[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, the sealing ring installation fixture of this utility model embodiment includes a base 1, a guide post 2, and a positioning ring 3. The guide post 2 is detachably connected to the base 1. The guide post 2 includes a guide section 21, a positioning section 22, and an installation section 23 connected in sequence. The guide section 21 is suitable for fitting the sealing ring 4, and the installation section 23 is adapted to the base 1 to achieve detachment. The positioning ring 3 is detachably disposed between the positioning section 22 and the base 1 for fixing and transferring the sealing ring 4. Since both the guide post 2 and the positioning ring 3 are detachable, the base 1 can be fixed to the operating platform or other mechanisms by means of screws or adhesive, which facilitates single-person operation or automated installation using a robotic arm.

[0022] According to the embodiment of the present utility model, the sealing ring installation fixture can be fixed at its initial position by setting a base 1 for the guide post 2 and the positioning ring 3. At the same time, the guide post 2 and the positioning ring 3 are detachable, which facilitates the assembly line operation of sealing ring 4 installation. Moreover, the installation fixture has a simple structure and low cost.

[0023] In one embodiment of this utility model, the base 1 includes a mounting base 11 and a positioning base 12. The positioning base 12 is fixedly mounted on the mounting base 11, and the mounting section 23 is quickly connected to the positioning base 12. Figure 1As shown, in this embodiment, the positioning seat 12 can be fixed to the mounting seat 11 by the locking screw 13. If the guide post 2 and the positioning ring 3 need to be replaced, only the positioning seat 12 can be replaced to match the guide post 2 and the positioning ring 3, without disassembling the mounting seat 11, thus improving the flexibility of the mounting fixture. In some other embodiments of this utility model, the positioning seat 12 can also be welded or glued to the mounting seat 11, and this embodiment does not impose any limitations on this.

[0024] Specifically, the positioning base 12 may be provided with a screw hole 121, and the mounting section 23 is provided with a locking round hole 231 corresponding to the screw hole 121. The ball head screw 5 fixes the guide post 2 through the screw hole 121 and the locking round hole 231. When the mounting section 23 of the guide post 2 extends into the positioning base 12, the ball head screw 5 is used to fix the guide post 2, so that there is a certain elastic clamping force between the guide post 2 and the positioning base 12. When it is necessary to remove the guide post 2 and other parts on it, it is only necessary to overcome the elastic clamping force, which makes it more convenient to remove and facilitates frequent removal of the guide post 2, so as to realize the assembly line operation.

[0025] In one embodiment of this utility model, the positioning seat 12 may be provided with a limiting part 122. The position of the limiting part 122 corresponds to the transition position between the positioning section 22 and the installation section 23, and is used to limit the positioning ring 3. This makes it easier for the bottom of the sealing ring 4 to be relatively fixed relative to the bottom of the positioning ring 3 each time the sealing ring 4 is fitted onto the positioning ring 3, thereby improving the installation accuracy. At the same time, it can also prevent the positioning ring 3 from moving toward the ball head screw 5, which would affect the removal of the guide post 2.

[0026] In one embodiment of this utility model, the length of the positioning ring 3 extending out of the positioning seat 12 is greater than or equal to the length of the sealing ring 4, so that the sealing ring 4 can be completely fitted onto the positioning ring 3, making it easy to remove the positioning ring 3 and the sealing ring 4 from the guide post 2 after the guide post 2 is removed.

[0027] In one embodiment of this utility model, the guide segment 21 may include: a first connecting segment 211, a second connecting segment 212, and a transition segment 213. The outer surface of the first connecting segment 211 is a first annular surface with a diameter of a first diameter; the outer surface of the second connecting segment 212 is a second annular surface with a diameter of a second diameter; the outer surface of the transition segment 213 is used for the transition between the first annular surface and the second annular surface, wherein the second diameter is larger than the first diameter, so that the sealing ring 4 on the first connecting segment 211 can be gradually expanded through the transition segment 213 and then moved towards the positioning ring 3 through the second connecting segment 212. In some other embodiments of this invention, the sealing ring 4 has strong elasticity and its inner diameter can be directly expanded manually to the second diameter. In this case, the guide segment 21 may not have the first connecting segment 211 and the transition segment 213, and the second connecting segment 212 can be directly used for the transition between the guide post 2 and the positioning ring 3. This embodiment does not impose any limitations on this.

[0028] In one embodiment of this utility model, the outer diameter of the positioning ring 3 is equal to the second diameter, so that the sealing ring 4 can smoothly transition from the second connecting section 212 to the positioning ring 3.

[0029] In one embodiment of this utility model, the target installation position of the sealing ring 4 is located on the cable 6, and the inner diameter of the positioning ring 3 is larger than the outer diameter of the cable, so that the positioning ring 3 can be fitted onto the cable and then the sealing ring 4 can be removed to fix it in the target installation position; at this time, the outer diameter of the positioning section 22 should be less than or equal to the inner diameter of the positioning ring 3.

[0030] In one embodiment of this utility model, the positioning ring 3 is an assembled positioning ring 3, which is composed of multiple arc-shaped segments 31 spliced ​​together, for example, from... Figure 4 The two semicircular segments are spliced ​​together, so that after the sealing ring 4 is removed from the positioning ring 3, the positioning ring 3 can be removed from the cable or the object on which the sealing ring 4 is fitted by splitting the two semicircular segments, simplifying the installation process; since the arc segment 31 has a relatively simple structure, it can accompany the cable to multiple processes, and can be removed when the sealing ring 4 needs to be fixed, adapting to various complex processes and having strong adaptability.

[0031] like Figure 5 As shown, in one embodiment of this utility model, the two ends of the arc-shaped segment 31 are respectively provided with matching convex inclined tips 311 and concave inclined grooves 312. Since the concave inclined grooves 312 and the convex inclined tips 311 are matched, they can maintain their relative positions by mutually limiting each other, thus avoiding radial misalignment when multiple identical arc-shaped segments 31 form a complete positioning ring 3. When the sealing ring 4 is fitted onto the positioning ring 3, it is impossible to separate one or more arc-shaped segments 31 radially; when the sealing ring 4 is moved out of the positioning ring 3 axially, multiple arc-shaped segments 31 can be separated freely; alternatively, one arc-shaped segment 31 can be separated from the sealing ring 4 axially first, and then the other arc-shaped segments 31 can be easily removed.

[0032] The following is combined Figure 6The working process of the sealing ring installation fixture in a specific embodiment of this utility model is as follows: (1) The convex tip 311 and concave groove 312 of the two semicircular segments are fastened together to form a complete positioning ring 3, and placed on the positioning seat 12; (2) The guide post 2 is passed through the positioning ring 3 and installed on the positioning seat 12 by ball head screw 5; (3) The sealing ring 4 is moved along the first connecting section 211, the transition section 213 and the second connecting section 212 of the guide post 2, and finally fitted onto the positioning ring 3; (4) The guide post 2 is removed, and then the positioning ring 3 fitted with the sealing ring 4 is removed; (5) The cable is passed through the inner hole formed in the positioning ring 3, so that the positioning ring 3 is fitted onto the cable; (6) The positioning ring 3 and the sealing ring 4 on it are moved to the vicinity of the target installation position, and the sealing ring 4 is moved axially to the outside of the end face of the positioning ring 3, so that the positioning ring 3 can be removed radially along the cable to complete the installation.

[0033] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing" and other such terms should be interpreted broadly.
