[0002] Gate valves are critical components in marine piping systems, and their valve cores require press-fitted sealing rings to ensure sealing performance. In existing technologies, the press-fitting of sealing rings largely relies on manual labor or semi-automatic equipment, resulting in problems such as poor alignment accuracy, low pressing efficiency, and potential damage to parts. For example, Chinese patent CN202111667907.X discloses a sealing ring press-fitting mechanism for a sleeve-type gate valve core. While this improves the efficiency of manual operation, it still has significant shortcomings: First, it lacks a high-precision active alignment mechanism; relying solely on simple guides makes it difficult to ensure accurate alignment between the sealing ring and the valve core axis, easily leading to press-fitting misalignment. Second, after press-fitting, the process of loosening and unloading the workpiece clamping mechanism is cumbersome, affecting overall production efficiency.

[0003] Therefore, there is an urgent need for an automated pressing mechanism that integrates high-precision centering, stable pressing, and rapid unloading functions. Utility Model Content

[0025] Working process: (Initial state) Extend the second hydraulic cylinder 13 of the centering mechanism, pushing the centering seat 14 and clamping mechanism to the right. Under the action of the action rod 19, the guide rod 18 drives the movable ring 17 to loosen, causing the spring 16 to stretch. (Feeding and centering) Insert the bottom end of the valve core 27 into the sleeve of the centering seat 14, start the second hydraulic cylinder 13 to retract, driving the centering seat 14 to move to the left, so that the fixed ring 15 and the movable ring 17 of the clamping mechanism clamp the shut-off valve core 27. The optical device 3 captures an image to determine whether the shut-off valve core 27 and the auxiliary cylinder 10 are aligned. If they are not aligned, the position of the shut-off valve core 27 can be finely adjusted by the second hydraulic cylinder 13 to correct it, thus achieving precise alignment between the sealing ring 26 and the shut-off valve core 27, significantly improving the pressing quality. (Installation of sealing ring 26 and pressing preparation) Unscrew the nut, and then rotate the bolt 12 of the connecting mechanism counterclockwise, so that the bolt 12 can be moved from the auxiliary cylinder 10 to the auxiliary cylinder 10. The auxiliary cylinder 10 is moved out of the first through hole, and then the sealing ring 26 is put on the auxiliary cylinder 10. Then the bolt 12 is turned clockwise and the threaded sleeve is tightened to fix the auxiliary cylinder 10. The motor 5 of the pressing mechanism is started, so that the bidirectional stud 6 rotates and drives a pair of abutting rods 7 to move towards each other, so that the abutting joint of the abutting rod 7 is always in contact with the outer wall of the auxiliary cylinder 10. (Pressing) The first hydraulic cylinder 8 of the hydraulic drive mechanism is started, pushing the entire pressing mechanism downward, which can press the sealing ring 26 smoothly and accurately into the predetermined groove of the valve core 27 of the shut-off valve. (Unloading) After pressing is completed, the first hydraulic cylinder 8 drives the pressing mechanism to rise and reset, the second hydraulic cylinder 13 extends, and drives the centering seat 14 to move to the right. When the end of the guide rod 18 contacts the fixed action rod 19, the movable ring 17 is pushed open, the clamping mechanism is released, and the pressed valve core 27 can be taken out, realizing rapid unloading and improving production efficiency.
