[0001] This application belongs to the field of intake and exhaust rocker arm technology, specifically a limit adjustment structure for an intake and exhaust rocker arm. Background Technology

[0002] A limit adjustment structure for intake and exhaust rocker arms can precisely control the stroke range of the rocker arm, thereby ensuring the accuracy and stability of the intake and exhaust process. During engine operation, the accuracy of intake and exhaust timing directly affects combustion efficiency and engine performance. The limit adjustment structure can adjust the rocker arm stroke within a certain range, ensuring that the opening and closing time and angle of the intake and exhaust valves are always at their optimal state. Secondly, the limit adjustment structure can effectively reduce excessive wear on engine components, extending the service life of the rocker arm and related components. By controlling the maximum deflection angle of the rocker arm, unnecessary wear caused by overload operation is avoided, improving the engine's durability and reliability.

[0003] The limit adjustment structure also possesses excellent adaptability, allowing for flexible adjustment to meet the needs of different engines and making it suitable for various engine designs and operating conditions. It can adjust the intake and exhaust timing according to different engine operating conditions to optimize fuel consumption and emissions performance, thereby achieving higher fuel efficiency and lower harmful emissions to meet increasingly stringent environmental standards.

Utility Model Content

[0005] The purpose of this application is to provide a limit adjustment structure for an intake and exhaust rocker arm in order to solve the problem of the aforementioned exhaust rocker arm assembly with adjustable height.

[0006] The technical solution adopted in this application is as follows: A limit adjustment structure for an intake and exhaust rocker arm includes a frame plate. A rectangular groove is provided on the side of the frame plate. A bottom ring plate is fixedly connected inside the rectangular groove. A rotating screw is threaded to the upper end of the bottom ring plate. A handle is fixedly connected to the other end of the rotating screw through the frame plate. A movable plate is threaded to the side of the rotating screw. A handle is fixedly connected to the side of the movable plate. A through groove is provided on the side of the frame plate adjacent to the rectangular groove. A side bolt is provided inside the through groove. The other end of the side bolt is threaded to the movable plate through the through groove.

[0007] By adopting the above technical solution, during the use of the structure, the operator can rotate the handle to drive the rotating screw, thereby adjusting the working position of the movable plate set on the side of the rotating screw. By rotating the screw clockwise or counterclockwise, the position of the movable plate can be adjusted downwards or downwards, which is convenient for adjustment according to different usage requirements. The adjustment of the vertical position can finely adjust the working position of the rocker arm, thereby accurately controlling the timing of air intake and exhaust, further optimizing the air intake and exhaust efficiency of the subsequent structure, and facilitating operation under different speed and load conditions. When adjusting, the operator loosens the side bolts so that the side bolts are away from the frame plate, and then holds the handle to rotate, driving the rotating screw to adjust the working position of the movable plate, which is convenient for subsequent adjustment of the working position of the air intake and exhaust rocker arms. After adjustment, the operator tightens the side bolts so that the frame plate is close to the side of the frame plate, thereby helping to limit the position of the movable plate and ensuring the stability of the position of the movable plate and the air intake and exhaust rocker arms.

[0008] In a preferred embodiment, a connecting ring plate is fixedly connected to the lower end of the frame plate, and a rotating disk is fixedly connected to the lower end of the connecting ring plate.

[0009] By adopting the above technical solution, the connecting ring plate is designed to support the position of the frame plate, and the rotating disk is designed to support the position of the connecting ring plate, ensuring the stability of the structure and facilitating subsequent operations.

[0010] In a preferred embodiment, the lower end of the rotating disk is rotatably connected to a rotating base, and the upper end of the rotating base is provided with a plurality of adjustment holes at an adjacent position to the rotating disk.

[0011] By adopting the above technical solution, the rotating base is designed to support the position of the rotating disk, thereby facilitating the subsequent rotation of the rotating disk and allowing for multi-angle adjustment of the working angle of the frame plate, thus increasing the adaptability of the structure.

[0012] In a preferred embodiment, a plurality of rectangular plates are fixedly connected to the side of the rotating disk, and the rectangular plates are internally threaded with fixing bolts. The other end of the rectangular plate passes through the fixing bolts and is inserted into the adjustment hole at the corresponding position on the upper end of the rotating base.

[0013] By adopting the above technical solution, the rectangular plate and fixing bolts facilitate the fixing of the rotating disk position and are used in conjunction with the adjustment by the staff. The other end of the rectangular plate is inserted into the adjustment hole to ensure the stability of the rectangular plate position.

[0014] In a preferred embodiment, the side of the intake and exhaust rocker arm is provided with a plurality of working holes.

[0015] By adopting the above technical solution, the setting of the working hole facilitates the installation of subsequent structures and ensures the stable operation of the intake and exhaust rocker arm.

[0016] In a preferred embodiment, the intake and exhaust rocker arm is composed of multiple layers of materials, and an aluminum alloy layer is disposed inside the intake and exhaust rocker arm.

[0017] By adopting the above technical solution, the aluminum alloy layer is lightweight, high-strength, and has good corrosion resistance, which can effectively reduce the weight of the rocker arm, help dissipate heat, avoid overheating damage, and meet the complex structural design requirements of the intake and exhaust rocker arm.

[0018] In a preferred embodiment, a high-strength steel layer is provided inside the intake and exhaust rocker arm at the lower end of the aluminum alloy layer.

[0019] By adopting the above technical solution, the high-strength steel layer has excellent wear resistance and tensile strength, making it suitable for use in high-load and high-temperature environments. It can provide strong structural stability and is not easily deformed during long-term operation, thus extending the service life of the rocker arm.

[0020] In a preferred embodiment, a titanium alloy layer is provided inside the intake and exhaust rocker arm at the lower end of the high-strength steel layer.

[0021] By adopting the above technical solution, the titanium alloy layer has a very high strength-to-weight ratio. The structure is not only lightweight, but also has excellent corrosion resistance and high-temperature performance, which enables it to maintain good performance even under long-term high-load operation.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, during the use of the structure, the operator can adjust the working position of the movable plate on the side of the screw by rotating the handle. By rotating the screw clockwise or counterclockwise, the position of the movable plate can be adjusted downwards or downwards, facilitating adjustments according to different usage requirements. The adjustment of the vertical position allows for fine adjustment of the working position of the rocker arm, thereby precisely controlling the timing of air intake and exhaust, further optimizing the intake and exhaust efficiency of the subsequent structure, and facilitating operation under different speed and load conditions. When adjusting, the operator loosens the side bolts so that they are away from the frame plate, and then holds the handle to rotate, driving the screw to adjust the working position of the movable plate, facilitating subsequent adjustment of the working position of the intake and exhaust rocker arms. After adjustment, the side bolts are tightened so that the frame plate is tightly attached to the side of the frame plate, thereby helping to limit the position of the movable plate and ensuring the stability of the movable plate and the intake and exhaust rocker arms.

[0026] Reference Figure 1-4A limit adjustment structure for an intake and exhaust rocker arm includes a frame plate 1. A rectangular groove is formed on the side of the frame plate 1. A bottom ring plate 4 is fixedly connected inside the rectangular groove. A rotating screw 13 is threaded to the upper end of the bottom ring plate 4. The other end of the rotating screw 13 passes through the frame plate 1 and is fixedly connected to a handle 2. A movable plate 3 is threaded to the side of the rotating screw 13. The handle 2 is fixedly connected to the side of the movable plate 3. A through groove is provided on the side of the frame plate 1 adjacent to the rectangular groove. A side bolt 14 is provided inside the through groove. The other end of the side bolt 14 passes through the through groove and is threaded to the movable plate 3. In use, the operator rotates the handle 2 to rotate the rotating screw 13, thereby adjusting the working position of the movable plate 3 on the side of the rotating screw 13. The position can be adjusted by rotating the screw 13 clockwise or counterclockwise. The counterclockwise rotation allows for downward or downward adjustment of the position of the movable plate 3, facilitating adjustments based on different usage requirements. This vertical adjustment enables precise control of the rocker arm's working position, thereby accurately controlling the timing of air intake and exhaust, further optimizing the intake and exhaust efficiency of subsequent structures, and facilitating operation under different speed and load conditions. During adjustment, the operator loosens the side bolt 14, moving it away from the frame plate 1, and then rotates the handle 2 to rotate the rotating screw 13, adjusting the position of the movable plate 3. This facilitates subsequent adjustment of the working position of the intake and exhaust rocker arm 12. After adjustment, the side bolt 14 is tightened, ensuring the frame plate 1 is flush against its side, which helps to limit the position of the movable plate 3 and ensures the stability of the movable plate 3 and the intake and exhaust rocker arm 12.

[0027] Reference Figure 1-4 A connecting ring plate 5 is fixedly connected to the lower end of the frame plate 1, and a rotating disk 6 is fixedly connected to the lower end of the connecting ring plate 5. The connecting ring plate 5 is designed to support the position of the frame plate 1, and the rotating disk 6 is designed to support the position of the connecting ring plate 5, ensuring the stability of the structure and facilitating subsequent operations.

[0028] Reference Figure 1-4 The lower end of the rotating disk 6 is rotatably connected to a rotating base 8. The upper end of the rotating base 8 is provided with multiple adjustment holes 7 adjacent to the rotating disk 6. The rotating base 8 is designed to support the position of the rotating disk 6, thereby facilitating the subsequent rotation of the rotating disk 6. It can adjust the working angle of the frame plate 1 at multiple angles, increasing the adaptability of the structure.

[0029] Reference Figure 1-4Multiple rectangular plates 9 are fixedly connected to the side of the rotating disk 6. The internal threads of the rectangular plates 9 are connected to fixing bolts 10. The other end of the rectangular plate 9 passes through the fixing bolts 10 and is inserted into the adjustment hole 7 at the corresponding position on the upper end of the rotating base 8. The rectangular plates 9 and fixing bolts 10 are used to fix the position of the rotating disk 6 and are used for adjustment by the staff. The other end of the rectangular plate 9 is inserted into the adjustment hole 7 to ensure that the position of the rectangular plate 9 is stable.

[0030] Reference Figure 1-4 The intake and exhaust rocker arm 12 has multiple working holes 11 on its side. The working holes 11 facilitate the installation of subsequent structures and ensure the stable operation of the intake and exhaust rocker arm 12.

[0031] Reference Figure 5 The intake and exhaust rocker arm 12 is composed of multiple layers of materials. The interior of the intake and exhaust rocker arm 12 is provided with an aluminum alloy layer 15. The aluminum alloy layer 15 is lightweight, high-strength and has good corrosion resistance, which can effectively reduce the weight of the rocker arm and also help dissipate heat and avoid overheating damage, thus meeting the complex structural design requirements of the intake and exhaust rocker arm.

[0032] Reference Figure 5 The interior of the intake and exhaust rocker arm 12 is provided with a high-strength steel layer 16 at the lower end of the aluminum alloy layer 15. The high-strength steel layer 16 has excellent wear resistance and tensile strength, making it suitable for use in high-load and high-temperature environments. It can provide strong structural stability and is not easily deformed during long-term operation, thus extending the service life of the rocker arm.

[0033] Reference Figure 5 The intake and exhaust rocker arm 12 has a titanium alloy layer 17 located at the lower end of the high-strength steel layer 16. The titanium alloy layer 17 has a very high strength-to-weight ratio, making the structure not only lightweight but also having excellent corrosion resistance and high-temperature performance, which allows it to maintain good performance even under long-term high-load operation.

[0034] The implementation principle of the limiting adjustment structure of the intake and exhaust rocker arm of this application is as follows: In operation, the operator rotates handle 2 to drive the rotating screw 13, thereby adjusting the working position of the movable plate 3 located on the side of the screw 13. Rotating the screw 13 clockwise or counterclockwise adjusts the position of the movable plate 3 downwards or downwards, facilitating adjustments based on different usage requirements. This vertical adjustment allows for precise control of the rocker arm's working position, ensuring accurate control of air intake and exhaust timing and further optimizing the intake and exhaust efficiency of subsequent structures. This facilitates operation under different speeds and loads. During adjustment, the operator loosens the side bolt 14, moving it away from the frame plate 1. Then, by rotating handle 2, the operator drives the rotating screw 13 to adjust the position of the movable plate 3, facilitating subsequent adjustments to the working position of the intake and exhaust rocker arm 12. After adjustment, the operator tightens the side bolt 14, ensuring the frame plate 1 is flush against its side, thus helping to limit the position of the movable plate 3 and ensuring the stability of the movable plate 3 and the intake / exhaust rocker arm 12. This structure allows the rocker arm to adjust its working angle over a wider range, optimizing intake and exhaust pressure and flow, and maintaining the efficient operation of subsequent structures. The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
