Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping technology, and in particular to an automatic centering and clamping device for automotive leaf springs. Background Technology

[0002] With the development of the global economy and the improvement of people's living standards, the demand for automobiles, as a representative of modern transportation, continues to grow. According to relevant statistics, the global annual automobile production has remained stable at tens of millions of vehicles in recent years, and the growth in automobile production and sales in emerging market countries is particularly significant. While automobile production continues to grow, competition in the automotive industry is also becoming increasingly fierce. In order to gain a dominant position in the market, major automobile manufacturers are constantly increasing their investment in automobile research and development, production and manufacturing, and quality control. This not only puts forward higher requirements for the production quality and efficiency of automotive parts, but also prompts automotive parts manufacturers to continuously carry out technological innovation and equipment upgrades. In the production and manufacturing process of automotive leaf springs, accurate centering and clamping of the leaf springs is an important prerequisite for the smooth progress of subsequent processing steps.

[0003] The structure of an automatic centering and clamping device for automotive leaf springs includes a support and mounting structure, a clamping mechanism, a centering mechanism, a control system, and auxiliary devices. During the production of automotive leaf springs, various processing operations are required. If the leaf springs are not securely clamped during these operations, they will shift due to external forces, leading to decreased processing accuracy and even rendering them unusable. Existing devices can automatically complete the centering and clamping of automotive leaf springs, significantly reducing the clamping time for each leaf spring compared to traditional manual methods. However, uneven application of the fixing force during the fixing process can cause excessive deformation in localized areas, even resulting in micro-cracks. Over time, and with vibrations during vehicle operation, this can eventually lead to leaf spring breakage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic centering and clamping device for automotive leaf springs, which aims to improve the problem in the prior art where uneven application of fixing force during the fixing process leads to excessive deformation in local areas, or even micro-cracks, which eventually cause leaf springs to break over time and due to vibrations during vehicle operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic centering and clamping device for automotive leaf springs, comprising a base plate, a second support plate fixedly connected to the top right side near the edge of the base plate, a telescopic rod fixedly connected to the left side of the second support plate, a long plate fixedly connected to the other end of the telescopic rod, short plates rotatably connected to the front and rear sides of the long plate, a third support plate fixedly connected to the front and rear sides of the top center of the base plate, an L-shaped block slidably connected to the center of the third support plate, an adjacent side of the L-shaped block rotatably connected to the left side of the short plate, a clamping block fixedly connected to the left side of the L-shaped block, an elastic element fixedly connected to the adjacent side of the clamping block, a worktable fixedly connected to the top left side of the base plate, and a centering mechanism provided on the top of the worktable, the centering mechanism being used to ensure the centering of the automotive leaf spring.

[0006] As a further description of the above technical solution:

[0007] The centering mechanism includes two support plates, the bottom of which is fixedly connected to the front and rear ends of the top left side of the base plate. Each support plate is fixedly connected to a guide post on an adjacent side. The front top of each clamping block has a hole. The top of the worktable is fixedly connected to two guide rails. Each guide rail is slidably connected to a protective block in the middle. The top inner side of each protective block is fixedly connected to a positioning post. Each positioning post is engaged with an automotive leaf spring.

[0008] As a further description of the above technical solution:

[0009] An anti-slip pad is fixedly connected to the bottom of the base plate, and a support frame is fixedly connected to the front right side of the top of the base plate.

[0010] As a further description of the above technical solution:

[0011] Multiple breathing lights are fixedly connected to the top front end of the support frame, and all of the breathing lights adopt a symmetrical design.

[0012] As a further description of the above technical solution:

[0013] A support pad is fixedly connected to the middle of the right side of the top of the base plate, and a sliding groove is provided on the top of the support pad.

[0014] As a further description of the above technical solution:

[0015] A T-shaped block is fixedly connected to the middle of the bottom end of the long plate, and the bottom of the T-shaped block is slidably connected to the inner wall of the groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the telescopic rod drives the long plate to move left and right. The movement of the clamping block, along with the elastic element, completes the fixation of the automotive leaf spring on the top of the workbench. The elastic element plays a buffering and adjusting role during the fixing process, making the force applied by the clamping block to the automotive leaf spring more uniform, ensuring the quality and integrity of the automotive leaf spring. At the same time, the fixing efficiency is higher, which can effectively improve production efficiency and reduce production costs.

[0022] 2. In this utility model, the fixed route is restricted by the guide post on one side of the support plate and the hole on the front side of the clamping block. The centering effect is achieved by the protective block on the top of the guide rail. The positioning post can fix the placement of the automotive leaf spring and prevent the automotive leaf spring from falling off when the guide rail slides. It can ensure that the clamping block can accurately reach the predetermined position every time, thereby improving the assembly accuracy and consistency and reducing the occurrence of leaf spring instability caused by clamping block position deviation.

The movement of the L-shaped block 8 will cause the clamping block 9 connected to it to move. The movement of the clamping block 9 will cause the elastic element 10 to complete the fixation of the automotive leaf spring on the top of the worktable 11. The elastic element 10 can play a buffering and adjusting role in the fixation process, so that the force applied by the clamping block 9 to the automotive leaf spring is more even. It can effectively avoid the problem of deformation or damage of the automotive leaf spring during the fixation process due to excessive local force, thus ensuring the quality and integrity of the automotive leaf spring. At the same time, the fixation efficiency is higher, which can effectively improve production efficiency and reduce production costs.

[0040] The fixed route is restricted by the guide post 202 on the adjacent side of the support plate 201 and the hole 203 on the front side of the clamping block 9. The centering effect is achieved by the protective block 205 on the top of the guide rail 204. The positioning post 206 can fix the placement of the automotive leaf spring 207 and prevent the automotive leaf spring 207 from falling off when the guide rail 204 slides. This ensures that the clamping block 9 can accurately reach the predetermined position every time, thereby improving the assembly accuracy and consistency and reducing the occurrence of leaf spring instability caused by the position deviation of the clamping block 9.

[0041] 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.
