[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] The following is combined with Figures 1 to 2 This invention describes the assembly, support, and adjustment tooling.

[0023] like Figures 1 to 2 As shown in the figure, the assembly support adjustment tooling provided in this embodiment of the utility model includes a fine adjustment module and a coarse adjustment module.

[0024] Specifically, the fine-tuning module includes a fine-tuning device and a support component 1. The support component 1 is disposed on the fine-tuning device and is used to stably and reliably support the components to be assembled.

[0025] Support component 1 can be set as a rectangle, with the length direction of support component 1 being the same as the horizontal direction of support component 1, such as... Figure 1 The direction indicated by x in the middle; the width direction of the support component 1 is the longitudinal direction of the support component 1, such as... Figure 1 The direction indicated by y; the height direction of support component 1 is the vertical direction of support component 1, such as... Figure 1 The direction indicated by z. Any two of the transverse, longitudinal, and vertical directions of support component 1 are perpendicular to each other. When the assembled support adjustment fixture is located on a horizontal ground, the vertical direction of support component 1 is along the vertical direction, and the transverse and longitudinal directions of support component 1 are both along the horizontal direction.

[0026] The fine-tuning device can adjust the position of the support member 1 along any one of the transverse, longitudinal, and vertical directions of the support member 1.

[0027] The fine-tuning device has a higher adjustment accuracy than the coarse-tuning module.

[0028] The fine-tuning device can perform high-precision fine-tuning control on the position of the support component 1 and the components to be assembled located on the support component 1, which is a key guarantee for improving the final assembly accuracy.

[0029] The coarse adjustment module is detachably mounted on the side of the fine adjustment device away from the support component 1. The coarse adjustment module can adjust the position of the fine adjustment module along any one of the transverse, longitudinal, or vertical directions of the support component 1. This design allows the support component 1 to be quickly moved to the vicinity of the target position within a large spatial range, effectively shortening the adjustment time and improving overall work efficiency.

[0030] With this setup, during assembly, the component to be assembled is placed on support component 1. For work scenarios with a large ceiling height, both the coarse adjustment module and the fine adjustment module participate in the operation. First, the coarse adjustment module is used to coarsely adjust the position of the component to be assembled, and then the fine adjustment module is used to finely adjust its position. The fine adjustment module improves the adjustment accuracy of the assembly support adjustment fixture for the position of the component to be assembled, while the coarse adjustment module ensures the adjustment range of the component's position. For work scenarios with a small ceiling height, the fine adjustment module and the coarse adjustment module can be separated. The coarse adjustment module does not participate in the operation, and only the fine adjustment module is used to adjust the position of the component to be assembled. This reduces the fixture height, improves the adaptability of the assembly support adjustment fixture to the ceiling height of the work scenario, avoids the high cost and management inconvenience caused by equipping multiple dedicated fixtures for work scenarios with different ceiling heights, and solves the problems of poor adjustment accuracy of support fixtures for workpiece position and poor adaptability to the ceiling height of work scenarios in related technologies.

[0031] In this embodiment of the present invention, the fine-tuning device includes a lateral adjustment mechanism, a longitudinal adjustment mechanism, and a plurality of first vertical adjustment mechanisms 2.

[0032] A lateral adjustment mechanism is detachably mounted on the coarse adjustment module. The lateral adjustment mechanism is used to adjust the position of the support component 1 laterally. A longitudinal adjustment mechanism is mounted on the output end of the lateral adjustment mechanism. The axis of the lateral adjustment mechanism is perpendicular to the axis of the longitudinal adjustment mechanism. The longitudinal adjustment mechanism is used to adjust the position of the support component 1 longitudinally.

[0033] By combining the synergistic effects of the lateral and longitudinal adjustment mechanisms, comprehensive fine-tuning control of the position of the components to be assembled in the horizontal plane can be achieved.

[0034] Multiple first vertical adjustment mechanisms 2 are disposed at the output end of the longitudinal adjustment mechanism. Each first vertical adjustment mechanism 2 corresponds to a support component 1. That is, multiple support components 1 are also provided. The multiple support components 1 are consistent in the lateral direction and in the longitudinal direction, and the multiple support components 1 together support the component to be assembled. The longitudinal adjustment mechanism can simultaneously fine-tune the position of the multiple first vertical adjustment mechanisms 2, the multiple support components 1, and the component to be assembled along the longitudinal direction of the support components 1.

[0035] The first vertical adjustment mechanism 2 is used to adjust the position of the support component 1 along the vertical direction. Multiple first vertical adjustment mechanisms 2 are spaced apart and relatively independent, and each first vertical adjustment mechanism 2 can operate independently. The vertical positions of any two support components 1 do not affect each other. That is, different support components 1 can be located at the same height to support the component to be assembled whose bottom is horizontal; different support components 1 can also be located at different heights to support the component to be assembled whose bottom is not horizontal. Specifically, the height position of each support component 1 can be adjusted according to the height difference between the bottom of the component to be assembled and the corresponding position points of each support component 1, so that all multiple support components 1 can effectively support the component to be assembled.

[0036] This multi-point, independent design not only enables fine-tuning of the vertical lifting of the components to be assembled, but more importantly, by differentially adjusting the first vertical adjustment mechanism 2 at different positions, it can precisely adjust the pitch and other attitude angles of the components to be assembled to adapt to complex mating surfaces, ensuring optimal fit and assembly precision between the components and the main structure. Simultaneously, the distributed support of multiple support components 1 greatly enhances the stability and reliability of supporting large or irregular components to be assembled.

[0037] In this embodiment, multiple first vertical adjustment mechanisms 2 are distributed at intervals along arcs or broken lines, which can provide more uniform and stable multi-point support and effectively avoid stress concentration or damage to the surface of the components to be assembled due to excessive local force.

[0038] The vertical line of the center of gravity of both the fine-tuning module and the coarse-tuning module is located on the concave side of the arc or broken line. The vertical line of the center of gravity of the fine-tuning module is a straight line passing through the center of gravity of the fine-tuning module and along the vertical direction of the support component 1, while the vertical line of the center of gravity of the coarse-tuning module is a straight line passing through the center of gravity of the coarse-tuning module and along the support component 1.

[0039] This design greatly enhances the anti-overturning capability and overall stability of the assembly support and adjustment fixture, ensuring safety and stability when adjusting heavy components to be assembled, and providing a solid and reliable foundation for high-precision assembly.

[0040] In a further embodiment, the position of each first vertical adjustment mechanism 2 is adjustable in a direction perpendicular to the vertical direction of the support member 1.

[0041] This design enables the assembly support adjustment fixture provided in this embodiment to flexibly handle components of different shapes and sizes to be assembled. Since components such as the driver's cab headgear and obstacle clearer of rail vehicles often have irregular curved surfaces and structures, their ideal support point positions vary. By adjusting the position of each of the first vertical adjustment mechanisms 2 in the horizontal plane, it can be ensured that the support component 1 can be precisely aligned and act on the most stable and reasonable stress point of the component to be assembled. This greatly improves the versatility and adaptability of the assembly support adjustment fixture, avoiding the need to customize special fixtures for different components to be assembled. It not only ensures the stability and reliability of the support but also significantly reduces manufacturing costs and equipment management difficulty.

[0042] In a specific embodiment, multiple mounting positions can be provided at the top of the fine-tuning device, and the first vertical adjustment mechanism 2 can be fixed to any one of the mounting positions using connecting bolts. By switching the mounting positions of the first vertical adjustment mechanism 2, the position of the first vertical adjustment mechanism 2 can be adjusted.

[0043] In an optional embodiment, each first vertical adjustment mechanism 2 can be slidably connected to the top of the fine adjustment device. Different first vertical adjustment mechanisms 2 can correspond to different sliding tracks. By sliding the first vertical adjustment mechanism 2, the position of the first vertical adjustment mechanism 2 can also be adjusted.

[0044] In this embodiment, the lateral adjustment mechanism includes a first support frame 3, a second support frame 4, and a first drive mechanism 5.

[0045] The first support frame 3 is detachably connected to the coarse adjustment module, and the second support frame 4 is reciprocally slidably disposed on the side of the first support frame 3 away from the coarse adjustment module. The sliding direction of the second support frame 4 relative to the first support frame 3 is along the transverse direction of the support component 1.

[0046] The first drive mechanism 5 is disposed between the first support frame 3 and the second support frame 4, and is used to drive the second support frame 4 to slide back and forth relative to the first support frame 3. It can achieve high-precision and controllable fine-tuning of the position of the support component 1 along its own lateral direction, thereby meeting the stringent requirements for lateral positioning in assembly operations.

[0047] A pair of guide rails are provided between the first support frame 3 and the second support frame 4. The axis of the guide rails is along the transverse direction of the support component 1, which serves as a sliding guide for the second support frame 4 relative to the first support frame 3. This ensures the stability and straightness of the second support frame 4 during the sliding process, avoids jamming or swaying problems, and thus ensures the accuracy and reliability of the transverse adjustment.

[0048] In this embodiment, the longitudinal adjustment mechanism includes a third support frame 6 and a second drive mechanism 7.

[0049] The third support frame 6 is reciprocally slidably disposed on the side of the second support frame 4 away from the first support frame 3, and the sliding direction of the third support frame 6 relative to the second support frame 4 is along the longitudinal direction of the support member 1.

[0050] The second drive mechanism 7 is located between the second support frame 4 and the third support frame 6, and is used to drive the third support frame 6 to slide back and forth relative to the second support frame 4. It can achieve high-precision and controllable fine-tuning of the position of the support component 1 along its own longitudinal direction, and together with the lateral adjustment mechanism, it completes the two-dimensional precise positioning of the component to be assembled in the horizontal plane.

[0051] A pair of guide rails are provided between the second support frame 4 and the third support frame 6. The axis of the guide rails is along the longitudinal direction of the support component 1, which guides the sliding of the third support frame 6 relative to the second support frame 4, ensuring the stability and smoothness of the third support frame 6 during the sliding process, and providing reliable motion guarantee for high-precision longitudinal positioning.

[0052] In this embodiment, the first drive mechanism 5, the second drive mechanism 7, and the first vertical adjustment mechanism 2 all include a lead screw and nut transmission assembly.

[0053] The lead screw and nut drive assembly boasts extremely high transmission precision, accurately converting rotational motion into minute linear displacements. This is the core of the high-precision adjustment capability of the fine-tuning module. Furthermore, the lead screw and nut drive assembly typically possesses excellent self-locking properties, maintaining its current position stably once adjusted, effectively preventing positional shifts in the components being assembled due to their own weight or other factors, thus greatly ensuring the stability and reliability of the support. In addition, the lead screw and nut drive assembly has a simple and compact structure and smooth transmission, which is beneficial for the lightweight design and long-term stable operation of the entire fine-tuning module.

[0054] A rotating handle is installed at the end of the lead screw in the lead screw and nut transmission assembly. The operator applies torque to the lead screw and nut transmission assembly by rotating the rotating handle, so that the lead screw and nut transmission assembly can operate.

[0055] In this embodiment of the invention, the coarse adjustment module includes a movable base and a second vertical adjustment mechanism 8.

[0056] The movable base can move laterally and longitudinally along the support component 1. This enables the assembly support adjustment fixture to move and position rapidly and over a wide range in the horizontal plane, greatly improving the efficiency of initial alignment of the components to be assembled and saving valuable time for subsequent precise adjustments.

[0057] The second vertical adjustment mechanism 8 is mounted on the movable base, and the fine-tuning device is detachably mounted on the output end of the second vertical adjustment mechanism 8. The second vertical adjustment mechanism 8 is used to adjust the position of the fine-tuning module along the vertical direction of the support component 1. The second vertical adjustment mechanism 8 can provide a large stroke vertical lifting capacity, ensuring that the assembly support adjustment fixture can adapt to the operation requirements of different heights. Especially when facing operation scenarios with large space heights, it can quickly lift the components to be assembled to near the target height, ensuring a sufficiently large adjustment range and stronger scene adaptability.

[0058] In this embodiment, the second vertical adjustment mechanism 8 includes a scissor mechanism, the extension and retraction direction of which is along the vertical direction of the support member 1.

[0059] The scissor lift mechanism has a stable structure and a large stroke range, and can be used as the second vertical adjustment mechanism 8 of the coarse adjustment module to achieve a wide range of vertical adjustment. This allows the fine adjustment device and the components to be assembled to be quickly raised and lowered to the approximate working height. This not only ensures a large adjustment range to adapt to the working requirements of different heights, but also provides a basis for the subsequent fine adjustment operation of the fine adjustment module.

[0060] A pair of scissor lift mechanisms are provided, with the plane of the scissor lift mechanisms perpendicular to the longitudinal direction of the support component 1. The pair of scissor lift mechanisms are spaced apart along the longitudinal direction of the support component 1. The top ends of both pairs of scissor lift mechanisms are connected to the first support frame 3 of the fine-tuning device to ensure stable support for the fine-tuning module.

[0061] The detachable connection between the fine-tuning module and the coarse-tuning module can be achieved by detachably connecting the top of the scissor mechanism to the first support frame 3. Specifically, the detachable connection between the scissor mechanism and the first support frame 3 can be achieved using connecting bolts.

[0062] In some implementations, the mobile base includes a base body 9 and wheels 10 located at the bottom of the base body 9. The wheels 10 can drive the base body 9 to move in any direction along the ground. This configuration gives the assembly support adjustment fixture extremely high mobility and flexibility. It can be easily and quickly moved to the designated assembly position by manual pushing without the need for additional lifting equipment. This greatly simplifies the deployment and positioning process of the assembly support adjustment fixture, facilitates large-scale coarse adjustments along the lateral and longitudinal directions of the support component 1, and significantly improves overall work efficiency and ease of operation.

[0063] It should be noted that the aforementioned traveling wheel 10 is equipped with a braking assembly to selectively limit the rotation of the traveling wheel 10. During assembly operations, the braking assembly is used to brake the traveling wheel 10 to ensure the overall positional stability of the assembly support and adjustment fixture.

[0064] In this embodiment, a protective layer is provided on the outside of the support component 1. The protective layer replaces the support component 1 in contact with the component to be assembled. The protective layer acts as a buffer and isolation layer, effectively preventing scratches and pressure damage to the surface of the component to be assembled, thus ensuring the appearance quality of the component. At the same time, the protective layer also increases the static friction coefficient between itself and the component to be assembled, preventing slippage of the component to be assembled due to vibration or slight displacement during fine-tuning, thereby improving the stability of the support and the reliability of the adjustment process.

[0065] The protective layer can be, but is not limited to, made of rubber.

[0066] When performing assembly operations using the assembly support adjustment fixture provided in this embodiment of the invention, the component to be assembled is first placed on the support component 1 in the non-assembly area. The component is then transferred to the assembly area using a movable base, and its horizontal and vertical positions are roughly adjusted using the movable base and scissor mechanism. The horizontal distance between the component to be assembled and the main structure is observed and confirmed, and the position of the component on the horizontal plane is precisely adjusted using the lateral and longitudinal adjustment mechanisms. Finally, the height position is precisely adjusted using multiple first vertical adjustment mechanisms 2. Throughout the adjustment process, real-time measurements can be taken using measuring tools such as dial indicators to ensure adjustment accuracy.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
