[0002] In the field of automobile manufacturing and other related industries, precise assembly of various components and assemblies is of great importance. In particular, edge pressing mechanisms are particularly important in cases where the edges or joints of two or more components need to be firmly pressed together. However, in actual production processes, there are often problems of limited pressing space, especially when dealing with complex shapes or compact structures of automobile components.
[0003] Traditional edge pressing mechanisms are usually designed with straight-line driving mechanisms on both sides for pressing. This design can well complete the pressing task in a space-abundant situation. However, in automobile manufacturing, especially in the assembly process of automobile body, interior parts, engine compartment and other areas, due to the close layout of components and narrow space, traditional pressing mechanisms often have difficulty in use. For example, in some cases, one side of the pressing mechanism may be blocked by other components, making it impossible to install or use traditional pressing devices.
[0004] In addition, due to space limitations, traditional pressing mechanisms may not be able to provide sufficient pressing force or may not be able to apply pressing force in a stable manner. This may result in poor component assembly, such as edge misalignment, poor sealing or component damage, thereby affecting the overall performance and quality of the automobile. SUMMARY

DETAILED DESCRIPTION
[0019] The application will be further described in detail below with reference to the accompanying drawings.
[0020] As Figs. 1-3As shown, a kind of edge pressing mechanism, including first pressing piece 1, intermediate connecting piece 3, second pressing piece 2, first power cylinder 4 and second power cylinder 5, first pressing piece 1 is connected with first pressing block 62;Intermediate connecting piece 3 is connected with first lever block 72, and intermediate connecting piece 3 and first pressing piece 1 are rotatably connected;Second pressing piece 2 and intermediate connecting piece 3 are rotatably connected, and second pressing piece 2 is connected with second pressing block 61 and second lever block 71, second pressing block 61 and first pressing block 62 are oppositely arranged, and second lever block 71 and first lever block 72 are oppositely arranged;The cylinder body of first power cylinder 4 and intermediate connecting piece 3 are rotatably connected, the piston rod of first power cylinder 4 and second pressing piece 2 are rotatably connected, and second lever block 71 is located between first power cylinder 4 and second pressing block 61;The cylinder body of second power cylinder 5 and first pressing piece 1 are rotatably connected, the piston rod of second power cylinder 5 and intermediate connecting piece 3 are rotatably connected, and first pressing piece 1, first power cylinder 4 and second power cylinder 5 are all located on the same side of second pressing piece 2.
[0021] In initial state, edge pressing mechanism is in unpressing state, and there is a certain gap between first pressing block 62 and second pressing block 61, allowing the component to be pressed to be put in. The piston rod of first power cylinder 4 and second power cylinder 5 is in initial position, and no pressing force is applied.
[0022] When the component needs to be pressed, first power cylinder 4 and second power cylinder 5 start working at the same time.
[0023] Among them, the piston rod of first power cylinder 4 extends, pushes second pressing piece 2 to rotate around the rotation point of second pressing piece 2 and intermediate connecting piece 3. Because second lever block 71 is located between first power cylinder 4 and second pressing block 61, this rotation will cause second pressing block 61 to approach first pressing block 62, and apply pressing force.
[0024] At the same time, the piston rod of second power cylinder 5 also extends, and pushes intermediate connecting piece 3 to rotate around the rotation point of intermediate connecting piece 3 and first pressing piece 1. This rotation not only directly affects the position of second pressing piece 2, but also produces a certain traction or support effect on first pressing piece 1 through the interaction of intermediate connecting piece 3 and first lever block 72, although first lever block 72 may not directly participate in the direct transmission of pressing force in this design, but it plays a role in balancing and stabilizing the whole pressing mechanism in structure.
[0025] In another way, the piston rod of first power cylinder 4 extends, pushes second pressing piece 2 to rotate around the rotation point of second pressing piece 2 and intermediate connecting piece 3, that is, Fig. 2 Second pressing piece 2 rotates counterclockwise, and at this time, second lever block 71 and first lever block 72 abut, and second lever block 71 acts as a lever fulcrum, so that second pressing block 61 approaches first pressing block 62 to form pressing.
[0026] And the piston rod of the first power cylinder 4 extends to the intermediate connecting piece 3 a clockwise rotation tendency at the Fig. 2 intermediate connecting piece 3 and the second pressing piece 2 rotation point.
[0027] At the same time, the piston rod of the second power cylinder 5 extends to the intermediate connecting piece 3 a counterclockwise rotation tendency at the Fig. 2 second connecting point 312, which offsets the clockwise rotation tendency provided by the first power cylinder 4. And this counterclockwise rotation tendency acts on the first lever block 72 and the first pressing block 62, forming a fulcrum and pressing.
[0028] With the continuous extension of the piston rods of the first power cylinder 4 and the second power cylinder 5, the first pressing block 62 and the second pressing block 61 gradually contact the parts to be pressed, until the predetermined pressing force is reached. At this time, the pressing mechanism reaches a balanced state, and the sum of all forces and torques acting on the mechanism is zero.
[0029] The thrust generated by the first power cylinder 4 is transmitted to the second pressing piece 2 through the piston rod, and then through the rotational connection between the second pressing piece 2 and the intermediate connecting piece 3, it is converted into the pressing force on the second pressing block 61.
[0030] The thrust generated by the second power cylinder 5 is transmitted to the intermediate connecting piece 3 through the piston rod, although it does not directly act on the pressing block, but through adjusting the position and posture of the intermediate connecting piece 3, it indirectly affects the distribution and size of the pressing force.
[0031] Further, the intermediate connecting piece 3 has a first edge 31 and a second edge 32 parallel to the first edge 31; the first edge 31 has a first connecting point 311 and a second connecting point 312, and the first edge 31 is rotatably connected to the first pressing piece 1 and the second power cylinder 5 at the first connecting point 311 and the second connecting point 312 respectively; the second edge 32 has a third connecting point 321 and a fourth connecting point 322, and the second edge 32 is rotatably connected to the second pressing piece 2 and the first power cylinder 4 at the third connecting point 321 and the fourth connecting point 322 respectively.
[0032] Further, the intermediate connecting piece 3 is a plate-shaped polygonal structure, and the intermediate connecting piece 3 is hollow.
[0033] The plate-shaped polygonal structure has high rigidity and stability, can withstand large pressing force and torque, and ensures the stability and reliability of the pressing mechanism during long-term use. Compared with circular or other shapes, the polygonal structure has better torsional performance, can resist the torsional moment generated by the pressing force, and prevent the mechanism from deforming or damaging.
[0034] The hollow arrangement effectively reduces the weight of the intermediate connecting piece 3, reduces the load of the entire pressing mechanism, and improves the dynamic response speed and flexibility of the mechanism. Lightweight design also helps to reduce energy consumption and cost, in line with the requirements of modern industry for energy saving and environmental protection.
[0035] Specifically, the first pressing block 62 and the second pressing block 61 are both in the shape of an "L"; the first pressing block 62 includes a first fixed edge 621 and a first pressing edge 622, and the first fixed edge 621 is connected to the first pressing piece 1; the second pressing block 61 includes a second fixed edge 611 and a second pressing edge 612, and the second fixed edge 611 is connected to the second pressing piece 2, and the second pressing edge 612 is arranged opposite to the first pressing edge 622.
[0036] Specifically, the first lever block 72 and the second lever block 71 are also both in the shape of an "L"; the first lever block 72 includes a first positioning edge 721 and a first lever edge 722, and the first positioning edge 721 is fixedly connected to the intermediate connecting piece 3; the second lever block 71 includes a second positioning edge 711 and a second lever edge 712, and the second positioning edge 711 is fixedly connected to the second pressing piece 2; the second lever edge 712 is arranged opposite to the second lever edge 712.
[0037] The "L"-shaped pressing block design allows the pressing edge to closely fit the edge of the component to be pressed, providing uniform pressing force and preventing deformation or damage of the component during pressing. By adjusting the "L"-shaped structure of the pressing block, it is easier to press components of different shapes and sizes, improving the versatility and adaptability of the pressing mechanism. The "L"-shaped lever block design increases the contact area with the connecting piece, improving the stability and reliability of the connection. Especially during the pressing process, the lever block can more effectively transfer and distribute the pressing force, preventing structural damage due to excessive local stress. The "L"-shaped structural design of the pressing block and lever block allows them to maintain sufficient strength while reducing the occupied space, improving the compactness and flexibility of the overall layout. This is particularly important for pressing mechanisms that require compact installation, saving valuable installation space and reducing manufacturing costs. The "L"-shaped structure makes it easier to connect and disassemble the pressing block and lever block with the corresponding components, simplifying the installation and maintenance process. Especially when replacing the pressing block or lever block, this design can save a lot of time and labor costs, improving work efficiency.
[0038] The embodiments of the specific implementation are the preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so: any equivalent changes made according to the structure, shape, principle of the utility model should be covered within the protection scope of the utility model.
