By adjusting the position of the winding mold on the fixed device and adjusting the distance between the two winding molds, it can be applied to winding of different lengths and improve the applicability.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to the following: Figs. 1-5 As shown, a motor winding mechanism is provided, including a winding mold and a fixing device 1. The fixing device 1 is provided with a mold positioning area and a drive shaft positioning area connected to the drive shaft. Multiple mold positioning areas are provided on both sides of the drive shaft positioning area, and winding molds are respectively provided on both sides of the drive shaft positioning area. The winding molds are detachably connected to the mold positioning areas. The specific working steps are as follows: two winding molds are respectively connected to the mold positioning areas on both sides of the drive shaft positioning area. The drive shaft drives the overall fixing device 1 to rotate, and the two winding molds rotate, thereby realizing the winding of the winding. When installing the winding mold, the winding mold can be selected to be installed in a certain mold positioning area as needed, and the distance between the winding molds on both sides of the drive shaft positioning area can be actively adjusted, that is, the length of the final formed winding can be adjusted. It can be applied to the winding of windings of different lengths, thus improving the applicability.

[0032] In this embodiment, the mold positioning area is the positioning hole 2, and the winding mold has a through hole 10 in the middle. The specific way in which the winding mold and the mold positioning area are detachably connected is as follows: one end of the threaded rod is connected to the first nut, and the other end passes through the positioning hole 2 and the through hole 10 in sequence and is connected to the second nut. The outer diameter of the first nut is larger than the diameter of the positioning hole 2, and the outer diameter of the second nut is larger than the diameter of the through hole 10. The first nut and the second nut on both sides are used to clamp and lock the fixing device 1 and the winding mold. Alternatively, a bolt is used to pass through the positioning hole 2 and the through hole 10 in sequence and is connected to the third nut. The outer diameter of the bolt head is larger than the diameter of the positioning hole 2, and the outer diameter of the third nut is larger than the diameter of the through hole 10. The bolt head and the third nut are used to clamp and lock the fixing device 1 and the winding mold. Alternatively, a bolt is used to pass through the through hole 10 and the positioning hole 2 in sequence and is connected to the third nut. The outer diameter of the bolt head is larger than the diameter of the through hole 10, and the outer diameter of the third nut is larger than the diameter of the positioning hole 2.

[0033] The diameter of the through hole 10 can be designed to match the diameter of the positioning hole 2, and the diameter of the through hole 10 can also match the outer diameter of the threaded rod or bolt, thus avoiding radial offset.

[0034] In other embodiments, the mold positioning area can also be a threaded hole. A through hole 10 is provided in the middle of the winding mold. The locking bolt passes through the through hole 10 and is threadedly connected to the threaded hole. The outer diameter of the locking bolt head is larger than the diameter of the through hole 10. The clamping, locking and positioning of the winding mold is achieved by using the fixing device 1 and the head of the locking bolt.

[0035] The diameter of the through hole 10 can be set to match the outer diameter of the locking bolt thread to avoid radial offset.

[0036] Multiple mold positioning areas on both sides of the drive shaft positioning area are arranged at equal intervals, so that the staff can easily calculate how to adjust the position of the winding mold according to the required mold spacing.

[0037] Alternatively, multiple mold positioning areas on both sides can be symmetrically set with the drive shaft positioning area as the center. This arrangement of multiple mold positioning areas at equal intervals makes it easier for staff to calculate how to adjust the position of the winding mold based on the required mold spacing.

[0038] The drive shaft positioning area includes a central hole 3 and an auxiliary hole 4. The central hole 3 is matched with the drive shaft and allows the drive shaft to pass through. The auxiliary hole 4 is connected to the flange bolts fixed on the drive shaft to realize the transmission between the drive shaft and the fixed device 1. At least two auxiliary holes 4 are provided to improve the connection strength with the flange.

[0039] In this embodiment, the fixing device 1 is a steel rectangular base plate, that is, a rectangular base plate made of steel. It has high structural strength and can improve service life. In other embodiments, the material and shape of the fixing device 1 can be selected according to actual needs. Other metals can be used as materials, and the shape can be circular or polygonal, etc.

[0040] The four corners of the steel rectangular base plate are rounded to prevent sharp corners from scratching workers.

[0041] In this embodiment, two types of winding molds are provided. One type of winding mold is a chain winding mold 5. The chain winding mold 5 has multiple annular grooves 6 along the direction away from the fixing device 1. The multiple annular grooves 6 have the same structure. The specific parameters of the annular grooves 6 are: groove opening width 10mm, groove bottom width 8mm, and groove depth 10mm.

[0042] Another type of winding mold is a cross-type winding mold 7. The cross-type winding mold 7 has multiple slot groups opened in the direction away from the fixing device 1. The slot group includes two first annular slots 8 and a second annular slot 9 opened sequentially in the direction away from the fixing device 1. The slot opening width of the first annular slot 8 is the same as the slot opening width of the second annular slot 9. The slot bottom width of the first annular slot 8 is greater than the slot bottom width of the second annular slot 9. The slot depth of the first annular slot 8 is less than the slot depth of the second annular slot 9. The specific parameters of the first annular slot 8 are: slot opening width 10mm, slot bottom width 8mm, and slot depth 10mm. The specific parameters of the second annular slot 9 are: slot opening width 10mm, slot bottom width 7mm, and slot depth 15mm.

[0043] The specific parameters of annular groove 6, first annular groove 8, and second annular groove 9 can also be designed as needed.

[0044] Annular groove 6, first annular groove 8, and second annular groove 9 are all circular annular grooves.

[0045] The grooves of both winding dies are formed by opening on a cylindrical structure, and the bottom of the winding die contacts the fixing device 1 with a flat surface to improve the structural strength.

[0046] You can choose to use either chain winding die 5 or cross winding die 7, depending on your actual needs.

[0047] Both types of winding dies have flared slots to gather the wound coils and improve the winding effect.
