Description

Technical Field

[0001] This application relates to the field of stator disassembly device technology, specifically to a disassembly device for disassembling stator assemblies. Background Technology

[0002] With the rapid development of the new energy vehicle industry, automakers are gradually delving into the research and development and production of key components. It is particularly important for electric drive, one of the core components of the new energy "three electrics", to be completely independently integrated and manufactured. Among them, the electric drive stator heat fitting is an important process link in electric drive assembly.

[0003] In existing technologies, after the stator assembly is heat-fitted, the stator body is embedded in the housing. However, defective stator assemblies after heat-fitting can only be disassembled by cutting the housing. After disassembly, the surface of the stator body is damaged and impurities adhere to it, making it unusable and resulting in the ineffective waste of high-value components. Therefore, how to more rationally disassemble the housing and stator body without damaging the stator body has become an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this application is to provide a disassembly device for disassembling stator assemblies, so as to solve the problem in the prior art that the stator body is not damaged after the housing and stator body are disassembled.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A disassembly device for disassembling a stator assembly, the stator assembly including a housing and a stator body, the disassembly device including: a frame, a heating mechanism, a housing fixing mechanism, and a stator support mechanism, the heating mechanism being disposed on the frame and including a heating coil, the heating coil being used to heat the housing to cause the housing to expand due to heat; the housing fixing mechanism being movably disposed on the frame, the housing being adapted to be disposed on the housing fixing mechanism; the stator support mechanism being connected to the heating mechanism and used to support the disassembled stator body.

[0007] Based on the aforementioned technical means, by setting up a heating coil, the housing can be heated to cause it to expand and separate from the stator body, thus achieving disassembly. This disassembly method can replace the existing method of cutting the housing, preventing damage to the stator body and the adhesion of impurities during cutting. The disassembly method is safe and reliable, improves disassembly quality, is convenient to operate, and can reduce material costs on the production line, avoiding waste. Simultaneously, by setting up a stator support mechanism, the stator body can be supported as it falls after disassembly, further preventing damage to the stator body.

[0008] Furthermore, the stator support mechanism includes: a limiting seat located at the top of the stator support mechanism; a first mounting plate located below the limiting seat and spaced apart from the limiting seat; and a buffer component disposed between the limiting seat and the first mounting plate.

[0009] According to the above-mentioned technical means, by setting a buffer component, the impact force when the stator body falls can be mitigated, thereby further protecting the stator body from damage. For example, the buffer component can be a through hole formed at the bottom of the limiting seat. By setting the through hole, the contact area between the stator body and the limiting seat when falling can be reduced, thereby reducing the impact force when the stator body falls and playing a buffering role.

[0010] Furthermore, the buffer component includes: a first guide rod extending in the vertical direction, one end of the first guide rod being fixedly connected to the limiting seat, and the other end of the first guide rod being movably connected to the first mounting plate in the vertical direction; and an elastic element sleeved on the outer periphery of the first guide rod.

[0011] Based on the aforementioned technical means, by incorporating an elastic element, the stator body needs to overcome the elastic force of the element during its descent. This allows the stator body to slowly descend, preventing damage due to excessive speed caused by its own weight. Furthermore, by providing a first guide rod, adaptive adjustments can be made when the stator body reaches the limiting seat. This allows the first guide rod to slide up and down on the first mounting plate, following the vertical length changes of the elastic element, thus ensuring a buffering effect.

[0012] Furthermore, the first mounting plate has a through hole for the first guide rod to pass through, and the stator support mechanism also includes a stop member connected to the first guide rod. The lower end of the stop member is located below the first mounting plate, and the cross-sectional area of ​​the stop member is larger than the cross-sectional area of ​​the lower end of the through hole.

[0013] According to the above technical means, by setting a stop, the elastic element can be locked at the lower end of the first mounting plate when it rebounds upward, so as to prevent the first guide rod from coming out of the through hole when it moves upward, thereby improving the reliability of the cooperation between the first guide rod and the first mounting plate.

[0014] Furthermore, the stator support mechanism further includes: a lifting cylinder, which is located below the first mounting plate and is used to drive the first mounting plate to move along the vertical direction; a second mounting plate, which is located below the first mounting plate and spaced apart from it, and the lifting cylinder passes through the second mounting plate; and a second guide rod, which extends along the vertical direction, with one end of the second guide rod fixedly connected to the first mounting plate and the other end of the second guide rod movably connected to the second mounting plate along the vertical direction.

[0015] According to the above technical means, by setting up a lifting cylinder, before heating begins, the lifting cylinder can lift the second mounting plate to drive the limit seat upward to contact the stator body, so that the elastic element is slightly stressed. After the housing is heated to separate from the stator body, the stator body falls to the limit seat and compresses the elastic element. To avoid excessive compression of the elastic element causing the stator body to rebound, the lifting cylinder is activated when the stator body and the limit seat descend to a preset position. The lifting cylinder can move the first mounting plate, the limit seat, and the stator body downward to relieve the compression pressure on the elastic element and further ensure the buffering effect.

[0016] Furthermore, the heating mechanism also includes: a base plate, which is placed on the frame; a third mounting plate, which is located above the base plate and spaced apart from the base plate, and the stator support mechanism is placed on the base plate and passes through the third mounting plate; and a coil fixing frame, which is supported on the third mounting plate and used to support the heating coil.

[0017] According to the above technical means, by setting a third mounting plate, it can serve as a support for the coil fixing frame and the heating coil, and at the same time, it can be used for the stator support mechanism to pass through, so that the heating coil and the stator support mechanism are coaxially arranged in the vertical direction, so that the stator body separated from the housing can fall onto the stator support mechanism, ensuring the protection effect of the stator body.

[0018] Furthermore, the disassembly device also includes multiple position adjustment mechanisms, which are spaced apart on the outer periphery of the base plate.

[0019] Based on the above technical means, by setting a position adjustment mechanism, the disassembly device can be aligned not only through the housing fixing mechanism, but also through the position adjustment mechanism, so as to ensure the disassembly accuracy of the disassembly device.

[0020] Furthermore, the housing fixing mechanism is mounted on the frame via a first moving mechanism, which is used to drive the housing fixing mechanism to move along the vertical direction.

[0021] According to the above technical means, before heating, when the stator assembly is directly above the heating coil, the first moving mechanism can drive the stator assembly downward until the heating coil extends to the radial inner side of the heating coil, so as to ensure the heating effect on the housing. After disassembly, the first moving mechanism can drive the housing upward until it extends beyond the heating coil, so that the stator body and the housing are completely separated, and the housing can be moved in other directions.

[0022] Furthermore, the housing fixing mechanism includes a first connecting plate and a second connecting plate. The first connecting plate is connected to the first moving mechanism, and the first connecting plate is detachably connected to the second connecting plate. The housing is mounted on the second connecting plate.

[0023] According to the above technical means, by setting a detachable first connecting plate and a second connecting plate, it is easy to replace the second connecting plate, so as to replace different second connecting plates according to different models of stator assemblies, thereby improving the applicability of the disassembly device.

[0024] Furthermore, the housing fixing mechanism also includes a fixing component, which is connected to the first moving mechanism. The first connecting plate is connected to the fixing component through a second moving mechanism. The heating mechanism is located on one side of the fixing component along a preset direction. The second moving mechanism is used to drive the housing to move along the preset direction.

[0025] According to the above-mentioned technical means, by setting up a second moving mechanism, the stator assembly can be moved easily, and the coaxiality of the stator assembly, heating coil and stator support mechanism can be ensured by adjusting the second moving mechanism, so as to ensure disassembly accuracy.

[0026] The beneficial effects of this application are:

[0027] (1) By setting a heating coil, the housing can be heated to expand and separate from the stator body, thus achieving disassembly. The disassembly method is safe and reliable, improves the disassembly quality, is easy to operate, and can reduce the material cost of the production line and avoid waste. (2) By setting a buffer component and a lifting cylinder, the stator body can be buffered to further improve the protection effect of the stator body and prevent damage to the stator body.

[0028] (3) By setting up a first moving mechanism, a second moving mechanism and a position adjustment mechanism, this application can facilitate the adjustment of the relative positions of the stator assembly, the heating mechanism and the stator support mechanism to ensure the disassembly accuracy of the disassembly device.

[0029] (4) By setting a detachable first connecting plate and a second connecting plate, this application can facilitate the replacement of different second connecting plates according to different models of stator assemblies, thereby improving the applicability of the disassembly device.

[0046] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0048] The following description, with reference to the accompanying drawings, describes a disassembly apparatus 100 for disassembling a stator assembly 200 according to an embodiment of this application. The disassembly apparatus 100 includes a frame 10, a heating mechanism 20, a housing fixing mechanism 30, and a stator support mechanism 40. The stator assembly 200 includes a housing 210 and a stator body 220.

[0049] Specifically, such as Figures 1-8 As shown, the heating mechanism 20 is mounted on the frame 10 and includes a heating coil 21. The heating coil 21 heats the housing 210 to cause it to expand. The housing fixing mechanism 30 is movably mounted on the frame 10, and the housing 210 is adapted to be mounted on the housing fixing mechanism 30. The stator support mechanism 40 is connected to the heating mechanism 20 and is used to support the disassembled stator body 220. It is understood that at least a portion of the stator support mechanism 40 is located below the heating coil 21 to facilitate support of the disassembled stator body 220.

[0050] After the stator assembly 200 is heat-fitted, the housing 210 and the stator body 220 will be interference-fitted, and the stator body 220 will be embedded in the housing 210. By providing a heating coil 21, the housing 210 can be heated to cause the housing 210 to expand. After the housing 210 expands, a gap will be created between the housing 210 and the stator body 220 embedded in the housing 210, causing it to loosen.

[0051] For example, such as Figure 1As shown, the frame 10 may include a column 12 and a support plate 11. The column 12 extends vertically and is connected above the support plate 11. A housing fixing mechanism 30 is movably mounted on the column 12, and a heating mechanism 20 is mounted on the support plate 11. The housing 210 is mounted on the housing fixing mechanism 30 and can be connected by bolts. Specifically, the stator body 220 is located below the housing 210, and the housing 210 is mounted below the housing fixing mechanism 30. This allows the stator body 220, which has a gap with the housing 210, to fall into the stator support mechanism 40. During heating, at least a portion of the housing 210 can extend into the radially inner side of the heating coil 21 to ensure that the heating coil 21 can more effectively heat the outer ring of the housing 210. This reduces the influence of the temperature of the heating coil 21 on the stator body 220 located radially inner side of the housing 210, thereby improving the reliability of disassembly and ensuring the reliability of the stator body 220.

[0052] Before disassembling the stator assembly 200, the housing 210 can be installed onto the housing fixing mechanism 30. At this time, the entire stator assembly 200 can move along with the housing fixing mechanism 30. The housing fixing mechanism 30 moves the stator assembly 200 to the heating coil 21. The heating coil 21 heats the housing 210, causing it to expand and creating a gap between the housing 210 and the stator body 220. The stator body 220 then moves downwards under gravity to disassemble the stator assembly 200. The stator support mechanism 40 supports the disassembled stator body 220 to prevent damage during its fall, ensuring the structural reliability of the disassembled stator body 220 and allowing it to be reused. At this time, the housing 210 is still installed on the housing fixing mechanism 30. The housing fixing mechanism 30 can drive the housing 210 to move toward the initial position so as to facilitate the loading and unloading of the stator body 220 and the housing 210. After the temperature drops, the stator body 220 and the housing 210 are taken out to complete the entire disassembly process.

[0053] The disassembly device 100 may also include a temperature sensor (not shown in the figure). The temperature sensor can be connected to and communicate with the heating mechanism 20. The temperature sensor can detect the temperature of the stator assembly 200 in real time. The heating coil 21 can reasonably set the heating temperature according to the detected temperature of the stator assembly 200 to avoid damage to the stator body 220 due to excessive temperature. It is understood that the set temperature of the temperature sensor can be specifically set according to the actual situation to be applied to the disassembly of the stator assembly 200 in various heat-fitting processes.

[0054] Therefore, by setting up the heating coil 21, the housing 210 can be heated to cause it to expand and separate from the stator body 220, thus achieving disassembly. This disassembly method can replace the existing method of cutting the housing, preventing damage to the stator body and the adhesion of impurities during cutting. The disassembly method is safe and reliable, improves disassembly quality, is convenient to operate, and can reduce material costs on the production line, avoiding waste. At the same time, by setting up the stator support mechanism 40, the stator body 220 can be supported after disassembly and falling, further preventing damage to the stator body 220.

[0055] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the stator support mechanism 40 includes a limiting seat 41, a first mounting plate 42, and a buffer component. The limiting seat 41 is located at the top of the stator support mechanism 40; the first mounting plate 42 is located below the limiting seat 41 and spaced apart from it; the buffer component is disposed between the limiting seat 41 and the first mounting plate 42. (Refer to...) Figure 4 The limiting seat 41 may have a limiting groove, which allows the stator body 220 to fall into when it descends, preventing it from shifting in the circumferential direction. Thus, by providing a buffer component, the impact force of the stator body 220 during its fall can be mitigated, further protecting it from damage. For example, the buffer component may be a through hole 411 formed at the bottom of the limiting seat 41. By providing the through hole 411, the contact area between the stator body 220 and the limiting seat 41 during its fall can be reduced, thereby reducing the impact force and providing a buffering effect.

[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, the buffer component includes a first guide rod 43 and an elastic element 44, for example, the elastic element 44 can be a spring. The first guide rod 43 extends in the vertical direction, one end of the first guide rod 43 is fixedly connected to the limiting seat 41, and the other end of the first guide rod 43 is movably connected to the first mounting plate 42 in the vertical direction. The elastic element 44 is sleeved on the outer periphery of the first guide rod 43. For example, there are multiple first guide rods 43 spaced apart, and there can be three first guide rods 43 to ensure the stability of the support for the limiting seat 41.

[0057] Therefore, by setting the elastic element 44, the stator body 220 needs to overcome the elastic force of the elastic element 44 when it falls, so that the stator body 220 can fall slowly through the elastic element 44, avoiding damage to the stator body 220 due to excessive falling speed caused by its own weight. By setting the first guide rod 43, adaptive adjustments can be made when the stator body 220 falls to the limiting seat 41, so that the first guide rod 43 can slide up and down on the first mounting plate 42 to follow the vertical length change of the elastic element 44, thus ensuring the buffering effect.

[0058] In some embodiments, such as Figure 6 As shown, the first mounting plate 42 has a through hole 421 for the first guide rod 43 to pass through. The stator support mechanism 40 also includes a stop member 45, which is connected to the first guide rod 43. The lower end of the stop member 45 is located below the first mounting plate 42, and the cross-sectional area of ​​the stop member 45 is larger than the cross-sectional area of ​​the lower end of the through hole 421. By setting the stop member 45, it can be locked at the lower end of the first mounting plate 42 when the elastic member 44 rebounds upward, preventing the first guide rod 43 from dislodging from the through hole 421 when it moves upward, thus improving the reliability of the cooperation between the first guide rod 43 and the first mounting plate 42.

[0059] like Figure 6 As shown, the stator support mechanism 40 may further include a sliding sleeve 49, which is sleeved over the lower end of the first guide rod 43. The two ends of the sliding sleeve 49 can respectively abut against the lower section of the elastic member 44 and the upper end of the first mounting plate 42. The first guide rod 43 is movably disposed within the sliding sleeve 49 in the vertical direction. By providing the sliding sleeve 49, on the one hand, the smoothness of the sliding of the first guide rod 43 can be improved; on the other hand, the reliability of the cooperation with the elastic member 44 can be improved, ensuring the elastic force of the elastic member 44 and improving the compression effect of the elastic member 44, so as to further prevent the stator body 220 from being damaged.

[0060] In some embodiments, such as Figure 5 As shown, the stator support mechanism 40 also includes a lifting cylinder 46, a second mounting plate 47, and a second guide rod 48. The lifting cylinder 46 is located below the first mounting plate 42 and is used to drive the first mounting plate 42 to move in the vertical direction. The second mounting plate 47 is located below the first mounting plate 42 and is spaced apart from the first mounting plate 42. The lifting cylinder 46 passes through the second mounting plate 47. The second guide rod 48 extends in the vertical direction. One end of the second guide rod 48 is fixedly connected to the first mounting plate 42, and the other end of the second guide rod 48 is movably connected to the second mounting plate 47 in the vertical direction.

[0061] For example, multiple second guide rods 48 can be spaced apart, and there can be three second guide rods 48, to ensure the support effect on the first mounting plate 42. By setting the second guide rods 48, adaptive adjustments can be made when the stator body 220 falls, so that the second guide rods 48 can slide up and down on the second mounting plate 47 following the length change of the elastic element 44 in the vertical direction, so as to ensure the buffering effect.

[0062] Therefore, by setting up a lifting cylinder 46, before heating begins, the lifting cylinder 46 can lift the first mounting plate 42 to drive the limiting seat 41 upward to contact the stator body 220, so that the elastic element 44 is slightly stressed. After the heating housing 210 separates from the stator body 220, the stator body 220 falls to the limiting seat 41 and compresses the elastic element 44. To avoid the stator body 220 rebounding due to excessive compression of the elastic element 44, the lifting cylinder 46 is activated when the stator body 220 and the limiting seat 41 descend to the preset position. The lifting cylinder 46 can move the first mounting plate 42, the limiting seat 41 and the stator body 220 downward to relieve the compression pressure of the elastic element 44 and further ensure the buffering effect.

[0063] In some embodiments, such as Figure 7 As shown, the heating mechanism 20 also includes a base plate 22, a third mounting plate 23, and a coil fixing bracket 24. The base plate 22 is placed on the frame 10, and the third mounting plate 23 is located above the base plate 22 and spaced apart from it. For example, the third mounting plate 23 can be supported by a support column. The stator support mechanism 40 is placed on the base plate 22 and passes through the third mounting plate 23. The coil fixing bracket 24 is supported on the third mounting plate 23 and is used to support the heating coil 21. For example, the coil fixing bracket 24 can be made of non-metallic material to prevent heat from being transferred to other locations through the coil fixing bracket 24, thereby improving the heating efficiency and effect on the housing 210.

[0064] Therefore, by setting the third mounting plate 23, it can serve to support the coil fixing frame 24 and the heating coil 21, and at the same time, it can allow the stator support mechanism 40 to pass through, so that the heating coil 21 and the stator support mechanism 40 are coaxially arranged in the vertical direction, so that the stator body 220 separated from the housing 210 can fall onto the stator support mechanism 40, ensuring the protection of the stator body 220.

[0065] In some embodiments, such as Figure 7As shown, the disassembly device 100 may further include multiple position adjustment mechanisms 50, which are spaced apart on the outer periphery of the base plate 22. For example, the base plate 22 may be constructed as a polygon, and each edge of the base plate 22 may be provided with at least one position adjustment mechanism 50 to adjust the position of the heating mechanism 20 in the front-back and left-right directions. Thus, by providing position adjustment mechanisms 50, the disassembly device 100 can be aligned not only by the housing fixing mechanism 30 but also by the position adjustment mechanisms 50, thereby ensuring the disassembly accuracy of the disassembly device 100.

[0066] Furthermore, the stator support mechanism 40 can be placed on the base plate 22. The coaxiality of the stator support mechanism 40 relative to the stator body 220 can also be adjusted by the position adjustment mechanism 50 to ensure the support and protection effect on the stator body 220.

[0067] In some embodiments, such as Figure 3 As shown, the housing fixing mechanism 30 is mounted on the frame 10 via a first moving mechanism 60, which drives the housing fixing mechanism 30 to move vertically. By setting the first moving mechanism 60, before heating, when the stator assembly 200 is directly above the heating coil 21, the first moving mechanism 60 can drive the stator assembly 200 downwards until the heating coil 21 extends radially inwards, ensuring effective heating of the housing 210. After disassembly, the first moving mechanism 60 can drive the housing 210 upwards until it extends beyond the heating coil 21, completely separating the stator body 220 and the housing 210, and facilitating movement of the housing 210 in other directions.

[0068] In some embodiments, such as Figure 3 and Figure 4 As shown, the housing fixing mechanism 30 includes a first connecting plate 31 and a second connecting plate 32. The first connecting plate 31 is connected to the first moving mechanism 60. This connection can be direct or indirect, and is not limited here. The first connecting plate 31 and the second connecting plate 32 are detachably connected, and the housing 210 is mounted on the second connecting plate 32. For example, the first connecting plate 31 and the second connecting plate 32 are connected via grippers 70. By providing a detachably connected first connecting plate 31 and second connecting plate 32, it is convenient to replace the second connecting plate 32, allowing for the replacement of different second connecting plates 32 according to different models of stator assemblies 200, thereby improving the applicability of the disassembly device 100.

[0069] For example, the second connecting plate 32 may have a plurality of spaced-apart positioning holes 321 and a plurality of spaced-apart positioning pins 322. The positioning pins 322 are located below the second connecting plate 32 and may be screws. The positioning pins 322 are used to mount the housing 210 of the stator assembly 200. The positioning pins 322 may include round pins and diamond pins to prevent jamming during loading and unloading of the stator assembly 200. The first connecting plate 31 may have a positioning element (not shown in the figure), which engages with the positioning holes 321 to achieve positioning and mounting of the first connecting plate 31 and the second connecting plate 32.

[0070] In some embodiments, such as Figure 1 As shown, the housing fixing mechanism 30 also includes a fixing component 33, which is connected to the first moving mechanism 60. The first connecting plate 31 is connected to the fixing component 33 via a second moving mechanism (not shown). The heating mechanism 20 is located on one side of the fixing component 33 along a preset direction. The second moving mechanism is used to drive the housing 210 to move along the preset direction. Thus, by setting the second moving mechanism, the stator assembly 200 can be moved easily, and the coaxiality of the stator assembly 200, the heating coil 21, and the stator support mechanism 40 can be ensured by adjusting the second moving mechanism, thereby ensuring disassembly accuracy.
