Description

Technical Field

[0001] This utility model relates to the field of power equipment manufacturing technology, and in particular to a welding fixture for the phase support of the ZW32 enclosure. Background Technology

[0002] A 10kV outdoor vacuum pole-mounted circuit breaker is a primary device used in high-voltage power systems. It achieves closing and opening operations through an internal spring (permanent magnet) operating mechanism and a tripping spring. The circuit breaker's closing and opening performance directly affects its speed and reliability in interrupting current. During the closing and opening process, the spring operating mechanism drives transmission components (such as connecting plates and rollers) to move within the phase support slots. It is worth noting that the phase support structure of the A, B, and C phases directly determines the travel and timing parameters of the transmission components during the closing and opening process. Therefore, to ensure the circuit breaker's closing and opening performance meets standards, the travel of the three-phase transmission components must be highly consistent, and the time difference between the three-phase closing and opening must be controlled within 2ms. Thus, the welding quality of the phase support is a key factor in ensuring that the circuit breaker's parameters meet technical standards.

[0003] Currently, the welding process for phase supports typically employs a step-by-step welding method: first, the phase supports are directly welded to the reinforcing plate inside the casing, and then the welded reinforcing plate assembly is welded to the stainless steel casing plate. During this process, the welding spacing between the three phase supports must be strictly controlled to ensure that the overall performance (opening and closing) of the circuit breaker meets the requirements. However, due to the thermal deformation effect during welding, the phase supports are prone to tilting relative to the reinforcing plate, i.e., not being perpendicular to it, resulting in deviations in the welding angles and positions of the three phase supports. This deviation not only affects the welding quality but also significantly reduces the product yield. Therefore, there is an urgent need to design a welding fixture for the phase supports of the ZW32 enclosure. Utility Model Content

[0004] The main purpose of this utility model is to provide a welding fixture for the phase support of the ZW32 housing, which aims to solve the problem that the existing phase support is prone to tilting relative to the reinforcing plate during the welding process, which leads to deviations in the welding angle and position between the three phase supports, thereby affecting the welding quality and reducing the product qualification rate.

[0005] To achieve the above objectives, this utility model provides a welding fixture for a phase support bracket of a ZW32 housing, including a worktable, a positioning block, a connecting frame, fasteners, a drive assembly, and several limiting components. The positioning block is disposed on the worktable and is used to abut against a reinforcing plate. The drive assembly is disposed opposite to the reinforcing plate. The power output end of the drive assembly is detachably mounted with the connecting frame. Several limiting components for abutting against the phase support bracket are evenly and spaced on the connecting frame. The fasteners are detachably connected to the connecting frame to fix the phase support bracket onto the connecting frame.

[0006] Preferably, the connecting frame has a plurality of mounting holes evenly spaced apart, and the plurality of limiting components are respectively provided in correspondence with the plurality of mounting holes; the fastener includes a gripping part and a plurality of plug-in parts, and the plurality of plug-in parts are respectively used to pass through the connecting holes of the phase bracket and plug into the plurality of mounting holes.

[0007] Preferably, each of the limiting components includes a side plate located on the bottom surface of the connecting frame and used to abut against one side of the phase support.

[0008] Preferably, the limiting components further include baffles, which are located on the side wall of the connecting frame and spaced apart from the side plate. A mounting hole is provided between the baffle and the side plate, and the baffle is used to abut against the other side of the phase support.

[0009] Preferably, the drive assembly includes a support frame and a drive component, the drive component is vertically disposed on the support frame, and the power output end of the drive component is detachably connected to the connecting frame.

[0010] Preferably, a driving component is provided on the support frame at each position corresponding to the mounting hole.

[0011] Preferably, the cross-section of the positioning block is L-shaped.

[0012] Beneficial effects:

[0013] 1. The present invention provides a welding fixture for the phase support of the ZW32 enclosure. Through the combined use of several limiting components and fasteners, the phase support can effectively prevent the phase support from tilting relative to the reinforcing plate during the welding process, and avoid deviations in the welding angle and position between the three phase supports. This not only ensures the welding quality, but also significantly improves the product qualification rate and makes it reliable in use.

[0014] 2. In the welding fixture for the phase support of the ZW32 box of this utility model, the phase support can be abutted and limited by a number of limiting components evenly and at intervals on the connecting frame. This not only effectively prevents the phase support from shifting relative to the connecting frame during installation, but also ensures the assembly consistency between the phase support and the reinforcing plate, which is beneficial to subsequent welding operations.

[0015] 3. The welding fixture for phase support brackets of ZW32 enclosure of this utility model allows workers to install three phase supports on the connecting frame at one time using several limiting components and fasteners. The spacing between the three phase supports is equal, which eliminates the need for workers to adjust the installation position or spacing of the phase supports multiple times to ensure welding quality, simplifies the operation steps and improves welding efficiency.

[0016] 4. In the welding fixture for the ZW32 box phase support of this utility model, the positioning plate can not only provide a definite spatial position reference for the reinforcing plate, but also restrict the degree of freedom of movement of the reinforcing plate on the worktable, and prevent the reinforcing plate from shifting position during the subsequent welding process. The structural design is simple and reasonable. Attached Figure Description

[0029] Example 1:

[0030] This utility model proposes a welding fixture for the phase support of ZW32 box.

[0031] In one embodiment of this utility model, a welding fixture for a phase support bracket of a ZW32 housing includes a workbench 1, a positioning block 2, a connecting frame 3, fasteners 4, a drive assembly 5, and several limiting components 6. The positioning block 2 is disposed on the workbench 1 and is used to abut against the reinforcing plate 100. The drive assembly 5 is disposed opposite to the reinforcing plate 100. The power output end of the drive assembly 5 is detachably mounted with the connecting frame 3. Several limiting components 6 for abutting against the phase support bracket 200 are evenly and spaced on the connecting frame 3. The fasteners 4 are detachably connected to the connecting frame 3 to fix the phase support bracket 200 onto the connecting frame 3.

[0032] Specifically, such as Figures 1 to 4 As shown, the welding fixture for the ZW32 housing phase support of this utility model, during use, is equipped with a positioning block 2 on the workbench 1, allowing the operator to place the reinforcing plate 100 on the workbench 1. At this time, the positioning block 2 can serve as a reference positioning element, allowing the operator to abut the reinforcing plate 100 against the positioning block, ensuring that the installation position of the reinforcing plate 100 on the workbench 1 meets the preset installation position requirements. Thus, the positioning block not only provides a definite spatial position reference for the reinforcing plate 100, but also restricts the degree of freedom of movement of the reinforcing plate 100 on the workbench 1, preventing the reinforcing plate 100 from shifting position during subsequent welding. The structural design is simple and reasonable.

[0033] Furthermore, since the drive assembly 5 is arranged opposite to the reinforcing plate 100, the drive assembly 5 can be a linear drive device such as a cylinder, hydraulic cylinder, or electric push rod in the prior art. The power output end of the drive assembly 5 is detachably mounted with a connecting frame 3 by means of bolt connection, etc., so that the connecting frame 3 can move relative to the worktable 1 and move closer to or away from the reinforcing plate 100 under the action of the drive assembly 5. At the same time, during the use of this utility model, the operator can install the phase support 200 onto the connecting frame 3. At this time, the phase support 200 can be abutted and limited by a number of limiting components 6 evenly spaced on the connecting frame 3. This not only effectively prevents the phase support 200 from shifting position relative to the connecting frame 3 during installation, but also ensures the assembly consistency between the phase support 200 and the reinforcing plate 100, which is beneficial to subsequent welding operations. It should be noted that after the phase support 200 is placed in place, the phase support 200 can be detachably connected to the connecting frame 3 by means of fastener 4. Fastener 4 can be bolts or similar materials, which are easy to obtain, easy to assemble and disassemble, and have a compact structure. This allows the phase support 200 to be securely installed on the connecting frame 3, simplifying the operation. It is also worth noting that the number of limiting components 6 is preferably three. That is, the operator can install three phase supports 200 (corresponding to the number of phases A, B, and C) on the connecting frame 3 at one time using the limiting components 6 and fastener 4. The spacing between the three phase supports 200 is equal, thus eliminating the need for the operator to repeatedly adjust the installation position or spacing of the phase supports 200 to ensure welding quality, simplifying the operation steps and improving welding efficiency.

[0034] Understandably, after the phase support 200 is securely connected to the connecting frame 3 via the fastener 4, the operator can connect the connecting frame 3, on which the phase support 200 is mounted, to the power output end of the drive component 13. This allows the drive component 13 to move the phase support 200 on the connecting frame 3 towards the reinforcing plate 100, precisely positioning the phase support 200 against the preset position on the reinforcing plate 100 for subsequent welding operations. Clearly, this invention, through the combined use of several limiting components 6 and fasteners 4, effectively prevents the phase support 200 from tilting relative to the reinforcing plate 100 during welding, avoiding deviations in the welding angle and position between the three phase supports 200. This not only ensures welding quality but also significantly improves the product's pass rate and ensures reliable use. Furthermore, after the phase support 200 is welded to the reinforcing plate 100, the operator loosens the fasteners 4, disengaging the phase support 200 from the connecting frame 3 to reset the drive component 5. The workbench 1 is equipped with a control system for operating the drive component 5; this control system is mature existing technology and will not be described in detail here.

[0035] In one embodiment, such as Figures 1 to 4As shown, the connecting frame 3 has a plurality of mounting holes 7 evenly spaced and spaced, and a plurality of limiting components 6 are respectively provided corresponding to the plurality of mounting holes 7; the fastener 4 includes a gripping part 8 and a plurality of insertion parts 9, which are respectively used to pass through the connecting holes of the phase bracket 200 and to be inserted into the corresponding mounting holes 7. Specifically, during the process of installing the plurality of phase brackets 200 onto the connecting frame 3, the plurality of limiting components 6 can respectively abut and limit the plurality of phase brackets 200, thereby determining the installation position and spacing of the plurality of phase brackets 200; at the same time, after the plurality of phase brackets 200 are placed in place, the operator can grasp the gripping part 8 of the fastener 4, so that the plurality of insertion parts 9 of the fastener 4 pass through the connecting holes on the plurality of phase brackets 200 and are inserted into the corresponding mounting holes 7 on the connecting frame 3, thereby enabling the plurality of phase brackets 200 to be fixedly installed quickly and conveniently. This not only simplifies the operation steps and reduces the labor intensity, but also significantly improves the installation efficiency of the connecting frame 3 and the plurality of phase brackets 200, and is easy to use.

[0036] In one embodiment, each of the plurality of limiting components 6 includes a side plate 10, which is located on the bottom surface of the connecting frame 3 and is used to abut against one side of the phase support 200. Specifically, as Figures 1 to 3 As shown, the side plate 10 can be installed on the bottom surface of the connecting frame 3 by means of threaded connection, so that when the phase support 200 is installed, the staff can use the side plate 10 to abut and limit the phase support 200, thereby ensuring that the installation position of the phase support 200 on the connecting frame 3 is accurate and controllable, and that the spatial relative position of the three phase supports 200 meets the design tolerance requirements after being welded with the reinforcing plate 100.

[0037] In one embodiment, such as Figures 1 to 3 As shown, the limiting components 6 also include baffles 11, which are located on the side wall of the connecting frame 3 and spaced apart from the side plates 10. A mounting hole 7 is provided between the baffles 11 and the side plates 10. The baffles 11 are used to abut against the other side of the phase support 200. Specifically, the cooperation between the baffles 11 and the side plates 10 allows for abutment and limiting of both sides of the phase support 200, effectively constraining the movement freedom of the phase support 200 on the connecting frame 3. This prevents displacement deviation of the phase support 200 during installation, improving positioning reliability and ensuring that the relative positions of the three phase supports 200 remain highly consistent. This ensures that the welded product fully meets the design tolerance standards, significantly improving the stability and repeatability of the assembly process, and providing process assurance for subsequent high-precision welding with the reinforcing plate 100 and mass production of the product.

[0038] In one embodiment, the drive assembly 5 includes a support frame 12 and a drive member 13. The drive member 13 is vertically disposed on the support frame 12, and the power output end of the drive member 13 is detachably connected to the connecting frame 3. Specifically, as shown... Figure 1 and Figure 2 As shown, by vertically mounting the drive component 13 on the support frame 12, the support frame 12 provides a stable mounting base for the drive component 13. This allows the power output end of the drive component 13 to be quickly assembled and disassembled with the connecting frame 3 via a standardized interface. The structural design is simple and reasonable. Understandably, the vertical mounting of the drive component 13 fully utilizes the space above the workbench 1, making the overall structure of this invention more compact. Furthermore, the vertical mounting of the drive component 13 ensures that the force exerted on the reinforcing plate 100 is perpendicular to the workbench 1, effectively preventing the phase support 200 from being subjected to lateral forces and tilting relative to the connecting frame 3 during the movement of the drive component 13. This facilitates subsequent welding operations and ensures the welding quality between the phase support 200 and the reinforcing plate 100.

[0039] In another embodiment, a driving member 13 is provided on the support frame 12 at each position corresponding to the mounting hole 7. Specifically, as shown... Figures 1 to 3 As shown, each drive component 13 adopts a linear actuator with the same specifications and parameters, and achieves coordinated action through a unified control system, thereby effectively eliminating the off-center load problem caused by single-point drive of the connecting frame 3, making the phase support 200 and the reinforcing plate 100 more stable and reliable in contact with the ground.

[0040] In one embodiment, specifically, as Figure 1 and Figure 2 As shown, the cross-section of the positioning block 2 is L-shaped, which allows the positioning block 2 to abut and limit the two perpendicular side walls of the reinforcing plate 100, thereby increasing the contact and force-bearing area with the reinforcing plate 100 and effectively restricting the reinforcing plate 100 from moving freely on the workbench 1. The structural design is simple and reasonable.

[0041] 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.
