[0002] High-pressure fuel pump, a professional term in the automotive parts industry, is one of the basic components of the fuel injection system in electronic fuel injection vehicles. The fuel pump mount is a structure used to fix and install the high-pressure fuel pump. When grinding and drilling the fuel pump mount, a processing device is required.

[0003] Chinese patent CN214816462U discloses a high-pressure fuel pump seat processing device, including a movable sliding assembly, a rotating fixed seat, a support base, a processing adjustment component, and a processing component. The support base includes a support platform with a through groove in the middle. The lower surface of the support platform has four support feet at the four corners. The movable sliding assembly is slidably connected inside the through groove, and the rotating fixed seat is mounted on the movable sliding assembly. The processing adjustment component is located at the middle of the right end of the upper surface of the support platform. Two processing motors can drive a drilling bit and a grinding disc to rotate respectively. The drilling bit can drill holes in the workpiece, and the grinding disc can grind the workpiece, thus achieving multiple processing operations and providing convenience. This high-pressure fuel pump seat processing device has a simple structure and is easy to operate. It not only makes the processing of workpieces more comprehensive but also allows for multiple processing operations and convenient conversion.

[0004] However, the aforementioned patent describes fixing the high-pressure fuel pump by rotating a fixed base. In actual production, high-pressure fuel pumps are not standardized in model and size, so the device is not widely applicable. When dealing with high-pressure fuel pumps used by the military, the rotating fixed base needs to be replaced multiple times, which reduces production efficiency. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a processing device for a high-pressure fuel pump seat, comprising: a fixed plate 4 and a base plate 5 mounted on a workbench 1; a control switch 2 fixedly connected to one side of the workbench 1, the control switch 2 being able to preset and control the overall operation of the device; a turntable 8 rotatably connected to the upper end of the workbench 1, the turntable 8 being used to place and rotate materials; a processing part 3 and a fixed plate 4 fixedly connected to the upper end of the workbench 1; and two base plates 5, which facilitate adjustment. One base plate 5 is fixedly connected to the upper end of the workbench 1 and parallel to the fixed plate 4, while the other base plate 5 is located between the base plate 5 and the fixed plate 4. At this time, the fixing state of the material can be changed by moving the central base plate 5, and this base plate 5 is slidably connected to the upper end of the workbench 1, thereby improving the overall smoothness.

[0020] Four fixing posts 6 are fixedly connected to one side of the fixing plate 4. The fixing posts 6 can be installed at the corner of the fixing plate 4. The other end of the fixing post 6 passes through two substrates 5 in sequence and is fixedly connected to the last substrate 5. The fixing posts 6 can guide the middle substrate 5. The fixing plate 4 is connected to the nearest substrate 5 through an electric push rod 11. This substrate 5 is fixedly connected to the electric push rod 11. The electric push rod 11 can force the middle substrate 5 to slide. The output end of the electric push rod 11 is fixedly connected to the fixing plate 4. Servo motors 9 are fixedly connected to the sides of the two substrates 5. The servo motors 9 can change the position of the sliders 12. The output end of the servo motors 9 is fixedly connected to a threaded rod 10. The other end of the threaded rod 10 passes through one side of the substrate 5 and is rotatably connected to the inner wall of the substrate 5. The surface of the threaded rod 10 has two reverse threads, which can make the two sliders 12 move in opposite directions.

[0021] Both substrates 5 have grooves 7 on their inner walls. Two sliders 12 are slidably connected to the inner walls of the grooves 7. One end of each slider 12 in the same groove 7 is connected to a different thread on the surface of a threaded rod 10, which facilitates the fixing of materials by the sliders 12. The threaded rod 10 is located in the grooves 7. Several connecting posts 14 are slidably connected to the surfaces of the four sliders 12. The connecting posts 14 guide the flexible plate 13. One end of each connecting post 14 is fixedly connected to a spring 15. The spring 15 is fixedly connected to the inner wall of the slider 12, which facilitates the reset of the flexible plate 13 and allows the flexible plate 13 to fit tightly against the surface of the material. One side of each slider 12 is connected to a flexible plate 13 by several connecting posts 14. The flexible plate 13 is fixedly connected to the connecting posts 14, which buffers the material and prevents damage from direct collision.

[0022] In actual use, after verifying that the device is correct, the high-pressure fuel pump is placed on the upper end of the turntable 8. Then, the electric push rod 11 and the two servo motors 9 are started. At this time, the middle base plate 5 will gradually slide towards the other base plate 5 under the action of the electric push rod 11. At the same time, the slider 12 will gradually approach under the action of the threaded rod 10. When the flexible plate 13 contacts the high-pressure fuel pump, it will compress the spring 15 and thus provide cushioning. After the spring 15 is compressed, the slider 12 will contact the flexible plate 13. The two together exert force on the high-pressure fuel pump to complete the fixation. For high-pressure fuel pumps of different sizes, it is only necessary to adjust the final size between the sliders 12 by controlling the switch 2, thereby enhancing the overall applicability of the device.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
