[0047] As a detailed explanation, the interior of the fitting frame 3 is rotatably provided with a bidirectional threaded rod 817, and the top and bottom of the surface of the bidirectional threaded rod 817 are threadedly connected with a threaded sleeve 818, and one side of the threaded sleeve 818 is fixedly connected to the surface of the retraction ring 819 through a bracket, and the interior of the fitting frame 3 is fixedly connected with a guide slide rod 820, and the top and bottom of the surface of the guide slide rod 820 are slidably provided with a guide sleeve 821, and one side of the guide sleeve 821 is fixedly connected to the surface of the retraction ring 819 through a bracket.

[0048] The present invention also discloses a motor stator processing and winding method, which specifically includes the following steps:

[0049] Step 1: Stator processing and positioning: according to Figure 1 and Figure 9As shown, first, the stator 4 is placed inside the fitting frame 3, and then the bidirectional threaded rod 817 is screwed, causing the threaded sleeve 818 to drive the retraction ring 819 to move toward the middle of the bidirectional threaded rod 817. The movement of the retraction ring 819 will press the inclined surface of the bending rod 816, causing the multiple bending rods 816 to be forced to drive the multiple receiving frames 804 to move toward the center of the fitting frame 3. When the receiving frames 804 move to the extreme position, the receiving frame 804 at the top will block the top of the stator 4.

[0050] Step 2, stator winding: Using an on-site winding device, a copper wire coil 703 is regularly wound on the surface of the winding mold frame 702 for a specified number of turns. Subsequently, the electric telescopic rod 704 in the automatic assembly mechanism 7 is activated, causing the extended end of the electric telescopic rod 704 to drive the winding mold frame 702 down to the coil assembly position. After the descent is completed, the copper wire coil 703 is clamped into the wiring slot of the stator 4 using the U-shaped assembly frame 715. Simultaneously, while the copper wire coil 703 is being assembled on the stator 4, the assembled copper wire coil 703 is simultaneously compacted at multiple stations.

[0051] The specific steps are: Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 13 、 Figure 14 and Figure 15 As shown, the electric telescopic rod 704 is started, and the extended end of the electric telescopic rod 704 drives the outer expansion ring 705 and the handle pressure plate 706 to descend. The bottom of the handle pressure plate 706 is blocked by the L-shaped movable frame 708, so the L-shaped movable frame 708, the inclined block 707 and the winding mold frame 702 are synchronously lowered until the winding mold frame 702 descends to the top of the U-shaped base 709. When the winding mold frame 702 descends to the top of the U-shaped base 709, the winding mold frame 702 is flush with the stator 4. When the winding mold frame 702 descends to the top of the U-shaped base 709, the inclined expansion plate 710 will be squeezed and contacted with the descending inclined block 707, causing the inclined block 707 to retract and cling to the side of the inclined expansion plate 710. Because the inclined block 707 is displaced by force, the inclined block 707 will carry the L-shaped movable frame 708 and stagger the bottom of the handle pressure plate 706.

[0052] When the handle pressing plate 706 descends and drives the inclined surface block 707 to squeeze and contact the side of the inclined surface expansion plate 710, the outer expansion ring 705 will descend along with the handle pressing plate 706, and will be located on the inclined surface of several inclined rods 716 and contact the inclined surface of the inclined rods 716. As the outer expansion ring 705 and the handle pressing plate 706 continue to descend, the outer expansion ring 705 will squeeze the inclined rods 716, prompting the inclined rods 716 to drive the U-shaped assembly frame 715 to move, and finally prompting the U-shaped assembly frame 715 in the limiting frame 701 to assemble the copper wire coil 703 in the wiring duct of the matching frame 3. The other U-shaped assembly frames 715 move synchronously, and the copper wire coil 703 in the assembled position is repeatedly compacted.

[0053] As the handle pressing plate 706 continues to descend along with the above-mentioned outward expansion ring 705, the handle pressing plate 706 will carry the flip plate 712 to contact the top of the L-shaped movable frame 708. The descending flip plate 712 is blocked by the L-shaped movable frame 708 and flips upward, and is misaligned with the L-shaped movable frame 708, and finally lies at the bottom of the horizontal bending part of the L-shaped movable frame 708, and is reset and unfolded synchronously. When the handle pressing plate 706 is reset subsequently, the handle pressing plate 706 will pre-expand and squeeze the L-shaped movable frame 708 through the upper inclined surface of the flip plate 712, so that the L-shaped movable frame 708 is pressed outward. The movable frame 708 drives the inclined block 707 and the inclined expansion plate 710 to break away from the extrusion and close fit, and the flip plate 712 synchronously expands and squeezes with the L-shaped movable frame 708 to accompany the rise and reset of the handle pressure plate 706 and drive the winding mold frame 702 to rise and reset. After the winding mold frame 702 is pulled to the top of the inner cavity of the limit frame 701, the handle pressure plate 706 will continue to rise, prompting the flip plate 712 to increase the force of squeezing and expanding the L-shaped movable frame 708, prompting the flip plate 712 to pass over the top of the L-shaped movable frame 708 and restore its original position.

[0054] Step 3: Temporary tightening of the winding: The U-shaped assembly frame 715 in the limiting frame 701 is driven by the electric telescopic rod 704. When the copper wire coil 703 is assembled, the U-shaped assembly frame 715 is synchronously linked with the anti-loosening tensioning mechanism 8, prompting the U-shaped tensioning frame 810 and the movable top plate 811 in the anti-loosening tensioning mechanism 8 to tighten the copper wire coil 703 into the wiring slot of the stator 4;

[0055] The specific steps are: Figure 3 、 Figure 4 、 Figure 5 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, the front U-shaped assembly frame 715 is squeezed and matched by the outer expansion ring 705 and the inclined rod 716, and the front U-shaped assembly frame 715 will move forward to assemble the copper wire coil 703, and the front U-shaped assembly frame 715 will synchronously drive the two connecting plates 822 to move. The movement of the two connecting plates 822 will squeeze and contact the tooth plate 815, prompting the tooth plate 815 to move. The tooth plate 815 is forced to move and mesh with the third gear 813. The third gear 813 is synchronously counter-engaged with the tooth limit block 814, prompting the telescopic plate 805 to extend from the storage frame 804, and the telescopic plate 805 synchronously drives the U-shaped tensioning frame 810 and The movable top plate 811 moves and approaches the copper wire coil 703. When the movable top plate 811 moves, it will gradually disengage from the roller 812, thereby prompting the U-shaped tensioning frame 810 and the movable top plate 811 to be pulled by the pull-back rod 808 and move vertically toward the sleeve 807. Finally, the U-shaped tensioning frame 810 will be at the rear side of the copper wire coil 703 that is moving forward on the front side. After the front U-shaped assembly frame 715 drives the connecting plate 822 to reset, the telescopic plate 805 will drive the U-shaped tensioning frame 810 to tighten the copper wire coil 703 assembled on the front side from back to front through the reset, and the surface of the movable top plate 811 is provided with a ball bearing.
