DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] The traditional method of stator coil wire end correction mainly relies on manual operation. Manual correction is not only inefficient and difficult to meet the needs of large-scale production, but the correction effect is often not stable enough, and it is difficult to ensure that each coil wire end can meet the standard requirements. In addition, manual correction also has problems such as high labor intensity and cumbersome operation, which is not conducive to the automation and intelligent upgrading of the production line.

[0023] In view of the above problems, there is an urgent need for an efficient, stable and easy-to-operate stator coil wire end correction device to improve production efficiency, ensure product quality, and promote the automation and intelligent development of the production process. As a device specially used for stator coil wire end correction, the correction machine can effectively solve the shortcomings of manual correction. Through mechanical structure and automatic control technology, it can achieve accurate correction of stator coil wire ends, greatly improving production efficiency and product quality.

[0024] Therefore, the development of a wire end correction machine for small motor stator coils can not only meet the current market demand for high-quality motors, but also promote technological progress and process innovation in the motor manufacturing industry, bringing significant economic and social benefits to enterprises.

[0025] Example:

[0026] Reference Figure 1-Figure 5 , a small motor stator coil wire end correction machine, including a workbench 1, which is the basis of the whole machine, all components are installed on the workbench 1, to ensure the stability and accuracy of the equipment, refer to Figure 2 An opening 101 and a base 102 matching the opening 101 are provided at the axis of the workbench 1. The stator is installed in the base 102. The base 102 is designed to be detachable and adjustable so as to adapt to stators of different specifications. It is used to clamp the stator so that the stator is in a predetermined position to ensure the correct position and direction of the thread end.

[0027] The straightening machine also includes: a shaping mechanism, which is arranged on the workbench 1 and is used to flatten and shape the thread ends through mechanical pressure. Figure 1 and Figure 2 and Figure 3 , including: a slide 2, a correction module 3 and a driving module 4.

[0028] Specifically, the driving module 4 includes a ring 401 and a motor 402. The ring 401 is rotatably mounted on the slide 2. The outer edge surface of the ring 401 is provided with a tooth groove 403 along the circumferential direction. The surface of the ring 401 is provided with a through groove 404 along the circumferential direction. The motor 402 is fixedly mounted on the workbench 1. The output end of the motor 402 is fixedly mounted with a first gear 405 that can mesh with the ring 401.

[0029] The slide table 2 is fixed on the workbench 1, and is provided with slide grooves 201 equidistantly along the circumferential direction. The number of the slide grooves 201 is consistent with the number of stator wire ends.

[0030] The deviation correction module 3 is slidably installed in the slide groove 201 and has a vertical pin 301. The vertical pin 301 is used to slide in the through groove 404 to achieve the shaping action of the thread end.

[0031] The straightening machine is started through the control system, and the motor 402 starts to rotate. The first gear 405 at the output end of the motor 402 meshes with the tooth groove 403 on the outer edge of the ring 401, driving the ring 401 to rotate. As the ring 401 rotates, the vertical pin 301 in the groove 404 slides in the slide groove 201, and the correction module 3 moves accordingly, applying uniform pressure to the thread head for shaping and correction. Multiple adjustments can be made as needed to ensure the correction effect.

[0032] Reference Figure 1 and Figure 5 , a heating mechanism is coaxially arranged in the stator, the number of heating ends of the heating mechanism is consistent with the number of stator wire ends, and is used to heat the wire ends; it includes a threaded sleeve 5, a second gear 6 and a heating pipe 7.

[0033] Specifically, the threaded sleeve 5 is rotatably mounted on the workbench 1 to support and adjust the heating pipe 7 .

[0035] like Figure 5 The heating pipe fitting 7 includes a heating ring 701, a threaded pipe 702 and a nozzle 703. The nozzle 703 is equidistantly installed on the heating ring 701 along the circumferential direction and is connected to the heating ring 701. One end of the threaded pipe 702 is connected and fixed to the heating ring 701, and the other end is threadedly installed in the threaded sleeve 5. The threaded pipe 702 is used for an external heat source.

[0036] When the ring 401 rotates, the vertical pin 301 in the groove 404 slides in the slide groove 201, and the deviation correction module 3 moves accordingly, exerting uniform pressure on the thread end to shape it. At the same time, the second gear 6 engages with the tooth groove 403 of the ring 401 to drive the thread sleeve 5 to rotate, and the heating pipe 7 heats the thread end synchronously, so that the thread end is fixed in a new shape.

[0037] As an alternative, refer to Figure 3 and Figure 4 The correction module 3 includes a hollow block 304, a horizontal rod 302 and a correction plate 303. One end of the horizontal rod 302 is movably installed in the hollow block 304 through an elastic member. The elastic member is preferably a spring 307. The correction plate 303 is installed at one end of the horizontal rod 302 away from the hollow block 304. The first shaping tooth 305 is fixedly installed on the side of the correction plate 303 facing the thread end.

[0038] Reference Figure 5The nozzle 703 slides on the base 102 , and a second shaping tooth 704 is fixed to one end of the nozzle 703 away from the heating ring 701 . Track grooves 705 are provided on the nozzle 703 on both sides of the second shaping tooth 704 , and an extension end 306 adapted to the track groove 705 is provided on the correction plate 303 .

[0039] Through the arrangement of the above structure, when the circular ring 401 rotates, the vertical pin 301 in the through groove 404 slides in the slide groove 201, and the correction module 3 moves accordingly. The first shaping tooth 305 on the correction plate 303 applies uniform pressure to the thread head for shaping. At the same time, the extension end 306 on the correction plate 303 is gradually inserted into the track groove 705, the position of the thread head is corrected and it is stuck in the second shaping tooth 704 to complete the correction operation.
