Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" and the like are used solely for distinction and description and should not be construed as indicating or implying relative importance.

[0030] Example 1: Figures 1 to 3 As shown, the utility model is described in an upper-mounted screw hole seat assembly tool, including a bearing plate 1, an extrusion component 2 and an abutment component 3. The bearing plate 1 is connected to the top of the valve body by bolts. A first limiting hole 4 and a second limiting hole 5 are provided on the bearing plate 1. There are two second limiting holes 5. The first limiting hole 4 is provided between the two second limiting holes 5. The second limiting hole 5 is provided in a strip structure. The extension line of the central axis of the second limiting hole 5 passes through the first limiting hole 4. The extrusion component 2 extends from the first limiting hole 4 into the valve body accommodating cavity, and the abutment component 3 extends from the second limiting hole 5 into the valve body accommodating cavity.

[0031] The extrusion component 2 includes a push rod 6 and an extrusion block 7. The push rod 6 is threadedly connected to the first limiting hole 4. The extrusion block 7 is rotatably connected to the end of the push rod 6. Twisting the push rod 6 can drive the extrusion block 7 to move upward or downward; the abutment component 3 includes a pull rod 8 and an abutment plate 9. The abutment plate 9 is used to fit the spring baffles on the left and right sides of the valve body accommodating cavity. A clamping channel 10 is also provided between the two abutment plates 9. The shape of the clamping channel 10 matches the shape of the extrusion block 7. A limiting bolt 11 is also provided at the end of the pull rod 8 located outside the valve body accommodating cavity. The limiting bolt 11 is used to limit the length of the pull rod 8 extending into the valve body accommodating cavity;

[0032] The extrusion block 7 is configured as a wedge-shaped structure. When the push rod 6 drives the extrusion block 7 to move downward, the extrusion block 7 applies a horizontal thrust on the abutment plate 9, thereby causing the two abutment components 3 to move horizontally away from each other.

[0033] By adopting the top-mounted screw hole seat assembly tooling described in the present invention, during the operation of installing the spring baffle, the push rod 6 is screwed downward, and the push rod 6 drives the extrusion block 7 to move downward; by utilizing the inclined surface cooperation between the extrusion block 7 and the two abutment plates 9, the vertical movement of the push rod 6 can be converted into the horizontal expansion movement of the abutment component 3, and then the spring baffle can be smoothly and accurately pressed into the predetermined position required by the process by the abutment plate 9, thereby improving the sealing performance and working reliability of the valve.

[0034] Specifically, in actual use of this embodiment, the operator first connects the supporting plate 1 to the top of the valve body by bolts; then moves the position of the abutment component 3 so that the abutment plate 9 fits with the spring baffle; screws the push rod 6 into the first limiting hole 4, and the extrusion block 7 at the end of the push rod 6 is installed into the clamping channel 10, and the push rod 6 is twisted so that the push rod 6 drives the extrusion block 7 to move downward. Since the extrusion block 7 is set as a wedge-shaped structure, when the extrusion block 7 moves downward, it will exert a horizontal thrust on the abutment plate 9, so that the two abutment components 3 move horizontally in the direction away from each other, so that the spring baffle can be smoothly and accurately pressed into the predetermined position required by the process by the abutment plate 9;

[0035] When the ball of the ball valve is installed in place, the push rod 6 is screwed out upward, and the push rod 6 drives the extrusion block 7 to move upward; a fitting gap is formed between the extrusion block 7 and the abutment plate 9, and then the abutment component 3 can move horizontally to separate the connecting plate from the spring baffle. At this time, the tooling can be removed from the fitting gap between the valve body and the ball.

[0036] As a preferred embodiment, based on the above method, further, a slide groove 12 is provided at the position of the clamping channel 10 of the two abutting plates 9, and a slider 13 is provided on the extrusion block 7, and the slider 13 is clamped in the slide groove 12.

[0037] In this embodiment, the cooperation between the slider 13 and the slide groove 12 enables the extrusion block 7 to smoothly push the abutment plate 9 when moving downward, avoiding misalignment between the extrusion block 7 and the abutment plate 9, and further improving the accuracy and stability of the spring baffle pressing.

[0038] As a preferred embodiment, on the basis of the above-mentioned manner, further, the extrusion block 7 and the push rod 6 are connected and matched in a detachable manner; the pull rod 8 and the abutment plate 9 are connected and matched in a detachable manner.

[0039] With this structural arrangement, after the tooling is finished using, the operator can disassemble the extrusion component 2 and the abutment component 3, which facilitates the storage and maintenance of the tooling, thereby extending the tooling's service life. Furthermore, this detachable connection allows the extrusion component 2 and the abutment component 3 to be replaced with different shapes or sizes as needed to accommodate the assembly of valves of different models or specifications, thereby increasing the tooling's versatility and flexibility.

[0040] Example 2: Figures 1 to 3 As shown, the utility model is a top-mounted screw hole seat assembly tool. On the basis of the above-mentioned method, the limit bolt 11 and the pull rod 8 are further threadedly connected. With this structural setting, the operator can adjust the position of the limit bolt 11 on the pull rod 8, thereby accurately controlling the length of the pull rod 8 extending into the valve body accommodating cavity, ensuring that the abutment plate 9 can be in the center position of the spring baffle, thereby further improving the accuracy and stability of the spring baffle press-fitting. At the same time, the limit bolt 11 and the pull rod 8 are threadedly connected, and the abutment component 3 can also be disassembled / assembled independently, which improves the convenience of using the new tool.

[0041] As a preferred embodiment, on the basis of the above method, further, the pull rod 8 includes a first rod segment 14 and a second rod segment 15, the second rod segment 15 is connected to the abutment plate 9, and the joint of the first rod segment 14 and the second rod segment 15 is arranged below the supporting plate 1, and the first rod segment 14 and the second rod segment 15 are connected into an integral structure through a threaded sleeve 16, and the outer diameter of the threaded sleeve 16 is greater than the width of the second limiting hole 5.

[0042] Specifically, in this embodiment, the threaded sleeve 16 and the limiting bolt 11 are used to abut the supporting plate 1, which can further limit the freedom of movement of the pull rod 8, and prevent the pull rod 8 from tilting when the extrusion block 7 applies a horizontal thrust on the abutment plate 9, thereby ensuring the stability of the horizontal movement of the abutment component 3, and further improving the accuracy and stability of the spring baffle press-fitting; at the same time, in this embodiment, the threaded sleeve 16 and the limiting bolt 11 are used to cooperate to enable the pull rod 8 to move linearly in the vertical direction, thereby achieving a more precise adjustment of the installation position of the abutment plate 9, ensuring that the abutment plate 9 can be aligned with the center position of the spring baffle, so that the force applied by the abutment plate 9 on the spring baffle is more balanced, and further improving the accuracy and stability of the spring baffle press-fitting.

[0043] As a preferred embodiment, on the basis of the above-mentioned manner, further, a plurality of pin holes 17 are provided on the threaded sleeve 16. With this structural arrangement, the convenience of twisting the threaded sleeve 16 can be improved.

[0044] As a preferred embodiment, based on the above manner, the supporting plate 1 is further provided with a measuring hole 18 , which is provided corresponding to the top of the abutting plate 9 , and is used for allowing a measuring ruler to pass through.

[0045] With this structural setting, during the use of the tooling, the operator can measure the installation position of the abutment plate 9 through the measuring hole 18 to ensure that the abutment plate 9 can be aligned with the center position of the spring baffle, thereby further improving the accuracy and reliability of the spring baffle press-fitting.

[0046] Example 3: Figure 1 As shown, the utility model describes an upper-mounted screw hole seat assembly tool. On the basis of the above method, further, the abutment plate 9 has a first contact surface 19 and a second contact surface 20. The first contact surface 19 is arranged at the end of the abutment plate 9, and the second contact surface 20 is arranged on the side of the abutment plate 9. The first contact surface 19 is used to fit with the spring baffle, and the second contact surface 20 is used to fit with the side of the screw hole seat. The first contact surface 19 and the second contact surface 20 are both arc structures.

[0047] This structural arrangement allows the abutment plate 9 to fit more tightly against the spring retainer and screw seat, reducing gaps during assembly and thereby improving the precision and quality of ball valve assembly. Furthermore, the second contact surface 20, in its engagement with the side surface of the screw seat, also guides the installation of the abutment plate 9, ensuring that it can be accurately and quickly positioned in the desired position during installation, thereby improving assembly efficiency.

[0048] As a preferred embodiment, on the basis of the above-mentioned manner, further, an isolation pad is provided on the surface of the first contact surface 19 , the second contact surface 20 and the extrusion block 7 , and the isolation pad is made of rubber material.

[0049] The isolation pad in this embodiment increases friction between the first and second contact surfaces 19, 20, and the extrusion block 7, the spring baffle, and the screw seat, preventing slippage during use and ensuring assembly stability. Furthermore, the rubber isolation pad has a certain degree of elasticity, providing a buffering effect during assembly, preventing damage to the spring baffle and screw seat caused by the tooling, and thus extending the service life of the valve.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
