When the stator and the shell are heated and the stator is naturally separated from the shell under the action of gravity, the support member is moved along the guide rod in the vertical direction by the gravity of the stator, so that the stator is disengaged from the shell along the vertical direction, reducing the damage caused by the stator deviating from the vertical direction when the stator is separated from the shell and causing local uneven force; the elastic member is elastically connected to the support member to enable the support member to move smoothly, reducing the impact force on the stator during the falling process, so as to achieve the effect of reducing the damage to the stator when it is separated from the shell.

[0007] In a possible implementation, the stator disassembly tool further includes a bottom plate, which is disposed on a side of the support member away from the fixed plate, and one end of the guide rod is fixedly connected to the fixed plate, and the other end is detachably connected to the bottom plate.

[0008] In a possible implementation manner, the elastic member is elastically supported between the bottom plate and the support member.

[0010] In a possible implementation, the support member includes a support plate and a support tray, the support plate is movably connected to the guide rod along the vertical direction, the support tray is fixedly connected to the support plate, and the support tray is used to support the stator.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] 1. The stator disassembly tool fixes the shell through a fixing plate and supports the stator through a support member. When the stator and the shell are heated and the stator is naturally separated from the shell under the action of gravity, the support member is moved along the guide rod in the vertical direction by the gravity of the stator, so that the stator is separated from the shell in the vertical direction, reducing the stator from deviating from the vertical direction when the stator is separated from the shell and being damaged by uneven local force; the elastic member is elastically connected to the support member to enable the support member to move smoothly, reducing the impact force on the stator during the falling process, so as to achieve the effect of reducing the damage to the stator when it is separated from the shell;

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0026] Example

[0027] See also Figures 1 to 4As shown, the present embodiment provides a stator disassembly tool 1 for assisting in disassembling a stator 3 contained in a housing 2. The stator disassembly tool 1 includes a fixing member 11, a guide member 12, and a support assembly 13. The fixing member 11 includes a fixing plate 111, and the fixing plate 111 is fixedly connected to the housing 2. The guide member 12 includes a guide rod 121, and the guide rod 121 is fixedly connected to the fixing plate 111 along a vertical direction 15. The support assembly 13 includes a support member 131 and an elastic member 137. The support member 131 corresponds to the stator 3 to support the stator 3. The support member 131 is movably arranged on the guide rod 121 along the vertical direction 15. The elastic member 137 is elastically connected to the support member 131. When the stator 3 is separated from the housing 2, the elastic member 137 is used to buffer the support member 131.

[0028] During the manufacturing process, the stator 3 is assembled into the shell 2 along the vertical direction 15. When the stator 3 needs to be disassembled, the stator disassembly tool 1 provided in this embodiment fixes the shell 2 by the fixing plate 111 and supports the stator 3 by the support member 131. When the stator 3 and the shell 2 are heated and the stator 3 is naturally separated from the shell 2 under the action of gravity, the support member 131 is moved along the guide rod 121 in the vertical direction 15 by the gravity of the stator 3, so that the stator 3 is separated from the shell 2 along the vertical direction 15, thereby reducing the stator 3 from deviating from the vertical direction 15 when the stator 3 is separated from the shell 2 and being damaged by uneven local force; the elastic member 137 is elastically connected to the support member 131 to enable the support member 131 to move smoothly, reduce the impact force on the stator 3 during the falling process, and reduce the damage to the stator 3 when it is separated from the shell 2.

[0029] The end surface of the housing 2 in contact with the fixing plate 111 has a threaded hole, and the fixing plate 111 has a long strip through hole 112, and bolts are arranged in the through hole 112 to fix the housing 2 and the fixing plate 111. There are multiple through holes 112, and the multiple through holes 112 are arranged at intervals, so that the bolts are arranged at appropriate positions of the fixing plate 111, so that the bolts are fixedly connected to housings 2 of different shapes.

[0030] In a possible implementation, the stator disassembly tool 1 further includes a bottom plate 14 , which is disposed on a side of the support member 131 away from the fixed plate 111 , and one end of the guide rod 121 is fixedly connected to the fixed plate 111 , and the other end is detachably connected to the bottom plate 14 .

[0031] In this embodiment, the bottom plate 14 , the guide rod 121 and the fixing plate 111 are interconnected and enclosed to form a frame, and the housing 2 and the stator 3 are accommodated in the frame. Such an arrangement facilitates the disassembly of the stator tool 1 to move the housing 2 and the stator 3 .

[0032] Please combine Figure 3As shown, when the stator disassembly tool 1 is used, the fixing plate 111 is first placed on the ground, and then the housing 2 is placed on the fixing plate 111 and fixedly connected to the fixing plate 111, and then the support member 131 is moved along the guide rod 121 to a position in contact with the stator 3, and then the bottom plate 14 is fixedly connected to the guide rod 121, and finally the stator disassembly tool 1 is turned over. Figure 4 As shown, the fixing plate 111 is kept away from the ground and the bottom plate 14 is kept close to the ground. The shell 2 and the stator 3 in the stator disassembly tool 1 are heated by heating. Since the expansion coefficients of the shell 2 and the stator 3 are different, the expansion amount of the shell 2 is greater than the expansion amount of the stator 3 during the heating process of the shell 2 and the stator 3, so that the stator 3 is naturally separated from the shell 2 under the action of gravity. In the process of the stator 3 being separated from the shell 2, the support member 131 moves along the guide rod 121 under the gravity of the stator 3, and the elastic member 137 is elastically connected to the support member 131 to enable the support member 131 to move smoothly, reduce the impact on the stator 3 during the falling process, and reduce the damage to the stator 3 when it is separated from the shell 2, so that the stator 3 can be taken out intact.

[0033] In a possible implementation manner, the elastic member 137 is elastically supported between the bottom plate 14 and the support member 131 .

[0034] In this embodiment, the elastic member 137 is a spring, one end of which is connected to the bottom plate 14 and the other end is connected to the support member 131. When the support member 131 moves along the guide rod 121 under the gravity of the stator 3, the support member 131 compresses the elastic member 137, and the elastic member 137 elastically contracts to buffer the support member 131, so that the support member 131 falls smoothly, reducing the impact of the stator 3 when it is separated from the housing 2, so that the stator 3 can be taken out intact. The elastic member 137 can also be an elastic damper, an elastic rope or an elastic plate, etc., so as to buffer the support member 131, and the present application is not limited thereto.

[0035] In a possible implementation, the elastic member 137 is connected between the fixing plate 111 and the supporting member 131. The present application is not limited to the configuration of the elastic member 137.

[0036] In this embodiment, one end of the elastic member 137 is connected to the fixing plate 111, and the other end is connected to the support member 131. When the support member 131 moves along the guide rod 121 under the gravity of the stator 3, the support member 131 stretches the elastic member 137, and the elastic member 137 stretches elastically to cushion the support member 131, so that the support member 131 falls smoothly, reducing the impact of the stator 3 when it is separated from the housing 2, so that the stator 3 can be taken out intact.

[0037] In a possible implementation, the support member 131 includes a support plate 132 and a support tray 133 . The support plate 132 is movably connected to the guide rod 121 along the vertical direction 15 . The support tray 133 is fixedly connected to the support plate 132 . The support tray 133 is used to support the stator 3 .

[0038] In a possible embodiment, the support tray 133 includes an annular wall 134 and a bottom wall 136. The bottom wall 136 is fixedly connected to the support plate 132 by screws. The annular wall 134 is connected to the bottom wall 136. The annular wall 134 protrudes toward the stator 3. The annular wall 134 is used to support the end face of the stator 3. The annular wall 134 is provided with a notch 135, and the notch 135 is used to remove the stator 3.

[0039] In this embodiment, since the geometric center of the stator 3 is inconsistent with the center of gravity, the stator 3 is unbalanced during the separation from the housing 2, and the stator 3 may roll over. The stator disassembly tool 1 supports the stator 3 through the support tray 133. The annular wall 134 of the support tray 133 protrudes toward the stator 3. The annular wall 134 supports the end face of the stator 3, so that the annular wall 134 stably supports the stator 3 to reduce damage to the stator 3 when it is separated from the housing 2.

[0040] The annular wall 134 is connected to the bottom wall 136 and encloses a receiving cavity. The end face of the stator 3 corresponds to the annular wall 134. The wires and other structures in the stator 3 protrude into the receiving cavity, so that the end face of the stator 3 fits the annular wall 134, so that the annular wall 134 can stably support the stator 3.

[0041] When the support member 131 drops to a position close to the bottom plate 14 , the stator 3 moves out of the support tray 133 through the notch 135 to reduce the risk of damage to the stator 3 caused by collision when the stator 3 is separated from the housing 2 .

[0042] In a possible implementation, the fixing member 11 further includes a pressing plate 113 and a pressing rod 114 . The pressing plate 113 and the pressing rod 114 are arranged opposite to each other, and the pressing plate 113 and the pressing rod 114 are movably connected to the guide rod 121 along the vertical direction 15 .

[0043] In a possible implementation, the guide rod 121 includes a first rod 122, a second rod 123, a third rod 124 and a fourth rod 125 that are arranged at intervals, one end of the pressure plate 113 is arranged on the first rod 122 and the other end is arranged on the second rod 123, and the pressure rod 114 is arranged on the third rod 124 or the fourth rod 125.

[0044] In this embodiment, the pressing plate 113 and the pressing rod 114 are used to press the housing 2 against the fixing plate 111 so that the housing 2 is stably fixed to the fixing plate 111 to reduce the displacement of the housing 2 and damage to the stator 3 when the stator 3 is separated from the housing 2 .

[0045] In summary, the stator disassembly tool 1 fixes the housing 2 through the fixing plate 111, and supports the stator 3 through the support member 131. When the stator 3 and the housing 2 are heated and the stator 3 is naturally separated from the housing 2 under the action of gravity, the support member 131 moves along the guide rod 121 in the vertical direction 15 under the gravity of the stator 3, and the elastic member 137 is elastically connected to the support member 131 to make the support member 131 move smoothly, so as to reduce the damage of the stator 3 when it is separated from the housing 2. Since the geometric center of the stator 3 is inconsistent with the center of gravity, the stator 3 is unbalanced during the separation from the housing 2, and the stator 3 may roll over. The stator disassembly tool 1 supports the stator 3 through the support tray 133, and the annular wall 134 of the support tray 133 protrudes toward the stator 3. The annular wall 134 is used to support the end face of the stator 3, so that the annular wall 134 stably supports the stator 3, so as to reduce the damage of the stator 3 when it is separated from the housing 2.

[0046] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
