotor. It can be seen that the vertical magnetizing device is convenient for supporting the rotor and is convenient for positioning and magnetizing the rotor in the magnetizing cylinder. However, some equipment in the industry requires long rotors, such as several meters long rotors for wind power generation. It is not suitable to use a vertical magnetizing device for magnetization. It is necessary to develop a horizontal magnetizing device. When developing a horizontal magnetizing device, it is necessary to consider the rotor load and the rotor position adjustment, such as the height position of the rotor and the horizontal position of the rotor. Therefore, it is necessary to design a lifting mechanism that facilitates the rotor position adjustment. Summary of the invention

[0003] In view of the above, it is necessary for the present invention to provide a lifting mechanism for a horizontal magnetizer that is convenient for installing and adjusting the rotor.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A lifting mechanism of a horizontal magnetizer includes a support bracket, a main lifting assembly, a lifting seat, a translation structure, a translation plate reset structure and a secondary lifting assembly. The main lifting assembly is used to drive the lifting seat to rise and fall. The translation structure includes a translation plate, which can be translationally installed on the lifting seat. The translation plate reset structure is used to reset the translation plate after translation. The secondary lifting assembly is installed on the translation plate, on which the support bracket is installed, and is used to drive the support bracket to rise and fall.

[0006] In addition, the present invention needs to provide a horizontal magnetizer having the jacking mechanism.

[0007] A horizontal magnetizing machine comprises a machine platform, a clamping seat structure, a supporting seat structure and a magnetizing mechanism. A guide rail is arranged on the machine platform. The clamping seat structure comprises a chuck seat, the supporting seat structure comprises a supporting seat, and the magnetizing mechanism comprises a magnetizing cylinder. The chuck seat, the supporting seat and the magnetizing cylinder can be slidably mounted on the guide rail. The chuck seat and the supporting seat are used to resist the two ends of a rotor. The magnetizing cylinder is located between the chuck seat and the supporting seat and is used to magnetize the rotor. The horizontal magnetizing machine also comprises the lifting mechanism. The supporting support of the lifting mechanism can be lifted and lowered between the chuck seat and the supporting seat to support the rotor when installing the rotor. The supporting seat and the magnetizing cylinder can be slidably connected to the upper side of the guide rail, and the lifting mechanism can be slidably connected to the lower side of the guide rail.

[0008] The beneficial effects of the present invention are:

[0009] The horizontal magnetizer provided by the present invention adopts the jacking mechanism, which can lift the rotor when the rotor is installed, and fine-tune the height of the rotor so that the rotor is accurately aligned with the chuck seat and the abutment seat. Moreover, when the rotor moves, its support bracket can move together with the rotor without causing friction damage to the rotor. The two ends of the rotor are abutted between the chuck seat and the abutment seat. When the support for the rotor is released, the support bracket can return to its original position. The jacking mechanism realizes accurate installation of the rotor with high installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0030] like Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a horizontal magnetizing machine, including a machine platform 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, the machine platform 10 is provided with a guide rail 11, the clamping seat structure 20 includes a chuck seat 21, the supporting seat structure 30 includes a supporting seat 31, 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, and the chuck seat 21 is provided with a guide rail 11. 1. The abutting seat 31 is used to abut the two ends of the rotor. The magnetizing cylinder 41 is located between the chuck seat 21 and the abutting seat 31 and is used to magnetize the rotor. The lifting mechanism 50 includes a support bracket 51, which is located below the guide rail 11 and can be lifted to be installed between the chuck seat 21 and the abutting seat 31 to support the rotor when installing the rotor. The magnetization detection mechanism 60 includes a detection member 61, which can be slidably installed on the machine table 10 and move along the outer side of the guide rail 11 to perform magnetic flux detection on the magnetized rotor.

[0031] The guide rail 11 has two parallel rails, the abutting seat 31 and the magnetizing cylinder 41 are slidably connected to the guide rail 11 and are located on the upper side of the guide rail 11, and 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 abutting seat 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. It can be understood that the middle part of the machine 10 corresponding to the lower side of the guide rail 11 is a hollow space to accommodate the lifting mechanism 50 and the sliding space.

[0032] Please refer to Figure 3 , Figure 4 The chuck seat 21 includes a chuck 211 and a seat body 212. One end of the chuck 211 is a clamping head. The clamping head has 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 commonly used in the industry, and its structure is not described here. The other end of the chuck 211 is rotatably sleeved on the seat body 212 and extends out of the seat body 212. For example, it is installed on the seat body 212 through a bearing. The seat body 212 is slidably installed on the guide rail 11.

[0033] The clamp seat structure 20 includes a rotation drive assembly 22, which is used to drive the chuck 211 to rotate relative to the seat body 212, and can brake at any time. The rotation drive assembly 22 includes a rotation drive motor and a transmission belt. The drive motor is installed on the seat body 212, and the output shaft of the drive motor is connected to the chuck 211 through the transmission belt, so that the chuck 211 can be driven to rotate.

[0034] The clamp seat structure 20 includes a displacement adjustment mechanism 23, which includes an adjustment shaft 231 and a limit seat 232. A thread hole of a preset length is provided at the end of the chuck 211. The adjustment shaft 231 has a screw section, which cooperates with the thread hole of the chuck 211 through the screw section. The limit seat 232 is fixed on the machine 10 and is used to resist the adjustment shaft 231 or install the adjustment shaft 231 to limit the axial movement of the adjustment shaft 231. A handle is provided on the adjustment shaft 231. By rotating the adjustment shaft 231 with the handle, the chuck 211 and the seat body 212 will move along the slide rail 231. In this embodiment, the displacement adjustment mechanism 23 realizes the displacement of the chuck 211 over a short distance, and cannot be adjusted over a long distance. It is mainly used to withdraw the chuck 211 from one end of the rotor when the rotor is released after magnetization.

[0035] See also Figure 5 The abutting seat 31 includes an abutting shaft 311 and a mounting body 312. The abutting shaft 311 is fixedly mounted horizontally on the mounting body 312 to abut one end of the rotor. Specifically, a conical tip is formed at the center of one end of the abutting shaft 311 to align with the center point of the rotor end (usually a center hole or depression is formed at the center point of the rotor end to match the tip). A guide member (not shown) is formed on the bottom surface of the mounting body 312 to cooperate with the guide rail 11, so that the abutting seat 31 can be slidably mounted on the guide rail 11.

[0036] The support seat structure 30 includes a driving assembly 32 for driving the support seat 31 to slide along the guide rail 11. The driving assembly 32 includes a motor and a screw, the motor is fixed on the machine 10, the screw is connected to the output shaft of the motor, and the screw is arranged parallel to the guide rail 11, and a threaded sleeve 3121 is formed on the bottom surface of the mounting body 312 to cooperate with the screw, so that the motor drives the screw to rotate and drives the mounting body 312 to move along the length direction of the screw, that is, drives the support seat 31 to slide along the guide rail 11.

[0037] In this way, the chuck 211 of the chuck seat 21 clamps one end of the rotor, and the abutting shaft 311 of the abutting seat 31 abuts the other end of the rotor, so that the rotor can be suspended between the chuck seat 21 and the abutting seat 31, and the chuck 211 is driven to rotate by the driving assembly 22, which can drive the rotor to rotate.

[0038] See also Figure 6The magnetizing cylinder 41 includes a cylinder seat and a central channel 411 that passes through both ends of the cylinder seat. The radial dimension of the central channel 411 is larger than that of the rotor so that the rotor can pass through. A magnetizing device is provided on the cylinder seat so that after the magnetizing cylinder 41 is sleeved on the rotor, the magnetizing device is turned on to magnetize the rotor. Similarly, a guide member (not shown) is formed on the bottom surface of the cylinder seat to cooperate with the guide rail 11 so that the magnetizing cylinder 41 can be slidably installed on the guide rail 11.

[0039] The magnetizing mechanism 40 includes a moving assembly 42 for driving the magnetizing cylinder 41 to move along the guide rail 11. The moving assembly 42 has the same structure as the driving assembly 32, and is driven by a motor screw, which will not be described here.

[0040] 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 section by section. The magnetizing cylinder 41 magnetizes the rotor section corresponding to its cylinder length. After the magnetization is completed, the magnetizing cylinder 41 moves another cylinder length to magnetize the next rotor section. It moves step by step in this way until the magnetization of the entire rotor length is completed. The movement of the magnetizing cylinder 41 is driven by the moving component 42.

[0041] See also Figure 7-Figure 12 The lifting mechanism 50 is used to support the rotor when the rotor is installed on the machine 10, so that the chuck seat 21 and the abutting seat 31 can smoothly abut the two ends of the rotor. Usually, in the magnetization workshop, the rotor is hoisted by the rope of the crane and placed on the lifting mechanism 50. The support bracket 51 of the lifting mechanism 50 supports the rotor and can move with the rotor (i.e., axial movement), otherwise it will not support stably or cause friction damage to the rotor surface. After the chuck seat 21 and the abutting seat 31 are abutted, the support bracket 51 of the lifting mechanism 50 descends and is lower than the plane of the guide rail 11, so that the magnetization cylinder 41 can slide along the guide rail 11 to magnetize the rotor.

[0042] 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 in the machine platform 10 and is used to drive the lifting seat 53 to move up and down. The translation structure 54 includes a translation plate 541, which is translationally 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, on which the support bracket 51 is installed, and is used to fine-tune the height of the support bracket 51.

[0043] When the rotor is installed on the machine 10, the main lifting assembly 52 drives the lifting seat 53 to rise to a preset height, that is, the translation plate 541, the translation plate reset structure 55, the secondary lifting assembly 56 and the 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 started to drive the support bracket 51 to rise and fall finely, so that the two ends of the rotor are aligned with the chuck seat 21 and the abutting seat 31; then the abutting seat 31 is started and moves toward the chuck seat 21, and the top of the abutting seat 31 will abut the rotor, drive the rotor to translate, and drive the support bracket 51 supporting the rotor to translate together, 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 abutting 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, breaking away from the support for the rotor, that is, breaking away from the pressure on the rotor. 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.

[0044] 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 fixed frame 521 includes a bottom frame 5211, a top wall 5212 and a connecting wall 5213 connected between the bottom frame 5211 and the top wall 5212. The lifting drive motor 522 is fixedly arranged in the bottom frame 5211, and the vertical shaft 523 is arranged vertically between the bottom frame 5211 and the top wall 5212 so as to be rotatable around the axis. The outer peripheral surface of the vertical shaft 523 is formed with threads. The threaded sleeve 524 is sleeved on the vertical shaft 523 and is threadedly matched with the vertical shaft 523. The output shaft of the lifting drive motor 522 is meshed with the vertical shaft 523 by spur teeth, so that the vertical shaft 523 is driven to rotate by the lifting drive motor 522.

[0045] The lifting seat 53 includes a main frame 531 and a fixing plate 532 fixedly connected to one side of the main frame 531. The fixing plate 532 is fixedly connected to the threaded sleeve 524, so that the threaded sleeve 524 is lifted and lowered along the vertical shaft 523 by rotating the vertical shaft 523, thereby driving the main frame 531 to lift and lower. It can be understood that a guide rail structure is also provided between the fixing plate 532 and the fixing frame 521, which is used to guide the main frame 531 to lift and lower along the fixing frame 521. In this embodiment, a guide rail is vertically provided on the fixing frame 521, and a slider is provided on the guide rail, and the slider is fixed to the fixing plate 532.

[0046] The translation structure 54 is used to allow the support bracket 51 to move along the axial direction of the rotor together with the rotor when assembled with the rotor. Otherwise, if the support bracket 51 cannot move, only the rotor will move, which will cause friction damage to the rotor surface.

[0047] The translation structure 54 includes the translation plate 541 and the guide structure. The translation plate 541 is slidably mounted on the top surface of the main frame 531. The translation plate 541 and the main frame 531 are connected via the guide structure. Specifically, a guide bar 5311 is fixedly disposed on the top surface of the main frame 531. A sliding block 5312 that can slide along the guide bar 5311 is sleeved on the guide bar 5311. The sliding block 5312 is fixedly connected to the bottom surface of the translation plate 541.

[0048] The translation plate reset structure 55 includes a guide rod 551, a spring 552 and a sliding sleeve 553. The guide rod 551 is installed on the top surface of the main frame 531 by setting 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 elastically compressed, and can be supported 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. In this way, when the translation plate 541 moves, it will drive the sliding sleeve 553 to move, so that the spring 552 is deformed, and the spring 552 will provide elastic force to reset the sliding sleeve 553.

[0049] Preferably, in order to facilitate the sliding of the sliding sleeve 553 without interference, a clearance groove 5313 is opened on the top surface of the main frame 531, allowing the lower end of the sliding sleeve 553 to extend into the clearance groove 5313, thereby facilitating the sliding of the sliding sleeve 553 and providing a certain guiding effect for the sliding of the sliding sleeve 553.

[0050] The secondary lifting assembly 56 is installed on the translation plate 541 and is used to fine-tune the lifting height of the support bracket 51. The secondary lifting assembly 56 includes a lifting frame 561, a lifting rod 562, and a driving assembly 563. The lifting frame 561 is installed on the translation plate 541 in a liftable manner, and its top end is connected to the support bracket 51. The lifting rod 562 is fixedly installed on the lifting frame 561. The driving assembly 563 is installed on the translation plate 541 and meshed with the lifting rod 562 to drive the lifting rod 562 to move up and down, and correspondingly drive the lifting frame 561 to move up and down.

[0051] The lifting frame 561 includes a top plate 5611 and a plurality of lifting guide posts 5612 fixedly connected to the bottom surface of the top plate 5611. The lifting guide posts 5612 can be lifted and lowered through the translation plate 541, and the bottom ends are inserted into the main frame 531. It can be understood that the translation plate 541 is provided with guide sleeves to cooperate with the lifting guide posts 5612, so that the lifting guide posts 5612 can be lifted and lowered stably; further, the bottom ends of the plurality of lifting guide posts 5612 are fixedly connected to a fixing plate to stabilize the relative positions of the lifting guide posts 5612, thereby improving the lifting stability of the entire lifting frame 561.

[0052] The lifting rod 562 is fixedly connected to the lifting frame 561. In this embodiment, the lifting rod 562 is fixedly connected to the lifting frame 561 through a connecting plate structure. The connection mode of the connecting structure and the connection can improve the stability of the connection and the dispersion of the lifting force area. Specifically, the connecting plate structure includes a lower connecting plate 502 and an upper connecting plate 503. A center hole 501 is opened 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 center hole 501 and is accommodated in the center 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 center hole 501 and is fixed to the top plate 5611 through a pin, and is fixed to the lower connecting plate 502 through a pin. In this way, the lifting rod 562 is stably connected to the top plate 5611, and when the lifting rod 562 is pushed up, the top plate 5611 is evenly stressed.

[0053] The driving assembly 563 includes a connecting seat 5631 and a power piece 5632. The connecting seat 5631 is fixedly connected to the bottom surface of the translation plate 541. The power piece 5632 is fixedly connected to the connecting seat 5631. The power piece 5632 adopts a motor. A vertical channel structure is provided on the connecting seat 5631, so that the lifting rod 562 can vertically pass through the connecting seat 5631 and pass through the translation plate 541 upwards to be fixed to the lower connecting plate 502. The output shaft of the power piece 5632 is vertically meshed with the lifting rod 562 to drive the lifting rod 562 to rise and fall.

[0054] The top surface of the support bracket 51 is provided with a V-shaped lifting opening for lifting the rotor. The support bracket 51 is fixedly mounted on the top plate 5611 of the lifting frame 561 and is lifted and lowered together with the lifting frame 561. In this embodiment, the bottom surface of the support bracket 51 is provided with a receiving groove for accommodating 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 a flat fit, thereby improving the uniformity of the lifting force of the support bracket 51.

[0055] It can be understood that in order to accurately know the lifting height of the support bracket 51 fine-tuned, the lifting mechanism 50 further includes a height detection structure 57, through which the position or height of the lifting of the support bracket 51 can be known in real time. The height detection structure 57 includes a lifting shaft 571 and a detection body 572. The lifting shaft 571 is connected to the lifting frame 561 in a liftable manner, and is driven to lift by the lifting frame 561. The detection body 572 is installed on the translation plate 541 to detect the height of the lifting shaft 571 in real time and provide feedback. In this embodiment, the height detection structure 57 adopts an electric cylinder structure that can detect the height of the piston. A mounting plate 573 is installed on the bottom surface of the translation plate 541, and the main body of the electric cylinder is installed on the mounting plate 573. The piston rod of the electric cylinder passes through the translation plate 541 and is connected to the top plate 5611 of the lifting frame 561.

[0056] It can be understood that 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 the installation of 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 position of the rotor. In this case, the lifting mechanism 50 needs to be moved on the guide rail 11.

[0057] The lifting mechanism 50 further includes a translation drive mechanism 58, which includes a lead screw 581, a guide block 582 slidably mounted on the lead screw 581, and a handwheel transmission structure 583 for driving the lead screw 581 to rotate. The lead screw 581 is arranged on the machine platform 10 in parallel with the guide rail 11, and 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, and the guide block 582 is driven to move on the lead screw 581, and the fixed frame 521 is correspondingly driven to move, thereby adjusting the position of the lifting mechanism 50 on the guide rail 11.

The mounting seat 62 is used to mount the detection member 61, so that after the detection member 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 seat 62 to move, and can be driven by a cylinder or a motor. In this embodiment, a motor screw structure is adopted, including a magnetization detection motor 631, a wire shaft 632 connected to the output end of the magnetization detection motor 631, and a shaft sleeve 633 sleeved on the wire shaft 632. The magnetization detection motor 631 is installed on the machine 10, and the wire shaft 632 is mounted on the table of the machine 10, located on the outer side of the guide rail 11 and parallel to the guide rail 11. The shaft sleeve 633 is fixedly connected to the mounting seat 62, and the magnetization detection motor 631 drives the wire shaft 632 to rotate, driving the shaft sleeve 633 to move along the wire shaft 632, thereby driving the mounting seat 62 to move along the outer side of the guide rail 11, so that the detection member 61 moves along the axial direction of the rotor to detect the magnetic flux on the outer periphery of the rotor. It can be understood that during the detection, the rotor rotates, and the detection member 61 moves step by step to detect the rotor section by section.

[0059] The guide rail 64 is parallel to the guide rail 11 and is arranged on the table surface of the machine 10 . The guide rail 64 cooperates with the slide groove arranged at the bottom of the mounting seat 62 to cooperate with the shaft sleeve 633 to support the mounting seat 62 , thereby improving the stability of the mounting seat 62 and guiding the mounting seat 62 to slide.

[0060] It can be understood that the horizontal magnetizing machine further includes a control panel 70 having a control system and a control panel for controlling the operation process of the support structure 30 , the magnetizing mechanism 40 , the lifting mechanism 50 and the magnetizing detection mechanism 60 .

[0061] See also Figure 15-17 When the horizontal magnetizer of the present invention is used to magnetize the rotor, the magnetization method is as follows:

[0062] Move the chuck seat 21 and the abutting seat 31 to a preset distance;

[0063] The lifting mechanism 50 is started; the support bracket 51 of the lifting mechanism 50 is raised between the chuck seat 21 and the abutting seat 31, and the rotor is sent to the support bracket 51 by an external tool. According to the diameter of the rotor, the height of the rotor is finely adjusted so that the centers of the two ends of the rotor are aligned with the chuck seat 21 and the abutting seat 31;

[0064] The abutting seat 31 is started, and the abutting seat 31 slides toward the chuck seat 21, so that the rotor is tightly abutted between the abutting seat 31 and the chuck seat 21, and the support bracket 51 moves horizontally together with the rotor. After one end of the rotor pushes against the chuck seat 21, the chuck seat 21 clamps one end of the rotor;

[0065] The support bracket 51 of the lifting mechanism 50 is lowered, the support bracket 51 is horizontally moved to reset, and the support bracket 51 is lowered to the guide rail 11 below the surface of the machine platform 10;

[0066] The magnetizing mechanism 40 starts, and its magnetizing cylinder 41 moves along the guide rail 11, and moves step by step to magnetize the rotor section by section. After the magnetization is completed, the magnetizing cylinder 41 returns to its original position.

[0067] The magnetization detection mechanism 60 is started, the rotor rotates, and the detection member 61 gradually moves along the axial direction of the rotor on the outer periphery of the rotor to detect the rotor section by section. After the detection is completed, the detection member 61 returns to its original position;

[0068] The support bracket 51 of the lifting mechanism 50 is lifted to support the rotor, and the chuck seat 21 and the abutting seat 31 move in opposite directions respectively to loosen the clamping of the rotor, and the magnetized rotor is removed by an external tool.

[0069] It can be understood that when replacing rotors of different lengths, it further includes adjusting the initial spacing between the chuck seat 21 and the abutment seat 31, and adjusting the position of the lifting mechanism 50 on the guide rail 11. The lifting mechanism 50 moves on the guide rail 11 to achieve support of the support bracket 51 at the center position of the rotor of corresponding length.

[0070] In summary, the horizontal magnetizer of the present invention supports the rotor through the lifting mechanism 50 when the rotor is installed, and the rotor is tightened by the abutting seat in the axial direction. The two ends of the rotor are respectively held between the chuck seat 21 and the abutting seat 31, and the magnetizing cylinder 41 of the magnetizing mechanism 40 is inserted into the rotor and moves step by step to magnetize the rotor section by section. After magnetization, the rotor is driven to rotate by the chuck seat 21, and the detection member 61 of the magnetization detection mechanism 60 moves step by step to perform magnetic flux detection on the rotor section by section. In this way, a long-length rotor can be conveniently magnetized and detected. The horizontal magnetizer of the present invention can realize the magnetization of the rotor when it is placed horizontally, which is beneficial to the placement of the rotor during magnetization and the site layout of the magnetizer, and greatly facilitates the magnetization of a long-length rotor.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
