A winding machine pressing mechanism

Abstract

A winding machine clamping mechanism belongs to the field of winding processing technology. By installing a one-way clamping plate assembly inside the mounting tube, the one-way clamping plate assembly prevents the enameled wire from retracting after being cut by the wire cutting clamping mechanism, reducing manual handling of the enameled wire and increasing winding efficiency. By installing a power component inside the mounting tube, the extension of the enameled wire can be controlled. When the enameled wire retracts, controlling the rotation of the first servo micro motor allows the enameled wire to be delivered, avoiding manual handling and reducing winding efficiency. By installing the wire cutting clamping assembly, the wire cutting cylinder can be directly integrated into the mounting tube, thus avoiding the need to guide the enameled wire to the frame assembly for clamping before cutting, effectively reducing waste of enameled wire and preventing increased costs.

Description

Technical Field

[0001] This invention belongs to the field of winding processing technology, specifically relating to a winding machine pressing mechanism. Background Technology

[0002] In existing technologies, winding operations during the production of motor rotors or stators are mostly performed using winding machines. However, after the winding is completed, the enameled wire usually needs to be guided to a clamping plate assembly on one side of the winding machine for clamping. During the process of cutting the enameled wire with a wire cutting device and guiding it to the clamping plate assembly, a significant amount of enameled wire is wasted, leading to increased costs. Furthermore, after the enameled wire is cut, it tends to retract, causing the end to retract into the guide tube. This requires manual tweezers to guide the wire end back out and re-clamp it onto the clamping plate assembly. While this is relatively easy with thicker enameled wires, it is cumbersome when clamping smaller diameter wires, resulting in a significant reduction in winding efficiency. Summary of the Invention

The transverse helical gear 11 is located on the rear side of the rubber wheel 10 and meshes with the longitudinal helical gear 8. The left and right sides of the rubber wheel 10 and the transverse helical gear 11 are rotatably connected to the fixing frame 5. The distance between the surface of the rubber wheel 10 and the transverse helical gear 11 can be adjusted according to the diameter of the enameled wire.

[0026] The fixed frame 5 in the one-way clamping plate assembly is provided with two flip plates 12. The top of the flip plates 12 is rotatably connected to the fixed frame 5, and the lower end of the flip plates 12 can be flipped around the top. The lower end of the two flip plates 12 is provided with friction plates 13. The friction plates 13 and the flip plates 12 are engaged by male and female sliding grooves 22 to facilitate the replacement of friction plates 13. A leaf spring 14 is provided on the fixed frame 5 on the outer side of the two flip plates 12. The lower end of the leaf spring 14 abuts against the outer end of the flip plate 12, and the elastic force of the leaf spring 14 abuts the bottom of the friction plates 13 at the lower end of the flip plates 12 against each other.

[0027] The top of the fixing frame 5 in the one-way clamping plate assembly is provided with a guide plate 15, and a guide tube 16 is provided in the middle of the guide plate 15. The guide tube 16 is coaxially arranged with the mounting tube 2.

[0028] The wire cutting clamping assembly includes a sliding seat 17, two sets of guide roller assemblies 18, and a second servo micro motor 19. The sliding seat 17 includes two sets of hook-shaped sliding seats 20. Each hook-shaped sliding seat 20 has multiple balls 21 inside.

The sliding seat 17 slides on the mounting tube 2 by having the balls 21 in the two sets of hook-shaped sliding seats 20 embedded in the grooves 22.

[0029] Two sets of guide roller assemblies 18 are located on the upper and lower sides of the slide groove 22, and each includes two support plates 23 and a roller shaft 24. The two support plates 23 are inserted into the outer surface of the mounting tube 2, and the roller shaft 24 is rotatably connected to the two support plates 23.

The synchronous belt 26 is wound around the synchronous pulley 25 and the two roller shafts 24 in sequence, and the synchronous belt 26 is connected to the sliding seat 17.

[0030] A longitudinal connecting rod 27 is connected to the connecting frame plate 1. A rotating shaft 28 is provided at the bottom of the longitudinal connecting rod 27. The axis of the rotating shaft 28 overlaps with the bending position of the guide tube 30.

[0031] The sliding seat 17 is equipped with a wire-cutting cylinder 29, which can cut the enameled wire of the motor. The position of the wire-cutting cylinder 29 is aligned with the position of the guide tube 30.

[0032] The wear-resistant sleeve 4 can be replaced according to the diameter of the motor enameled wire, and a suitable wear-resistant sleeve 4 can be selected according to the wire diameter of the motor enameled wire.

[0033] The principle of this invention: In use, the wire pressing mechanism is first installed on the bed via the rotating shaft 28. The bed controls the rotation and up-down movement of the wire pressing mechanism. The enameled wire first passes between the two guide wheels 6 in the guide assembly. During the rotation of the wire pressing mechanism, the guide wheels 6 ensure that the enameled wire remains inside the mounting tube 2 and will not come out. After passing through the guide assembly, the enameled wire passes between the rubber roller 10 and the transverse helical gear 11. The two ends of the rubber roller 10 and the transverse helical gear 11 can be fixed to the fixing frame 5 with screws. When the diameter of the enameled wire is thick, the screws can be loosened to adjust the distance between them and clamp the enameled wire. The rubber roller and the transverse helical gear 11 are both non-metallic materials and will not damage the surface of the enameled wire. After passing through the power assembly, the wire passes into the guide plate of the reverse frame assembly, passes out between the two flip plates 12, and finally passes through the guide tube 30 and then out.

[0034] During the winding process, the enameled wire is continuously drawn out by the overall movement of the wire pressing mechanism. After the winding is completed, the second servo micro motor 19 rotates, driving the sliding seat 17 to move down. The wire cutting cylinder 29 is used to clamp the enameled wire. The wire cutting cylinder 29 has the functions of cutting wire and clamping enameled wire. After cutting, the end of the enameled wire can be directly fixed to the mold that clamps the stator or rotor. By controlling the sliding seat 17 to move up, the winding can continue. The wire cutting cylinder 29 consists of a cylinder and scissors. It is a conventional technology in the existing field, so it will not be described in detail.

[0035] If the enameled wire breaks and retracts during the winding process, the rotation of the first servo micro motor 7 is controlled, and the longitudinal helical gear 8 drives the transverse helical gear 11 to rotate, thereby moving the enameled wire to extend. The longitudinally arranged first servo micro motor 7 can reduce the structural size of the wire pressing mechanism and make it easier to extend into the stator of the motor.

[0036] In the unidirectional frame assembly, the flap 12 is held in place by the spring force of the leaf spring 14, and the friction plate 13 at the bottom is always pressed against the surface of the enameled wire. It can slide smoothly as the enameled wire moves downward. When retraction occurs, the friction plate 13 will hold the enameled wire and prevent retraction through friction. The friction plate 13 can be made of a material with high friction, such as rubber.

[0037] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
