A Z-shaped positioning plate 84 is fixed on the top of the slide 83, and a fixing groove 841 for clamping the iron core is provided at the top of the Z-shaped positioning plate 84.

[0069] Working principle:

[0070] Step 1: The core loading assembly 3 is loaded.

[0071] First, the X-axis linear motor 331 and the Z-axis linear motor 332 move together to move the suction device 32 to the top of the material box 31, and the Z-axis linear motor 332 moves downward to enable the magnetic suction block 323 to absorb the iron core in the material box 31;

[0072] Subsequently, the X-axis linear motor 331 and the Z-axis linear motor 332 move in coordination to move the suction device 32 to the top of the belt conveyor 21, and the Z-axis linear motor 332 conveys the suction device 32 downward to make the bottom of the iron core contact with the belt of the belt conveyor 21;

[0073] Next, the stripping cylinder 3252 extends, causing the mounting plate 3253, the stripping rod 3254 and the stripping plate 3255 to move downward together. After the stripping plate 3255 contacts the top of the iron core, the Z-axis linear motor 332 drives the stripping plate 3255 to move upward, and the stripping cylinder 3252 continues to extend, separating the iron core from the magnetic suction block 323. At this time, the iron core is located on the belt of the belt conveyor 21.

[0074] Step 2: Conveying component 2 conveys the iron core.

[0075] First, the cylinder 23 is extended by limiting the X-axis so that the plurality of cores are located on the same straight line with the core baffle 22 and the movable plate 24;

[0076] Subsequently, the belt conveyor 21 drives the iron core forward, and the iron core moves to the bearing seat 252. The X-axis track-changing cylinder 251 drives the iron core and the bearing seat 252 to move together, and the bearing seat 252 moves to be in the same straight line as the iron core guide rail 26.

[0077] Next, the X-axis electric push rod 271 and the Y-axis inching cylinder 275 are used in conjunction with each other to position the iron core from the bearing seat 252 inside the U-shaped finger 274, and the Y-axis inching cylinder 275 drives the iron core to move forward one station along the iron core guide rail 26, just to the position facing the sleeve shaft preloading device 5;

[0078] Step 3: The sleeve shaft preloading device 5, the rotor shaft feeding assembly 4 and the fixing device 8 work.

[0079] First, the fixed finger cylinder 81 drives the two slides 83 and the Z-shaped positioning plate 84 to move, so that the iron core is fixed in the fixed groove 841;

[0080] Then, the manipulator 41 takes the rotor shaft out of the material tray and places it on the first pneumatic clamp 422. The first pneumatic clamp 422 clamps the rotor shaft, and the second pneumatic clamp 428 clamps the rotor shaft. The rack 424 is driven to move by the flip cylinder 423. The rack 424 moves to drive the first rotating shaft 425, the flip plate 427 and the second pneumatic clamp 428 to rotate together, so that the rotor shaft is aligned with the mounting hole of the iron core. The rotor shaft is clamped by the rotor shaft clamp 57, and the output end of the Z-axis alignment cylinder 53 is extended to insert the rotor shaft into the mounting hole of the iron core.

[0081] Finally, the rotor shaft clamp 57 is loosened a little, and the rotor shaft is preliminarily pressed into the installation hole of the iron core by the Z-axis pre-pressing cylinder 55 .

[0082] Step 3: The inching assembly 27, the shaft preloading device 6 and the fixing device 8 are started.

[0083] First, the inching assembly 27 transports the iron core and the rotor shaft that have been preliminarily pressed together by the sleeve shaft preloading device 5 to the shaft inlet preloading device 6, and drives the two slides 83 and the Z-shaped positioning plate 84 to move through the finger cylinder 81, so that the iron core is fixed in the fixing groove 841;

[0084] Subsequently, the precision pressing servo electric cylinder 61 drives the precision pressing head assembly 62 to press the rotor shaft tightly into the iron core.

[0085] Step 4: The inching assembly 27 and the core positioning assembly 7 are activated.

[0086] First, the inching assembly 27 transports the iron core and the rotor shaft, which have been precisely pressed together by the shaft preloading device 6, to the position facing the iron core positioning assembly 7;

[0087] Secondly, the X-axis telescopic cylinder 741 is started, so that the left clamping jaw 743 and the right clamping jaw 744 are located on the side of the iron core, and the left clamping jaw 743 and the right clamping jaw 744 are moved toward each other through the positioning finger cylinder 742. At the same time, the positioning cylinder 746 is extended, and the positioning cylinder 746 drives the slider 747 to slide along the right clamping jaw 744. Under the action of the torsion spring 749, the pusher claw 748 contacts the side of the iron core, and at the same time, the torsion spring 749 twists and accumulates force. During the extension process of the positioning cylinder 746, the pusher claw 748 moves close to the iron core. When the pusher claw 748 moves to the gap on the side of the iron core, the pusher claw 748 will be stuck in the gap on the side of the iron core under the action of the torsion spring, and the pusher claw 748 pushes the iron core to move together. When the positioning cylinder 746 is extended to the maximum position, the iron core completes axial positioning, and the positioning finger cylinder 742 clamps the iron core.
