Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breakers, and in particular to an assembly tooling for a vacuum interrupter assembly of a pole-mounted circuit breaker. Background Technology

[0002] 10kV outdoor vacuum pole-mounted circuit breakers are critical primary equipment in high-voltage power systems. Taking the ZW32 pole-mounted circuit breaker as an example, its core arc-extinguishing component, the vacuum interrupter, needs to be precisely assembled inside the insulation component. In the actual assembly process, the installation of the vacuum interrupter assembly (including the vacuum interrupter, conductive clamp, flexible connection, double-ended screw, and insulating tie rod) has the following technical characteristics: First, due to angular deviations in the flexible connection of the vacuum interrupter assembly during advancement, the threaded hole for fixing the copper rod on the flexible connection can easily misalign with the positioning hole of the insulation component. In this case, the vacuum interrupter assembly needs to be pulled out and re-aligned. Second, to ensure a complete fit between the vacuum interrupter assembly and the insulation component, a silicone rubber sealing sleeve is usually added to the outer end of the porcelain insulator of the vacuum interrupter assembly, and the inner cavity of the insulation component is designed with a conical structure. This effectively eliminates the assembly gap between the vacuum interrupter assembly and the insulation component, thereby preventing the intrusion of rainwater and other impurities during outdoor operation.

[0003] However, while this precise fit design effectively eliminates assembly gaps and prevents rainwater and impurities from entering the pole-mounted circuit breaker during outdoor operation, the tight fit between the silicone rubber sleeve and the conical cavity wall of the insulation component generates significant frictional resistance when the pressed-in vacuum interrupter assembly needs to be pulled out of the conical cavity. This greatly increases the assembly difficulty, making the entire assembly process time-consuming and labor-intensive, increasing the workload of workers, and reducing assembly efficiency. Therefore, there is an urgent need to design an assembly fixture that saves time and labor and enables efficient assembly of the vacuum interrupter assembly and insulation components. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an assembly tooling that saves time and effort and can efficiently assemble vacuum interrupter components and insulating parts.

[0005] To achieve the above objectives, this utility model provides an assembly fixture for a vacuum interrupter assembly of a pole-mounted circuit breaker, including a base, a positioning component, a support component, a limiting component, and a push-pull component. The positioning component is disposed on the base and is used to install the insulating component. The support component corresponds to and is spaced apart from the positioning component and is used to support the vacuum interrupter assembly. The limiting component is disposed on the push-pull component and is used to clamp the vacuum interrupter assembly. The push-pull component is used to drive the vacuum interrupter assembly to extend into or out of the insulating component.

[0006] Preferably, the positioning assembly includes a positioning plate and a mounting bracket. The positioning plate is vertically disposed on the base, and the positioning plate has positioning holes for the insulating component to extend into. The mounting bracket is spaced apart on the side of the positioning plate away from the support assembly and is used to install the insulating component.

[0007] Preferably, the positioning component further includes a lifting seat, which is movably mounted on the base and used to support the insulating component, and the lifting seat is provided with a flexible pad for contacting the insulating component.

[0008] Preferably, the support assembly includes a plurality of adjusting seats, which are spaced apart along the extension direction of the base. Each of the adjusting seats has a pad movably mounted on its top, and each of the pads has a groove for accommodating the vacuum interrupter assembly.

[0009] Preferably, the support assembly further includes a telescopic frame, which is movably mounted on the base, and the top of the telescopic frame is provided with a support member for abutting against the vacuum interrupter assembly.

[0010] Preferably, the limiting component includes a connecting seat and a plurality of limiting members. The connecting seat is detachably connected to the push-pull component. The plurality of limiting members are evenly and spaced along the circumference of the connecting seat and can move toward or away from the center of the connecting seat. The plurality of limiting members are all used to abut against the vacuum interrupter component.

[0011] Preferably, the push-pull assembly includes a bracket and a drive component. The bracket is disposed on the base, and the drive component is detachably mounted on the bracket. The power output end of the drive component is detachably connected to the connecting seat and is used to drive the vacuum interrupter assembly closer to or away from the insulating component.

[0012] Preferably, the top and bottom surfaces at both ends of the base are respectively provided with lifting rings and feet.

[0013] Beneficial effects:

[0014] 1. In the assembly fixture of the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model, the vacuum interrupter assembly is driven into the conical inner cavity of the insulating component by the push-pull assembly, thereby realizing the automatic assembly of the vacuum interrupter assembly and the insulating component. There is no need for the staff to manually push and pull the vacuum interrupter assembly, which not only reduces the labor intensity of the staff and saves time and effort, but also improves the assembly efficiency.

[0015] 2. In the assembly fixture of the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model, the support component enables the vacuum interrupter assembly and the insulating component to automatically maintain coaxial alignment. This not only avoids the time wasted due to repeated adjustments of the vacuum interrupter assembly and improves assembly efficiency, but also allows the silicone rubber sealing sleeve of the vacuum interrupter assembly to be uniformly pressurized in the conical inner cavity of the insulating component, preventing the silicone rubber sealing sleeve from deforming and being damaged due to local pressure. Furthermore, it can eliminate the assembly gap between the vacuum interrupter assembly and the insulating component, ensuring the tightness of the assembly.

[0016] 3. In the assembly fixture of the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model, the vacuum interrupter assembly can be clamped and fixed by the limiting component, thereby ensuring the installation stability of the vacuum interrupter assembly in the subsequent assembly process, preventing the vacuum interrupter assembly from moving randomly and affecting the assembly accuracy, and ensuring reliable use.

[0027] Example 1:

[0028] This utility model proposes an assembly tooling for a vacuum interrupter assembly of a pole-mounted circuit breaker.

[0029] In one embodiment of this utility model, an assembly fixture for a vacuum interrupter assembly of a pole-mounted circuit breaker includes a base 1, a positioning component 2, a support component 3, a limiting component 4, and a push-pull component 5. The positioning component 2 is disposed on the base 1 and is used to install the insulating component 200. The support component 3 corresponds to the positioning component 2 and is spaced apart and is used to support the vacuum interrupter assembly 100. The limiting component 4 is disposed on the push-pull component 5 and is used to clamp the vacuum interrupter assembly 100. The push-pull component 5 is used to drive the vacuum interrupter assembly 100 to extend into or out of the insulating component 200.

[0030] Working principle: The assembly fixture of the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model can install the insulating component 200 through the positioning component 2 on the base 1, and the vacuum interrupter assembly 100 is supported by the support component 3, so that the vacuum interrupter assembly 100 and the insulating component 200 can be on the same axis. At this time, the limiting component 4 clamps and fixes the vacuum interrupter assembly 100, and pushes or pulls the vacuum interrupter assembly 100 into or out of the insulating component 200 by the push-pull component 5.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, in the assembly fixture of the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model, the base 1 serves as the basic support structure of the entire fixture, providing a relatively stable working environment for each component to ensure the normal and orderly operation of the assembly of the vacuum interrupter assembly 100 and the insulating component 200. Furthermore, since the positioning component 2 is disposed on the base 1, the positioning component 2 can be a V-block or a sleeve as used in the prior art, thereby enabling the insulating component 200 to be stably installed on the positioning component 2. The structural design is simple and reasonable. Simultaneously, since the support component 3 corresponds to and is spaced apart from the positioning component 2, the vacuum interrupter assembly 100 can be stably supported by the support component 3. When the operator places the vacuum interrupter assembly 100 on the support assembly 3, the vacuum interrupter assembly 100 and the insulating component 200 automatically maintain coaxial alignment. This ensures that the advancement path of the vacuum interrupter assembly 100 corresponds to and matches the conical inner cavity of the insulating component 200. This prevents angular deviations in the flexible connection of the vacuum interrupter assembly 100 during advancement, allowing the threaded hole for fixing the copper rod on the flexible connection to align with the positioning hole of the insulating component 200 in one go. This eliminates the need for repeated pushing and pulling of the vacuum interrupter assembly 100 to adjust the assembly effect. This not only avoids wasting time due to repeated adjustments of the vacuum interrupter assembly 100 and improves assembly efficiency, but also ensures that the silicone rubber sealing sleeve of the vacuum interrupter assembly 100 is evenly compressed within the conical inner cavity of the insulating component 200, preventing deformation and damage to the silicone rubber sealing sleeve due to localized pressure. Furthermore, it eliminates the assembly gap between the vacuum interrupter assembly 100 and the insulating component 200, ensuring a tight assembly.

[0032] Understandably, since the limiting component 4 is located on the push-pull component 5, after the operator has installed and placed the insulating component 200 and the vacuum interrupter assembly 100 into position, the limiting component 4 can clamp and fix the vacuum interrupter assembly 100, thereby ensuring the installation stability of the vacuum interrupter assembly 100 during subsequent assembly processes, preventing the vacuum interrupter assembly 100 from moving freely and affecting assembly accuracy, and ensuring reliable use. Furthermore, after the limiting component 4 clamps and fixes the vacuum interrupter assembly 100, the operator can use the push-pull component 5 to drive the vacuum interrupter assembly 100 into the conical inner cavity of the insulating component 200, thereby achieving automatic assembly of the vacuum interrupter assembly 100 and the insulating component 200. This eliminates the need for the operator to manually push and pull the vacuum interrupter assembly 100, reducing the operator's labor intensity, saving time and effort, and further improving assembly efficiency. In addition, after the vacuum interrupter assembly 100 and the insulating component 200 are assembled, the operator can use the limit component 4 and the positioning component 2 to release the installation limit on the vacuum interrupter assembly 100 and the insulating component 200 respectively, so that the assembled vacuum interrupter assembly 100 and the insulating component 200 can be easily picked up and used.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the positioning assembly 2 includes a positioning plate 6 and a mounting bracket 7. The positioning plate 6 is vertically mounted on the base 1 and has positioning holes for the insulating component 200 to extend into. The mounting bracket 7 is spaced apart on the side of the positioning plate 6 away from the support assembly 3 and is used to install the insulating component 200. Specifically, the precise positioning and stable installation of the insulating component 200 are achieved through the coordinated cooperation of the positioning plate 6 and the mounting bracket 7. The vertically mounted positioning plate 6 provides an initial guiding reference for the insulating component 200 through its positioning holes, while the spaced-apart mounting bracket 7 provides final fixed support after the insulating component 200 passes through the positioning holes. This multi-point positioning and support method ensures both the positioning accuracy of the insulating component 200 and the installation stability, making it reliable in use. It should be noted that, in actual use, the assembly fixture for the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model is equipped with fasteners such as clamps or sleeves on the mounting frame 7. When the worker places the insulating component 200 on the mounting frame 7, the fasteners can further limit the installation of the insulating component 200, ensuring that the insulating component 200 does not shake or shift during the assembly process, thereby ensuring the stable operation of the entire assembly process and improving the assembly accuracy and efficiency.

[0034] In one embodiment, such as Figure 1 and Figure 2As shown, the positioning component 2 also includes a lifting seat 8, which is movably mounted on the base 1 and used to support the insulating component 200. The lifting seat 8 is provided with a flexible pad for contacting the insulating component 200. Specifically, the lifting seat 8 can be movably mounted on the base 1 using a guide rail or similar means. The lifting seat 8 itself can be adjusted in height along a direction perpendicular to the base 1 using a linear drive device such as a cylinder, hydraulic cylinder, or electric push rod. Simultaneously, the flexible pad on the top of the lifting seat 8 can be made of oil-resistant rubber or similar materials. Therefore, the combined use of the lifting seat 8 and the flexible pad not only effectively supports the insulating component 200 but also avoids damage to the outer surface of the insulating component 200, ensuring reliable operation. Understandably, after the insulating component 200 passes through the positioning hole of the positioning plate 6, its middle part is placed on the mounting bracket 7. After the operator adjusts the lifting seat 8, the end of the insulating component 200 away from the conical inner cavity naturally falls on the flexible pad of the lifting seat 8. At this time, the insulating component 200 can be limited at three points by the positioning hole, the mounting bracket 7, and the lifting seat 8, so as to ensure the absolute stability of the insulating component 200 during the assembly process and effectively prevent the insulating component 200 from shaking.

[0035] It should be noted that the assembly fixture for the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model does not require the use of a lifting seat 8 to support and limit the insulating component 200 when installing small-sized insulating parts 200. Workers can flexibly select the lifting seat 8 according to actual assembly needs. Furthermore, workers can adjust the lifting seat 8 to accommodate insulating parts 200 of different sizes, thereby meeting the assembly requirements of vacuum interrupter assemblies 100 and insulating parts 200 of various specifications, improving its flexibility and applicability.

[0036] In one embodiment, the support assembly 3 includes a plurality of adjusting seats 9, which are spaced apart along the extending direction of the base 1. A pad 10 is movably mounted on the top of each adjusting seat 9, and each pad 10 has a groove for accommodating the vacuum interrupter assembly 100. Specifically, as shown... Figure 1 and Figure 2As shown, when the vacuum interrupter assembly 100 needs to be installed, the operator places the vacuum interrupter assembly 100 on several adjusting seats 9. At this time, the adjusting seats 9 provide multi-point support for the vacuum interrupter assembly 100, thereby ensuring the stability of the vacuum interrupter assembly 100 on the base 1. Simultaneously, the adjusting seats 9 can be linear drive devices such as cylinders, hydraulic cylinders, or electric push rods, as is available in the prior art. This allows the pads 10 on the adjusting seats 9 to move up and down in a direction perpendicular to the base 1. The structural design is simple and reasonable. After the vacuum interrupter assembly 100 is placed in place, the staff adjusts the installation height of several pads 10 so that the vacuum interrupter assembly 100 and the insulating component 200 are on the same axis. This ensures that the advancement path of the vacuum interrupter assembly 100 corresponds to and matches the conical inner cavity of the insulating component 200, guaranteeing that the vacuum interrupter assembly 100 can smoothly extend into the conical inner cavity of the insulating component 200, ensuring reliable use. Furthermore, by creating grooves on several pads 10 to accommodate the vacuum interrupter assembly 100, the stability of the vacuum interrupter assembly 100 on the pads 10 can be improved.

[0037] It should be noted that when the dimensions of the vacuum interrupter assembly 100 to be assembled change, the operator can adjust the installation height of the pad 10 to adapt to and match the conical inner cavity of the corresponding insulating component 200, thereby ensuring that the vacuum interrupter assembly 100 and the insulating component 200 are in a coaxially aligned installation position, thus ensuring the tightness and reliability of the assembly, and making it flexible and convenient to use.

[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, the support assembly 3 also includes a telescopic frame 11, which is movably mounted on the base 1. The top of the telescopic frame 11 is provided with a support member 12 for abutting against the vacuum interrupter assembly 100. Understandably, since the vacuum interrupter assembly 100 typically includes a vacuum interrupter, conductive clamp, flexible connection, double-ended screw, and insulating tie rod, and due to the differences in the external dimensions of its components, in order to ensure the stable installation of the vacuum interrupter assembly 100 and prevent it from shaking or misaligning during assembly, the assembly fixture of this utility model for a pole-mounted circuit breaker vacuum interrupter assembly uses several adjusting seats 9 and pads 10 to stably support the insulating tie rod of the vacuum interrupter assembly 100. For the truncated cone-shaped vacuum interrupter, additional support and limitation are provided by the telescopic frame 11 and the support member 12 provided on the base 1.

[0039] Specifically, the telescopic frame 11 can be movably mounted on the base 1 using a sliding snap-fit ​​(such as a linear slide), allowing the telescopic frame 11 to move closer to or further away from the positioning plate 6 on the base 1. Simultaneously, the telescopic frame 11 can be a linear drive device such as a cylinder, hydraulic cylinder, or electric push rod, enabling the support member 12 to move up and down perpendicular to the base 1. This allows it to adapt to and support vacuum interrupters of different sizes and specifications, resulting in a simple and reasonable structural design. Clearly, the assembly fixture for a pole-mounted circuit breaker vacuum interrupter assembly of this utility model, through the coordinated use of the telescopic frame 11 and several adjusting seats 9, not only ensures the overall stability of the vacuum interrupter assembly 100 but also meets the assembly requirements of vacuum interrupter assemblies 100 of various sizes and specifications, expanding its application range and offering flexibility and convenience.

[0040] In one embodiment, the limiting component 4 includes a connecting seat 15 and a plurality of limiting members 16. The connecting seat 15 is detachably connected to the push-pull component 5. The plurality of limiting members 16 are evenly and spaced along the circumference of the connecting seat 15 and can move toward or away from the center of the connecting seat 15. The plurality of limiting members 16 are all used to abut against the vacuum interrupter component 100.

[0041] Understandably, such as Figure 1 and Figure 2 As shown, after the vacuum interrupter assembly 100 is placed in position, the limiting assembly 4 can clamp the vacuum interrupter assembly 100, allowing it to extend into the insulating member 200 under the action of the push-pull assembly 5. Specifically, the connecting seat 15 and the limiting assemblies 4 can be three-jaw chucks as in the prior art, and the limiting members 16 are equivalent to the jaws of the three-jaw chuck, allowing operators to manually clamp the vacuum interrupter assembly 100 with tools such as wrenches, ensuring the synchronization of movement and the stability of the connection between the vacuum interrupter assembly 100 and the push-pull assembly 5. In another embodiment, the mounting method of the plurality of limiting members 16 on the connecting seat 15 can also be a cylinder, hydraulic cylinder, or electric push rod, etc., so that the plurality of limiting members 16 can move toward or away from the center of the connecting seat 15, thereby clamping or releasing the vacuum interrupter assembly 100, thereby realizing automatic clamping of the vacuum interrupter assembly 100, eliminating the need for manual clamping operations, simplifying the operation steps, reducing the labor intensity of the workers, and improving assembly efficiency. In addition, since the plurality of limiting members 16 are evenly and spaced along the circumference of the connecting seat 15, the plurality of limiting members 16 can limit the vacuum interrupter assembly 100 at multiple points in the circumference, and thus cooperate with each other to achieve stable clamping of the vacuum interrupter assembly 100, with a simple and reasonable structural design.

[0042] In one embodiment, the push-pull assembly 5 includes a bracket 13 and a drive member 14. The bracket 13 is disposed on the base 1, and the drive member 14 is detachably mounted on the bracket 13. The power output end of the drive member 14 is detachably connected to the connecting seat 15 and is used to drive the vacuum interrupter assembly 100 closer to or further away from the insulating member 200. Specifically, as shown... Figure 1 and Figure 2 As shown, the bracket 13 provides stable support for the drive component 14, and the drive component 14 can be detachably installed on the bracket 13 by means of threaded connection, which facilitates the disassembly, replacement or maintenance of the drive component 14. At the same time, the drive component 14 can be a linear drive device such as a cylinder, hydraulic cylinder or electric push rod. When the limiting component 4 clamps and limits the vacuum interrupter assembly 100, since the power output end of the drive component 14 is detachably connected to the connecting seat 15 of the limiting component 4, the drive component 14 can drive the vacuum interrupter assembly 100 to extend into the insulating component 200, thereby realizing the automatic assembly of the vacuum interrupter assembly 100 and the insulating component 200, which saves time and effort, has high assembly efficiency, good effect and reliable use.

[0043] In one embodiment, the top and bottom surfaces at both ends of the base 1 are respectively provided with lifting rings 17 and base feet 18. Specifically, as shown... Figure 1 and Figure 2 As shown, by setting lifting rings 17 on the top surfaces at both ends of the base 1, the assembly fixture for the vacuum interrupter assembly of the pole-mounted circuit breaker of this utility model can maintain balance under various lifting postures, which is convenient for transfer or adjustment of the installation position between different work stations. By setting feet 18 on the bottom surfaces at both ends of the base 1, the stability of the base 1 can be ensured. For example, by connecting the feet 18 to the workbench with bolts, the base 1 is prevented from moving at will during the assembly process, which would affect the normal assembly of the vacuum interrupter assembly 100 and the insulating component 200. The structural design is simple and reasonable.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
