[0002] In the field of modern automobile manufacturing, the assembly process of automotive L-shaped tie rods is one of the key links to ensure the stable performance of the vehicle's steering system and suspension system. With the continuous development of the automotive industry, the requirements for component assembly accuracy and efficiency are increasing day by day, especially for the assembly process involving complex structural parts, such as the riveted connection between the L-shaped tie rod and the gasket. Its assembly quality and efficiency directly affect the performance and production cost of the entire vehicle. Figure 1 An automotive L-shaped tie rod typically consists of a tie rod 100, a lead screw 101, an inner support tube 102, a turbine shaft 103, a bearing 104, a turbine 105, a gasket 106, a ball head 107, and a special-shaped tube 108. The precise fit of these components places high demands on assembly technology. Therefore, the development of efficient and accurate assembly equipment has become a key focus in the industry.

[0003] To improve the assembly efficiency of L-shaped tie rods, a rotating turntable is typically installed on the workbench, along with multiple assembly stations for automated production. Traditional vertical pressure methods often require the turntable to pause before adjusting the workpiece's position before riveting. Furthermore, the workpiece's position must be restored to its original position after the riveting process is complete, severely limiting production efficiency. Summary of the Invention

[0004] In order to improve production efficiency, the present application provides a gasket riveting device for assembling an L-shaped pull rod for a vehicle.

[0006] By adopting the above technical solution, when the L-shaped pull rod approaches the gasket riveting device with the turntable, the lifting mechanism drives the clamping mechanism and the riveting mechanism to move down synchronously close to the workbench. The clamping mechanism is activated first, accurately clamping the gasket to be riveted and positioning it; then the riveting mechanism applies pressure in a direction parallel to the rotation direction of the turntable to accurately rivet the gasket to the specified position of the screw rod. After the riveting is completed, each actuator is reset in sequence: the riveting mechanism returns to the initial position, the clamping mechanism releases the clamping, and finally the lifting mechanism drives the clamping mechanism and the riveting mechanism to move up and reset to prepare for the next working cycle. In this application, the direction of riveting force is consistent with the direction of rotation of the turntable, which not only achieves seamless connection with the automated conveying system, but also ensures the coordination of actions between workstations during continuous operation, significantly improving the production rhythm and process stability.

[0028] The following is combined with Figure 2-7 This application is described in further detail.

[0029] The embodiment of the present application discloses a gasket riveting device for assembling an L-shaped pull rod for a vehicle.

The clamping mechanism 2 is used to clamp the gasket 106, and the output end of the riveting mechanism 3 can approach the clamped gasket 106 and rivet the gasket 106. The lifting mechanism 1 drives the clamping mechanism 2 and the riveting mechanism 3 to approach the L-shaped tie rod 100, and then the clamping mechanism 2 clamps the gasket 106.

The second mounting plate 122 is fixedly installed on the side of the first mounting plate 121 away from the lifting drive 11, and the length direction of the second mounting plate 122 is perpendicular to the length direction of the first mounting plate 121. One end of the second mounting plate 122 is mounted on the end side of the first mounting plate 121 away from the L-shaped pull rod 100, and the other end of the second mounting plate 122 is connected to one end of the first mounting plate 121, and the other end of the first mounting plate 121 is away from the second mounting plate 122. The plate surface of the second mounting plate 122 is perpendicular to the plate surface of the first mounting plate 121, and the plate surface of the third mounting plate 123 is parallel to the plate surface of the first mounting plate 121. The clamping mechanism 2 is installed between the first mounting plate 121 and the third mounting plate 123, and the pressing mechanism is installed on the side of the second mounting plate 122 away from the clamping mechanism 2. When the L-shaped pull rod 100 approaches the assembly device, the lifting drive 11 drives the lifting plate 12 to approach the L-shaped pull rod 100 to facilitate the subsequent riveting action of the gasket 106.

[0032] Reference Figure 2 and Figure 3 The clamping mechanism 2 includes a bidirectional clamping driver 21, a driver mounting plate 22, a support plate 23, a pad 24, and a clamping claw assembly 25. In this embodiment, the bidirectional clamping driver 21 is configured as a cylinder. The support plate 23 is in the shape of a rectangular plate as a whole, and the length direction of the support plate 23 is parallel to the length direction of the second mounting plate 122. The two ends of the support plate 23 in the length direction are respectively fixedly connected to the end sides of the first mounting plate 121 and the third mounting plate 123 away from the second mounting plate 122. The pad 24 is provided on the side of the support plate 23 close to the second mounting plate 122, and the plate surface of the pad 24 is parallel to the plate surface of the support plate 23. There are two driver mounting plates 22, and one end of the two driver mounting plates 22 is respectively installed on both sides of the length direction of the support plate 23 close to the top of the L-shaped pull rod 100, and the other end of the driver mounting plate 22 is located on the side of the pad 24 close to the second mounting plate 122.

Both ends of the bidirectional clamping driver 21 are mounted between the two driver mounting plates 22, and the bidirectional clamping driver 21 is located on the side of the spacer plate 24 closest to the second mounting plate 122.

[0033] The clamping jaw assembly 25 is located at the output end of the bidirectional clamping driver 21. The clamping jaw assembly 25 includes two sliders 251, two connecting bars 252, and two clamping blocks 253. The two sliders 251 are located on the side of the bidirectional clamping driver 21 near the L-shaped rod 100. One end of each connecting bar 252 passes through the two driver mounting plates 22 and connects to the two output ends of the bidirectional clamping driver 21. The other ends of each connecting bar 252 are connected to adjacent sliders 251, and to the ends of the two sliders 251 facing away from each other. Two clamping blocks 253 are located on the side of each slider 251 near the L-shaped rod 100, with one end of the L-shaped rod 100 clamped between the two clamping blocks 253. When the bidirectional clamping driver 21 begins operation, the connecting bars 252 can move the two sliders 251 closer or farther from each other, thereby moving the two clamping blocks 253 closer or farther from each other.

[0034] Reference Figure 4 and Figure 5The two end surfaces of the two sliders 251 facing away from each other are configured as inclined surfaces of the sliders 251, which are inclined toward the sides of the two sliders 251 facing each other. The two end surfaces of the two clamping blocks 253 facing away from each other are configured as inclined surfaces of the clamping blocks 253, and the inclined surfaces of the sliders 251 and the inclined surfaces of the clamping blocks 253 have the same inclination angle. The two clamping blocks 253 have grooves 2531 on the sides of the two clamping blocks 253 that are away from the sliders 251 and closer to each other. The grooves 2531 have semicircular through-holes 2532 on the sides of the groove walls that are away from the L-shaped pull rod 100 and closer to each other. The groove walls have pressure grooves 2533 along the circumference of the through-holes 2532. When the two clamps 253 are close together, the two through holes 2532 form a circular structure for the screw to pass through, and the two grooves 2531 are used as a receiving space to accommodate the gasket 106, the bearing 104 and the turbine 105. The two pressing grooves 2533 are combined into a hexagonal structure, so that the riveting mechanism 3 can cooperate to rivet the gasket 106 into a hexagonal outer ring with the inner ring close to the screw.

[0035] On this basis, refer to Figure 4 and Figure 5 A sliding plate 254 is also provided on the side of the elevated plate 24 away from the support plate 23. The sliding plate 254 is generally rectangular in shape, with its length parallel to the sliding direction of the slider 251. A sliding groove 2541 is defined along the side of the sliding plate 254 away from the elevated plate 24. A sliding bar 2534 extends from the side of the clamping block 253 near the support plate 23, and the sliding bar 2534 slides within the sliding groove 2541, thereby ensuring the correct movement direction of the clamping block 253. In this embodiment, the sliding groove 2541 is configured as a dovetail groove to further ensure position accuracy.

[0036] Preferably, reference Figure 6 In addition, a guide shaft 2511 is fixedly mounted within one of the sliders 251. Guide shaft 2511 is cylindrical in shape, and its length is parallel to that of slider 251. The other slider 251 has a guide hole 2512 defined along the direction of movement of guide shaft 2511, and guide shaft 2511 is slidably connected within guide hole 2512. By providing a sliding fit between guide shafts 2511 and guide holes 2512, the positional accuracy of the two sliders 251 can be ensured.

[0037] Reference Figure 6 and Figure 7The riveting mechanism 3 includes a gas-liquid booster cylinder 31 and a push block 32. The gas-liquid booster cylinder 31 is fixedly mounted on the side of the second mounting plate 122 away from the clamping mechanism 2. The output end of the gas-liquid booster cylinder 31 passes through the second mounting plate 122 and is connected to a push plate 33. The push plate 33 is arranged between the clamping mechanism and the second mounting plate 122, and the plate surface of the push plate 33 is parallel to the plate surface of the second mounting plate 122. The push block 32 is arranged on the side of the push plate 33 close to the slider 251, and the push block 32 is concave in shape as a whole. The opposite sides of the push block 32 close to the slider 251 are set as first guide surfaces, and the slider 251 and the push block 32 are opposite to each other and the two sides close to the push block 32 are set as second guide surfaces, and the inclination angles of the first guide surface and the second guide surface are the same. When the riveting mechanism 3 is working, the push block 32 moves toward the slider 251, and the first guide surface is in contact with the second guide surface. Since the inclination angles of the two are the same, uniform force can be ensured, avoiding misalignment or unilateral force caused by angle deviation, thereby improving riveting accuracy.

[0038] The implementation principle of a gasket riveting device for assembling an L-shaped pull rod for a vehicle in an embodiment of the present application is as follows: when the L-shaped pull rod 100 is transported to the riveting station along the turntable, the lifting mechanism 1 first drives the clamping mechanism 2 and the riveting mechanism 3 to move downward synchronously close to the workpiece; then the bidirectional cylinder in the clamping mechanism 2 drives the precision V-shaped clamping jaws to close, accurately positioning and clamping the gasket 106; then the gas-liquid booster cylinder 31 is started, pushing the push block 32 with a matching guide surface to apply pressure along the tangential direction of the turntable, and accurately riveting the gasket 106 to the specified position of the screw rod; after the riveting is completed, each actuator is reset in turn, and the lifting mechanism 1 drives the entire module to rise, preparing for the next working cycle; this embodiment adopts a riveting force application method in the same direction as the movement direction of the turntable, so that the riveting operation is perfectly matched with the rotation and conveying rhythm of the assembly line, thereby not only eliminating the waiting time caused by direction differences in traditional processes, but also achieving a natural transition between working processes through the optimization of motion trajectories.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
