Description

Technical Field

[0001] The present invention relates to the field of sealing technology, and in particular to a sealing ring installation device and method. Background Art

[0002] The choice of sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring, which is widely used in various mechanical structures.

[0003] In the existing technology, as the application position of the sealing ring changes, the installation position structure will also change accordingly. Some sealing rings will have limiting structures on both sides of the installation position, which will cause the sealing ring to need to be expanded during the installation process. The common assembly method is to insert a hook between the sealing ring and the limiting plate, use the lever principle to pry the sealing ring into shape and gradually press it into place. The smoothness of this installation method consumes a lot of physical strength of the operator, and the installation efficiency is low. Long-term work will easily lead to a decrease in smoothness, further affecting the installation efficiency. Summary of the Invention

[0032] As a specific technical solution of this embodiment, the thread head 21 is adapted to the thread groove 19 , and the bell mouth 18 is adapted to the first expansion surface 22 .

[0033] In this embodiment, the device is divided into two main components, which are connected to the threaded head 21 and the threaded groove 19. During the connection process, the first expansion surface 22 gradually slides into the interior of the bell mouth 18. During the assembly process, the lower surface of the bell mouth 18 pushes the sealing ring to slide toward the straight part of the expansion end 2, making it easier for the sealing ring to enter its position.

[0034] As a specific technical solution of this embodiment, the first expansion surface 22 and the second expansion surface 23 are both truncated cone-shaped. The diameter of the first expansion surface 22 at the convergence end is smaller than the inner diameter of the sealing ring, and the diameter of the second expansion surface 23 at the convergence end is the same as the inner diameter of the sealing ring.

[0035] In this embodiment, the first expansion surface 22 facilitates material loading, and when the sealing ring moves in the device, the second expansion surface 23 squeezes the sealing ring from the inside to expand the sealing ring.

[0036] As a specific technical solution of this embodiment, both ends of the connecting rod 14 extend into the sliding groove 13 and contact the inner wall of the sliding sleeve 15 , and the positioning bolt 16 is threadedly connected to the connecting rod 14 .

[0037] In this embodiment, the connecting rod 14 is connected to the sliding sleeve 15 via a positioning bolt 16 . The connecting rod 14 is driven along the sliding groove 13 via the screw rod 12 , thereby driving the sliding sleeve 15 to slide up and down on the housing 1 .

[0038] As a specific technical solution of this embodiment, the push rod 17 is evenly arranged at equal intervals at the lower end of the sliding sleeve 15, and a torsion spring is provided at the connection between the push rod 17 and the sliding sleeve 15. Under the action of the torsion spring, the push rod 17 fits into the surface of the shell 1; the lower end of the push rod 17 is set to a circular arc surface close to the side of the shell 1.

[0039] In this embodiment, the arc surface of the push rod 17 contacts the second expansion surface 23 during the downward sliding of the sliding sleeve 15 and expands under the action of the inclined surface. The push rod 17 continuously generates a pushing force on the second expansion surface 23. During the resetting process of the sliding sleeve 15, the push rod 17 is reset under the action of the torsion spring and re-attaches to the surface of the shell 1.

[0040] As a specific technical solution of this embodiment, the positioning pile 25 extends to the outside of the groove 24, and the lower end of the positioning pile 25 is conical.

[0041] In this embodiment, the device is docked with the sealing ring limiting structure at the location to be installed, and the positioning piles 25 are plugged into the preset holes at the installation location to align the device.

[0042] A sealing ring installation method comprises the following steps:

[0043] S1. Loading: Put the sealing ring on the outside of the thread head 21 and slide it toward the first expansion surface 22. Insert the thread head 21 into the thread groove 19 so that the lower surface of the bell mouth 18 contacts the surface of the sealing ring.

[0044] S2. Assembly: The user rotates the expansion end 2 through the flat plate 26 to thread the thread head 21 into the thread groove 19. During the connection process, the housing 1 pushes the sealing ring to slide toward the straight portion of the expansion end 2 and finally completely fits over the straight portion of the expansion end 2.

[0045] S3. Docking: dock the assembled device to the sealing ring installation position, so that the positioning pile 25 is plugged into and aligned with the preset installation hole at the installation position, so that the lower edge of the second expansion support surface 23 is in contact with the side of the installation position;

[0046] S4. Installation: Start the drive motor 11, which drives the screw 12 to rotate. Since both ends of the connecting rod 14 are restricted by the slide groove 13 and cannot rotate, the connecting rod 14 slides along the screw 12, driving the sliding sleeve 15 to move toward the installation position. The push rod 17 pushes the sealing ring toward the bottom of the second expansion surface 23. Under the action of the inclined surface, the sealing ring expands and slides out of the second expansion surface 23. The sealing ring slides into the installation position and is tightened and fixed again.

[0047] Reference Attachment Figure 4 , where the black part is the sealing ring and the grid-shaded part is the installation location.

[0048] The working principle and use process of the present invention:

[0049] To sum up, the sealing ring installation equipment and method, by setting a second expansion surface 23 to connect with the sealing ring installation position, the diameter of the second expansion surface 23 is the same as the diameter of the side limit plate structure of the sealing ring installation position, and the push rod 17 is used to push the sealing ring to slide and expand on the second expansion surface 23. The inner diameter of the expanded sealing ring is equivalent to the diameter of the limit plate structure, and finally slides completely into the installation position under the action of the push rod 17, avoiding the obstruction of the side limit structure of the sealing ring installation position to the assembly process, improving the smoothness of the use of the sealing ring installation equipment, reducing manpower consumption, and improving installation efficiency.
