Description

Technical Field

[0001] The utility model belongs to the technical field of seal installation, and particularly relates to a flexible installation device for a spring energy storage sealing ring of a piston sleeve. Background Art

[0002] In mechanical equipment, a piston sleeve is usually used to accommodate a piston body therein and achieve a sealing function, ensuring that the equipment maintains appropriate pressure and fluid control during operation. To achieve this purpose, spring energy storage sealing rings are widely used in the inner wall sealing grooves of piston sleeves to provide a lasting and reliable sealing effect. However, when installing a spring energy storage sealing ring into the annular sealing groove on the inner wall of a piston sleeve, traditional installation methods face many challenges.

[0003] In the prior art, due to the complex structure of the sealing groove on the inner wall of the piston sleeve and the relatively narrow installation space, the spring energy storage sealing ring is prone to stress concentration during installation, resulting in problems such as scratching, deformation, or even rupture. In addition, due to the lack of special installation tools, it is difficult to keep the sealing ring under uniform stress during installation, and it is easy to have situations where the positioning is inaccurate or the installation is not in place. These problems not only affect the sealing effect but also may cause a significant reduction in the service life of the sealing ring during use, increasing the frequency of equipment maintenance and replacement.

[0004] In addition, traditional installation equipment usually lacks an effective shape adjustment device, resulting in the sealing ring not being able to fit perfectly with the sealing groove after installation. Even after the initial installation is successful, due to the lack of sufficient shape adjustment of the sealing ring, problems such as loosening and offset may occur during the use of the sealing ring, leading to sealing failure. This situation is particularly prominent in high-precision and high-reliability applications, increasing the risk of equipment failure and maintenance costs.

[0005] In view of the above problems, there is an urgent need for a flexible installation device for a spring energy storage sealing ring specifically for piston sleeves. Summary of the Utility Model

[0039] See Figure 1The spring energy storage sealing ring 1 involved in the utility model comprises a high-precision jacket 101 and a spring 102 arranged in the high-precision jacket 101; the high-precision jacket 101 is a toroidal structure, made of special polytetrafluoroethylene (PTFE) material, with a V-shaped cross-section, and an open inner cavity for accommodating the spring 102 body is arranged inside, and spring body limit clamps are arranged on the upper two side edges of the open inner cavity to prevent the spring 102 from falling out during the installation and use of the sealing ring; the spring 102 is a toroidal body, and its cross-section is also V-shaped, which ensures that the spring 102 maintains an appropriate preload force in the jacket, and at the same time provides a lasting elastic sealing performance for the spring energy storage sealing ring.

[0040] The utility model uses a flexible touch-hand type installation device to non-destructively install the pre-treated spring energy storage sealing ring in the sealing groove of the piston sleeve.

[0041] The present invention will be described in detail below with reference to the specific embodiments of the drawings.

[0042] Example:

[0043] The present embodiment relates to a flexible installation device for a spring energy storage seal ring of a piston sleeve. The spring energy storage seal ring of the piston sleeve refers to a spring energy storage seal ring installed in a sealing groove circumferentially arranged on the inner wall of the piston sleeve. It should be noted that the piston sleeve referred to in the utility model, in a broad sense, not only includes sleeves in traditional hydraulic and pneumatic systems, but also covers cylindrical components used for support, guidance or sealing in different mechanical systems, and other structural elements that require inner wall sealing treatment; the inner walls of these components are provided with sealing grooves for accommodating the sealing rings to ensure effective sealing during the relative movement between the components. In traditional installation techniques, the spring energy storage seal ring needs to be stretched or compressed to be installed in the sealing groove of the piston sleeve. Therefore, this type of spring energy storage seal ring is also commonly referred to as an inner wall seal ring.

[0044] The inner wall of the piston sleeve of this embodiment is provided with an annular sealing groove, in which a spring energy storage sealing ring is flexibly installed to ensure effective sealing when the piston body and the piston sleeve 8 move relative to each other. The spring energy storage sealing ring flexible installation device of the piston sleeve mainly includes a flexible tentacle-type installation device 2, an inner cone sleeve 5 and a columnar shape adjustment device 6.

[0045] like Figure 2As shown, in this embodiment, the flexible tentacle type mounting device 2 includes a handle part 201 and a rubber flexible tentacle part 202. The handle part 201 is of a cylindrical structure. The rubber flexible tentacle part 202 includes six rubber flexible tentacles. These rubber flexible tentacles are arranged at equal intervals along the outer periphery of the handle part 201, extend horizontally, and a rigid pushing member 203 is embedded inside the ends of the rubber flexible tentacles. In this embodiment, the rigid pushing member 203 is of a U-shaped structure and is a rigid structure made of a metal material. The six rubber flexible tentacles can evenly apply pressure during the installation process of the spring energy storage sealing ring 1 to ensure that the spring energy storage sealing ring 1 maintains its shape when sliding into the sealing groove and will not be damaged.

[0046] See Figure 3 , the inner cone sleeve 5 is of a hollow cylindrical structure, which includes an installation socket 501 at one end of the hollow cylindrical structure and an inner cone guiding part 502 at the other end. The installation socket 501 is used to firmly fix the inner cone sleeve 5 at one end of the piston sleeve 8, so that the inner cone sleeve 5 can remain stable during the installation process of the spring energy storage sealing ring 1. The inner diameter of the inner cone guiding part 502 gradually decreases from the outside to the inside, so as to effectively guide the spring energy storage sealing ring 1 to smoothly enter the hollow cylinder of the inner cone sleeve 5 and then further enter the annular sealing groove of the piston sleeve 8. The spring energy storage sealing ring 1 is pushed by the flexible tentacle type mounting device 2 and passes through the inner cone guiding part 502, is gradually compressed and enters the hollow cylinder of the inner cone sleeve 5, and finally falls into the sealing groove of the piston sleeve 8. The inner cone sleeve 5 is made of a high-strength plastic or metal material. These materials not only have excellent wear resistance but also have good lubrication performance to reduce the frictional resistance between the spring energy storage sealing ring 1 and the inner cone sleeve 5 during the installation process, thereby greatly avoiding damage to the spring energy storage sealing ring 1. After the inner cone sleeve 5 is fixed to the piston sleeve 8 through its installation socket 501, a stable guiding path is provided, enabling the spring energy storage sealing ring 1 to smoothly and accurately enter the sealing groove.

[0047] See Figure 5, the columnar shaping device 6 is a tool in this embodiment for ensuring the correct positioning and shaping of the spring energy storage sealing ring 1 in the annular sealing groove of the piston sleeve 8; the columnar shaping device includes a columnar structure 601, whose outer diameter matches the inner diameter of the piston sleeve 8 to ensure close fit with the inner wall of the piston sleeve 8 during the shaping process; one end of the columnar structure 601 is provided with a conical guiding end 602, which is used to guide the columnar structure 601 to smoothly enter the inside of the piston sleeve 8, and at the same time provide preliminary shape adjustment when adjusting the position of the spring energy storage sealing ring 1; the other end of the columnar structure 601 is provided with a limiting ring 603, and the function of the limiting ring 603 is to prevent the columnar shaping device from being inserted excessively into the piston sleeve, and at the same time can be used as a rotating handle of the columnar shaping device 6. The limiting ring 603 provides a physical stop point and control point, enabling the operator to accurately control the position of the shaping device 6 and ensuring the safety and accuracy of the entire installation process; similarly, the columnar shaping device 6 is made of high-strength materials such as metal or engineering plastics, and has good wear resistance and strength.

[0048] The following introduces the flexible installation process of the spring energy storage sealing ring flexible installation device of the piston sleeve in this embodiment:

[0052] Fix one end of the piston sleeve 8 on the workbench to ensure the stability of the installation process; prepare an appropriate amount of lubricant to ensure that the spring energy storage sealing ring can slide smoothly when installed into the sealing groove, reduce friction, and prevent damage to the surface of the sealing ring.

[0053] S3: Inspection before assembly

[0054] Check the assembly drawings to ensure that the dimensions, specifications and quantities of the piston sleeve, spring energy storage sealing ring and other related parts meet the requirements; after confirmation, clean the workbench to keep the work area clean.

[0055] S4: Installation of the inner conical sleeve

[0056] Apply lubricant evenly to the inner wall of the inner conical sleeve to ensure that the lubricant covers the entire inner wall of the inner conical sleeve. Connect the installation sleeve opening of the inner conical sleeve to the piston sleeve, with the conical guiding part of the inner conical sleeve facing outward to guide the spring energy storage sealing ring to smoothly enter the inner conical sleeve and then into the sealing groove of the piston sleeve.

[0057] S5: Pretreatment of the spring energy storage sealing ring

[0058] Place the spring energy storage sealing ring on the heating plate and slowly heat it to 50°C to 100°C to soften the sealing ring. In other embodiments, the spring energy storage sealing ring can also be heated by a hot air gun or a heating box. After heating, soak the spring energy storage sealing ring in the lubricant so that its surface is evenly covered with a layer of lubricant.

[0059] S6: Install the spring energy storage sealing ring

[0060] See Figure 4 , place the heated and lubricant-soaked spring energy storage sealing ring 1 into the inner cone guiding part 502 of the inner cone sleeve 5, and then use the flexible tentacle-type installation device 2 to apply a uniform thrust to make the spring energy storage sealing ring 1 gradually advance along the inner cone sleeve 5 until it enters the piston sleeve 8 and finally slides into the sealing groove of the piston sleeve 8. That is, the flexible tentacle-type installation device 2 pushes the spring energy storage sealing ring 1 from Figure 4 position 1 in the middle to position 2 in the middle.

[0061] After completion, let it stand for at least 2 minutes to fully stabilize the state of the spring energy storage sealing ring 1.

[0062] Finally, gently pull out the flexible tentacle-type installation device 2 and disassemble the inner cone sleeve 5.

[0063] S7: Shaping operation

[0064] See Figure 6 , prepare the columnar shaping device 6 and evenly apply lubricant on its outer surface. Gradually insert the columnar shaping device 6 from one end of the piston sleeve 8. The columnar structure 601 of the columnar shaping device 6 is in close contact with the spring energy storage sealing ring 1; let it stand for more than 2 minutes to ensure that the spring energy storage sealing ring 1 is stably shaped, and then gently rotate and remove the columnar shaping device 6 to complete the shaping operation of the spring energy storage sealing ring 1.

[0065] S8: Inspection and assembly

[0066] See Figure 7 , check whether the positioning of the spring energy storage sealing ring 1 in the sealing groove of the piston sleeve 8 is accurate. After confirmation, insert the piston body into the piston sleeve 8 to complete the final assembly.
