Description

Technical Field

[0001] The utility model relates to the technical field of generator stator shaping, in particular to a shaping tooling for the end part of a generator stator. Background Art

[0002] A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery to convert the energy generated by the flow of water, air flow, fuel combustion into mechanical energy and transmit it to the generator, and then the generator converts it into electrical energy. One of the cores of the generator is the stator assembly that finally generates electrical energy. With the increasing requirement for the density of generators, it is necessary to control the end part of the stator with large variables.

[0003] In the prior art, manual control is generally adopted, and the size of the end part is controlled by the proficiency of employees, resulting in multiple variations among different people and unable to achieve unity. Secondly, there are also the following problems: 1. The height of some stator points cannot be effectively controlled, resulting in problems in the internal cooperation of the generator; 2. The concentricity between the end part of the stator and the iron core cannot be guaranteed, and it is easy to scratch with accessories such as fans, affecting the quality; 3. The inspection difficulty is relatively large, and problems cannot be found in a timely and effective manner, resulting in unqualified products being easily passed to the next process, affecting subsequent production.

[0004] To solve the above problems, the utility model provides a shaping tooling for the end part of a generator stator. Content of the Utility Model

[0005] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to provide a shaping tooling for the end part of a generator stator to solve the above problems.

[0006] To achieve this purpose, the utility model adopts the following technical solutions: A shaping tooling for the end part of a generator stator provided by the utility model includes a tooling base, and a shaping plate capable of rotating along the center of the tooling base is arranged above the tooling base. A "冂"-shaped shaping groove is arranged in the downward direction of the shaping plate;

[0007] The tooling base includes an upper base and a lower base formed by cylindrical splicing. The diameter of the upper base is 1 - 2 mm larger than the inner diameter of the stator, and the diameter of the lower base is 1 - 2 mm smaller than the inner diameter of the stator.

[0008] Furthermore, the shaping plate is installed on a mandrel, and the mandrel is rotationally sleeved at the center of the tooling base.

[0009] Furthermore, the shaping plate and the mandrel are locked tightly through fixing bolts of the shaping plate.

[0010] Furthermore, a bearing mounting hole is provided at the center of the tooling base, a bearing is fixedly installed in the bearing mounting hole, the core shaft is inserted into the bearing and then snapped into the tooling base, and then the core shaft is limited on the tooling base by a core shaft fixing bolt.

[0011] Furthermore, the bottom of the lower base is provided with an arc-shaped opening that bends inwards.

[0012] Furthermore, during assembly, the end of the stator is sleeved in the shaping groove of the shaping plate, and the tooling base is sleeved in the interior of the stator core.

[0013] The beneficial effects of the utility model are:

[0014] The utility model inserts the tooling base into the inside of the stator with repairing belt and cooperates with the stator, so as to detect the concentricity between the stator and the tooling base, ensure that the concentricity of the stator is up to standard, and the stator end after the tooling detection can also ensure the concentricity with the stator; by arranging the shaping groove on the shaping plate, the problem of the stator end being too high and the diameter being too large can be effectively avoided, and the shaping plate has a simple structure and is easy to replace, which is conducive to the detection of stator ends of different sizes; at the same time, the detection result of the scheme can be directly obtained, which has the effect of convenient detection and clear results, and can directly screen out unqualified products, with good use effect.

[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0022] like Figures 1 to 3As shown, a shaping tooling for the end part of a generator stator provided in this embodiment includes a tooling base 1. Above the tooling base 1, there is a shaping plate 3 that can rotate along the center of the tooling base 1. The overall shape of the shaping plate 3 is rectangular. Among them, when the tooling base 1 is used, it is clamped into the stator and cooperates with it, mainly to ensure the concentricity of the stator, and it can ensure that the concentricity of the whole section after being sleeved can be maintained. For details, see Figure 4 , on the downward direction of the shaping plate 3, there is a "冂"-shaped shaping groove 31. The shaping groove 31 is a rectangular groove arranged below the shaping plate 3. The shaping groove 31 is mainly used to avoid the problems of excessive height and diameter of the stator end part, and it can be directly observed; the tooling base 1 includes an upper base 11 and a lower base 12 formed by cylindrical splicing. The diameter of the upper base 11 is 1-2 mm larger than the inner diameter of the stator, and the diameter of the lower base 12 is 1-2 mm smaller than the inner diameter of the stator. This setting method is convenient for the stator to be sleeved and forms a clamping position at the stator end 7 and the stator core 8,

[0023] For details, see Figure 1 , the shaping plate 3 is installed on the core shaft 2. The core shaft 2 is rotatably sleeved at the center of the tooling base 1. At the same time, the shaping plate 3 and the core shaft 2 are locked by a shaping plate fixing bolt 4. Since it is fixed by a threaded method, it is more convenient to disassemble and install the shaping plate 3, so it is also convenient to replace. When applying it to the detection of stators of larger or smaller sizes, the shaping plate 3 with a suitable detection size can be replaced accordingly, so the applicability is stronger.

[0024] For details, see Figure 2 , in order to achieve the effect that the shaping plate 3 and the core shaft 2 can rotate on the tooling chassis 1, a bearing installation hole is provided at the center of the tooling base 1. A bearing 5 is fixedly installed in the bearing installation hole. After the core shaft 2 is sleeved into the bearing 5, it is clamped into the tooling base 1, and then the core shaft 2 is limited on the tooling base 1 by a core shaft fixing bolt 6. It should be noted that the core shaft fixing bolt 6 here does not lock, fix, and immobilize the core shaft 2 and the tooling base 1, but clamps the core shaft 2 and the tooling base 1 by slightly screwing to achieve a limiting effect. At this time, the core shaft 2 can rotate in the bearing 5.

[0025] For details, see the attached drawings. The bottom of the lower base 12 is provided with an inwardly curved arc-shaped opening. The arc-shaped opening is provided to facilitate the insertion of the stator end 7.

[0026] For details, see the attached Figure 4 , during assembly, the stator end 7 is sleeved in the shaping groove 31 of the shaping plate 3, and the tooling base 1 is sleeved inside the stator core 8, so as to realize the concentricity detection of the stator end 7 and the stator core 8 and reduce the scratching situation after product assembly.

[0027] During use of the utility model, the tool is inserted into the stator to be repaired, and the concentricity of the stator end is determined by the cooperation between the tool base, the shaping groove of the shaping plate and the stator end. The stator end subsequently inspected by the tool can also ensure the concentricity with the stator, and a unified standard can be achieved. At the same time, the fixed size of the shaping groove can be used to avoid the problem of customized end being too high and the diameter being too large. The diameters of the upper base and the lower base are set to different sizes, which can achieve the effect of stator height control and reduce the problem of internal coordination of the generator.

The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
