Description

Technical Field

[0001] This utility model relates to the field of train assembly technology, specifically to an assembly tooling for the production of rail vehicle bogies. Background Technology

[0002] Bogies are key components of rail vehicles (such as trains, subways, and high-speed trains), mainly used to support the car body, transmit loads, guide, traction, and brake.

[0003] During the assembly of bogies, the frame needs to be hoisted onto two sets of wheelsets for positioning and installation. However, the wheelsets are prone to lateral displacement on the guide rails due to external forces, resulting in wheel track deviation. This necessitates repeated alignment calibration during frame hoisting, which not only increases the workload of manual adjustment but also poses safety risks due to the relative swaying of the frame and wheelsets during frequent hoisting and adjustment, potentially leading to component collisions or personnel injuries. Therefore, this utility model provides an assembly fixture for the production of railway vehicle bogies to solve the aforementioned problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, an assembly fixture for producing a rail vehicle bogie includes a floor 1 and an assembly plate 2. The assembly plate 2 is installed on the floor 1. Guide rails 3 are provided on both the floor 1 and the assembly plate 2. The guide rails 3 enable the wheelset to move on the floor 1 and the assembly plate 2. At the same time, the guide rails 3 also enable the bogie to move to the next area after assembly via the wheelset.

[0022] A frame support component is installed at the top center of the assembly plate 2. The frame support component can effectively support and limit the frame before assembly, making it convenient to adjust and inspect the frame before assembly.

[0023] Wheelset limiting components are installed on both sides of the top of the assembly plate 2. The wheelset limiting components can effectively squeeze from the inside of the wheelset, thereby limiting the movement of the wheelset and thus achieving the effect of limiting the wheelset.

[0024] An adjustment component is installed in the middle of the wheelset limiting assembly. The top of the adjustment component is connected to the frame support assembly. When the frame support assembly is raised or lowered, it drives the wheelset limiting assembly to adjust through the adjustment component. When the frame support assembly rises, the wheelset limiting assembly will press against the wheelset. Conversely, when the frame support assembly descends, the wheelset limiting assembly will separate from the wheelset, thus no longer restricting the wheelset.

[0025] The frame support assembly includes a lifting adjustment device 4, a lifting base plate 5, and a support plate 6. The lifting adjustment device 4 is installed in the middle of the assembly plate 2. The lifting base plate 5 is installed at the output end of the lifting adjustment device 4. The support plate 6 is fixedly installed at the top of the lifting base plate 5. The support plate 6 is raised by controlling the lifting adjustment device 4. After the frame is placed on the support plate 6 and adjusted and inspected, the support plate 6 is lowered by controlling the lifting adjustment device 4 again, thereby driving the frame to be installed on the two sets of wheelsets. The bottom end of the lifting base plate 5 is connected to the adjustment assembly.

[0026] The wheelset limiting assembly includes a pressing rod 9 and a pressing block 10. The pressing rod 9 is installed on the front and rear sides of the adjusting assembly, and the pressing block 10 is installed on the end of the pressing rod 9 away from the adjusting assembly. The adjusting assembly controls the pressing rod 9 to move the pressing block 10 closer to or further away from the inner end of the wheelset, thereby completing the limiting or contact limiting of the wheelset.

[0027] The adjustment assembly includes a protective box 8, an active component, an auxiliary component, and an adjustment component. The protective box 8 is fixedly installed on the top of the assembly plate 2. The interior of the protective box 8 is hollow, and the end of the extrusion rod 9 away from the extrusion block 10 slides through the corresponding position wall of the protective box 8 and extends into the interior of the protective box 8. The active component is installed on the frame support assembly. Specifically, the active component is installed at the bottom of the lifting base plate 5. The bottom of the active component extends through the corresponding position wall of the protective box 8 and into the interior of the protective box 8. The auxiliary component is movably installed inside the protective box 8. The auxiliary component is located in the middle position inside the protective box 8. The auxiliary component and the active component are connected to each other. By adjusting the lifting of the active component, the auxiliary component can be adjusted to rotate appropriately inside the protective box 8. The adjustment component is installed inside the protective box 8 at a position close to each other. The adjustment component and the auxiliary component are connected to each other. By adjusting the auxiliary component, the adjustment component can drive the two sets of extrusion rods 9 to move towards or away from each other.

[0028] The active component includes a lifting plate 14 and a lifting toothed plate 15. The lifting plate 14 is fixedly installed on the frame support assembly. Specifically, the lifting plate 14 is fixedly installed on the bottom wall of the lifting base plate 5. The bottom of the lifting plate 14 extends through the corresponding position wall of the protective box 8 into the interior of the protective box 8. The lifting toothed plate 15 is fixedly installed on one side of the bottom end of the lifting plate 14. The lifting toothed plate 15 is provided with teeth on the side near the auxiliary component.

[0029] The auxiliary component includes a movable shaft 16, a driving gear 17, and a driven gear 18. The movable shaft 16 is horizontally arranged inside the protective box 8, and its two ends are movably mounted on the side wall of the protective box 8. The driving gear 17 is fixedly mounted on the side wall of the movable shaft 16, and the driving gear 17 is connected to the driving component. Specifically, the driving gear 17 and the lifting gear plate 15 are meshed together. The lifting gear plate 15 moves up and down, causing the lifting gear plate 15 to drive the movable shaft 16 to rotate through the driving gear 17. The driven gear 18 is fixedly mounted on the side wall of the movable shaft 16, and the driven gear 18 is connected to the adjusting component. The rotation of the movable shaft 16 causes the movable shaft 16 to drive the driven gear 18 to rotate, thereby driving the adjusting component to adjust, so that the two sets of extrusion rods 9 move to one side away from or close to each other.

[0030] The adjusting component includes a translational toothed plate 19 and a limiting groove 20. The translational toothed plate 19 is fixedly installed on the side wall of the extrusion rod 9 away from the extrusion block 10. The limiting groove 20 is opened on the side wall of the extrusion rod 9 away from the extrusion block 10. The translational toothed plates 19 and limiting grooves 20 on the side walls of the two sets of extrusion rods 9 are close to each other and correspond to each other. That is, the translational toothed plates 19 on one set of extrusion rods 9 correspond to the limiting grooves 20 on the other set of extrusion rods 9. The inner size of the limiting groove 20 is adapted to the size of the translational toothed plate 19. The auxiliary component is located between the two sets of translational toothed plates 19 and is connected to the two sets of translational toothed plates 19. Specifically, the driven tooth 18 on the movable shaft 16 is located between the two sets of translational toothed plates 19 and is meshed with the two sets of translational toothed plates 19. By rotating the driven tooth 18, the driven tooth 18 drives the translational toothed plate 19 to move and adjust accordingly, thereby driving the extrusion rod 9 to move and adjust accordingly.

[0031] The frame support assembly also includes slots 7, which are located on both sides of the top of the tray 6. The shape and size of the slots 7 are adapted to the shape and size of the middle position at the bottom of the frame. The slots 7 enable the frame support assembly to position and support the frame, which can reduce the need to adjust the frame during assembly.

[0032] The wheelset limiting assembly also includes a support frame 11, which is fixedly installed on the top of the assembly plate 2 at the position corresponding to the extrusion rod 9. The inner diameter of the support frame 11 is adapted to the outer diameter of the extrusion rod 9. The extrusion rod 9 is fitted onto the support frame 11. The support frame 11 limits the extrusion rod 9 when it moves, preventing the extrusion rod 9 from moving or deviating.

[0033] The wheelset limiting assembly also includes a rubber pad 12 and a locking rod 13. The rubber pad 12 is in the shape of a rubber plate and is fixedly installed on the side of the extrusion block 10 away from the extrusion rod 9. The rubber pad 12 can increase the friction between the extrusion block 10 and the wheelset when the extrusion block 10 extrudes the wheelset, thereby improving the limiting effect on the wheelset. The locking rod 13 is fixedly installed at both ends of the side of the extrusion block 10 away from the extrusion rod 9. The distance between the two sets of locking rods 13 is compatible with the cross-sectional length when the wheelset and the locking rod 13 are at the same height after the wheelset is installed on the guide rail 3. The two sets of locking rods 13 can effectively lock the two sides of the wheelset, thereby further improving the limiting effect on the wheelset.

[0034] The working principle of this utility model is as follows:

[0035] In use, the two sets of wheelsets are placed on the guide rail 3 and moved to the corresponding wheelset limiting component position on the assembly plate 2. At this time, the lifting adjustment device 4 is activated, driving the support plate 6 to rise to the predetermined position. When the support plate 6 rises, the lifting base plate 5 will drive the active component to move upward for adjustment. Through the lifting tooth plate 15 and the active tooth 17, the auxiliary component will be adjusted through the driven tooth 18 and the translation tooth plate 19, thereby driving the two sets of extrusion rods 9 to move away from each other, so that the two sets of extrusion blocks 10 extrude and limit the wheelsets from the inside of the wheelsets. At the same time, the frame is... After being hoisted and moved onto the pallet 6, and after adjustments and maintenance are completed on the pallet 6, the pallet 6 is lowered by the lifting adjustment device 4. At this time, the frame will be snapped onto the wheelset first. As the pallet 6 moves downward, the lifting base plate 5 will drive the active component to move downward for adjustment. Through the lifting tooth plate 15 and the active tooth 17, the auxiliary component will be adjusted by the driven tooth 18 and the translation tooth plate 19, thereby driving the two sets of extrusion rods 9 to move closer to each other, so that the two sets of extrusion blocks 10 no longer extrude and limit the wheelset, thus completing the assembly operation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
