[0002] The seal is an indispensable part of the piston mechanism, and its condition is directly related to the working efficiency and safety of the piston mechanism system. During long-term use, the piston seal will need to be replaced due to wear, aging or damage. If the damaged piston seal is not replaced in time, it may cause leakage, cause environmental pollution, and even cause the normal operation of the piston mechanism, thus affecting the normal operation of the machine equipment and production safety.

However, there are the following defects: 1. The expansion during the installation process cannot form a self-locking effect, so it is necessary to prevent deformation due to external force during the installation and adjustment process, which may lead to failure of the sealing ring installation; 2. When the sealing ring is expanded, it is easy to cause the sealing ring to slip during the expansion process, resulting in expansion failure; 3. When placing the sealing ring, the sealing ring cannot be pushed, causing the sealing ring to be unable to slide off quickly, thus affecting its replacement efficiency; 4. The sealing ring replacement equipment occupies a large area, making it inconvenient to carry, and its purchase cost is also high.

[0004] In view of the above problems, the present invention provides a device for replacing a piston sealing ring of a vulcanizing mechanism to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0013] Reference Figure 1 to Figure 6 , the present invention provides a technical solution: a device for replacing a piston seal ring of a vulcanizing mechanism, comprising: a base 1, an adjusting knob 2, a plurality of positioning mounting plates 3, a worm shaft 4, a conical seat 6, a linkage mechanism 5, and a sleeve assembly 7; The adjusting knob 2 is coaxially rotatably arranged at one end of the base 1 to drive the worm shaft 4; The worm shaft 4 is coaxially rotatably disposed at the other end of the base 1, and is used to drive the positioning mounting plate 3 and the linkage mechanism 5; One end of the plurality of positioning mounting plates 3 is evenly rotated around the circumference and arranged on the base 1, and meshes with the worm shaft 4, so as to expand the piston sealing ring; The sleeve assembly 7 is fixed to the other end of the positioning mounting plate 3; the sleeve assembly 7 prevents the piston seal ring from slipping when expanding; and facilitates the piston seal ring to slip when placing; The linkage mechanism 5 is coaxially arranged on the worm shaft 4 through the conical seat 6 , and is connected to the positioning mounting plate 3 and the socket assembly 7 at the same time.

[0014] It should be noted that when the piston sealing ring is expanded and installed, the sealing ring is first placed in the inner hole of the piston, and the sealing ring is limited and clamped on the positioning mounting plate 3 through the sleeve assembly 7, and the adjusting knob 2 is turned to rotate the worm shaft 4. During the rotation of the worm shaft 4, the positioning mounting plate 3 is expanded, that is, the piston sealing ring is expanded. At the same time, during the expansion process of the sealing ring, the sleeve assembly 7 will deflect relative to the positioning mounting plate 3, which can effectively prevent the sealing ring from rolling off and prevent expansion failure.

[0015] When placing the piston sealing ring, the sealing ring will be pressed into the inner hole of the piston for position docking after expansion is completed. After docking is completed, the adjusting knob 2 is reversed to shrink the positioning mounting plate 3 under the action of the worm shaft 4. During the shrinkage process, the sleeve assembly 7 pushes the piston sealing ring under the drive of the linkage mechanism 5, so that the piston sealing ring slides off the sleeve assembly 7, even if the piston sealing ring is sleeved on the piston, thereby completing the replacement of the piston sealing ring, effectively improving the replacement efficiency and improving the portability of the replacement operation.

[0016] It should be noted that after the piston seal is installed, the outer hole diameter is larger than the inner hole diameter to facilitate the installation of the catheter.

[0017] As a preferred embodiment, the positioning mounting plate 3 includes: a worm gear 31, a support rod 32, and a first rotating shaft 33; One end of the support rod 32 is rotatably disposed on the base 1, and the other end is fixed with the sleeve assembly 7; the first rotating shaft 33 is fixed in the support rod 32; The worm wheel 31 is coaxially fixed on the connecting shaft between the support rod 32 and the base 1 , and meshes with the worm shaft 4 .

[0018] It should be noted that when the worm shaft 4 rotates, the worm wheel 31 will be synchronously driven to rotate, that is, the support rod 32 will rotate, so that the sleeve assembly 7 can expand or install the piston sealing ring.

[0019] At the same time, the direct meshing between the worm shaft 4 and the worm wheel 31 is self-locking, that is, when the adjustment knob 2 stops turning, the support rod 32 completes self-locking under the action of the worm wheel 31, thereby preventing the support rod 32 from deflecting under the action of the piston sealing ring, thereby improving the portability and accuracy of the installation.

[0020] As a preferred embodiment, the linkage mechanism 5 includes: The sun gear 51 is coaxially arranged on the conical seat 6; A telescopic adjustment rod 54, one end of which is rotatably disposed on the first rotating shaft 33, and the other end of which is hingedly provided with a slider 55; The linkage ring 52 is connected to the telescopic adjustment rod 54 through the slider 55, and a slide rail is arranged on the linkage ring 52, and the slider 55 is slidably arranged on the slide rail; There are multiple planetary gears 53, any one of which is installed between the linkage ring 52 and the sun gear 51 corresponding to the positioning mounting plate 3, and is meshed with the linkage ring 52 and the sun gear 51 at the same time; One end of the universal telescopic shaft 56 is coaxially connected to the output end of the planetary gear 53 , and the other end is connected to the socket assembly 7 .

[0021] As a preferred embodiment, the universal telescopic shaft 56 can only be adjusted for axial one-way deflection.

[0022] As a preferred embodiment, both the sun gear 51 and the linkage ring 52 are provided with limit rings, and the limit rings are used to prevent the planetary gears 53 from being out of meshing state.

[0023] It needs to be explained that when the worm shaft 4 rotates, the sun gear 51 will rotate synchronously. At the same time, the planetary gear 53 is limited by the universal telescopic shaft 56, and the linkage ring 52 is limited by the slider 55 and the telescopic adjustment rod 54, so that the planetary gear 53 can only rotate on its own when driven by the worm shaft 4, and the linkage ring 52 rotates at the same time.

[0024] When the planetary gear 53 rotates, it will drive the universal telescopic shaft 56 to rotate synchronously, and the rotation of the universal telescopic shaft 56 will drive the socket assembly 7.

[0025] As a preferred embodiment, the socket assembly 7 includes: A sleeve seat 71, one end of which is fixed on the support rod 32, and the other end of which is provided with a second rotating shaft 72; A telescopic adjustment plate 73, one end of which is rotatably disposed on the second rotating shaft 72, and the other end of which is rotatably connected to the nut 76; A rotating seat 74 is disposed in the sleeve seat 71; a lead screw 75 is rotatably disposed in the rotating seat 74; One end of the lead screw 75 is connected to the universal telescopic shaft 56, and the other end is provided with a turning handle 77; The nut 76 is threadedly connected to the lead screw 75 .

[0026] It should be noted that when expanding the piston seal ring, the piston seal ring is first placed on the telescopic adjustment plate 73, and then the adjustment knob 2 is turned to make the universal telescopic shaft 56 drive the lead screw 75 to rotate. The rotation of the lead screw 75 causes the telescopic adjustment plate 73 to rotate inward relative to the sleeve seat 71 through the nut 76, and at the same time cooperates with the sleeve seat 71 to limit the piston seal ring to prevent the piston seal ring from slipping. When placing the piston sealing ring, the adjusting knob 2 is rotated in the reverse direction to make the nut 76 rotate outward relative to the socket 71, thereby restoring the telescopic adjusting plate 73 to its initial state, that is, releasing the restriction on the piston sealing ring, thereby facilitating the piston sealing ring to slide off the telescopic adjusting plate 73 and improving the portability of the installation of the piston sealing ring.

[0027] In specific implementation, when the piston sealing ring is expanded and installed, the sealing ring is limited and clamped on the positioning mounting plate 3 through the sleeve assembly 7, and the adjusting knob 2 is rotated to drive the worm shaft 4 to expand the positioning mounting plate 3, that is, to expand the piston sealing ring. At the same time, during the expansion process of the sealing ring, the sleeve assembly 7 will deflect relative to the positioning mounting plate 3 to prevent the piston sealing ring from rolling off.

[0028] When the piston sealing ring is placed, the adjusting knob 2 is rotated in the reverse direction to drive the worm shaft 4 to shrink the positioning mounting plate 3. During the shrinkage process, the sleeve assembly 7 is driven by the linkage mechanism 5 to push the piston sealing ring, so that the piston sealing ring slides off the sleeve assembly 7, even if the piston sealing ring is sleeved on the piston, the replacement of the piston sealing ring is completed, thereby improving the replacement efficiency.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
