[0027] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by way of example. In the drawings and the following description, at least some of the well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention; and, for clarity, the dimensions of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0028] The orientation terms appearing in the following description are all the directions shown in the drawings, and do not limit the specific structure of the floating seal ring pressing tooling and the floating seal ring installation system of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] In the prior art, for the alignment and installation of floating seal rings, it is usually directly manually installed by workers or the floating seal ring is held by a fixture for installation. Since the floating seal ring is composed of a metal floating ring and an O-ring, the diameter of the rubber ring is usually slightly larger than the size of the position to be assembled. During the pressing process, the rubber ring is squeezed and deformed, so that the floating ring and the assembly position can not only be dynamically connected, but also produce a sealing effect to prevent liquid leakage. Therefore, the installation of floating seal rings has high requirements for precise positioning, alignment and pressing. The floating seal rings installed manually are prone to oil leakage and damage to the working surface. In addition, the installation position of the floating seal ring is usually in a narrow space or a complex assembly structure, which poses challenges to the accessibility and operability of the floating seal ring.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present invention provides a floating seal ring pressing tool 100, which includes a sliding seat 1, a clamping member 2 and a handle 3.

[0031] The sliding seat 1 is used to connect the clamping member 2 and the handle 3, and includes two detachably connected shaft blocks 11. The two shaft blocks 11 can be combined to form a through hole 12. The shaft block 11 includes a ring segment main body 111. The ring segment main body 111 includes an inner arc surface 1111 and an outer arc surface 1112 which are oppositely arranged. The inner arc surfaces 1111 are combined to form the through hole 12. The ring segment main body 111 extends two protruding parts 112 from both sides of the outer arc surface 1112 along the first direction X away from the through hole 12.

[0032] The connection of the sliding seat 1 with the clamping member 2 and the handle 3 connects the clamping member 2 to one side surface of the through hole 12 of the sliding seat 1 in the axial direction, and connects the handle 3 to one side of the protruding part 112 along the second direction Y intersecting with the first direction X away from the through hole 12. With such a setting, the clamping member 2 can be fixed on one side surface of the sliding seat 1 in the axial direction, and the handle 3 can be fixed on one side of the protruding part 112, providing a force application point for technicians to expand the installation position of the floating seal ring 5 during operation. And during the installation process, technicians do not need to contact the installation position in a narrow space and complex structure, greatly improving the accessibility and operability of the floating seal ring 5, making the installation process more convenient and labor-saving.

[0033] The two shaft blocks 11 of the sliding seat 1 are detachably connected. A connection groove 113 is provided on the inner arc surface 1111 side of the ring segment main body 111. The two connection grooves 113 are detachably connected by inserting both ends of the core shaft 4. A first connection bolt 114 is provided through one side of the connection groove 113. The first connection bolt 114 can be screwed into the connection groove 113 to tightly press the core shaft 4 so that the core shaft 4 is in close contact with the other side of the connection groove 113 to complete the fixed connection, or it can be screwed out of the connection groove 113 to release the separation of the core shaft 4 from the other side of the connection groove 113 to achieve disassembly and separation. By adopting the detachable connection method of setting the connection groove 113 and the core shaft 4, firstly, it can provide high connection strength and stability, enabling the two shaft blocks 11 to be firmly connected. Secondly, by adjusting the length of the core shaft 4 inserted into the connection groove 113, it is convenient to flexibly adjust the connection relationship according to the different sizes of the required through holes 12, and it has flexibility and adjustability as needed. Finally, through the cooperation relationship between the core shaft 4 and the connection groove 113, it can reduce the use of parts and materials and simplify the assembly process. If it is necessary to replace or adjust the shaft block 11 components, only the core shaft 4 needs to be removed, which is convenient for disassembly and maintenance.

[0034] The two shaft blocks 11 can be joined together through the inner arc surface 1111 to form a through hole 12. The size of the through hole 12 corresponds to the size of the floating seal ring 5 to be installed, and can be adjusted within a certain range as needed, which is flexible and convenient.

[0035] On both sides of the outer arc surface 1112 of the shaft block 11, two protruding parts 112 extend away from the through hole 12 along the first direction X. The protruding parts 112 extend along the first direction X and form two sides in the second direction Y. A reserved position for connecting the handle 3 is formed on the side where the outer arc surface 1112 is located, and a reserved position for opening the connection groove 113 is formed on the side where the inner arc surface 1111 is located, which solves the problem that there are not many flat surfaces on the ring segment main body 111 and it is difficult to install other components, and facilitates the connection between the shaft block 11 and the handle 3 and between the shaft block 11 and other shaft blocks 11.

[0036] The clamping component 2 is connected to one side surface in the axial direction of the through hole 12 of the sliding seat 1, and includes a plurality of clamping arms 21 arranged in a circular shape. The clamping arms 21 are axially symmetric arc-shaped sheets with inner and outer surfaces 212 having the same radian. A connecting portion 214 protruding from the inner surface 211 in the direction close to the through hole 12 is provided on the side of the clamping arm 21 close to the shaft block 11, and is fixedly connected to the shaft block 11 through a second connecting bolt 115 axially penetrating through the shaft block 11. A positioning groove 213 recessed from the inner surface 211 in the direction close to the outer surface 212 is provided on the side of the clamping arm 21 away from the shaft block 11. The side of the positioning groove 213 close to the shaft block 11 is in positioning contact with the floating ring 51 of the floating seal ring 5 to be pressed in. The clamping arm 21 is in tight contact with the O-ring 52 of the floating seal ring 5 on the side away from the shaft block 11.

[0037] The clamping component 2 includes a plurality of clamping arms 21, which facilitate operations such as grasping, positioning, installing, and pressing the floating seal ring 5 from multiple angles, and have stronger stability and reliability.

[0038] The clamping arm 21 is an axially symmetric arc-shaped sheet with inner and outer surfaces 212 having the same radian. In the connection relationship between the clamping arm 21 and the ring segment main body 111, the centroid of the contact surface between the clamping arm 21 and the ring segment main body 111 overlaps with the centroid of the cross-section of the ring segment main body 111. In terms of the enclosed angle between the clamping arm 21 and the ring segment main body 111, the central angle θ1 corresponding to the inner arc surface 1111, the central angle θ2 of the inner and outer surfaces 212 of the clamping arm 21, and the central angle θ3 corresponding to the outer arc surface 1112 satisfy the relationship θ1 > θ2 > θ3. In the embodiment of the present invention, the central angle corresponding to the inner arc surface 1111 is 180°, the central angle corresponding to the outer arc surface 1112 is 60°, and the central angle of the inner and outer surfaces 212 of the clamping arm 21 is 120°. The clamping arm 21 is arranged at the middle position of the ring segment main body 111, and a total of three second connecting bolts 115 are arranged on both sides and the middle position of the clamping arm 21 to fixedly connect the clamping arm 21 with the shaft block 11, so that during the pressing operation, the shaft block 11 and the clamping arm 21 are evenly stressed, preventing problems such as slipping and deformation due to pressure. Setting the central angle corresponding to the inner and outer surfaces 212 of the clamping arm 21 within the range of the central angles corresponding to the inner arc surface 1111 and the outer arc surface 1112 can further improve the reliability and stability during the processes of grasping, positioning, installing, and pressing. If the central angle enclosed by the clamping arm 21 is too large, the shape is likely to be deformed due to pressure, resulting in problems such as scrapping, slipping, and wear. If the clamping arms 21 can be assembled into a complete ring, it may also cause problems such as difficulty in disassembly due to airtightness issues. If the central angle enclosed by the clamping arm 21 is too small, it is difficult to achieve the effect of quickly and accurately positioning, installing, and pressing the floating seal ring 5 by the clamping component 2, and it is also difficult to achieve a good technical effect of evenly pressing the O-ring 52.

[0039] The clamping arm 21 is fixedly connected to the shaft block 11 through the connecting portion 214 by connecting the second connecting bolt 115. Since the clamping arm 21 is an arc-shaped sheet, it is not convenient to set bolt holes penetrating the thickness direction. Therefore, a connecting portion 214 is protruded on the side close to the shaft block 11 to increase the contact area between the clamping arm 21 and the shaft block 11, and it is convenient to set bolt holes penetrating through the connecting portion 214, improving the stability and reliability of the connection.

[0040] The clamping arm 21 positions the floating ring 51 through the positioning groove 213, and then abuts the O-ring on the side of the clamping arm 21 away from the shaft block 11, so as to realize the positioning, installation and uniform pressing-in of the floating seal ring 5. The positioning groove 213 is opened on the side of the clamping arm 21 away from the shaft block 11, and the side of the positioning groove 213 close to the shaft block 11 is exactly positioned and abutted against the surface of the floating ring 51 away from the O-ring. Through such a setting, technicians can observe that the clamping arm 21 has been positioned with the floating seal ring 5. Then, the shaft blocks 11 are fixedly connected through the fastening mandrel 4 to complete the installation of the floating seal ring pressing tool 100. Subsequently, during the pressing-in process, the side of the clamping arm 21 away from the shaft block 11 tightly presses and firmly abuts against the O-ring, deforming the O-ring and evenly squeezing it into the installation space to complete the pressing-in.

[0041] The handle 3 is fixedly connected to the protruding part 112, providing a reliable force application point for technicians.

[0042] In actual use, technicians first determine the dimensions of the floating seal ring 5 and the installation position, select the shaft blocks 11, the handle 3 and the clamping arms 21 with appropriate dimensions, and install the handle 3 and the clamping arms 21 separately on multiple shaft blocks 11. After the installation is completed, the shaft blocks 11 are tightly connected through the mandrel 4 to form the floating seal ring pressing tool 100, and at the same time, the clamping arms 21 are positioned and connected to the floating seal ring. During the installation process, technicians hold the handle 3 with both hands, align the floating seal ring pressing tool 100 with the floating seal ring 5 at the installation position, and press the floating seal ring 5 with both hands at the same time to realize the uniform pressing-in of the floating seal ring 5 and quickly complete the installation. After the installation is completed, the shaft blocks 11 are disassembled by releasing the mandrel 4 to complete the entire pressing-in installation process.

[0043] The floating seal ring pressing tool 100 and the floating seal ring installation system provided by the embodiments of the present invention fix the clamping component 2 composed of multiple clamping arms 21 through the sliding seat 1 composed of multiple shaft blocks 11, realize the rapid and accurate positioning and uniform pressing-in of the floating seal ring 5, and realize the convenient and labor-saving installation by connecting the handle 3 to the sliding seat 1, avoiding problems such as damage to the floating seal ring 5.

The clamping member 2 is made of polytetrafluoroethylene material, the sliding seat 1 is made of 6061-type aluminum alloy, and the mandrel 4 is made of chromium alloy. The first connecting bolt 114 is a set screw, which is a 10.9-grade high-strength bolt with a major diameter of the thread of 5 mm and a thread length of 8 mm.
