Description

Technical Field

[0001] This disclosure relates to the field of transmission technology, and in particular to disassembly and assembly tooling. Background Technology

[0002] In the automotive manufacturing and repair field, the transmission tower assembly, as a key component of the vehicle's powertrain, is crucial for ensuring vehicle performance through its installation and removal. However, the installation and removal process of the transmission tower assembly in related technologies faces a series of challenges. These problems not only affect work efficiency but may also lead to component damage or reduced assembly precision, thereby impacting overall vehicle performance.

[0003] The transmission tower assembly consists of multiple precision components, each with strict relative positional requirements. However, in actual assembly, without specialized positioning and guiding devices, relying solely on manual visual inspection or experience for positioning makes it difficult to ensure precise fit between components. In such cases, even minor positional deviations can lead to uneven stress distribution, affecting the overall performance and lifespan of the transmission. Disassembly and assembly of the transmission tower assembly in related technologies typically requires the collaborative work of multiple technicians, a process that is time-consuming and labor-intensive. Different brands or models of transmissions vary in size, specifications, and interface types, making it difficult for existing tooling to achieve good compatibility. This necessitates the preparation of a large amount of specialized equipment during production or maintenance, increasing costs and management complexity. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this disclosure is to provide solutions to the problems in the related art.

[0031] The transmission tower assembly is one of the key structural components in an automotive transmission system. It is typically located above the transmission housing and serves as a bridge connecting the control mechanism to the internal gear transmission system. Therefore, the assembly quality of the transmission tower assembly directly affects the vehicle's shifting performance, driving experience, and the transmission's lifespan.

[0032] Despite the crucial role of the transmission tower assembly in a vehicle's drivetrain, the following technical challenges and shortcomings remain during actual installation: The installation methods rely on manual visual inspection and experience for positioning, leading to inaccurate fits between parts and potential misalignment or displacement, affecting overall assembly precision. Without specialized tooling, installers must frequently adjust angles and perform repeated trial installations, which is not only time-consuming and labor-intensive but also prone to errors due to fatigue, further impacting installation quality. Disassembly requires loosening or separating multiple connection points; without effective fixing and guiding devices, friction and collisions between parts can easily occur, damaging precision components. Furthermore, transmission tower assemblies vary across different vehicle models in terms of structural dimensions and interface types, while existing installation methods and tools are often only applicable to specific models, lacking versatility. This necessitates companies preparing multiple specialized equipment, increasing manufacturing costs and management complexity.

[0033] To address the aforementioned problems, one embodiment of this disclosure provides a disassembly and assembly fixture for installing and disassembling an assembly. Figure 1 In this embodiment, the assembly / disassembly fixture includes a connector 100, an assembly component 200, and a disassembly component 300. The connector 100 has a first connecting end and a second connecting end; the assembly component 200 is located at the first connecting end, and the disassembly component 300 is located at the second connecting end, forming an integrated operating platform. The assembly allows parts to be positioned according to their size before assembly, resulting in more precise fit between parts, easier installation, and eliminating the need for angle adjustments by the installer, thus avoiding repeated disassembly and assembly. The disassembly component 300 provides a positioning platform; after placing the assembly component on the disassembly component 300, the installer can easily disassemble the assembly. Furthermore, the assembly component 200 and / or the disassembly component 300 are detachably connected to the connector 100. Integrating the assembly component 200 and the disassembly component 300 into one unit also facilitates disassembly and assembly, and the detachable assembly component 200 and disassembly component 300 offer greater adaptability. Optionally, the assembly includes a gearbox tower assembly.

[0034] As an example, the connection points between assembly 200 and connector 100 can be correspondingly configured with a male pin and a female socket. The positions of the male pin and female socket are interchangeable, and they are secured by a mechanical locking device (such as a spring clip). When connection is needed, the male pin is inserted into the female socket, and the spring clip is locked by rotating or pressing to complete the connection. When separation is needed, simply press the unlock button; the spring clip will release, and the male pin can be easily removed. The connection between disassembly assembly 300 and connector 100 can be similar, and will not be elaborated further here.

[0035] As an example, the disassembly component 300 and the connector 100 can be threaded together, with corresponding external threads and internal threads. They are connected by rotation. The positions of the internal and external threads can be reversed. To connect, the external thread is screwed into the internal thread until fully tightened. To separate, the disassembly component 300 is rotated counterclockwise to remove it from the connector 100. The connection between the assembly component 200 and the connector 100 can also be achieved in this way, which will not be elaborated further here.

[0036] For example, please refer to Figure 2 In this embodiment, during the example use, the end to be used needs to be aligned with the assembly, and then the assembly is placed on the end to be used. For example, if it is necessary to assemble the assembly, the assembly 200 needs to be placed facing upwards, and then the parts for assembling the assembly are placed in the corresponding positions to begin assembly. Disassembly is similar; therefore, the assembly 200 and the disassembly 300 can also be not fixedly connected to the connector 100, but only need to be inserted into the corresponding ends of the connector 100.

[0037] Optionally, Figure 3 The example is along Figure 2 Please also refer to the sectional view taken along the center section line AA. Figure 1 In one embodiment, the assembly 200 is provided with a first support structure 210, which includes a first positioning interface 2110 for supporting and positioning parts or parts combinations during assembly. Specifically, the first support structure 210 is designed as a groove or boss structure with a specific shape, whose geometry matches the key positioning surfaces of the parts to be assembled. The first positioning interface 2110 not only provides support but also has a guiding function, allowing parts to be smoothly positioned along a predetermined path during installation. For example, during installation, technicians only need to gently place the corresponding parts or parts combinations into the first positioning interface 2110 to automatically complete the initial positioning without additional adjustments. In some embodiments, the first positioning interface 2110 can not only place parts for assembly but also place parts combinations to assemble different combinations together to form an assembly. (Reference) Figure 3 In this embodiment, during the installation process, the parts inside the housing can be placed on the first positioning interface 2110 first, then assembled, and then the housing can be used to cover the assembled parts.

[0038] As an example, in some embodiments, the first support structure 210 includes at least one recessed limiting portion whose contour is adapted to the contact surface of the parts constituting the assembly. For example, when the transmission tower assembly to be assembled includes a mounting base with a regular shape (such as rectangular, circular, or polygonal), the recessed limiting portion is designed as a recessed structure consistent with the shape of the base. The contour of the recessed limiting portion perfectly matches the contact surface of the parts, allowing the parts to naturally embed and automatically align during placement, avoiding positional displacement caused by human operation. The edge structure of the recessed portion limits the parts, preventing lateral movement or rotation during assembly and improving assembly stability.

[0039] As an example, in another embodiment, the first support structure 210 includes multiple countersunk holes of different diameters that are connected to each other. The size and shape of each countersunk hole correspond to the size and shape of the parts or parts combinations that make up the assembly 200. For example, for a transmission tower assembly part with mounting flanges of different diameters, the countersunk hole structure can be set as a multi-stage stepped countersunk hole, with each stage corresponding to a flange size of a certain specification. By setting multiple countersunk holes of different diameters, parts or parts combinations of various sizes can be compatible on the same support structure, achieving "one tool for multiple uses" and improving tooling utilization.

[0040] Optionally, the disassembly component 300 is provided with a second supporting structure, which includes a second positioning interface for supporting and positioning the assembly to be disassembled. The second positioning interface not only provides support but also has a guiding function, allowing the assembly to smoothly detach from its original position along a predetermined path during disassembly. For example, during the disassembly of a transmission tower assembly, technicians only need to gently place the assembly on the second positioning interface to automatically complete the initial positioning without additional adjustments. Workers then disassemble the assembly 200 placed on the second positioning interface layer by layer. In some embodiments, the size of the second positioning interface matches the size of the smallest layer of the assembly to be disassembled; therefore, the parts can be disassembled layer by layer and then directly fall through the disassembly component 300 onto the workbench where the disassembly fixture is placed.

[0041] As an example, the assembly 200 and / or the disassembly 300 form an axial channel to provide support for the assembly by engaging with the shaft extending from the assembly.

[0042] For example, when the gearbox tower assembly to be assembled or disassembled contains a shaft that runs through the structure, the assembly 200 is provided with an axial through-hole matching its diameter. A technician can insert one end of the shaft into the axial channel of the assembly 200 to achieve initial positioning and support of the entire tower assembly. Similarly, the disassembly assembly 300 may also be provided with a similar axial channel to guide and stabilize the shaft's exit path during disassembly.

[0043] As an example, the assembly 200 and / or the disassembly 300 are internally connected with the connector 100 to form an axial channel, so as to form a load-bearing structure for the assembly by cooperating with the shaft extending from the assembly.

[0044] An axial channel can also be formed between the assembly 200 and the connector 100 or the disassembly 300 and the connector 100. In this way, the shaft in the gearbox assembly can pass through the corresponding axial channel to form a positioning function, and the length of the assembly and disassembly body does not need to be very long.

[0045] As an example, an axial channel is formed between the assembly 200, the disassembly 300, and the connector 100. The two ends of the axial channel are located at the assembly 200 and the disassembly 300, respectively, to cooperate with the protruding shafts of the assembly to provide support for the assembly. One end of the assembly 200 has an axial inlet, the connector 100 has a through channel in the middle, and the disassembly 300 has an axial outlet at a corresponding position. The three components combined form a complete axial channel extending from the assembly 200 to the disassembly 300. When the assembly to be disassembled contains a long through shaft, the shaft can pass sequentially through the assembly 200, the connector 100, and finally the disassembly 300, forming an integral axial support structure. Optionally, the length of the axial channel is set to accommodate the longest shaft among the different shafts.

[0046] Optionally, the assembly 200 and the disassembly 300 are respectively provided for different axes of the assembly to pass through in different postures.

[0047] Specifically, in some embodiments, the shafts required for assembly installation and disassembly differ. For example, if a tower assembly has two ends with shafts of different lengths, during installation, the first end of the assembly is placed on the assembly component 200, and the shaft of the first end enters the axial channel from one end of the assembly component 200. During disassembly, the second end of the assembly is placed on one end of the disassembly component 300, and the shaft of the second end enters the axial channel from the opening at one end of the disassembly component 300. Thus, by changing the orientation of the tooling (e.g., when assembling the assembly, the tooling is placed with the assembly component 200 facing upwards to receive the first end; when disassembling the assembly, the tooling is inverted so that the disassembly component 200 faces upwards to receive the second end), the tooling can adapt to the assembly and disassembly requirements under different orientations and shaft engagement states of the assembly, thereby achieving precise bearing and positioning of the assembly throughout the entire assembly and disassembly process.

[0048] Optionally, the two ends of the axial channel form a positioning fit structure with the shaft component, such as a threaded connection structure, a snap-fit ​​connection interface, or a flange docking structure.

[0049] As an example, in some embodiments, one end of the axial channel has an internal thread structure, while the shaft to be assembled or disassembled has a corresponding external thread structure. The two are fixedly connected by thread engagement. The reverse is also true for threaded configurations. When a technician inserts the shaft into the axial channel, rotating the shaft causes its external thread to engage with the internal thread at the channel port, thus achieving a secure connection between the shaft and the tooling.

[0050] As another example, in some embodiments, the port of the axial channel is provided with a resilient snap-fit ​​structure for engaging with a limiting groove or other mating part on the shaft. When the shaft is inserted into the axial channel to a predetermined position, the snap-fit ​​automatically springs into the groove on the shaft, achieving quick locking.

[0051] In another preferred embodiment, the port of the axial channel is provided with a flange mating structure for forming a tight-fitting surface contact positioning with the flange or other planar structure at the end of the shaft. After the shaft is inserted into the axial channel, its end flange is tightly fitted with the flange mating surface of the channel port and can be fixed with bolts, ensuring the stability of the shaft during operation.

[0052] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
