[0014] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0015] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0016] according to Figures 1-4As shown, a feeding device for a high-pressure transmission pipe for an automotive engine includes a worktable 1. A movable platform 2 is mounted on the worktable 1 via a first guide rail 11, which guides the movement of the platform 2, ensuring smooth and accurate movement along the worktable 1. A rack 12 is also provided on one side of the worktable 1. A movable hydraulic cylinder 3 is mounted on the platform 2, and a servo motor 4 is also mounted on the platform 2 to drive its movement. A piston rod 31 is mounted on the hydraulic cylinder 3, and a gripping device 5 is mounted on the piston rod 31 for gripping... The device 5 includes a sleeve 51, with a piston rod 31 passing through the sleeve 51. Multiple grippers 52 are also provided on the piston rod 31 for gripping the pipe. The grippers 52 are arranged around the piston rod 31 and connected by pins. The gripping device 5 achieves the clamping and releasing of the grippers 52 through the extension and retraction of the piston rod 31. When the piston rod 31 retracts, the grippers 52 clamp; conversely, when it retracts, the grippers 52 release. One end of the gripper 52 connected to the piston rod 31 is located inside the sleeve 51, while the other end is exposed for gripping the pipe. A bushing 54 is provided at the position corresponding to the gripper 52 on the piston rod 31, located at the end of the piston rod 31.

[0017] The movable platform 2 is provided with a second guide rail 21. The hydraulic cylinder 3 is movably mounted on the movable platform 2 via the second guide rail 21, so that the hydraulic cylinder 3 can move laterally along the second guide rail 21 on the movable platform 2, thereby adjusting the position of the clamping device 5 and improving the flexibility and adaptability of the device. The movable platform 2 is also provided with a pair of symmetrically arranged fixing blocks 22. A screw 23 is provided through the fixing blocks 22. The screw 23 passes through the bottom of the hydraulic cylinder 3. A handle is also provided at one end of the screw 23. The operator can adjust the position of the hydraulic cylinder 3 by rotating the handle.

[0018] The servo motor 4 is located on the side where the rack 12 is located. Its movable end passes through the movable platform 2 and is equipped with a drive gear 41 that meshes with the rack 12. The servo motor 4 can drive the movable platform 2 to move along the first guide rail 11.

[0019] The cylinder 3 is provided with a flange 32, and the sleeve 51 is connected to the cylinder 3 through the flange 32.

[0020] The gripper 52 is provided with a return spring 55, which is connected to the piston rod 31. The end of the gripper 52 is also provided with an anti-slip pad 53, which is used to increase the friction between the gripper 52 and the pipe, prevent the pipe from sliding or rotating during the clamping process, and also has a certain protective effect on the surface of the pipe.

[0021] The position where the gripper 52 contacts the sleeve opening is set in a conical shape, and the sleeve opening is provided with an inward arc surface. The conical shape allows the gripper 52 to tighten better when the piston rod 31 retracts. The arc surface of the sleeve opening can also provide clearance, reducing the wear of the sleeve 51 on the gripper 52 and extending the service life of the gripper 52.

[0022] In actual use, depending on the work requirements, the operator can adjust the position of the hydraulic cylinder 3 by rotating the screw 23. This adjustment capability allows the gripping device 5 to move laterally on the worktable 1. When clamping the pipe, the operator places the pipe on the piston rod 31, with the bushing 54 placed inside the pipe to provide support and prevent damage to the pipe during clamping. Then, the hydraulic cylinder 3 is activated, causing the piston rod 31 to move backward, simultaneously driving the gripper 52 and the pipe to move backward. During the movement, the sleeve 51 causes the gripper 52 to continuously tighten and close, thereby clamping the pipe. After the pipe is clamped, the servo motor 4, in cooperation with the rack 12, drives the movable platform 2 to move along the first guide rail 11, sending the pipe into the welding equipment for processing. After processing, the movable platform 2 returns to its original position, the piston rod 31 moves forward, and the gripper 52, with the help of the return spring 55, can quickly release the pipe.

[0023] This design is ingenious. The clamping device 5, with its jaws 52 and bushings 54, allows for more precise and secure clamping of pipes, reducing the risk of pipe damage and improving clamping effectiveness and safety. The jaw design also allows the device to adapt to pipes of different sizes and shapes. The adjustable movable platform 2 and clamping device 5 allow the feeding device to adapt to different working requirements, improving the flexibility and adaptability of the equipment. Precise feeding and stable clamping ensure the accuracy of the processing, thereby improving product quality.

[0024] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
