Technical Field

[0001] This utility model relates to the field of stator coil technology, specifically a stator coil tensioning device. Background Technology

[0002] When making the stator coil of an electric motor, a winding machine is first used to make the electromagnetic wire on the spool into a single disc-shaped electromagnetic coil. Then, a forming machine is used to shape the electromagnetic coil, and finally, it is installed into the stator core. The electromagnetic wire on the spool usually has uneven surface and left and right bends, which affects the winding quality and efficiency of the winding machine during the process of making the electromagnetic wire into an electromagnetic coil. In addition, the existing device still has some defects, such as...

[0003] For example, in the case of the motor stator coil tensioning corrector with the publication number CN219018646U, one end of the connecting arm is oscillatingly connected to the mounting plate, and the other end of the connecting arm is rotatably connected to a correction wheel; a lead screw is inserted through one end of each connecting arm adjacent to the corresponding correction wheel, and a spring is fixedly connected between the ends of the two lead screws; a horizontally set connecting plate is vertically fixed on the surface of the mounting plate, and a straightening component is fixed on the upper surface of the connecting plate. During the process of the electromagnetic wire passing through the two correction wheels of the flattening component, the uneven parts of the electromagnetic wire surface are flattened by the clamping force of the two correction wheels, and the electromagnetic wire can be straightened by the two correction wheels of the straightening component.

[0004] The above-mentioned device has some problems. It is cumbersome to use, the correction wheel has a poor correction effect, the clamping force has a low efficiency in flattening the electromagnetic wire, and the wire tightening device is not effective in tightening the wire.

[0005] Therefore, we propose a stator coil tensioning device to solve the problems mentioned above. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The device is equipped with a tensioning structure. The internal gears rotate, and due to the meshing of the gears and racks, the racks move on the slide bar and simultaneously drive the moving block below to move synchronously.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a stator coil tensioning device, including a body 1 and a switch 2. A door is provided on the right side of the body 1, and the door is connected to the body 1 via a hinge shaft. A handle is provided on the surface of the door. A first push rod 3 is provided inside the body 1, and the upper part of the first push rod 3 is connected to a pressure plate 4. A gear 5 is provided inside the body 1, and the gear 5 meshes with a rack 6. The rack 6 is mounted on a slide rod 7. A moving block 8 is provided at the front end of the rack 6, and a pressure shaft 9 is provided below the moving block 8. A blower 10 is provided above the moving block 8. A buffer mechanism is provided inside the body 1, and the buffer mechanism includes a slider 11. The slider 11 is located inside the body 1, and the front of the slider 11 is connected to a switch 2. The connecting plate 13 is connected, the surface of the slider 11 is provided with a first spring 12, and the front of the connecting plate 13 is connected to the roller shaft 14. A pad is provided on the slider 11, and the pad is symmetrical about the center of the slider 11. The pad is made of rubber. The buffer mechanism is symmetrical about the center of the machine body 1, and a roller shaft 14 is provided in front of each buffer mechanism. A rotating shaft 15 is provided inside the machine body 1. The rotating shaft 15 is symmetrical about the center of the machine body 1, and an outer clamping arm 16 is connected to each rotating shaft 15. An inner clamping arm 18 is provided inside each outer clamping arm 16. The rotating shaft 15 is connected to the outer clamping arm 16, and a second spring 17 is provided inside the outer clamping arm 16. The second spring 17 is connected to the inner clamping arm 18.

[0028] First, after moving the machine body 1 to the designated position, insert the wire into the machine body 1 through the wire inlet on the left side. Then, activate the first push rod 3 to raise and lower the pressure plate 4, adjusting its height so that the wire enters above the pressure plate 4. Activate switch 2 to rotate the gear 5 inside the machine body 1. Since gear 5 meshes with rack 6, rack 6 moves on slide rod 7, simultaneously moving the lower moving block 8. This causes the pressure shaft 9 below moving block 8 to squeeze the bent portion of the wire surface. During this squeezing, all dust on the wire surface is expelled. Finally, activate the blower 10 above moving block 8 to... Dust is blown off to prevent damage to the circuit surface during subsequent flattening. The flattened circuit passes through the middle of the rollers 14 on the upper and lower sides inside the machine body 1. At the same time, the first spring 12 drives the slider 11 to move in the slide groove inside the machine body 1. After the front roller 14 corrects the unevenness of the circuit, the outer clamping arms 16 on both sides inside the machine body 1 rotate simultaneously through the rotating shaft 15. This causes the inner clamping arms 18 inside the outer clamping arms 16 to clamp the circuit. During clamping, the second spring 17 inside contracts synchronously, causing the inner clamping arms 18 to correct the unevenness of the circuit on the left and right sides.

[0029] The body 1 has a take-up box 19 inside, and a motor 20 inside the take-up box 19. The motor 20 is connected to a first rotating block 21. The first rotating block 21 is connected to a take-up shaft 24 through a snap-fit ​​connection mechanism. The take-up shaft 24 is connected to the first rotating block 21 and a second rotating block 25 through a snap-fit ​​connection mechanism. A fourth spring 28 is provided on the surface of the second rotating block 25. The snap-fit ​​connection mechanism includes a second push rod 22 inside the first rotating block 21, and a first locking block 23 at the front end of the second push rod 22. The first locking block 23 engages with a slot on one side of the take-up shaft 24. A third spring 26 is provided inside the second rotating block 25, and the front of the third spring 26 is connected to a second locking block 27. The second locking block 27 engages with a slot inside the take-up shaft 24. The first locking block 23 is square, and the front of the second locking block 27 is semi-circular. The fourth spring 28 is provided on the surface of the second rotating block 25, and the second rotating block 25 passes through one side of the take-up box 19.

[0030] The corrected cable enters the take-up box 19. Simultaneously, the motor 20 inside the take-up box 19 is activated, driving the first rotating block 21 to rotate. This causes the take-up shaft 24 and the second rotating block 25 inside the first rotating block 21 to rotate synchronously, collecting the cable. During the collection process, the take-up shaft may sway from side to side. At this time, the second rotating block 25 moves in the through hole on one side of the take-up box 19 through the fourth spring 28. After the take-up shaft 24 has collected the cable, the second push rod 22 inside the first rotating block 21 is activated, causing the first locking block 23 to retract. This causes the first locking block 23 to disengage from the locking groove inside the take-up shaft 24. At this time, the handle on the right side of the machine body 1 is held and the door on the right side of the machine body 1 is opened through the hinge shaft. The take-up shaft 24 is then pulled backward, causing the locking groove below the take-up shaft 24 and the second locking block 27 inside the second rotating block 25, connected by the third spring 26, to disengage. The take-up shaft 24 is then removed and stored.

[0031] Working principle: When using the stator coil tensioning device, first move the machine body 1 to the designated position, then place the wire into the machine body 1 through the wire inlet on the left side of the machine body 1. Then, activate the first push rod 3 to raise and lower the pressure plate 4, adjusting the height of the pressure plate 4 so that the wire enters above the pressure plate 4. Activate the switch 2 to rotate the gear 5 inside the machine body 1. Because the gear 5 meshes with the rack 6, the rack 6 moves on the slide rod 7, simultaneously driving the moving block 8 below to move synchronously. This causes the pressure shaft 9 below the moving block 8 to press the bent portion of the wire surface into the machine body. During the pressing process, all the dust on the surface of the circuit is pressed out. Then, the blower 10 above the moving block 8 is activated to blow the dust off to prevent damage to the circuit due to dust on the surface during subsequent pressing. The flattened circuit passes through the middle of the rollers 14 on the upper and lower sides inside the machine body 1. At the same time, the first spring 12 drives the slider 11 to move in the slide groove inside the machine body 1. This allows the front roller 14 to correct any unevenness in the circuit. Then, the rotating shaft 15 drives the outer clamping arms 16 on both sides inside the machine body 1 to rotate simultaneously, causing the outer clamping arms to move. The inner clamping arm 18 inside arm 16 clamps the cable. During clamping, the second spring 17 inside contracts synchronously, causing the inner clamping arm 18 to correct any unevenness on the left and right sides of the cable. The corrected cable enters the take-up box 19. Simultaneously, the motor 20 inside the take-up box 19 is activated, driving the first rotating block 21 to rotate. This causes the take-up shaft 24 and the second rotating block 25 inside the first rotating block 21 to rotate synchronously, collecting the cable. During the collection process, the take-up shaft may sway from side to side. At this time, the second rotating block 25 is controlled by the fourth spring 28. The cable reel moves through the through hole on one side of the cable box 19. After the cable reel 24 has finished collecting the cable, the second push rod 22 inside the first rotating block 21 is activated to drive the first locking block 23 to retract. This causes the first locking block 23 to disengage from the locking groove inside the cable reel 24. At this time, the handle on the right side of the machine body 1 is held and the door on the right side of the machine body 1 is opened through the hinge shaft. The cable reel 24 is then pulled backward, causing the locking groove below the cable reel 24 and the second locking block 27 inside the second rotating block 25, which is connected by the third spring 26, to disengage. The cable reel 24 is then removed and stored.
