Description

Technical Field

[0001] This invention relates to the field of motor stator manufacturing technology, and more specifically, to a device for separating the stator housing from the inner support assembly. Background Technology

[0002] During the assembly of the motor stator, in order to fix the magnets to the inner wall of the stator housing, an internal support assembly is usually required to hold the magnets, which need to be glued to the inner wall of the stator housing, so as to facilitate the subsequent curing process. Therefore, after curing, it is also necessary to separate the internal support assembly from the stator housing. This is a key step in the stator assembly process. However, the traditional disassembly method mostly uses manual disassembly. Manual disassembly is not only labor-intensive and inefficient, but it is also difficult to control the magnitude and direction of the disassembly force. Uneven force can easily damage the internal support assembly, stator housing, or magnets, significantly affecting product quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for separating the stator housing and the inner support assembly, in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: This invention provides a device for separating a stator housing from an inner support assembly, including a frame, on which a linear conveying mechanism and a lifting drive mechanism are provided, the lifting drive mechanism being located above the linear conveying mechanism; the output end of the lifting drive mechanism is provided with a lifting platform, the bottom surface of which is respectively provided with an inner support assembly pressing head and a stator housing pressing head, the inner support assembly pressing head and the stator housing pressing head being distributed sequentially at intervals along the conveying direction of the linear conveying mechanism; the output end of the linear conveying mechanism is provided with a fixture to drive the fixture to move back and forth between the inner support assembly pressing head and the stator housing pressing head; the top of the fixture is provided with a platform supporting the inner support assembly; the outer peripheral sidewall of the fixture is provided with a recess to avoid the downward movement of the stator housing.

[0005] In some embodiments, the inner support assembly pressing head includes a first pressing head and a mating pressing head, the mating pressing head being located at the bottom end of the first pressing head and protruding downwards; both the first pressing head and the mating pressing head are cylindrical in shape, and the diameter of the first pressing head is larger than the diameter of the mating pressing head.

[0006] In some embodiments, the inner support assembly includes an outer ring and an inner support block that fits within the outer ring; the mating pressure head is adapted to press into the center of the inner support block, and the pressing area of ​​the bottom surface of the first pressure head covers the force-bearing edge of the inner support block.

[0007] In some embodiments, the bottom end of the mating pressure head is provided with a tapered guide surface, the outer diameter of which gradually decreases from top to bottom.

[0008] In some embodiments, the pressing area of ​​the bottom surface of the stator housing pressure head covers the outer peripheral force-bearing edge of the top of the stator housing.

[0009] In some embodiments, the bottom surface of the stator housing pressure head is provided with a ring-shaped array of pressure sensors, which corresponds to the outer peripheral force-bearing edge of the top of the stator housing.

[0010] In some embodiments, the output end of the linear conveying mechanism is provided with a supporting base plate, and the top surface of the supporting base plate is provided with an elastic buffer mechanism. The top of the elastic buffer mechanism is fixedly connected to the bottom of the fixture through the supporting top plate.

[0011] In some embodiments, the elastic buffer mechanism is a graded buffer adjustment mechanism; the graded buffer adjustment mechanism includes at least two sets of elastic buffer elements with different elastic coefficients, and the at least two sets of elastic buffer elements are subjected to force sequentially as the fixture moves downward in order of increasing elastic coefficient.

[0012] In some embodiments, at least two sets of the elastic buffer elements are arranged coaxially from top to bottom in the vertical direction in order of increasing elastic coefficient.

[0013] In some embodiments, at least two sets of the elastic buffer elements are arranged coaxially from the inside to the outside in the radial direction in order of increasing elastic coefficient.

[0014] The beneficial effects of this invention are as follows: Unlike the prior art, in the device for separating the stator housing and the inner support assembly of this invention, the platform of the fixture is used to support the inner support assembly fitted with the stator housing, and the linear conveying mechanism is used to realize the stable conveying and precise positioning of the fixture between the lower pressure head of the inner support assembly and the lower pressure head of the stator housing. In turn, the lifting drive mechanism drives the lifting platform to move, so that the lower pressure head of the inner support assembly and the lower pressure head of the stator housing can apply force to the inner support assembly and the stator housing on the fixture in sequence, thereby realizing the reliable separation of the inner support assembly and the stator housing. The overall structure is reasonably laid out, and the action is coordinated and stable. There is no need for manual assistance in alignment or knocking disassembly. Not only is the operation simpler and faster, greatly improving the separation efficiency, but it can also avoid damage to the inner support assembly, the stator housing and the magnet during the disassembly process, effectively ensuring the integrity of the product and the assembly quality.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] This invention provides a device for separating the stator housing from the internal support assembly, such as... Figures 1 to 4 As shown, the device for separating the stator housing and the inner support assembly includes a frame 1, on which a linear conveying mechanism 2 and a lifting drive mechanism 3 are provided. The lifting drive mechanism 3 is located above the linear conveying mechanism 2. The output end of the lifting drive mechanism 3 is provided with a lifting platform 4. The bottom surface of the lifting platform 4 is respectively provided with an inner support assembly pressing head 5 and a stator housing pressing head 6. The inner support assembly pressing head 5 and the stator housing pressing head 6 are distributed at intervals along the conveying direction of the linear conveying mechanism 2. The output end of the linear conveying mechanism 2 is provided with a fixture 7 to drive the fixture 7 to move back and forth between the inner support assembly pressing head 5 and the stator housing pressing head 6. The top of the fixture 7 is provided with a platform to support the inner support assembly 8. The outer peripheral sidewall of the fixture 7 is provided with a recess to avoid the downward movement of the stator housing.

[0022] Frame 1 serves as the mounting base for the entire device; its specific structure can be found in the appendix. Figure 1 The fixture 7 is typically constructed from high-strength steel to ensure structural stability during operation. The lifting drive mechanism 3, for example, uses a hydraulic cylinder, with its output end bolted to the lifting platform 4. This allows for precise control of the lifting height and speed of the lifting platform 4, meeting the pressing accuracy requirements during the separation process. The inner support component pressing head 5 and the stator housing pressing head 6 are bolted to the bottom surface of the lifting platform 4. The distance between the inner support component pressing head 5 and the stator housing pressing head 6 matches the length of the fixture 7, ensuring that the fixture 7 can move precisely under both and guarantee the pressing action. The linear conveying mechanism 2, for example, uses a linear guide module, with the fixture 7 fixedly mounted at its output end. This allows the fixture 7 to move back and forth between the inner support component pressing head 5 and the stator housing pressing head 6, achieving precise positioning of the fixture 7. The top of the fixture 7 has an integrally formed platform for supporting the inner support component 8. By creating a recess in the outer peripheral sidewall of the fixture 7 to prevent the stator housing from moving downward, it is ensured that the stator housing can move downward smoothly a suitable distance under pressure without interfering with the outer peripheral sidewall of the fixture 7, thereby ensuring that the stator housing can be separated from the outer ring 81 of the inner support assembly 8.

[0023] Specifically, in this embodiment, the inner support assembly's lower pressure head 5 includes a first pressure head 51 and a mating pressure head 52. The mating pressure head 52 is integrally formed on the bottom end of the first pressure head 51 and protrudes downward. Both the first pressure head 51 and the mating pressure head 52 are cylindrical in shape, for example, cylindrical; and the diameter of the first pressure head 51 is larger than the diameter of the mating pressure head 52. Wherein, as... Figure 5 As shown, the inner support assembly 8 includes an outer ring 81 and an inner support block 82 that fits within the outer ring 81. The inner wall of the outer ring 81 and the outer wall of the inner support block 82 are designed with a tapered self-locking angle. Pressing down on the inner support block 82 can expand the outer ring 81, thereby supporting the magnet through the outer ring 81. Conversely, when separating the inner support assembly 8 from the stator housing, the inner support assembly 8 with the stator housing fitted on it is placed upside down on the platform of the fixture 7. Then, through the downward pressing action of the first pressure head 51 and the cooperating pressure head 52, the inner support block 82 can be moved downward to gradually release the resistance to the outer ring 81. The outer ring 81 will gradually retract inward and loosen between itself and the stator housing.

[0024] The inner support block 82 is fitted with a pressure head 52 and pressed into its center. The center of the inner support block 82 has a corresponding through hole for the pressure head 52 to be fitted into. The through hole passes through the upper and lower end faces of the inner support block 82. The pressing area of ​​the bottom surface of the first pressure head 51 covers the force-bearing edge of the inner support block 82, thereby ensuring that the inner support block 82 of the inner support assembly 8 can be accurately pressed when pressed down, and avoiding damage to the inner support assembly 8 due to uneven force.

[0025] Furthermore, the bottom end of the pressure head 52 is provided with a tapered guide surface. The outer diameter of the tapered guide surface gradually decreases from top to bottom. This tapered guide surface can accurately guide the inner support component 8 during the pressing process, making it easy for the pressure head 52 to quickly align with the through hole extending into the center of the inner support block 82, while avoiding deviation during pressing and improving pressing accuracy.

[0026] Specifically, in this embodiment, the pressing area of ​​the bottom surface of the stator housing pressing head 6 covers the outer periphery of the top of the stator housing, ensuring uniform force on the stator housing during pressing and preventing excessive local force that could cause deformation. The downward pressure of the stator housing pressing head 6 completely separates the stator housing from the outer ring 81 of the inner support assembly 8. A clearance groove 601 is also provided at the center of the bottom surface of the stator housing pressing head 6 to prevent interference with the inner support assembly 8 during pressing.

[0027] Furthermore, a ring-shaped array of pressure sensors 9 is embedded on the bottom surface of the stator housing pressing head 6. The pressure sensor array 9 corresponds to the outer peripheral force-bearing edge of the top of the stator housing. The pressure sensor array 9 is electrically connected to an external controller (not shown) via wires, enabling real-time monitoring of pressure changes during the pressing process and transmitting the pressure signal to the external controller (not shown). When the pressure exceeds a preset threshold, the external controller (not shown) controls the lifting drive mechanism 3 to stop pressing, preventing damage to related components. The preset threshold can be designed and selected according to actual application needs and is not specifically limited here.

[0028] Specifically, in this embodiment, a support base plate 10 is fixedly installed at the output end of the linear conveying mechanism 2, and an elastic buffer mechanism 11 is fixedly installed on the top surface of the support base plate 10. The top of the elastic buffer mechanism 11 is fixedly connected to the bottom of the fixture 7 through a support top plate 12. The elastic buffer mechanism 11 is a graded buffer adjustment mechanism; the graded buffer adjustment mechanism includes at least two sets of elastic buffer elements with different elastic coefficients. The at least two sets of elastic buffer elements are sequentially stressed as the fixture 7 moves downwards, in order of increasing elastic coefficient.

[0029] Accordingly, at least two sets of elastic buffer elements are arranged coaxially from top to bottom in the vertical direction, in order of increasing elastic coefficient. In other embodiments, at least two sets of elastic buffer elements are arranged coaxially from inside to outside in the radial direction, in order of increasing elastic coefficient.

[0030] In this system, at least two sets of elastic buffer elements, whether arranged coaxially from top to bottom or from inside to outside, operate on the same principle: when the fixture 7 moves downward under downward pressure, the elastic buffer element with the smaller elastic coefficient is compressed first, providing a smaller buffering force to cushion the initial impact force. As the fixture 7 continues to move downward, after the elastic buffer element with the smaller elastic coefficient is compressed to its limit, the next elastic buffer element with the larger elastic coefficient begins to be compressed, providing a larger buffering force to support the fixture 7 and prevent damage caused by excessive downward pressure. This process continues, thereby achieving graded buffering adjustment to adapt to the separation requirements of products of different specifications.

[0031] Therefore, based on the aforementioned principle of graded buffering adjustment, the structural layout of at least two sets of elastic buffering elements should be designed to achieve the purpose of graded buffering adjustment, without making specific limitations here.

[0032] It should be noted that since the application of elastic buffer elements is relatively existing, in practical applications, any suitable structure from the existing technology can be used, as long as it can achieve the purpose of elastic buffering, and no specific limitation is made here.

[0033] Specifically, in this embodiment, the frame 1 is also equipped with two relatively distributed positioning sensors 13. The detection lines of the two positioning sensors 13 coincide and are both perpendicular to the conveying direction of the linear conveyor mechanism 2. For example, both positioning sensors 13 are set close to the loading position of the linear conveyor mechanism 2 to detect whether the loading is in place, so as to ensure the stable operation of subsequent work. The relatively distributed arrangement of the two positioning sensors 13 can also ensure detection accuracy and effectively reduce detection errors.

[0034] The positioning sensor 13 may be a laser or infrared sensor, for example.

[0035] It is understood that although the inner wall of the stator housing in the attached figure does not show several magnets, in this embodiment, the stator housing that needs to be separated from the inner support assembly 8 is specifically a stator housing with several magnets fixedly bonded to its inner wall.

[0036] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
