Description

Technical Field

[0001] The present invention relates to the technical field of motor rotor processing, and in particular to a rotor magnetic processing device and an angle positioning mechanism thereof. Background Art

[0002] During the manufacturing process of the motor rotor, the main section of the rotor needs to be magnetized to make it magnetic, and the end of the rotor needs to be demagnetized after the rotor is magnetized. In this way, it is sent to the corresponding position in the magnetization equipment during magnetization, and sent to the corresponding position in the demagnetization equipment during demagnetization. Whether it is magnetization or demagnetization processing, it is necessary to ensure that the height and direction of the rotor position are accurate to ensure demagnetization efficiency. Figure 1 The rotor shown has a main section 101 and end sections 102 formed at both ends of the main section 101. The end sections 102 are used for assembly and have a smaller diameter than the main section 101. Accordingly, the main section 101 has an end surface 103 formed on the end facing the end. Each end section has a plurality of steps, and the rotor has a plurality of stepped surfaces at both ends. Typically, the step adjacent to the main section 101 has a larger diameter than the other steps and is a first-stage step. Accordingly, a first-stage step is formed facing the other steps at that end. The first-stage step has an assembly slot 104 (in the embodiment of the present invention, a retaining slot) formed on the first-stage step to prevent the rotor from rotating after assembly. Existing rotor magnetic processing devices use a variety of rotor height and orientation positioning mechanisms, including positioning using auxiliary positioning mechanisms and positioning by a fixed manipulator after positioning at a previous station. However, the overall structure, operational convenience, and positioning accuracy can be further improved. Summary of the Invention

[0003] In view of the above, it is necessary for the present invention to provide an angular positioning mechanism for rotor magnetic processing that can simplify the structure and is conducive to ensuring positioning accuracy.

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

[0006] In addition, the present invention provides a rotor magnetic processing device having the angle positioning mechanism.

[0007] A rotor magnetic processing device includes a machine base, a turntable structure and a magnetic processing box. The machine base includes a machine platform and a frame installed on the machine platform. The turntable structure is installed on the machine platform and includes a turntable. Multiple processing stations are arranged around the turntable on the machine platform. The turntable rotates, driving the rotor on the turntable to enter each processing station in sequence. The magnetic processing box is installed on the machine platform and is located at one of the processing stations. The rotor magnetic processing device includes the angle positioning mechanism. The lifting mechanism is installed on the machine platform, which is used to clamp the rotor and lift the rotor up and down in the magnetic processing box. The driving mechanism is installed on the frame, which is used to drive the rotor to rotate until the rotor is clamped by the lifting mechanism.

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

[0009] The present invention is an angle positioning mechanism for rotor magnetic processing. A crimping sensing structure and a landing clamping structure are provided. The crimping sensing structure and the landing clamping structure are jointly installed in the shaft cylinder and integrated through a fixed seat, so that the structure is compact and easy to assemble. The crimping sensing structure detects whether the top end of the shaft cylinder carries the rotor, and the landing clamping structure clamps the rotor and feeds back whether it is clamped in place, thereby realizing precise angular positioning of the rotor during processing. The rotor magnetic processing device with the angle positioning mechanism can quickly position the direction of the rotor through the angle positioning mechanism, and can drive the rotor to rise and fall to the desired processing position through the driving cylinder, thereby greatly improving the rotor magnetic processing efficiency and processing accuracy.

DETAILED DESCRIPTION

[0026] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0027] 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 an angle 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 set around the turntable 20 on the machine table 11. The turntable 21 rotates, driving 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, correspondingly forming a magnetic processing station for performing magnetic processing on the rotor brought in by the turntable 21, such as magnetization or demagnetization. In the figure of this embodiment, two magnetic processing boxes 30 are provided, separated at two processing stations, and the angle positioning mechanism is used to perform angle positioning on the rotor at the station, such as performing angle positioning on the rotor transferred into the magnetic processing station to ensure the efficiency of the rotor magnetic processing. The angle positioning mechanism includes a lifting mechanism 40 and a driving mechanism 60. The lifting mechanism 40 is installed on the machine platform 11, and is used to clamp the rotor and lift the rotor up and down, such as clamping the rotor and lifting it up and down in the magnetic processing box 30. The driving mechanism 60 is installed on the frame 12, and is used to drive the rotor to rotate until the rotor is clamped by the lifting mechanism 40.

[0028] 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.

[0029] See also Figure 3 、 Figure 4 The turntable structure 20 further 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 mounted on the top surface of the machine platform 11, supporting the center of the turntable 21 and driving the turntable 21 to rotate according to the desired angle.

[0030] The tray structure 22 is arranged corresponding to the through hole 211 for carrying and fixing 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 to communicate with the bearing hole 2211. 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 face 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 disengaged from the rotor at the notch 2212, and the tray 221 is no longer supporting the rotor; at this time, the rotor is received on the lifting mechanism 40 and supported by the lifting mechanism 40.

[0031] 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 through-hole 211. The tray 221 is installed on the slide rail 223 and is guided by the slide rail 223 to slide.

[0032] The magnetic processing box 30 is a magnetizing or demagnetizing device having a processing channel that passes through from top to bottom, so that the rotor can be moved up or down 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.

[0033] See also Figure 5 、 Figure 6 The lifting mechanism 40 includes a fixed frame 41, a drive cylinder 42, a lifting plate 43, and a receiving tube structure 44. The fixed frame 41 is fixed to the machine platform 11. Specifically, the fixed frame 41 includes a fixed plate 411 and a plurality of fixed columns 412 erected on the fixed plate 411. The top ends of the fixed columns 412 are fixed to the bottom surface of the table panel of the machine platform 11, so that the fixed plate 411 is fixedly and parallelly installed below the table panel. The drive cylinder 42 is fixedly erected on the fixed plate 411. The cylinder body of the drive cylinder 42 extends upward through the table panel of the machine platform 11. The piston rod of the drive cylinder 42 extends downward through the fixed plate 411 and connects to the lifting plate 43, driving the lifting plate 43 to move up and down. In this embodiment, there are two drive cylinders 42, located at both ends of the fixed plate 411. The piston rods of the two drive cylinders 42 respectively pass through the fixed plate 411 and connect to the two ends of the lifting plate 43. The drive cylinder 42 is preferably a pneumatic cylinder.

[0034] Furthermore, the fixing frame 41 includes guide rods 413 , and a plurality of guide rods 413 are connected to the bottom surface of the fixing plate 411 . The guide rods 413 pass through the lifting plate 43 to guide the lifting plate 43 to move upward and downward, thereby improving the stability of the lifting plate 43 .

[0035] Furthermore, the fixing frame 41 includes a reinforcing plate 414 for inserting and fixing the bottom ends of the plurality of guide rods 413 to prevent the guide rods 413 from moving in the radial direction, thereby improving the stability of the plurality of guide rods 413.

[0036] See also Figure 7 、 Figure 8 The receiving tube structure 44 is installed on the lifting plate 43 and slides together with the lifting plate 43. Specifically, the specific embodiment of the present invention provides a receiving tube structure 44 with a unique structure, so that the entire receiving tube structure 44 has a compact structure, good stability and is easy to assemble, with accurate sensing and ensuring the angle accuracy after receiving the rotor.

[0037] The receiving cylinder structure 44 includes a shaft cylinder 441 and an angle locking assembly 442 installed on the shaft cylinder 441. The shaft cylinder 441 includes a main cylinder section 4411, a base cylinder section 4412, a locking cylinder section 4413 and a gasket 4414. Each cylinder section is formed with a hollow cylinder cavity with two ends open. The cylinder sections of the shaft cylinder 441 are fixed axially. Specifically, adjacent cylinder sections are fixed by screws, and the gasket 4414 is fixed to the top surface of the locking cylinder section 4413 by screws.

[0038] The main barrel section 4411 is a long tube, longer than the machining channel of the magnetic machining box 30. Its bottom end is mounted on the lifting plate 43. The main barrel section 4411 passes through the machining channel of the magnetic machining box 30, and its top end is fixedly connected to the base barrel section 4412. The top surface of the main barrel section 4411 is formed with a first annular body, which allows the base barrel section 4412 to be sleeved therein. The first annular body is provided with a plurality of fixing grooves 401 and a plurality of threaded holes (not shown) for the assembly of the angle positioning assembly 442.

[0039] See also Figure 9A second annular body is integrally formed within the barrel cavity of the base barrel section 4412 and its wall. The second annular body protrudes from the top surface of the base barrel section 4412, and one end of the protrusion can be sleeved within it by the locking barrel section 4413. A bearing ring 402 is formed on the circumference of the central channel of the second annular body for assembly of the angle locking assembly 442, and the bottom surface of the second annular body is at a preset distance from the bottom surface of the base barrel section 4412, correspondingly forming an assembly cavity 403 for assembly of the angle locking assembly 442. Furthermore, a first through-shaft hole 404 and a slideway 406 are provided on the top surface of the second annular body, which are connected to the assembly cavity 403 for assembly of the angle locking assembly 442. Similarly, a plurality of screw holes (not marked in the figure) are provided on the top surface of the second annular body for screwing the base barrel section 4412 to the main barrel section 4411, or for screwing the locking barrel section 4413 to the base barrel section 4412.

[0040] A chute 405 is axially defined on the inner circumference of the locking barrel section 4413, extending through both ends of the locking barrel section 4413. A second through-axis hole is axially defined on the end surface of the locking barrel section 4413, allowing the first through-axis hole 404 to communicate with the second through-axis hole, and the chute 405 to communicate with the slideway 406, after the locking barrel section 4413 is screwed onto the base barrel section 4412.

[0041] Furthermore, an annular flange 407 is formed along the peripheral wall near the top opening of the positioning barrel section 4413, which can be used to correspondingly cooperate with the primary step surface of the rotor. Preferably, the flange 407 is set at a preset distance from the top opening of the positioning barrel section 4413, and will not interfere with the rotor end face abutting against the top surface of the shaft barrel 441.

[0042] Backing ring 4414 is used to cushion the locking barrel section 4413, allowing the end face of the rotor main section to abut against it. A third axial through-hole is defined on the ring surface of backing ring 4414, allowing the third through-hole to communicate with the second through-hole after backing ring 4414 is installed on locking barrel section 4413. As will be appreciated, backing ring 4414 can be selected with a corresponding thickness to accommodate different rotors. A notch 409 is defined on backing ring 4414, corresponding to the chute 405 of locking barrel section 4413, to facilitate installation of the angle locking assembly 442.

[0043] See also Figure 10-13 The angle positioning assembly 442 includes a fixed seat 51, a crimping sensing structure 52, a positioning holding structure 53 and a support shaft seat structure 54. The fixed seat 51 includes a column 511 and a plurality of lugs 512 extending on the side of the column 511. A central through hole and a side through hole are axially provided on the end face of the column 511. The fixed seat 51 is fixedly installed on the top surface of the main barrel section 4411. The plurality of lugs 512 are respectively accommodated in the fixing grooves 401 and locked, so that the fixed seat 51 is correspondingly fixed to the top end of the main barrel section 4411.

[0044] The crimping sensing structure 52 includes a crimping rod 521, a crimping rod reset part 522, a sensing rod 523, a connecting cross block 524 and a crimping sensor 525. The crimping rod 521 can be slidably inserted into the shaft tube 441, passing through the first through-axis hole 404, the second through-axis hole and the third through-axis hole. One end of the crimping rod extends out of the top surface of the shaft tube 441, and the other end is inserted into the assembly cavity 403; the crimping rod reset part 522 is used to push against the crimping rod 521 to reset it. The crimping rod reset part 522 is installed on the base cylinder section 4412, corresponding to the lower end of the crimping rod 521, and a compression spring can be optionally used. The sensing rod 523 is connected to the bottom end of the crimping rod 521 via a connecting cross piece 524. Specifically, one end of the connecting cross piece 524 is connected to the top end of the sensing rod 523, and the other end is connected to the bottom end of the crimping rod 521. The sensing rod 523 passes through the side through-hole of the column 511, extends from the bottom of the main barrel section 4411, and passes through the bottom surface of the lifting plate 43. When the crimping rod 521 moves downward, the sensing rod 523 is driven downward together, and when the crimping rod 521 returns to its original position and rises, the sensing rod 523 returns to its original position and rises together. The crimping sensor 525 is installed on the bottom surface of the lifting plate 43 to sense the sensing rod 523. After the crimping rod 521 is compressed, the lower end of the sensing rod 523 extends to the crimping sensor 525 on the bottom surface of the lifting plate 43, triggering the induction, and determining that the rotor is crimped onto the shaft barrel 441.

[0045] The positioning and holding structure 53 includes a slide 531, a support beam 532, a slide reset member 533, a transmission rod 534, and a positioning sensor 535. The slide 531 is slidably mounted within the slide groove 405. A latching portion 5311 extends from the top of the slide 531 toward the center of the positioning barrel section 4413, allowing it to be snapped into the rotor's positioning groove. The support beam 532 is radially mounted within the assembly cavity 403 of the base barrel section 4412. The support beam 532 is used to support the slide 531. In this embodiment, two slide grooves 405 are formed in opposite directions on the shaft barrel 441, corresponding to two slides 531 mounted at both ends of the support beam 532. The slide reset member 533 is used to provide elasticity to restore the slide 531 after it is compressed. The slide reset member 533 is mounted within the central through hole of the fixed base 51 and elastically supports the support beam 532. The conduction rod 534 is installed in the main tube section 4411, with its top end passing through the center through hole and fixed to the support beam 532, and its bottom end passing through the bottom surface of the main tube section 4411 and out of the bottom surface of the lifting plate 43. When the slide bar 531 moves down, it moves down together, and when the slide bar 531 returns to its original position and rises, it returns to its original position and rises together. The position sensor 535 is installed on the bottom surface of the lifting plate 43 and is used to sense the position of the slide 531. When the rotor is installed on the shaft cylinder 441, the step surface of the rotor's stage will press against the slide 531. The slide 531 moves downward after being pressed, and the rotor is rotated. When the rotor's positioning groove is aligned with the slide's clamping part 5311, the clamping part 5311 will fall into the positioning groove. In this way, the slide 531 moves upward, driving the conduction rod 534 to move upward. The lower end of the conduction rod 534 extends to the position sensor 535 on the bottom surface of the lifting plate 43, triggering the induction, and determining that the rotor is in the angular position corresponding to the required magnetic processing. The cooperation between the positioning groove and the clamping part 5311 can prevent the rotor from rotating further.

[0046] The support shaft seat structure 54 includes a sleeve column 541, a guide bearing 542, a fixed bearing 543, and a locking pin 544. The sleeve column 541 is designed to fit within the axial hole at the center of the rotor's bottom end, supporting the rotor's bottom end and rotating with the rotor as it rotates. The sleeve column 541 comprises a cylindrical body and a tapered portion formed on its outer periphery, dividing the body into an upper and lower section. The upper end is designed to pass through the axial hole at the rotor's bottom end, where its tapered portion abuts the rotor's bottom hole. This creates pressure on the rotor against the sleeve column 541, driving the rotation of the rotor. The lower column section is used to install the guide bearing 542 and the fixed bearing 543, wherein the guide bearing 542 is sleeved on the upper end of the lower column section. Specifically, the guide bearing 542 is sleeved behind the lower column section and installed in the cylindrical cavity of the base cylinder section 4412 and pressed against the load-bearing ring 402, and supported by the load-bearing ring 402. Specifically, the guide bearing 542 is installed in the central channel of the second annular body and supported on the load-bearing ring 402, and the fixed bearing 543 is sleeved on the lower end of the lower column section, located in the cylindrical cavity of the base cylinder section 4412 and below the load-bearing ring 402, and the locking pin 544 is locked to the end face of the lower column section and pressed against the lower end face of the inner ring of the fixed bearing 543, so that the fixed bearing 543 and the guide bearing 542 clamp the load-bearing ring 402, so that the sleeve column 541 is rotatably installed in the base cylinder section 4412, and the installation is stable and easy to assemble. In this embodiment, two guide bearings 542 are provided, and one fixed bearing 543 is provided.

[0047] See also Figure 14 The driving mechanism 60 includes a lifting assembly 61 and a driving assembly 62. The lifting assembly 61 includes a lifting guide frame 611 and a lifting drive 612. The lifting guide frame 611 includes a fixed guide plate and a lifting guide plate. The fixed guide plate is mounted on the frame 12, and the lifting guide plate is mounted on the fixed guide plate so as to be liftable. The lifting drive 612 is used to drive the lifting guide plate to slide. The lifting drive 612 can use a motor screw to drive the lifting guide plate to move up and down. The driving assembly 62 includes a driving motor 621 and a driving shaft 622. The driving motor is mounted on the lifting guide plate. The driving shaft 622 is connected to the output end of the driving motor 621 and is driven to rotate by the driving motor 621.

[0048] After the rotor is installed to the top of the shaft tube 441, the lifting drive member 612 of the driving mechanism 60 drives the lifting guide plate to move downward, so that the driving shaft 622 abuts against the top of the rotor, and then the driving motor 621 drives the driving shaft 622 to rotate, thereby driving the rotor to rotate.

[0049] When the rotor magnetic processing device of the present invention performs magnetic processing on the rotor, the rotor enters the magnetic processing station. When the rotor is positioned at an angle, the driving cylinder 42 of the lifting mechanism 40 first drives the receiving cylinder structure 44 to rise, and the shaft cylinder 441 is sleeved on the lower end of the rotor, so that the top surface of the shaft cylinder 441 is pressed against the end surface of the rotor. At this time, the pressing sensor 525 of the sensing rod 523 extending from the lower end to the bottom surface of the lifting plate 43 triggers the sensing, and determines that the rotor is pressed against the top surface of the shaft cylinder 441. The slide bar 531 of the positioning holding structure 53 is pressed down by the stage of the rotor; then, the lifting driving member 612 of the driving mechanism 60 drives the lifting guide plate to move downward, and the driving shaft 622 abuts against the top end of the rotor. Then, the driving motor 621 drives the driving shaft 622 to rotate, thereby driving the rotor to rotate. When the rotor rotates until its positioning groove is aligned with the slide bar 531, the slide bar 531 slides into the positioning groove. At this time, the angle of the rotor is adjusted to the right position, and the positioning groove prevents the rotor from rotating further.

[0050] Then, the drive cylinder 42 drives the lifting plate 43 downward, and the lifting drive 612 drives the lifting guide plate downward, allowing the rotor to enter the magnetic processing box 30 for magnetic processing. After processing is completed, the drive cylinder 42 cooperates with the lifting drive 612 to lift the rotor to the corresponding position on the turntable 21. The tray structure 22 then receives the rotor, and the lifting mechanism 40 and the driving mechanism 60 are separated from the rotor, completing the magnetic processing of the rotor.

[0051] In summary, the rotor magnetic processing device of the present invention greatly improves the rotor magnetic processing efficiency and processing accuracy by adopting the angle positioning mechanism.

[0052] Specifically, the angle positioning mechanism adopts the lifting mechanism 40, and the lifting mechanism 40 includes the receiving tube structure 44. The receiving tube structure 44 cooperates with the angle clamping component 442 installed on the shaft tube 441 through the shaft tube 441. The shaft tube 441 adopts a multi-tube segment assembly structure. The angle clamping component 442 cooperates with the multi-section tube segment by setting a fixed seat 51, a crimping sensing structure 52, a landing clamping structure 53 and a supporting shaft seat structure 54. The crimping sensing structure 52 detects whether the top end of the shaft tube carries the rotor, and the landing clamping structure 53 is used to clamp the rotor and feedback whether it is clamped in place or not. The crimping sensing structure 52 is coordinated by the crimping rod 521, the crimping rod reset piece 522, the sensing rod 523, the connecting cross piece 524 and the crimping sensor 525. The crimping rod 521 elastically extends from the top end face of the shaft cylinder, and is used to press the crimping rod 521 to move when the rotor is installed at the top end of the shaft cylinder. The crimping sensor 525 correspondingly sends a sensing signal that the crimping is in place. The positioning holding structure is connected by the slide bar 531, the support beam 532, the slide bar reset piece 533, the conductive rod 534. In conjunction with the positioning sensor 535, the sliding bar is axially and elastically installed on the inner wall of the shaft tube, so that when the rotor is installed on the top of the shaft tube, the rotor presses the sliding bar 531 downward, and as the rotor rotates, when the sliding bar 531 is aligned with the rotor's positioning groove, the sliding bar moves up and is positioned in the positioning groove, and the positioning sensor correspondingly sends a sensing signal of positioning.
