[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a motor stator flipping device, including a support column 1, a base 2 and an inner support plate 3, the base 2 is a cross-shaped structure, the base 2 is fixed to one end of the support column 1, and a plurality of limiting steps 23 are provided on one side of the base 2 close to the support column 1, and the distance between each limiting step 23 and the support column 1 matches the outer circle radius of the motor stator;

[0036] The other end of the support column 1 is provided with a threaded hole, and the support column 1 is threadedly connected with a lifting ring;

[0037] The inner support plate 3 is a circular ring structure, the inner diameter of the inner support plate 3 matches the support column 1, the outer diameter of the inner support plate 3 matches the inner diameter of the motor stator, and the inner support plate 3 is coaxially fixed on the outside of the support column 1.

[0038] Working principle: The rotor is in a horizontal state, and the horizontal flip device is moved to make the support column 1 pass through the inner hole of the motor stator. The inner support plate 3 cooperates with the inner hole of the motor stator to support the motor stator. When one end of the motor stator contacts the limit step 23 on the base 2, the installation of the motor stator is completed. The lifting device is connected to the lifting ring at one end of the support column 1, and the two contact points of the base 2 and the ground are used as fulcrums. The lifting structure lifts the support column 1, the flip device stands up, and the motor stator is in a vertical state to complete the flip.

[0039] This solution moves the horizontally placed flipping device so that the support column 1 passes through the inner hole of the motor stator, and the inner support plate 3 cooperates with the inner hole of the motor stator to support the motor stator, so that one end of the motor stator contacts the limit step 23 for positioning support. Then, the lifting ring at one end of the support column 1 is connected by a lifting device, and the support column 1 is lifted with the two contact points of the base 2 and the ground as fulcrums, so that the motor stator changes from a horizontal state to a vertical state, completing the flipping.

[0040] The inner support plate 3 cooperates with the limiting step 23 on the base 2 to reliably limit and fix the motor stator, ensuring the safety of the motor stator during the flipping process. The flipping device has a simple structure, low cost and convenient later maintenance. The cross-shaped base has a small footprint and is easy to transfer. In the flipping process, the support column 1 is inserted into the inner hole of the stator, and there is no need to manually move the motor stator, which improves the efficiency of the flipping and reduces the labor intensity.

[0041] As a preferred implementation mode, Figure 3 As shown, the inner support plate 3 includes a support circular plate 31 and a nylon ring 32;

[0042] The supporting circular plate 31 is a circular ring structure and is coaxially fixed on the outside of the supporting column 1 . The outer diameter of the nylon ring 32 is larger than the outer diameter of the supporting circular plate 31 and the nylon ring 32 is coaxially fixed on the supporting circular plate 31 .

[0043] In this solution, the inner support plate 3 adopts a splicing mechanism of a support circular plate 31 and a nylon ring 32. The outer diameter of the nylon ring 32 is larger than the outer diameter of the support circular plate 31. The nylon ring 32 contacts the inner ring of the motor stator, so that the inner support plate 3 is in soft contact with the inner ring of the motor stator to avoid the motor stator from being injured when it is turned over, play a protective role, and protect the safety of the inner ring of the motor stator.

[0044] Furthermore, the nylon ring 32 is located on a side of the supporting circular plate 31 away from the base 2 .

[0045] Taking into account that the nylon ring 32 and the inner ring of the motor stator are in interference fit, and the nylon ring 32 is made of soft material and will deform, the nylon ring 32 is set on the side of the supporting circular plate 31 away from the base. When the flipping device is moved, the nylon ring 32 enters the inner ring of the motor stator and bends toward the supporting circular ring 31, which can better protect the inner ring of the motor stator.

[0046] Furthermore, there are multiple inner support plates 3 .

[0047] A plurality of inner support plates 3 are arranged on the support column 1, that is, there are a plurality of supports in the inner ring of the motor stator, to ensure the stability of the motor stator flipping process and improve reliability and safety. Optionally, in this embodiment, two inner support plates 3 are arranged in parallel on the outer side of the support column 1.

[0048] Specifically, bolt holes are provided at corresponding positions of the supporting circular plate 31 and the nylon ring 32 , and the nylon ring 32 is bolted to the supporting circular plate 31 .

[0049] As another preferred implementation, Figure 1 and Figure 4 As shown, a triangular rib plate 33 is provided between the supporting circular plate 31 and the supporting column 1 , one side of the rib plate 33 is connected to the supporting column 1 , and the adjacent side is connected to the supporting circular plate 31 . There are multiple rib plates 33 , and the rib plates 33 are symmetrically distributed.

[0050] Furthermore, a plurality of through holes 34 are provided on the supporting circular plate 31 , and each through hole 34 is distributed in a circular array.

[0051] During the turning process of the motor stator, the inner support plate 3 will be subjected to pressure from multiple directions of the motor stator. By setting multiple ribs 33 between the inner support plate 3 and the support column 1, the support capacity of the inner support plate 3 is improved and the service life of the device is extended. On the other hand, by setting multiple through holes 34 on the supporting circular plate 31, the weight of the device is reduced, the transfer is convenient, and the conditions on both sides of the stator can be observed through the through holes 34. One of the support plates is set at the center of gravity of the turning structure, so that the through hole cooperates with the hook of the lifting structure, and the lifting structure lifts the turning device through the through hole 34 and transfers it.

[0052] Specifically, the base 2 includes a first U-shaped plate 21 and a second U-shaped plate 22 that are perpendicular to each other. The first U-shaped plate 21 and the second U-shaped plate 22 are clamped together, and the limiting steps 23 are symmetrically arranged at one end of the first U-shaped plate 21 and the second U-shaped plate 22 .

[0053] The first U-shaped plate 21 and the second U-shaped plate 22 have the same length, and the length is recorded as L. The outer diameter of the motor stator is recorded as D. The lengths of the first U-shaped plate 21 and the second U-shaped plate 22 satisfy: L>D and

[0054] When the support column 1 is inserted into the inner ring of the motor stator, the cross structure base 1 will not interfere with the installation process due to its excessive length, and a limiting step 23 can be provided to reliably support the motor stator.

[0055] A welding plate 4 is provided between the support column 1 and the base 2. The diameter of the welding plate 4 is larger than the diameter of the support column 1. One end of the welding plate 4 is connected to the support column 1, and the other end is connected to the base 2. The welding area of ​​the base is increased, the connection between the two is ensured to be firm, and the reliability of the connection between the base 2 and the support column 1 is improved.

[0056] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
