Description

Technical Field

[0001] This utility model relates to the technical field of hollow rod production equipment, and in particular to a QPQ hollow rod sealing device. Background Technology

[0002] QPQ hollow rods combine a special hollow structure with QPQ salt bath composite treatment technology, which greatly improves the rod's wear resistance, corrosion resistance, and fatigue resistance. They are particularly suitable for dealing with harsh working conditions, and can significantly extend equipment life, improve reliability, and reduce maintenance costs.

[0003] Existing QPQ hollow rods require an internal seal after production to ensure internal sealing. This establishes reliable isolation between different media or systems sharing the same hollow rod channel, preventing cross-contamination, interference, or contamination. It also prevents impurities from entering during storage and transportation. Current installation methods mostly involve fixing the seal in a slot or clamp. Operators or machines align the hollow rod with the seal's inner hole and apply downward force to push the rod into the seal. This is inefficient, and during insertion, the friction between the rod end and the sealing lip is downward. This downward friction attempts to push the sealing lip outward, flatten, or even flip it, rather than allowing it to extend smoothly, easily causing seal damage and deformation. Utility Model Content

Before installation, dust that may adhere to the inner wall of the positioning rod can be removed. The positioning installation is fully automatic, without the need for manual alignment and insertion adjustment. Moreover, during insertion, the seal and hollow rod move relative to each other and are inserted simultaneously. The insertion force mainly comes from the deformation of the seal material, rather than overcoming huge dynamic friction forces.

The conveying assembly 5 is disposed on one side of the first conveyor plate 41. The conveying assembly 5 includes a first movable seat 51, a second motor 52, and a first pneumatic clamp 55. The feeding assembly 6 is located at the top of the conveying chamber 4. The feeding assembly 6 includes a support base 61, a third motor 62, a third hydraulic lifting rod 66, and a second pneumatic clamp 68. The output end of the third motor 62 is connected to a second movable seat 63. The third hydraulic lifting rod 66 is provided on one side of the second movable seat 63. The output end of the third hydraulic lifting rod 66 is connected to a connecting rod 67. The end of the connecting rod 67 is provided with a second pneumatic clamp 68.

The top two sides of the second conveyor plate 73 are provided with limiting plates 71, and the inner wall surface of the limiting plate 71 is provided with positioning blocks 72.

[0019] This embodiment provides a QPQ hollow rod sealing device, which includes a rotating disk 2, an adjusting seat 3, a conveying chamber 4, a conveying assembly 5, a feeding assembly 6, and a feeding box 7. The sealing element is placed in the bearing seat 42 and conveyed into the conveying chamber 4 by the first conveying plate 41. The first hydraulic lifting rod 54 adjusts the height of the first movable seat 51 and the first pneumatic clamp 55, and clamps the sealing element after the first pneumatic clamp 55 is close to it. Then, the height is adjusted again, and the second motor 52 drives the first movable seat 51 to rotate and adjust the direction, moving the sealing element to the top of the rotating disk 2. The first hydraulic lifting rod 54 drives the first movable seat 51 to rotate and adjust the direction, moving the sealing element to the top of the rotating disk 2. As the first pneumatic clamp 51 and the first pneumatic clamp 55 move downwards, the first motor 31 drives the connecting plate 34 and the locking rod 23 to move upwards. The locking rod 23 pulls the rotating disk 2 upwards to insert the seal into the matching positioning seat 22. The hollow rod is transmitted from the outside into the feeding box 7 and gradually approaches the worktable 1 through the second conveyor plate 73. The limiting plate 71 limits and supports the hollow rod from both sides. When passing the positioning block 72, the vibrating motor drives the elastic pad and the inner hollow rod to shake. At the same time, under the action of the blower at the top, any dust and impurities that may remain on the inner wall of the hollow rod can be removed and moved to the end. The third motor 62 of the material assembly 6 adjusts the direction of the second pneumatic clamp 68, and the hydraulic cylinder 65 adjusts the height of the entire support base 61 and the second pneumatic clamp 68. After the second pneumatic clamp 68 clamps the hollow rod, it rotates and moves. The third hydraulic lifting rod adjusts the position of the second pneumatic clamp 68 to move the hollow rod to the top of the rotating disk 2. While the hydraulic cylinder 65 adjusts the second pneumatic clamp 68 to move downward, the first motor 31 drives the connecting plate 34 and the locking rod 23 to move upward. The locking rod 23 pulls the rotating disk 2 and the seals on its surface upward, tightly inserting the seals into the hollow rod. Then, the hollow rod is moved to the guide slide 81 of the unloading rack plate 8 by the feeding component 6 for unloading and conveying. This enables automatic conveying and positioning installation of the hollow rod and the seal. Before installation, any dust that may adhere to the inner wall of the positioning rod can be removed. The positioning and installation are fully automatic, without the need for manual alignment and insertion adjustment. Moreover, during insertion, the seal and the hollow rod move relative to each other and are inserted simultaneously. The insertion force mainly comes from the deformation of the seal material, rather than overcoming the huge dynamic friction force. This greatly reduces the damage and variation of the seal caused by the assembly process itself, improves the pass rate, and greatly improves the production efficiency.

[0021] In this embodiment, when the rotating disk 2 rises with the movement of the locking rod 23, the sliding rod slides upward inside the guide rod. When it descends, the pressure relief disk 24 can provide elastic support. Moreover, the operation of the drive motor can adjust the direction of the lifting seat 21 and the rotating disk 2, so that the different positioning holes 25 can be rotated to adjust their positions.
