Description

Technical Field

[0001] This utility model relates to the field of assembly bracket technology, and in particular to an auxiliary bracket for assembling a semi-trailer suspension system. Background Technology

[0002] The assembly of the semi-trailer suspension system is a key step in the production of the entire vehicle. It involves the positioning and connection of various large and heavy components such as leaf springs and balance shafts. In the current technology, the assembly process mostly relies on fixed tooling or manual cooperation, which has problems such as low positioning accuracy, poor adaptability and high labor intensity. Some existing auxiliary devices have limited functions and cannot cope with the structural differences of suspension systems of different vehicle models, which restricts the further improvement of assembly efficiency and quality.

[0003] Currently, there is a lack of a dedicated assembly bracket that can flexibly adjust the support height and horizontal position and quickly adapt to different suspension components. This results in operators having to frequently adjust the posture of components or use additional tools during the assembly process, which not only increases the complexity of operation but also makes it difficult to ensure the accuracy of the alignment connection between multiple components, directly affecting the assembly quality and production efficiency of the suspension system. Therefore, an auxiliary bracket for the assembly of a semi-trailer suspension system is proposed here. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-8This utility model provides an auxiliary support bracket for assembling a semi-trailer suspension system, including a base plate 1 and a top plate 2. The base plate 1 serves as the basic support structure for the entire device, and its interior has a cavity for accommodating the lifting components. A sliding groove 3 is provided on the upper side of the cavity. A first sliding rod 4 and a second sliding rod 5 are slidably connected to the inner side of the sliding groove 3. This symmetrical arrangement ensures the stability of the lifting process. Limiting plates 7 are fixedly connected to the exterior of both the first sliding rod 4 and the second sliding rod 5, and the limiting plates 7 are slidably connected to the top of the cavity. This limiting structure can prevent the sliding rods from deflecting during movement. Support seats 6 are fixedly connected to the upper ends of both the first sliding rod 4 and the second sliding rod 5. The support seats 6 serve as load-bearing components that transmit the lifting movement to the top plate 2. Connecting parts 8 are fixedly connected to the upper side of the support seats 6 and the bottom of the top plate 2, and a rotating frame 9 is rotatably connected between multiple sets of connecting parts 8. This rotatable connection method can adapt to angle changes during the lifting process.

[0025] like Figures 3-5 As shown, a lifting mechanism is installed inside the base plate 1. The lifting mechanism includes a mounting plate 10, a toothed plate 11, a rotating rod 13, and a gear 14. There are two sets of mounting plates 10, which are fixedly connected to the ends of the first slide rod 4 and the second slide rod 5, respectively, for transmitting power. The toothed plate 11 is fixedly connected to the outside of the mounting plate 10 to convert rotational motion into linear motion. The rotating rod 13 is rotatably connected to the inside of the cavity, and the two sets of mounting plates 10 are arranged in a centrally symmetrical manner around the rotating rod 13. This arrangement ensures the synchronicity of the motion. The gear 14 is fixedly connected to the outside of the rotating rod 13, and the gear 14 meshes with both sets of toothed plates 11 to form a complete transmission system. A drive motor 12 is fixedly connected to the outside of the base plate 1 to provide power for the lifting motion, and the rotating rod 13 is fixedly connected to the end of the output shaft of the drive motor 12 to realize power transmission.

[0026] like Figure 7 as well as Figure 8 As shown, the upper side of the top plate 2 is limited and slidably connected to multiple sets of horizontally arranged sliding plates 15. This multi-set design can adapt to workpieces of different sizes. The upper side of the top plate 2 is provided with a slot 16, and the bottom of the sliding plate 15 is fixedly connected to a locking block 17. The locking block 17 is limited and slidably connected to the inside of the slot 16. This cooperation between the slot 16 and the locking block 17 not only ensures the smooth movement of the sliding plate 15, but also prevents the sliding plate 15 from falling off.

[0027] like Figure 8 As shown, a positioning mechanism is installed between the slide plate 15 and the top plate 2. The positioning mechanism includes positioning holes 22 and fastening bolts 23. The positioning holes 22 are opened on the upper side of the top plate 2, and there are several groups of positioning holes 22 arranged at equal intervals. This equal interval arrangement can achieve precise positioning. The fastening bolts 23 are threadedly connected between the slide plate 15 and one of the groups of positioning holes 22, and reliable fixation is achieved by bolt fastening.

[0028] like Figure 8 As shown, a fixed base 18 is fixedly connected to the upper side of the slide plate 15. The fixed base 18 serves as the basis for the clamping mechanism. A clamping plate socket 19 is slidably connected to the inner side of the fixed base 18. This slidable connection allows for fine adjustment of the clamping position. A clamping mechanism is installed between the clamping plate socket 19 and the fixed base 18. The clamping mechanism includes a screw 20 and a positioning nut 21. The screw 20 is threaded to the outside of the fixed base 18, and the end of the screw 20 is rotatably connected to the outside of the clamping plate socket 19. Rotating the screw 20 can drive the clamping plate socket 19 to move. The positioning nut 21 is threaded to the outside of the screw 20 and abuts against both sides of the fixed base 18. This double locking structure ensures the reliability of the clamping.

[0029] The working principle of this utility model is as follows: This bracket achieves precise positioning and stable support for each component of the suspension system through lifting adjustment and multi-position clamping function. The lifting function of the bracket is realized by the lifting mechanism inside the base plate 1. After the drive motor 12 is started, it drives the rotating rod 13 and gear 14 to rotate. By meshing with the toothed plate 11 at the bottom of the first slide rod 4 and the second slide rod 5, the first slide rod 4 and the second slide rod 5 are driven to move synchronously in opposite directions or in opposite directions along the slide groove 3. The movement is transmitted to the top plate 2 through the support seat 6 and the rotating frame 9, so as to realize the smooth lifting of the working platform.

[0030] Horizontal positioning is achieved through the sliding plate 15 on the top plate 2. After the locking block 17 at the bottom of the sliding plate 15 slides along the slot 16 to the desired position, it is locked by the cooperation of the fastening bolt 23 and the positioning hole 22, which meets the needs of adjusting the installation position of components of different sizes. The clamping operation is performed by the fixed seat 18. By inserting a special clamp into the clamping plate socket 19 and rotating the screw 20 to drive the clamping plate socket 19 to move relative to each other, the clamping of different workpieces can be completed. The positioning nut 21 is used to lock the screw 20 to ensure that the clamping is stable. This structure significantly improves the adaptability and efficiency of the suspension system assembly through flexible adjustment in three-dimensional space.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
