[0031] 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.
[0032] Reference Figures 1-3This utility model provides an embodiment of an adjustable support tooling platform for processing automotive control arms, comprising a base plate 1 and side plates 2. The base plate 1 and side plates 2 together form a stable bottom frame structure, providing basic support and limiting for the entire tooling platform. Two side plates 2 are fixedly connected to the top edge of the base plate 1. A mounting plate 4 is fixedly connected to the middle of the top of the base plate 1. The mounting plate 4 serves as an important intermediate support component, used for installing subsequent guide plates 5 and some components of the lifting assembly. Guide plates 5 are fixedly connected to the outer wall of the mounting plate 4. Guide plates 5 provide sliding guidance for the connecting plate 6 in the lifting assembly, ensuring that the connecting plate 6 can move smoothly along a predetermined direction during lifting. A placement platform 3 is provided between the top of the plates 2. The placement platform 3 is used to support the automotive control arm to be processed. It is a working surface that directly contacts the workpiece. A guide plate 2 8 is fixedly connected to the bottom of the placement platform 3. The guide plate 2 8 cooperates with the guide plate 1 5 to provide sliding guidance for the top of the connecting plate 1 6 in the lifting assembly. A lifting assembly is provided on the top middle side of the base plate 1. The lifting assembly can realize the lifting function of the placement platform 3. By adjusting the height of the placement platform 3, it can adapt to different processing needs and the operating habits of operators. An extension assembly is provided inside the placement platform 3. The extension assembly can adjust the working area of the placement platform 3 according to the size of the automotive control arm, increasing the applicability of the tooling platform.
[0033] Reference Figure 2 The lifting assembly includes multiple connecting plates 6 and multiple connecting plates 7. Connecting plates 6 and 7 are rotatably connected and cooperate to form a foldable or unfoldable structure. The lifting of the placement platform 3 is achieved by changing the angle between them. The outer wall of the bottom connecting plate 6 is slidably connected to the inside of the guide plate 5. The guide plate 5 limits and guides the bottom connecting plate 6, ensuring that it does not shift during lifting. The outer wall of the top connecting plate 6 is slidably connected to the inside of the guide plate 8. The guide plate 8 limits and guides the top connecting plate 6. 5. The synergistic effect ensures the stability and accuracy of the lifting assembly. The outer wall of the bottom connecting plate 2 7 is rotatably connected to the outer wall of the mounting plate 4. The mounting plate 4 provides a rotation support point for the bottom connecting plate 2 7, allowing the connecting plate 2 7 to rotate around this point. The top connecting plate 2 7 is rotatably connected to the bottom of the placement platform 3. The placement platform 3 provides rotation support for the top connecting plate 2 7. The rotation of the connecting plate 2 7 drives the lifting of the placement platform 3. A drive assembly is set between the two bottom connecting plates 2 7. The drive assembly provides power to the lifting assembly, driving the connecting plate 1 6 and the connecting plate 2 7 to move, thereby realizing the lifting of the placement platform 3.
[0034] Reference Figure 3The drive assembly includes a mounting frame 9 and a rack plate 12. The mounting frame 9 is fixedly connected between two connecting plates 7 at the bottom. The mounting frame 9 is used to install the motor 10 and the gear 11, and plays a role in fixing and supporting them. The motor 10 is fixedly connected to the inner wall of the mounting frame 9. The motor 10 serves as the power source of the drive assembly and provides power for the entire drive process. The output end of the motor 10 is fixedly connected to the gear 11. The gear 11 transmits and converts the rotational motion of the motor 10. The rack plate 12 is fixedly connected to the top of the base plate 1. The rack plate 12 and the gear 11 mesh with each other. The rack plate 12 cooperates with the gear 11 to convert the rotational motion of the gear 11 into linear motion, thereby driving the lifting assembly to perform lifting and lowering actions.
[0035] Reference Figure 4 The extension assembly includes two extension plates 13. The outer walls of the extension plates 13 are slidably connected to the inside of the placement platform 3. The extension plates 13 are the main components for expanding the area of the placement platform 3. They can extend out from the inside of the placement platform 3 according to the size requirements of the automotive control arm, thereby increasing the working area of the placement platform 3. The outer walls of the extension plates 13 are provided with multiple fixing holes 14. The fixing holes 14 are used to cooperate with the fixing components. When the extension plates 13 are adjusted to the appropriate position, the fixing components fix the extension plates 13 through the fixing holes 14. The inner wall of the placement platform 3 is provided with fixing components, which are used to fix the adjusted extension plates 13 to ensure that the extension plates 13 remain stable in the expanded state of the placement platform 3.
[0036] Reference Figure 5 The fixing component includes a pull rod 16, the outer wall of which is slidably connected to the inner wall of the placement platform 3. The pull rod 16 is the operating part of the fixing component. By pulling the pull rod 16, the extension plate 13 can be fixed and released. A limit block 17 is fixedly connected to the outer wall of the pull rod 16. The limit block 17 is used to limit the pull rod 16 to prevent it from sliding out of the placement platform 3 and causing the fixing component to lose its function. A spring 18 is sleeved on the outer wall of the pull rod 16. The spring 18 provides the limit block 17 with a reset force. When the operator releases the pull rod 16, the spring 18 can make the limit block 17 automatically reset, thus fixing the extension plate 13.
[0037] Reference Figure 1 , Figure 2 and Figure 4 A baffle 15 is fixedly connected to the outer wall of the fixing hole 14. The baffle 15 is used to limit the workpiece placed on the placement table 3 to prevent it from falling during processing. The bottom of the base plate 1 is provided with support feet, which are used to support the entire tooling platform so that it can be placed stably on the ground or workbench.
[0038] Reference Figure 5The pull rod 16 passes through the placement platform 3 and engages with the fixing hole 14. By engaging the pull rod 16 with the fixing hole 14, the extension plate 13 is fixed, ensuring that the position of the extension plate 13 remains stable after the placement platform 3 is expanded.
[0039] Reference Figure 5 One end of the spring 18 is fixedly connected to the inner wall of the placement platform 3, and the other end of the spring 18 is fixedly connected to the outer wall of the limiting block 17. The two ends of the spring 18 are respectively connected to the inner wall of the placement platform 3 and the limiting block 17, providing the limiting block 17 with a restoring elastic force, so that the pull rod 16 is re-engaged with the fixing hole 14, thereby achieving quick fixation of the extension plate 13.
[0040] Reference Figure 5 The outer wall of the limiting block 17 is slidably connected to the inner wall of the placement platform 3, ensuring that the pull rod 16 can accurately engage and disengage with the fixing hole 14, ensuring the normal operation of the fixing component and the effective fixing and loosening of the extension plate 13.
[0041] Working principle: When the height of the placement platform 3 needs to be adjusted, the motor 10 starts, and the output end of the motor 10 drives the gear 11 to rotate. Since the gear 11 meshes with the rack plate 12, the rotational motion of the gear 11 is converted into linear motion. This linear motion is transmitted to the two bottom connecting plates 7 through the mounting bracket 9, causing the connecting plates 7 to rotate around the rotational connection point with the mounting plate 4. At the same time, the connecting plate 6 and the connecting plate 7 are rotatably connected. The bottom connecting plate 6 slides in the guide plate 5, and the top connecting plate 6 slides in the guide plate 8. As the connecting plate 7 rotates, the angle between the connecting plate 6 and the connecting plate 7 changes, and the entire lifting assembly unfolds or folds, thereby driving the placement platform 3 to rise or fall, thus adjusting the height of the placement platform 3 to meet the needs of different processing operations and the operating habits of operators.
[0042] When the working area of the platform 3 needs to be expanded to accommodate a larger automotive control arm, the operator pulls the lever 16, causing it to overcome the spring force of the spring 18 and disengage from the fixing hole 14 of the extension plate 13. At this time, the extension plate 13 can slide inside the platform 3 and be pulled out to a suitable position according to actual needs. Then, the lever 16 is released, and under the action of the spring 18's return force, the limit block 17 drives the lever 16 to reset, causing it to re-engage in the fixing hole 14, thereby fixing the extension plate 13 in the expanded position and realizing the adjustment of the working area of the platform 3.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
