Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

It is connected to a mounting frame 12, and two sliders 13 are slidably connected inside the two mounting frames 12. A connecting rod 14 is provided between the slider 13 and the damping rod 9, and a spring 2 15 is provided between the two sliders 13. A lubrication assembly is provided on the top right side of the tooling body 1, and the lubrication assembly is used to reduce the friction between the X-axial positioning shaft 5 and the tooling body 1. A cylinder connecting valve 25 is provided on the left side of the automatic rotating cylinder 2, and a positioning grating 26 is provided on the top of the automatic rotating cylinder 2. One end of the spring 10 is fixedly connected to the bottom of the damping rod 9, and the other end of the spring 10 is fixedly connected to the top of the base plate 11. One end of the connecting rod 14 is rotatably connected to the outside of the damping rod 9, and the other end of the connecting rod 14 is rotatably connected to the outside of the slider 13. A spring 2 15 is fixedly connected between the two sliders 13.

[0032] Specifically, the tooling body 1 serves as the basic framework of the entire device. The tooling body 1 provides a stable support structure, ensuring the stability and rigidity of the device, and providing a solid foundation for the installation and operation of other components. The automatic rotating cylinder 2 is located on the left side of the tooling body 1 and is the key power source for realizing the flipping of the oil pipe connector. It drives the positioning clamping shaft 3 to rotate through precisely controlled air pressure changes, thereby driving the oil pipe connector to complete the required flipping action. When processing a single-sided hole, it can ensure that the center positions of the holes on both sides of the product are unified and the hole concentricity is qualified. The positioning clamping shaft 3 is tightly connected to the output end of the automatic rotating cylinder 2 and is responsible for clamping and positioning the oil pipe connector. The positioning part 4 is fixed to the right side of the positioning clamping shaft 3 to assist in positioning the oil pipe connector and ensure that its position is accurate during the flipping process. The X-axis positioning shaft 5 is connected to the positioning part 4 to provide X-axis positioning function, further enhancing the oil pipe connector. In order to ensure stability during the machining process, the axial positioning shaft 7 is connected to the output end of the electric push rod 6. When the oil pipe link rotates 180°, this position automatically rises and contacts the oil pipe link according to the set position, playing an auxiliary positioning role of the oil pipe link, thereby ensuring the stability of the oil pipe link hole measurement machining. The buffer plate 8 is fixed at the bottom of the tooling body. As a preliminary absorber of vibration, it can effectively reduce the impact of the vibration generated by the automatic rotating cylinder 2 when it is working on the tooling body. The damping rod 9 surrounds the bottom of the buffer plate 8 and cooperates with the spring 10 to form an efficient vibration damping system. The damping rod 9 absorbs and dissipates vibration energy through the fluid resistance inside it, while the spring 10 produces elastic deformation under the action of vibration, provides a reaction force, and jointly reduces the impact of vibration on the device. The base plate 11 serves as a fixed base for the damping rod 9 and the spring 10. The base plate provides a stable support to ensure the effective operation of the vibration buffer system. The mounting frame 12 is located on both sides of the top of the base plate 11, providing a sliding track for the slider 13, ensuring that the movement of the slider 13 is smooth and precise. The slider 13 slides inside the mounting frame 12 and is linked to the damping rod 9 through the connecting rod 14. The movement of the slider 13 can absorb and disperse the vibration energy transmitted by the damping rod 9. The connecting rod 14 serves as a bridge between the slider 13 and the damping rod 9. The connecting rod 14 allows the slider 13 to move accordingly with the vibration of the damping rod 9, thereby enhancing the flexibility and response speed of the entire vibration buffering system. The spring 2 15 is fixed between the two sliders 13 and is coordinated with the movement of the slider 13. The spring 2 15 provides additional buffering force through its own elastic deformation, further enhancing the ability to absorb vibration. The cylinder connecting valve 25 is connected to the left side of the automatic rotating cylinder 2, and is used to adjust and control the air pressure input of the cylinder to ensure that the cylinder can accurately perform the flipping task according to the established program. The positioning grating 26 is set on the top of the automatic rotating cylinder 2. As a high-precision position detection sensor, the positioning grating 26 monitors the position of the oil pipe link in real time to ensure its positioning accuracy during the processing.

[0033] Reference Figure 1 and Figure 4 The lubrication assembly includes a storage box 16 and a pump box 17. The bottom of the storage box 16 is fixedly connected to the top of the tooling body 1, the bottom of the pump box 17 is fixedly connected to the top of the tooling body 1, and a push rod 18 is slidably connected to the inside of the pump box 17. A piston 19 is fixedly connected to the left side of the push rod 18. Two springs three 20 are provided inside the pump box 17. An oil extraction pipe 21 is fixedly connected to the rear side of the pump box 17. The oil extraction pipe 21 is fixedly connected to the front side of the storage box 16 at one end away from the pump box 17. An oil delivery pipe 22 is fixedly connected to the left side of the pump box 17. The oil delivery pipe 22 is away from the pump box 17 at one end. The end of the oil delivery pipe 22 is arranged inside the tooling body 1 and is located at the top of the X-axial positioning shaft 5. A handle 23 is fixedly connected to the rear side of the push rod 18. A one-way valve 24 is provided on the outside of the oil delivery pipe 22 and the oil extraction pipe 21. One end of the spring three 20 is fixedly connected to the right side of the piston 19, and the other end of the spring three 20 is fixedly connected to the inner wall of the pump box 17. The outside of the piston 19 is slidably connected to the inside of the pump box 17.

[0034] Specifically, the storage box 16 serves as a storage room for the lubricating oil. The storage box 16 is located on the top of the tool body 1. It provides sufficient capacity to store the required lubricating oil. The pump box 17 is adjacent to the storage box 16. The pump box is the core part of the lubricating oil delivery system. The push rod 18 is slidably connected inside the pump box 17. The push rod 18 is operated by an external handle 23 to realize the extraction and injection of lubricating oil. The piston 19 is fixed to the left side of the push rod 18. The piston 19 reciprocates inside the pump box 17. Through its sealing performance, the pumping of the lubricating oil is realized. Two springs 20 are provided inside the pump box 17. One end of the spring 20 is fixed to the right side of the piston 19, and the other end is fixed to the inner wall of the pump box 17. The one-way valve 24 is respectively arranged on the outside of the oil delivery pipe 21 and the oil extraction pipe 22. The function of the one-way valve 24 is to ensure that the flow direction of the lubricating oil in the pipeline is single, to prevent the lubricating oil from flowing back when it is not needed, and to ensure the efficient operation of the lubrication system.

[0035] Working principle: When the automatic rotating cylinder 2 is working, it will generate vibration, which will be transmitted to the damping rod 9 through the buffer plate 8, and at the same time squeeze the spring 10 to generate elastic force. Then, the connecting rod 14 is driven to rotate through the damping rod 9. The rotation of the connecting rod 14 drives the slider 13 to slide inside the mounting frame 12 and compress the spring 2 15. The elastic force generated by the spring 10 and the spring 2 15 and the damping force of the damping rod 9 buffer the impact force of the equipment body.

[0036] When it is necessary to reduce the friction between the positioning clamping shaft 3 and the tooling body 1, first pull the push rod 18 to drive the piston 19 to move synchronously, and compress the spring three 20 to make the spring three 20 generate elastic force. At this time, the one-way valve 24 on the oil extraction pipe 21 opens automatically, and the lubricating oil inside the storage box 16 is extracted to the inside of the pump box 17 through the oil extraction pipe 21 to complete the oil extraction. When filling the oil, the push rod 18 is pushed to move under the elastic force of the spring three 20, and the piston 19 is driven to move synchronously at the same time. At this time, the one-way valve 24 on the oil delivery pipe 22 opens automatically, and the lubricating oil in the pump box 17 is delivered to the X-axial positioning shaft 5 through the oil delivery pipe 22, thereby reducing the friction between the X-axial positioning shaft 5 and the tooling body 1.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
