[0038] Further, by Figure 1As shown, in this embodiment, the belt conveyor 1 is used to convey the motor metal shell to be heated, the heating chassis 2 is fixed to the top of the belt conveyor 1, the induction heating mechanism 4 is fixed in the heating chassis 2, and the inlet and outlet 21 are processed at both ends of the heating chassis 2, the loading mechanism 3 is placed on the belt of the belt conveyor 1, and is used to support the motor metal shell to be heated. After adopting the above scheme, when in use, the motor metal shell to be heated is placed on the loading mechanism 3, and then placed together on the belt of the belt conveyor 1, and the belt conveyor 1 is started to transport the motor metal shell. When the motor metal shell After the metal shell is transferred to the heating station, it is heated by the induction heating mechanism 4. During this period, the loading mechanism 3 loaded with the motor metal shell can continue to be placed on the belt of the belt conveyor 1. After the heating is completed, the belt conveyor 1 continues to start to heat the next motor metal shell. The utility model is provided with a belt conveyor 1 and a loading mechanism 3 for conveying the motor metal shell, and uses the induction heating mechanism 4 to heat the motor metal shell. It can be heated continuously and is suitable for processing lines. When taking and placing materials, it does not affect the heating of other motor metal shells, and the production efficiency is greatly improved.

[0039] It should be noted that, in actual use, a photoelectric sensor is provided in the heating chassis 2, which is used to locate the moving position of the loading mechanism 3 to ensure that the metal shell of the motor reliably corresponds to the induction heating mechanism 4 after reaching the heating station. Among them, the photoelectric sensor is a very common sensor element, and its working principle is a well-known existing technology, which will not be elaborated in this article.

[0040] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the loading mechanism 3 includes: a loading base 31 and a support block 32, a plurality of support blocks 32 are fixed to the top surface of the loading base 31 at equal intervals along the circumferential direction, and a stepped groove 321 is processed on the top surface of the support block 32. After adopting the above scheme, when in use, the motor metal shell to be heated is placed in the stepped groove 321, and the design structure of the stepped groove 321 can match most motor metal shells of different diameters.

[0041] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the loading base 31 and the support block 32 are forged one-piece components with high structural strength. It should also be noted that during use, because very high heat will be generated in the metal shell of the motor, in order to avoid excessive heat transfer to the belt conveyor 1, the loading base 31 and the support block 32 should be made of heat-insulating materials, such as aluminum alloy, and heat-reflecting paint or heat-insulating paint should be sprayed on the surface of the material to achieve a heat-insulating effect.

[0042] Optionally, by Figure 1 and Figure 3As shown, in this embodiment, the induction heating mechanism 4 includes: a lifting plate 41, a copper tube coil 42 and a vertical cylinder 43. The lifting plate 41 is located in the heating chassis 2, the copper tube coil 42 is fixed to the bottom of the lifting plate 41, the vertical cylinder 43 is fixed to the top surface of the heating chassis 2, and the piston rod of the vertical cylinder 43 passes through the heating chassis 2 and is fixedly connected to the lifting plate 41. After adopting the above scheme, when in use, when the motor metal shell reaches the heating station, the vertical cylinder 43 is started, and the vertical cylinder 43 pushes the lifting plate 41 downward, so that the copper tube coil 42 is inserted into the motor metal shell. The copper tube coil 42 is energized, and induced eddy currents are generated inside it. The eddy currents generate a large amount of heat energy inside the motor metal shell, thereby realizing rapid heating of the motor metal shell.

[0043] It should be noted that the above scheme is only an exemplary scheme of the present invention and is not used to limit the present invention. According to "Faraday's Law of Electromagnetic Induction", the copper tube coil 42 can still achieve the induction heating function by being mounted on the metal shell of the motor. Therefore, if the size of the copper tube coil 42 is large enough, it can also be mounted on the metal shell of the motor.

[0044] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the induction heating mechanism 4 also includes: guide columns 44, two guide columns 44 are symmetrically fixed on the top surface of the lifting plate 41, and the guide columns 44 pass through the heating chassis 2. After adopting the above scheme, when in use, the two guide columns 44 are used to guide the lifting plate 41, thereby improving the stability of the lifting plate 41.

[0045] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, it also includes: a limiting belt 5, two limiting belts 5 are symmetrically fixed on the belt of the belt conveyor 1, the loading mechanism 3 is located on the inner side of the two limiting belts 5, and the spacing between the two limiting belts 5 is equal to the length of the loading base 31, and the setting of the limiting belt 5 is used to guide the loading mechanism 3 to prevent the loading mechanism 3 from deviating from the induction heating mechanism 4.

[0048] It should be noted that after multiple loading bases 31 are spliced ​​end to end, the same number of copper tube coils 42 need to be set. Multiple copper tube coils 42 can be fixed at the bottom of the same lifting plate 41 at the same time and driven synchronously by the same vertical cylinder 43.

[0049] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the thickness of the splicing block 33 is half the thickness of the loading base 31. Therefore, after multiple loading bases 31 are spliced ​​end to end, the top surface of the loading base 31 is flush, and the bottom surface of the loading base 31 is flush and fits the belt of the belt conveyor 1, ensuring the stability of the loading base 31.

Those skilled in the art can make conventional selections based on usage needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed by the prior art, so they will not be elaborated on in this article.

[0052] Components not described in detail herein are prior art.

[0053] The working principle and use process of the utility model: When the heating device of the utility model is used, the motor metal shell to be heated is placed in the stepped groove 321. The design structure of the stepped groove 321 can match most motor metal shells with different diameters, and then placed together on the belt of the belt conveyor 1;

[0054] The belt conveyor 1 is started to transport the motor metal shell. When the motor metal shell is transported to the heating station, the vertical cylinder 43 is started, and the vertical cylinder 43 pushes the lifting plate 41 downward, so that the copper tube coil 42 is inserted into the motor metal shell. The copper tube coil 42 is energized, and induced eddy currents are generated inside the copper tube coil 42. The eddy currents generate a large amount of heat energy inside the motor metal shell, thereby achieving rapid heating of the motor metal shell.

[0055] During the heating period, the loading mechanism 3 loaded with the motor metal shell can continue to be placed on the belt of the belt conveyor 1. After the heating is completed, the belt conveyor 1 continues to start and heat the next motor metal shell;

[0056] The utility model is provided with a belt conveyor 1 and a loading mechanism 3 for conveying the metal shell of the motor, and uses an induction heating mechanism 4 to heat the metal shell of the motor, which can be heated continuously and is suitable for a processing line.
