Description

Technical Field

[0001] The invention relates to the technical field of motor rotor processing, and in particular to a rotor positioning crimping structure, a rotor positioning mechanism with the crimping structure, and a magnetizing station structure. Background Art

[0002] During the manufacturing process of the motor rotor, it is necessary to magnetize the rotor. The magnetization process is to send the rotor to a magnetization device or a magnetization station for magnetization. Existing magnetization, demagnetization and surface magnetization integrated equipment disclosed in CN202410565961.0 and a processing device for rotor production disclosed in CN202321016114 both use a turntable structure to transfer the rotor to the corresponding magnetization processing station through a turntable. The rotor is magnetized by the corresponding magnetization equipment at the station. During magnetization, it is necessary to ensure that the height and orientation of the rotor are accurate to ensure the demagnetization efficiency. Figure 1 The rotor shown has a main body section 101 and end portions 102 formed at both ends of the main body section 101. The end portions 102 are used for assembly, and their diameter is smaller than that of the main body section 101. Correspondingly, an end surface 103 is formed at one end of the main body section 101 facing the end, and a plurality of steps are formed at each end. Correspondingly, the two ends of the rotor have a plurality of step surfaces, and assembly grooves 104 (used as clamping grooves in the embodiment of the present invention) are formed on the steps, and shaft sleeve holes are opened on both end surfaces of the rotor to facilitate the clamping of the two ends of the rotor by the positioning mechanism. Usually, the rotor positioning mechanism includes a crimping structure located above the rotor and a jacking assembly structure located below the rotor. The two ends of the rotor are clamped by the crimping structure and the jacking assembly structure, and are lifted and lowered synchronously, so as to move the rotor to a height position corresponding to the magnetization processing station, and further, the rotor needs to be rotated to the corresponding orientation position, and the crimping structure of the existing rotor positioning mechanism is mostly hard contact or has a small buffer when contacting with the rotor, which is not conducive to the clamping and installation of the rotor by the positioning mechanism, and the durability of the positioning mechanism. Summary of the invention

[0003] In view of the above, it is necessary for the present invention to provide a crimping structure that can provide greater buffering and facilitates the positioning of the rotor when connecting the rotor.

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

[0005] A crimping structure for positioning a rotor comprises a crimping shaft, an end sleeve, a top cone, an elastic member, a connecting pin and a plurality of latch pins. The bottom end of the crimping shaft is provided with a sleeve hole along the axial direction, correspondingly forming a sleeve part, and a relatively arranged longitudinal sliding hole is provided on the cylinder wall of the sleeve. The end sleeve comprises a sleeve end, the sleeve end is sleeved in the sleeve hole, the upper section of the sleeve end is provided with a pin-through hole along the radial direction, the bottom end of the end sleeve is provided with a receiving hole along the axial direction, and the lower section of the sleeve end is provided with a rotation-limiting hole and a position-limiting hole connected with the receiving hole along the radial direction. An annular groove and a longitudinal groove are provided on the outer circumferential surface of the top cone, the top cone is installed in the receiving hole, the elastic member is compressed between the top cone and the bottom surface of the receiving hole, the latch pin penetrates into the rotation-limiting hole and enters the longitudinal groove to limit the rotation of the top cone, the latch pin penetrates into the position-limiting hole and penetrates into the annular groove to limit the lifting and lowering of the top cone, the connecting pin passes through the pin-through hole of the end sleeve and the two ends of the connecting pin can be slidably accommodated in the relative longitudinal sliding holes along the axial direction.

[0006] In addition, the present invention provides a rotor positioning mechanism with a crimping structure.

[0007] A rotor positioning mechanism includes a pressing mechanism, which includes a lifting assembly, a driving mechanism, and the crimping structure. The lifting assembly includes a guide plate, a sliding plate, and a lifting drive. The sliding plate can be lifted and lowered on the guide plate. The lifting drive is used to drive the sliding plate to slide. The driving mechanism includes a driving motor and a transmission belt. The driving motor is fixedly installed on the sliding plate. The output shaft of the driving motor is connected to the crimping structure through the transmission belt, thereby driving the crimping structure to rotate.

[0008] In addition, the present invention necessarily provides a magnetizing station structure having the rotor positioning mechanism.

[0009] A magnetizing station structure comprises a machine base, a turntable structure and a magnetic processing box. The machine base comprises a machine platform and a frame mounted on the machine platform. The turntable structure is mounted on the machine platform and comprises a turntable. A plurality of processing stations are arranged around the turntable on the machine platform. The turntable rotates to drive a rotor on the turntable to enter each processing station in sequence. The magnetic processing box is mounted on the machine platform and is located at one of the processing stations. The magnetizing station structure comprises the rotor positioning mechanism. A pressing mechanism is mounted on the frame and is used to drive the rotor to rotate until the rotor is positioned by the lifting mechanism and to press the rotor down to a preset height in the magnetic processing box. The lifting mechanism is mounted on the machine platform and is used to lift the rotor and position the rotor that has rotated into position.

[0010] The beneficial effects of the present invention are:

[0011] The crimping structure of the present invention realizes an upward buffering stroke during crimping by setting a longitudinal sliding hole on the crimping shaft, and realizes an elastic connection by setting an elastic member to be compressed between the top cone and the end sleeve, which can further buffer and avoid hard contact, and also improves the durability of the crimped parts. The rotor positioning mechanism with the crimping structure not only has the buffering effect brought by the crimping structure during crimping, but also can accurately realize the height and angle positioning of the rotor during processing through the cooperation of the pressing mechanism and the lifting mechanism. The lifting mechanism is provided with a crimping sensing structure and a direction clamping structure, which are jointly installed in the shaft tube and integrated through the guide seat, so that the structure is compact and easy to assemble. The crimping sensing structure is used to detect whether the top end of the shaft tube carries the rotor, and the direction clamping structure clamps the rotor and feeds back whether it is clamped in place, thereby realizing accurate angular positioning of the rotor during processing. The magnetizing station structure with the rotor positioning mechanism greatly improves the magnetic processing efficiency and processing accuracy of the rotor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 2As shown, an embodiment of the present invention provides a rotor magnetic processing device, including a machine base 10, a turntable structure 20, a magnetic processing box 30 and a rotor positioning mechanism. The machine base 10 includes a machine table 11 and a frame 12 installed on the machine table 11. The turntable structure 20 is installed on the machine table 11 and includes a turntable 21. A plurality of processing stations can be arranged around the turntable 20 on the machine table 11. The turntable 21 rotates to drive the rotor on the turntable 21 to enter each processing station in turn. The magnetic processing box 30 is installed on the machine table 11 and is located at one of the processing stations, and is correspondingly formed as a magnetic processing station for performing magnetic processing on the rotor brought in by the turntable 21, such as magnetizing or demagnetizing. In the figure of this embodiment, two magnetic processing boxes 30 are provided, which are separated at two processing stations. The rotor positioning mechanism is used to position the rotor at the station, such as angularly positioning the rotor transferred into the magnetic processing station and lifting it to a corresponding height position to ensure the efficiency of the rotor magnetic processing. The rotor positioning mechanism includes a pressing mechanism 40 and a lifting mechanism 50. The pressing mechanism 40 is mounted on the frame 12 and is used to drive the rotor to rotate until the rotor is locked by the lifting mechanism 50, and to press the rotor down to a preset height. The lifting mechanism 50 is mounted on the machine platform 11 and is used to lift the rotor and lock the rotor that has rotated into place, ensure the orientation of the rotor, and move downward in cooperation with the pressing mechanism 40 to provide constant support for the rotor.

[0032] The turntable 21 is rotatably mounted on the top surface of the machine platform 11 and has a preset height. A plurality of through holes 211 are formed on the top surface of the turntable 21 adjacent to the outer circumference along a circular line. The number of the through holes 211 corresponds to the number of set processing stations.

[0033] Combined with reference Figure 3 , Figure 4 The turntable structure 20 includes a plurality of tray structures 22 disposed on the turntable 21, and a turntable drive mechanism (not shown) disposed on the bottom surface of the turntable 21 for driving the turntable 21 to rotate. The turntable drive mechanism is installed on the top surface of the machine table 11, supports the center of the turntable 21, and can drive the turntable 21 to rotate according to the required angle.

[0034] The tray structure 22 is arranged corresponding to the through hole 211, and is used to carry and fix the rotor; the tray structure 22 includes a tray 221 and a pusher 222, the tray 221 is slidably arranged on the top surface of the turntable 21, the tray 221 is connected to one end of the pusher 222, and is pushed to slide on the top surface of the turntable 21 by the pusher 222, a bearing hole 2211 is formed in the center of the tray 221, and a notch 2212 is formed on the outer periphery of the tray 221 and is connected to the bearing hole 2211, and when the tray 221 slides to the processing station, the bearing hole 221 1 is aligned with the through hole 211, and can receive the rotor, that is, the end of the rotor is inserted into the bearing hole 2211, so that the end surface of the main section of the rotor is pressed against the disk surface of the tray 221 surrounding the bearing hole 2211, and the tray 221 supports the main section of the rotor; when the tray 221 slides away from the processing station, the bearing hole 2211 and the through hole 211 are staggered, and the tray 221 is separated from the rotor at the notch 2212, and the tray 221 is separated from the support for the rotor; at this time, the rotor is received on the lifting mechanism 50 and supported by the lifting mechanism 50.

[0035] Preferably, the pusher 222 is a cylinder, and the tray 221 is connected to the piston end of the cylinder. Further, the tray structure 22 includes a slide rail 223, which is installed on the top surface of the turntable 21 and extends to the corresponding perforation 211. The tray 221 is installed on the slide rail 223 and guided to slide by the slide rail 223.

[0036] The magnetic processing box 30 is a magnetizing or demagnetizing device, and has a processing channel that runs through from top to bottom, so that the rotor can rise or fall to a preset position in the processing channel to perform magnetic processing on the rotor. The magnetic processing box 30 can be purchased directly, and its structure will not be described here.

[0037] See also Figure 5 , Figure 6 The pressing mechanism 40 includes a lifting assembly 41, a driving mechanism 42, and a crimping structure 43. The lifting assembly 41 includes a guide plate 411, a sliding plate 412, and a lifting drive 413. The guide plate 411 is installed on the frame 12, and the sliding plate 412 can be lifted and lowered on the guide plate 411. The lifting drive 413 is used to drive the sliding plate 412 to slide. The lifting drive 413 can use a motor screw rod to drive the sliding plate 412 to lift and lower. It can be understood that a guide groove and guide rail matching structure is provided between the guide plate 411 and the sliding plate 412. The driving mechanism 42 includes a driving motor 421 and a transmission belt 422. The driving motor 421 is fixedly installed on the sliding plate 412. The output shaft of the driving motor 421 is connected to the crimping structure 43 through the transmission belt 422, thereby driving the crimping structure 43 to rotate.

[0038] After the rotor is installed to the top of the lifting mechanism 50, the lifting drive member 413 of the pressing mechanism 40 drives the sliding plate 412 to move downward, so that the crimping structure 43 presses against the top of the rotor, and then drives the motor 421 to drive the crimping structure 43 to rotate, thereby driving the rotor to rotate.

[0039] Furthermore, the sliding plate 412 includes a vertical sliding plate and a loading plate vertically connected to the vertical sliding plate, and the driving mechanism 42 is installed on the loading plate.

[0040] See also Figure 7-Figure 9 The crimping structure 43 includes a crimping shaft 431, an end sleeve 432, a top cone 433, an elastic member 434, a connecting pin 435, a locking pin 436 and a plurality of latches 437. A sleeve hole (not marked in the figure) is axially provided at the bottom end of the crimping shaft 431, which is correspondingly formed into a sleeve portion. Two groups of longitudinal sliding holes 4311 are provided on the wall of the sleeve portion. Each group of longitudinal sliding holes 4311 is two and arranged oppositely. Specifically, longitudinal sliding holes are arranged oppositely on the front and rear sides of the sleeve wall, and longitudinal sliding holes are arranged oppositely on the left and right sides of the sleeve wall. Each longitudinal sliding hole 4311 extends a preset length along the axial direction, and the longitudinal sliding hole 4311 is connected to the sleeve hole. The four longitudinal sliding holes 4311 are distributed in four directions (front, rear, left and right) of the circumference of the sleeve portion.

[0041] The end sleeve 432 is in the shape of a convex column, with its top end closed and the bottom end open. Specifically, the end sleeve 432 includes a supporting end and a sleeve end, the sleeve end is sleeved in the sleeve hole, and the supporting end is supported at the port of the sleeve portion. The upper section of the sleeve end is radially provided with a pin hole 4321 and a lock pin hole 4322, the bottom end surface of the end sleeve 432 is axially provided with a receiving hole, and the lower section of the sleeve end is radially provided with a rotation limiting hole 4323 and a position limiting hole 4324 connected with the receiving hole. The upper end of the top cone 433 is a column, and the lower end is a cone. A mounting hole is provided on the top surface of the top cone 433, and an annular groove 4331 is provided on the outer circumference of the top cone 433. The annular groove 4331 surrounds the entire outer circumference, and the annular groove 4331 is provided with a preset groove width; a longitudinal groove 4332 is also provided on the outer circumference of the top cone 433, and the longitudinal groove 4332 extends along the axial direction.

[0042] During assembly, the elastic member 434 is installed in the installation hole on the top surface of the top cone 433, and the top cone 433 is installed in the receiving hole of the end sleeve 432, so that the elastic member 434 is compressed between the top cone 433 and the bottom of the receiving hole, and the latch 437 penetrates the rotation limiting hole 4324 and enters the longitudinal groove 4332 to limit the rotation of the top cone 433, and the latch 437 penetrates the limiting hole 4324 and the annular groove 4331 to prevent the top cone 433 from falling out of the end sleeve 432 and to limit the rotation of the top cone 433. The lifting stroke is limited, the sleeve end of the end sleeve 432 is sleeved in the sleeve hole of the crimping shaft 431, the connecting pin 435 passes through a group of longitudinal sliding holes 4311 and passes through the pin hole 4321 of the end sleeve 432, and the two ends of the connecting pin 435 can be slidably accommodated in the longitudinal sliding holes 4311, and two locking pins 436 are provided to pass through the locking pin holes 4322 from another group of two longitudinal sliding holes 4311 to lock the connecting pin 435 to prevent the connecting pin 435 from slipping out of the pin hole 4321.

[0043] Furthermore, a locking ring groove is provided in the middle of the connecting pin 435 for one end of the locking pin 436 to be inserted into.

[0044] Thus, the end sleeve 432 can have a certain axial sliding stroke relative to the crimping shaft 431, i.e., the axial length of the longitudinal sliding hole 4311. In addition, the top cone 433 elastically presses downward (the upper end surface of the annular groove 4331 presses against the connecting pin 435) and the top cone 433 has an upward compression stroke, i.e., corresponding to the groove width of the annular groove 4331.

[0045] Furthermore, the crimping structure 43 further includes an outer cylinder 438 and a bearing installed in the outer cylinder 438 . The outer cylinder is sleeved on the outer periphery of the crimping shaft 431 through the bearing.

[0046] Furthermore, the top end of the outer cylinder 438 is fixedly connected to the loading plate, the top end of the crimping shaft 431 passes through the top end of the outer cylinder and protrudes on the loading plate, and the transmission belt 422 is sleeved on the protruding end of the crimping shaft 431 .

[0047] See also Fig.10When the crimping structure 43 crimps the rotor, the upper end of the rotor is inserted into the receiving hole of the end sleeve 432, and the sleeve hole at the end of the rotor is inserted into the top cone 433 and abuts against the conical surface of the top cone 433, applying a push-up holding force to the top cone 433. At this time, the end sleeve 432 will slide upward relative to the crimping shaft 431 by a preset distance, that is, the length of the longitudinal sliding hole 4311 in the axial direction, to perform crimping buffering. Then, as the crimping structure 43 is further pressed down, the top cone 433 will slide upward relative to the end sleeve 432, and the spring is compressed until the lower end surface of the annular groove 4331 of the top cone 433 abuts against the connecting pin 435. At this time, if the crimping structure 43 moves down further, it will drive the rotor to move down together until it moves to the height position required by the rotor for magnetic processing. It can be seen from the above crimping process that when the crimping structure 43 crimps the rotor, the sliding buffer of the end sleeve 432 and the compression buffer of the spring release the rigid contact during crimping, avoid hard contact, and improve the durability of the crimped components. It can also ensure that sufficient holding force is provided on the top surface of the rotor to drive the rotor to rotate when the crimping shaft 431 rotates.

[0048] See also Fig.11 The lifting mechanism 50 includes a fixed frame 51, a driving cylinder 52, a lifting plate 53 and a receiving tube structure 54. The fixed frame 51 is fixedly connected to the machine 11. Specifically, the fixed frame 51 includes a fixed plate 511 and a plurality of fixed columns 512 erected on the fixed plate 511. The top of the fixed column 512 is fixedly connected to the bottom surface of the table panel of the machine 11, so that the fixed plate 511 is fixedly and parallelly installed below the table panel. The driving cylinder 52 is fixedly erected on the fixed plate 511. The cylinder body of the driving cylinder 52 passes through the table panel of the machine 11 upward. The piston rod of the driving cylinder 52 extends downward through the fixed plate 511 and connects to the lifting plate 53, driving the lifting plate 53 to rise and fall. In this embodiment, there are two driving cylinders 52, which are separated at both ends of the fixed plate 511. The piston rods of the two driving cylinders 52 pass through the fixed plate 511 and are connected to the two ends of the lifting plate 53. The driving cylinder 52 is preferably a cylinder.

[0049] Furthermore, the fixing frame 51 includes guide rods 513 , and a plurality of guide rods 513 are connected to the bottom surface of the fixing plate 511 . The guide rods 513 pass through the lifting plate 53 to guide the lifting of the lifting plate 53 and improve the lifting stability of the lifting plate 53 .

[0050] Furthermore, the fixing frame 51 includes a reinforcing plate 514 for inserting and fixing the bottom ends of the plurality of guide rods 513 to prevent the guide rods 513 from moving in the radial direction, thereby improving the stability of the plurality of guide rods 513 .

[0051] See also Figure 11-Figure 16The receiving cylinder structure 54 is installed on the lifting plate 53 and is lifted and lowered together with the lifting plate 53. The receiving cylinder structure 54 includes a shaft cylinder 55, a guide seat 56, a crimping induction structure, a directional positioning structure and a top support assembly 59. The shaft cylinder 55 is composed of multiple cylinder sections to facilitate processing and assembly of various components. Each cylinder section is fixed in the axial direction. Specifically, adjacent cylinder sections are fixed by screws, and a section in the cylinder channel of the shaft cylinder 55 is formed as an assembly cavity. Furthermore, a gasket 552 can be set at the top of the shaft cylinder 55 to cushion the receiving rotor.

[0052] The guide seat 56 includes a column 561 and a plurality of lugs 562 extending from the periphery of the column 561 . The guide seat 56 is fixedly installed in the assembly cavity of the shaft cylinder 55 . The plurality of lugs 562 are correspondingly locked on the cylinder wall of the shaft cylinder 55 .

[0053] The crimping sensing structure includes a crimping rod 571, a crimping rod reset member 572, a sensing rod 573, a connecting cross block 574 and a crimping sensor 575. The crimping rod 571 can be slidably sleeved on the shaft tube 55, one end of which extends out on the top surface of the shaft tube 55, and the other end is arranged in the assembly cavity; the crimping rod reset member 572 is used to press against the crimping rod 571 to reset, and the crimping rod reset member 572 is installed in the assembly cavity, corresponding to the lower end of the crimping rod 571, and a compression spring can be selected. The sensing rod 573 can slidably pass through the guide seat 56, which passes through the bottom of the shaft tube 55 and extends out of the bottom surface of the lifting plate 53. One end of the connecting cross block 574 is connected to the top of the sensing rod 573, and the other end is connected to the bottom of the crimping rod 571, so as to drive the sensing rod 573 to move down together when the crimping rod 571 moves down, and drive the sensing rod 573 to reset and rise together when the crimping rod 571 resets and rises. The crimping sensor 575 is installed on the bottom surface of the lifting plate 53 and is used to sense the sensing rod 573. After the crimping rod 571 is compressed, the lower end of the sensing rod 573 extends to the crimping sensor 575 on the bottom surface of the lifting plate 53 to trigger the induction, thereby determining that the rotor is crimped onto the shaft tube 55.

[0054] The positioning structure includes a slide bar 581, a support beam 582, a slide bar reset member 583, a transmission rod 584 and a drop position sensor 585. The slide bar 581 can be slidably installed in the shaft tube along the axial direction, close to the barrel wall of the shaft tube. It can be understood that a slide groove can also be provided on the barrel wall to match the slide bar. The top of the slide bar 581 is adjacent to the top opening of the shaft tube. The support beam 582 is radially installed in the assembly cavity. The support beam 582 is used to support the slide bar 581. In this embodiment, two slide grooves are relatively opened on the shaft tube 55, and correspondingly, there are two slide bars 581, which are installed at both ends of the support beam 582. The slide bar reset member 583 is used to provide elasticity for the slide bar 581 to reset after being compressed. The slide bar reset member 583 is installed on the guide seat 56, and it elastically supports the support beam 582. The top of the transmission rod 584 passes through the guide seat 56 and is fixedly connected to the support beam 582, and the bottom of the transmission rod 584 passes through the shaft tube 55 and extends to the bottom surface of the lifting plate 53. When the slide bar 581 moves down, it drives the transmission rod 584 to move down together, and when the slide bar 581 is reset and raised, it drives the transmission rod 584 to reset and rise together. The drop position sensor 585 is installed on the bottom surface of the lifting plate 53 to sense the drop position of the slide bar 581. When the rotor is installed on the shaft tube 55, the step surface of the rotor stage presses against the slide bar 581. The slide bar 581 moves down after being pressed, and the rotor rotates. When the rotor's positioning groove is aligned with the slide bar 581, the slide bar 581 will fall into the positioning groove. At this time, the slide bar 581 moves up, driving the transmission rod 584 to move up and triggering the drop position sensor 585, so that it can be determined that the rotor is in the angle position corresponding to the required magnetic processing, and the cooperation between the positioning groove and the slide bar 581 can prevent the rotor from rotating further.

[0055] The top support assembly 59 includes a sleeve column 591 and a plurality of guide bearings 592. The sleeve column 591 is used to be inserted into the shaft hole at the center of the bottom end of the rotor to support the bottom end of the rotor and rotate together with the rotor when the rotor rotates. The sleeve column 591 includes a column body and a tapered portion formed on the outer periphery of the column body, and the column body is divided into an upper column section and a lower column section. The upper column end is used to be inserted into the shaft hole at the bottom end of the rotor, and its tapered portion abuts against the shaft hole at the bottom end of the rotor, that is, the rotor has a pressure abutting against the sleeve column 591, which can drive the sleeve column 591 to rotate when the rotor rotates. The guide bearing 592 is sleeved on the lower column section, and the outer ring of the guide bearing 592 is fixed by the barrel wall of the shaft barrel, so that it can rotate relative to the barrel wall through the sleeve column 591.

[0056] Specifically in this embodiment, a load-bearing edge along the circumference is formed inside the shaft cylinder 55, and a plurality of guide bearings 592 are sleeved on the upper end section of the lower column section and loaded on the load-bearing edge. A plurality of guide bearings 592 are sleeved on the lower end of the lower column section, and then pins are provided to lock them to the bottom end surface of the sleeve column 591, and the pins are pressed against the inner ring end surface of the guide bearing 592, that is, the guide bearing 592 is locked on both sides of the load-bearing edge, so that a plurality of guide bearings 592 are fixedly installed in the shaft cylinder 55, which can provide axial support force for the sleeve column 591 and realize the rotation of the sleeve column 591 relative to the shaft cylinder.

[0057] When the rotor magnetic processing device of the present invention performs magnetic processing on the rotor, the rotor is transferred to the magnetic processing station of the rotor magnetic processing device, and the rotor is supported and the angle of the rotor is positioned. First, the driving cylinder 52 of the lifting mechanism 50 drives the receiving cylinder structure 54 to rise, and the shaft cylinder 55 is sleeved on the lower end of the rotor, so that the top surface of the shaft cylinder 55 is pressed against the end surface of the rotor. At this time, the pressing sensor 575 whose lower end of the sensing rod 573 extends to the bottom surface of the lifting plate 53 triggers the induction, and determines that the rotor is pressed against the top surface of the shaft cylinder 55, and the slide bar 581 toward the clamping structure is pressed against the stage of the rotor and slides down; then, the lifting driving member 413 of the pressing mechanism 40 drives the sliding plate 412 to move downward, and the pressing structure 43 is pressed against the top of the rotor, and then the motor 421 is driven to drive the pressing shaft 431 to rotate, thereby driving the rotor to rotate, and when the rotor rotates to the position of its clamping groove and the slide bar 581, the slide bar 581 slides into the clamping groove, and at this time, the angle of the rotor is adjusted to the right position, and the clamping groove prevents the rotor from rotating further.

[0058] As the lifting drive 413 drives the sliding plate 412 to move downward, the crimping structure 43 is further moved downward, and the rotor is moved downward together. The driving cylinder 52 provides a constant supporting force to cooperate with the downward movement of the rotor, so that the rotor enters the magnetic processing box 30 for magnetic processing. After the processing is completed, the lifting drive 413 drives the sliding plate 412 to rise, and the driving cylinder 52 drives the lifting plate 53 to rise, and the rotor rises to the corresponding position on the turntable 21. The tray structure 22 receives the rotor, and then the lifting mechanism 50 is raised, and the pressing mechanism 40 moves downward and separates from the rotor, completing the magnetic processing of the rotor.

[0059] In summary, the rotor magnetic processing device of the present invention adopts the crimping structure 43. When pressed against the rotor, it has a buffer stroke formed by the longitudinal sliding hole and the elastic member is compressed between the top cone and the end sleeve, which avoids hard contact during crimping and improves the durability of the crimped parts. After pressing against the rotor, it provides elastic pressure to the rotor, and when the rotor slides down in alignment, it always maintains the downward pressure on the rotor to achieve stable pressing of the rotor, which is conducive to the precise positioning of the rotor during magnetic processing. The rotor positioning mechanism with the crimping structure 43 not only has the effect brought by the crimping structure 43, but also can accurately realize the height and angle positioning of the rotor during processing through the cooperation of the pressing mechanism 40 and the lifting mechanism 50. The magnetizing station structure with the rotor positioning mechanism greatly improves the rotor magnetic processing efficiency and processing accuracy.

[0060] The above-described embodiments only express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. 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.
