Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically to a stator winding assembly device for motor assembly. Background Technology

[0002] Electric motor manufacturing is undoubtedly a crucial sector within the entire machinery manufacturing industry. Electric motors play an indispensable role in modern industrial systems and numerous aspects of daily life. Their core function is to generate driving torque; this powerful force acts like the "heart" of machinery, continuously supplying power to various electrical appliances and diverse mechanical devices, enabling them to operate smoothly.

[0003] Because the casing is too long, the effective stroke of the press is insufficient. In addition, because the casing is made of aluminum, it is easy to damage the stator winding. Therefore, a hot-fitting process is adopted to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a stator winding assembly device for motor assembly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stator winding assembly device for motor assembly, comprising a long cylindrical housing, a heating mechanism disposed inside the long cylindrical housing, and a fixing mechanism disposed on the top of the long cylindrical housing.

[0006] The heating mechanism includes a stator winding body, which is disposed inside a long cylindrical housing. A stator winding positioning fixture is fixedly connected to the bottom of the stator winding, and a stator winding base is fixedly connected to the bottom of the stator winding positioning fixture. Vertical plates are fixedly connected to both sides of the stator winding base, and horizontal plates are fixedly connected to the surface of the vertical plates. A limit rod is fixedly connected to the top of the horizontal plates. A connecting block is fixedly connected to the surface of the long cylindrical housing, and a limit groove is formed in the connecting block. The limit rod is inserted into the limit groove.

[0007] Preferably, the surface of the limiting rod is provided with threads, and a locking nut is threadedly connected to the surface of the limiting rod. The locking nut is located on the top of the connecting block. By threading the locking nut to the surface of the limiting rod, the purpose of installing the stator winding body inside the long cylindrical housing can be achieved.

[0008] Preferably, a connecting plate is fixedly connected to the side of the vertical plate away from the horizontal plate. The connecting plate has a placement groove, and a limiting plate is inserted into the placement groove. Both limiting plates are fixedly connected to both sides of the stator winding base. The stator winding can be positioned by the limiting plates.

[0009] Preferably, the stator winding base is circular, and the stator winding body is fitted to the inner wall of the long cylindrical housing.

[0010] Preferably, the surface of the stator winding base is provided with a slot, and the stator winding positioning fixture is engaged in the slot.

[0011] Preferably, the fixing mechanism includes a fixing member, which is fixedly connected to the top of the long cylindrical housing. A placement plate is fixedly connected to the surface of the fixing member, and mounting holes are provided on both sides of the placement plate. The mounting holes are designed with an arc shape.

[0012] Preferably, both sides of the fixing member are fixedly connected to fixing plates. The fixing plates are fixedly connected to the top of the long cylindrical housing by bolts. The placement plates are fixed through the mounting holes opened on both sides of the placement plates, thereby realizing the positioning of the long cylindrical housing and facilitating the subsequent assembly of the stator winding body.

[0013] Compared with the prior art, the present invention provides a stator winding assembly device for motor assembly, which has the following advantages:

[0014] 1. The stator winding assembly device for this motor assembly uses a heating mechanism to maintain the long cylindrical housing at a certain temperature and time in the heating equipment. After heating for a certain time, the housing expands due to heat, and the inner diameter of the housing increases. The stator winding is then lifted and placed into the housing. After the lower plane of the stator contacts the stator winding positioning jig, it does not move. After being placed at room temperature for a period of time, the housing size decreases due to the temperature drop (returning to the mating size), so that the inner diameter of the housing tightly hugs the outer circle of the stator winding and no longer moves, ensuring the housing size and reducing the assembly difficulty.

[0015] 2. The stator winding assembly device for this motor assembly uses a fixing mechanism to fix the placement plate through mounting holes on both sides of the placement plate, thereby achieving the positioning of the long cylindrical housing and facilitating the subsequent assembly of the stator winding body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] Example 1:

[0026] Combination Figures 1 to 2 -4, a stator winding assembly device for motor assembly, including a long cylindrical housing 1, a heating mechanism 2 disposed inside the long cylindrical housing 1, and a fixing mechanism 3 disposed on the top of the long cylindrical housing 1.

[0027] The heating mechanism 2 includes a stator winding body 29, which is disposed inside the long cylindrical housing 1. A stator winding positioning fixture 22 is fixedly connected to the bottom of the stator winding. A stator winding base 21 is fixedly connected to the bottom of the stator winding positioning fixture 22. Vertical plates 25 are fixedly connected to both sides of the stator winding base 21. A horizontal plate 26 is fixedly connected to the surface of the vertical plate 25. A limit rod 27 is fixedly connected to the top of the horizontal plate 26. A connecting block 28 is fixedly connected to the surface of the long cylindrical housing 1. A limit groove is opened in the connecting block 28, and the limit rod 27 is inserted into the limit groove.

[0028] Furthermore, the surface of the limiting rod 27 is provided with threads, and a locking nut is threadedly connected to the surface of the limiting rod 27. The locking nut is located on the top of the connecting block 28. By threading the locking nut to the surface of the limiting rod 27, the purpose of installing the stator winding body 29 inside the long cylindrical housing 1 can be achieved.

[0029] Furthermore, a connecting plate 24 is fixedly connected to the side of the vertical plate 25 away from the horizontal plate 26. A placement groove is provided in the connecting plate 24, and a limiting plate 23 is inserted into the placement groove. Both limiting plates 23 are fixedly connected to both sides of the stator winding base 21. The stator winding can be positioned by the limiting plates 23.

[0030] Furthermore, the stator winding base 21 is circular in design, the stator winding body 29 is fitted to the inner wall of the long cylindrical housing 1, and a slot is provided on the surface of the stator winding base 21, into which the stator winding positioning fixture 22 is engaged.

[0031] Example 2:

[0032] See Figure 5 Furthermore, based on Embodiment 1, the fixing mechanism includes a fixing member 33, which is fixedly connected to the top of the long cylindrical housing 1. A placement plate 34 is fixedly connected to the surface of the fixing member 33. Mounting holes 31 are provided on both sides of the placement plate 34, and the mounting holes 31 are designed in an arc shape.

[0033] Furthermore, fixing plates 32 are fixedly connected to both sides of the fixing member 33. The fixing plates 32 are fixedly connected to the top of the long cylindrical housing 1 by bolts. The placement plate 34 is fixed through the mounting holes 31 opened on both sides of the placement plate 34, thereby realizing the positioning of the long cylindrical housing 1 and facilitating the later assembly of the stator winding body 29.

[0034] In actual operation, when this device is used, the long cylindrical housing 1 can be placed in the corresponding position and the placement plate 34 can be fixed through the mounting holes 31 on both sides of the placement plate 34, thereby realizing the positioning of the long cylindrical housing 1, which facilitates the later assembly of the stator winding body 29.

[0035] Next, by placing the stator winding body 29 inside the long cylindrical housing 1, when the stator winding base 21 is tightly attached to the bottom of the long cylindrical housing 1, the limiting plate 23 is inserted into the placement groove opened inside the connecting plate 24, and the limiting rod 27 is inserted into the limiting groove opened inside the connecting block 28. Then, by connecting the locking nut threaded to the surface of the limiting rod 27, the purpose of installing the stator winding body 29 inside the long cylindrical housing 1 can be achieved. The long cylindrical housing 1 is kept at a certain temperature and time in the heating equipment. After heating for a certain time, the housing expands due to heat, and the inner diameter of the housing increases. The stator winding is lifted and placed into the housing. After the lower surface of the stator contacts the stator winding positioning jig 22, it does not move. After being placed at room temperature for a period of time, due to the decrease in temperature, the size of the housing decreases (returning to the mating size), so that the inner diameter of the housing hugs the outer circle of the stator winding and no longer moves, ensuring the housing size.
