A leaf spring 14 is arranged on the fixing frame 5 outside the two flaps 12, and the lower end of the leaf spring 14 is against the outer end of the flap 12, and the elastic force of the leaf spring 14 is used to press the bottom of the friction plate 13 at the lower end of the flap 12 against each other.

[0027] A guide plate 15 is disposed on the top of the fixing frame 5 in the reverse clamping plate assembly. A guide sinker tube 16 is disposed in the middle of the guide plate 15 . The guide sinker 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. A plurality of balls 21 are arranged in the hook-shaped sliding seats 20.

The sliding seat 17 is embedded in the slide groove 22 through the balls 21 in the two sets of hook-shaped sliding seats 20, thereby realizing sliding on the mounting tube 2.

[0029] The two groups of guide roller assemblies 18 are arranged 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 on the outer surface of the mounting tube 2, and the roller shaft 24 is rotatably connected to the two support plates 23.

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

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

[0033] The principle of the present invention is as follows: when in use, the wire pressing mechanism is first installed on the bed through the rotating shaft 28, and the rotation and up and down movement of the wire pressing mechanism are controlled by the bed. The enameled wire first passes between the two wire wheels 6 in the wire assembly. During the rotation of the wire pressing mechanism, the wire wheel 6 can ensure that the enameled wire is always in the installation tube 2 and will not fall out. After passing through the wire assembly, the enameled wire passes between the rubber wheel 10 and the transverse bevel gear 11. The two ends of the rubber wheel 10 and the transverse bevel gear 11 can be fixed to the fixing frame 5 by screws. When the diameter of the enameled wire is thicker, the screws can also be loosened to adjust the distance between the two, and the enameled wire is clamped. The rubber roller and the transverse bevel gear 11 are both non-metallic materials and will not cause damage to the surface of the enameled wire. After passing through the power assembly, it passes into the wire board of the reverse frame assembly, passes out from between the two flaps 12, and finally passes out after passing through the guide tube 30;

[0034] During the winding process, the enameled wire will be continuously led out by the overall movement of the wire pressing mechanism. After the winding is completed, the second servo micro motor 19 rotates to drive the sliding seat 17 to move downward, and the enameled wire is clamped and cut by the wire cutting cylinder 29. The wire cutting cylinder 29 has the functions of cutting and clamping the enameled wire. After cutting, the end of the enameled wire can be directly fixed on the mold for clamping the stator or rotor, and the sliding seat 17 can be controlled to move upward to continue winding. The wire cutting cylinder 29 includes a cylinder and a pair of scissors, which is a conventional technology in the existing field, so it is not described in detail;

[0035] When the wire is cut or wound, if the enameled wire breaks and retracts, the rotation of the first servo micro motor 7 is controlled, and the longitudinal bevel gear 8 drives the transverse bevel gear 11 to rotate, so as to drive the enameled wire to move and extend. The longitudinally arranged first servo micro motor 7 can reduce the size of the wire pressing mechanism, so that it is convenient to extend into the stator of the motor.

[0036] The flap 12 in the one-way frame assembly is supported by the elastic force of the leaf spring 14, and the friction plate 13 at the bottom always presses against the surface of the enameled wire, so that the enameled wire can slide smoothly when it moves downward. When retraction occurs, the friction plate 13 will hold the enameled wire and prevent retraction by friction. The friction plate 13 can be made of materials with greater friction such as rubber.

[0037] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
