Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0025] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0027] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0028] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0029] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0030] In this embodiment of the application, for the sake of convenience in describing direction, Figures 1 to 8 Each direction is indicated, wherein the first direction is the height direction of the housing 1, the second direction is the length direction of the housing 1, and the third direction is the width direction of the housing 1. The first, second, and third directions are perpendicular to each other. It should be noted that the direction markings are only used to describe this application and are not intended to limit the scope of this application.

[0031] As electronic devices become thinner, lighter, and more precise, the requirements for the surface quality of the electronic device housing 1 are increasing. Finishing, as the final process in the manufacturing of the housing 1, directly affects its appearance and texture. However, related technologies often produce tool marks on the surface of the housing 1 during the finishing process, severely impacting product yield.

[0032] To address the aforementioned problems, this application provides a fixture, as shown in the embodiments below. Figure 1 , Figure 2 and Figure 3 The fixture can be used to fix a housing 1. The inner surface of the housing 1 can include a first surface 11, which can have a first region 111 and a second region 112 surrounding the first region 111. Both the first region 111 and the second region 112 can be provided with functional structures (not shown in the figure), and the area of ​​the functional structure on the second region 112 can be larger than the area of ​​the functional structure on the first region 111. The outer surface of the housing 1 can include a second surface 12, which can be disposed opposite to the first surface 11 along a first direction. (Refer to...) Figure 1 The fixture may include a base 2, a first positioning member 31, a second positioning member 32, and a positioning structure. The base 2 may have a bearing surface 21. The first positioning member 31 may be disposed on the bearing surface 21 and may be used to push the first region 111 along a first direction. The second positioning member 32 may be disposed around the first positioning member 31 on the bearing surface 21 and may be movably disposed relative to the bearing surface 21 along the first direction to push the second region 112 along the first direction. The positioning structure may include a fixing member and a third positioning member 33. The fixing member may be disposed on the bearing surface 21 and may be used to fix the third positioning member 33 so that the third positioning member 33 pushes the second surface 12 along the first direction.

[0033] It should be noted that the casing 1 mentioned in this application embodiment can be a laptop casing, a mobile phone casing, a game console casing, etc., and this application embodiment does not impose any limitations on this. In one possible implementation provided in this application embodiment, the electronic device is a laptop computer.

[0034] In this embodiment, the inner surface of the housing 1 refers to the side of the housing 1 facing the inside of the electronic device, that is, the surface that is in contact with or close to the internal components of the electronic device (such as circuit boards, batteries, chips, etc.). The outer surface of the housing 1 refers to the side of the housing 1 facing the outside of the device, that is, the surface that is directly exposed to the external environment and is in contact with or visible to the user.

[0035] In this embodiment, the first surface 11 can have several possibilities. For example, the first surface 11 can be the bottom surface of the inner surface of the housing 1. The bottom surface is usually the largest part of the inner surface of the housing 1, and it directly undertakes the function of installing and supporting the internal components of the electronic device. Alternatively, the first surface 11 can also be a side surface of the inner surface of the housing 1, and the side surface is usually arranged around the perimeter of the housing 1.

[0036] In this embodiment, the first surface 11 may have a first region 111 and a second region 112. Both the first region 111 and the second region 112 may be provided with functional structures. Here, a functional structure refers to a structure designed to achieve a specific function. For example, a functional structure may include a fixing structure, such as a stud, a snap fastener, or a fixing post; a functional structure may include a reinforcing structure, such as a reinforcing rib, a supporting post, or a rib plate; a functional structure may also include an assembly guiding structure, such as a guide post, a guide groove, or a positioning hole; and a functional structure may also include a wiring structure, such as a wire groove or a wire clip. This embodiment does not limit the scope of the application.

[0037] In this embodiment, the distribution of functional structures on the first surface 11 is affected by various factors, mainly including: 1. As the edge region of the first surface 11, the second region 112 experiences more concentrated forces (such as clamping forces during assembly and external impact forces during use). Therefore, the second region 112 will have more reinforcing ribs, support columns, and other structures to improve strength compared to the first region 111. 2. As the edge region of the first surface 11, the second region 112 facilitates the assembly and disassembly of its fixing structures. Therefore, the second region 112 will have more fixing structures, such as studs, clips, and fixing columns, compared to the first region 111. 3. As the central region of the first surface 11, designing too many functional structures in the first region 111 will increase the weight of the housing 1, affecting the portability of the device. In summary, the area of ​​functional structures on the second region 112 will be larger than the area of ​​functional structures on the first region 111. The uneven arrangement of functional structures on the first surface 11 will cause uneven contact between the fixture and the first surface 11, resulting in uneven distribution of the fixing force of the fixture on the housing 1, which in turn leads to unstable fixing of the housing 1 on the fixture, thus affecting the processing quality of the housing 1.

[0038] In this embodiment, the base 2 can refer to the basic platform or frame in the fixture used to connect other functional modules (such as the first positioning element 31, the second positioning element 32, and the positioning structure, etc.), and the bearing surface 21 on the base 2 can be used to support other functional modules to ensure that each functional module can maintain a stable position and posture during the processing.

[0039] In this embodiment, the first positioning member 31, the second positioning member 32, and the third positioning member 33 can all be used to push the housing 1, and therefore, their structural forms are possible in various ways. For example, the first positioning member 31, the second positioning member 32, and the third positioning member 33 can be a block structure, a rod structure, or a plate structure, and this embodiment does not limit them in this way.

[0040] In the technical solution provided in this application embodiment, the fixture may include a base 2, a first positioning member 31, a second positioning member 32, and a positioning structure. The first positioning member 31 is disposed on the bearing surface 21, and the second positioning member 32 is disposed around the first positioning member 31. The second positioning member 32 may also be movably disposed relative to the bearing surface 21 along a first direction. The positioning structure may include a fixing member and a third positioning member 33. The fixing member may be disposed on the bearing surface 21, and the third positioning member 33 may be fixed relative to the bearing surface 21 by the fixing member. When using the jig to fix the housing 1, firstly, the first surface 11 of the housing 1 can be placed facing the bearing surface 21, with the first area 111 on the first surface 11 aligned with the first positioning member 31 on the bearing surface 21 along the first direction, and the second area 112 on the first surface 11 aligned with the second positioning member 32 on the bearing surface 21 along the first direction. Then, the third positioning member 33 is placed on the side of the housing 1 facing away from the bearing surface 21, and fixed with a fixing member, so that the third positioning member 33 pushes against the second surface 12 along the first direction. Finally, the position of the second positioning member 32 is adjusted along the first direction so that the second positioning member 32 is in reliable contact with the second area 112. Thus, the jig completes the fixing of the housing 1 in the first direction. As can be seen from the above fixing process, the jig uses the first positioning member 31, the second positioning member 32, and the third positioning member 33 to press against the opposite sides of the housing 1, forming a symmetrical clamping force. In this way, on the one hand, the housing 1 can be kept balanced in the first direction, reducing the shaking or displacement of the housing 1 in the first direction and improving the stability of the housing 1 during processing; on the other hand, the clamping method between the two sides can make the clamping force evenly distributed on both sides of the housing 1, reducing the probability of damage or deformation of the housing 1 due to uneven force, especially for thin-walled or easily deformable housing 1, thereby reducing rework and scrap rates. In addition, the first positioning member 31 and the second positioning member 32 are respectively used to push the first region 111 and the second region 112 of the first surface 11. Since the first region 111 and the second region 112 have different structures, the first positioning member 31 and the second positioning member 32 can respectively push the corresponding regions, which can increase the contact area between the housing 1 and the fixture, thereby improving the stability of fixing the housing 1. The second positioning member 32 is movably arranged relative to the bearing surface 21 in the first direction. In this way, by changing the position of the second positioning member 32, the pushing force of the second positioning member 32 on the second region 112 can be adjusted, which is conducive to the even distribution of the pushing force and reduces the probability of damage to the housing 1 due to local stress concentration.

[0041] In this embodiment, the fixing member can serve to fix the third positioning member 33. Therefore, the structural design of the fixing member has various possibilities. For example, the fixing member can be a bolt, and the third positioning member has a threaded hole for connection with the bolt. In one possible embodiment of this application, the housing 1 is made of a non-magnetic material, the fixing member is a magnetic member, and the third positioning member 33 is provided with a magnetic element. The magnetic member attracts the third positioning member 33 along the first direction through the magnetic element. In this way, the fixing member can quickly attract the third positioning member 33 through magnetic force, so that the third positioning member 33 can press the housing 1 tightly along the first direction, reducing the disassembly and assembly time of the third positioning member 33 and improving production efficiency. In addition, the magnetic member has a simple structure, does not require a complex mechanical structure, and reduces the design and manufacturing cost of the fixture.

[0042] In this embodiment of the application, when the material of the shell 1 is a non-magnetic material, the material of the shell 1 can be aluminum alloy, magnesium alloy, or titanium alloy. This embodiment of the application does not limit this.

[0043] In this embodiment, the location of the fastener can be varied. For example, the fastener can be directly mounted on the bearing surface 21; or, the fastener can be mounted on the second positioning member 32. This embodiment does not limit the choice of fastener. Furthermore, the number of fasteners can be varied. For example, there can be one or more fasteners. This embodiment also does not limit the number of fasteners.

[0044] In this embodiment, multiple first positioning members 31 are provided on the bearing surface 21, and the number of magnetic suction members is the same as the number of first positioning members 31, so that each magnetic suction member corresponds to one of the first positioning members 31, and the magnetic suction member is disposed on the corresponding first positioning member 31. Here, providing multiple first positioning members 31 on the bearing surface 21 can increase the contact area between the first positioning member 31 and the first region 111, thereby improving the stability of the support for the housing 1. The number of magnetic suction members is the same as the number of first positioning members 31, so that each magnetic suction member corresponds to one of the first positioning members 31, and the magnetic suction member is disposed on the corresponding first positioning member 31. In this way, the number of parts of the fixture can be reduced, and the overall structure of the fixture can be simplified.

[0045] Here, it needs to be explained that when the magnetic attractor is set in the first positioning member 31, the magnetic attractor and the first positioning member 31 can form an integral structure. For example, the magnetic attractor and the first positioning member 31 together form an electromagnet. While the electromagnet pushes the first region 111 along the first direction, it can also fix the third positioning member 33 by magnetic attraction. Alternatively, the magnetic attractor and the first positioning member 31 can also be separate structures. For example, along the first direction, the magnetic attractor and the first positioning member 31 can be stacked.

[0046] In this embodiment, the arrangement of the first positioning element 31 on the bearing surface 21 can be varied. For example, multiple first positioning elements 31 can be arranged in an array on the bearing surface 21; or, multiple first positioning elements 31 can be arranged linearly on the bearing surface 21; or, multiple first positioning elements 31 can be arranged irregularly on the bearing surface 21. This embodiment does not limit the arrangement of these elements. It should be noted that when designing the arrangement of the first positioning elements 31 on the bearing surface 21, the first positioning elements 31 can be made to avoid the functional structures in the first region 111 to increase the contact area between the first positioning elements 31 and the first region 111.

[0047] Reference Figure 6 , Figure 7 and Figure 8 In this embodiment of the application, the third positioning member 33 may include a cover plate 331, which may have a recess 3311. The recess 3311 may be positioned toward the second surface 12 so that when the cover plate 331 pushes against the second surface 12 in the first direction, a closed cavity is formed between the cover plate 331 and the housing 1. The fixture may also include an air guide member 46, which may be disposed on the base 2. The air guide member 46 may have an air guide hole 461. One end of the air guide hole 461 may be used to communicate with the closed cavity, and the other end of the air guide hole 461 may be used to communicate with a suction device so that the suction device can extract the gas from the closed cavity. In this way, when the fixing member is fixed to the third positioning member 33, a closed cavity can be formed between the recess 3311 on the cover plate 331 and the second surface 12 on the housing 1. The air extraction device can extract the gas in the closed cavity through the air guide hole 461 on the air guide member 46, so that a negative pressure is generated in the closed cavity, thereby generating a pushing force on the second surface 12 in the direction close to the bearing surface 21, which further improves the reliability of the housing 1 in the first direction.

[0048] In this embodiment, the second positioning member 32 can be positioned on the bearing surface 21 in various ways. For example, a first guide rail extending in a first direction can be provided on the bearing surface 21, and the second positioning member 32 can be movably mounted on the first guide rail in the first direction. The position of the second positioning member 32 on the first guide rail can be manually adjusted. (Refer to...) Figure 1 and Figure 5In one possible embodiment of this application, the fixture further includes a first driving member 41, which is disposed on the side of the base 2 facing away from the bearing surface 21. The base 2 has a through hole, and the first driving member 41 is connected to the second positioning member 32 through the through hole to drive the second positioning member 32 to move in a first direction. Here, the fixture also includes the first driving member 41, which can precisely control the movement speed and force of the second positioning member 32, reducing the probability of damage to the surface of the housing 1 due to improper operation. The first driving member 41 is disposed on the side of the base 2 facing away from the bearing surface 21, and the base 2 has a through hole, through which the first driving member 41 is connected to the second positioning member 32. In this way, on the one hand, the space occupied by the first driving member 41 on the front of the fixture can be reduced, making the layout of the fixture more compact; on the other hand, the first driving member 41 is disposed on the back side of the bearing surface 21, which can prevent chips, coolant or dust generated during processing from directly contacting the first driving member 41, reducing the wear and failure of the first driving member 41, thereby extending the service life of the first driving member 41.

[0049] Reference Figure 1 In this embodiment, multiple second positioning members 32 can be arranged at intervals around the first positioning member 31. The number of second positioning members 32 can be the same as the number of first driving members 41, so that they correspond one-to-one with the first driving members 41. The second positioning members 32 can be connected to the corresponding first driving members 41 in a transmission manner. Here, providing multiple second positioning members 32 can increase the contact area between the second positioning members 32 and the second region 112, thereby improving the stability of the support for the housing 1. The one-to-one correspondence between the second positioning members 32 and the first driving members 41 allows for precise adjustment of the position and pushing force of each second positioning member 32, ensuring the fit between the housing 1 and the fixture.

[0050] In this embodiment, the number of second positioning elements 32 can be varied. For example, only one second positioning element 32 may be provided, which is a ring structure arranged around the first positioning element 31; or, ten second positioning elements 32 may be provided, arranged at intervals around the first positioning element 31. This embodiment does not limit this. It should be noted that when designing the specific position of the second positioning element 32 on the bearing surface 21, the second positioning element 32 can be made to avoid the functional structure at the second region 112, so as to increase the contact area between the second positioning element 32 and the second region 112.

[0051] Reference Figure 4In this embodiment, the functional structure of the first region 111 includes at least a first reinforcing structure 1111, and the functional structure of the second region 112 includes at least a second reinforcing structure 1121. The area of ​​the first reinforcing structure 1111 is larger than the area of ​​the second reinforcing structure 1121. At least a portion of the first positioning member 31 is used to push the first reinforcing structure 1111 along a first direction, and at least a portion of the second positioning member 32 is used to push the second reinforcing structure 1121 along the first direction. When the shell 1 is processed, the stress concentration phenomenon in the first region 111 of the shell 1 is more obvious than that in the second region 112. The area of ​​the first reinforcing structure 1111 in the first region 111 is larger than the area of ​​the second reinforcing structure 1121 in the second region 112, which can effectively disperse stress and enhance the overall rigidity and deformation resistance of the shell 1. At least a portion of the first positioning member 31 is used to push the first reinforcing structure 1111 along the first direction, and at least a portion of the second positioning member 32 is used to push the second reinforcing structure 1121 along the first direction. In this way, on the one hand, the pushing force of the first positioning member 31 on the housing 1 can be directly transmitted to the first reinforcing structure 1111, and the pushing force of the second positioning member 32 on the housing 1 can be directly transmitted to the second reinforcing structure 1121. The first reinforcing structure 1111 and the second reinforcing structure 1121 can evenly distribute the pushing force and reduce local stress concentration. On the other hand, the first reinforcing structure 1111 and the second reinforcing structure 1121 can be evenly distributed on the inner wall surface of the housing, which facilitates providing stable support points for the first positioning member 31 and the second positioning member 32, and helps to improve the reliability of the housing 1 in the first direction.

[0052] In this embodiment of the application, the structural design of the first reinforcing structure 1111 and the second reinforcing structure 1121 can be a variety of possibilities. For example, the first reinforcing structure 1111 and the second reinforcing structure 1121 can be reinforcing ribs or bosses. This embodiment of the application does not limit this.

[0053] In this embodiment, when the first positioning member 31 pushes against the first region 111 along the first direction, the first positioning member 31 may partially push against the first reinforcing structure 1111 along the first direction, or it may push against the first reinforcing structure 1111 entirely along the first direction. This embodiment does not impose any limitation on this. When the second positioning member 32 pushes against the second region 112 along the second direction, the second positioning member 32 may partially push against the second reinforcing structure 1121 along the first direction, or it may push against the second reinforcing structure 1121 entirely along the first direction. This embodiment does not impose any limitation on this.

[0054] Reference Figure 1 , Figure 2 and Figure 7In this embodiment, the inner surface of the housing 1 may further include a third surface 13 and a fourth surface 14 disposed opposite to each other along a second direction. The fixture also includes a fourth positioning member 34 and a fifth positioning member 35. The fourth positioning member 34 and the fifth positioning member 35 are movably disposed on the bearing surface 21 along the second direction. The fourth positioning member 34 is used to push the third surface 13 along the second direction, and the fifth positioning member 35 is used to push the fourth surface 14 along the second direction. The second direction is perpendicular to the first direction. After the fixture has fixed the housing 1 in the first direction, the positions of the fourth positioning member 34 and the fifth positioning member 35 can be adjusted along the second direction, so that the fourth positioning member 34 pushes the third surface 13 along the second direction, and the fifth positioning member 35 pushes the fourth surface 14 along the second direction, thereby completing the fixation of the housing 1 in the second direction. In this way, the housing 1 can be prevented from moving horizontally or rotating during processing, further enhancing the stability of the housing 1.

[0055] In this embodiment, the fourth positioning member 34 and the fifth positioning member 35 can be arranged on the bearing surface 21 in various ways. For example, a second guide rail extending along the second direction can be provided on the bearing surface 21, and the fourth positioning member 34 and the fifth positioning member 35 can be movably mounted on the second guide rail along the second direction. The positions of the fourth positioning member 34 and the fifth positioning member 35 on the second guide rail can be manually adjusted. (Refer to...) Figure 1 and Figure 4 In one possible embodiment of this application, the fixture further includes a second driving member 42 and a third driving member 43. The second driving member 42 is driveably connected to the fourth positioning member 34, and the third driving member 43 is driveably connected to the fifth positioning member 35, so as to drive the fourth positioning member 34 and the fifth positioning member 35 to move closer or further apart along a second direction, respectively. The second driving member 42 is positioned along the second direction on the side of the fourth positioning member 34 facing away from the first positioning member 31, and the third driving member 43 is positioned along the second direction on the side of the fifth positioning member 35 facing away from the first positioning member 31. Here, the fixture further includes the second driving member 42 and the third driving member 43. The second driving member 42 and the third driving member 43 can precisely control the movement speed and force of the fourth positioning member 34 and the fifth positioning member 35, reducing the probability of surface damage to the housing 1 due to improper operation. The second driving member 42 is positioned along the second direction on the side of the fourth positioning member 34 facing away from the first positioning member 31, and the third driving member 43 is positioned along the second direction on the side of the fifth positioning member 35 facing away from the first positioning member 31. In this way, the second driving component 42 and the third driving component 43 can be prevented from encroaching on the arrangement space of the first positioning component 31, so that more first positioning components 31 can be arranged on the bearing surface 21, thereby improving the support effect on the housing 1.

[0056] Reference Figure 1 , Figure 2 and Figure 8In this embodiment, the inner surface of the housing 1 further includes a fifth surface 15 and a sixth surface 16 disposed opposite each other along a third direction. The fixture also includes a sixth positioning member 36 and a seventh positioning member 37. The sixth positioning member 36 and the seventh positioning member 37 are movably disposed on the bearing surface 21 along a third direction. The sixth positioning member 36 is used to push the fifth surface 15 along the third direction, and the seventh positioning member 37 is used to push the sixth surface 16 along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. After the fixture has fixed the housing 1 in the first and second directions, the positions of the sixth positioning member 36 and the seventh positioning member 37 can be adjusted along the third direction, so that the sixth positioning member 36 pushes the fifth surface 15 along the third direction, and the seventh positioning member 37 pushes the sixth surface 16 along the second direction, thereby fixing the housing 1 in the third direction. In this way, the position and orientation of the housing 1 in space can be completely fixed, which can effectively prevent the housing 1 from moving or rotating in any direction during processing, enhance the overall stability, and meet the processing needs of the housing 1 in multiple directions.

[0057] In this embodiment, the arrangement of the sixth positioning member 36 and the seventh positioning member 37 on the bearing surface 21 can be varied. For example, a third guide rail extending along a third direction can be provided on the bearing surface 21, and the sixth positioning member 36 and the seventh positioning member 37 can be movably mounted on the third guide rail along the third direction. The positions of the sixth positioning member 36 and the seventh positioning member 37 on the third guide rail can be manually adjusted. (Refer to...) Figure 1 and Figure 5 In one possible embodiment of this application, the fixture further includes a fourth driving member 44 and a fifth driving member 45. The fourth driving member 44 is driveably connected to the sixth positioning member 36, and the fifth driving member 45 is driveably connected to the seventh positioning member 37, so as to drive the sixth positioning member 36 and the seventh positioning member 37 to move closer or further apart along a third direction. The fourth driving member 44 is positioned along a third direction on the side of the sixth positioning member 36 facing away from the first positioning member 31, and the fifth driving member 45 is positioned along a third direction on the side of the seventh positioning member 37 facing away from the first positioning member 31. Here, the fixture further includes the fourth driving member 44 and the fifth driving member 45. The fourth driving member 44 and the fifth driving member 45 can precisely control the movement speed and force of the sixth positioning member 36 and the seventh positioning member 37, reducing the probability of surface damage to the housing 1 due to improper operation. The fourth driving member 44 is positioned along a third direction on the side of the sixth positioning member 36 facing away from the first positioning member 31, and the fifth driving member 45 is positioned along a third direction on the side of the seventh positioning member 37 facing away from the first positioning member 31. In this way, the fourth driving component 44 and the fifth driving component 45 can be prevented from encroaching on the arrangement space of the first positioning component 31, so that more first positioning components 31 can be arranged on the bearing surface 21, thereby improving the support effect on the housing 1.

[0058] In this embodiment, the positional relationship between the fourth positioning element 34, the fifth positioning element 35, the sixth positioning element 36, and the seventh positioning element 37 and the second positioning element 32 can be varied. For example, the fourth positioning element 34, the fifth positioning element 35, the sixth positioning element 36, and the seventh positioning element 37 can enclose a target space in the circumferential direction, and both the first positioning element 31 and the second positioning element 32 are disposed within the target space. (Refer to...) Figure 1 In one possible embodiment of this application, the fourth positioning member 34, the fifth positioning member 35, the sixth positioning member 36, and the seventh positioning member 37 can enclose a target space in the circumferential direction, and each of the fourth positioning member 34, the fifth positioning member 35, the sixth positioning member 36, and the seventh positioning member 37 can be provided with a clearance portion 38. The first positioning member 31 can be disposed within the target space, and the second positioning member 32 can be disposed within the clearance portion 38. It should be noted that the size of the clearance portion 38 must be larger than the size of the second positioning member 32 to avoid interference between the fourth positioning member 34, the fifth positioning member 35, the sixth positioning member 36, and the seventh positioning member 37 during operation.

[0059] This application embodiment also provides a method for processing the housing 1. This method is applied to a fixture provided in this application embodiment.
