Description

Technical Field

[0001] This utility model relates to the field of common rail pipe processing technology, and in particular to a common rail pipe processing fixture. Background Technology

[0002] As a core component of the high-pressure fuel system, the common rail has high requirements for dimensional and geometric tolerances (such as roundness and coaxiality) at its injection holes and mounting surfaces. The fixture uses a positioning datum to prevent workpiece loosening or displacement, ensuring the positional accuracy of the machined features. Simultaneously, cutting forces during machining can cause deformation of thin-walled or complex-structured common rails. The fixture uses rigid clamping (such as hydraulic clamping) to suppress vibration, prevent deformation caused by cutting forces, and ensure uniform wall thickness and smooth internal surface finish.

[0003] In existing technologies, traditional clamping structures often employ rigid clamping methods, which can easily scratch or deform the surface of the common rail pipe during clamping. Especially under high-pressure conditions, long-term use may lead to fatigue damage of the common rail pipe, affecting its sealing performance and service life. Secondly, existing fixtures have limited positioning accuracy, making it difficult to quickly align the joints or lugs on the common rail pipe, resulting in low installation efficiency and potentially affecting the assembly of subsequent components due to positional deviations. Therefore, we propose a common rail pipe machining fixture to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a common rail pipe processing fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A common rail pipe processing fixture includes a mounting base. Two support members are fixedly connected to the top of the mounting base. A cylinder is fixedly connected to the top of the mounting base. A push plate is fixedly connected to the outer wall of the cylinder's output end. Two downward plates are fixedly connected to the outer wall of the push plate. A rectangular block is fixedly connected to the top of each of the two downward plates. An arc-shaped clamping block is fixedly connected to the top of each of the two rectangular blocks. A common rail pipe body is placed on the top of the two support members. Two round rods are fixedly connected to the top of the mounting base. A single pad is fixedly connected to the top of the two round rods. Two pad blocks are fixedly connected to the top of the pad. The two ends of the pad are respectively fixedly connected to the outer walls of the two support members. A positioning component is provided on the outer wall of the push plate.

[0007] Preferably, the positioning component includes two push rods, one end of each push rod is fixedly connected to the outer wall of the push plate, and the other end of each push rod is fixedly connected to the same limiting plate. The common rail tube body is positioned by setting the positioning component.

[0008] Preferably, the outer wall of the mounting base is provided with multiple mounting holes, which facilitates the installation and fixing of the mounting base.

[0009] Preferably, the outer walls of both support members are provided with strip grooves, and the inner walls of the two strip grooves are slidably connected to the outer walls of the two rectangular blocks respectively. By setting the strip grooves, the rectangular blocks are assisted in driving the arc-shaped clamping blocks to move linearly.

[0010] Preferably, both the support member and the outer wall of the arc-shaped clamping block are fixedly connected with arc-shaped rubber blocks, which avoid rigid contact with the common rail pipe body when providing clamping force.

[0011] Preferably, the outer walls of the limiting plate and the two pads are in contact with the outer wall of the common rail pipe body, and the limiting plate and the two pads cooperate to achieve the initial positioning of the common rail pipe body.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses curved rubber blocks for flexible clamping, avoiding scratches or deformation caused by rigid clamping. It is especially suitable for high-pressure conditions and reduces the risk of fatigue damage to the common rail pipe body. Through the coordinated design of support components, limit plates, and pads, the joints or lugs on the common rail pipe body can be quickly aligned, reducing positional deviations, improving assembly efficiency, and ensuring the accurate installation of subsequent components. The cylinder-driven push plate and curved clamping blocks achieve rapid and stable clamping of the common rail pipe body, reducing manual adjustment time and improving production efficiency.
