Description

[Technical Field]

[0001] This utility model belongs to the field of motor rotor press-fitting technology, and in particular relates to a clamping and positioning module and press-fitting mechanism compatible with discs and end plates. [Background Technology]

[0002] In the rotor manufacturing process, multiple magnet blocks need to be pressed into the rotor shaft to form a permanent magnet rotor. End plates are also provided at both ends of the multiple magnet blocks to restrict their axial position on the rotor shaft. Existing patent CN119995280B discloses a rotor pressing device with automatically adjustable angles, which includes a rotary positioning assembly, a pressing assembly above the rotary positioning assembly, and a clamping positioning assembly below the pressing assembly. The rotary positioning assembly is used to fix the rotor shaft and drive it to rotate. The clamping positioning assembly is used to clamp and fix the end plates or magnet blocks. The pressing assembly is used to press the end plates or magnet blocks from the clamping positioning assembly onto the rotor shaft on the rotary positioning assembly. In this device, the alignment and positioning of the end plates and magnet blocks rely solely on a pair of grippers, resulting in poor alignment accuracy. Furthermore, there is no error-proofing design for the end plates and magnet blocks, posing a risk that operators may incorrectly press the end plates and magnet blocks in the correct order.

[0003] Therefore, it is necessary to provide a new clamping and positioning module and pressing mechanism compatible with discs and end plates to solve the above-mentioned technical problems. [Utility Model Content]

[0004] One of the main objectives of this utility model is to provide a clamping and positioning module compatible with discs and end plates, which can clamp, center, position, detect errors, and press-fit two types of discs and end plates with different structural features, thereby improving the pressing accuracy and reliability of pressing the end plates and discs onto the rotor shaft.

[0010] An end plate angle positioning rod is installed in the mounting base in a telescopic manner to position the end plate at an angle and is squeezed into a retracted state when the disc is placed in the limiting storage slot.

[0011] The locking assembly includes a first limiting lock rod and a second limiting lock rod that are horizontally slidably disposed within the mounting base and move synchronously. The first limiting lock rod locks and unlocks the extension and retraction of the centering clamping rod through horizontal movement. The second limiting lock rod locks and unlocks the extension and retraction of the end plate angle positioning rod through horizontal movement. When the first limiting lock rod and the second limiting lock rod extend synchronously, the centering clamping rod is locked and remains extended, while the end plate angle positioning rod is unlocked and can extend and retract freely up and down. When the first limiting lock rod and the second limiting lock rod retract synchronously, the end plate angle positioning rod is locked and remains extended, while the centering clamping rod is unlocked and can extend and retract freely up and down.

[0012] Furthermore, the mounting base includes a disc body, a central support platform disposed on the disc body, and a first annular enclosure disposed on the disc body and surrounding the central support platform; an annular mounting groove is formed between the first annular enclosure and the central support platform, the rotating ring is rotatably mounted in the annular mounting groove, and the limiting seat is fixed on the central support platform.

[0013] Furthermore, the mounting base is provided with a first sliding groove; the first sliding groove is radially arranged, with one end passing through the annular mounting groove and the other end extending into the central support platform; the disc clamping assembly is slidably arranged in the first sliding groove, and is driven by the rotating ring to move radially within the first sliding groove to center and clamp the disc.

[0016] Furthermore, the annular body of the rotating ring is provided with a plurality of annularly distributed second drive guide grooves for driving the disc clamping assembly to move; the disc clamping assembly includes a slider radially slidably disposed on the mounting base and a second drive roller disposed on the slider and cooperating with the second drive guide groove for transmission; the centering clamping rod is slidably disposed on the slider and extends upward into the limiting storage groove.

[0019] Furthermore, it also includes a second detection component to detect whether the limiting locking rod in the locking component has extended to the correct position and whether it has retracted to the correct position. The second detection component includes a mounting plate fixedly connected to one end of the first and second limiting locking rods, a sensing protrusion disposed on the mounting plate, and a second sensor and a third sensor fixedly disposed relative to the mounting base for sensing the position of the sensing protrusion. When the second sensor senses the sensing protrusion, it determines that the limiting locking rod has extended to the correct position; when the third sensor senses the sensing protrusion, it determines that the limiting locking rod has retracted to the correct position.

[0020] Furthermore, the mounting base is provided with a fourth sliding groove, and the angle limiting rod is slidably disposed in the fourth sliding groove and extends upward into the limiting storage groove; the fourth sliding groove is provided with a third elastic element that holds the angle limiting rod upward to keep it in an extended state; a vertical angle recognition groove is provided on the outer peripheral surface of the end plate; when the end plate is placed into the limiting storage groove, the angle limiting rod extends into the angle recognition groove to position the end plate at an angle; when the second limiting locking rod retracts, its body part blocks the angle limiting rod from below, preventing the angle limiting rod from retracting and thus locking the extended state of the angle limiting rod.

[0025] Furthermore, it also includes several guide rods, with the first support plate slidably mounted on the guide rods, and a second support plate movably mounted on the guide rods. The second support plate is freely resting on the first support plate, and a centering assembly for positioning the rotor shaft is provided on the second support plate. The centering assembly includes a centering top rod rotatably mounted on the second support plate. The mounting base is provided with a central circular hole that avoids the centering top rod from intersecting with the rotor shaft.

[0026] Compared with existing technologies, the advantages of this utility model's clamping and positioning module and pressing mechanism that is compatible with both discs and end plates are: it can clamp, center, position, perform error-proof detection, and press-fit two types of discs and end plates with different structural features, thereby improving the pressing accuracy and reliability of pressing the end plates and discs onto the rotor shaft. Specifically:

[0027] (1) By setting up an end plate clamping assembly, multiple clamping blocks distributed in a ring are used to clamp the outer peripheral surface of the end plate, which realizes the centering clamping requirements of the end plate and improves the center position accuracy of the end plate before pressing. The clamping range of the clamping blocks is just enough to clamp the end plate without clamping the disc, which effectively avoids the risk of damage to the outer peripheral surface of the disc and ensures the quality of the disc.

[0028] (2) By setting the end plate angle positioning rod, the placement angle of the end plate can be accurately positioned to ensure the assembly accuracy of the end plate; in addition, the end plate angle positioning rod is set as an up-and-down elastic movable structure to avoid the disc body when the disc is placed in the limiting seat.

[0029] (3) By setting up a disc clamping assembly, the centering clamping rod is inserted into the corresponding positioning clamping hole of the disc to center and clamp the disc, which improves the center position accuracy of the disc and ensures the assembly accuracy of the disc; in addition, the centering clamping rod in the disc clamping assembly is set to a vertically movable structure, which avoids the end plate body when the end plate is placed in the limiting seat.

[0030] (4) The switching drive of the end plate clamping assembly clamping and opening action, and the switching drive of the disc clamping assembly positioning working state and initial state are both integrated on a rotating ring. The rotational motion of the rotating ring is used to drive the middle clamping assembly and the disc clamping assembly. The design structure is ingenious and saves space.

[0031] (5) Through the structural design of the locking component, the first limit locking rod and the second limit locking rod move horizontally in a synchronized manner;

[0032] When the two limit locking rods extend simultaneously, only the first limit locking rod has a locking function. It extends under the centering clamping rod and keeps the centering clamping rod in the extended state so that it cannot retract, thus ensuring the positioning function of the centering clamping rod for the disc insertion angle. The second limit locking rod is in the unlocked state, and the end plate angle positioning rod can extend and retract freely up and down. Therefore, when the disc is inserted, it will not interfere with the disc body.

[0033] When both limit locking rods retract synchronously, only the second limit locking rod has a locking function. Its body blocks the end plate angle positioning rod below, keeping the end plate angle positioning rod in the extended state and preventing it from retracting. This ensures the positioning function of the end plate angle positioning rod for the end plate placement angle. Meanwhile, the first limit locking rod is in the unlocked state, and the centering clamping rod can extend and retract freely up and down. Therefore, when the end plate is placed, it will not interfere with the end plate body.

[0034] In addition, the end plate angle positioning rod and the centering clamping rod respectively realize the foolproof detection of the end plate and the disc;

[0035] (6) By setting the first detection component, at least three sensing probes are used to form a surface, ensuring that the disc and end plate are placed horizontally and vertically into the limiting storage slot, avoiding the disc and end plate being placed at an angle, which would cause pressing failure, and ensuring the pressing quality of the disc and end plate and the reliability of the pressing process.

[0036] (7) By setting a second detection component, the limit locking rod in the locking component is detected to extend or retract in place, ensuring that the locking function of the locking component is effective and reliable, preventing the locking function from failing due to manual pushing or pulling of the limit locking rod, and losing the effective guarantee of the respective functions of the end plate angle positioning rod and the centering clamping rod.

Detailed Implementation Methods

[0059] Example 1:

[0060] Please refer to Figures 1-13This embodiment is a press-fitting mechanism 100 compatible with motor rotor discs and end plates. It is used to apply downward pressure to the discs 200 and end plates 300 when multiple discs 200 and two end plates 300 are assembled onto the same rotor shaft 400. It includes a bracket 1, a first drive member 2 and a second drive member 5 fixed on the bracket 1, a first support plate 3 driven by the first drive member 2 to move up and down, a clamping and positioning module 4 disposed on the first support plate 3, a second support plate 6 driven by the second drive member 5 to move up and down and located above the first support plate 3, and a centering component 7 disposed on the second support plate 6 to position the rotor shaft 400.

[0061] This embodiment is applied to a rotor structure assembly production line. The rotor structure includes a rotor shaft 400, several discs 200 (each disc 200 is composed of several thin sheets stacked together, the material of which is determined according to the material of the motor rotor, such as silicon steel sheet, iron-cobalt alloy, etc.) mounted on the rotor shaft 400, and end plates 300. Multiple discs 200 are stacked sequentially to form a disc module. Two end plates 300 are respectively located at the axial ends of the disc module. During the rotor structure assembly process, the discs 200 are pressed onto the rotor shaft, and the end plates 300 are also pressed onto the rotor shaft 400. To enable the pressing operation of the discs 200 and end plates 300 to be completed at the same workstation, improving production efficiency and assembly accuracy, this embodiment optimizes the structure of the clamping and positioning module 4. This optimizes the clamping, centering, and angle error prevention requirements of the two different structural features of the discs 200 and end plates 300, thereby achieving the pressing of both structures. Specifically:

[0062] The clamping and positioning module 4 includes a mounting base 41 fixed on the first support plate 3, a limiting seat 42 fixed on the mounting base 41, a rotating ring 43 rotatably disposed around the limiting seat 42, an end plate clamping assembly 44 driven by the rotating ring 43 to perform centering clamping or releasing operations on the disc 200 on the limiting seat 42, a disc clamping assembly 45 driven by the rotating ring 43 to center clamp the disc 200 on the limiting seat 42, an end plate angle positioning assembly 410 for angle positioning of the end plate 300 on the limiting seat 42, a first detection assembly 46 for detecting whether the disc 200 or the end plate 300 is correctly placed in the limiting seat 42, a locking assembly 47 for locking and unlocking the functions of the end plate angle positioning assembly 410 and the disc clamping assembly 45, a second detection assembly 420 for detecting whether the locking and unlocking functions of the locking assembly 47 are reliable and effective, and a rotation drive assembly 48 for driving the rotating ring 43 to rotate.

[0063] Mounting base 41 includes a disc body portion 411, a central support platform 412 disposed on the disc body portion 411, and a first annular barrier 413 disposed on the disc body portion 411 and surrounding the central support platform 412. An annular mounting groove 414 is formed between the first annular barrier 413 and the central support platform 412. A rotating ring 43 is rotatably mounted in the annular mounting groove 414, and a limiting seat 42 is fixed on the central support platform 412. The annular mounting groove 414 provides motion guidance for the rotation of the rotating ring 43.

[0064] To limit the top of the rotating ring 43, an annular top cover 49 is fixedly installed on the mounting base 41. The annular top cover 49 covers the annular mounting groove 414 to seal the annular mounting groove 414, thereby limiting the top of the rotating ring 43 located in the annular mounting groove 414. The top of the first annular enclosure 413 is provided with a plurality of first threaded holes 4131, and the annular top cover 49 is locked onto the top of the first annular enclosure 413 by screws.

[0065] In this embodiment, the mounting base 41 is provided with a pair of first sliding grooves 415 and a central circular hole 416; the pair of first sliding grooves 415 are arranged radially opposite each other, with one end passing through the annular mounting groove 414 and the other end extending into the central support platform 412, or one end passing through the annular mounting groove 414 and the other end passing through the central support platform 412; the central circular hole 416 passes through the central support platform 412 upwards at one end and the disk body part 411 downwards at the other end, on the one hand avoiding the centering component 7 from passing through, and on the other hand avoiding the rotor shaft 400.

[0066] In other embodiments, depending on the structural features of the disc 200, the number of first grooves 415 may also be set to other quantities, such as three or four or more; all the first grooves 415 are radially arranged and distributed in a ring around the central circular hole 416.

[0067] The disc clamping assembly 45 is slidably disposed in the first slide groove 415 and is driven by the rotating ring 43 to move radially within the first slide groove 415 to achieve centering and clamping of the disc 200. The first slide groove 415 provides a guiding and limiting function for the radial sliding of the disc clamping assembly 45. The central circular hole 416 is used to avoid the aforementioned rotor shaft.

[0068] The limiting seat 42 includes a disc base 421 and a second annular barrier 422 extending upward from the circumference of the disc base 421. The second annular barrier 422 has a limiting and receiving groove 423 that conforms to the outer periphery of the disc 200 and the end plate 300. A plurality of second threaded holes 4121 are provided on the central support platform 412, and the disc base 421 sits on the central support platform 412 and is locked in place by screws.

[0069] The rotating ring 43 has several annularly distributed first drive guide grooves 431 for driving the end plate clamping assembly 44 and second drive guide grooves 432 for driving the disc clamping assembly 45. In this embodiment, three end plate clamping assemblies 44 are provided, and they are annularly distributed around the limiting and receiving groove 421 at equal angles. In other embodiments, four or more end plate clamping assemblies 44 may be provided. In this embodiment, two disc clamping assemblies 45 are provided, and they are symmetrically arranged within the limiting and receiving groove 421. In other embodiments, three, four or more disc clamping assemblies 45 may be provided, and they are annularly distributed within the limiting and receiving groove 421.

[0070] The end plate clamping assembly 44 includes a clamping block 441 and a first transmission roller 442 disposed on the clamping block 441 and engaging with the first drive guide groove 431 for transmission. The clamping block 441 includes a horizontal block 4411 and a vertical block 4412 disposed at one end of the horizontal block 4411 and in a standing position. The horizontal block 4411 rests on the annular body of the rotating ring 43. The first transmission roller 442 is mounted on the lower surface of the horizontal block 4411 and extends downward into the first drive guide groove 431. To ensure that the clamping block 441 moves only radially under the drive of the rotating ring 43 to achieve the clamping action, this embodiment provides a second sliding groove 424 on the limiting seat 42 to restrict the clamping block 441 to radial movement only. The second sliding groove 424 is specifically formed on the second annular enclosure 422. The upper surface of the annular body of the rotating ring 43 provides bottom support for the radial movement of the clamping block 441, and the second sliding groove 424 provides path guidance for the radial movement of the clamping block 441. Driven by the rotating ring 43, the clamping block 441 (specifically the vertical block 4412) moves along the second slide groove 424 from the outside of the limiting storage groove 423 to the inside of the limiting storage groove 423 to center and clamp the end plate 300.

[0071] Since the disc 200 is made of several thin sheets of a specific material pressed together, and the dimensional accuracy of its outer perimeter is extremely high, clamping is strictly prohibited on the outer perimeter surface of the disc 200. To address this, this embodiment utilizes the slight dimensional difference between the disc 200 and the end plate 300 to design the clamping range of the clamping block 441 to only clamp the outer perimeter of the end plate 300 and not the outer perimeter of the disc 200. This prevents the clamping block 441 from clamping the disc 200 during the clamping process.

[0072] The disc clamping assembly 45 includes a slider 451 slidably disposed within a first groove 415, a centering clamping rod 452 disposed on the slider 451 and extending upward through a limiting seat 42, and a second drive roller 453 disposed on the slider 451 and engaging with a second drive guide groove 432 for transmission. One end of the slider 451 extends into the bottom of the rotating ring 43, and one end of the first groove 415 passes through an annular mounting groove 414 to allow one end of the slider 451 to extend into the bottom of the rotating ring 43. The second drive roller 453 is mounted on the upper surface of the section of the slider 451 that extends into the bottom of the rotating ring 43 and extends upward into the second drive guide groove 432. The centering clamping rod 452 is disposed in the section of the slider 451 that extends into the space where the limiting seat 42 is located and extends upward into a limiting receiving groove 423, engaging with a waist-shaped hole feature on the disc 200.

[0073] Because the disc 200 has a vertically penetrating oblong hole 201, while the end plate 300 does not have a corresponding slot structure, the centering clamping rod 452 can extend into the oblong hole 201 of the disc 200 when the clamping and positioning module 4 presses the disc 200. However, when pressing the end plate 300, the end plate 300 body will interfere with the centering clamping rod 452. To solve this problem, this embodiment has optimized the structure of the disc clamping assembly 45. Specifically, the centering clamping rod 452 is movably mounted on the slider 451, and after penetrating the slider 451 downwards, it sits on a reset support block 454. A first elastic member 455 is provided below the reset support block 454 to push the reset support block 454 upwards. Under the action of the first elastic element 455, the drive reset support block 454 is kept in a high position, thereby keeping the centering clamping rod 452 in an extended state and retained in the limiting storage groove 423; when the end plate 300 is placed into the limiting storage groove 423, due to the interference of its own body, the centering clamping rod 452 will be pressed downward, causing the centering clamping rod 452 to retract downward into the slider 451, and then withdraw from the limiting storage groove 423, effectively solving the problem of interference between the centering clamping rod 452 and the end plate 300.

[0074] When the centering clamping rod 452 is extended, it has the function of positioning the disc 200 for insertion and the function of centering and clamping the disc 200; when the centering clamping rod 452 is retracted, it avoids the insertion of the end plate 300.

[0075] The lower surface of the mounting base 41 is provided with a third slide groove 417 below the first slide groove 415. The reset support block 454 is slidably disposed in the third slide groove 417. A first limiting plate 456 is provided at the bottom of the third slide groove 417. A first elastic element 455 is located in the third slide groove 417, with one end fixed to the first limiting plate 456 and the other end fixed to the reset support block 454. The centering clamping rod 452 extends downward into the third slide groove 417 and sits on the reset support block 454. The bottom of the first slide groove 415 is also provided with a first clearance slot 418 to avoid the movement of the centering clamping rod 452. The first clearance slot 418 connects the first slide groove 415 and the third slide groove 417. Through the above structural design, the centering clamping rod 452 can move horizontally and radially with the slider 451 and can also perform vertical extension and retraction movements, which satisfies both the centering and positioning requirements of the disc 200 and the position clearance requirements of the end plate 300. The disc base 421 of the limiting seat 42 is provided with a second clearance slot 4211 for the radial movement of the centering clamping rod 452.

[0076] Because the end plate 300 has angular requirements during assembly, a vertical angle recognition groove 301 is provided on the outer peripheral surface of the end plate 300 to effectively identify the angle of the end plate 300. To accurately position the angle of the end plate 300 during the press-fitting process and prevent incorrect angle press-fitting, this embodiment includes an end plate angle positioning component 410. The end plate angle positioning component 410 includes an end plate angle positioning rod 4101 that extends into the angle recognition groove 301 of the end plate 300 during positioning. In addition, since there is no vertical groove structure on the circumferential surface of the disc 200 corresponding to the position of the angle recognition groove 301 of the end plate 300, the end plate angle positioning rod 4101 will interfere with the placement of the disc 200 when it is placed into the limiting storage groove 423. In order to solve this problem, this embodiment sets the end plate angle positioning rod 4101 as a vertically telescopic structure. Specifically, the end plate angle positioning rod 4101 is vertically telescopically set in the mounting base 41. The end plate angle positioning assembly 410 also includes a third elastic member 4102 located at the bottom of the end plate angle positioning rod 4101 and pushing the end plate angle positioning rod 4101 upward to keep it in the extended state. The mounting base 41 is provided with a fourth slide groove 420. The end plate angle positioning rod 4101 is movably disposed in the fourth slide groove 420. The bottom of the fourth slide groove 420 is provided with a second limiting sealing plate 4103. The third elastic member 4102 is disposed in the fourth slide groove 420, with one end fixed to the end plate angle positioning rod 4101 and the other end fixed to the second limiting sealing plate 4103, thereby pushing the end plate angle positioning rod 4101 upward and keeping it in an extended state. When the disc 200 is placed into the limiting storage groove 423, the end plate angle positioning rod 4101 can retract into the mounting base 41 to avoid the position of the disc 200.

[0077] When the end plate angle positioning rod 4101 is extended, it has the function of angular positioning of the end plate 300; when it is retracted, it has the function of avoiding the disc 200 body.

[0078] Since the end plate angle positioning rod 4101 and the centering clamping rod 452 can only have corresponding positioning functions when they are extended, if the operator inserts the end plate 300 or the disc 200 at an incorrect angle, the corresponding end plate angle positioning rod 4101 or centering clamping rod 452 will be squeezed into a retracted state, resulting in the loss of positioning function. In order to prevent the end plate angle positioning rod 4101 and the centering clamping rod 452 from being squeezed back and causing the positioning function to fail when the end plate angle positioning rod 4101 and the centering clamping rod 452 need to have corresponding positioning functions, this embodiment provides a locking component 47.

[0079] The locking assembly 47 includes a first limiting locking rod 471 and a second limiting locking rod 472, which are horizontally slidably disposed within the mounting base 41 and move synchronously together. The first limiting locking rod 471 locks and unlocks the extension and retraction of the centering clamping rod 452 through horizontal movement; the second limiting locking rod 472 locks and unlocks the extension and retraction of the end plate angle positioning rod 4101 through horizontal movement; when the first limiting locking rod 471 and the second limiting locking rod 472 extend synchronously, the centering clamping rod 452 is locked and remains extended, while the end plate angle positioning rod 4101 is unlocked and can extend and retract freely up and down; when the first limiting locking rod 471 and the second limiting locking rod 472 retract synchronously, the end plate angle positioning rod 4101 is locked and remains extended, while the centering clamping rod 452 is unlocked and can extend and retract freely up and down.

[0080] The mounting base 41 has several horizontally extending mounting grooves 419. The first limiting locking rod 471 and the second limiting locking rod 472 are horizontally slidably mounted in the mounting grooves 419 and held in place by a set screw 475. The set screw 475 holds a ball bearing on one side of the surface of the first limiting locking rod 471 and the second limiting locking rod 472, so that the first limiting locking rod 471 and the second limiting locking rod 472 only have horizontal freedom within the mounting grooves 419. In order to limit the horizontal movement range of the first limiting locking rod 471 and the second limiting locking rod 472, a limiting groove 473 is provided on the first limiting locking rod 471 or the second limiting locking rod 472. A limiting pin 474 is fixedly installed in the mounting groove 419, which penetrates the limiting groove 473 vertically. The length of the limiting groove 473 limits the horizontal movement range of the first limiting locking rod 471 and the second limiting locking rod 472.

[0081] When the first limiting locking rod 471 is extended, one end of it extends horizontally to below the reset support block 454, thereby preventing the centering clamping plate 452 from retracting and locking the centering clamping plate 452 in the extended state.

[0082] When the second limiting locking rod 472 retracts, its main body blocks the end plate angle positioning rod 4101 from retracting, thereby preventing the end plate angle positioning rod 4101 from extending and locking the end plate angle positioning rod 4101 in the extended state. In this embodiment, the second limiting locking rod 472 is provided with an unlocking slot 4721, through which the third elastic member 4102 passes.

[0083] In this embodiment, two first limiting locking rods 471 are provided, corresponding to the positions of the two centering clamping rods 452. One second limiting locking rod 472 is provided, located between the two first limiting locking rods 471.

[0084] The centering clamping rod 452 and the end plate angle positioning rod 4101 not only perform their respective positioning functions, but also serve as a foolproof function. When the centering clamping rod 452 is locked in the extended state, the end plate 300 cannot be inserted; when the end plate angle positioning rod 4101 is locked in the extended state, the disc 200 cannot be inserted.

[0085] Several first detection components 46 are arranged in a ring within the space of the limiting and receiving groove 423. In this embodiment, three first detection components 46 are provided, with the three points forming a surface to ensure that the disc or end plate placed in the limiting and receiving groove 423 is horizontal and vertical, with its axis in a vertical state and its end face in a horizontal state. In other embodiments, four or more components may be provided. The first detection component 46 includes a vertically arranged sensing probe 461 and a first sensor 462 for sensing the signal of the sensing probe 461. The first sensor 462 is disposed at the bottom of the mounting base 41, and the sensing probe 461 is embedded in the mounting base 41, with one end extending upward into the limiting and receiving groove 423 and the other end extending downward to the end of the first sensor 462. When the first detection component 46 is working, it determines that the disc 200 or end plate 300 is correctly placed into the limiting storage slot 423 only when all the first sensors 462 have sensed that the sensing probe 461 has moved into place. And the first drive component 2 only starts to perform press-fit drive after the disc 200 or end plate 300 is accurately placed into the limiting storage slot 423.

[0086] In this embodiment, the horizontal movement of the first limiting locking rod 471 and the second limiting locking rod 472 is achieved by manual pushing. The first limiting locking rod 471 must extend to the position below the centering clamping rod 452 to perform the locking function. Similarly, the second limiting locking rod 472 can only perform the locking function after it moves to the position below the end plate angle positioning rod 4101. Therefore, the first limiting locking rod 471 and the second limiting locking rod 472 must be moved to their correct positions during horizontal movement. However, during manual operation, there is an inevitable risk of not pushing them to the correct positions. To solve this problem, this embodiment provides a second detection component 420 to detect whether the first limiting locking rod 471 and the second limiting locking rod 472 have been pushed to the correct positions. Specifically, the second detection component 420 includes a mounting plate 4201 fixedly connected to one end of the first limiting locking rod 471 and the second limiting locking rod 472, a sensing protrusion 4202 disposed on the mounting plate 4201, and a second sensor 4203 and a third sensor 4204 fixed on the first support plate 3 and sensing the position of the sensing protrusion 4202. In use, the operator pushes the mounting plate 4201 to move the first limit locking rod 471 and the second limit locking rod 472 horizontally. When the mounting plate 4201 is pushed towards the mounting base 41, the first limit locking rod 471 and the second limit locking rod 472 are extended. If the second sensor 4203 detects the sensing protrusion 4202, it is determined that the first limit locking rod 471 and the second limit locking rod 472 have extended to the correct position. When the mounting plate 4201 is pulled away from the mounting base 41, the first limit locking rod 471 and the second limit locking rod 472 are retracted. If the third sensor 4204 detects the sensing protrusion 4202, it is determined that the first limit locking rod 471 and the second limit locking rod 472 have retracted to the correct position. If neither the second sensor 4203 nor the third sensor 4204 detects a signal, it is determined that the first limit locking rod 471 and the second limit locking rod 472 have not moved to the correct position, and the system issues an alarm or prompt.

[0087] The rotary drive assembly 48 includes a mounting block 481 fixedly mounted on the outer peripheral surface of the rotating ring 43, a handle 482 fixed on the mounting block 481, and a second elastic member 483 that pulls the rotating ring 43 to keep the end plate clamping assembly 44 in a clamped state. The second elastic member 483 is arc-shaped and disposed on the outside of the first annular barrier 413, with one end fixed to the mounting block 481 and the other end fixed to a fixing pin 484. The fixing pin 484 is fixed to the disc body portion 411 of the mounting base 41, pulling the rotating ring 43 to a set angle state, thereby keeping the end plate clamping assembly 44 in a clamped state. When it is necessary to switch the end plate clamping assembly 44 to the loosened state, the operator moves the handle 482 to drive the rotating ring 43 to rotate to another set angle state, switching the end plate clamping assembly 44 to the loosened state.

[0088] After the clamping and positioning module 4 clamps the end plate 300 or the disc 200 onto the rotor shaft 400, the clamping and positioning module 4 needs to be reset upwards. Then, the end plate clamping assembly 44 and the disc clamping assembly 45 in the clamping and positioning module 4 remain in the clamping state. If the clamping and positioning module 4 is forcibly moved upwards, the parts are easily damaged. To solve this problem, this embodiment provides a locking rod 485 on the mounting block 481 to lock the rotating ring 43 in the loose state. The first annular enclosure 413 is correspondingly provided with a locking hole 4132 that cooperates with the locking rod 485. The locking rod 485 can move horizontally. When the mounting block 481 is moved to an angle position that keeps the end plate clamping assembly 44 and the disc clamping assembly 45 in the loose state, the mounting block 481 can be locked and fixed on the first annular enclosure 413 by pushing the locking rod 485 into the locking hole 4132, thereby realizing the angle locking of the rotating ring 43.

[0089] The horizontal movement of the locking rod 485 can be achieved by using a support rod structure in conjunction with a spring. For example, the locking rod 485 can be slidably mounted on a fixed support rod, and the support rod is equipped with a spring that holds the locking rod 485 in the extension direction. The spring's thrust keeps the locking rod 485 in the extended state. When the locking rod 485 is aligned with the locking hole 4132, the locking rod 485 automatically extends into the locking hole 4132. When the locking rod 485 avoids the locking hole 4132, it is blocked by the first annular retaining wall 413 of the mounting base 41, causing the locking rod 485 to compress the spring and be in the retracted state.

[0090] When the end plate clamping assembly 44 and the disc clamping assembly 45 are switched to the open state, the clamping and positioning module 4 can move upward to press the next part.

[0091] The first annular enclosure 413 is also provided with an avoidance slot 4133. The connection between the mounting block 481 and the rotating ring 43 moves within the range of the avoidance slot 4133 during the rotation of the rotating ring 43.

[0092] The bracket 1 is provided with several guide rods 11, which extend vertically. The first support plate 3 and the second support plate 6 are both slidably mounted on the guide rods 11 via guide sleeves 12. The movable end of the first driving member 2 is fixedly connected to the first support plate 3 via several connecting rods 21. In this embodiment, two second driving members 5 are provided, fixed on the bracket 1 and located above the two sides of the second support plate 6 respectively. The rotating end of the second driving member 5 is provided with a lead screw 51, which is parallel to the guide rods 11. The second support plate 6 is provided with a nut sleeve that cooperates with the lead screw 51. The second driving member 5 realizes the up and down movement of the second support plate 6, thereby driving the centering assembly 7 to achieve precise up and down movement. By setting two second driving members 5 to drive the two sides of the second support plate 6 to rise and fall synchronously, the centering accuracy of the centering assembly 7 is ensured, providing an important prerequisite for the subsequent accurate and reliable pressing of the end plate 300 and the disc 200.

[0093] The first support plate 3 is provided with a clearance groove (not shown in the figure) through which the centering component 7 passes.

[0094] The centering assembly 7 includes a mounting sleeve 71 fixed to the second support plate 6, a centering push rod 72 movably disposed within the mounting sleeve 71, and a fourth elastic element 73 that holds the centering push rod 72 downward to maintain its downwardly extended state. The centering push rod 72 extends downward from the bottom end of the mounting sleeve 72 and forms a pointed structure at its end, pressing downward against the top of the rotor shaft 400. It cooperates with the lower positioning clamping assembly supporting the rotor shaft 400 to achieve precise centering and positioning of the rotor shaft 400's core, ensuring both the vertical orientation of the rotor shaft 400's core and maintaining accurate positional precision. In this embodiment, the centering push rod 72 only has vertical floating capability. In other embodiments, the centering push rod 72 can also be configured as a rotating structure, i.e., the mounting sleeve 71 is rotatably disposed on the positioning assembly 7, and the centering push rod 72 is elastically floating vertically within the mounting sleeve 71.

[0095] The pressing mechanism 100 for compatible motor rotor discs and end plates in this embodiment includes the following steps in use:

[0096] (1) End plate pressing: The operator turns the handle 482 to drive the rotating ring 43 to rotate, switches the end plate clamping assembly 44 to the open state, and pulls the locking assembly 47 to the retracted state. The third sensor 4204 detects the signal, the second limit locking rod 472 retracts to the position, and then the first end plate is placed in the limit storage groove 423; the end plate angle positioning rod 4101 extends into the angle recognition groove 301 on the outer peripheral surface of the end plate to perform angle positioning of the end plate 300; the angle lock on the rotating ring 43 is released, and the second elastic member 4 Under the action of 83, the rotating ring 43 is driven to rotate, and the end plate clamping assembly 44 is switched to the clamping state to clamp the first end plate; the centering clamping rod 452 in the disc clamping assembly 45 is squeezed to the retracted state by the end plate; all the first sensors 462 in the first detection assembly 46 detect the signal and determine that the end plate is placed in place; the second driving member 5 drives the centering assembly 7 to move downward to perform upper centering limit on the rotor shaft 400; the first driving member 2 drives the clamping positioning module 4 to move downward to press the first end plate onto the rotor shaft 400;

[0097] (2) Disc pressing: The operator turns the handle 482 to drive the rotating ring 43 to rotate, switching the disc clamping assembly 45 to the open state; the clamping positioning module 4 and the centering assembly 7 are reset upward; the locking assembly 47 is pushed to the extended state, the second sensor 4203 detects the signal, and the first limit locking rod 471 extends into place; the operator places the first disc into the limit storage slot 423, releases the angle lock on the rotating ring 43, and drives the rotating ring 43 to rotate under the action of the second elastic element 483, driving the disc clamping assembly 45 to switch to the clamping state, the centering clamping rod 452 clamps the disc 200, and the end plate angle positioning rod 4101 is squeezed to the retracted state; all the first sensors 462 in the first detection assembly 46 detect the signal, and it is determined that the disc is placed in place; the centering assembly 7 descends to center and position the rotor shaft 400, and the clamping positioning module 4 moves downward to press the first disc onto the rotor shaft 400;

[0098] (3) Repeat the disc pressing steps until all discs are pressed; repeat the end plate pressing steps to complete the pressing of the second end plate.

[0099] Example 2:

[0100] Please refer to Figures 14-15This embodiment is a pressing mechanism 100 compatible with motor rotor discs and end plates. Its structure is basically the same as that of Embodiment 1, except that the pressing mechanism 100 includes a bracket 1, a first driving member 2 fixed on the bracket 1, a first support plate 3 driven by the first driving member 2 to move up and down on a guide rod 11, a clamping and positioning module 4 disposed on the first support plate 3, a second support plate 6 movably disposed on the guide rod 11 and located above the first support plate 3, and a centering assembly 7 disposed on the second support plate 6 for positioning the rotor shaft 400. The second support plate 6 rests freely on the first support plate 3.

[0101] The centering component 7 and the second support plate 6 move downward together with the first support plate 3 under their own weight. During the descent, the top of the rotor shaft 400 first contacts the centering component 7. As the first support plate 3 continues to descend, the centering component 7 cooperates with the guide positioning hole at the top of the rotor shaft 400 and achieves the positioning of the rotor shaft 400 core under its own weight.

[0102] The centering assembly 7 includes a mounting sleeve 71 fixed to the second support plate 6, a guide sleeve 74 rotatably disposed within the mounting sleeve 71, a centering rod 72 whose upper part is movably disposed within the guide sleeve 74, and a fourth elastic member 73 that holds the centering rod 72 downward to keep it in a downwardly extended state. To prevent the centering rod 72 from slipping out of the guide sleeve 74, in one embodiment, the centering rod 72 can be hung in the guide sleeve 74 by the fourth elastic member 73; in another embodiment, a limiting protrusion (such as a transverse pin, a raised ring, or other structure) can be provided on the section of the centering rod 72 exposed in the guide sleeve 74, and the size of the perforation on the first support plate 3 can be used to prevent the centering rod 72 from sliding downward; in addition, the height gap between the first support plate 3 and the second support plate 6 limits the range of motion of the centering rod 72 relative to the guide sleeve 74.

[0103] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
