[0057] A high-frequency heating mechanism 2 is disposed above the first slide rail 11, and includes a heating coil 21 for heating the wall of the central hole of the rotor core 9;
[0058] A shaft feeding mechanism 3, which is used to clamp and move the rotor shaft 91 to the shaft temporary storage seat 31;
[0059] The shaft grabbing and rotor handling mechanism 4 comprises a moving seat 41, a shaft grabbing assembly 42 and a rotor handling assembly 43, wherein the moving seat 41 is slidably connected to the second slide rail 411, the shaft grabbing assembly 42 is slidably connected to the moving seat 41, the rotor handling assembly 43 is arranged on one side of the shaft grabbing assembly 42, and the rotor handling assembly 43 is slidably connected to the moving seat 41;
[0060] A press mechanism 5, which is arranged at one end of the first slide rail 11;
[0061] The screw fastening mechanism 6 is used to tighten the round nut 92 sleeved on the rotor shaft 91 and the rotor core 9 .
[0062] By respectively setting up a code scanning system in the high-frequency heating mechanism 2 and the pressing mechanism 5, the two-dimensional code on the surface of the rotor core is scanned and identified before heating and pressing the shaft, thereby realizing error-proofing detection.
[0063] Symmetrically arranged first pressing blocks 121 are provided on both sides of the first core positioning seat 12. The first pressing blocks 121 are rotatably mounted on the first core positioning seat 12. One end of the first pressing block 121 is connected to the first driving cylinder 122. A position sensor 123 is also provided on one side of the first pressing block 121. After the pre-assembly of the rotor core 9 on the first core positioning seat 12 is completed, the first pressing block 121 rotates with the extension of the piston rod of the first driving cylinder 122, pressing the upper surface of the rotor core 9, cooperating with the first positioning rod 131 and the second positioning rod 141 to fully position the rotor core 9, prevent the rotor core 9 from being offset, and facilitate the installation of the rotor shaft 91. At the same time, the position sensor 123 is used to detect whether the height of the upper surface of the rotor core 9 meets the requirements to ensure that the pre-assembly of the rotor core 9 is completed.
[0064] The high-frequency heating mechanism 2 also includes a bidirectional moving component, which includes a first sliding seat 22, a first lifting connecting plate 23 and a first lifting driving cylinder 24. The first sliding seat 22 is slidably connected to the first bracket 221, the first lifting connecting plate 23 is slidably connected to the first sliding seat 22, the heating coil 21 is arranged on the first lifting connecting plate 23, and the first lifting driving cylinder 24 is used to drive the first lifting connecting plate 23 to slide. When the high-frequency heating mechanism 2 is working, the heating coil 21 moves horizontally through the first sliding seat 22, so that the heating coil 21 switches between the two feeding and conveying units, and then the first lifting driving cylinder 24 drives the first lifting connecting plate 23 to move in the vertical direction, and the heating coil 21 passes through the first bracket 221 and extends downward into the center hole in the center of the rotor core 9, so as to achieve heating of the rotor core 9, so that the diameter of the center hole is increased, which is convenient for pressing the rotor shaft 91.
[0065] The high-frequency heating mechanism 2 also includes a temperature sensor 25, which is arranged on the frame below the first core positioning seat 12, and the position of the temperature sensor 25 corresponds to the heating coil 21. Before the heating coil 21 extends downward into the center hole in the center of the rotor core 9, the temperature sensor 25 detects through the first avoidance hole and the center hole whether the temperature distribution of the temperature field of the heating coil 21 is affected by the core, that is, if the heating coil is offset from the central axial hole of the core, the core blocks the temperature sensor from detecting the heating coil, thereby detecting whether the hole position is aligned. In addition, during the heating process, the temperature sensor 25 detects the heating effect of the heating coil 21.
[0066] The shaft feeding mechanism 3 also includes a first clamp 32, a Z-axis mover 33, an X-axis mover 34 and a Y-axis mover 35. The Z-axis mover 33 is used to drive the first clamp 32 to move along the Z-axis direction, the X-axis mover 34 is used to drive the Z-axis mover 33 to move along the X-axis direction, and the Y-axis mover 35 is used to drive the X-axis mover 34 to move along the Y-axis direction. The shaft feeding mechanism 3 is a three-axis feeding device. After the first clamp 32 clamps the rotor shaft 91, it moves in the Z-axis direction and the Y-axis direction to place the rotor shaft 91 at the shaft temporary storage seat 31. The first clamp 32 realizes switching between the two shaft temporary storage seats 31 by moving in the X-axis direction. The rotor shaft 91 adopts a 9-seat type feeding.
[0067] The press mechanism 5 includes a third bracket 51, a press mounting seat 52, a pressing plate 53 and a latch positioning assembly. The third bracket 51 is provided with a guide column 511. The press mounting seat 52 is slidably connected to the third bracket 51. The latch positioning assembly includes locking cylinders 512 symmetrically arranged at both ends of the third bracket 51. The piston rod end of the locking cylinder 512 is connected to a locking pin 513. The press mounting seat 52 is provided with a slot corresponding to the position of the locking pin 513. The press is fixedly installed on the press mounting seat 52. The pressing shaft 521 of the press passes through the press mounting seat 52 and is connected to the sliding connection seat 522. The sliding connection seat 522 is slidably connected to the pressing plate 53. The guide column 511 is passed through the pressing plate 53. A pressing head 531 is provided below the pressing plate 53. The pressing head 531 is detachably installed on the pressing plate 53. The pressing head 531 can be quickly changed according to different products.
[0068] The third bracket 51 is provided with a cylinder for driving the press mounting seat 52 to slide horizontally. The press mounting seat 52 slides horizontally by controlling the extension and retraction of the cylinder piston rod, so that the pressing shaft 521 is aligned with different pressing heads 531. Before the press mounting seat 52 slides horizontally, it is necessary to control the piston rod of the locking cylinder 512 to retract upward and the locking pin 513 to disengage from the press mounting seat 52 to release the lock. The locking cylinder 512 cooperates with the slide rails on the upper and lower sides of the press mounting seat 52 to fully lock the horizontal position of the pressing shaft 521, and cooperates with the support seat at the bottom (the support seat is the sliding connection seat 522), so as to effectively ensure the stable transmission of pressure and ensure that the rotor shaft 91 is pressed in smoothly.
[0069] The screw fastening mechanism 6 includes a rotor support seat, a fourth slide rail 61, a second lifting cylinder 62, a servo motor 63 and a sleeve 64. The rotor support seat is slidably connected to the fourth slide rail 61, the second lifting cylinder 62 is arranged at one side of the fourth slide rail 61, the servo motor 63 is fixedly mounted on the fourth lifting seat, the piston rod of the second lifting cylinder 62 is fixedly mounted at one end of the fourth lifting seat, and the sleeve 64 is fixedly mounted at the output end of the servo motor 63. The servo motor 63 drives the sleeve 64 to rotate, and the shape of the sleeve 64 matches the round nut 92. When the rotor handling assembly 43 moves the preliminarily assembled rotor to one end of the fourth slide rail 61, the rotor support seat slides to the end of the fourth slide rail 61 and supports the rotor, and then the rotor support seat slides along the fourth slide rail 61 to the bottom of the sleeve 64, the second lifting cylinder 62 drives the fourth lift seat downward, and the sleeve 64 is sleeved on the round nut 92, and then the servo motor 63 drives the sleeve 64 to rotate and lock the round nut 92.
[0070] A material unloading conveyor line 7 is arranged on one side of the screw fastening mechanism 6, and a transplanting assembly is arranged on one side of the material unloading conveyor line 7, and the transplanting assembly includes a fifth clamping jaw 71. The fifth clamping jaw 71 in the transplanting assembly can move in the Z axis and the X axis. After the rotor support seat moves to one side of the material unloading conveyor line 7 along the fourth slide rail 61, the fifth clamping jaw 71 first moves to the top of the rotor support seat through the X axis, then moves in the Z axis, descends to clamp the rotor, and then returns to its position, and places the rotor on the material unloading conveyor line 7 to realize unloading.
[0071] Working principle: When loading the rotor core 9, a number of silicon steel sheets are pre-stacked and assembled together on the first core positioning seat 12. When placing the silicon steel sheets, in order to ensure that multiple silicon steel sheets are coaxially arranged, the first positioning rod 131 on the first connecting seat 13 slides upward in the vertical direction and passes through the first avoidance hole on the first core positioning seat 12, and the silicon steel sheet is sleeved on the first positioning rod 131 to form a positioning. When the rotor core 9 is pre-assembled, the first positioning rod 131 moves downward and detaches from the first core positioning seat 12, and then the first core positioning seat 12 moves along the first slide rail 11 toward the high-frequency heating mechanism 2, and the central hole in the center of the rotor core 9 is heated by the heating coil 21 of the high-frequency heating mechanism 2. Afterwards, the first core positioning seat 12 moves along the first slide rail 11 to the second connecting seat 14, and the second positioning rod 141 of the second connecting seat 14 slides upward in the vertical direction, passes through the first avoidance hole on the first core positioning seat 12, and extends into the center hole of the rotor core 9. Then, when the pressing mechanism 5 presses the rotor shaft 91 into the center hole, it moves downward synchronously with the rotor shaft 91 to realize the positioning of the rotor core 9.
[0072] In the shaft grabbing and rotor handling mechanism 4, the moving seat 41 moves horizontally along the second slide rail 411. When the moving seat 41 moves to one side of the shaft temporary storage seat 31, the shaft grabbing assembly 42 clamps and lifts the rotor shaft 91 on the shaft temporary storage seat 31, and then the moving seat 41 moves to the core feeding mechanism 1, and the shaft grabbing assembly 42 moves the rotor shaft 91 to just above the rotor core 9 on the first core positioning seat 12, and the shaft grabbing assembly 42 is located just below the press mechanism 5. Since the shaft grabbing assembly 42 clamps the side wall of the rotor shaft 91, the pressure head of the press mechanism 5 then moves downward and plugs into place with the top of the rotor shaft 91, the shaft grabbing assembly 42 releases the rotor shaft 91 and retreats, and the rotor shaft 91 is pressed into the rotor core 9 by the pressure head that continues to move downward. During the pressing process of the rotor shaft 91, the rotor handling assembly 43 moves to align with the rotor core 9 being assembled through the moving seat 41, waiting for the rotor core 9 to be unloaded after assembly is completed. The rotor handling assembly 43 can clamp the assembled rotor and perform rotation and height lifting.
[0073] The rotor core in the equipment adopts double-station loading, and the rotor shaft adopts 9-seat loading. In conjunction with the code scanning system, the high-frequency heating mechanism 2 and the press mechanism 5 can switch back and forth between the left and right tracks and work continuously, avoiding the long waiting time of the press mechanism 5 and the loader caused by the long heating time of the rotor core in the single-track working mode. When one rotor core is heated, the other rotor core pressed into the rotor shaft is unloaded, and the operations are carried out in rotation, which improves the assembly efficiency of each link, while meeting the rapid switching of multiple models, and has a wider compatibility range and adaptability.
