Description

Technical Field

[0001] This utility model relates to the field of leaf spring assembly technology, specifically to an automotive leaf spring processing, assembly, and alignment device. Background Technology

[0002] In the field of automotive leaf spring processing and assembly, precise alignment of the leaf springs is crucial for successful bolt assembly. Currently, the industry primarily employs manual assisted positioning or specialized tooling for leaf spring alignment. Existing technology requires workers to replace corresponding sized specialized positioning components, such as different specifications of stops or clamps, with those for leaf springs of varying widths. These components are first bolted to the assembly platform, and then the leaf spring position is manually adjusted to ensure it conforms to the positioning components.

[0003] This traditional assembly and alignment method has significant shortcomings. First, it requires frequent replacement of specialized limiting components when dealing with leaf springs of different widths. This process necessitates disassembling the old component, installing the new one, and repeatedly calibrating the position, which is not only cumbersome but also consumes a significant amount of adjustment time, drastically reducing the efficiency of adapting to different leaf spring specifications. Second, when manually adjusting the leaf spring position, it is difficult to ensure precise alignment of the left and right sides, easily leading to leaf spring misalignment. This results in difficulties with subsequent bolt assembly and may even require readjustment of the leaf spring position, further extending the assembly cycle. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an automotive leaf spring processing and assembly alignment device. When faced with leaf springs of different widths to be assembled, the operator only needs to rotate the bidirectional lead screw in the mounting base to drive the sliding blocks connected symmetrically on both sides to slide synchronously in opposite directions along the mounting base, quickly adjusting to a position that matches the width of the leaf spring. There is no need to replace the special limiting components that are adapted to different leaf springs, which greatly reduces the difficulty of adjusting leaf springs of different specifications.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: an automotive leaf spring processing and assembly alignment device, including a mounting base, and further including a first limiting component and a second limiting component. The first limiting component is used to limit the left and right sides of the leaf spring and can align the leaf spring. The second limiting component is used to limit the front and rear sides of the leaf spring.

[0006] More preferably, a nut limiting block is placed in the middle of the mounting base, and the nut limiting block has different sizes to limit nuts of different sizes.

[0007] More preferably, the first limiting component includes a sliding block, a lead screw, a mounting plate, and a torsion spring. Several sliding blocks are symmetrically slidably connected to the mounting base, the lead screw is rotatably connected to the mounting base, the sliding blocks and the lead screw are threadedly connected, and several mounting plates are rotatably connected to the corresponding sliding blocks. Each mounting plate is connected to the corresponding sliding block by a torsion spring.

[0008] More preferably, the lead screw is a two-way lead screw.

[0009] More preferably, the ramp is inclined.

[0010] More preferably, the second limiting assembly includes limiting members, a sliding frame, sleeves, fixing rods, and springs. Several limiting members are symmetrically fixed to the mounting base, the sliding frame is slidably connected between the limiting members, several sleeves are symmetrically fixed to the corresponding limiting members, several fixing rods are all fixed to the upper part of the sliding frame, and the fixing rods are slidably connected to the corresponding sleeves. Several springs are symmetrically connected between the sliding frame and the limiting members, and the springs are sleeved on the corresponding sleeves and fixing rods.

[0011] Compared with the prior art, the advantages of this utility model are: when faced with leaf springs of different widths to be assembled, the operator only needs to rotate the bidirectional lead screw in the mounting base to drive the sliding blocks connected symmetrically on both sides to slide synchronously in opposite directions along the mounting base, quickly adjusting to the position that matches the width of the leaf spring. There is no need to replace the special limiting components that are adapted to different leaf springs, which greatly reduces the difficulty of adjusting leaf springs of different specifications.

[0012] When the leaf spring is placed on the mounting base, there is no need to operate the second limiting component. The two sides of the leaf spring will naturally contact the mounting plate on the sliding block. The mounting plate is inclined. This structural design can guide the leaf spring and make it automatically return to the correct placement position without the need for the staff to manually adjust the position of the leaf spring repeatedly to achieve alignment.

[0013] During the leaf spring assembly stage, as workers perform assembly operations, the sliding frame of the second limiting component will automatically be pressed to the appropriate height as the relevant components are pressed down or the leaf spring itself is subjected to force. Workers do not need to stop the assembly operation to manually adjust the position of the sliding frame. During this process, the sliding frame slides down along the limiting component, and the fixed rod on the upper part of the sliding frame slides along the sleeve simultaneously, ensuring that the sliding frame descends smoothly without deviation. The elastic potential energy generated by the compression of the spring between the sliding frame and the limiting component allows the sliding frame to fit tightly against the front and rear sides of the leaf spring, effectively preventing the leaf spring from tilting forward or backward during the assembly process and ensuring assembly accuracy.

[0021] Furthermore, it should be understood in the description of this utility model that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0022] Example: As shown in the attached figure, an automotive leaf spring processing and assembly alignment device includes a mounting base 1 for supporting the leaf spring. Multiple nut limiting blocks with different sizes are placed in the center of the mounting base 1 to limit nuts of different sizes. The device also includes a first limiting component and a second limiting component. The first limiting component limits the left and right sides of the leaf spring and enables alignment. The second limiting component limits the front and rear sides of the leaf spring.

[0023] In this embodiment, specifically, the first limiting component includes a sliding block 2, a lead screw 3, a mounting plate 4, and a torsion spring 5. Several sliding blocks 2 are symmetrically slidably connected to the mounting base 1. The lead screw 3 is rotatably connected to the mounting base 1. The lead screw 3 is a bidirectional lead screw 3. The sliding blocks 2 are threadedly connected to the lead screw 3. Several mounting plates 4 are rotatably connected to the corresponding sliding blocks 2. The mounting plates 4 are inclined and are used to support the left and right sides of the leaf spring, and can align the left and right sides of the leaf spring to facilitate the assembly of the leaf spring. Each mounting plate 4 is connected to a torsion spring 5 between itself and the corresponding sliding block 2.

[0024] Furthermore, the second limiting assembly includes limiting members 6, sliding frames 7, sleeves 8, fixing rods 9, and springs 10. Several limiting members 6 are symmetrically fixed to the mounting base 1, and the limiting members 6 serve as guides. The sliding frames 7 are slidably connected between the limiting members 6, and the sliding frames 7 are used to limit the front and rear sides of the leaf spring to prevent the leaf spring from tilting and affecting the assembly efficiency. Several sleeves 8 are symmetrically fixed to the corresponding limiting members 6, and the sleeves 8 serve as guides. Several fixing rods 9 are all fixed to the upper part of the sliding frames 7, and the fixing rods 9 are slidably connected to the corresponding sleeves 8. Several springs 10 are symmetrically connected between the sliding frames 7 and the limiting members 6, and the springs 10 are sleeved on the corresponding sleeves 8 and fixing rods 9.

[0025] In the above technical solution, when using the automotive leaf spring processing and assembly alignment device, the first limiting component is first adjusted according to the size of the leaf spring to be assembled. The lead screw 3 inside the mounting base 1 is rotated. Since the lead screw 3 is a bidirectional lead screw, its rotation will drive the sliding blocks 2 connected symmetrically on both sides to slide synchronously in opposite directions along the mounting base 1 until the sliding blocks 2 move to a position that matches the width of the leaf spring. Then, the nut to be used is placed in the nut limiting block in the middle of the mounting base 1. Alternatively, a nut limiting block of the appropriate size can be selected according to the size of the nut, thereby limiting the nut and preventing it from rolling away and being lost, thus facilitating the quick assembly of the leaf spring by the workers. Then, the leaf spring is placed directly on the mounting base 1 without operating the second limiting component. The two sides of the leaf spring contact the mounting plate 4 on the sliding block 2. The mounting plate 4 is inclined, which can guide the leaf spring to return to its position automatically. At the same time, the torsion spring 5 between the mounting plate 4 and the sliding block 2 can buffer the impact force when the leaf spring is placed through its own elasticity, avoiding damage caused by rigid collision between the leaf spring and the mounting plate 4, thereby achieving the limiting and alignment of the left and right sides of the leaf spring, laying a precise foundation for subsequent assembly.

[0026] During the leaf spring assembly stage, as workers assemble the placed leaf springs, the sliding frame 7 of the second limiting component is automatically pressed to the appropriate height due to the downward pressure of related components or the force exerted on the leaf spring itself. During this process, the sliding frame 7 slides downwards along the limiting member 6, and the fixing rod 9 on the upper part of the sliding frame 7 slides downwards along the sleeve 8 simultaneously. The spring 10 between the sliding frame 7 and the limiting member 6 is compressed and generates elastic potential energy. At this time, the sliding frame 7 tightly fits against the front and rear sides of the leaf spring, limiting the front-rear direction of the leaf spring and preventing it from tilting during assembly. Furthermore, because the sliding frame 7 is automatically pressed down during the assembly operation, it does not obstruct the removal, placement, or assembly of nuts, ensuring smooth assembly operations.

[0027] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
