Description

Technical Field

[0001] The utility model belongs to the technical field related to coil winding in the electrical industry, in particular to a winding component with a winding nozzle outlet mechanism. Background Art

[0002] The motor is a common mechanical equipment. During processing, copper wire needs to be wound on the stator of the motor. This work is generally completed by a winding machine. The winding assembly in the winding machine is one of the important parts that transports the copper wire to the winding stator. The winding nozzle in the winding assembly is its core component. During the winding process, it is best to ensure that the copper wire after coming out of the winding nozzle bends downward, because when bending downward, it can avoid the problem of the wire end winding or being wrapped around the winding nozzle during the winding process.

[0003] The existing winding nozzle, such as the winding machine nozzle structure disclosed in patent publication number CN203434817U, includes a wire tube and a wire nozzle body, one end of the wire nozzle body is provided with a through hole, a bearing is provided in the through hole, one end of the wire tube is fixedly connected to the bearing, and the other end of the wire nozzle body is provided with a support block, the support block is provided with a recess opposite to the through hole, and a rotatable wire bridge located in the recess, and a wire outlet hole connected to the recess is provided on the side wall surface of the support block. When this structure guides the copper wire, after the copper wire passes through the wire tube, it passes through the bending and guiding effect of the annular groove 11a, and then passes through the ceramic conduit, thereby changing the copper wire's passing-out angle (that is, ensuring that the copper wire bends downward after passing through the ceramic conduit). However, this structural setting requires the addition of a cylinder, a support shaft supporting the cylinder, and a pair of bearings inside the nozzle body. The inner ring of the bearing is fixed on the support shaft, and the cylinder is sleeved on the outer ring of the bearing. Therefore, this structural setting has many components and a complex structure. In addition, the structure needs to be installed inside the nozzle body, which makes installation inconvenient and therefore needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] Example 1

[0029] See also Figure 1-9 As shown, the present embodiment discloses a winding assembly with a winding nozzle outlet mechanism, comprising a winding fork 1, one end of the winding fork 1 is connected with a wire tube 2 connected with the winding fork 1, and the other end of the wire tube 2 is provided with a wire outlet nozzle 3 connected with the wire tube 2 at the port (how the wire outlet nozzle 3 is installed in the wire tube 2 belongs to the conventional technology in this field, so it is not described in detail here), the other end of the wire tube 2 is externally connected with a wire nozzle sheath 4, the wire nozzle sheath 4 is close to the wire outlet nozzle 3, and a U-shaped wire threading channel 5 is provided on one side of the wire nozzle sheath 4.

[0030] Preferably, in order to limit the maximum movable trajectory on both sides of the copper wire, the U-shaped threading channel 5 includes a C-shaped front stop line 501 and a C-shaped rear stop line 502 that are symmetrical in front and back, and a C-shaped threading stop bar 503 distributed up and down is arranged between the C-shaped front stop line 501 and the C-shaped rear stop line 502. The two C-shaped threading stop bars 503 are mirror-set, and the two ends of the C-shaped threading stop bar 503 are respectively connected to the ends of the corresponding C-shaped front stop line 501 and the C-shaped rear stop line 502. A notch 401 is provided on the other side of the wire mouth sheath 4. The notch 401 is provided to facilitate the insertion of the wire cutting mouth and facilitate the later wire cutting. The above-mentioned structural arrangement can limit the maximum position of the copper wire moving left and right.

[0031] Preferably, in order to avoid damaging the copper wire, the outer side and the inner side of the C-shaped threading stop 503 are provided with arc-shaped wire hanging chamfers 504. By providing the arc-shaped wire hanging chamfers 504, damage to the copper wire is avoided.

[0032] Preferably, in order to facilitate the installation and disassembly of the wire nozzle sheath 4, an internal threaded hole 6 is symmetrically provided on both sides of the wire nozzle sheath 4, and a positioning through hole 7 is provided on both sides of the wire tube 2 relative to the end close to the wire outlet nozzle 3. The internal threaded hole 6 is aligned with a positioning through hole 7, and the internal threaded hole 6 is connected to the internal thread with a top screw 8 which can be inserted into the corresponding positioning through hole 7 after being locked. The above-mentioned structural arrangement can facilitate the quicker disassembly of the wire nozzle sheath 4 in the later stage, and the wire nozzle sheath 4 can be directly removed when it is not needed.

[0033] Preferably, in order to facilitate disassembly, the wire tube 2 is provided with a positioning through hole 29 on both sides of the end away from the wire outlet nozzle 3, and the winding flying fork 1 is provided with an internal threaded hole 2 10 aligned with the positioning through hole 2 9. Each internal threaded hole 2 10 is connected to the internal thread with a locking screw 11 which can be inserted into the corresponding positioning through hole 2 9 after being locked. The above structural arrangement can facilitate the faster disassembly of the wire tube 2 in the later stage.

[0034] This structure is achieved by arranging a wire mouth sheath 4 on the outer side of the lower end of the wire tube 2. The copper wire passes through the wire tube 2 from one end of the winding fork 1 and then passes through the wire outlet mouth 3. Then, it passes through the U-shaped wire threading channel 5 on the side and then uses the bottom of the U-shaped wire threading channel 5 to bend downward (that is, the C-shaped wire threading stop 503 below) to ensure that the copper wire first passes through the wire outlet mouth 3 and then passes through the U-shaped wire threading channel 5 to achieve the first 90-degree bend. Then, it is bent downward by the C-shaped wire threading stop 503 to achieve the second 90-degree bend, that is, the operation of bending the copper wire downward is realized. In addition, the wire outlet structure is simpler and has fewer components. In addition, the wire mouth sheath 4 is arranged on the outer side of the wire tube 2, which is also convenient for assembly and later disassembly.

[0035] Example 2

[0036] See also Figure 10 As shown, the general structure of a winding assembly with a winding nozzle outlet mechanism disclosed in this embodiment is the same as that of Example 1, except that, as a preference, in order to adjust the length of the winding assembly, three positioning through holes 29 are provided on both sides of the wire tube 2 and are spaced apart along the length direction of the wire tube 2. The positioning through holes 29 on both sides are symmetrically arranged. In this embodiment, by providing positioning through holes 29 of different heights on the wire tube 2, the depth of the wire tube 2 inserted into the winding fork 1 can be different, thereby adjusting the length of the entire winding assembly.

[0037] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
