Description

Technical Field

[0001] The utility model belongs to the technical field of enameled wire winding, and in particular relates to a wire nozzle positioning tool for a winding machine. Background Art

[0002] Enameled wire is a kind of electrical wire, which is often used to wind the coils of electrical equipment such as motors and transformers. In the automated production process of windings, the key step is to use a winding machine to wind the coils. During the winding process, attention should be paid to the coil density, winding uniformity, and coil compactness, etc. These factors will affect the electrical conductivity and mechanical strength of the coil.

[0003] In order to ensure that the arrangement of the enameled wire can be accurately controlled during the operation of the winding machine, the position of the wire nozzle in the winding machine needs to be pre-positioned in combination with the size of the core slot, that is, the distance between the wire nozzle needle tip and the wire nozzle fixing rod is pre-adjusted. The wire nozzle is generally set through the fixing rod, and the position of the wire nozzle in the fixing rod is moved to position it. The current tooling used for positioning the wire nozzle achieves the positioning purpose by contacting the wire nozzle fixing rod at one end and the wire nozzle needle tip at the other end. However, according to actual production needs, the distance between the wire nozzle needle tip and the wire nozzle fixing rod needs to be adjusted with the different sizes of the product core. At present, most companies produce tooling of different fixed lengths for actual selection. However, this practice not only increases costs, but also has poor flexibility and low versatility in the use of tooling.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0005] The utility model aims to provide a winding machine wire nozzle positioning tool, which can be reused and is used for positioning wire nozzles with different length requirements, and has high flexibility.

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] like Figure 1-Figure 2 As shown, a winding machine nozzle positioning tool in one embodiment of the utility model includes a positioning plate 1, a positioning block 2, an adjusting rod 3 and a locking piece. The positioning block 2 is used to contact with the nozzle fixing rod, and the positioning plate 1 is used to contact with the nozzle needle tip. The adjusting rod 3 and the locking piece cooperate to adjust the distance between the positioning block 2 and the positioning plate 1, so as to adapt to the distance between the nozzle needle tip and the nozzle fixing rod.

[0029] Specific reference Figure 1 The end face of the positioning block 2 is provided with a notch 23. According to the shape of the actual nozzle fixing rod, the notch 23 can be set to an arc or square shape. In this embodiment, the notch 23 is arc-shaped to adapt to the cylindrical nozzle fixing rod. The nozzle is generally set through the nozzle fixing rod. When in use, the positioning block 2 is abutted against the nozzle fixing rod so that the nozzle fixing rod is stuck in the notch 23. The arc-shaped notch 23 enables the positioning block 2 to accurately fit the nozzle fixing rod. During assembly, the notch 23 can face the positioning plate 1 or away from the positioning plate 1. When the notch 23 faces the positioning plate 1, the nozzle fixing rod needs to be inserted between the positioning plate 1 and the positioning block 2. When the notch 23 is away from the positioning plate 1, the positioning block 2 can be directly abutted against the nozzle fixing rod, which makes the operation simpler and faster.

[0030] In order to facilitate the movement of the positioning block 2, two adjusting rods 3 are provided and are parallel to each other. The two adjusting rods 3 are respectively connected to two opposite sides of the positioning plate 1. The positioning block 2 is located between the two adjusting rods 3. A slide groove 21 is provided on the side of the positioning block 2. The adjusting rod 3 is located in the slide groove 21. The cooperation between the adjusting rod 3 and the slide groove 21 guides the movement of the positioning block 2, so that the positioning block 2 can be directly slid.

[0031] Reference Figure 2 Furthermore, considering the friction between the positioning block 2 and the adjusting rod 3 when sliding, in order to reduce wear, the side of the adjusting rod 3 facing the positioning block 2 is chamfered to protect the positioning block 2 and the adjusting rod 3. On the other hand, when the positioning block 2 is assembled between the two adjusting rods 3, the chamfered setting is more conducive to assembly.

[0032] The locking member is a screw 4. A sliding hole 31 is formed on the adjusting rod 3 along the length direction. A positioning hole 22 is formed on the side of the positioning block 2. The positioning hole 22 is a threaded hole. The screw 4 passes through the sliding hole 31 and is inserted into the positioning hole 22. After the screw 4 is tightened, the nut of the screw 2 is pressed against the adjusting rod 3 to fix the positioning block 2. The sliding hole 31 is arranged along the length direction of the adjusting rod 3 to facilitate the movement of the screw 4 in the sliding hole 31, so that after the positioning block 2 moves, the screw 4 can be inserted into the positioning hole 22 of the positioning block 2.

[0033] It should be noted that the screw 4 is only a way to fix the positioning block 2 in this embodiment. In addition to the screw 4, the locking member can also be a locking pin. The locking pin includes a locking rod and a locking cap arranged at the end of the locking rod. The locking rod passes through the sliding hole 31 of the adjusting rod 3 and is inserted into the positioning hole 22 of the positioning block 2. The locking rod and the positioning hole 22 are interference fit, and the locking cap is used to press the adjusting rod 3 to achieve fixation.

[0034] When positioning the thread nozzle, slide the positioning block 2 according to the required length, adjust the distance between the side of the positioning plate 1 and the notch 23, and then insert the locking pin 4 into the positioning hole 22 of the positioning block 2 to fix the positioning block 2. Place the positioning block 2 against the thread nozzle fixing rod so that the thread nozzle fixing rod is inserted into the notch 23. At this time, you only need to adjust the position of the thread nozzle until the tip of the thread nozzle is in contact with the side of the positioning plate 1, and then fix the thread nozzle. If you need to adjust the position of the thread nozzle again, adjust the position of the positioning block 2 on the adjustment rod 3 accordingly. It is simple and convenient to use, highly flexible, and has a wide range of uses and high versatility.
