[0044] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0045] like Figure 1-10 As shown, a horizontal wire embedding machine is used to embed copper wire into the wire slot of the stator core 100, including a frame 1, a support frame 2 arranged on the frame 1 for supporting the stator core 100 to be embedded with the wire, and a wire pushing mechanism 3 arranged on the frame 1 for pushing the wound copper wire into the stator core 100, wherein the support frame 2 can move along a first direction to approach or move away from the wire pushing mechanism 3, and the first direction is a horizontal direction.

[0046] The support frame 2 includes a first support plate 201 horizontally placed on the frame 1, and a plurality of second support plates 202 arranged along the first direction of the first support plate 201, wherein the plurality of second support plates 202 are aligned with each other in the first direction and the plane where each second support plate 202 is located is perpendicular to the first direction. Two parallel support rollers 203 are arranged on the plurality of second support plates 202, and the support rollers 203 are rotatable. The stator core 100 to be inserted with paper is placed on the two support rollers 203, and since the support rollers 203 are rotatable, the angle of the stator core 100 on the circumference can be conveniently adjusted.

[0047] A clamping piece 204 is provided on each second support plate 202, one end of the clamping piece 204 is hinged on the corresponding second support plate 202, the clamping piece 204 can be rotated to the top of the stator core 100, and the side of the clamping piece 204 in contact with the stator core 100 is in an arc shape, the diameter of the arc shape is the same as the diameter of the stator core 100, so that the stator core 100 can be clamped.

[0048] The wire pushing mechanism 3 includes a mounting plate 301 arranged on the frame 1, the plane where the mounting plate 301 is located is perpendicular to the first direction, and a mounting hole is arranged on the mounting plate 301, and the axis of the mounting hole is colinear with the axis of the stator core 100 located on the support roller 203. A fixed cylinder 302 is rotatably arranged in the mounting hole, and a plurality of guide grooves are arranged on the inner wall of the fixed cylinder 302 along its circumferential direction, and the guide grooves penetrate the fixed cylinder 302 in the first direction, and the number of the guide grooves is equal to the number of wire grooves of the stator core 100. A first guide rod 303 is arranged in each of the guide grooves, and the first guide rod 303 can move back and forth along the first direction. A second guide rod 304 is arranged on the inner side of the center of the circle surrounded by the first guide rods 303, and the second guide rod 304 corresponds to the first guide rod 303 one by one, and the second guide rod 304 can also move back and forth along the first direction.

[0049] Further, one end of the first guide rod 303 away from the support frame 2 is arranged on the first transmission block 309. One end of the second guide rod 304 away from the support frame 2 is arranged on the second transmission block 310, and the second transmission block 310 is closer to the support frame 2 than the first transmission block 309, and the first transmission block 309 and the second transmission block 310 can both move back and forth along the first direction.

[0050] Furthermore, the wire pushing mechanism 3 also includes a first driving rod 305, which extends along the first direction and is coaxially arranged with the fixed cylinder 302. One end of the first driving rod 305 is arranged on the first transmission block 309, and the other end is rotatably connected to the output shaft of the electric cylinder. The cylinder body of the electric cylinder is supported on the frame 1, and the output shaft of the electric cylinder moves back and forth along the first direction, thereby being able to drive the first driving rod 305 to move.

[0051] The first driving rod 305 is a cylindrical structure, and is provided with two notched grooves 308 extending along the first direction. When observed along the first direction, the two notched grooves 308 are arranged opposite to each other, and the notched grooves 308 are communicated with the interior of the first driving rod 305. The wire pushing mechanism 3 also includes a second driving rod 306, which is located in the first driving rod 305 and the two are coaxially arranged. One end of the second driving rod 306 passes through the first transmission block 309 and is connected to the second transmission block 310. The second driving rod 306 can move back and forth along the first direction relative to the first driving rod 305 and the first transmission block 309.

[0052] The wire pushing mechanism 3 also includes a moving block 307 disposed on the frame 1, and the moving block 307 can move back and forth along the first direction. The first driving rod 305 passes through the moving block 307, and the first driving rod 305 can move back and forth along the first direction and can rotate relative to the moving block 307. The moving block 307 is connected to the second driving rod 306 through a connecting rod 3071, and the connecting rod 3071 passes through the notch groove 308. The connecting rod 3071 cannot move along the first direction relative to the moving block 307, but the connecting rod 3071 can rotate relative to the moving block 307, thereby enabling the first driving rod 305 and the second driving rod 306 to rotate synchronously. The second driving rod 306 is driven by a screw rod and a motor.

[0053] A plurality of push blocks 3101 are arranged at equal angles on the outer edge of the second transmission block 10, and there is a push block 3101 between each of the adjacent second guide rods 304. The push blocks 3101 extend radially outwardly along the second transmission block 10 and extend out from the gaps between the adjacent second guide rods 304. The outer diameter of the circle formed by the second guide rods 304 is smaller than the inner diameter of the stator core 100, so that the second guide rods 304 can be inserted into the stator core. In practice, the outer diameter of the circle formed by the second guide rods 304 is slightly smaller than the inner diameter of the stator core 100. When embedding the wire, each push block 3101 corresponds to a wire slot of the stator core 100, and the wound coil is pre-hung on the corresponding second guide rod 304 manually, and the coil is located in the gap formed by the corresponding second guide rod 304, and then the support frame 2 moves toward the wire pushing mechanism 3 until a part of the second guide rod 304 is inserted into the stator core 100, at which time the first guide rod 303 extends from the fixed tube 302 and is inserted into the stator core 100 near one end of the stator core 100; then, the second transmission block 310 starts to move, moving the second guide rod 304 toward the other end of the stator core 100, and the push block 3101 pushes the coil toward the other end of the stator core 100. When the push block 3101 moves into place, the two ends of the coil are respectively located at the two ends of the stator core 100, and the middle part of the coil is located in the corresponding wire slot. Since multiple coils need to be embedded in the stator core 100, the embedding is generally performed in multiple times. After completing one embedding, the wound coil is first moved to the second guide rod 304. In the circumferential direction, the initial position of the coil relative to the second guide rod 304 is the same. When the coil is moved to the second guide rod 304, the second guide rod 304 and the first guide rod 303 are rotated by a predetermined angle to embed the corresponding wire groove.

[0054] Furthermore, a positioning ring 311 is sleeved on one end of the fixed cylinder 302 close to the mounting plate 301, and four positioning grooves 313 are arranged at equal angles on the outer edge of the positioning ring 311. A positioning block 311 is arranged on the mounting plate 301 and directly above the positioning ring 311. The positioning block 311 can be inserted into the positioning groove 313 to position the positioning ring 311, and then the fixed cylinder 302 can be positioned to prevent the fixed cylinder 302 from rotating on its own. The positioning block 311 can move up and down to be inserted into or pulled out of the positioning groove 313 as needed.
