Description

Technical Field

[0001] This utility model relates to the field of stator hoisting technology, specifically a novel stator assembly tooling structure. Background Technology

[0002] The stator is the stationary part of an electric motor or generator, mainly composed of three parts: the stator core, the stator windings, and the frame. The frame is used to fix the core, and for suspended generators, the frame bears the entire weight of the rotating parts. The core is part of the generator's magnetic circuit, and the coils form the generator's electrical circuit. The main function of the stator is to generate a rotating magnetic field. During the manufacturing or repair of electric motors or generators, the stator needs to be assembled, and for large stators, hoisting equipment is required.

[0003] Currently, there are many types of stator hoisting fixtures, including direct hoisting with ropes and horizontal hoisting with crossbars. Direct hoisting with ropes is labor-intensive, has inaccurate positioning, and low work efficiency. Horizontal hoisting with crossbars provides poor protection for the stator, is prone to damaging the winding copper wires, and is inconvenient and unsafe to operate.

[0004] A Chinese patent discloses a stator lifting clamp (authorization announcement number CN211895718U). This patented technology is not only simple in structure and easy to operate, but also saves manpower, reduces manufacturing costs, is applicable to stators of different lengths, and is safe and reliable to use. However, it is prone to causing stator damage and has poor stability during the lifting process. Utility Model Content

[0005] The purpose of this utility model is to provide a novel stator assembly tooling structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel stator assembly fixture structure includes a hanger rod, with two support seats sleeved on the upper and lower ends of the outer side of the hanger rod. External threads are provided on the outer surface of the hanger rod near the inner side of the corresponding support seat. Washers and lock nuts are sleeved on the external threads inside the support seats.

[0008] As a further improvement of this utility model, a lifting ring is connected to the top of the lifting rod.

[0009] As a further improvement of this utility model: the lower end of the lifting ring is provided with a threaded head, and the inner side of the upper end of the locking nut is provided with a threaded groove, and the threaded head is engaged with the inner side of the threaded groove.

[0010] As a further improvement of this utility model, the support base is a component made of polytetrafluoroethylene.

[0011] As a further improvement of this utility model: both of the support seats are hollow structures, and the corresponding locking nuts and washers are located inside the hollow structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model uses a lifting ring, locking nut, washer, lifting rod and two support bases to fix and lift the stator. It has good stability of the stator, high success rate, little damage to the stator, high work efficiency, and is convenient and quick to assemble and disassemble. Attached Figure Description

[0018] Please see Figures 1-3 In this embodiment of the utility model, a novel stator assembly fixture structure includes a lifting rod 5. The lifting rod 5 has two support seats 4 sleeved on its outer upper and lower ends. External threads 6 are provided on the outer surface of the lifting rod 5 near the inner side of the corresponding support seats 4. Washers 3 and locking nuts 2 are sleeved on the external threads 6 inside the support seats 4. The stator 7 to be lifted can be fixed to the lifting rod 5 by the two support seats 4. By engaging the locking nuts 2 at different positions on the external threads 6, the stator 7 can be limited. A lifting ring 1 is connected to the top of the lifting rod 5. By hanging the lifting ring 1 on an external lifting device, the locked stator 7 can be lifted.

[0019] exist Figure 2 In the process, the lower end of the lifting ring 1 is provided with a threaded head 11, and the inner side of the upper end of the locking nut 2 is provided with a threaded groove 21. The threaded head 11 is engaged with the inner side of the threaded groove 21. The lifting ring 1 and the locking nut 2 are fixedly connected together by the threaded head 11 and the threaded groove 21. After the lifting ring 1 is removed, the locking nut 2 is unscrewed counterclockwise. Then, the washer 3 and the upper support seat 4 are removed from the lifting rod 5. The stator 7 to be lifted can then be installed on the lifting rod 5. At the same time, the lower end of the stator 7 is supported by the lower support seat 4.

[0020] Preferably, the support base 4 is a component made of polytetrafluoroethylene, which can prevent scratches on the stator 7 during the process of fixing the stator 7.

[0021] exist Figure 1 and Figure 2 In the middle, both support bases 4 are hollow structures, and the corresponding locking nuts 2 and washers 3 are located inside the hollow structures, so that the locking nuts 2 and washers 3 will not come into contact with the stator 7 to be hoisted, thus protecting the stator 7 from damage.

[0022] The working principle of this utility model is as follows: When it is necessary to hoist the stator 7, firstly, a support seat 4 is fitted onto the lower end of the hoisting rod 5, then the corresponding gasket 3 is fitted onto the lower end of the hoisting rod 5, and then the locking nut 2 is tightened clockwise onto the external thread 6 located at the lower end of the hoisting rod 5.

[0023] Next, rotate the lifting ring 1 counterclockwise to remove it from the locking nut 2. Then, remove the locking nut 2, washer 3, and support 4 located at the upper end of the lifting rod 5. Next, place the stator 7 to be lifted onto the lifting rod 5 from the upper end. Then, install the support 4, washer 3, and locking nut 2 onto the lifting rod 5 in sequence from the upper end. Tighten the locking nut 2 clockwise onto the external thread 6 located at the upper end of the lifting rod 5, thereby securely fixing the stator 7 to the lifting rod 5 through the two support nut 4. Finally, tighten the threaded end 11 clockwise into the threaded groove 21, thus securely installing the stator 7 onto the lifting rod 5. Figure 3 As shown, the locked stator 7 can be hoisted by hanging it on the lifting ring 1 using external lifting equipment. This method has a high success rate, causes little damage to the stator 7, and has high work efficiency.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
